Wouldn't suprise me if SUR let out an option to produce copper in the tagpura area. It must be rich, like a gold mine.
Quote from Sur Website;
TAGPURA COPPER - GOLD PROJECT
Approximately 5 km to the south-east of the COMVAL project the Company also controls a 6 km long belt of copper-gold porphyry deposits and undrilled geophysical anomalies which may represent further undiscovered copper-gold mineralization.
Some 23,000 meters of drilling and 4000 meters of underground development was carried out by a previous operator in the 1970's delineating about 80 million tonnes of mineralization grading about 0.4% copper, 0.5 g/t gold and 5 g/t silver.
(This "resource" does not currently conform to CIM reporting standards as the Company has not confirmed the accuracy of all the data).
As a result of this work a 10,000 t/d operation was placed into production in 1979 but closed 18 months later reportedly because of high oil prices, low copper prices and excessive bank debt.
