Just some notes:


Recovery of metals is not bad at 90%Cu, 75Au & 75%Ag

Power and water are great

Main risk to marketability is the arsenic (roaster technology can achieve saleable concentrates)

TMF (Tailings Facility) Land needs to be purchased for this, perhaps that is why Guistra is buying farmers fields in Mexico

Teck's CESL (Richmond) pilot plant ran a cycle of ore and recovery was 97.5%CU & 85%Au/Ag but it hasn't been commercialized yet

Average wage for a tradesman onsite is 25K and shift workers 16k

Now I see why Canada's costs are so much higher (4X) and Mexico has a huge advantage
