Classic Minerals records bonanza 592g/t gold hit at Kat Gap

Classic Minerals ASX CLZ drilling Kat Gap high grade gold deep infill
Classic Minerals plans to begin a deeper drilling program at Kat Gap next month to test extensions to known mineralisation.

Aspiring producer Classic Minerals (ASX: CLZ) has recorded a 592 grams per tonne gold bonanza intercept from infill reverse circulation drilling at its flagship Kat Gap project near Southern Cross in Western Australia.

The April campaign saw the company drill 28 holes for a total 2,548m, including a single shallow hole for 40m, with results delivering significant zones of high-grade gold mineralisation.

The single hole was drilled for the purpose of advanced metallurgical studies and returned a result of 10m grading 40.54g/t gold from 26.5m, including 0.5m at the bonanza 592g/t from 28.5m.

The hole was close to existing high-grade gold holes which have previously returned 9m at 15.21g/t from 22m, and 10m at 30.78g/t from 28m.

Other assays returned from the infill campaign were 4m at 18.97g/t gold from 76m, including 2m at 33.75g/t from 77m; 4m at 16.93g/t gold from 101m, including 1m at 58.40g/t from 101m; 6m at 7.72g/t gold from 78m, including 1m at 26.20g/t from 83m; and 6m at 5.30g/t gold from 84m including 1m at 17.40g/t from 88m.

Also recorded was 5m at 7.95g/t gold from 103m, including 1m at 24.90g/t from 107m; 2m at 10.73g/t gold from 74m, including 1m at 19.90g/t from 74m; 2m at 10.30g/t gold from 100m, including 1m at 10.60g/t from 101m.

Focus areas

Classic’s infill program was conducted on a 10m square and 20m by 10m grid and focused on an area between 20m to 120m north of the cross-cutting Proterozoic dyke.

It was designed to test an artificially-created gap between earlier shallow reverse circulation holes which tested the oxide profile and much deeper holes which tested the down-dip extent of the main granite-greenstone contact lode.

The company said if the gap could be filled in by zones of gold mineralisation, the project’s final optimisation work may result in deeper pit designs to allow for access to more mineable gold-bearing ore.

Deeper drilling

Classic will head back to Kat Gap next month to conduct deeper drilling down dip and down plunge of the current inferred resource.

That program will comprise up to 15 holes ranging in depth from 150m to 200m for a total of approximately 2,200m of drilling.

The follow-up work will be “urgently undertaken” to enable the new gold intersections to be incorporated into the current resource model for Kat Gap.

Once this is complete, further optimisation work will be carried out and combined with recent bulk sampling results to aid in the final pit design.
