White Rock Minerals Ltd (ASX:WRM) has intersected high base and precious metal grades while testing extensions of mineralisation in two prospective areas at Dry Creek deposit of its Red Mountain project in Alaska.
The first intercept is the best of all holes drilled at the Discovery lens, hitting 4.7 metres at 19.5% zinc, 7.8% lead, 466 g/t silver, 6.9 g/t gold and 1.5% copper for 49.7% zinc equivalent grades, including 1.6 metres at 18.5 g/t gold.
The second hole at Fosters lens intersected 4.3 metres at 4.8% zinc, 2.3% lead, 1,435 g/t silver, 2.2 g/t gold and 0.5% copper for 43.2% zinc equivalent grades.
Potential to rapidly expand resource
The two assays received are the first of the 2018 program, with a further two drill holes completed and another underway.
Drilling is now targeting extensions of the two existing deposits, Dry Creek and West Tundra.
These have a resource base of 16.7 million tonnes at 8.9% zinc equivalent grades, including a high-grade component of 9.1 million tonnes at 12.9% zinc equivalent grades.
White Rock managing director Matt Gill said the drilling represented a significant extension to the Dry Creek deposit and highlighted the upside potential for expanding the resource at Dry Creek, both in terms of grade and size.
“Exciting VMS deposit”
Gill said: “Dry Creek is an exciting VMS deposit as it shows great variation in thickness that has the potential to rapidly add to the resource.
“In addition, we are continuing to see more copper as we explore to the east, supporting an early interpretation that the VMS system may be improving towards the east and at depth, where improving zinc grades could also be expected.
“And all this before we have really got our teeth into testing some of the best of the more than 30 already identified regional exploration targets within our 143 square kilometre land package,” he said.
