One Tree Hill Prospect
Since the last update in June, activities at One Tree Hill 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.
The aeromagnetic survey was flown at 30m height and 40m line spacing, providing very high quality data. The new magnetic data has been critical in the latest structural and geological interpretation of the prospect, particularly given that the Giles Mineralised Intrusions and Giles Metagabbros appear to be clearly defined in the magnetic images. Furthermore, the latest geological and structural interpretation on long-section correlates very closely with the interpretation of the magnetic data. This interpretation suggests that the mineralised intrusions at One Tree Hill are terminated against the Titan Fault to the southwest and are offset by the ENE trending Osborne Fault. Importantly, this indicates potential extensions of the Giles Mineralised Intrusions to the north of the existing drilling and to the south of the Osborne Fault, both of which remain untested.
Two RC drill holes have been completed for a total of 1,002m, stepping 200m east along strike from CZD0099 which returned several mineralised intercepts including 9m @ 2.56% Cu, 0.37% Ni, 0.06% Co & 1.32g/t PGE from 344m within a broader disseminated zone of 40m @ 1.16% Cu from 343m.
The latest 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 100m 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. Fold hinge zones are recognised as preferential positions within which massive sulphides may have accumulated and/or been preserved in metamorphosed and structurally complex mineralised systems. An interpreted fold hinge, west of CZD0099 therefore represents a priority target for further drill testing in 2020.
Succoth Deposit
Cassini reported a new geological interpretation at Succoth Deposit in
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.
An aeromagnetic survey was also flown over a relatively small block covering Succoth Deposit to assist with geological interpretation and targeting. The new magnetic data has helped to delineate existing mineralisation within a fault-bounded package of relatively magnetic lithologies. The east-west trending fault at the southern extent of Succoth has been intersected in sections XS-04 and XS-12. Although, mineralisation on those sections is truncated by the fault, it is not necessarily closed-off as some drill holes have interested mineralisation across the fault to the south. Mineralisation at Succoth remains open along a broad northeast-southwest trending corridor and potentially laterally. Broad drill hole spacing in particular to the north-east, means that further infill and extensional drilling could delineate zones of disseminated mineralisation broadly similar to those on section XS-20. The Company is continuing to evaluate the resource potential of Succoth and the impact it may have on Nebo-Babel development options.
