About the Plomosas Project
The Plomosas Project, including the recent high-grade silver discovery in the San Marcial SE Area,
is progressing in 2025 as an emerging high-grade silver district located in southwestern edge of the
Sierra Madre Occidental,
Sinaloa, Mexico
. The Plomosas Project, covering 7,823 ha, including the
historical Plomosas Underground mine. benefits from mine infrastructure, road access and existing
permits associated with past-producing mining sites. The district contains intermediate to low-
sulfidation epithermal silver and gold mineralization, hosted in hydrothermal breccias and veins.
Recent success in exploration and drilling has delineated wide, high-grade, shallow hydrothermal
breccias in the San Marcial Area, including the SE Area discovery, where step-out drilling is
underway in 2025, aiming for continuous resource growth. At the historical Plomosas Mine, where
Grupo Mexico operated the underground mine from 1985 to 2000, exploration, underground
sampling and metallurgical programs are being conducted to support future decisions regarding the
implementation of a Bulk Sampling Test Mining Program
