THE DRILL SERGEANT: Cassini Resources (ASX: CZI) announced a new discovery at the company’s West Musgrave project (WMP) in Western Australia.
Cassini Resources said the discovery was made while conducting a program of resource extension drilling at the Nebo deposit within the WMP that is being funded as part of the Earn-in/JV Agreement the company has with OZ Minerals (ASX: OZL).
The JV partners are currently undertaking a Pre-feasibility Study (PFS) on the Nebo-Babel deposits as well as a regional exploration program.
The new high-grade lode position – to be known as that Angie Lode – was discovered by the PFS resource infill drilling, for which several holes had been designed to target potential high-grade extensions of mineralisation on the peripheries of the current Nebo resource.
Cassini has previously reported early success in this program at the H-T Lode at Babel.
The more recent program also targeted positions on the eastern margins of the Nebo deposit with success enjoyed from the first round of drilling.
The most successful of these was been drill hole CZD0084, intersecting:
50.35 metres at 0.62 per cent nickel, 0.54 per cent copper, 0.02 per cent cobalt and 0.15g/t PGE from 170.85m, including a high-grade core of 5.6m at 2.68 per cent nickel, 2.09 per cent copper, 0.09 per cent cobalt and 0.33g/t PGE from 186.95m.
In addition, drill hole CZD0082 returned:
58m at 0.32 per cent nickel, 0.37 per cent copper, 0.01 per cent cobalt and 0.12g/t PGE including 1.9m at 2.69 per cent nickel, 2.44 per cent copper, 0.07 per cent cobalt and 0.48g/t PGE from 202m, together with a broad zone of medium grade disseminated mineralisation.
Nearby holes CZD0080 and CZD0081 returned narrow, but high-grade intercepts of 0.15m at 1.47 per cent nickel, 0.06 per cent copper, 0.06 per cent cobalt and 0.11g/t PGE from 195.3m and 0.75m at 1.40 per cent nickel, 0.50 per cent copper, 0.05 per cent cobalt and 0.23g/t PGE from 263.75m respectively, representing potential strike continuity of at least 550m from CZD0084 through to CZD0081.
Cassini noted that historically there has been a lack of drilling carried out in the south-eastern and eastern margins of Nebo.
Because of this, the south-eastern area was targeted after detailed modelling of Downhole Electromagnetics (DHEM) from the 2017 drill program identified conductive plates that had not been adequately tested by drilling.
“Subsequent DHEM surveys have shown clusters of conductive plates surrounding CZD0082 as well as CZD0080 and CZD0081,” Cassini Resources said in its ASX announcement.
“There is no drilling between these zones and it remains a priority target for further extensional and infill drilling.
“Geological interpretation work on mineralisation controls on the Angie Lode are continuing.”
Cassini explained the high-grade Angie Lode results lie outside the current pit shell design, saying they can be reasonably expected to have a positive impact on future resource estimate and open pit mine optimisation updates.
Follow-up drilling will step 50m either side of CZD0082 testing the extensions of DHEM conductors along strike.
Further drilling is also planned to follow-up CZD084 once DHEM is completed on this hole.
