The Strickland project is located 200km north of Southern Cross in Western Australia. The tenement area covers portions of four Archean greenstone belts (Evanston, South Elvire, Mount Manning and Yerilgee), separated by Archean granitoids and gneisses within the Southern Cross Province of the Yilgarn Craton (c. 3.6-2.63 Ga). The Southern Cross Province is separated from the Eastern Goldfields Superterrane to the east by the Ida Fault.
Previous work has been focussed on the major banded iron formation that transects most of the tenement position from north to south and the potential for orogenic gold, including by Arrow Minerals.
Recently Arrow completed analysis of the significant volume of existing stream sediment, soil, AC and RC multielement geochemistry. The analysis resulted in the recognition of a suite of highly anomalous elements typical of volcanogenic massive sulphide (VMS) copper-gold systems.
The notable absence of graphitic units seen in cuttings or outcrop, and the rhythmic interbedding of basalts, ultramafics, rhyolites and sediments seen during a recent field visit is highly encouraging in terms of indication of the VMS environment. Discrete zones of anomalous Cu alerted us to the potential base metals at Strickland.
Arrow completed airborne electromagnetic surveys of five of the most prospective parts of the project, and subsequently completed reverse circulation drilling of seven holes and associated downhole electromagnetics (DHEM) to detect conductive mineralisation away from the drillholes.
At drillhole STKV009 the DHEM survey confirmed the presence of two distinct zones of conductance. The first, Plate 1, 50m long and 50m wide with a conductance of 150 Siemens. The second, Plate 2, 300m long and 100m wide, with a conductance of 1000 Siemens.
Assay results returned from samples collected at STKV009 highlighted a zone of elevated copper, 20m at 0.22% Cu, from 120m downhole. The anomalous copper zone is in close association with the modelled DHEM conductor Plate 1. This confirms the conductance response is related to copper sulphides.
Arrow is now evaluating the Strickland Project land package to identify similar coincident geochemical and geophysical signatures that would form the basis for the next phase of work. When completed Arrow will rank and prioritise all targets available to the Company to ensure resources are deployed to advance the highest ranked targets with priority.
