Turmalina Metals Corp. announced the commencement of the 2022 field program at the San Francisco Project in San Juan, Argentina. Drilling by the Company at the Project has already established the SFdLA breccia pipe as one of the highest-grade tourmaline copper-gold-silver breccias ever discovered.

As tourmaline breccia pipes occur in clusters the Company expanded the project in 2021 from 3,400 ha to 34,600 ha. Initial exploration of this expanded area has returned highly encouraging results at multiple breccia and vein systems. The 2022 field program is focused on defining and drill testing new targets in the expanded project area, with detailed mapping and sampling currently underway at high-priority drill targets, including several recently discovered intrusion-related gold systems: Ethan: an 80 m wide tourmaline breccia pipe with widespread copper oxides that has returned rock chip values of up to 5.2 % Cu, 3.3 g/t Au and 23 g/t Ag: similar or better size, grades and geology as at the surface of the SFdLA breccia pipe. Amarilla: a 750 m long quartz vein system, up to 6 meters wide, composed of saccharoidal quartz and secondary Pb carbonates that has returned rock chip results up to 3.5 g/t Au, 565 g/t Ag and 30 % Pb.

Amarilla is similar to several economic vein systems that have been mined along the regional belt. Irma: an intrusion-related Au-Ag-Cu system exposed over a 550m strike length, with sheeted horizontal quartz veins that returned assays of 1 to 6 g/t Au, 150 to 524 g/t Ag and 0.5 to 4.5% Cu (maximum 17.3 % Cu). Tres Magos South: an intrusion-related Au-Ag system with a 100m wide zone of horizontal sheeted quartz veins hosted in sericite-altered granodiorite.

Initial assays have returned grades of 3 to 8 g/t Au, up to 367 g/t Ag and up to 17 % Pb. In addition to current sampling at the above projects, detailed work will commence in the next few weeks at several previously reported projects including the 30 to 70 m wide Los Pirquineros breccia pipes (rockchips of 0.7 to 3.5 g/t Au, 10 to 145 g/t Ag and 0.2 to 1.2 % Cu), the 100m wide NW Santa Barbara breccia pipe (1 to 16 % Cu, 3 to 1650 g/t Ag and 0.1 to 0.3 g/t Au) and the 20 to 200 m wide Santa Barbara tourmaline breccia pipes (up to 3.3 g/t Au, 11 g/t Ag and 0.6 % Cu). Quartz-tourmaline- sulphide vein systems scheduled for detailed follow up include the 1.6 km long and 8 m wide Miranda vein system (up to 6.0 % Cu, 3.9 g/t Au and 593 g/t Ag in rock chips) and the 1km long Tocota vein system (rockchips of 1.0 to 9.2 g/t Au, 1 to 38 g/t Ag and 0.1 to 0.5 % Cu).

For reference, sampling of the weathered `leached zone' above the high-grade SFdLA breccia pipe has average values of <0.1 to 0.3 % Cu, 0.1 to 5 g/t Au and 5 to 50 g/t Ag. Field work at the company's Chanape copper-gold project in Peru has identified over 50 tourmaline breccias with at least six returning Cu-Au-Ag grades similar or better than grades at SFdLA thus far (rock chips up to 35 g/t Au and 89 g/t Ag in oxidised samples). Limited drilling of several breccias by previous owners in 2008 intersected board zones of high-grade Cu-Au-Ag breccia that have not been followed up including 71m at 1.99 % Cu, 0.84 g/t Au & 43 g/t Ag and 55m @ 2.3 % Cu, 0.58 g/t Au & 42 g/t Ag.

Drilling of adjacent porphyry or intrusion-hosted systems intersected wide zones of moderate copper mineralisation typical of primary (hypogene') porphyry mineralisation in Peru (284m @ 0.38% Cu and 282 ppm Mo) with the potential for overlying high-grade supergene enrichment zones and adjacent skarns. The Company expects to receive the final permit to drill at Chanape in the next 2-3 months, and field work will recommence at the end of the summer wet season.
