55km2 in the Fraser Range along strike from the Nova-Bollinger Mine (Independence Group) and Mawson discovery (Legend Mining)
Historic drilling indicates mineralisation in shallow oxide, including:
16m @ 0.60% Ni, 0.14% Cu and 0.13% Co and
20m @ 0.57% Ni, 0.17% Cu and 0.08% Co
Opportunity to locate the sulphide source of previously drilled near-surface oxide intersections
The Gnama Nickel Project is located at the southern end of the Fraser Range, host to numerous recent nickel discoveries including Nova-Bollinger, acquired by IGO for $1.8 billion in May 2015. Renewed interest has been fuelled by Legend Mining’s Mawson discovery in January 2020 with recent drill intersections including 12.8m @ 2.8% Ni, 1.4% Cu and 0.14% Co from 235m.
Both Nova Bollinger and Mawson were identified by an anomalous Ni+Cu signature at surface with Ni sulphide source at depth. Typically, discoveries have a significant barren zone between the oxide cap and sulphide source with primary mineralisation at Nova occurring up to 450m beneath the surface.
Gnama was identified by Sirius Exploration in 2010 when RC holes drilled to test a soil geochemical anomaly intersected a zone of Ni, Cu and Co enrichment in the oxide zone above mixed mafic and ultramafic rocks. Drill hole SFRC5 intersected 16m @ 0.6% Ni, 0.14% Cu and 0.13% Co from 36m and drill hole SFRC6 intersected 20m @ 0.57% Ni, 0.17% Cu and 0.08% Co from 28m. Sirius remarked that “Whilst the elevated levels of Ni and Co could be explained by lateritic enrichment, the presence of copper suggests that the underlying rocks may contain sulphide mineralisation.” However, as Sirius moved on to drilling at the Nova target this potential was never followed up and the tenement was allowed to lapse.
