Drilling has begun within the 9.4-kilometre Parkin Offset in Sudbury, as part of a joint venture between Wallbridge Mining Company and Impala Platinum Holdings Ltd.
More than 5,000 metres of diamond drilling and borehole geophysics will be undertaken to follow up on platinum, palladium, nickel, copper and gold mineralization in the area.
"We are very excited about this next phase of drilling with Impala on the Parkin Offset joint venture," Marz Kord, Wallbridge president and CEO, said in a news release. "We have identified very significant grades in the Milnet 1500 Zone, beneath the past-producing Milnet Mine. We look forward to exploring the extent of the mineralization."
Drilling will test 100-metre step-outs from the Milnet 1,500 Zone and shallower targets beneath and near the past-producing Milnet Mine.
The Milnet Mine reported past production of 157,130 tons averaging 2.25 g/t platinum, 2.98 g/t palladium, 0.93 g/t gold, 1.49 per cent nickel, and 1.54 per cent copper.
Drilling beneath the Milnet Mine in 2009, Wallbridge discovered the Milnet 1,500 zone intersecting 14.24 metres containing 1.50 g/t platinum, 2.52 g/t palladium, 3.99 g/t gold, 0.78 per cent nickel, and 2.57 per cent copper from 1,499.66 to 1,513.90 metres down hole.
More recent drilling intersected 8.0 metres containing 1.40 g/t platinum, 2.68 g/t palladium, 0.23 g/t gold, 4.11 per cent nickel, and 0.60 per cent copper from 1,473.00 to 1,481.00 metres down hole.
The Parkin Offset joint venture includes the Milnet Mine property, a southern block of claims which are held 1.5 per cent by Xstrata Nickel, and two blocks of claims on either side of the Milnet Mine property which are subject to an option and joint venture agreement between Wallbridge and Champion Bear Resources Ltd.
The Parkin Offset Dyke hosts platinum, palladium, nickel, copper and gold mineralization typical of other offset dykes in Sudbury with examples at Vale's Copper Cliff North and South mines and Vale's Totten Mine development. Exploration is at an early stage and the property has very significant discovery potential.
