The Last Chance (L.586s) occurrence is located between Mount McKinley and Franklin Creek, approximately 1.5 kilometres west of Burrell Creek.

The area is underlain by volcaniclastic and sedimentary rocks of the Carboniferous to Permian Harper Ranch Group, which have been intruded by granite and granodiorite of an un-named Middle Jurassic Intrusion. These are overlain by undivided volcanic rocks of the Eocene Penticton Group.

Locally, heavily altered meta-sediments and fine-grained siliceous volcanics host disseminated pyrite and galena mineralization. A select sample of dump material is reported to have assayed 9.2 grams per tonne gold and 239.4 grams per tonne silver (Property File - L. Lee [1989-11-01]: Summary Report - Burrell Creek).

Another zone of mineralization, referred to as the Jack zone, is located approximately 300 metres north- north east of the Last Chance workings near the south west side of Franklin Creek. The zone comprises a calcareous limestone cobble conglomerate which hosts an area of disseminated and poddy sphalerite with lesser galena and chalcopyrite mineralization. The mineralized zone has been traced in outcrop for approximately 300 metres and is reported to be stratigraphically controlled. Bedding in the area trends approximately 310 degrees and dips 85 degrees to the south west.

In 2005, nineteen grab samples averaged 1.94 per cent zinc with a maximum of 8.84 per cent zinc, 3.98 per cent lead, 1.19 per cent copper, 84.1 grams per tonne silver and 1.91 grams per tonne gold (Caron, L. (2007-03-08): Technical Report on the IXL Property, Franklin Camp).

The area has been historically explored in conjunction with the nearby McKinley (MINFILE 082ENE001) past-producing mine of the Franklin Camp. A short adit or tunnel was driven during the late 1890’s or early 1900’s.
