GR Silver Mining (TSXV: GRSL) (OTCQB: GRSLF) (FRANKFURT: GPE) – is pleased to report first exploration results for the Trampolín and Corta Pico vein systems, representing a set of N-S and NE-SW trending veins, located between the Plomosas and Loma Dorada vein systems. The Trampolín vein system can be considered the NE extension of the San Juan vein system, expanding the footprint of Au mineralization over 1,300 m to the NE (Figure 1). The results from Trampolín and Corta Pico confirm the presence of two Au-rich epithermal vein systems with the potential for higher-grade Au and Ag mineralization at depth. Mineralization at Trampolín and Corta Pico remains open along strike and down dip for future drilling.
Surface channel results from the Corta Pico vein system indicate the presence of high-grade Au-Ag mineralized veins:
- 4.1 m at 1.35 g/t Au and 6 g/t Ag (TPS21-CH-019), including:
0.4 m at 9.70 g/t Au and 44 g/t Ag
- 4.5 m at 2.50 g/t Au and 57 g/t Ag (TPS21-CH-006), including:
2.0 m at 4.45 g/t Au and 112 g/t Ag
First drill results received from the 2021 drilling program at Trampolín confirm an attractive wide Au mineralized system supported by nearby historical shallow workings:
- 12.0 m at 0.64 g/t Au and 2 g/t Ag (TPS21-01), including:
0.8 m at 3.38 g/t Au and 1 g/t Ag
- 7.2 m at 0.44 g/t Au and 6 g/t Ag (TPSP21-001), including:
1.2 m at 1.16 gt/ Au and 10 g/t Ag
GR Silver Mining President and CEO, Marcio Fonseca commented "The first drill results from the exploration program at Trampolín and Corta Pico show indications of an attractive epithermal vein system between Loma Dorada and the Plomosas Mine Area. The abundance of unexplored veins on surface, in parallel structures close to our existing resource areas, continues to underline the potential for multiple vein systems within the Plomosas Project. More importantly, these new discoveries serve to reinforce our exploration model and targeting strategy to continue to delineate multiple high-grade, precious metal veins with potential to add to future resource expansion. The Trampolín and Corta Pico targets are in the early stages of exploration and our team will continue to investigate their precious metal potential."
The Trampolín vein system can be considered the NE extension of the San Juan vein system, expanding the footprint of gold mineralization over 1,300 m to the NE (Figure 1). The Company has so far received assay results for two drill holes; one HQ diameter diamond drill hole of 183 m length (TPS21-01) testing the vein at 75 m depth, and a shorter 7.2 m BQ diameter, portable diamond drill hole (TPSP21-001) intercepting the near-surface expression of the same vein and testing its vertical continuity (Table 3). The vein is composed of a quartz-cemented crackle breccia with small amounts of galena and pyrite, hosted within an andesitic ignimbrite.
Significant results from the most recent drilling at Trampolín are shown in Table 1.
The Corta Pico vein system is located 800 m E of the Trampolín vein system (Figure 1). It consists of NE-SW to E-W trending veins. GR Silver Mining's surface channel sampling highlights the E-W trending vein at Corta Pico as highly prospective, with high-grade Au intervals of 2.0 m at 4.45 g/t Au and 112 g/t Ag, and 0.4 m at 9.70 g/t Au and 44 g/t Ag, outlining a Au and Ag-rich target for additional exploration.
Significant results from the channel sampling at Trampolín and Corta Pico are shown in Table 2.
