The San Jose mine was commissioned in July 2011 and began commercial production in September 2011 at a rate of 1,000 tpd. In September of 2013, the mill was expanded from 1,150 tpd to 1,800 tpd and in April 2014, the mill was further expanded to 2,000 tpd without incurring in additional capital investments. Expansion of the mill from 2,000 tpd to 3,000 tpd was initiated in the first quarter of 2015 and successfully commissioned on time and under budget in July 2016.
San Jose is located in the Taviche Mining District (Latitude 16° 41' 40" N, Longitude: 96° 42' 00" W) in the southern portion of the state of Oaxaca, approximately 47 road kilometers (one hour drive) south of the city of Oaxaca. Access to the property is excellent and local infrastructure is good.
The San Jose deposit is a low sulfidation epithermal vein system characterized by mineralized multiphase quartz-carbonate-sulfide veins, hydrothermal breccias and stockwork veining. The mineralized system is hosted within a sequence of Tertiary andesitic volcanic and volcaniclastic rocks.
The Brownfields exploration program budget for 2020 at the San Jose Mine is US$4.9 million, which includes 17,600 meters of diamond drilling and 500 meters of underground development for drilling access, platforms and services. Underground exploration drilling will focus on the shallow, north extension of the Trinidad vein and the sub-parallel Victoria mineralized zone, while surface drilling will test two new targets to the south of the mine.
