Summary:
The polymetallic mineralization at the San Vicente Property is present as vertically continuous fault hosted veins, replacements of brecciated faults, and mineralization in dacitic dikes. The mineralized structures are on the order of one to five metres wide, dip moderately to steeply, and trend generally towards the northwest.
The San Vicente Property contains a polymetallic deposit formed by hydrothermal systems associated with repeated calc-alkaline intrusions and their extrusive products forming vein type and disseminated polymetallic deposits. Mineralization in the district is known to cover an area of three by four kilometres to a depth of 300 metres. It consists of replacement veins filling preexisting faults, replacements in brecciated conglomerates in the San Vicente fault, and mineralization in dacitic dikes. Wide veins form in the west-northwest trending structures, with widths of between two and six metres, while veins present in the northwest structures are thinner and shorter. The widest and highest grade veins form in northeast trending faults.
Mining Methods
- Shrinkage stoping
- Longhole stoping
- Dry waste backfill
Summary:
The underground mining method used at San Vicente is primarily long hole open stoping with waste backfill as well as conventional shrinkage stoping. Access to the mine for workers and equipment is provided by ramps and the Pelayo shaft while waste and ore material is brought to the surface using both haul trucks on the ramp and hoisting at the Pelayo shaft. Locomotives are used to move broken ore and waste on the levels in the conventional areas of the mine.
