Cassini Resources Ltd (ASX:CZI) has received final results from recent drilling at One Tree Hill prospect and Succoth deposit within the West Musgrave Project (WMP) in Western Australia, signifying the completion of exploration programs for 2019.
Funded as part of the JV agreement with OZ Minerals Ltd (ASX:OZL), the drilling program has ‘significantly’ improved the geological and structural interpretation at One Tree Hill and supports new geological interpretation at Succoth for open-pit mining.
The JV partners are undertaking a pre-feasibility study (PFS) on the nearby Nebo-Babel deposits in conjunction with a regional exploration program across the WMP.
Plan of One Tree Hill drill collars over Reduced to Pole magnetics
Activities at One Tree Hill have comprised a high-resolution aeromagnetic survey and two reverse circulation drill holes testing extensions to mineralisation east of CZD0099, together with geological and geophysical modelling.
Two reverse circulation (RC) holes have been completed for 1,002 metres, stepping 200 metres along strike from CZD0099 which returned several mineralised intersections including:
- 9 metres at 2.56% copper, 0.37% nickel, 0.06% cobalt, 1.32 g/t platinum group elements within a broader disseminated zone of 40 metres at 1.16% copper from 343 metres.
Best of the latest results is 18 metres at 0.35% copper, 0.05% nickel and 0.38 g/t from only 52 metres in CZC0696, closer to the surface than previous intersections.
Geological and geochemical interpretation suggests the mineralised intrusions and country-rock are folded along an east-west trending fold plane.
The interpreted position of the fold hinge is approximately 100 metres to the west of CZD0099 and associated with a magnetic anomaly that is plausibly due to a higher abundance of magnetite and pyrrhotite within the mineralised units.
Succoth drill hole plan showing the relationship between recent drilling, mineralisation and structure
At Succoth, the JV has completed a further four diamond drill holes for 1,793 metres on two infill sections about 200 metres and 400 metres west of the first detail infill section.
The three sections now cover 400 metres strike extent of the deposit will drill hole spacing on the section line at 50 metres to 100 metres.
Best results are:
- 14.1 metres from 151.15 metres at 0.34% copper, 0.03% nickel and 0.09 g/t PGE;
- 89.5 metres from 319 metres at 0.68% copper, 0.07% nickel and 0.16 g/t PGE;
- 21.0 metres from 103 metres at 0.69% copper, 0.08% nickel and 0.08 g/t PGE;
- 1.5 metres from 62.5 metres at 1.01% copper, 0.15% nickel and 0.07 g/t PGE; and
- 21.0 metres from 309 metres at 0.36% copper, 0.03% nickel and 0.08 g/t PGE.
Results support geometry model
Results from the latest drilling support the folded geometry model at Succoth.
The latest geometry, if extrapolated across the currently defined strike extent of the deposit, has implications for the scale of the resource, resource extensions, potential mining strip ratio and further economic considerations.
Mineralisation remains open laterally, as well as at depth, and between broad-spaced drill holes outside of the three main drill sections.
The company is continuing to evaluate the resource potential of Succoth and the impact it may have on Nebo-Babel development options.
