The Pole Star showing is situated between the Silver Cup mine (MINFILE 093M 040) and Nine Mile Mountain peak, 14 kilometres northeast of Hazelton.
The main vein is exposed for approximately 30 metres along the face of the bluff. It ranges from 15 to 60 centimetres in thickness and strikes 330 degrees, dipping 15 degrees southwest. It has been prospected by a short adit and a trench. Galena and sphalerite and lesser tetrahedrite and arsenopyrite have been identified.
The hostrocks are interbedded greywacke, sandstone and argillites of the Middle Jurassic to Lower Cretaceous Bowser Lake Group, which strike 210 degrees and dip 15 degrees east.
The first discovery of silver-lead-zinc ore containing antimony was made on Nine Mile Mountain in 1908. In the years that followed, numerous other mineral-bearing veins were discovered in the area. Between 1910 and 1913, small shipments of high-grade silver-lead ore were made from 15 properties.
In 1974, Spectrum Industrial Resources Limited held the area immediately east of the Pole Star showing as the Beta property. That year, Daniel Basco of Nordic Mining Services conducted a geological reconnaissance of the Beta claim group.
In 1980, Short Staun Minerals Corporation conducted a program of regional geological mapping and prospecting over the Cup claims to the immediate northeast of the Pole Star property.
The ground apparently lay dormant until 2005, when Cadre Capital Incorporated staked new claims over the Nine Mile Mountain area and the Sidina Creek area to the north as part of their Hazelton project. The following year, Golden Sabre Resources optioned the claims and carried out a limited exploration program of rock sampling and soil grid geochemistry. Between 2006 and 2012, the claims appear to have been dormant.
By 2012, TAD Mineral Exploration Limited (formerly known as TAD Capital Corporation) expanded their Sidina property to include additional claims covering the Nine Mile Mountain area to the south, formerly held by Cadre Capital. That year, Rio Minerals Limited conducted grid surveys and soil sampling near the Silverton occurrence (MINFILE 093M 038).
