Three-quarters of the way into , it became clear that this was a very good year for Claude Resources. The Saskatoon-based gold miner had increased its year-to-date gold production by 63 per cent over , thanks in part to a successful implementation of the Alimak mining method at its Seabee gold mine in Saskatchewan. Successful users of the technique have found that it accelerates their path to production by centring development work within the ore body. In regular open stoping, overcuts and undercuts provide access to the ore along strike.

It allows Maroc the opportunity to share its Alimak expertise with staff of Golden Star Resources while training them to take over from it on a progressive basis during the contract period. The company had earlier stated that gold production was expected to resume at the Prestea concession by mid after going through successful redevelopment over the last 2 years. The mine was previously in production 14 years ago. Mode of selection The Alimak mining method, which Manroc prides itself as the inventor, uses an Alimak raise climber to develop a raise in the ore body followed by drilling production holes in the ore body and blasting.

The method requires less ore and waste support development than conventional shrinkage mining and is more efficient to bring into production and to operate. It is also safer and more cost effective, Mr Agala said. He said that Manroc was selected after a competitive bidding process that involved three companies.

The President and Chief Executive Officer of Golden Star, Sam Coetzer, had earlier said in a statement that the appointment of a mining contract was the next important step in efforts aimed at reviving the mine. Prestea Prestea Underground is a narrow, high grade deposit with mineral reserves of 1.

It was in production throughout the 20th century on an intermittent basis and has historically produced in excess of nine million ounces. It was placed on care and maintenance by Golden Star, while evaluation and exploration activities continued.

Nethod advantage is easily visualized if one imagines the hangingwall as a fractured beam or plate. With less development, faster ore access, better ground control, and faster overall mining, it is easy to see how raise mining will cost less than regular open stoping. All packed and ready to go Eavan Moore. Fill fence and piping if required.
