Intial 25 Mtpa feed x 0.35% copper x say 85% copper recovery = approximately 75,000tpa copper metal. MGO plans to increase throughput to 50Mtpa eventually (150,000 tpa copper). By-product credits for moly and gold. At these grades revenue is not the issue, but rather capital costs and operating costs. I like the story - not sure about tailings disposal though - deep sea tailings disposal probably preferred but lets see what happens with the Ramu court case.
