This mineral resource estimates for the Carmen and Veta Minitas deposits include a high grade mineral resource considered to be potentially amenable to underground mining, and which is surrounded by a lower grade mineral resource halo, some of which may be amenable to open pit mining.
"We are pleased with this new mineral resource estimate for the Veta Minitas deposit, which is a valuable addition of high grade gold-silver mineral resources to the recently revised mineral resource estimate for the Carmen Deposit," said
The base case total resource estimate, inclusive of the high grade estimate, is shown in the table below.

Mineral Resource Estimation Process
The new mineral resource estimate for the Veta Minitas Deposit at Monterde was prepared by
This new mineral resource estimate for Veta Minitas includes a high grade mineral resource considered to be potentially amenable to underground mining, and which is surrounded by a lower grade mineral resource halo, some of which may be amenable to open pit mining.
Mineral resources that are not mineral reserves do not have demonstrated economic viability. Mineral resource estimates do not account for mineability, selectivity, mining loss and dilution. These mineral resource estimates include inferred mineral resources that are normally considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. There is also no certainty that these inferred mineral resources will be converted to the measured and indicated categories through further drilling, or into mineral reserves, once economic considerations are applied.
The high grade mineral resource estimates at various cutoff grades are shown below, with the base case bolded:
