About the Plomosas Project
The Plomosas Project, including the recent high-grade silver SE Area discovery in the San Marcial Area, is an emerging high-grade silver district located in southern Sinaloa, Mexico. The 43,187 ha Plomosas Project includes past-producing historical mining sites benefiting from previous mine infrastructure, road access and existing permits. The district contains intermediate to low sulphidation 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 initial drilling incorporated in the updated resource estimation for the Plomosas Project unveils an exploration opportunity for continuous resource growth.
