Ann: Acquisition of Advanced Copper-Silver Project in Peru, page-12

Below is from the Silver Standard website.

• 2010 Scoping study: A scoping study for a mining-milling operation at Berenguela was prepared in 2010. The study proposes the recovery of silver by conventional cyanide leaching followed by the Merrill-Crowe process, the recovery of copper by direct electro-winning and cementation, and the recovery of manganese dioxide by electro-winning. Two mining scenarios were evaluated, one based on a 4,000 tonnes per day operation and another at 1,000 tonnes per day.

I think some of the answers will be in the 2010 Scoping Study report, but it seems this was a second tier project for Silver Standard, probably because of profitability compared to other projects they had ongoing.

I also saw that they paid around $8M for the project as I skimmed through the filings.

If I can find the Scoping report I will share, but so far no luck.
