Several years ago I remeber reading that, Silverado Gold Mines production cost was projected to be around $500/ton; for the sake of cost with everything more expensive, lets say Silverado's production cost is now $600/ton. Remember, Silverado has 4 massive Antimony veins, and that Antimony has been declared a strategic metal by several countries. Bottom line, Silverado's production cost could be close to half of what the majors pay to mine. GRIM

Taking Another Look At Barrick Gold After Its Slump

Barrick Gold Corporation’s has seen its stock price plummet in the last month from about $21 to $14-15, a precipitous drop of nearly 25%. Year to date it’s even uglier with the shares down 60%. It’s not just Barrick Gold ABX +0.58% that’s reeling – almost all miners operating in the precious metals space are sinking in the same boat. However, as the world’s largest gold producer, Barrick gets intense scrutiny from investors as a barometer for the industry’s health

Players like Kinross, Newmont and Goldcorp GG +0.33% have production costs in the range of $1,038-1,135 per ounce. The costs are not stagnant, and they are rising due to rising costs of labor, energy, exploration and development in geographically challenging regions, and royalty payments to governments across the world. Barrick expects a cost figure of $950-1,050 per ounce in 2013.
