White Rock's 2019 program remains on track
White Rock Minerals Ltd (ASX:WRM) today provided an update on its work at the globally significant Red Mountain high-grade zinc and precious metals VMS project in central Alaska – otherwise known as the Red Mountain Project.
White Rock reminded the market this morning that there are already two high grade deposits at the Red Mountain Project, with an Inferred Mineral Resource of 9.1 million tonnes @ 12.9% ZnEq for 1.1 million tonnes of contained zinc equivalent at Dry Creek and WTF.
The company’s summer field exploration activities have focused on defining and drill testing new targets that could yield a significant discovery to support a greenfield development scenario.
This back half of 2019, has seen White Rock focus its drilling on three new target areas: Arete, Smog South and Sheep Rogers.
The Arete and Sheep-Rogers target are within an extensive alteration zone with 10km of strike, where multiple prospective occurrences containing sulphide accumulations, chert and iron formations have been identified. These are all believed to be proximal to horizons prospective for base metal rich massive sulphides along strike and down dip.
The Smog South prospect is a large isolated target area further east along the Glacier Trend also with extensive alteration, anomalous geochemistry plus surface base metal mineralisation within a VMS horizon at the Smog prospect to the north.
WRM also has its drill sights on further target areas including Artesia, Irish Knob, Black Top, Grizzly, Kettle and Glacier Creek East. All target areas, including those drilled recently with only one hole at each, contain numerous prospective horizons, geochemical anomalies and EM conductivity features to be drill tested.
This drilling has provided important stratigraphic information.
White Rock has also focused on acquiring new regional surface geochemistry across the expanded tenement package and the intervening prospective stratigraphic package to the south and west.
A sampling survey was completed with >1,000 samples collected over the 800km2 area extending from Sheep Creek in the west through to Anderson Mountain in the south and West Fork to the east. Historic VMS occurrences here led to WRM expanding its strategic tenement package from 143km2 to 475km2 in late-2018
Assays for 18 samples here averaged 5.6% Zn, 1.7% Pb, 49g/t Ag & 0.5% Cu3.
Here’s a look where WRM is conducting its activities:
The current program has seen WRM drill 11 holes with mixed results, however drilling at Dry Creek is now targeting the down-dip projection of mineralisation 200 metres deeper than previously drilled. Should a successful drill test provide a significant step-out from the known high-grade Resource, it will help illustrate the upside size potential of the Dry Creek deposit and underpin the potential of the project for further development studies.
This suggests there is still plenty of work to do and therefore further, potentially positive news to come.
