The BLACK showing is located 4.5 kilometres south of Arlington Lakes, and approximately 9.5 kilometres north-northeast of Carmi.

The showing consists of a quartz vein hosted by an unnamed Middle Jurassic gneissic quartz diorite intrusion. This intrusion was previously mapped as part of the Middle Jurassic Nelson Intrusions (Geological Survey of Canada, Map 1736A). The quartz diorite lies near the west contact of a north-south band of Carboniferous-Permian Anarchist chlorite-biotite schist.

The general area has numerous old workings, pits, and adits which date from the early 1900s. Exploration work in the general area includes a 1971 magnetometer survey for Hudson's Bay Oil and Gas Ltd. and prospecting and geological mapping in 1973 for K.F. Brunning. The showing was first sampled by James McLeod, who carried out a prospecting program for Edward Carson & Associates in 1987.

A composite chip sample of the quartz vein, which contained chalcopyrite and molybdenite, assayed 1.72 per cent copper, 52.69 grams per tonne silver, 1.19 per cent molybdenum and 0.68 grams per tonne gold (Assessment Report 17030). Additional information about the vein is lacking.

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.

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. Sampling on the Black occurrence area yielded values of up to 1.05 per cent copper, 0.356 per cent molybdenum, 37.7 grams per tonne silver and 0.13 gram per tonne gold (Sample 1750352; Chapman, J.
