Good estimates. What I can add is an observation from experience; Viceroy's Castle Mountain Mine produced about 1.5 million oz from their main "Lesley Ann" pit (similar grades to Represa). The drilling at Camino Rojo has already defined an area of bulk mineable values the exceeds the aerial extent of the Lesley Ann Deposit. The Lesley Ann deposit was a epithermal/hot springs deposit drivien by rhyolitic dome intrusions, with a large footprint of clay alteration.
Is there an extensive halo of alteration at Camino Rojo? I smell elephants..
