Breaker Resources says it can recover 95 per cent of the gold at its Lake Roe project near Kalgoorlie.

A metallurgical study found that as much as 39 per cent of gold from the Bombora discovery is recoverable via gravity concentration — a simple, low-energy technique that separates minerals based on differences in gravity.

Tests have shown that cyanide leaching — a chemical technique commonly used to recover gold from gold-bearing ores — would recover the remaining gold within within four hours on weathered and fresh samples.

“The testwork indicates favourable gold extraction characteristics with no significant processing issues identified,” chairman Tom Sanders told investors.

“While the testwork is preliminary, the results highlight the potential for a conventional gold processing plant that can cost-effectively treat open pit and underground ore.

The 2.2km Bombora discovery at Lake Roe forms part of an 8 km gold system, hidden typically 5 to 10 metres underground.

Breaker (ASX:BRB) raised $10 million in August to gear up for its maiden resource at Lake Roe.

Last month Mr Sanders saw his shareholding in the company drop from 16.63 per cent to 14.51 per cent, following the capital raise.

Mr Sanders told Stockhead they are now drilling to determine the size of the resource.

He says the reason why this particular strike hadn’t been found before, in the prolific and well explored Kalgoorlie region, is because it is covered with a thin layer of sand.
