In July the Company announced an expansion of the project area from 3,400 ha to 34,600 ha (see news release dated
Exploration of this newly acquired ground is a high priority, with current field work including an extensive soil sampling campaign and the detailed mapping and sampling of high-priority targets (Figures 1 and 2). Results from this initial exploration are highly encouraging with multiple breccia and vein systems returning significant assays (see news release dated
After receiving these early positive results, Turmalina has accelerated fieldwork with the collection of over 3200 soil samples and the detailed rock chip sampling of 16 prospects (more than 2000 rock chips, with 1500 assays returned to date). This work has discovered gold-silver-copper mineralization at several breccia and vein systems including:
- Los Pirquineros: Two adjacent 30 and 70m wide quartz-tourmaline-sulphide breccia pipes that have returned rock chip samples of 0.7 to 3.5 g/t Au, 10 to 145 g/t Ag and 0.2 to 1.2 % Cu
NW Santa Barbara : a 100m diameter tourmaline breccia pipe returning assays of 1 to 2 % Cu (maximum 16 % Cu), 3 to 15 g/t Ag (maximum 1650 g/t Ag) and 0.2 g/t Au.- Tocota 1: A quartz-tourmaline-sulphide vein system that extends for over 1 km in strike length with results of 1-5 g/t Au (maximum 9.2 g/t), 1-5 g/t Ag (maximum 38 g/t) and 0.1 to 0.5 % Cu.
- Ethan: a 100m diameter tourmaline breccia pipe that has returned rock chip values of up to 3.3 g.t Au, 23 g/t Ag and 5.2 % Cu
- The Miranda vein system: three parallel quartz-tourmaline-sulphide vein arrays up to 8 m wide with strike lengths of 900 to 1600m. Rock chips have returned up to 6.0 % Cu, 3.9 g/t Au and 593 g/t Ag.
Santa Barbara (IPEEM): Four 20 to 200 m wide tourmaline breccia pipes have returned rock chip assays of up to 3.3 g/t Au, 11 g/t Ag and 0.6 % Cu.- Amarilla Vein: a 900m long vein, up to 6 meters thick, composed of saccharoidal quartz and secondary Pb carbonates have returned rock chip results up to 1.8 g/t Au, 565 g and 26 % Pb.
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. Numerous other breccia and vein systems with artisanal workings and visible mineralisation have been mapped and sampled over the last 3 months, with assays pending.

“While the SFdLA breccia pipe is a fantastic high-grade discovery, it is only one breccia within a much-larger breccia field. Our exploration program over the last 3 months has focused on mapping and sampling the under-explored region around SFdLA, including the new acquisitions we announced in July. Covering such a large area with numerous targets takes time and requires systematic exploration. This has already discovered several sulphide-rich breccia systems similar to the SFdLA breccia pipe that have the potential to host strong mineralisation below the leached surface. The district is also known for epithermal and mesothermal gold vein systems that have supported numerous mining operations, and our team has identified several significant vein systems that are currently being followed up.
While this exploration is underway we have conducted a review and relogging exercise at SFdLA that has greatly increased our knowledge of this system and highlighted extensions for drill testing this summer.
The Company retains a strong cash position and is fully funded to conduct current exploration plans for 2022. We look forward to keeping the market informed as we explore and test these exciting new targets over the coming months.”
Drilling has paused while the exploration team focuses on mapping and sampling the expanded project area, with drilling of the highest-priority targets to start in summer. This break in drilling has allowed a detailed review of the geology, structure and mineralisation of the high-grade SFdLA breccia, which has identified new extensions that will be tested when drilling resumes.
