Hele Project HTX Minerals-Impala Platinum JV– (PGE-Ni-Cu)
MCR Region, ON
- Large MCR aged ultramafic intrusion hosted in Sibley sediments
- Geochemistry, age, setting and host rocks are very similar to known ultramafic hosted (Eagle-Tamarack-Current Lake) type deposits
The Hele property is located in north-western Ontario, approximately 75 km north-east of Thunder Bay and 15 km west of Nipigon, roughly 5km north of the Trans-Canada Highway. The property consists of 63 claims (962 units) in Hele, Stirling, McMaster and Anders Township, all 50% owned by HTX Minerals Corp.(HTX) and 50% owned by Impala Platinum Holdings Limited (Implats).
The property is underlain by the Hele Intrusive Complex: a composite ultramafic-mafic sill dike hybrid funnel-like body of similar rock type and geochemistry to the Seagull-Disraeli (Minfocus) and Thunder Bay North (Panoramic Resources) intrusive complexes. This more primitive magmatic suite likely includes the intrusives hosting the recent Ni-Cu-PGE discoveries by Kennecott-Rio Tinto at Tamarack in Minnesota and Eagle in Michigan (~4.05 Mt @ 3.57% Ni, 2.91% Cu, 0.10% Co, 0.73g/t Pt, 0.47g/t Pd and 0.28g/t Au).
The Hele Intrusive Complex is a zoned picritic intrusion of peridotite and olivine-gabbro, approximately 8 by 8 km in size, that intrudes flat-lying to shallow dipping, red shales and siltstones of the Sibley Group. The intrusion likely extends to the west and north under the sediments and along the Black Sturgeon Fault as indicated by the magnetic data. The Complex is situated immediately southwest of the Black Sturgeon Fault Zone and stands out in marked topographic relief compared to the surrounding softer and recessively weathering sediments.
HTX and Implats have been actively working on the Hele Property from 2009-2013. During this time a mapping and prospecting program has been completed as well as an airborne VTEM survey, ground gravity survey, Soil Gas Hydrocarbon surveys and a ground EM survey. In addition, a 2,326m (10 hole) drill program was completed across the property..The focus of these programs was to investigate for magmatic sulphides related to the Hele Intrusion as well as to gain a better understanding of the geology and distribution of the Proterozoic Hele Intrusion.
Although no significant mineralization or deeper feeder features have been intersected to date, the favourable geology and size of the intrusion suggests the prospectivity of the intrusion for hosting PGE-Ni-Cu mineralization in a feeder or chonolith remains high. HTX and Implats are currently reviewing the work completed to date and are deciding on an apppropriate plan to further advance the Hele property.
