The Cu/Au grades in the top 400mtrs are in my view uneconomical, meaning it lowers the grade of the Pb/Ag if mined concurrently and outright uneconomical if mined on a stand alone basis. Richard has stated in the past that they will not mine the Cu/Au in the initial years. My thoughts are that they could look at sending the ore to either A1M or the other mob in cloncurry or leave what they can in situ and stockpile the rest and blend with the high grade stuff in years 3 or 4. The higher grade stuff starts around 400 to 500mtrs below surface. So maybe year 3 or 4 they add a copper circuit from the fcf. A copper circuit later makes sense as it lowers the initial capex. I think that the best option is to truck the ore to another site around Cloncurry to increase cash flow in the initial years of production.
