The HB occurrence is located 14 kilometres northeast of Aiken Lake and 101 kilometres almost due north of the community of Germansen Landing.

The Star property showings such as the HB zone occur within the Lower Jurassic Polaris Ultramafic Complex which is composed of dunite, werhlite, pyroxenite, and gabbro, some of which is altered to serpentine.

The HB (Haslinger B) zone is located on a southwest trending ridge that is underlain by layers of peridotite, olivine clinopyroxenite and pyroxenite which have a northeast dip. Disseminated chalcopyrite and pyrrhotite have been identified.

Historic sampling results are reported to include values up to 0.305 per cent copper, 1.320 grams per tonne platinum and 1.822 grams per tonne palladium (Assessment Report 35680).

In 2004, one value obtained from the olivine clinopyroxenite was 0.024 per cent copper, 0.28 gram per tonne platinum, and 0.368 gram per tonne palladium (Assessment Report 27617). Other samples have yielded up to 0.06 per cent copper. A grab sample (STJ-05-37) obtained during 2014 exploration at HB returned values of 0.31 per cent copper, 0.3 gram per tonne platinum and 0.31 gram per tonne palladium (Assessment Report 35114).

Work History

In February 1995, the Star 1-5 claims were staked by U. Mowat to cover a unit of the Polaris 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 (PGE) 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 NQ holes on the HC (094C 166) and GL (094C 165) zones totalling 1044 metres. In 2005, the Star claims were briefly optioned to Aumega Discoveries, but the option was terminated. In 2007, U. Mowat collected 32 rock samples and 3 soil samples.

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, 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 (Assessment Report 35114). In 2015, U. Mowat completed a further program of geochemical (rock and soil) sampling on the Star property (Assessment Report 35680). These programs resulted in anomalous copper, nickel, cobalt, platinum and palladium values at mineral occurrences across the property.

A small prospecting, rock and soil sampling and drone imagery survey was conducted primarily on the HB, Ridge and GL mineral occurrence areas in 2022 by tenure holder Granite Creek Copper Ltd (Assessment Report 41145). Further soil and rock sampling was conducted by Granite Creek Copper in 2024, and several samples of nickel, copper and platinum group elements were sent to laboratories for pilot-scale testing aimed at enhanced metal extraction with a high level of carbon sequestration through carbonation of magnesium minerals (Press Release, Granite Creek Copper Ltd., Feb. 5, 2025).
