‘Exceptional’ zinc, lead, silver & gold grades at White Rock’s Red Mountain Project
White Rock Minerals Ltd (ASX:WRM) this morning reported that assay results from recent drilling have extended the mineralisation at its 100% owned high-grade zinc VMS project at Red Mountain in Alaska. The diamond drilling results are part of WRM’s maiden drill campaign at the Red Mountain project.
Drilling intersected massive sulphide mineralisation in the first two diamond drill holes targeting the down plunge extension of mineralisation in the Discovery lens and the Fosters lens of the Dry Creek deposit at Red Mountain.
These first two drill holes of the 2018 program to test the down plunge extension of mineralisation at both the Discovery lens and the Fosters lens at the Dry Creek deposit returned exceptional zinc, lead, silver and gold grades, as follows:
- DC18-79: 4.7m at 19.5% zinc, 7.8% lead, 466g/t silver, 6.9g/t gold and 1.5% copper for 49.7% ZnEq, including 1.6m at 18.5g/t gold.
- DC18-77: 4.3m at 4.8% zinc, 2.3% lead, 1,435g/t silver, 2.2g/t gold and 0.5% copper for 43.2% ZnEq.
Drilling is now targeting extensions of the two existing deposits, Dry Creek and West Tundra, which already have a Resource base of 16.7Mt at 8.9% ZnEq, including a high-grade component of 9.1Mt at 12.9% ZnEq.
Of course, as with all minerals exploration, success is not guaranteed — consider your own personal circumstances before investing, and seek professional financial advice.
This drilling extends the high-grade Fosters and Discovery Lenses and highlights the exceptional growth potential as the mineralisation remains open. The Discovery lens interval corresponds with the visible sulphide mineralisation previously reported.
The Discovery lens hole (DC18-79) intersection is the best result of all the historic holes drilled into the Discovery lens. Here’s DC18-79 drill core showing massive sulphide mineralisation from 230.6 to 236.7 metres (756.5 to 776.5 feet):

This drilling represents a significant extension to the Dry Creek deposit and notably down dip at both the Fosters and Discovery lenses. These first two extension drill holes highlight the upside potential for a significant expansion to both the Resource grade and size at Dry Creek.
WRM Managing Director and CEO Matt Gill said “This drilling represents a significant extension to the Dry Creek deposit and notably down dip at both the Fosters and Discovery lenses. These first two extension drill holes highlight the upside potential for a significant expansion to the Resource at Dry Creek, both in terms of grade and size.
“Dry Creek is an exciting VMS deposit as it shows great variation in thickness that has the potential to rapidly add to the Resource. These current drill holes also highlight the potential for significant high-grade gold and silver with individual assays up to 25g/t Au and 1,795g/t Ag (or more than 50 ounces of silver per tonne in the old measure).
“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 143km2 land package.”
