VANCOUVER, British Columbia, Aug. 28, 2020 (GLOBE NEWSWIRE) — Turmalina Metals Corp. (“Turmalina”, or the “Company”; TBX-TSXV, TBXXF-OTCQX) is pleased to announce that the first three holes of our Phase Two (~5000 meter) drilling program at the San Francisco project (“San Francisco” or the “Project”) have intersected broad intervals of high-grade gold-silver-copper mineralisation at the San Francisco de Los Andes (“SFdLA”) breccia. Significant intersections are reported in Table 1 below, and include:
83m @ 4.4 g/t Au, 82 g/t Ag & 0.43% Cu (5.9 g/t AuEq) from 25m (SFDH-011)
• Including 41m @ 7.03 g/t Au, 91 g/t Ag & 0.51% Cu (8.76 g/t AuEq) from 27m
109m @ 4.94 g/t Au, 109 g/t Ag & 1.1% Cu (7.55 g/t AuEq) from 12m (SFDH-012)
• Including 27m @ 9.02 g/t Au, 94 g/t Ag & 1.08% Cu (11.4 g/t AuEq) from 31m
• Including 3m @ 13.8 g/t Au, 111 g/t Ag & 0.08% Cu (15.3 g/t AuEq) from 15m
• Including 6.7m @ 7.43 g/t Au, 58 g/t Ag & 0.15% Cu (8.35 g/t AuEq) from 65m
• Including 11m @ 5.59 g/t Au, 134 g/t Ag & 1.34% Cu (8.75 g/t AuEq) from 98m
74m @ 1.1 g/t Au, 48 g/t Ag & 0.41% Cu (2.2 g/t AuEq) from 88m (SFDH-013)
• And 13m @ 0.9 g/t Au, 51 g/t Ag & 0.54% Cu (2.1 g/t AuEq) from 179m
These high-grade intersections remain open both at depth and laterally. The breccia textures observed in the drill core confirm that the current intercepts are related to the very top of the breccia system. Mineralisation in the top of tourmaline breccias may have a different orientation to the orientation of the breccia pipe (such as forming flat-lying ‘ceiling’ zones): Should the above drill intersections be at an oblique angle to mineralisation then the true width of mineralisation will be less than the reported intersections. Further drilling and geological modelling is required to constrain the geometry of mineralisation within the SFdLA breccia.The current Phase Two drilling program tests for extensions to high-grade gold-copper-silver mineralisation encountered in the first phase of drilling completed by the Company in 2019, which included intersections of 36.9m @ 6.3 g/t Au, 122 g/t Ag & 0.88% Cu (8.7 g/t AuEq, SFDH-001) and 85.3m @ 4.4 g/t Au, 109 g/t Ag & 0.79% Cu (6.6 g/t AuEq, SFDH-002; see Turmalina news release dated December 2, 2019 for full details).   Dr. Rohan Wolfe, Chief Executive Officer, states:“These outstanding initial results from our Phase 2 drilling indicate that high-grade mineralisation not only continues at depth at SFDLA but, as expected by our geological model, the SFdLA breccia pipe is starting to expand in width as we go deeper. Our 2019 campaign tested the SFdLA breccia pipe to a depth of 150 meters. These initial Phase 2 holes test the breccia pipe 30 to 150m below the 2019 drill holes and have returned similar high grades. Most tourmaline breccias are considered to be gold-rich at 1 g/t gold – so the broad intersections of gold-mineralised breccia returning 9-10 g/t gold at San Francisco are quite remarkable.“With high-grade mineralisation open at depth and laterally these are exciting times for Turmalina Metals and we look forward to keeping the market informed of new drilling results both at SFdLA and at satellite breccias that will be tested by the current program.“We have also been actively consolidating our holdings in the region with the recent acquisition of the neighboring Miranda properties. While our focus remains very much on San Francisco we have also strengthened our overall portfolio by acquiring the Chanape project in Peru, which contains a cluster of strongly gold-copper mineralised tourmaline breccias. We look forward to providing more detailed information on our acquisitions as we complete field work on these projects.”Drilling continues at the San Francisco Project, with 14 holes completed to date for a total of 3890m. Ten of these holes tested the SFdLA breccia pipe while four holes tested two breccia targets identified during the summer field program. The assays for the first three Phase 2 holes have been returned and are reported in this release, samples from a further three holes have been dispatched for assay at a commercial laboratory, and drill core from the remaining holes are currently being logged and sampled prior to dispatch for assay. The current drilling aims to extend mineralisation at SFdLA to greater depths as well as test for lateral extensions. In addition, the current program tests four of over sixty gold-copper mineralised breccias identified during the summer field program.Table 1: Phase 2 drill hole intersections from Turmalina’s drilling at the San Francisco de Los Andes breccia pipe.
