Nexa Resources (TSX: NEXA; NYSE: NEXA) has released a preliminary economic assessment (PEA) for a potential underground mine at its Hilarion project in Peru – one of the largest undeveloped zinc projects in Latin America.
Hilarion, 230 km north of Lima, would produce 115,000 tonnes zinc, 2.6 million oz. silver and 20,000 tonnes lead each year, representing 150,000 tonnes zinc equivalent over an initial mine life of 16 years, according to the study.
The proposed operation would consist of a 10,000 tonne-per-day mine and a conventional flotation plant producing bulk lead-silver and zinc concentrates at an annual throughput of 3.65 million tonnes of ore. (The average overall production rate would be 7,800 tonnes per day over the full 16 years but in excess of 10,000 tonnes per day from year two until year eleven.)
