[{"type":"text","content":" VANCOUVER, BC, May 19, 2026 /CNW/ - GR Silver Mining Ltd. (\"GR Silver Mining\" or the \"Company\") (TSXV: GRSL) (OTCQX: GRSLF) (FRANKFURT: GPE) is pleased to announce outstanding drill results from hole SMS26-04 in the SE Area of San Marcial. These exceptionally high silver grades represent the \"best ever\" drill results from the San Marcial deposit, confirming the robust geological model, and the continuity of high-grade silver mineralization controlled by key structural features.Highlights of 2026 Step-Out Drilling at San MarcialSMS26-04 intersected two well-defined mineralized zones located at the upper and lower contacts of the chlorite–hematite-rich breccias, associated with stockwork zones and andesitic to dioritic dykes emplaced along multiple structural intersections. High-grade silver mineralization is developed within the chlorite–hematite-rich breccias at the contact between the upper Oligocene volcanic sequence and the lower Jurassic volcano-sedimentary units (Figure 2). The exceptional silver grades encountered in SMS26-04 (Table 1) highlight the strong structural control of the mineralizing system and further support the exploration potential of key inflection zones, including structural jogs and shear zones, as priority targets for additional high-grade mineralization.45.1 m true width (TW) at 1,623 g/t Ag, from 267.85 m down holeincluding 18.85 m TW at 3,846 g/t Ag with 0.7% Pb and 2.5% Znincluding 8.25 m TW at 8,579 g/t Ag with 1.6% Pb and 5.5% Zn20.6 m TW at 32 g/t Ag from 328.60 m down hole,including 7.1 m at 51 g/t Ag and 0.15 g/t AuHigh-grade silver mineralization in SMS26-04 consists of multi-stage hydrothermal breccias, subsequently overprinted by polymetallic silver-lead-zinc events (Figure 3). These mineralizing events are spatially associated with the intersection of E-W, N-S, and NE-SW structural trends, which generate high-grade shoots and provide a key exploration vector for targeting additional high-grade mineralized intersections within the San Marcial breccia-hosted body.Results from SMS26-04 also confirm the continuity of near-surface mineralization previously intersected in drill holes SMS22-16, which returned 123.1 m at 112 g/t Ag (see News Release dated October 17, 2022), and SMS22-22, which returned 82.7 m at 121 g/t Ag (see News Release dated January 16, 2023), as depicted in Figures 1 an...
