The Arsenio (Arsenic Vein) showing is located approximately 750 metres southwest of Maggie Lake.

The area is underlain by an assemblage of diorites to quartz diorites belonging to the Paleozoic and/or Mesozoic West Coast Complex.

The showing consists of quartz lenses, heavily mineralized with arsenopyrite, that occur at the contact of a dacite dike. The dike, from 30 to 40 centimetres in width, strikes 032 degrees and dips 68 degrees west through an unspecified host rock (assumed to be diorite). A lense or vein has been exposed in a creek bed along a strike length of 10 metres. The quartz pods and lenses range from 1 to 5 centimetres in length. Alteration consists of chlorite, lesser epidote, and limonite.

During 1986 through 1988, Geo. P.C. Services Inc. completed programs of prospecting, geological mapping and geochemical sampling on the area as the Tert 5 claim, Dom Group. Five rock samples yielded up to 0.77 grams per tonne gold and 7.0 grams per tonne silver with arsenic values from 2.5 to 3.5 per cent (Assessment Report 17400).

During 1995 through 2009, Consolidated Logan Mines Limited and later Logan Resources Limited, completed programs of prospecting, geological mapping, geochemical sampling and an induced polarization survey on the Lucky and Redford properties.
