White Rock Minerals Ltd (ASX: WRM) Dramatic intersection of high grade zinc drill holes, Alaska
Ballarat, September 28, 2021 AEST (ABN Newswire) – White Rock Minerals Limited (ASX: WRM) (OTCMKTS: WRMCF) is pleased to announce drill hole assay results from the Company’s 100% -owned Red Mountain VMS project for the first of the down-dip drill holes completed at the Dry Creek VMS deposit in 2021.
Drill hole DC21-97 tested the down-dip projection of the Fosters lens towards the western end of the deposit (Figure 1 *). The drill hole intersected 1.4 meters of high grade massive sulphide grading 35% zinc, 12.2% lead, 237 g / t silver, 2.9 g / t gold and 0.3 % of copper. This suite of high grade polymetallic metals can also be summarized as a zinc equivalent content of 55.3% (ZnEq) or a silver equivalent content of 2,555 / t (AgEq).
– Spectacular high-grade massive sulphide intersected at the Dry Creek deposit of the Red Mountain VMS project in Alaska.
– Drill hole DC21-97 intersected 1.4 meters of massive sulphides grading 35% zinc, 12.2% lead, 237 g / t silver, 2.9 g / t gold and 0, 3% copper, for a zinc equivalent content of 55.3% (ZnEq), within a radius of 5.8 meters zone of mineralization grading 11.5% zinc, 3.4% lead, 69g / t silver, 0 , 8g / t gold & 0.1% copper.
– DC21-97 is more than 200 meters down dip of the nearest drill intersection, which contained 4.3 m at 4.8% zinc, 2.3% lead, 1,435 g / t silver, 2.2 g / t gold and 0.5% copper for 43.2% ZnEq, as previously announced. This recent drill hole now doubles the known depth of the resource in this area of ââthe deposit.
– Three additional drill holes have been completed at Dry Creek over nominal stretches spaced 200 meters apart along the strike of DC21-97 and assay results are awaited.
The massive sulphide zone is followed by a zone of stratified and banded sulphides in its lower wall, hosted in a dark gray to brown metamudstone typical of the Fosters lens. The overall zone of mineralization returned 5.8 meters at 11.5% zinc, 3.4% lead, 69g / t silver, 0.8g / t gold and 0.1% copper, for 17.2% ZnEq or 793g / t AgEq.
The intersection is 200 m down dip of the nearest drill hole, DC18-773, which was drilled in 2018 and returned an intersection of 4.3 m @ 4.8% zinc, 2, 3% lead, 1,435 g / t silver, 2.2 g / t gold and 0.5% copper for 43.2% ZnEq or 1,994 g / t AgEq.
The 2021 Dry Creek drill program.
White Rock completed four holes to test the depth extensions of the Dry Creek VMS deposit on 200 m steps down dip and along its one kilometer strike (Figure 2 *). Assay results for the three remaining drill holes (DC21-100, DC21-102 and DC21-103) are pending.
As previously reported, the second drill hole (DC21-1004) targeted the western end of the down-dip projection of the Fosters lens and intersected a zone of banded pyrite in the host carbon shale interpreted to be low. west along the direction of massive sulphide mineralization. cross-referenced in DC21-97. No significant base metal sulfides were recorded. The results of the assay are awaited.
Also as previously noted, the third drill hole (DC21-1025) intersected a series of large zones of pyrite dominated sulphide mineralization with less sphalerite (zinc), galena (lead) and chalcopyrite (copper). There are four zones interpreted to correlate with the Upper Fosters, Fosters, Copper Zone and Discovery lenses of the main Dry Creek VMS deposit (Figure 3 *). Significant base metal sulphides are restricted to narrow bands (10-30 cm) in the Discovery horizon. The results of the assay are awaited.
The fourth drill hole (DC21-103) successfully intersected the Fosters and Discovery sulphide horizons over 200 meters down dip from previous holes. A 5.5 m thick interval of pyrite-dominated stratified sulphides with less sphalerite and rare chalcopyrite and galena was intersected on the Fosters horizon. A 4.0 m thick interval of rolled to massive sulphides was intersected on the Discovery horizon. The Fosters sulphide horizon features typical fine-grained stratified sulphides hosted in black carbonaceous phyllites, while the Discovery sulphide horizon consists of semi-massive to massive stratified sulphides with visible sphalerite hosted at contact between meta-sediments and meta-volcanics. Semi-massive to massive sulphides with significant base metal sulphides are restricted to bands of 10-30 cm for the Fosters and Discovery intervals. The results of the assay are awaited.
The Dry Creek and West Tundra Flats (WTF) deposits of the Red Mountain VMS project already provide inferred mineral resources of 9.1 million tonnes at 157 g / t silver, 5.8% zinc, 2.6% lead and 0.9 g / t gold for a grade of 13.2% ZnEq, or 609g / t AgEq. Of this total, the Dry Creek deposit contributes an inferred mineral resource of 2.4 million tonnes grading 69 g / t silver, 4.7% zinc, 1.9% lead and 0.4 g / t gold for a grade of 8.8% ZnEq, or 406 g / t AgEq.
