TURMALINA EXPANDS MINERALIZATION AT VETA RICA AND DISCOVERS NEW MINERALIZED ZONES

Turmalina Metals Corp. has released results from continued surface work at the company's 403-square-kilometre San Francisco project located in the prolific mining province of San Juan, Argentina. Following the recent discovery of the high-grade epithermal gold vein system at Veta Rica (see announcement dated October 10th, 2023) field work has focused on mapping and sampling the surrounding area. This surface work has discovered multiple mineralized veins in the immediate vicinity of Veta Rica and has also discovered two new zones of similar epithermal mineralization located approximately two and four kilometres northwest of Veta Rica: the Machete and Destino systems respectively.

Highlights of Veta Rica Target Area

Recent mapping has traced the Veta Rica epithermal vein for over 700 m on surface with surface widths of 1 to 6 m: Surface 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 (Figures 2, 3 & 4) with similar average grades (typically 0.45 to 4 g/t Au). Detailed sampling is underway to identify potential high-grade zones in these newly discovered veins.

Recently announced drill holes 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.

Highlights of Destino Target Area

A new system with at least four parallel epithermal quartz veins, and two adjacent breccias, located 3 km northwest of Veta Rica (Figure 2, 7, 8 & 9). Initial 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 (Figure 7).

In the southern portion of the Destino target area, 34 samples taken from a 100 by 130 m breccia pipe (the Tiki-Tiki breccia) returned four samples over 1 g/t, up to a maximum of 22 g/t Au, 227 g/t Ag and 0.9% Pb.

Highlights of Machete Vein zone

Located between Veta Rica and Destino, 2.7 km northwest of Veta Rica drilling, 3 rock chip samples taken from the Machete epithermal quartz vein returned grades of 1.1 to 2.7 g/t Au and 28 to 170 g/t Ag. Follow up sampling is underway (Figures 2 & 9).

Mr James Rogers, Chief Executive Officer, states: "After an exciting discovery at Veta Rica, the exploration team quickly went to work and we have now greatly expanded the area of known mineralization at Veta Rica, with the vein traced for over 700 m strike length and several parallel veins identified. Additionally, the team has already identified two new epithermal gold vein and breccia systems at Destino and Machete, with high-grade gold rock chip samples at surface. Turmalina is excited at the opportunity these nearby vein systems represent for our team to add value to our well positioned land package. With these recent discoveries it is becoming clear we have discovered a new epithermal district in this established gold belt, and we look forward to keeping the market informed of our exploration progress over the coming months in what is a very exciting time for the Company.

The Project area is located within a known epithermal gold belt. The nearest such epithermal gold system is located at Austral Gold's Casposo mine, 70 road kilometres south of the Veta Rica discovery. Casposo produced 283,000 oz of gold and 9.6 M oz of silver with average grades of 4.8 g/t Au and 183 g/t Ag between 2011 and 2015 and another 32,000 oz of gold and 3 M oz of silver between 2017 and 2019 before the mill was placed back into care and maintenance (2017-2019 Austral Gold Annual Reports). The historic epithermal district of Castano Viejo is located 20 km to the south of Veta Rica (Figure 1). Castano Viejo was operated by the National Lead Company S.A between 1956 and 1964, with an estimated reserve of 614,000t @7.4% Pb, 7.5% Zn, 0.15% Cu and 72 g/t Ag (Angeleli, 1984).

Drill planning and budgeting are underway for a 4,000 m diamond drilling program focussed on testing and expanding targets within the Destino and Veta Rica target areas. Surface works are continuing with crews focussed on additional surface sampling and mapping. After receiving results of the current sampling program, areas will be ranked and selected for trenching and construction of access roads prior to drilling.

Mapping and sampling have identified multiple mineralised veins at Veta Rica, Machete and Destino, and mapping is currently underway to define a potential new target in the top right of the map (21 g/t Au).

Figure 6: Examples of high-grade gold mineralisation in core samples and from an outcrop along strike from drilling at Veta Rica. Mineralisation is hosted in crystalline quartz (commonly brecciated) with intense sericite alteration and hematite-goethite-jarosite, formed by the weathering of sulphides.

Figure 8: Photos of an epithermal vein at Destino. Mineralization is hosted in epithermal quart veins (locally banded) and within intensely brecciated and sericite-altered granodiorite and diorite that hosted abundant hematite-goethite-jarosite veinlets.

Figure 9: Machete epithermal vein zone. The veins and gold mineralization are hosted in strongly sericite-altered granodiorite (a), with quartz veinlets (b) and portions brecciated with green/grey silica and iron oxides and jarosite. Float in the area includes samples of finely banded silica and iron oxide (d) and breccia with matrix of crystalline quartz (comb texture) with fragments of finally banded silica and iron oxides after sulphides (e), both textures typical of epithermal veins.

About The San Francisco Project

The 40,340 ha San Francisco project is located in the pro-mining province of San Juan, Argentina, a country where there are currently 12 operating mines, 5 in construction and 20 in pre-feasibility/feasibility stage. The project benefits from well-developed infrastructure and is 130 km northeast of the regional capital San Juan.

The San Francisco Project was assembled around, and includes, one of the highest-grade tourmaline breccias of the same name. The land position at San Francisco was expanded in 2022 and now includes multiple mineralized targets including more than 60 breccias, intrusion-related gold and epithermal vein-type targets.

Initial exploration efforts at San Francisco were focussed on breccia mineralization. Through the Company's extensive exploration work, led by Chico Azevedo, the project has greatly expanded into highly prospective areas containing a number of veins, intrusion-related, porphyry and breccia targets.

While the San Francisco breccia pipe remains one of the highest-grade tourmaline Cu-Au breccia pipes ever discovered (see select results in Table 1) the Company is most excited about the exploration potential for high-grade gold-silver and polymetallic vein types and other mineralization styles. The Veta Rica discovery exemplifies the style of epithermal mineralization commonly found in the district.

Turmalina has developed an operational centre in the town of Villa Nueva, where the local community welcomes new exploration efforts in the region.

Turmalina has several option agreements to acquire 100% of certain titles of the SFDLA project and a right to explore and exploit other titles from the government of San Juan.

On Behalf of the Company,

Mr James Rogers Chief Executive Officer and Director.
