Toro Energy has completed the extraction of a bulk mineralized sample from a resource test pit at the Wiluna Uranium project in Western Australia.
There has been 22,100 tonnes of material extracted from the test pit, including 12,200 tonnes of barren topsoil and waste, 4700 tonnes of 100-200ppm mineralized material, 2200 tonnes of 200-500ppm material and 3000 tonnes of material greater than 500ppm.
The test pit has successfully demonstrated that the proposed mining method using a Vermeer continuous mining machine is very effective with excellent cut rates.
It has also demonstrated the grade control and mineralized material selectivity system; similar distribution of mineralized material grades to that seen in drilling data; and the dust collection system on the miner worked very well.
The test pit provided a bulk mineralized material sample for further definitive test work allowing Toro to advance the test work stage of the bankable feasibility study and finalize a processing option.
Pit operations began at the end of July with initial pre-stripping of barren surface soil and material to allow commencement of selective mineralized sample extraction. A Vermeer continuous mining machine successfully cut and mined the calcrete hosted mineralized and waste material, which was then removed with ancillary loading and trucking equipment.
Toro is targeting uranium production at Wiluna in 2013.
