2009— San Gold has 300 non-union employees, over 15 years of gold resources, and a
conservative base case mine plan to produce 50,000 ounces in 2009, climbing to
250,000 ounces per year by 2012 at an all-in cost of US$360 per ounce.
From what I can gather, the fact sheet is telling us that there is enough ore already proven to supply the mine over the next 15 years at the quantities stated:
2009 - 50,000 ounces
2010 - 100,000 ounces
2011 - 200,000 ounces
2012 - 2024 - (12 years x 250,000 ounces) = 3,000,000
Total proven and probable - 3.35 million ounces of conservative base case mine plan ounces of gold.
If gold stays around 900 bucks, that's $1.8 billion profit
