Other Targets

In addition to Nebo-Babel and Succoth, the West Musgrave Project offers a number of other early-stage but highly prospective exploration targets with known mineralisation. These include the Esagila, One Tree Hill and Yappsu nickel-copper targets.

Esagila is the second most advanced nickel prospect within the Succoth-Esagila complex and is the best massive nickel sulphide intersection explored outside of the Nebo-Babel deposits since the Company acquired the Project in April 2014. Located only 4km from Succoth, both prospects have been interpreted as part of the same mineralised intrusive complex that covers approximately 65km2. Mineralisation at Esagila has so far been defined over a strike length of 1,300m. Drilling conducted mid-2015 of CZD0010 returned 1.1m @ 0.70% Ni and 0.95% Cu from 360.3m within the massive sulphide zone.  The prospect remains relatively under-explored, with the intrusion only effectively tested by 6 diamond drill holes, leaving enormous scope to discover high-grade copper and nickel-rich mineralisation between the existing drill holes and/or at the down-dip and down-plunge extensions.

The One Tree Hill prospect is located at the south western end of the West Musgrave project, about 13km SW of Babel, and is associated with a major regional structural intersection. Historically, only two holes had tested a surface EM anomaly identified by previous explorers with encouraging results of 0.4m @ 2.62% Cu from 152.6m, with significant Platinum Group Element (PGE) anomalism of 35m @ 0.11g/t Pt+Pd intersected. Cassini completed its first hole CZD0008 at the One Tree Hill Prospect in 2015 and intersected significant copper mineralisation over short intervals within a broad alteration zone. Significantly, down-hole electromagnetic (DHEM) survey identified an off-hole conductor, approximately 30m by 30m at 350m with an extremely high modelled conductance of >100,000S suggesting massive sulphides. In November 2016, Cassini drilled hole CZD0017 targeting this prospective conductor and intersected a 15m zone of mineralisation with 3m of massive sulphide, containing approximately 5-10 volume % chalcopyrite (copper sulphide) amongst pyrrhotite (barren iron sulphide). Based on existing data, the mineralisation appears to be associated with Giles-age gabbroic rocks, which are interpreted to host Succoth-style, most likely Cu-rich magmatic sulphides that may form part of a larger mineralised system at One Tree Hill. It is anticipated that assay results for CZD0017 will be available mid-January 2017. A DHEM survey is planned for 2017 and a follow-up work plan following interpretation of existing and new data.

Cassini is in the process of prioritising these targets for future testing, while remaining focussed on the development of the Nebo-Babel Project.
