MacDonald Mines Exploration Ltd. has shipped approximately 100kg of oxide sands to SGS Minerals Services to conduct metallurgical testing and investigate potential processing methods for the Wawa-Holdsworth Pyrite Project.
The Wawa-Holdsworth Pyrite prospect is a gold and silver bearing, black colored, “oxidized cap” (oxide sands) that overlies a massive pyrite zone. The strike of the pyrite zone runs over 2 km and its thickness ranges from 2 to 10 metres. The oxide sands reach a depth of more than 8 metres. A sampling program of the oxide sands conducted in 2002 produced an average grade of 4.03 g/t gold and 30.89 g/t silver. Preliminary mill testing by normal vat leach processing without crushing or other processing resulted in a 94 percent gold recovery.
“In the few months our team has worked on the Wawa-Holdsworth Project, we’ve already initiated a bulk sampling program of the oxides sands, initiated metallurgical test work on the immediate gold target on the property and secured a 100 percent interest in the property. Following spring breakup, the company will ramp up its sampling program to better define the oxide sands and continue to prepare for their potential extraction,” said Quentin Yarie, MacDonald’s president and CEO.
The metallurgical testing initiated by MacDonald Mines will investigate simple processing methods that require no chemicals to concentrate the gold and silver and achieve the highest possible recovery.
To evaluate multiple options the following will be completed:
• Head assays
• Mineralogical characterization of the feed
• Bond ball mill grindability test
• Heavy liquid separation testing
• Knelson Concentrator testing
• Flotation and leach testing on gravity tailings as diagnostic test
