Turmalina Metals Corp. (“
Turmalina”, or the
“
Company”; TBX-TSXV, TBXXF-OTCQX) is pleased to
announce the drilling program at the San Francisco project
(“
San Francisco” or the
“Project”) has continued to
intersect broad intervals of gold-silver-copper mineralization at
the San Francisco de Los Andes (“
SFdLA”) breccia
pipe, as well as broad intervals of copper mineralization in the
Chorrillos breccia pipe.
Phase 2 drilling at the SFdLA breccia has
identified strong, near-surface oxide gold mineralization at the
top of the breccia pipe, with recent drill holes designed to test
this oxide zone intercepting:
-
22m @ 7.9
g/t Au, 60 g/t Ag &
0.14%
Cu (8.8 g/t AuEq) from surface (SFDH-030)
○ including
6m @ 23.7
g/t Au, 142 g/t Ag &
0.04% Cu (25 g/t AuEq)
from 3m
-
21m @
3.4 g/t Au, 25
g/t Ag & 0.11%
Cu (3.8 g/t AuEq) from surface (SFDH-031)
○ including
8m @ 5.8
g/t Au, 17 g/t Ag &
0.22% Cu (6.2 g/t AuEq)
from 5m
○ and 14m @ 2.2
g/t Au, 72 g/t Ag and 0.26% Cu (3.3 g/t AuEq) from 26m
○ and 17m @ 2.2
g/t Au, 58 g/t Ag and 1.0 % Cu (4.0 g/t AuEq) from 51m
Deeper drilling beneath the oxide zone has
focused on testing the western half of the breccia pipe,
intersecting primary sulphide gold-silver-copper mineralization
and, in the case of SFDH-029, defining a new westward extension to
the breccia pipe that remains open in all directions (i.e
29m @ 2.4
g/t Au, 82 g/t Ag and
0.44% Cu (4.1 g/t AuEq) from 65m).
Turmalina is also pleased to announce that
first-pass drilling of other breccia pipes on the property has
returned broad zones of copper mineralization at the 200m diameter
Chorrillos breccia pipe, including 59m @ 0.44% Cu, 0.03 g/t
Au and 7 g/t Ag from 72m (SFDH-026; including
18m @
0.80% Cu from 74m).
Mineralization at Chorrillos appears to be a
copper-dominated assemblage typically found in the deeper and wider
parts of tourmaline breccia pipes, and samples from a second hole
at Chorrillos are currently being prepared for dispatch and
assay.
Further intersections are reported in Table 1:
Intersections are not true widths and additional drilling and
geological modelling of the mineralised zones in the breccia pipes
is required to make a determination of the true widths of the drill
hole intersections. Drill hole coordinates are shown in Table
2.
Dr. Rohan Wolfe, Chief Executive Officer,
states:
|
“The intersection of nearly ounce-per-ton gold grades in the first
holes to directly target the oxide zone at the SDFdLA is extremely
encouraging. These high gold grades are within metres of the
surface and part of a 20 meter thick blanket of high-grade oxide
gold that our exploration team is currently modelling. Deeper
drilling at SFdLA has focused on defining the shape of the western
half of the breccia pipe, with the exciting discovery of a new
westward extension at depth that remains completely open. The broad
zones of copper mineralization intersected at the large Chorillos
breccia pipe validates our model that the project contains multiple
mineralized breccia pipes, and we look forward to keeping the
market informed as we continue to drill and explore at this
remarkable project.” |
|
Currently two drill rigs are focused on testing
the deeper parts of the SFdLA breccia pipe beneath current
drilling. To date 27 Phase 2 holes have been completed for a total
of 6670 m. Nineteen of these holes test the SFdLA breccia pipe
while nine holes test 4 breccia targets out of over 60 identified
during the summer field program. The first three Phase 2 holes were
reported on August 28th, six holes were reported on October 5th,
ten holes are reported in this release and samples from the
remaining seven holes have been dispatched for assay.
In addition to the above holes at the SFdLA and
Chorrillos breccia pipes the Company has received assay results for
two holes drilled at the Colorada breccia pipe, located 4 km to the
northwest of SFdLA. Drill holes SFDH-027 and SFDH-028 intersected
strongly epidote-sericite-tourmaline altered sediments cut by
pyrite-quartz-tourmaline-chalcopyrite tourmaline breccias with
elevated gold, silver and copper (i.e. 6m @ 0.24 g/t Au in SFDH 027
and 4m @ 0.35 g/t in SFDH028) but no economic intersections.
About the San Francisco
Project
The 3404 ha San Francisco project is located in
San Juan, Argentina. The project area contains over 60 tourmaline
breccia occurrences, several of which have supported small-scale
mining. The Company is focused on mapping and sampling the breccias
in the project area, and drill testing the highest priority
targets.
To minimize the risk of COVID-19 transmission to
our team and the community, the Company has applied rigorous
protocols throughout the program. These protocols have been
approved by the authorities of the province of San Juan, and both
Turmalina Metals and local subsidiary Aurora Mining maintain close
contact with the local authorities in order to comply with all
regulations. These procedures include social distancing, improved
hygiene, health screening of all staff and contractors, longer
rosters at our remote field camp and an onsite medical professional
to monitor health and ensure procedures are followed.
The protocols put in place by the Company and
local authorities have helped successfully prevent any cases of
COVID-19, to date, at the Project.
Other Projects
Turmalina has entered into agreements to explore
two projects located in Peru: the Chanape copper-gold project
located in Lima District (the ‘Chanape
Project’) and the Turmalina copper-gold molybdenum
project located in Piura District (the ‘Turmalina
Project’). Both projects contain clusters of mineralized
tourmaline breccias and are undergoing permitting or social
consultation prior to the commencement of exploration.

Statements
About Turmalina Metals and the San
Francisco Project: Turmalina Metals is a TSXV-listed
exploration company focused on developing our portfolio of high
grade gold-copper-silver projects in South America. Our focus is on
tourmaline breccias, a deposit style overlooked by many explorers.
Turmalina Metals is led by a team responsible for multiple
gold-copper-silver discoveries who are highly experienced in this
deposit style. Our projects are characterised by open high-grade
mineralization on established mining licenses that present
compelling drill targets. The principle project held by Turmalina
is the San Francisco project in San Juan, Argentina. For further
information on the San Francisco Project, refer to the technical
report entitled “NI43-101 Technical Report San Francisco Copper
Gold Project, San Juan Province, Argentina” dated November 17, 2019
under the Corporation’s profile at www.sedar.com.
Sampling and Analytic
procedure: Turmalina Metals follows systematic sampling
and analytical protocols which exceed industry standards and are
summarized below.
All drill holes are HQ diameter diamond core
holes. Drill core is collected at the drill site and transported by
vehicle to the Turmalina core logging facility in Villa Nueva,
where recovery and RQD (Rock Quality Designation) measurements are
taken before the core is photographed and geologically logged. The
core is then cut in half with a diamond saw blade with half the
sample retained in the core box for future reference and the other
half placed into a pre-labelled plastic bag, sealed with a plastic
zip tie, and identified with a unique sample number. The core is
typically sampled over a 1 to 2 meter sample interval unless the
geologist determines the presence of an important geological
contact. The bagged samples are then stored in a secure area
pending shipment to the ALS sample preparation facility in Mendoza
where they are dried, crushed and pulverized. Following sample
preparation the prepared pulps are then sent to the ALS laboratory
in Lima for assay. The samples are then analyzed using a 50g aqua
regia digest and fire assay-AA finish analysis for gold and four
acid digestion with ICP-MS analysis for 53 other elements. Samples
with results that exceed maximum detection values for gold are
re-analyzed by fire assay with a gravimetric finish and other
elements of interest are re-analyzed using precise ore-grade ICP
analytical techniques. Turmalina Metals independently inserts
certified control standards, coarse field blanks, and duplicates
into the sample stream to monitor data quality. These standards are
inserted “blindly” to the laboratory in the sample sequence prior
to departure from the Turmalina Metals core storage facilities.

Schematic model of
mineralization within a typical
tourmaline breccia pipe (adapted from

available at
https://www.globenewswire.com/NewsRoom/AttachmentNg/b73841e7-35d6-43f7-a07b-1305342691ac. Tourmaline
breccia pipes can extend over 2 or 3 km in depth. Mineralization
within a breccia pipe is typically uniform throughout the top of
the breccias (the ‘roof’) while at greater depths the breccia pipe
widens with higher-grade mineralization becoming focused along the
margins and ends (‘lobes’) in intrusion-related breccia pipes.

Drilling at SFdLA is interpreted to have intersected the roof of
the breccia pipe, with deeper holes defining strongly mineralised
margins and lobes that surround the central core of the breccia
pipe. At shallow levels the western lobe remains open to the north
and northwest (red arrows), while holes SFDH-022, 23, 24 and 29
defined and discovered a deeper westward extension.

To date over 60 tourmaline breccias have been mapped in the project
area. Phase 2 drilling tests the San Francisco de Los Andes
(SFdLA), Chorrillos, Humilde, Solita and Colorada breccias.
Drilling at SFdLA has focused on the south-east corner of a
composite breccia body, with the north-west extension tested as a
part of Phase 2 drilling.

Previous drilling by the Company at SFdLA positioned drill rigs
outside the breccia, using inclined holes to test across the pipe.
This drill hole geometry left the top 20-30m of the breccia pipe
(the ‘oxide’ zone) under-represented. Drill holes SFDH-030 and
SFDH-031 tested this oxide zone in the western half of the breccia,
returning high gold grades from surface.

SFDH-029 is a step out from the southwest margin of the breccia
pipe, intersecting a new zone of mineralized breccia outside the
previously defined boundary (red shell in background). This new
extension remains open in all directions.
