GR Silver Mining Confirms Down Dip and Lateral Continuity of SE Area High-Grade Ag Discovery

VANCOUVER, BC, Sept. 7, 2022 /CNW/ - GR Silver Mining Ltd. ("GR Silver Mining" or the "Company") ( TSXV: GRSL) (OTC-BB:GRSLF) (FRANKFURT:GPE) – is pleased to announce that follow up down dip and lateral drilling has successfully intersected extensions to the new high-grade Southeast ("SE") Area silver (Ag) discovery as a potential expansion of the San Marcial Resource Area, at the wholly-owned Plomosas Project in Sinaloa, Mexico. Surface drill holes SMS22-11 and SMS22-12 both intersected mineralization similar to the previously announced discovery in the SE Area, with multiple intervals grading over 1,000 g/t Ag, hosted in a wide zone with a predominant presence of Ag-rich hydrothermal breccia and stockwork systems. Drill hole SMS22-12 was drilled beneath the discovery hole – SMS22-10, which intersected 101.6 m at 308 g/t Ag (see News Release dated August 8, 2022) – confirming a 90 m depth extension of the Ag-rich zone, while SMS22-11 was drilled along the expected strike, 85 m to the SE of the discovery hole (Figure 1), confirming the lateral continuity in that direction.
