THE DRILL SERGEANT: Cassini Resources (ASX: CZI) has completed its first diamond drilling program at the company’s 80 per cent-owned Yarawindah Brook project in Western Australia.
The project is considered by Cassini to be prospective for nickel, copper, cobalt and platinum group elements (PGE’s).
Cassini Resources conducted the drilling to target multiple electromagnetic (EM) conductors it had identified following airborne and ground EM surveys in 2018.
The latest drilling returned encouraging nickel and copper results from a total of nine diamond holes – YAD0004 through to YAD0006 at the AN02 conductor, now re-named the Avena prospect, and YAD0003, at the Brassica prospect.
Drilling at Avena predominantly intersected broad zones of shallow, disseminated nickel and copper sulphides, and locally contain high-grade, massive nickel sulphides.
Cassini declared it was encouraged by a massive sulphide intercept of:
0.12 metres at 5.97 per cent nickel, 0.75 per cent copper, 0.39 per cent cobalt and 2.66 grams per tonne PGE from 84.3m.
“Nickel tenor of this intercept is representative of the historical massive sulphide intersections at Yarawindah, which are the Company’s primary targets,” Cassini Resources said in its ASX announcement.
“Although thin, this interval is interpreted to represent a structurally remobilised massive sulphide from a proximal source.
The company was also heartened by an encounter from:
5.05m at 0.69 per cent nickel, 1.17 per cent copper and 0.06 per cent cobalt from 57.95m.
“These intercepts range from 50m to 72m vertically below surface, well within open-pit mining depths,” Cassini observed.
At the Brassica prospect, YAD0003 intersected a 70m zone of metagabbro, similar to previous drilling results, with thick zones of disseminated and locally semi-massive zones of barren iron sulphides (pyrrhotite) and trace copper sulphides (chalcopyrite) reflecting low tenor nickel and copper sulphide mineralisation.
“The results to date at the Avena and Brassica prospects support the company’s exploration model that the Yarawindah project has potential to host multiple nickel-copper magmatic sulphide deposits,” the company said.
