A drilling campaign over high-priority gold and nickel targets has been completed at Kairos Minerals’ (ASX: KAI) wholly-owned Roe Hills project, east of Kalgoorlie in Western Australia.
Drilling contractor Ausdrill managed the job, which comprised 20 holes for 2,992m and tested for mineralisation at the Caliburn (gold), Talc Lake (nickel) and Black Cat (gold) prospects.
Drilling at the first two prospects returned broad visual zones of silica-carbonate and epidote alteration, including 2m of significant nickel sulphides from 99m at Talc Lake.
The same hole targeted the up-plunge position of historical diamond drill intercepts, including 1m at 3.53% nickel from 155m, and tested the basal ultramafic unit to 261m depth.
The hole has been PVC-cased and is awaiting a down hole transient electromagnetic (DHTEM) survey expected within the fortnight.
Drilling at the Black Cat target was designed to test a consistent 1.1km-long, gold-in-soil anomaly defined from a geochemistry program conducted last year.
One of those holes intercepted a broad zone of sulphides from 99m, with significant sulphide content also returned from 99m to 116m, and from 146m to 154m.
Executive chairman Terry Topping said forthcoming assays would provide an important assessment of the three high-priority targets.
“Although the results are about seven weeks away, our visual analysis of the [reverse circulation] chips indicates plenty of exciting potential, particularly at Black Cat where we can see broad zones of significant sulphides,” he said.
Meanwhile, Kairos is continuing work on an Ultrafine+ soil geochemistry program at Roe Hills, with approximately 1200 samples collected from the Caliburn and Talc Lake areas, as well as prospective areas further to the north, south and east.
The sampling technique was developed by CSIRO (Commonwealth Scientific and Industrial Research Organisation) to explore areas under transported cover.
It is expected to allow for the detection of geochemical anomalies over the margins of the salt lakes within Roe Hills.
The Roe Hills project comprises an extensive tenement portfolio with potential for significant discoveries of high-grade gold, nickel and cobalt mineralisation.
It is located in a structurally and geologically-complex area, adjacent to the regionally-significant Keith-Kilkenny Shear zone which is host to the Bombora gold discovery owned by Breaker Resources (ASX: BRB) and the Aldiss project (Silver Lake Resources, ASX: SLR).
Kairos’ tenure at Roe Hills adjoins the emerging Lake Roe gold discovery, also owned by Breaker Resources.
