Vancouver, BC - December 7, 2020 - Turmalina Metals Corp. (Turmalina or the Company) (TSXV:TBX - WKN:A2PVJL) 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 (at) 7.9 g/t Au, 60 g/t Ag & 0.14% Cu (8.8 g/t AuEq) from surface (SFDH-030)
o including 6m (at) 23.7 g/t Au, 142 g/t Ag & 0.04% Cu (25 g/t AuEq) from 3m
· 21m (at) 3.4 g/t Au, 25 g/t Ag & 0.11% Cu (3.8 g/t AuEq) from surface (SFDH-031)
o including 8m (at) 5.8 g/t Au, 17 g/t Ag & 0.22% Cu (6.2 g/t AuEq) from 5m
o and 14m (at) 2.2 g/t Au, 72 g/t Ag and 0.26% Cu (3.3 g/t AuEq) from 26m
o and 17m (at) 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 (at) 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 (at) 0.44% Cu, 0.03 g/t Au and 7 g/t Ag from 72m (SFDH-026; including 18m (at) 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 (at) 0.24 g/t Au in SFDH 027 and 4m (at) 0.35 g/t in SFDH028) but no economic intersections.

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-molybdenum 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 molybdenum discoveries who are highly experienced in this deposit style. Our projects are characterised by open high-grade mineralisation 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 Corporations 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.

Figure 1 - Schematic model of mineralization within a typical tourmaline breccia pipe (adapted from Kirwin, 2019). 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. The drill holes at SFdLA are interpreted to have intersected the roof and lobes of the breccia pipe, while recent holes SFDH-014, SFDH-015 and SFDH-020 are interpreted to have intersected the top of the breccia core zone.
Figure 2 - Interpretation of mineralization at level 2700RL at the SFdLA breccia pipe. 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.
