Vince, the Breccia zones in general extend about 1000 meters below the highest outcroppings at that location. Some of the breccia's are enriched as far as 500 meters below ground even though as much as 200 meters has already been mined from the primary breccia, the Donoso. The Breccia zones are being mined by open pit methods. The nearby Rio Blanco mine is mining the underlying porphyry deposit by underground methods. Copper grades as high as 4% extend to the 500 meters level-created by supergene oxidation processes-leaching of surface copper concentrating at the water table level.
