SAN RAMON SILVER MINE

San Ramon Silver Mine

The San Ramon Mine is located 5 kilometres south of the Guadalupe mill. San Ramon has been a significant contributor to production since 2008. In 2014, the Company discovered new high-grade silver zones in the San Ramon Deeps area and mining of this area began in Q4 2014. During the first quarter of 2021, the San Ramon Deeps Mine provided 18% (Q1 2020 – 22%) of feed to the Guadalupe mill. Monthly average mining grades at San Ramon during the quarter ranged from 162 to 171 g/t silver.

To date this vein has been mined on Levels 12 through 29 over a length of up to 180 metres and widths of 2 to 17 metres. Production during Q1 2021 was from Levels 24, 27, 28 and 29. Size and grade of San Ramon Deeps are decreasing with depth but new drilling is planned to test potential extensions of the zone updip and to the south
