Some people here seem misunderstand all-in-cost (AIC) as all-in-sustaining-cost (AISC) Please read the link to know AIC which includes all of cost for the mining life cycle (from exploration to closure) should be much higher than AISC. BAA has a AIC $888/OZ. I am sure you cannot find any other company has this low AIC. http://www.ey.com/Publication/vwLUAssets/EY_-_All-in_sustaining_costs_and_all-in_costs/$FILE/ey.com_gl_cost%20per%20ounce.pdf
