The Toronto-based company resampled a hole that was drilled in the 1980s by Atomic Energy of Canada to test the intrusion’s suitability as a disposal site for nuclear waste. Another three holes are being re-evaluated.
The hole defines two platinum-palladium-rhodium-gold layers in a basal anorthosite unit. Within layer A, 6.5 metres (from 361 to 367.5 metres) averaged 1.86 grams of those combined metals per tonne, including a higher-grade core. Immediately below that, 79.8 metres (372.2-452 metres) averaged 0.27 gram combined metals, including 33.1 metres of 0.34 gram.
The results are similar to those obtained in seven short holes drilled earlier this year by Mustang. Those holes were drilled to a depth of 150 metres and collared 1.5 km to the east.
Geologically, East Bull Lake is a gabbroic-anorthositic, inward-dipping lopolith that measures 22 km long, up to 5 km wide and 1 km thick. Mustang’s claims cover more than 90% of that.
Mineralization in the basal anorthosite is of the “contact-type” described in several reports published by the Ontario Geological Survey. This variety consists of disseminated-to-clotty magmatic pyrrhotite, chalcopyrite, pyrite and minor pentlandite enriched in, or proximal to, palladium-bismuth-tellurium compounds and sperrylite.
In related news, Mustang has changed its name to Mustang Minerals and tied up 8,528 ha of ground near the River Valley intrusion, 50 km east of Sudbury.
The name was changed in accordance with an agreement with Capital House Canada, which saw the company take over a subsidiary of that unlisted company (T.N.M., Jan. 18/99).
