Final assays from a drilling program by Kairos Minerals (ASX: KAI) at its 100%-owned Roe Hills gold-nickel-cobalt discovery in regional Western Australia have shown widespread shallow gold mineralisation over multiple areas, confirming its status as a substantial emerging greenfields asset.
The 5115 metre reverse circulation drilling program, completed earlier this year, confirmed significant extensions to previously-identified gold mineralisation zones at the Terra, Caliburn and Lingering Kiss targets.
Lingering Kiss is located at the southern strike extension of the French Kiss gold deposit, owned by Silver Lakes Resources and scheduled for production in 2019 (ASX: SLR).
Kairos reported the majority of successfully-completed holes intersected gold mineralisation “over significant widths and good grades”.
At Lingering Kiss, where eight holes were completed for a combined total of 1350m, drilling was designed to test for dip and strike extensions of previously-defined mineralisation and to confirm the orientation of main gold-bearing structures to assist follow-up drill targeting.
All holes drilled to target depth intersected significant mineralisation, with better results including 9m at 2.29 grams per tonne gold from 123m; 1m at 3.39g/t gold from 125m; 2m at 7.13g/t gold from 128m; and 1m at 11.1g/t gold from 129m.
At the structurally-complex Caliburn target, a total of five holes were completed for 594m, with one hole (RHRC063) being “particularly encouraging”, having encountered the thickest zone of mineralisation identified to date, commencing just 10m below surface.
Best results from RHRC063 were 54m at 0.74g/t gold from 10m, including 16m at 1.02g/t gold from 22m; 2m at 6.43g/t gold from 54m; and 1m at 9.53g/t gold from 55m.
At Terra, located immediately north of Caliburn and referred to as a “completely blind” gold occurrence due to its lack of surface expression, a total of seven holes were completed for 1265m and one hole was extended for 70m, for a combined 1335m.
Best results were 35m at 1.05g/t gold from 96m, including 13m at 1.65g/t gold from 104m and 1m at 8.3g/t gold from 123m.
Drilling also identifies new drill-ready targets
Kairos’ drilling program also advanced Roe Hill project targets at Avalon, Nemo and Merlin, and identified multiple new drill-ready targets analogous to major gold deposits in the region including Karonie, French Kiss and Lake Roe.
The company said these targets were identified following a major reinterpretation of the geological, structural and geochemical framework of the 40 kilometre-long Roe Hills belt designed to assist with the targeting of potential key gold-bearing structures, particularly in areas where prospective basement sequences are obscured beneath transported cover.
Kairos is planning further drilling activities before year end to test priority targets and commence evaluation newly-identified anomalous trends and regional targets.
