Vancouver — Junior
Hole 21, collared 120 metres of the discovery hole, cut 13.5 metres averaging 1.4 grams combined platinum-palladium at a down-hole depth of 121.5 metres. Included in this section was a higher-grade portion running 3.2 grams platinum-palladium over 1.5 metres.
The results are even better than hole 2, which returned 1.4 metres of 2.1 grams combined platinum-palladium. Both holes were collared in a transition zone between ultramafic and mafic layers, which stretches for 5 km in strike length.
The platinum-palladium mineralization is hosted by a cumulate layer of coarse-grained plagiocase formed at the ultramafic-mafic interface of the intrusive complex. This is similar to the JM Reef of the Stillwater complex in Montana.
Based on the discovery, Aurora plans to define the target using ground geophysical techniques. Drilling will follow.
In addition to the reef targets, Aurora has identified high concentrations of vandium in semi-massive-to-massive magnetic layers at the base of the Lansdowne House layered complex. Hole 10 cut several intervals from 126 to 178 metres down-hole, grading 0.16-0.82% vanadium pentoxide.
The hole is still being sampled, and geophysics suggest the layers may continue for a strike length of 10 km.
Aurora notes that the results are similar to the average grade of vanadium deposits in South Africa and Australia: 0.47-1.4%.
