Tawsho Mining Inc. (TSX VENTURE:TAW) is pleased to report that a graphite
discovery has been made on its Cabot property in Newfoundland. The Cabot
Property consists of 102 claims which cover an area of 25.5 sq. km located
approximately 12 km north of the village Baie Verte in northwestern
Newfoundland. The property, acquired in March 2012 (see press release February
21, 2012), was known to host the Cabot Cu-sulfide prospect and the Marble Cove
Au prospect. Although graphitic metasedimentary rock units had been mapped on
the property, there is no indication that the area had been explored or actively
prospected for economic graphite prospects. Tawsho undertook during the 2012
exploration season to systematically prospect, locate, map and sample graphite
occurrences on the Cabot property.
The graphite bearing rock units, however, are rarely exposed on the Cabot
property, and where exposed, they are difficult to sample due to their recessive
weathering characteristic. The most strongly mineralized intervals occur in the
most schistose intervals within the graphitic rock units. Considerable effort
was made to take representative chip and grab samples. Given the nature of rock
exposure however, the sampling procedures could not be rigidly controlled; the
reported assay results in Table 1 only roughly estimate the average
concentration of graphite at the sampled location and will have considerable
variance.
In the course of extracting the sample from the outcrop, the graphite and host
mica schist crumbled readily compared more to the more rigid quartz-feldspar
laminae and thin beds. Consequently the sample taken may underestimate the
graphite component in the outcrop. The graphite assay results as shown in Table
1 are generally less than the subjective visual field volume percent estimate
converted to weight percent of graphite in the rock. Each value estimate
however, maintains the same relative value, i.e. higher visual graphite
estimates match the higher graphite analytical values. Coarser flake graphite
also occurs as small lenticular pods several mm in length and lenticles within
and at the margin of quartz and pegmatitic quartz-feldspar veins that cut the
graphite bearing rock unit. These veins however, due to their insignificant size
and the erratic distribution, were not sampled.
Most of the outcrops sampled were uncovered by removing the soil and/or till
cover overlying them. The lateral extent and width of the graphite bearing unit
was extended by locating mineralized outcrops on high ground and projecting
their host bedding direction across swamps and valleys where mineralized outcrop
were eventually located at their projected vicinity.

(i) Cg determined by MLA SEM
analysis
Two separate graphite bearing bands have been mapped each having an estimated
width greater than 50 meters. These bands were traced for a strike distance of
1.6 km. At their southern extent these graphite bearing bands appear to coalesce
to form a single irregularly shape lenticular pod having a width in excess of
250 meters.
At the northern margins, the graphite bearing unit is exposed in the stream as
flat outcrop several meters across where character of graphite mineralization
can be more clearly observed. Graphite lenticles having thickness of up to 4 mm
and lengths of several cm occur as intra-folia concentrations between the mica
rich layers of the schist. These lenses and lenticles are composed of mostly
massive flake graphite. The thickest graphite rich band observed was approx. 3cm
in thickness as a fracture filling associated with crenulated mica rich schist.
Most graphite rich lenticles, however, are mm in thickness and or they occur as
graphite smears on sheared surfaces.
Samples 97280 and 97315 are composite bulk samples that combined freshly broken
grab samples taken from different outcrops localities 10's of metre apart at the
sample locality. Each bulk sample size was approximately 15 kg in weight.
Composite sample 97280 was taken at the northern part of the flat lying graphite
bearing unit outcropping in the stream bed. Composite sample 97315 was taken
from a steeply sloping outcrop at the southern portion of the graphite showing
where it has the widest width. No attempt was made to select the samples as to
truly represent of the average grade of graphite at each locality.
The samples were submitted to Activation Laboratories Ltd.(Actlabs), Ancaster,
Ontario for Mineral Liberation Analysis (MLA). The sample was crushed to -2mm
particle size (- 10 mesh) and split using the A Jones riffle splitter until a
500 g sample was obtained. The 500 g sample was screened to +106/-850 micron
(+150 mesh/-20mesh) screen openings. Five grams of the crushed sample in the
size range greater than 160 microns and less than 850 microns was taken from
each sample and prepared as two polished sections. MLA scanning electron
microscope analyses determined the purity of individual graphite flakes within
individual size categories and percentage content of associated host minerals.
The report from Actlab concluded that "approximately 80% of the graphite flakes
in sample 97280 and 90% in 97315 contain inclusions or are incorporated within
phyllosilicates, quartz and feldspars." The respective samples for the total
fraction range indicated, "shows presence of 2.19 and 4.67% pure graphite,
respectively. Fine mixture of graphite and mineral matter accounts for
approximately 5.81 wt% of sample 97280 and 13.52 wt% of sample 97315" ( Actlab
Laboratory Report No.A12-12401 December 10, 2012). The total graphite content in
the large bulk sample was not separated from the host mineral component during
an MLA analysis but was estimated by petrographic modal counts on sieved
fractions of crushed material prepared as a polished thin section.
Naturally the range of flake sizes is considerably smaller than the diameter of
the crushed fragments captured on the individual screens. This study confirms
that the form of graphite is flake graphite that range from 250 microns to 6
microns in size. Less than 15% of the free graphite have sizes greater than100
microns. As noted earlier, given the nature of sampling these observed
statistics may be biased to the low side.
"The work completed on the graphite showings on the Cabot is preliminary and
much remains to be done. The grades, widths and regional extent of the graphite
mineralization are encouraging and certainly warrant the drilling of one or two
holes to obtain a true test of its grade and quality across their total width".
"We also have on the Cabot property a Cu-sulfide showing that is exposed at
surface. Preliminary examination of the outcrop exposures and available drill
core indicate that this deposit may have been separated from the main deposit by
faulting. We need to find the extension of this deposit" commented Joseph
Feldman, CEO and President, Tawsho Mining.
Since both graphite and Cu-sulfide targets respond well to VTEM and magnetometer
surveys, Tawsho contracted Geotec Ltd. Aurora, Ontario late autumn 2012 to
undertake a heliborne VTEM and Magnetometer survey on the Cabot property. This
survey has only recently been completed and the data is in the process of being
analyzed. The preliminary results are positive with well defined anomalies in
each areas of expected mineralization.
"Overall, 2012 has been a very good year for Tawsho. Results from the drill
program on the Whisker Valley were very positive as reported in our recent press
release dated January 4, 2013. We now also have a new graphite discovery on the
Cabot property, and both Cu-sulfide and Au-quartz vein showings that have been
historically drilled. Exploration on each of these prospects has advanced past
the discovery stage and Tawsho now needs to extend its activities to develop the
resource base on each prospect. By adapting a systematic approach toward
developing each of its properties, Tawsho's efforts during the last two years
even with limited budgets, are starting to bear fruit. We are now entering a new
phase of exploration in 2013. We look forward with excited anticipation to our
results as our exploration activities begin to transform prospects into
resources" concluded Joseph Feldman.

ABOUT TAWSHO MINING INC:
Tawsho is a mining exploration company focused on the acquisition, exploration
and development of gold resources and advanced stage gold exploration projects.
The Corporation is presently developing its Whisker Valley Property (comprised
of 764 claims, covering an area of 19,100 hectares, or 191 sq. km) and its Cabot
Property (comprised of 102 claims covering and area of 2,550Ha or25.5sq. km)
both located in Baie Verte Peninsula, Newfoundland and its Chevrier Property(
comprised of 557 claims, covering an area of 9542 hectares, or 95.4 sq. km)
located in the Chibougamau region of Quebec. Tawsho currently has approximately
25.2 Million shares outstanding.
Graphite Analysis, Quality Assurance/Quality Control:
Tawsho Mining is committed to a regimented QA/QC program including utilizing
standards, blanks and duplicates as per normal industry standards. Samples
collected in the field are cleaned, and organic material eliminated as much as
is possible. In this preliminary submission, additional standardized reference
material and blanks were not inserted although standard laboratory analysis did
include duplicate analysis and inserted laboratory standard. Instead, the
initial batch of samples were prepared by Eastern Analytical Ltd (Springdale NL)
and sent to two analytical laboratories: Acme analytical Laboratories
(Vancouver, BC) and ALS Canada Ltd (Vancouver, BC). The final batch of samples
were sent to Actlab-Activation Laboratories Ltd (Ancaster) for sample
preparation and graphite analysis and to Actlab (Thunder Bay, Ontario) for MLA
analysis. Rejects and pulps are returned and stored at the core shack in Baie
Verte, NL.
Acme Labs, ALS and Actlab are accredited analytical laboratories. All
laboratories have similar standard sample preparation procedures which can be
obtained from their web sites. The technique used for determining graphitic
carbon is by LECO whereby the pulp is partially digested with hydrochloric acid
to remove the inorganic carbon in carbonate minerals and then subjected to a
multistage furnace treatment
Tawsho Mining Inc. has implemented the standard QA/QC protocol for analysis and
storage of its exploration and diamond drilling. Normally, standards and
duplicate samples are randomly inserted and constitute 10% of samples submitted.
The samples are transported by a Tawsho employee from the Property to the
analytical laboratory or sealed in containers and sent by courier services to
appropriate laboratories.. Chain of custody protocols require signatures and the
maintenance of logs and receipts each time the samples are picked up from or
delivered to a new location. When utilizing commercial transportation, all
shipping sacks are sealed with a numbered tag, the removal of which is recorded
upon receipt by the analytical laboratory. The rejects samples are returned and
securely stored in a core shack/storage building in Val d'Or.
