The Lonestar showing is located on the south slope of Wilauks Mountain, 4.25 kilometres due east of Alice Arm. In 1918, the area was explored for gold.

The region is underlain by an assemblage of volcanics and sediments comprising the Upper Triassic Stuhini Group, the Lower Jurassic Hazelton Group and the Middle Jurassic to Upper Cretaceous Bowser Lake Group. This assemblage has been folded into a north-northwest trending anticline (Mount McGuire anticline) and regionally metamorphosed to greenschist facies.

The showing is hosted in Stuhini Group argillite near the contact with augite porphyritic basaltic flows which are situated on the western limb of the Mount McGuire anticline. A quartz vein, up to 7.6 metres wide, contains bands of white quartz and strikes north- northeast for 460 metres. Mineralization consists of pyrite, minor arsenopyrite and sphalerite. A grab sample from the dump of an adit assayed low values in gold and silver (Minister of Mines Annual Report 1918, page 68).

Across a small creek from the adit, quartz stringers mineralized with galena and sphalerite are found cutting schistose argillite. The argillite strikes 030 degrees and dips 75 degrees northwest.

In 1918, the claims covering the showing were owned by G.W. Morley et al. of Alice Arm. At an elevation of 213 metres a tunnel has been driven across a 7.6 metre vein of grey quartz. The vein has about the same strike as the Silver Bell vein below (103P 154), but is a different vein.
