High Grade Mineralization Extends Zone To South At La Parrilla Sliver Mine Complex

TORONTO - Silver Storm Mining Ltd. reported on the Phase 1 diamond drilling program at La Parrilla Silver Mine Complex, located in Durango Mexico. Results from the four holes within this release are from the Quebradillas mine. Hole Q-23-020 intersected the C460 Zone returning 1,810 g/t Ag.Eq1 over 14.62 metres (m) including 2,466 g/t Ag.Eq1 over 9.57 m and 682 g/t Ag.Eq over 4.00 m. This intercept is located approximately 15 m below the last mine development in this area, with similar high-grade mineralization: 1767 EL composited historical channel samples graded 974 g/t Ag.Eq over a strike length of 23 m and width of 2.86 m. Hole Q-23-017 intersected the Quebradillas Zone returning 266 g/t Ag.Eq. over 6.03 m including 496 g/t Ag.Eq over 1.67 m and 354 g/t Ag.Eq over 0.60 m. Hole Q-23-019 intersected the Quebradillas Zone returning 523 g/t Ag.Eq over 1.22 m.

Greg McKenzie, President and CEO, said, "C460 was the largest zone mined when Quebradillas was previously in production by First Majestic Silver. The high-grade mineralization extends the C460 Zone at depth to the south where limited drilling was previously performed. The mineralization in this area is higher-grade, and wider, than the previously mined stopes immediately above. We were pleasantly surprised by the much higher grades in this area and will follow up with additional drilling in this location in 2024."

The C460 Zone is a sulphide replacement vein striking 344 degrees and dipping 63 degrees to the northeast with a known strike length of 425 m. The zone is mineralized over a vertical extent of 570 m and its thickness varies up to 8.5 m. The replacement vein is concordant to bedding in the sediments and mineralization is comprised of pyrite, pyrrhotite, galena, sphalerite, arsenopyrite, acanthite, and freibergite.

Hole Q-23-020 was drilled to target the C460 Zone, successfully intersecting replacement mineralization, returning 1,810 g/t Ag.Eq over 14.62 m (56.00 to 70.62 m), including 2,466 g/t Ag.Eq over 9.57 m (60.50 to 70.07 m) and 682 g/t Ag.Eq over 4.00 m (56.00 to 60.00 m). This intercept is located approximately 15 m below the last mine development in this area, with similar high-grade mineralization. The composited weighted average grade of historical channel samples from the 1767 EL stope returned 974 g/t Ag.Eq over a strike length of 23 m and average width of 2.86 m.

The Quebradillas Zone is comprised of fault associated quartz-carbonate veins and breccias striking east and dipping 86 degrees to the south (088/86) with an average width of 1 to 2.5 m. The structure pinches and swells, cutting across the sediments and granodiorite stock. Mineralization in the vein consists of pyrite, pyrrhotite, arsenopyrite, galena, sphalerite and acanthite.

Hole Q-23-017 successfully intersected the Quebradillas quartz-carbonate vein and breccia mineralization returning 266 g/t Ag.Eq over 6.03 m (36.65 to 42.68 m), including 496 g/t Ag.Eq over 1.67 m (36.65 to 38.32 m) and 354 g/t Ag.Eq over 0.60 m (40.12 to 40.72 m). This intercept is located approximately 16 m above the last mine development in this area, with similar high-grade mineralization. The composited weighted average grade of historical channel samples from the Quebradillas West 1892 EL stope returned 234 g/t Ag.Eq over a strike length of 18 m and average width of 2.34 m.

Hole Q-23-019 intersected the Quebradillas breccia mineralization returning 523 g/t Ag.Eq over 1.22 m (45.98 to 47.20 m). This intercept is located approximately 31 m below the last level of development in this area, with similar high-grade mineralization: The composited weighted average grade of historical channel samples from the Quebradillas East 1892 EL stope returned 233 g/t Ag.Eq over a strike length of 29 m and average width of 2.16 m.
