Turmalina Commences Aggressive 2023 Exploration Program

VANCOUVER, March 02, 2023 - Turmalina Metals Corp. ("Turmalina", or the "Company"; TBX-TSXV, TBXXF-OTCQX, 3RI-FSE) is pleased to provide an update on exploration plans for the 2023 exploration season at the Chanape and San Francisco de los Andes Projects ("Chanape", and "San Francisco", collectively the "Projects"), located 87km east of Lima, Peru and the prolific San Juan Province of Argentina respectively.

Positive results from drilling at Chanape and surface works at San Francisco have guided the planning of the next steps of exploration at these two projects for the Company. With seven priority targets identified at San Francisco and Chanape delivering high grades from the Company's 2022 drill program the Company is well posed to carry out an aggressive exploration program in 2023 following its recently-completed financing.

Chanape Project Highlights:

• Multiple mineralized breccias identified with preliminary drill testing.
• Only 5 of over 50 known mineralised breccias drill tested to date.
• Select highlights of recent drilling in Table 1 include results such as:
  • CHT-DDH-038: 39.6 m of 3.10% CuEq from 60 m
  • CHT-DDH-041: 48.05 m of 3.80% CuEq from 165.7 m
    

San Francisco Project Highlights:

• Land position expanded to 40,340 ha (403.4 sq km): one of the largest exploration land positions in San Juan.
• Seven new high-priority targets identified.
• Recent work includes 8,406 soil samples, 1,333 m of channel samples and 7386 rock chip samples.
• Highlight results from recent work include (see Company news release of December 7, 2022):
  • Tres Magos
    • 18 rock chip samples and 50 channel samples over 1 g/t Au, including 12m @ 7.1 g/t Au and 115 g/t Ag, 3.7m @ 1.71 g/t Au and 102 g/t Ag, 3.5m @ 1.6 g/t Au and 30 g/t Ag and 3m @ 3.2 g/t Au and 186 g/t Ag;
  • Veta Amarilla
    • 5 rock chip samples over 1 g/t Au and 8 rock chip samples over 100 g/t Ag;
  • Breccia Ethan
    • 4 rock chip samples over 1 g/t Au and 12 rock chip samples over 1% Cu;
  • Veta Rica
    • 18 rock chip samples over 1 g/t Au, with up to 56 g/t Au.
• Highlight results from previous Turmalina drilling on the San Francisco de Los Andes Breccia Pipe are summarized in Table 3 and include results such as:
  • SFDH-012: 109 m of 5.49% CuEq from 12 m in oxides
  • SFDH-039: 72.3 m of 4.85% CuEq from 397.7 m in sulphides

Mr James Rogers, Chief Executive Officer, states:

"With excellent results from the 2022 exploration efforts in hand for the Chanape and San Francisco Projects our team is excited to be financed and ready to advance the multiple targets identified at San Francisco in Argentina and carry on drilling operations at Chanape. Both projects are continuing to deliver fantastic high-grade results and expanding the drill targets is a critical next step in our path of advancing these projects."

At San Francisco the Company is preparing for a program of approximately 12,000 metres of everse Circulation drilling to test seven new high-priority targets generated from the diligent work of the exploration team over 2022. These targets have not yet been drill tested by previous operators. The work program will also include establishing a local trail network, trenching surface showings and further surface works to aid and assist the targeted drilling. The Company is actively preparing and mobilizing equipment to support the drill program and expects to commence drilling in late March.

At Chanape the exploration team is awaiting approval of an enlarged permit area for drilling that will enable drill-testing priority Cu-Au-Ag breccias outside of those tested in the initial phase of drilling. A diamond drilling program is expected to commence in May and will include additional definition of the mineralized breccias tested to date as well as new, previously untested targets.

The Chanape Project

The 677 ha Chanape copper-gold project is located approximately 87 km east of Lima, Peru and is accessed via 24km of unpaved road from Turmalina's operational centre in the town of San Damian. The Chanape project is characterised by multiple tourmaline gold-silver-copper (Au-Ag-Cu) breccia pipes, with over fifty identified to date. These breccia pipes are clustered around a large, mineralised copper-molybdenum intrusion. Historical drill holes have confirmed mineralisation on breccia pipes and recent surface geological mapping have added new mineralised bodies for follow-up.

Table 1 - Highlight Results of the 2,257m Chanape total Phase 1 Program carried out in 2022 (see news releases dated January 10, 2023, December 14, 2022, November 15, 2022).

*Intersections are not true widths and additional drilling and geological modelling of the mineralised zones in the breccia pipes is required to determine the true widths of the drill hole intersections. Intersections are selected based on a 0.5 g/t Au or 0.3% Cu cut-off grade, a minimum downhole length of 2m and a maximum waste inclusion of 2 consecutive meters. Equivalent gold (AuEq) and equivalent copper (CuEq) values are calculated assuming 100% recovery using USD$ 1770 oz Au, $23 oz Ag and $8300/t Cu (~$3.8/lb).

Figure 1 - Chanape Project - Geology and Prospects Drilled in 2022. The Project is characterised by over 50 tourmaline breccia pipes (purple) and multiple epithermal vein systems (red).

Turmalina's work to date has been focused on interpreting historic work while mapping and sampling over 50 documented tourmaline breccias and epithermal veins at the project and drill-testing the best targets. A phreato-magmatic breccia, measuring 700 m by 200 meters has also been identified as a potential target for bulk tonnage mineralisation, with gold anomalism coincident with a geophysical anomaly (IP).

Turmalina has an option to acquire 100% of the Chanape Project.

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. Limited shallow drilling and channel sampling at the SFDLA Breccia returned spectacular grades of 2-12 g/t gold and 0.3 to 3% copper over 20-40 m intervals. The mineralogy and geological setting indicates that only the top of the breccia pipe has been exposed.

The land position at San Francisco was expanded in 2022 and now includes multiple mineralised targets including 60 breccias, intrusion-related gold and epithermal vein-type targets detailed in table 2.

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 the SFDLA project.
