comparison with sfr, page-7

Just to put 766,000 ounces of gold in context with SFR copper resource, current price of gold is about 1360 an ounce and copper is $8200 a tonne, so a tonne of gold is equivalent to six ounces of gold, so 766,000 ounces of gold is equivalent to an extra 127,700 tonnes of copper on top of SFR's current resource.

These are very rough figures and neglect the fact that extracting another metal can increase the cost of mining.

From the latest SFR resource update on the ASX, "Oxide copper resource and a new laterite gold resource increase the overall metal inventory of Degrussa to 644,000 tonnes of copper and 724,000 ounces of gold"

http://af.reuters.com/article/metalsNews/idAFN2943117020101129 is an article that discusses the expected increase in copper prices.
"NEW YORK, Nov 29 (Reuters) - A growing production deficit
is expected to lift the price of copper through a series of
all-time highs and a peak well above $11,000 per tonne in 2013, metals research and consulting firm GFMS said in its Quarterly Three-Year Copper Forecast report."

MNC has no gold, but their current resource of 4.7 million tonnes of copper is huge. SFR is the current darling but one day the market is going to wake up to MNC.
