GR Silver Mining has assembled an extraordinary portfolio of highly prospective mining concessions
in the historic Rosario Mining District, Sinaloa, Mexico. At the core of this portfolio is the 432 78 km 2
Plomosas Silver Project, which includes the Plomosas Mine Area and, the San Marcial Area, and the
La Trinidad Area. The Company also controls 300 270 km 2 of key non-core concessions adjacent to
the Plomosas Project that are well situated providing incremental growth potential and possible
future business opportunities. Combined, GR Silver Mining’s concessions control most of the silver-
gold-lead-zinc mineralized zones identified in the eastern Rosario Mining District.
In May 2023, GR Silver Mining published a NI 43-101 technical report and mineral resource update for the Plomosas Project. The tables below summarize the mineral resource estimate for the Plomosas Project.

Rosario Gold-Silver Project
As part of the March 2020 acquisition of the Plomosas Property, GR Silver Mining also acquired a package of three concessions strategically located adjacent to Rosario town. These concessions may host extensions to the historical multimillion-ounce Rosario gold-silver mine, which was reported to have closed in 1941 after an operating life spanning over 250 years.
