Phase Two Drilling Continues to Intersect Strong Gold-Silver-Copper Mineralisation at San Francisco de Los Andes

VANCOUVER, British Columbia, Oct. 05, 2020 (GLOBE NEWSWIRE) — Turmalina Metals Corp. (“Turmalina”, or the “Company”; TBX-TSXV, TBXXF-OTCQX) is pleased to announce that recent holes in our Phase Two drilling program at the San Francisco project (“San Francisco” or the “Project”) have intersected broad intervals of gold-silver-copper mineralization at the San Francisco de Los Andes (“SFdLA”) breccia.
Mineralization within tourmaline breccias tends to be most strongly focused on the roof, margins and ends (‘lobes’) of the breccia pipes (Figure 1). Drill hole SFDH-018 tested the width of the easternmost lobe of the SFdLA breccia pipe and intersected significant gold-silver-copper mineralization (Figure 2) that included:29m @ 4.2 g/t Au, 222 g/t Ag & 1.4% Cu (8.4 g/t AuEq) from 67m (SFDH-018)
°  Including 16m @ 5.3 g/t Au, 231 g/t Ag & 0.99% Cu (9.2 g/t AuEq) from 71m
Drill holes SFDH-014, SFDH-015 and SFDH-020 tested the centre of the SFdLA breccia and intersected a matrix-supported breccia typical of the core of a tourmaline breccia pipe (Figures 3 to 5), with intercepts that include:12m @ 2.0 g/t Au, 35 g/t Ag & 0.39% Cu (2.8 g/t AuEq) from 73m (SFDH-014)
°  And 40m @ 1.3 g/t Au, 83 g/t Ag & 0.43% Cu (2.6 g/t AuEq) from 104m
26m @ 1.2 g/t Au, 40 g/t Ag & 0.44% Cu (2.2 g/t AuEq) from 75m (SFDH-015)
°  And 17m @ 0.83 g/t Au, 12 g/t Ag & 0.42% Cu (1.4 g/t AuEq) from 136m
19m @ 0.8 g/t Au, 118 g/t Ag & 0.38% Cu (2.6 g/t AuEq) from 93m (SFDH-020)
°  And 9m @ 0.96 g/t Au, 40 g/t Ag & 0.37% Cu (1.8 g/t AuEq) from 136m
°  And 11m @ 0.57 g/t Au, 22 g/t Ag & 0.13% Cu (0.9 g/t AuEq) from 174m
°  And 1.2m @ 6.44 g/t Au, 17 g/t Ag & 0.32% Cu (7.0 g/t AuEq) from 200m
Three recently completed drill holes tested the westernmost lobe of the SFdLA breccia pipe, and samples from these holes have been dispatched for analysis. Further intersections are reported in Table 1: Intersections are not true widths and further drilling and geological modelling of the mineralised zones is required to make a determination of the true widths of the drill hole intersections. Drill hole coordinates are shown in Table 2.Dr. Rohan Wolfe, Chief Executive Officer, states: “It’s most encouraging to see the SFdLA breccia pipe widen and develop the classic tourmaline breccia geometry – just as expected by our geological model. High-grade mineralization is focused in well-defined lobes located at the margins of the breccia pipe and remain open at depth and laterally: these lobes are now the target of our ongoing drilling program, and we look forward to keeping the market informed as we continue to drill and explore this remarkable system.”To date 17 Phase 2 holes have been completed for a total of 4855m. Eleven of these holes test the SFdLA breccia pipe while six holes test three breccia targets identified during the summer field program. The assays for the first three Phase 2 holes were reported on August 28th, six holes are reported in this release, samples from a further four holes have been dispatched for assay, and drill core from the remaining holes are currently being logged and sampled prior to dispatch for assay.In addition to the above holes at the SFdLA breccia pipe the Company has received assay results for two holes drilled at the Humilde breccia pipe, located 2 km to the northwest of SFdLA. Drill holes SFDH-017 and SFDH-019 intersected strongly sericite-altered and pyrite-rich tourmaline breccia (Figure 6) with elevated gold, silver and copper (i.e. 1m @ 1.3 g/t Au, 6.8 g/t Ag and 0.17 % Cu from 47m; SFDH-019) but no economic intersections. Alteration at Humilde is similar to alteration zones found above and adjacent to mineralised breccias pipes and the drilling results are being reviewed by our technical staff in order to incorporate these findings into our geological model. Regional drilling is now focused on the Colorada, Solita and Chorrillos breccias (Figure 7).About the San Francisco Project
