ASX-listed Kairos Minerals is waiting for assays from a reverse circulation drilling program completed at its Roe Hills gold and nickel project about 120km east of Kalgoorlie in WA, however visual indications of sulphides in rock chips have management eager to move forward. The Perth-based company punched out 20 holes for an aggregate drilling coverage of 2,992 metres targeting gold and nickel targets at the project’s Caliburn, Talc Lake and Black Cat prospects.
According to Kairos, Caliburn and Talc Lake coughed up some broad visual zones of silica-carbonate and epidote alteration, indicating that it may be within cooee of the mineralised lodes, with one hole at Talc Lake returning 2m of significant nickel sulphides from 99m depth.
The Talc Lake hole was aimed at the up-plunge position of historical diamond drill intercepts, including one that went a grade of 3.53 per cent nickel over 1m from 155m depth.
It was also drilled down to 261m to test the basal ultramafic unit at Talc Lake.
Drilling at the Black Cat prospect was designed to test a consistent 1.1km-long gold-in-soils anomaly identified by Kairos’ geochemical program last year.
Hole RHRC120 intercepted a broad zone of sulphides from 99m, with significant sulphides content from 99m to 116m and from 146m to 154m.
An Ultrafine+ soil sampling program is also well advanced at Roe Hills, with about 1,200 samples already submitted for analysis.
The Ultrafine+ soil sampling technique has been developed by CSIRO to probe areas under transported cover.
Kairos says it hopes the technique will detect geochemical anomalies over the margins of the salt lakes.
Kairos Minerals Executive Chairman, Terry Topping said: “We expect to receive assay results within the next six to seven weeks, however, visual analysis of the RC chips indicates plenty of exciting potential, particularly at the Black Cat prospect where we can see broad zones of significant sulphides.”
“We’re also looking forward to results from the ongoing Ultrafine+ soil sampling program being conducted in partnership with the CSIRO, which has the potential to identify geochemical anomalies under areas of transported cover.”
The Roe Hills project area adjoins the emerging Lake Roe gold project owned by ASX-listed Breaker Resources.
Lake Roe hosts an open-pit and underground indicated and inferred resource of 27.9 million tonnes at an average grade of 1.5 grams per tonne gold for some 1.37 million ounces of contained gold.
