CHILE – Vancouver-based Far West Mining says that locked cycle tests using sea water on a sample from its Santo Domingo copper project in the northern part of the country achieved “outstanding” results. Copper recovery was 88.5% to a concentrate grading 32.6% Cu. Gold recovery into the copper concentrate was 68%.
The locked cycle test results using sea water had better results than those using fresh water, and better than batch tests using both sea water and fresh water. The company also said that the concentrate will not carry levels of contaminants that will attract penalties. The concentrate will be washed with fresh water to reduce chloride to acceptable levels.
The Santo Domingo iron-oxide-copper-gold (IOCG) project is estimated to contain 2.85 billion lbs of copper. Details of project can be read at www.FarWestMining.com.
