Fredonia Mining Inc. (“Fredonia” or the “Company”) (TSXV: FRED) is
pleased to announce the successful completion of the first of two
phases of its drilling program at its flagship Eldorado Monserrat
(“EDM”) property, located in Santa Cruz, Argentina.
On the La Herradura project 1,583.5m of drilling
were completed. Additionally, 1,841m was drilled on the Monserrat
Oeste project for which assays are awaited.
Phase one of the La Herradura drilling consisted
of six HQ diamond drill holes for a total of 1,583.5m. Over
1,142 samples (including standards, blanks and duplicates) were
submitted for gold fire assays and multielement ICP to Alex Stewart
(a certified laboratory). Not all assays have been return for the
last hole, HDDH034 and these will be reported separately.
"We are very excited about the results obtained
so far at La Herradura as they confirm the potential we are
confident extends for the entire district at El Dorado Monserrat,
adding potential future resources to those known in the Main
Veins,” commented Estanislao Auriemma, CEO of Fredonia. “The new
interpretation of the target on La Herradura "hill", following the
Montana Tunnels model, notably increases the potential of the
entire district. We are looking forward to the laboratory results
for our drilling at Monserrat Oeste which will be reported shortly
and which we believe will confirm the presence of another
mineralized body further increasing the potential of the entire
area.”

The drill holes at La Herradura were drilled to
target both the roughly east west mineralised trend including the
central diatreme at La Herradura ‘hill’ and to expand the gold
anomalism identified in the historic drilling which extends over
1,100m to depths of >200m.
Fredonia remains positive about the results of
the drilling to date and the continued potential outlined at La
Herradura by these latest drilling results.
The mineralisation model proposed is similar to
the Montana Tunnels southwestern Montana bulk tonnage Au-Ag mine
centred on a diatreme hosted in a suite of volcanics. The principal
rock type in the diatreme is a matrix-rich breccia containing
fragments of contiguous volcanic wall rocks and intrusive rocks.
Sulphide mineralisation occurs as disseminations in the breccia
matrix, as well as in subordinate widely spaced, multidirectional
veinlets. The ore zone is overprinted by pervasive sericitic
alteration and weak kaolinization and silicification.
Drill holes have intercepted hydrothermal
breccias, veins and stockworks, hosted in a phreatomagmatic
breccias, felsic domes and dikes that intrude the andesite flows
which form the country rock.
Gold mineralisation is related to a quartz +
sericite alteration and minor bladed calcite and adularia,
interpreted as evidence of a boiling zone in an epithermal system.
The shallow and distal zones show a chlorite + hematite + pyrite
alteration, while in the deeper sections there are veins of platy
calcite + fluorite. Superimposed on the system is an alteration
halo of kaolinite + alunite and vuggy quartz, occurs in shallow and
medium-deep sectors.
The current drilling whilst of limited meters
has enhanced the project’s potential and confirmed the presence of
wide intersections of mineralised material with higher grade
inclusions. The system is interpreted to remain open in all
directions and Fredonia believes more drilling is warranted.
A recent geophysical program (IP / Res) over the
La Herradura area indicates three new anomalies, extending the
system 600m to the west. In a district scale context La Herradura
lies in a roughly east west mineralisation trend which extends
eastwards to the Beethoven project, (on strike with Cerro
Vanguardia – Anglo Gold Ashanti) and westward to Fredonia’s
recently identified Pamala prospect.
Follow-up drilling in planned to commence Q1
2022 with the objective of further delineating the Au-Ag
mineralisation.
Quality Assurance/Quality
Control:
All core samples were submitted to Alex Stewart
Laboratory in San Julián for preparation, and transported by the
Laboratory to their main Laboratory Mendoza for the analysis. All
samples were analyzed for Au and Ag by fire assay/ AA finish 50 g,
plus a 39-element ICP-AR finish. Fredonia followed industry
standard guidelines for the work with a quality assurance/quality
control (QA/QC) program. Blanks and reference material of both high
grade/ low grade gold and silver standards were included with all
sample shipments to the Laboratory. ‘Field duplicates’ were made
from coarse reject material supplied by the principle Laboratory
for re-analysis as well as checking by a second certified
laboratory. Fredonia detected no significant QA/QC issues during
review of the data so far received. QA/QC assessment is
ongoing.
Marc J. Sale, Qualified Person, is a competent
person as defined by Canadian National Instrument 43-101, has read
and approved the technical contents of this release.
Technical Information
The technical contents of this press release have been reviewed
and approved by Marc J. Sale FAustIMM MAIG, a qualified person
pursuant to National Instrument 43-101 (“NI 43-101”). Mr. Sale is
qualified as a geologist with a technical background in mineral
exploration, including specifically gold and silver deposits.
ACA Howe’s Senior Associate Geologist, Marc J. Sale (QP), was
onsite for several days during Fredonia’s drilling in March 2018.
During this period, the drilling, sampling and security procedures
were witnessed and all were considered to be in line with industry
best practices. Drill core and sampled drill core were under the
continuous supervision by Fredonia. At the drill site a dedicated
assistant supervised drill core quality control, including
observing the removal from the core barrel, placement in the core
box, cleaning and correct insertion of the ‘core block’. There were
very frequent visits by geological staff during both day and night
drill shifts. Drill core, having been correctly orientated, was
cleaned and then in sealed wooden boxes before being transported to
the core logging area; a secure area removed for the main camp and
cordoned off with restricted access signs. Once core was logged and
‘marked’ up for sampling it was moved to the core cutting shed
which was kept locked when not operational. The half core in the
designated sample intervals was bagged, labelled and sealed. Prior
to transport to the laboratory all samples were kept in a secure
shed which was locked by the supervising geologist. Samples were
periodically transported by 4WD to the laboratory by Fredonia field
staff in secured hessian bags. The bags were checked for any signs
of damage when delivered before being handed into the custody of
the laboratory for sample preparation.
All drill core sampled by Fredonia, as well as verification
samples collected by Marc J. Sale (QP), were assayed by Alex
Stewart Laboratories in Mendoza. Samples were prepared in their
laboratory in San Julian some 155 km east-southeast of the EDM
property. Alex Stewart Laboratories is accredited to ISO standards
and has ISO 9001:2015 and ISO 14001:2015 certification for its
facility in Mendoza where all analyses were conducted. Alex Stewart
Laboratories is independent of Fredonia and acts as a service
provider as and when required. On receipt at the laboratory the
samples were logged in and ascribed a unique bar code. Samples were
then weighed and dried at 40°C, before being crushed to #10 mesh.
The bulk of the coarse sample was stored. The ~600 g sub-sample was
pulverised until 95% passed #140 mesh. Gold was assayed by Fire
Assay using a precise 50g charge, fused at 1050°C with flux, then
smelted and refined to produce a lead alloy. This was followed by
cupellation of the lead alloy, before dissolving in Aqua Regia from
which 10 ml was analysed by an Atomic Absorption Spectrometer to
determine the gold assay value. For silver assays the process is
similar, although the finish is by 10 ml being dissolved in HNO3
but also with an AA spectrometer finish. All samples were also
analysed by ICP for a suite of 39 elements.
QA/QC comprised of blanks and certified reference material (CRM)
being inserted into the sample stream, on average 10% of material
analysed was either a blank or CRM. Blanks were derived from a
mixture of laboratory sources and white quartz of unknown origin.
CRM was bought from a certified source – GeoLabs of Australia. All
blanks were reported in assay as being below detection limit for
both gold and silver. This indicates that contamination is not
present in any significant quantity. Analysis of CRM samples
indicates that the laboratory accuracy is generally acceptable,
with 95% CRM analyses within three standard deviations of the
mean.
As well as the QA/QC reported above, for the 2018 drilling
programme, 31 pulps and coarse rejects were re-assayed by Alex
Stewart Laboratories (ASL). In addition, a 50% split of the 31
coarse rejects were sent to Bureau Veritas Minerals (ACME Labs) in
Canada for further re-analysis. Comparison of results with the
original assays for both gold and silver shows a strong positive
correlation, providing confidence in the original assays.
About the Project
The Deseado massif is a tectonic block which comprises Jurassic
and Cretaceous volcanic outpouring, containing two important
geological groups: the Bajo Pobre and Chon Aike both of which are
prospective for low sulphidation epithermal style gold-silver
mineralisation, such as being exploited at Anglo Gold Ashanti’s
Cerro Vanguardia gold – silver mine located approximately 17 kms
from Fredonia’s properties.
The Company’s property contains other prospects which are
interpreted as prospective on the basis of drilling so far
conducted, and several other prospects with identified structures
containing significant gold-silver values in rock chip, channel and
drill samples.
