ONTARIO – Preliminary metallurgical results are positive on samples from the Wawa-Holdsworth gold-bearing oxide sands, according to MacDonald Mines Exploration of Toronto. The tests were conducted by SGS Mineral Services in Lakefield, Ont.

MacDonald says the sands are amenable to sampling, crushing and flotation processes. No caustic treatment is necessary, and the waste material is inert at >70% silica/quartz. It also appears that treatment will have low power requirements.

Further testing is planned to identify the main forms of precious metals mineralization, optimize the grind size for the rougher, and select flotation reagents. The effects of both open and closed circuit regrinding will also be examined.

The Wawa-Holdsworth project is about 20 km northeast of the town of Wawa, neighboring the Island Gold mine as well as the Magino and Borden projects. The oxide sands are known to extend over 2 km of MacDonald’s holdings.

MacDonald plans to concentrate the sands and sell that for the contained gold, silver, platinum and palladium.
