Turmalina Metals Corp. announced the discovery of a high-grade gold vein system and a new copper-gold mineralized breccia pipe following the successful completion of 2,984 m of diamond drilling at the Company's 403 km2San Francisco project located in the prolific mining province of San Juan, Argentina (the "Project" or "San Francisco"). The recently completed 22-hole program included maiden drilling at 5 targets over the extensive project area.

Initial mapping and sampling at Veta Rica defined a low-sulfidation epithermal quartz vein, 1 to 6 m wide, outcropping over 300 meters of strike length that returned rock chip assays of up to 56 g/t Au. SFDH-078 from 36.6 m. Including 0.5 m @28.6 g/t Au from 36.6 m. And 0.45 m @ 14.12 g/t Au from 38.85 m. 8.75 m @ 3.5 g/t Au; SFDH-079 from 42 m. Including 6.0 m @ 4.6 g/t Aufrom 42 m. Including 1.18 m @ 17.9 g/t Au from 42 m. Follow up mapping has defined a series of epithermal veins extending for up to 1.5 km, both along strike, and parallel with, the drilled Veta Rica vein, with assay results pending. Mapping is ongoing and the system remains open along strike and at depth.

This mineralization is similar to that of several epithermal mines located along-strike of project, including Austral Gold's Casposo Mine, located 70 km to the south. Ony two holes have been drilled into this new discovery, and both holes have returned grades of over 17 g/t Au. Ongoing surface work has already extended the strike length of the vein system from 300 m to over 1.5 km.

Veta Rica discovery hole drill core being examined by CEO James Rogers. Three other prospects were tested during the program. The Turmalina technical team is currently in the field continuing surface work on the new Veta Rica discovery along with other nearby targets.

team is also currently modelling the Ethan Breccia discovery with an aim of designing follow-up drill holes in this large breccia system. The project benefits from well-developed infrastructure and is 130 km northeast of the regional capital San Juan. Results from the drilling on this project can be found in Company News releases with the following dates: March 23, August 28, October 5 & December 7, 2020 and January 25, March 30, June 8 & August 30, 2021.

The projects are characterized by open high-grade mineralization on established mining licenses that present compelling drill targets. The principal 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 .

At San Francisco, drill core is collected at the drill site and transported by vehicle to the Turmalina core logging facility in Villa Nueva where recovery measurements are taken b efore the core is photographed and geologically logged. For drill core samples are inserted into each 70-sample dispatch: 1 blank sample, 5 commercially-prepared standards, 1 core duplicate sample and 1 control sample from the SF mine. The assay results for the QA/QC samples are checked and verified by the project geologically logged.
