WA-focused gold exploration and development company Classic Minerals Limited (ASX. CLZ) reports that RC drilling at the Kat Gap project continues to deliver significant zones of gold mineralisation.
The company has now received assays results from its most recent RC drilling programme of 23 holes for 1,449m at the Kat Gap, which lies near its Forrestania Gold Project (FGP) in Western Australia.
Classic CEO Dean Goodwin said the recent drilling at Kat Gap showed that broader zones of flat supergene gold mineralisation project sit well out into the granite around 100m from the main contact south of the cross-cutting Proterozoic dyke.
“This latest round of drilling has shown that significant high-grade gold can still be intersected at shallow depths well north of the Proterozoic dyke.
I’m very pleased with these results as it demonstrates the strength in the system to the north. It’s not slowing down by any stretch.
“We need to keep going north obviously but drilling deeper needs to be conducted as well. It’s still early days and we have a relatively broad drill spacing up the northern end but at this stage it’s looking really good.
“We also drilled a single line of RC holes on the southern side of the Proterozoic dyke 60m south of previous RC holes conducted by Classic over a year ago.
“We hit a broad 10m thick zone of supergene gold mineralisation well out into the granite which we weren’t expecting. That’s telling us that there’s probably something substantial lurking out in the granite itself well away from the granite-greenstone contact. It’s very exciting.”
This round of RC drilling at Kat Gap was focused on testing the northerly and southerly strike extensions along the granite-greenstone contact plus some infill drilling between existing 40m spaced sections. System remains open in all directions.
Gold mineralisation now extends over 600m in strike with significant gold intersected on both sides of the Proterozoic dyke. Classic has only drilled a handful of holes on the southern side with the strike wide open further south.
Better results from the most recent drilling include: 3m grading 62.10 grams per tonne gold from 36m; 4m grading 8.48 grams per tonne gold from 50m; 3m grading 5.87 grams per tonne gold from 36m; 1m grading 9.64 grams per tonne gold from 19; 13m grading 2.05 grams per tonne gold from 25m; and 10m grading 1.48 grams per tonne gold from 24m.
Kat Gap is strategically located approximately 70km south-south east of the company’s Forrestania Gold project containing the Lady Magdalene and Lady Ada gold resources.
Mr Goodwin said the next few rounds of RC drilling at Kat Gap will focus mainly on testing the main granite – greenstone contact further north and south along strike from the current drilling area. The next RC drilling programme will test the northerly and southerly extensions for another 100-200m along strike.
RC Drilling will also test the extent of the recently discovered supergene horizon south of the Proterozoic dyke out in the granite. Further drilling will be conducted to determine the source of this new supergene zone.
RC drilling programmes will also be carried out in the granite to test the large 5 km long geochemical anomaly identified in previous historical auger soil sampling. The initial program will focus around the cross-cutting Proterozoic dyke where high auger values were returned along with a dilational site located in the north-eastern most area of the geochemical anomaly.
Historical RC drilling at Kat Gap is mostly on 100m – 200m line spacings. There is strong potential for additional mineralisation to be identified up-dip, down-dip and along strike, both outside of and within the existing historical RC drill coverage.
