I think you are reading the chart wrong.  The 121,000 oz number for gold is total production from the primary sulphides from 2017 to 2024.  This is the Oct 2012 presentation.  The 146,000 oz gold prod is estimated from May 31, 2012 to Mar 31, 2013 for oxides.  36,000 oz gold prod is the total expected from mid-2013 to 2014 from the supergene ore.  For Q4 I believe it is mainly Harena.  But the above oxide forecast underestimates because Q3 surpassed expectation and so far in Q4 they indicated that would also be the case and total oxide gold production will likely exceed their top end of 300K oz for 2012.  And now they also indicated oxides will continue into Q2-2013.


So my guess is that Q4-2012 will likely have 45K-50K oz gold prod, Q1-2013 40K, and Q2-2013 25K-30K to be followed by 6K for the remainder of 2013 as byproduct credit from the copper rich supergene mining.


This will likely be a dead stock now for the next eight months likely to consolidate between $4.40 to $5.  Q4 cash generation will be further mitigated by a large whopping tax payment plus further copper plant capex. Then Q1 and Q2 gold production will have much higher cash cost from lower grade Harena ore and higher strip as the gold oxides wind down.
