Turmalina Metals Corp. provide an update on ongoing surface work at the Company?s 403 km2San Francisco project located in the prolific mining province of San Juan, Argentina (the ?Project? or ?San Francisco?).

Following the discovery of the high-grade epithermal gold vein system at Veta Rica exploration team has identified numerous new mineralized targets in the vicinity of Veta Rica and as far as 12 km north - highlighting the extent and scale of mineralization at this exciting new epithermal camp. Heavy equipment has now been mobilized to prepare drilling platforms, access roads and transect target mineralized structures. Teams have identified three new vein systems in the vicinity of Veta Rica namely: Veta Blanca, Veta 21 and Mosquete.

These are new areas in addition to the Destino and Machete veins and the Tiki-Tiki Breccia that were discovered after drilling at the Veta Rica discovery and were described in the news release of 15 November 2023. The historic Tocota vein area has also been mapped and sampled with encouraging results: Tocota is located 12 km to the north of Veta Rica and represents a northern extension of mineralized veins and structures in this mineralized belt. The seven vein systems that are currently exploring are: Veta Rica (initial epithermal discovery): Recent mapping has traced the Veta Rica epithermal vein for over 700 m on surface with surface widths of 1 to 6 m: Surface rock chip gold assays are typically between 0.9 and 2.7 g/t Au but with higher grade zones of up to 56.6 g/t Au.

This mapping has also identified multiple mineralized veins adjacent to, and parallel with, the Veta Rica vein with similar average rock chip grades (typically 0.45 to 4 g/t Au). Detailed sampling is underway to identify potential high-grade zones in these newly discovered veins. Initial drilling in 2023 at Veta Rica returned: 4.4 m @ 6.4 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 Au from 42 m. Including 1.18 m @ 17.9 g/t Au from 42 m. Veta Blanca: At Veta Blanca an epithermal vein system has been mapped and sampled in an area 300 meters wide by 1.2km long.

Vein thickness reach locally up to 3 meters with typical epithermal textures such as lattice textures and crustiform/colloform banding. Limited grab samples to date have a maximum value of 1.48 g/t Au, with anomalous Pb and Zn ? features typical of intermediate sulphidation epithermal systems. An access road is currently being prepared to facilitate detailed mapping and sampling, which will guide an initial drill program.

Veta 21: Additional sampling at the Veta 21 vein, which had returned initial rock chip samples of up 21.1 g/t Au, has confirmed presence of high-grade gold, with new rock chip samples returning assays of up to 5.2, 10.9 and 44.2 g/t Au. The Veta 21 quartz-tourmaline vein, and adjacent sericite alteration, can be traced over a 1.2km strike length, and reaches up to 3 meters in vein thickness. An access road is currently being constructed to provide better exposures of the vein, with a detailed mapping and sampling program planned to guide initial drilling.

Mosquete Epithermal mineralization at Veta Rica is associated with a strong halo of promoted lead. Follow up investigation of a 300 by 700m lead soil anomaly at Mosquete has identified multiple epithermal quartz veins, up to 3 m wide and exposed over a 200m strike length, that have returned initial rock chip gold values of up to 5.6 g/t Au. Destino: Four parallel epithermal quartz veins, and two adjacent breccias, discovered in 2023, are located 3 km northwest of Veta Rica.

Initial rock chip sampling (56 samples) of the veins, each with over 200 m of strike length, returned similar gold grades to Veta Rica, with 10 samples over 1 g/t Au, up to a maximum of 6.1 g/t Au. Tiki-Tiki Breccia: The Tiki-Tiki tourmaline-quartz breccia pipe was discovered in 2023 in the southern portion of the Destino target area. 34 rock chip samples taken from the 200 by 150 m wide breccia pipe returned four samples over 1 g/t, up to a maximum of 32.8 g/t Au, 227 g/t Ag and 0.9% Pb.

Tocota Veins: Tocota is located 12 km north of Veta Rica, with two east-west trending gold-arsenic vein systems that were mined in the 1940?s. The Tocota veins are hosted in the sediments - siltstones and sandstones of the Carboniferous Agua Negra Formation, which is intruded by the Tocota Batolith. The veins are surrounded by a 2 to 6 meter wide sericite alteration halo, with abundant quartz veinlets. Channel sampling of old mine workings has confirmed strong gold mineralization, with channel samples of up to 5 to 27 g/t Au.
