The Jewel Box occurrence is located approximately 8.3 kilometres northeast of Aiken Lake and approximately 97 kilometres northwest of the community of Germansen Landing.

The area is underlain by the Lower Jurassic Polaris Ultramafic Complex which is composed of dunite, werhlite, pyroxenite, and gabbro, some of which is altered to serpentine.

The pyroxenite of the Jewel Box zone is mineralized with coarse-grained pyrite and chalcopyrite which can form up to 40 per cent of the rock. The Jewel Box sulphides are geochemically distinct from the Queen zone (094C 163), the GL zone (094C 165), the Haslinger zones (094C 166, 167, 168) in that they are highly anomalous in cobalt and silver.

Work History

The Star 1-5 claims were staked by U. Mowat in February, 1995 to cover a unit of the Polaris Ultramafic Complex. Mowat prospected, sampled and mapped the property from 1995 to 2002 inclusive. In 2003, Minterra Resource Corp. optioned the Star magmatic platinum group element property from Mowat. The company proceeded with an 8-line kilometre induced polarization survey that identified a number of drill targets. In 2004, Minterra drilled eight holes on the property totalling 1044 metres. The Star claims were briefly optioned to Aumega Discoveries in 2005 but the option has been terminated. The best values obtained from the Jewel Box zone were reported at 0.27 per cent copper, 0.094 gram per tonne platinum and 0.084 gram per tonne palladium (Assessment Report 27617).

In 2010, U. Mowat completed geochemical sampling (44 rock, 52 soil, 1 silt) on the Star property which cover parts of the HA, HB, Taurus and Libra zones (094C 167, 168, 169). In 2014, U. Mowat conducted geochemical sampling (110 soil, 190 rock) on the large Star property which covers the Queen (094C 163), GL (094C 165), Ridge (094C 164), HC (094C 166), HA (094C 167) and HB (094C 168) occurrences.

In 2015, U. Mowat completed a further program of geochemical (rock and soil) sampling on the Star property. A rock sample (37358) of listwanite hosting disseminated pyrite and chalcopyrite, taken approximately 650 metres north-northeast of the plotted location of the Jewel Box occurrence assayed 0.283 per cent copper, 0.098 gram per tonne platinum, and 0.154 gram per tonne palladium (Assessment Report 35680).
