Classic Minerals reports more high-grade gold intercepts from drilling at Kat Gap project
Classic Minerals continues to build confidence in Kat Gap gold deposit with more high-grade and broad intercepts.
Western Australia explorer and developer Classic Minerals (ASX: CLZ) has reported further high-grade gold intercepts from infill drilling at its flagship Kat Gap project, 170km south of Southern Cross in WA.
The latest assays come from a large 109-hole for 7,110m program underway at Kat Gap.
During July and August, 24 holes were completed for 1,445m.
Latest assays are from 14 holes that were drilled immediately south along strike of the first 10-infill holes that were reported at the start of the month.
Best results from this latest assay batch were 2m at 21.07 grams per tonne gold from 33m, including 1m at 40.1g/t gold from 33m; 2m at 17.2g/t gold from 53m, including 1m at 19.9g/t gold from 53m; and 2m at 7.1g/t gold from 57m.
Two notable broader intervals were 10m at 3.8g/t gold from 50m, including 1m at 24.1g/t gold from 50m; and 10m at 2.74g/t gold from 70m, including 1m at 18.6g/t gold from 79m.
Classic confirmed 85 drill holes totalling 5,665m of the 109-hole program remain to be drilled.
The 109-hole drilling program at Kat Gap covers 100m to 300m north along strike of the cross cutting Proterozoic dyke, as well as 200m north along strike from the recent bulk sample mining operation.
Bulk sample mining operation
The closer spaced infilling drilling comes as a result of the company’s recent bulk sample mining operation.
A slight swell and pinch in the ore zone was exposed over short wavelengths of around 10-15m, which resulted in drilling a minimum of 10m spaced sections and 10m spaced holes on the section to gain greater confidence in the resource model.
The new spacing aims to convert resources from inferred to indicated – generating a higher level of confidence for final pit design work.
Additionally, the infill program will reduce the number of grade control holes required in pit once mining is underway.
Most of the drilling reaches shallow depths of between 40-70m; however, deeper holes to 100-140m will be completed to extend the known gold mineralisation down dip.
Classic is optimistic this work will add additional mineable ounces and a potentially larger final open pit design.
The 109-hole program is expected to wind-up within six weeks, with results to be released to the market as they become available.
