Project Overview
San Dimas is located on the border of the Durango and Sinaloa states, and is considered to be one of the most
significant precious metals deposits in Mexico. The mine is owned and operated by First Majestic Silver
Corp. ("First Majestic"), having been acquired in 2018 as a result of the acquisition of Primero Mining
Corp.
The district comprises more than 100 epithermal, bonanza-type, gold-silver veins, and hosts over 500 km of
underground development. The mine is a low-cost producer of gold and silver. It is situated within a very
large (15 square kilometre) mining district, and has been in continuous production for well over 100 years.
The mine consists of five ore zones or blocks: Central, Sinaloa Graben, Tayoltita, Arana Hangingwall and San
Antonio West.
San Dimas utilizes long-hole stoping and mechanized cut-and-fill mining methods with all ores processed at
the Tayoltita mill. After milling, cyanidation, precipitation and smelting, the doré bars are poured and
transported to refineries in Mexico and the United States. Over the substantial mine life to date, San Dimas
has demonstrated a strong track record of resource conversion and the mine continues to exhibit strong
exploration potential. Since First Majestic acquired the mine, they have been developing a long-term mine
and mill automation plan for the future of the operation.
