The On 1 showing is 2.6 kilometres northeast of the confluence of Allison and MacKenzie creeks, 5.3 kilometres south-southwest of the summit of Missezula Mountain.

Regionally, the area along the Allison Creek valley is underlain mostly by biotite hornblende granite and quartz monzonite of the Upper Triassic to Lower Jurassic Allison Lake pluton. More mafic phases, comprised of granodiorite, diorite and gabbro, are occasionally present within and along the periphery of the intrusion. The north-trending contact with Upper Triassic Nicola Group andesite and basalt lies east of the valley and comes to within a kilometre east of Allison Lake. The pluton is traversed along the east side of the valley by the north-striking Allison fault. To the south and west undivided volcanic rocks of the Lower Cretaceous Spences Bridge Group are exposed.

Pyrite and chalcopyrite occur in a marginal phase of hornblende diorite, gabbro and quartz diorite of the Upper Triassic to Lower Jurassic Allison Lake pluton. The showing lies just west of the contact with crystal and lithic tuff of the Upper Triassic Nicola Group.

Work History

Zone Explorations Ltd. completed a soil sampling survey over the occurrence area in 1970 as the On claims. In 1973, Aalenian Resources examined the area as the Liard Lake property. Later that year, a program of soil sampling and geological mapping was completed on the area as the Fan claims.

In 1981 and 1982, Cominco Ltd. completed programs of geological mapping, geochemical (rock and soil) sampling and ground geophysical surveys on the area as the Axe property.

In 1996, Glen Rodgers completed a 4.2 line-kilometre ground magnetic and electromagnetic survey on the area as the Broad claim.

During 2010 through 2013, Paul Hoogendoorn and Peter Palikot completed programs of prospecting and geochemical (rock and soil) sampling on the area as the Dry Lake property.

During 2012 through 2015, Colorado Resources Ltd. completed programs of geological mapping, geochemical (rock and soil) sampling and a 6.0 line-kilometre induced polarization survey on the area as the Hit-Aspen Grove property.

In 2018, Evrim Exploration Canada Corp. completed a program of rock sampling, geological mapping, 41 rotary drillholes, totalling 695.3 metres, and 4 diamond drillholes, totalling 2113.6 metres, on the Axe property.
