The BRU 22 showing is located 2.5 kilometres south of Arlington Lakes, and approximately 12 kilometres north-northeast of Carmi.
The showing consists of 3 adits driven eastward on a quartz vein in a northwest-southeast trending shear zone. The shear zone cuts through quartz diorite of an unnamed Middle Jurassic intrusion. This intrusion was previously mapped as Nelson Intrusions (Geological Survey of Canada Map 1736A). Hematite is noted to occur in the shear zone, and it is reported that disseminated chalcopyrite and pyrite are commonly associated with specular hematite in and around shear zones in diorite on this property.
The general area has numerous old workings, pits, and adits which date from the early 1900s. More recent work includes a 1971 magnetometer survey for Hudson's Bay Oil and Gas Ltd. and prospecting and geological mapping in 1973 for K.F. Brunning. Additional prospecting was carried out in 1970 by James Mcleod for Edward Carson & Associates.
The 1971 magnetometer survey identified a magnetic anomaly along the geological contact between a gneissic diorite and a mafic diorite (both contact phases of the Nelson, possibly containing assimilated Anarchist?). It was noted that copper mineralization is coincident with this magnetic anomaly. Assays are not reported for the BRU 22 showing.
In 1996, Madman Mining Co. Ltd. completed a prospecting, soil sampling, and a VLF-EM geophysical survey on the property containing the occurrence.
In 2015, Explorex Resources Inc completed magnetic and VLF-EM geophysical surveys, a prospecting and sampling program on the property containing the occurrence. Highlighted results included a grab sample grading 10.89 grams per tonne gold at the Bru 22 occurrence (Kemp, R. (2017-07-13): National Instrument 43-101 Technical Report on the Arlington Property).
In 2017, Coast Mountain Geological Ltd. completed an exploration program including soil sampling, rock sampling, and 26.4 line-kilometres of ground magnetic and VLF-EM surveys.
In 2018, Clarmin Exploration Inc. completed a prospecting and soil sampling program on the Arlington property (Assessment Report 36956). The property was returned to Explorex Resources Inc. in late 2018.
