True thickness at the reconnaissance scale is an estimate based on drill hole angles to structures.
The drilling has been conducted by Globexplore, an experienced diamond drilling service company, utilizing low environmental impact, man-portable drill rigs. Globexplore has an excellent environmental, community and safety record in Mexico. This program was carried out under strict COVID-19 safety protocols and was assisted by the consulting group Geotech Evaluation Services ("GES").
Prior to this 2022 program of 8 holes for 2,665 metres, there have been two previous drilling campaigns on the
Sandra is situated north of the town of
The Project covers almost 70 square kilometres of contiguous mineral concessions and includes multiple mineralized epithermal quartz veins, disseminated horizons and breccia structures. These mineralized features form a high-level silver-gold-base metals system, hosted in andesitic and rhyolitic rocks, centered on a large rhyolite dome complex in the north, intrusive related vein systems to the west, and silver-bearing systems in smaller rhyolite dome complexes to the southeast. Intense alteration zones and fluid flooding in permeable formations indicates the presence of bulk tonnage targets.
An initial mineral resource estimate at Sandra was released in 2016 for the disseminated silver discovery of the Boleras Deposit. Located at surface in the southeastern part of the Project, the Boleras Deposit contains an Inferred Resource Estimate of 9.8 million tonnes, grading 106 g/t Ag, for a total of 33.3 million ounces of silver (see news release 31 October 2016).
Excellent infrastructure exists in the Sandra area, including paved road access, electrical power, water and manpower from nearby communities. Community engagement is an important part of the ongoing Environmental, Social and Governance (ESG) efforts.
