Cassini Resources encounters broad zinc zones at West Arunta
THE DRILL SERGEANT: Cassini Resources (ASX: CZI) has received results from a recently-completed maiden drilling program carried out at the company’s 100 per cent-owned West Arunta project in Western Australia.
The drilling is the first ever drill program conducted for sedimentary zinc at the West Arunta project and targeted two ferruginous outcrops with the aim of testing for enriched zinc mineralisation in fresh bedrock beneath these outcrops.
According to the Cassini the drilling encountered broad zones of sub-surface enrichment in zinc and associated elements within the weathered zone at both Iapetus and Enceladus prospects.
Best results include:
WAC0007
22 metres at 0.26 per cent zinc from 13m, including 2m at 0.89 per cent zinc from 22m at the Enceladus prospect.
Anomalous zones of accessory metals were also intersected, including:
WAC0010
21m at 1.2 grams per tonne silver from 9m.
The company explained that all the zinc enrichment it intersected in the weathered zone sat within two main sub-horizontal layers.
Zinc-anomalous ferruginous-zones, which Cassini had originally hypothesized as gossans, were the target of drilling, and have now been reinterpreted to represent hydromorphic ferricretes.
Ferricretes are iron-rich accumulations that have been deposited in the regolith through the lateral movement of groundwater.
Cassini believes it to be very likely that zinc-rich ferricretes are the result of dispersion plumes from a proximal primary zinc mineralisation source as most ferricretes in the area are not base-metal anomalous.
The company also finds the quantum of zinc anomalism and the presence of accessory metals such as silver to be very encouraging and point to a primary zinc sulphide source nearby.
“We are encouraged with the progress we’ve made from our maiden drilling campaign,” Cassini Resources managing director Richard Bevan said in the company’s announcement to the Australian Securities Exchange.
“The broad zones of zinc anomalism suggest a nearby source of bedrock zinc mineralisation.
“Furthermore, we have the tell-tale geochemical patterns that support our geological model.
“We have demonstrated that we are indeed in a brand new, sedimentary zinc province, that Cassini wholly controls.
“This program has been an important first step to finding an economic ore body.
“We now have the confidence to pursue our strategy and commit to more advanced exploration including geophysical surveys that we believe will provide vectors towards primary economic mineralisation.”
