Item 4. Information on the Company

A. History and Development of the Company

The Company was incorporated as a federal company pursuant to the laws of Canada under the Canada Business Corporations Act (the “Act”) on October 30, 1997, under the name 3430502 Canada Ltd. In December 1997, the Company changed its name to Four Crown Foods Inc. At the time, the Company was involved in the food and beverage retail business. Then in June 2000, the Company changed its name to Universal Domains Incorporated and operated in the domain registration business upon the acquisition of the license rights to a domain registration agreement for the “.cc” internet registration domain.

In November 2003, the Company ceased all operations and in September 2004, the Company changed its name to Pure Capital Incorporated. From that time until November 1, 2006, the Company’s goals were to continue to reduce the liabilities of the Company in an effort to obtain additional financing and explore the possibilities of starting a new operating business, and/or merge with or become acquired by another company or entity.

On November 27, 2006, the Company acquired full rights and title to certain mining and exploration claims located in the State of Arizona along with other equipment and properties from Redhawk Exploration & Development, Inc., a Texas corporation.

10

Then on February 6, 2007, the Company changed its name to Tombstone Exploration Corporation to reflect its current operations in the mining and exploration industry. Since that time we have been operating in the mineral resource business and the primary focus of operations has been to generate revenue from the production of silver and gold, as well as additional base minerals such as copper, lead and zinc. The goal is to produce metals and minerals at or below standard industry costs. The historical nature of mining activities of our present holdings and the acceptance of governmental agencies will enable easier startup here than in non-mining oriented locations.

Following identification of suitable areas during our drilling programs, which we anticipate will continue in the future, the Company may initiate mineral extraction if sufficient funding and permitting are secured. These efforts will provide an operating financial base from which to expand. Continuing geological research, testing and drilling is planned based on the initial geological report. This will assist in the identification of key target areas, as well as establish reserve categories.

Discussions with precious metal processing and consulting companies to assist in the design of the overall operation of our mining claims have been initiated. Relationships have already been established with refineries, assay companies and engineering firms supporting worldwide mineral processing operations.

An Application to conduct exploration trenching and drilling on the Stardust Claim block was received by the Bureau of Land Management on March 18, 2016. This work program started mid 2017 subsequent to the Company’s Reclamation Bond’s acceptance by the US Bureau of Land Management on May 17, 2017. Prior to May 2017, the Company’s Notice Application to conduct exploration drilling plan was accepted. The Company has engaged Harris Exploration Drilling and Associates, Inc., a Nevada company, to commence drilling on the Stardust Claim.

This property lies along the northern flanks of the Gila Bend Mountains, which are underlain by Precambrian schist and granitic rocks of probable Cretaceous age, uncomformably overlying and intruding the older rocks are Tertiary volcanic rocks.

12

The geology of the Stardust claims is dominated by three types or phases of granitic rocks. The age of the intrusive rocks is probably Cretaceous, but they could be Precambrian or mid-Tertiary; we currently believe they are most likely to be Cretaceous. Ninety-five percent of the mapped area is encompassed by granitic rocks. The other five percent is divided evenly between Precambrian chlorite schist and mid-Tertiary andesite dikes.

The granitics are subdivided into three units. They may all be related to the same magma or be of different ages or a combination of the two. All three are easily identifiable in the field bases on their megascopic characteristics. The first and most abundant unit is leucocratic granite. It is white in color, fine to medium-grained, and does not contain mafic minerals. The presence of chlorite is almost ubiquitous in the leuco-granite, and occurs mainly along fracture surfaces. Chlorite is probably an alteration product associated with fracturing and/or mineralization. The second granitic unit is quartz monzonite. It forms the main portion of South Hill (see Plate 1). It is equigranular and contains hornblende and biotite. Narrow (1-3) silicified and brecciated zones are hosted by this unit; and are commonly anomalous in gold. The third unit is also quartz monzonite in composition, but contains anhedral pink feldspars which distinguish it from the other two units. Alteration and mineralization are completely lacking in this unit.

Chlorite schist crops out at three localities which average about 50-75 feet in width and 300 feet in length. The schist unit is a roof pendant and probably continues at depth for only a few hundred feet. The age of the chlorite schist is probably Precambrian, based on its resemblance to other Precambrian schist units in western Arizona. Mineralization does occur within the schist, generally near andesite dikes.

The andesite dikes crop out as narrow (5-10 feet), sinuous bodies and crosscut the leucogranite and chlorite schist. Intrusion of the dikes is tentatively dated as Oligocene to early-Miocene. In the north-central position of the mapped area, the andesite seems to “blossom” into a stock-like body with minimum dimensions of 100 feet by 400 feet; see section B-B’, Plate 3 for configuration. Strike direction of the dikes varies from east-west to N70 degrees West and dips average 70 degrees to the North. Alteration of the andesite consists of silicification, brecciation, and iron-oxides; however, some andesite is devoid of alteration, especially in the eastern portion of mapped area.

Due to the paucity of outcrop on the property, structures were difficult to define. In a broad sense, the entire mapped area has been intensely fractured along an east-west structure, this fracturing is at least a ½ mile in length and 300-500 feet in width. The zone could be much wider, but colluvium to the north covers any extension.

Gold and silver mineralization with copper occurs along an east-west trend and is spatially related to an andesite dike. The dike is variably silicified and iron-stained. Silicification consists of silica replacement and drusy quart crystals in open-space veins. Hematite staining and vein fillings are commonly associated with gold.

On November 25, 2015, Zonge International completed ground geophysics across the 400 Acre claim block owned by Tombstone in the Eagletail Mining District, Yuma County, Arizona. Zonge has been well respected for geophysical data acquisition in the minerals industry since 1970. They are an industry leader in methods such as IP (induced polarization) and CSEM/AMT, as well as SP, seismic, and gravity/magnetic data acquisition. 

Zonge has performed a ground magnetic survey across the claim block to determine the extent of the Stardust Fault. Previous reports state that the two shafts on the property were sunk along a high angled structure which trends E-NE across the area of outcrop. This structure is thought to be the ‘feeder’ for the Gold Silver mineralization in the project area. Several reports reference ‘free milling gold’ from drifts along this fault. Abundant dump material contains anomalous gold and silver values as well as visible copper oxides. Due to the extensive surface disturbance in this area, performing a ground magnetic survey will give a better understanding of the subsurface character of the fault. This method details changes in density in the subsurface and is used to define faults, fractures, and changes in rock types. As a result, this geophysical data will be used to better define the Phase I scope of work, which will involve detailed surface mapping, rock/soil sampling, and delineation of drill targets.

The Stardust property has two shafts on this property that are secured with wire fencing. We have not entered either of these shafts at this time. There has been minimal surface disturbance on this property and we are not aware of any trenching, mine dumps, ponds or any contaminations released by former processing or assay/testing activities. 

The encouraging results from the rock sampling program over the Stardust project indicate the presence of a high angle detachment related precious metals vein system. The mineralization present at the Stardust project appears to be located within detachment related veins & locally intensively chloritic and hematitic host rocks. The vein system has been sampled over a strike of approximately 3,200 feet (975 meters). These veins appear to be a feeder system of an extensive partially eroded low angle fault system over the Stardust.

13

The results of the latest tranche of rock samples combined with field observations, and existing data, appear to fit the USGS detachment fault model of USGS Bulletin 2004 by Long, K.R.: Preliminary Descriptive Deposit Model for Detachment-Fault-Related Mineralization. Other productive detachment fault related precious and base metal systems occur through the Basin and Range areas of Southern California, Western Arizona, and Southern Nevada. An example in Arizona includes the Copperstone Mine, previously mined by Cypress which produced one half million ounces of gold by open pit methods from 1987-1993. Copperstone is currently being evaluated for additional resources.

Quartz veins are present in outcrop, subcrop, float, & in historical mining dumps. In addition to these strong precious metal values found in samples, additional observations at Stardust include:

The presence of chalcedonic quartz veins. 

Crushed veins & and multi-phase cemented - banded silica veins, & silicification. 

Abundant drusy textures (boiling level and vapor phase) 

Footwall host rocks are a metasediment matrix with strong hematite & intensive chloritic alteration + copper oxides.

The Property is without known Reserves and the property is exploratory in nature based on prior work on this property over many years.

The current service on this claim block has disturbances of which has been identified in our exploration plan previously filed with the BLM. Any further surface disturbance from the result of our Exploration Work that has been filed with the Bureau of Land Management will be required to be remediated.

Stardust Mine Events for years ended December 31, 2017, 2018 and 2019:

As announced on May 30, 2017, the Company’s Reclamation Bond was accepted on May 17, 2017, by the BLM, and prior to this, the Notice Application to conduct exploration drilling plan was accepted. The Company has engaged Harris Exploration Drilling and Associates Inc. (Harris Drilling), a Nevada company to commence drilling on the Stardust property the first week of June. Harris Drilling has been in business for over fifty years and has worked for many of the top mining and exploration companies in the world. This first phase drilling program is designed to establish strike length and test grades over a large enough width within the defined chlorite hematite hosted vein system. The drilling will attempt to define structural continuity (vein continuity along strike), grade of veins and hosting chl-hem zone, and find the width of structures. The program, as designed, should also demonstrate grade at reasonably shallow depths. The lowest drilling angle -45 degrees is envisioned for this program. This phase will include approximately 3000 ft of drilling. The mineralization present at the Stardust Project appears to be located within detachment related veins hosted by intensively chloritic and hematitic host rocks. The vein system has been sampled over a strike of approximately 3200 feet (975 meters). These veins appear to be a feeder system of an extensive partially eroded low angle fault system regionally present. 

As announced on July 5, 2017, the first two holes Core(HQ) of drilling were completed. The first hole (SDD1) was completed at a depth of 350 ft and the second hole (SDD2) was completed at 290ft at the 100% owned Stardust claim block located in Yuma County, Arizona. This first drill program is expected to drill 6–8 holes totaling 3000 ft. The Stardust drilling campaign is targeting an epithermal precious metals (gold, silver ) system. Harris Exploration Drilling and Associates Inc. (Harris Drilling), a Nevada company, commenced drilling on June 10th. The core samples from the first two holes were delivered to Skyline Assayers and Laboratories in Tucson, Arizona on July 3rd. The samples will be crushed and pulverized with standard steel and then proceed to be fire assayed for Gold and a 24 multi-element Geochemistry for Silver and multiple other trace elements. This first phase drilling program is designed to establish strike length and test grades over a large enough width within the defined chlorite hematite hosted vein system. The drilling will attempt to define structural continuity (vein continuity along strike), grade of veins and hosting chl-hem zone, and find the width of structures. The program, as designed, should also demonstrate grade at reasonably shallow depths. The lowest drilling angle -45 degrees is envisioned for this program. 

As announced on August 30, 2017, the third and fourth holes Core(HQ) of drilling were completed by Harris Drilling and Associates Inc. on July 26, 2017. The third hole (SDD3) was completed at a depth of 175 ft and the fourth hole (SDD4) was completed at 293 ft at the 100% owned Stardust claim block located in Yuma County, Arizona. Phase 2 drilling is scheduled for September. The Stardust drilling campaign is targeting an epithermal precious metals (gold, silver) system. The core samples from the third and fourth holes were delivered to Skyline Assayers and Laboratories in Tucson, Arizona, on July 28th. The samples will be crushed and pulverized with standard steel and then proceed to be fire assayed for gold and a 24 multi-element Geochemistry for silver and multiple other trace elements.

This first phase drilling program is designed to establish strike length and test grades over a large enough width within the defined chlorite hematite hosted vein system. The drilling will attempt to define structural continuity (vein continuity along strike), grade of veins and hosting chl-hem zone, and find the width of structures. The program, as designed, should also demonstrate grade at reasonably shallow depths. The lowest drilling angle -45 degrees is envisioned for this program.

Holes 3 and 4 are designed to test projection of gold mineralization in outcrop veins and silicification found just NE of one of the original shafts on the property. We look forwarding to receiving and reviewing the assay results and sharing with our shareholders, as there have been multiple locations of veins throughout the core that we have sent for assay.”

As announced on December 5, 2017, Nine RC drill holes totaling 5000’ were completed at the Stardust project in November. Drilling focused mostly on the western half of the property with -45 degree inclined holes. The main Stardust Mine structure, which strikes just north of due east, and secondary NE fault splays on its north side were primary targets. Drill holes across these structures consistently intercepted intervals of quartz veining, strong silicification, and associated iron oxide minerals, all prospective for gold-silver mineralization. Wall rocks to the veins included propylitically altered monzonite intrusive, meta-volcanic, and meta-sedimentary rocks. Most of the 2017 drilling occurred in an area of thin (25-90’) gravel cover created by downward offset on the N and NW sides of E-W and NE structures. Blind structural drill targets were partly resolved with the 2015 Zonge Engineering ground magnetic data, and partly discernible from detailed air photos and geologic mapping. Though the gravel contains angular fragments of gold-silver bearing, banded epithermal quartz vein material, it hindered historic development work at Stardust during the 1920’s, by obscuring in place quartz veins. 

The overall Stardust epithermal system appears differentially eroded from east to west. East of the historic mine shafts, exposures are good. Rock chip gold-silver results improve nearer to the historic Stardust mine shafts, which are located in a central corridor where the precious metals zone is better preserved from erosion, but incompletely covered by gravel. Drill holes SDR 5 and 6 tested this corridor. Drill holes SDR 7 through SDR 13 targeted quartz veins beneath gravel cover up to 300’ north and 1500’ west of the historic shafts. These holes encountered the strongest quartz vein intervals, up to 55’ thick. Quartz vein intervals were encountered through a depth range from just below the gravel cover to downhole depths up to 615’, suggesting good preservation of the precious metals zone at depth. About 1300’ west of the Stardust shaft, a prominent NE structure further down-drops tertiary volcanic rocks into fault contact with older intrusive and metamorphic rocks that host the known quartz veins. SDR 12 was collared in the hanging wall of this structure and encountered a thicker gravel sequence, tertiary volcanic rocks, and quartz veining at the fault contact between the tertiary volcanic rocks and pre-tertiary basement rocks, as well as additional quartz veins and silicification in the basement rocks. Strong alteration and structurally-controlled quartz veining continue to the western extent of the 2017 drilling, leaving the Stardust epithermal system open to the west and potentially still strengthening to the west. This drill program clearly shows the Stardust project contains an epithermal alteration system much larger and stronger than indicated by the restricted historic workings and surface exposures and requires further drilling to determine its size. The strength and extent of quartz veining and silicification observed during the drill program suggest excellent potential for significant gold and silver results. All 1000 samples are presently at Skyline Assayers and Laboratories in Tucson, Arizona. Results are expected in 4-6 weeks.

In summary, the recently completed 9-hole drill program at Stardust has successfully confirmed the presence of quartz veins outside of previously tested areas at the Stardust property. The drilling identified strong quartz vein structures along the trend for over 1500 feet west of the historic Stardust shafts. Drilling encountered quartz veins and metallic mineralization in the area outside the historic underground workings. This suggests that there could be additional precious metal resources in known structures west of the historic mines.

As announced on February 8, 2018, the Company announced the results from the phase two drill on the Stardust Gold Project as follows. Tombstone Exploration completed 13 holes totaling 6200’ at the Stardust project in 2017. Drilling focused mostly on the western half of the property with -45degree inclined holes. The main Stardust Mine structure, which strikes just north of due east, and secondary NE fault splays on its north side were primary targets. Drill holes across these structures consistently intercepted intervals of quartz veining, strong silicification, and associated iron oxide minerals, all prospective for gold-silver mineralization. Wall rocks to the veins included propylitically altered monzonite intrusive, meta-volcanic, and meta-sedimentary rocks. Most of the 2017 drilling occurred in an area of thin (25-90’) gravel cover created by downward offset on the N and NW sides of E-W and NE structures.

The overall Stardust epithermal system appears differentially eroded from east to west. East of the historic mine shafts, exposures are good. Rock chip gold-silver results improve nearer to the historic Stardust mine shafts, which are located in a central corridor where the precious metals zone is better preserved from erosion, but incompletely covered by gravel. Drill holes SDR 5 and 6 tested this corridor. Drill holes SDR 7 through SDR 13 targeted quartz veins beneath gravel cover up to 300’ north and 1500’ west of the historic shafts. These holes encountered the strongest quartz vein intervals, up to 55’ thick. Quartz vein intervals were encountered through a depth range from just below the gravel cover to downhole depths up to 615’, suggesting good preservation of the precious metals zone at depth. About 1300’ west of the Stardust shaft, a prominent NE structure further down-drops tertiary volcanic rocks into fault contact with older intrusive and metamorphic rocks that host the known quartz veins. SDR 12 was collared in the hanging wall of this structure and encountered a thicker gravel sequence, tertiary volcanic rocks, and quartz veining at the fault contact between the tertiary volcanic rocks and pre-tertiary basement rocks, as well as additional quartz veins and silicification in the basement rocks. Strong alteration and structurally-controlled quartz veining continue to the western extent of the 2017 drilling, leaving the Stardust epithermal system open to the west and potentially still strengthening to the west. To date all drill results had lower grade gold than expected on this small area of drilling. Tombstone has drilled through incredible large quartz vein intercepts with this drill campaign and nearly every section sent for assay carried gold, leaving Tombstone highly optimistic on identifying greater quantities on the remaining 396 acres of the Stardust Property.

In addition to the gold assays Tombstone also had its lab prepare Analysis of 29 additional elements which included lithium. There were interesting lithium numbers in all the drill holes of which we did not expect. Although the lithium numbers are also considered low grade it will now be added to our exploration plan. Lithium is hosted in a pregmatite composition that is similar to granite with abundant quartz. The third phase drill area has a number of pregmatite outcrops of which we will be included in our next drill targets.

The first two phases of drilling were designed to establish strike length and test grades over a large enough width within the defined chlorite hematite hosted vein system. The drilling was to define structural continuity (vein continuity along strike), grade of veins and hosting chl-hem zone, and find the width of structures.

The Company has not conducted any work at the Stardust Mine in 2019, however, the Company still holds all of the claims.

The Tombstone Project. The State of Main Mine and others as well as Section 16 of the Tombstone Mining District Copper Exploration, Cochise County, Tombstone Arizona

LOCATION: Tombstone, Arizona

OWNERSHIP: 100% Tombstone

MINERALS: Gold, Silver and Copper

PROPERTY SIZE: 641 acres

The Property is without known Reserves and the State of Main Mine is exploratory in nature based on prior work completed on this property over many years. There are multiple areas that were worked on the State of Maine Mine from the 1930’s, they have been described in many reports that previous geologists have rendered that are historic in nature. Most of this work was completed underground and access was through mine shafts and decline entrance ways. We have not completed any work in the interior of this property. We have not encountered any previous contamination on these properties related to former processing or assay testing activities. 

The Company holds the mineral rights to approximately 640 acres in the historical western Tombstone silver mining district. Our property area lies within the historic Tombstone Mining District Cochise County, Arizona. The town of Tombstone, Arizona is approximately 70 miles (miles, 110 kilometers (km)) southeast of Tucson and 24 miles (40 km) northwest of Bisbee, Arizona. The San Pedro River lies about 2 miles (3 km) west of the property’s westernmost boundary.

The Tombstone mining district is one of 12 mining districts in Cochise County, Arizona. Copper, lead, zinc, silver, and gold were the principal metals produced from the different mines in the County. Management has structured and positioned the Company to capitalize on today's increasing demand and prices for precious metals and base metals such as copper, lead and zinc.

The Tombstone property is composed of three non-contiguous parcels totaling approximately 640 acres. The parcels consist of 8 patented lode claims totaling 145.6 acres (58.9 ha) in Section 16, and 1 Arizona State Land Department (ASLD) exploration permits totaling 495 acres. The Company owns the mineral rights to the patented claims; the surface rights are owned by various individuals. The Arizona state trust lands exploration permits grant the Company the exclusive exploration rights for up to 5 years from the date the exploration applications were filed. Surface and mineral rights are variously owned by the U.S. federal government, the State of Arizona, and individual persons.

16

Tombstone has conducted multiple sampling and drill programs on Section 16 in prior years. A prior sampling program on Section 16 included 115 samples that had high gold and silver assays. The results include rock samples collected from outcrops, mine dumps, trenches, and underground workings. The two highest samples returned assayed values of 609.50 ounces per ton (opt) of Ag (silver), 0.396 opt Au (gold) and 81.70 opt Ag and 0.180 opt Au. The highest of these samples, sample 49373, was a selected sample collected from the Santa Ana mine (Joseph Vein) workings at the 18-meter level across a 10 cm. wide fault. An earlier selected high grade sample collected from the 10-meter level of the Santa Ana mine (Joseph Vein), sample SA 35-0, assayed 971.40 opt Ag, 0.335 opt Au across a 5 cm. width.

A detailed NI 43-101 was completed on this property by SRK Consulting along with a ZTEM Report by Geotech. Ltd based on Helicopter-Borne Electromagnetic Geophysical survey on the Tombstone property conducted for Tombstone Exploration Corporation. A significant Porphyry copper system has been identified that encompassed Section 16 of this district.

Facility Description:

Bonanza Mining Company (Bonanza) will operate the Harquahala Mine to reprocess historical (pre-1986) surface gold bearing ores and tailings. The operation will collect the historic ores and tailings to extract and recover the gold.

Approximately 242,000 cubic yards of historic ores and tailings will be consolidated in controlled areas prior to being sized and placed onto a newly constructed double-lined heap leach pad (approximately 314,000 square foot (sq. ft)). The gold will be extracted in the newly constructed 4,126,239 gallon double-lined pregnant solution pond, with a maximum operational storage requirement estimated to be 3,965,780 gallons. The extraction operation will consist of loading and hauling; primary and secondary crushing; agglomeration and stacking; heap leaching using cyanide solution, storage of process solutions in ponds; and precious metals recovery using granular activated carbon (GAC). The final phase of the gold extraction from the GAC will be performed off-site. The facility will also include an intermediate stockpile that will be permitted under a Type 2.02 general permit.

Updates as to Operations:

In 3rd quarter 2019, the Bonanza Mining Company (Joint Venture Company) (Bonanza) identified that their permitting engineers, CDM Smith, submitted the Air Quality permit on July 2nd and received a determination of completeness letter the same day. The completeness determination effectively starts the clock for air permit engineering review with expectations of completing the air permitting in November.

The Arizona Department of Environmental Quality (ADEQ) received the required Aquifer Protection Permit (APP) for the Bonanza Mining Company. The Department considered the application administratively complete on August 12, 2019.

The Leach Pad and construction design are now in progress for the Bonanza Gold Project and continue to progress and be ready to implement upon receiving approval of all required permits. The Company is expecting completion and approval of all the required permits for this venture during November/December 2019 and then starting the construction phase on receipt of all.

Update to the permitting:

The three permits necessary to operate are: Aquifer Protection Permit (APP), BLM Mine Plan of Operations for Public Land (MPO), and a Reclamation Plan for private property are all well into the permitting process. All permits are considered administratively complete as of December 31, 2019. 

In January 2020, Arizona State Mining Inspector concluded the Company met all criteria required to commence operations on the Bonanza Mining Project. Tombstone has completed all steps of the permitting process and is awaiting the approval of the final necessary permit to begin construction. Extensive exploration of the property has revealed significant gold and silver reserves, as previously described in the April 15, 2020 press release.

This letter states, "The Reclamation Plan submittal for the Bonanza Mining Company - Harquahala Mine Project operation has been found to meet the applicable requirements of the Mined Land Reclamation Act and the Rules and plan approval criteria as established under A.R.S. Title 27, Chapter 5, 27-971. The site is located approximately 8 miles south of Salome, La Paz County, Arizona, within Sections 15, 16, 21-23, 27 and 28, Township 4 North, Range 13 West, of the Gila and Salt River Baseline and Meridian. The site is accessed via Harquahala Mine Road and Hovatter Road from Interstate 10."

In February 2020, The Company announced the Arizona Department of Environmental Quality (ADEQ) proposes to issue an Aquifer Protection Permit (APP) for the subject facility that covers the life of the facility, including operational, closure, and post-closure periods unless suspended or revoked pursuant to Arizona Administrative Code (A.A.C.) R18-9-A213. The requirements contained in this Permit will allow the permittee to comply with the two key requirements of the Aquifer Protection Program: 1) meet Aquifer Water Quality Standards (AWQS) at the Point of Compliance (POC); and 2) demonstrate Best Available Demonstrated Control Technology (BADCT). BADCT's purpose is to employ engineering controls, processes, operating methods or other alternatives, including site-specific characteristics (i.e., the local subsurface geology), to reduce discharge of pollutants to the greatest degree achievable before they reach the aquifer or to prevent pollutants from reaching the aquifer.

Best Available Demonstrated Control Technology (BADCT):

Facilities regulated by this permit shall be designed, constructed, operated, and maintained to meet requirements specified by A.R.S. §49-243(B) and A.A.C. R18-9-A202(A)(5).

Heap Leach Pad:

This facility will cover an area of approximately 314,000 square feet, and contain approximately 242,000 cubic yards of existing gold bearing ores and tailings. The ore and tailings will be consolidated into controlled areas prior to being sized and placed on the lined leach pad. The liner system for the leach pad shall be placed on 6 inches of prepared subgrade. The bottom liner shall consist of 30-mil scrim laminated low-density polyethylene (LDPE) with LDPE film geomembrane that is equivalent to 60 mil HDPE geomembrane. The upper liner shall consist of an ultra violet (UV) resistant 45-mil double scrim high-density polyethylene (HDPE) with LDPE coating geomembrane. A uniaxial geonet shall be placed between the two liners. The liners shall be secured around the perimeter of the leach pad in an anchor trench that is 2 feet wide and 2 feet deep. A minimum of 18 inches of ¾-inch minus drain rock shall be placed on upper liner. To promote pregnant solution transfer, 3-inch and 6-inch perforated collection pipes will terminate adjacent to the 12-inch pipe, and solution will pass through the drain rock and into the 12-inch collection pipe. Two 12-inch HDPE perforated pipes shall be located in a solution collection channel near the center of the leach pad to convey solutions to the Pregnant Solution Pond. A containment berm shall be constructed 12 feet from and 2 feet higher than the adjacent toe of the leach pad. The containment berm shall be capable of containing run off a 100-year, 24-hour storm and solution drain down and routing the fluids to the Pregnant Solution Pond. Liquid collected in the containment berm will flow by gravity over the double-lined liner system before cascading over this double liner system into the pregnant solution pond. Surface water run-on shall be collected in channels capable of handling stormwater from a 100 year, 24-hour storm event and diverted around the facility. The finish grade (maximum elevation) of the heap leach pile shall not exceed 1,760 feet above mean sea level (AMSL).

Pregnant Solution Pond:

This facility shall be located adjacent to the west side of the Heap Leach Pad. Pregnant solution shall be collected in a double-lined pond having a capacity of 4,126,239 gallons including 2 feet of freeboard. The liner system for the lead pond shall be placed on 6 inches of prepared subgrade overlaid by 6 inches of geosynthetic clay liner. The bottom liner shall consist of 30-mil scrim laminated LDPE with LDPE film geomembrane that is equivalent to 60 mil HDPE geomembrane. The upper liner shall consist of an UV resistant 45-mil double scrim HDPE with LDPE coating geomembrane. A uniaxial geonet shall be placed between the two liners. The liners shall be secured around the perimeter of the pond in an anchor trench that is 2 feet wide and 2 feet deep. An LCRS sump shall be constructed between the two liners near the southeastern portion of the pond. The LCRS shall be equipped with a dedicated, automatic, fluid-level activated pump capable of pumping 15,500 gallons per day. Surface water run-on shall be collected in channels capable handling stormwater from a 100 year, 24-hour storm event and diverted around the facility.

Compliance with Aquifer Water Quality Standards (AWQS):

To ensure that site operations do not result in violation of Aquifer Water Quality Standards, the point of compliance well located 200 feet west of the Leach pad shall be sampled and analyzed for the parameters listed in Section 4.2, Table 4.2.4 in the permit. Facility inspection and operational monitoring shall be performed on a routine basis in Section 4.2, Table 4.2.1, in the permit for the Pregnant Solution Pond and the Heap Leach Pad.

Recent Developments:

February 27, 2020, the Company announced the ADEQ received the mandatory cash deposit for financial assurance for the approved cost estimate in the amount of Two hundred and Eight Thousand, Five Hundred and Fourteen dollars ($208,514) for the Aquifer Protection Permit for the Harquahala Mine Permit.

On April 15, 2020, the Company announced that it had received the final permit necessary to launch construction, and shortly after, active gold production at the Harquahala Mine. The ADEQ specifically authorized Bonanza Mining Company to “operate the Harquahala Mine, a gold mine located in an unincorporated area 8 miles south of the Town of Salome, La Paz County, Arizona” based on the issuance of AQUIFER PROTECTION PERMIT NO. P-512944, which will remain effective for the life of the facility.

The issuance of this permit allows for the construction of a 242,000 cubic yard heap leach pad and a 4,126,239 gallon double-lined pregnant solution pond, where consolidated historic ores and tailings at Harquahala will be subject to gold extraction through conventional cyanide leaching.

The initial portion of the Phase One leach pad is expected to accommodate 500,000 tons of already mined material that have been tested to show upwards or more of 26,000 - 50,000oz of gold.

19

Further, on April 21, 2020, the Company provided an update as to the status as construction begins.

Location of On-site Water Well. The Company is excited to report that the Partners have discovered an on-site water well capable of fully supplying the construction and production process at Harquahala, including the leaching extraction process following the construction of the heap leach pad. Management notes that this discovery will significantly reduce the cost of production on a per-unit basis and shorten total time to market extracted gold. 

Full Permissions in Place. Further to the Company’s release dated April 15, the Arizona Department of Environmental Quality (“ADEQ”) has now confirmed that all permissions are in place to allow for full development and Construction at the Harquahala Mine site. 

Construction Timeline. Construction of the 242,000 cubic yard heap leach pad and 4,126,239 gallon double-lined pregnant solution pond are slated to begin in May. Management now expects the construction phase to last 60-90 days, after which time the Company will begin to extract tangible gold from the site and bring it to market. 

The Bahamas Lime Rock Project

LOCATION: Freeport, Grand Bahama Island

OWNERSHIP: 100% Ownership by Bahamas Aggregates, TMBXF receives a monetary portion of every ton produced on the property.​​​​​​​

MINERALS: Limestone and Aggregates

PROPERTY SIZE: undefined

In 2019, Tombstone Exploration Corporation partnered with Bahamas Aggregates, a California corporation with operations in Freeport, Grand Bahama Island for the Bahamas Lime Rock Project. Their operation currently produces 100-120k tons of materials per month for customers in the Bahamas and United States.

Tombstone Exploration purchased a 50 cent royalty from Bahamas Aggregates High Rock operation which has reserves of four to six million tons of raw materials, creating a potential net profit of $1.5-2.5 million dollars to Tombstone. Tombstone is in discussions with Bahamas Aggregates to share in its two additional projects that have 25 million tons of aggregate reserves. 

In September 2019, Dorian, a category 5 hurricane, reached Grand Bahama Island and stalled for over a day causing devasting and serious damage to the Island with three quarters of the homes destroyed or underwater after the storm. While the damage is being repaired there is no estimate as to when the island will be able to resume normal function including operations for production of this project. Further, with the 2020 Corona virus pandemic resuming work at the project has been delayed. It is anticipated that rock sales may resume in third quarter 2020. Additionally, the loans against the Company for this project are non-recourse, while we believe the project may become profitable in the future, if it fails the loans will not be collectible.

In addition to continuing to explore our current mineral rights, we will seek out and attempt to acquire new properties.

B. Business Overview

This business generally consists of three stages: exploration, development and production. We are a mineral resource company in the exploration stage because we have not yet found mineral resources in commercially exploitable quantities, and are engaged in exploring land in an effort to discover them. Mineral resource companies that have located a mineral resource in commercially exploitable quantities and are preparing to extract that resource are in the development stage, while those engaged in the extraction of a known mineral resource are in the production stage.

Mineral resource exploration can consist of several stages. The earliest stage usually consists of the identification of a potential prospect through either the discovery of a mineralized showing on that property or as the result of a property being in proximity to another property on which exploitable resources have been identified, whether or not they are or have in the past been extracted.

20

After the identification of a property as a potential prospect, the next stage would usually be the acquisition of a right to explore the area for mineral resources. This can consist of the outright acquisition of the land or the acquisition of specific, but limited, rights to the land (e.g., a license, lease or concession). After acquisition, exploration would probably begin with a surface examination by a prospector or professional geologist with the aim of identifying areas of potential mineralization, followed by detailed geological sampling and mapping of this showing with possible geophysical and geochemical grid surveys to establish whether a known trend of mineralization continues underground, possibly trenching in these covered areas to allow sampling of the underlying rock. Exploration also commonly includes systematic regularly spaced drilling in order to determine the extent and grade of the mineralized system at depth and over a given area, as well as gaining underground access by ramping or shafting in order to obtain bulk samples that would allow one to determine the ability to recover various commodities from the rock. If minerals are found, exploration might culminate in a feasibility study to ascertain if the mining of the minerals would be economic. A feasibility study is a study that reaches a conclusion with respect to the economics of bringing a mineral resource to the production stage.

Operations

The Company has conducted several drilling programs on the Tombstone property, as described in greater detail below. 

2009/2010 Drill Program - Phase II

In February 2009, the Company extracted six additional samples from the Tombstone property which were sent to Copper State Analytical for assay for gold, silver, manganese, copper, lead and zinc. Three of the samples were taken from the State of Maine Mine and three from Randolph Mine, both located on the Tombstone property. The Company suspended the 2009 Drill Program due to general economic factors leading to difficulty in obtaining the requisite financing to fund the program.

In April 2010, the Company resumed the 2009 Drill Program, with the two targets drilled and both having intersected mineralized zones. The Company utilized a portable x-ray diffraction (XRF) machine to get on-site reading of metal levels in the drill cuttings. The results helped the exploration team manage the drilling program. Tombstone's property is underlain by Uncle Sam porphyry and units of the Bisbee Group. Mineralized fissures strike consistently northeast, and many of the fissures exhibit consistent orientation for hundreds of feet along strike. Many fissures have parallel orientations, forming fissure sets. The main mines in this area occur along these northeast-striking fissures. The State of Maine mine occurs in fissures that cut both Bisbee sediments and Uncle Sam porphyry. These structural mineralized fissures are the primary focus of the current exploration program.

As of June 30, 2010, 4,080 feet of drilling had been completed. Also, during this period, additional geologist investigation was undertaken to further assess the potential for porphyry copper exploration targets on the Tombstone property. The Company has been in contact with geophysical contractors to develop a plan, budget and timeline for this phase of the project. Planning is on-going and work may include geochemical surveys as well.

The Company has not conducted further drilling on the Tombstone Property since June 2010. The State of Main mine is without known Reserves and the property is exploratory in nature based on prior work on this property over many years.

2010 Report on a Helicopter-Borne Z-Axis Tipper Electromagnetic (ZTEM) and Aero Magnetic Geophysical Survey

From June 29, 2010 to July 4, 2010, Geotech Ltd. carried out a helicopter-borne geophysical survey for the Company over the Tombstone project area. Principal geophysical sensors included a Z-Axis Tipper electromagnetic (ZTEM) system, and a caesium magnetometer. Ancillary equipment included a GPS navigation system and a radar altimeter. ZTEM was selected for its ability to achieve unparalleled resolution and depth of investigation. The system is well suited to imaging buried porphyry deposits and is capable of gathering data over 6,000 feet (1.25 miles) below ground surface.

The airborne ZTEM survey covered over 200 line miles and most of the Tombstone Mining District. A total of 373.5 line kilometers of geophysical data were acquired during the survey. In a ZTEM survey, a single vertical-dipole air-core receiver coil is flown over the survey area in a grid pattern, similar to regional airborne EM surveys. Two orthogonal, air-core horizontal axis coils are placed close to the survey site to measure the horizontal EM reference fields. Data from the three coils are used to obtain the Z/X and Z/Y Tipper (Vozoff, 1972) components at six frequencies in the 30 to 720 Hz band. The ZTEM was used to map geology using resistivity contrasts and magnetometer data were also collected to help map geology using magnetic susceptibility contrasts.

21

The crew was based in Tombstone, Arizona for the acquisition phase of the survey. Survey flying started on June 29, 2010 and was completed on July 4, 2010. Data quality control and quality assurance, and preliminary data processing were carried out on a daily basis during the acquisition phase of the project. Final reporting, data presentation and archiving were completed from the Aurora office of Geotech Ltd. in October, 2010. A quality control step consisted of re-examining all data in order to validate the preliminary data processing and to allow for final adjustments to the data. Attitude corrections were re-evaluated, and re-applied, on component by component, flight by flight, and frequency by frequency bases. Any remaining line to line system noise was removed by applying a mild additional levelling correction.

As a result of the survey, Geotech identified a number of conductive structures across the property that resemble known porphyry deposits and reported that the magnetic results also contained worthwhile information in support of exploration targets of interest. Based on the geophysical results obtained, Geotech recommended a more detailed interpretation of the available geophysical data, including Versatile Time-Domain Electromagnetic survey (VTEM), in conjunction with the geology, prior to ground follow up and drill testing.

In November 2010, upon review of the ZTEM data, at least four to five porphyry targets were identified on the Company's Tombstone property, and there is still a very large land position to review. Of the targets that have been identified so far, two have precious metal (gold and silver) occurrences as "halos" around the properties, which are significant characteristics of porphyry systems. One identified structure has been compared by Geotech to the Mount Milligan deposits that were sold and have total measured and indicated resources of 417.1 million tons grading 0.21% copper, 0.41 g/t gold for 1,934 million pounds copper and 5.5 million ounces gold. Three of the identified targets have coincident magnetic and resistivity high which are very promising geophysical signatures. One target is adjacent to a porphyry system that was drilled by a major international mining company. As of the date of this Report, the Company is continuing to work with the geophysical data acquired from the ZTEM survey of the Tombstone Project. 

2012 Technical Report

In January 2012, SRK completed a Technical Report on the Tombstone property.

SRK made the following conclusions in the Report:

The Tombstone property represents a beginning exploration project with a limited amount of historical and current data. The data are insufficient to take the property to resource classification by current industry standards at this time.

The historic silver deposits in the central mining district are well documented through various reports in the literature and several master- and doctoral-level theses. Although west of the largest historical ore deposits, the Tombstone West Area property nonetheless represents an opportunity to target a resource by current methodologies of mapping, drilling, and geophysical surveys that may be successfully extracted with present-day mining techniques. In light of silver commodity price increases in recent years, the recent emphasis on potential porphyry copper and gold targets in the Tombstone area, and recent gold and copper commodity prices, the Tombstone Project warrants a current evaluation.

SRK made the following recommendations in the Report:

2017 drill program

The Company completed 13 holes totaling 6200’ at the Stardust project in 2017. Drilling focused mostly on the western half of the property with -45 degree inclined holes. The main Stardust Mine structure, which strikes just north of due east, and secondary NE fault splays on its north side were primary targets. Drill holes across these structures consistently intercepted intervals of quartz veining, strong silicification, and associated iron oxide minerals, all prospective for gold-silver mineralization. Wall rocks to the veins included propylitically altered monzonite intrusive, meta-volcanic, and meta-sedimentary rocks. Most of the 2017 drilling occurred in an area of thin (25-90’) gravel cover created by downward offset on the N and NW sides of E-W and NE structures.

22

The overall Stardust epithermal system appears differentially eroded from east to west. East of the historic mine shafts, exposures are good. Rock chip gold-silver results improve nearer to the historic Stardust mine shafts, which are located in a central corridor where the precious metals zone is better preserved from erosion, but incompletely covered by gravel. Drill holes SDR 5 and 6 tested this corridor. Drill holes SDR 7 through SDR 13 targeted quartz veins beneath gravel cover up to 300’ north and 1500’ west of the historic shafts. These holes encountered the strongest quartz vein intervals, up to 55’ thick. Quartz vein intervals were encountered through a depth range from just below the gravel cover to downhole depths up to 615’, suggesting good preservation of the precious metals zone at depth. About 1300’ west of the Stardust shaft, a prominent NE structure further down-drops tertiary volcanic rocks into fault contact with older intrusive and metamorphic rocks that host the known quartz veins. SDR 12 was collared in the hanging wall of this structure and encountered a thicker gravel sequence, tertiary volcanic rocks, and quartz veining at the fault contact between the tertiary volcanic rocks and pre-tertiary basement rocks, as well as additional quartz veins and silicification in the basement rocks. Strong alteration and structurally-controlled quartz veining continue to the western extent of the 2017 drilling, leaving the Stardust epithermal system open to the west and potentially still strengthening to the west. To date all drill results had lower grade gold than expected on this small area of drilling. Tombstone has drilled through incredible large quartz vein intercepts with this drill campaign and nearly every section sent for assay carried gold, leaving Tombstone highly optimistic on identifying greater quantities on the remaining 396 acres of the Stardust Property.

In additition to the gold assays Tombstone also had its lab prepare Analysis of 29 additional elements which included lithium. There were interesting lithium numbers in all the drill holes of which we did not expect. Although the lithium numbers are also considered low grade it will now be added to our exploration plan. Lithium is hosted in a pregmatite composition that is similar to granite with abundant quartz. The third phase drill area has a number of pregmatite outcrops of which we will be included in our next drill targets.

The first two phases of drilling were designed to establish strike length and test grades over a large enough width within the defined chlorite hematite hosted vein system. The drilling was to define structural continuity (vein continuity along strike), grade of veins and hosting chl-hem zone, and find the width of structures.

⁽²⁾We raised $1,933,000 during the year ended December 31, 2019 to cover the operating expenses of the Company and require an additional ~$3M for our proposed 2020 activities. Funds raised in 2019 for our operations included $1,571,000 for purchase of common stock and $362,000 in non-recourse promissory notes which are secured against the future revenues of the Company, bears interest at 15% per annum, and is due in quarterly payments commencing April 30, 2019 through to January 31, 2021.  

Revenues

To date we have not generated any revenues.

Principal Market

We do not currently have any market, as we have not yet identified any mineral resource on the Tombstone Property that is of a commercially exploitable quantity. If we succeed in identifying a mineral resource in commercially exploitable quantities, our principal markets should consist of metal refineries and base metal traders and dealers.

26

Seasonality of our Business

Our mineral exploration activities are not subject to extreme seasonal variation since the Tombstone Property is located in Arizona. Field work, however, is best carried out in temperatures averaging 10 to 15 degrees Celsius. Our other operations, such as metallurgical review and analysis of geochemical survey results, can be carried out all year round.

Local Resources

Tombstone, Arizona is the nearest town to the Tombstone Project. Services at Tombstone are marginally adequate to support the requirements of a mining exploration and development project, but other nearby towns (Wilcox, Benson, Bisbee, and Sierra Vista) have services such as drilling contractors, equipment rental and services, engineering services, and a labor force that are more able to support our drilling program. Sierra Vista is about 18 miles from the project area. The nearest large city, Tucson—located 70 miles northwest of Tombstone along Interstate 10—has a population of more than 526,116 (2013 U.S. Census Bureau estimate) and has company, service, and contractor resources that may not be available locally. Other cities at a greater distance (Phoenix, Arizona; Las Cruces and Albuquerque, New Mexico) also are able to provide services to support exploration and mining in the area.

Surface water is scarce and groundwater supplies are somewhat limited. Walnut Gulch to the north is an ephemeral stream, as is the San Pedro River to the west. In 1882 a pipeline was constructed to bring drinking water to Tombstone from the Huachuca Mountains, 27 miles to the west. The town has municipal wells that supply the needs of the town population. Ranchers in outlying areas obtain domestic and stock water from private wells. Water supplies for development and mining would come from groundwater sources in the area. Arizona Department of Water Resources (ADWR) well records for the area indicate the water table is generally shallow, 200 to 400 feet below ground surface.

Telephone and electric power are available to the area, providing service to local ranchers and small service companies located outside of the town. Telephone service is provided by Qwest. Internet and television services also are available locally. Electric power is supplied through Sulphur Springs Valley Electric Cooperative, with 440V, three-phase lines nearby. One-ten and 220 power lines cross the property. Postal services are available by post office boxes and ground delivery. UPS, DHL, and Federal Express also are available locally.

Gas and diesel stations are 2 miles from the property, and major fuel supply stations are 15 miles away in Sierra Vista. El Paso Gas has a gas line that crosses the northeast corner of Sec. 7, T20S-R22E. Section 7 is held by Arizona State Exploration Permit 08-111864. The Southern Pacific railroad line parallels the San Pedro River.

Patents and Licenses; Industrial, Commercial and Financial Contracts; and New Manufacturing Processes

In conducting our business operations, we are not dependent on any patented or licensed processes, technology, industrial, commercial or financial contract or new manufacturing processes.

Competitive Conditions

We compete with other mining companies, some of which have greater financial resources and technical facilities, for the acquisition of mineral interests, as well as for the recruitment and retention of qualified employees.

The mineral property exploration business, in general, is intensely competitive and there is not any assurance that even if commercial quantities of ore are discovered, a ready market will exist for sale of the same. Numerous factors beyond our control may affect the marketability of any substances discovered. These factors include market fluctuations; the proximity and capacity of natural resource markets and processing equipment; and government regulations, including regulations relating to prices, taxes, royalties, land tenure, land use, importing and exporting of mineral and environmental protection. The exact effect of these factors cannot be accurately predicted, but the combination of these factors may make it difficult for us to receive an adequate return on investment.

We compete with many companies possessing greater financial resources and technical facilities for the acquisition of mineral concessions, claims, leases and other mineral interests as well as for the recruitment and retention of qualified employees. Low metal prices and an instable market, even among competition, leads us to assume that we will not face any difficulties retaining geologists or other consultants compared to our competition.

Competition in the usual context, and as experienced by manufacturers of automobiles, durable goods, clothing, electronics, and the providers of most services simply is not a factor in the minerals market. The demand for minerals always exceeds supply, and historically prices have consistently risen. The only major factor for competition is the cost of production.

27

Although competition over cost of production exists, there is little competition in the marketplace for the Company’s products. The market absorbs all precious metals and most base metals produced at prevailing prices. Larger producers can hedge future production to enable easier management of expected revenue in times of price fluctuation, whereas junior companies usually sell at market prices. In today’s market larger producers have pulled back from hedging.

The primary competition in the precious metals market is for talent in the workforce. As prices have risen many new companies have started operations or are in the midst of exploration and proving of reserves. It is in this area that competition exists for experienced geologists, project managers, and mining executives. In many areas there also is a shortage of mining labor.

The Company believes it can overcome this competition due to its location in a historical mining area, year-round working conditions and nearness to major population centers of Tucson and Phoenix, Arizona. Additionally, experienced mining professionals have assisted in developing the corporation and have many contacts in the industry.

Environmental Regulations

Mineral property exploration in Arizona is governed by the State of Arizona Office of Mine Inspector as well as Title 30 of the Code of Federal Regulations, both seek to regulate and promote the development of safe and environmentally conscious mining operations. To date, our compliance with these regulations has had no material effect on our operations, capital, earnings, or competitive position, and the cost of such compliance has not been material. We are unable to assess or predict at this time what effect additional regulations or legislation could have on our activities.

Governmental Regulations

Mining operations are subject to a wide range of government regulations such as restrictions on production, price controls, tax increases, expropriation of property, environmental protection, protection of agricultural territory or changes in conditions under which minerals may be marketed. Mining operations may also be affected by claims of native peoples, any of which could have the effect of reducing or preventing us from exploiting any of our properties. We will be required to comply with all regulations, rules and directives of governmental authorities and agencies applicable to the exploration of minerals in the State of Arizona and in the United States generally. Our mineral claims entitle our Company to continue exploration activities on our properties, subject to our compliance with various United States federal and state laws governing land use, the protection of the environment and related matters.

To maintain state mineral exploration permits in good standing, the permit holder must renew each permit annually (up to four times, for 5 years total) for a fee of $500.00 per application for renewal. A maximum of 640 acres or one whole section is allowed per application. Additionally, an initial rental fee of $2.00 per acre is due within thirty days upon notification of the intent to issue the permit. The $2.00 rental fee is for the first and second year of the permit. However, although the rent is prepaid for the second year, the permit must still be renewed for that year. Rental fees for years three thru five are $10.00 per acre per year and due annually when the permit is renewed. A bond (typically in the amount of $3,000 for a single permit or a blanket bond of $15,000 for five or more permits held by an individual or company) is also due within thirty days upon notification of the intent to issue the permit. Bond amounts may be increased during the life of the permit as determined by the Arizona State Land Department (“ASLD”) upon review of the proposed exploration activities as detailed in the Exploration Plan of Operation that must be submitted and approved by the ASLD prior to the startup of any exploration activities.

The state lands are covered by Arizona State Mineral Exploration Permits, which are administered by the ASLD. Permits to conduct drilling in Arizona are administered by the Arizona Department of Water Resources (ADWR). Permits to conduct exploration drilling on BLM lands require either a Notice of Intent or a Plan of Operations, depending upon the amount of new surface disturbance that is planned. A Notice of Intent is for planned surface activities that anticipate less than 5.0 acres of surface disturbance, and usually can be obtained within a 30 to 60 day time period. A Plan of Operations will be required if there is greater than 5.0 acres of new surface disturbance involved with the planned exploration work. A Plan of Operations can take several months to be approved, depending on the nature of the intended work, the level of reclamation bonding required, the need for archeological surveys, and other factors as may be determined by the BLM. No other permits are required for exploration drilling.

The Company has a Notice of Intent – Mineral Exploration Drilling AZA33591 to conduct drilling on BLM claims in Secs. 9 and 10, T20S-R22E. The permitted drilling was partially completed in 2007 with the drilling of holes TEM 1, TEM 2, and TEM 3. The Company also has received conditional approval, upon completion of archaeological and cultural resource surveys, to drill in Sec. 16, T20SR22E under Arizona State Exploration Permit 08-111868.

Quality Control Procedures (QA/QC)

Bagged and sealed sample splits from the RC drill holes are transported to a secure storage shed at the office site by Company employees. The dry samples are further reduced by crushing them to 3/4 inch-minus with a “chipmunk” jaw crusher and splitting the crushed sample with a riffle splitter. The crusher and the splitter are then both cleaned with a brush and compressed air after preparation of each sample. The sample splits for the laboratory are reduced to approximately 10 lbs or less prior to submission to the laboratory. The prepared samples are bagged, labeled, and sealed and taken to the analytical laboratory, Mountains States R&D International, Inc. (MSRDI), an Arizona certified assay laboratory, in Vail, Arizona for analyses by fire assay (gold and silver) and by atomic absorption (AA) (all other analyses). The splits that are not shipped for assay are reduced to approximately 1 lb to be retained for reference at the project site and they are stored in a secure steel shipping storage container.

Laboratory rejects are discarded during the process of reducing sample splits to approximately 1 lb samples for retention. The retained sample splits are derived from the original samples and kept in storage while another split is sent for analysis. The pulps are retained and stored in a locked onsite office building.

Samples collected from other locations in the project area (surface outcrops, mine dumps, trenches, and underground workings) are collected, bagged, labeled, sealed, logged, and transported. The samples are prepared for storage or for shipment to the analytical laboratory in the following manner: Dry samples are reduced by first crushing them to 3/4 inch-minus with a “chipmunk” jaw crusher and then splitting the crushed sample using a riffle splitter. The crusher and splitter are then both cleaned with a brush and compressed air after preparation of each sample. Wet samples are dried and then processed in the same manner. The prepared samples are bagged, labeled, and sealed and taken to MSRDI for analysis. The splits that are not shipped for assay are retained for reference at the project site in a secure storage container.

All sampling and sample preparation of coarse crushed (3/4 inch-minus) are conducted by the Company’s employees. Sample pulp preparation is conducted at MSRDI. All samples are shipped to MSRDI. All gold and silver analyses are obtained by fire assay. All other analyses (Cu, Pb, and Zn) are obtained by atomic absorption (AA) with standard digestion.

Samples collected from surface sites, trenches, underground workings, and the 2007 drilling program (prior to November 2007) did not include blanks, duplicates, reference standards, or other industry standard QA/QC procedures.

Quality control procedures began at the Tombstone Project approximately November 2007. Ten samples collected underground from the Santa Ana mine (NE¼ NE¼ Sec. 16, T20S-R22E) on October 30, 2007 were submitted to the laboratory (MSRDI) with blanks and reference standards. The reference samples were obtained from Minerals Exploration and Environmental Chemistry, Reno, Nevada. Blanks were prepared by crushing and bagging cinder blocks. Results received for these samples are used to assess the accuracy of the MSRDI analyses. Check samples on the order of 5 to 10 percent of the number of samples were sent to ALS Chemex, Reno, Nevada and from there were forwarded to their laboratory in Canada for analysis. The pulps that were returned from the primary laboratory were used as the check-sample materials.

Samples are stored at the Company office site in a secure storage container or in the Company laboratory, which is locked during nonworking hours.

As of the date of our Technical Report, April 18, 2008, SRK concluded that the sampling procedures were acceptable and within industry standards with the exception of initial sample preparation by the Company. Coarse crushed sample preparation onsite by the property owner is not common industry standard practice unless logistics and distance from the labs are a major factor. It may be acceptable going forward, if the newly implemented QA/QC procedures incorporate sufficient checks to demonstrate that the initial sample preparation imparts no contamination or bias. 

C. Organizational Structure

We have one wholly owned subsidiary, Tombstone Exploration and Mining Corporation, a Nevada corporation (“TEMC”) that is qualified to do business in the State of Arizona. All of our operations are conducted through TEMC.

D. Property, Plants and Equipment

Our principal executive office is located at 6529 E. Friess Drive, Scottsdale, AZ 85254. Additionally, we share this space with our wholly owned subsidiary, TEMC. Pursuant to our lease executed January 1, 2016, we rent both office and storage space for $1,000 per month for a 5 year term. We believe that this existing space is adequate for our current needs. Should we require additional space, we believe that such space can be secured on commercially reasonable terms.
