Innouendy Nickel

Innouendy prospect (E09/2330)

The Innouendy prospect was first recognised by Aurora Minerals Ltd as potentially prospective for nickel and copper sulphides by the mapping of weathered ultramafic outcrops in 2010. These ultramafics were considered potential hosts for base metals and nickel and a total of 21 rock chip samples were collected. Several rocks anomalous in base metals assay were reported

A strong, discrete late time anomaly was detected by a VTEM survey (Versatile Time Domain Electromagnetics) This is coincident with a large magnetic anomaly. One possible interpretation is that the late time conductor is caused by sulphide mineralisation that has pooled within a mafic or ultramafic intrusion. The discrete magnetic anomaly may define the boundary of the intrusion. The VTEM conductors were targeted directly by drilling and after later modelling of ground and downhole EM data.

Modelling of the DHEM in conjunction with ground EM was done by geophysical consultants Newexco. They confirmed the presence of two “category 1 conductors for immediate drill testing” and provided collar locations and attitudes of two holes to test them. Although 5 RC holes and a single diamond hole were drilled they did not target the centre of the modelled plates. No mineralisation or conductors were intersected in the holes.

Desert Metals believe the Innouendy prospect remains highly prospective for economic nickel copper mineralisation and that the conductive anomalies identified on 4 independent electromagnetic surveys remain untested. Airborne EM initially identified high amplitude, late time conductors while following up on anomalous rock chip samples. These anomalies were subsequently confirmed by follow-up ground EM surveys. The conductors are hosted in ultramafic intrusive rocks on the margin of the Yilgarn craton.
