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.

“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
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).

Figure 1: Schematic model of mineralization within a typical tourmaline breccia pipe (adapted from Kirwin, 2019) is available at https://www.globenewswire.com/NewsRoom/AttachmentNg/60d5e329-e92d-4df0-aef2-8f25353a34d7. Tourmaline breccia pipes can extend over 2 or 3 km in depth. Mineralization within a breccia pipe is typically uniform throughout the top of the breccias (the ‘roof’) while at greater depths the breccia pipe widens with higher-grade mineralization becoming focused along the margins and ends (‘lobes’) in intrusion-related breccia pipes. The drill holes at SFdLA are interpreted to have intersected the roof and lobes of the breccia pipe, while recent holes SFDH-014, SFDH-015 and SFDH-020 are interpreted to have intersected the top of the breccia ‘core’ zone.
