In March 2017, Americas Silver purchased an option to acquire a 100% interest in Hochschild Mining Plc’s San Felipe silver-zinc-lead project located in Sonora, Mexico. The company continues to evaluate the property prior to a decision to exercise its purchase option. The previous option holder, Santacruz, published a resource and PEA in 2014.
Mineral Reserve and Mineral Resource Estimates
Notes for Mineral Reserve and Mineral Resource Estimates:
CIM Definition Standards were followed for mineral resource estimates.
Mineral resources are fully diluted to the 2mx3mx2m block size and estimated at a cut-off grade of 2.5% zinc equivalent which incorporate metal recoveries.
Mineral resources are estimated using metal prices of US$18.00/oz Ag, US$3.00/lb Cu, US$1.05/lb Pb, and US$1.05/lb Zn.
Numbers may not add due to rounding.
The current or previous San Felipe resource estimates are not included in the Company’s June 30, 2017 reserve and resource estimates.
Increase is based on comparison to the previous resource estimate from the technical report titled “2014 Resource Estimate and PEA”, San Felipe Project, Sonora, Mexico”, with an effective date of September 4, 2014 and amended date of June 29, 2016, completed for the previous option holder, Santacruz Silver Mining Ltd.
