The WMC occurrence is located south of Cracker Creek and west of Surprise Lake, about 29 kilometres northeast of the community of Atlin.

Zeunerite occurs in pyritic and clay-altered alaskite of the Late Cretaceous Surprise Lake batholith (Surprise Lake Plutonic Suite), near a small pendant of Mississippian to Triassic Cache Creek Complex volcanics and sediments. The rocks are sheared and contain kaolin, quartz, and sericite.

The WMC showing was located, staked and prospected in August and September 1978 and trenched in August 1979 on behalf of R.H. Seraphim.

In 2002, prospection was done by William B Wallis on the B&B and B&W 1&2 claims, who is the owner of these claims as well.

In 2017, Global Drilling Solutions on behalf of Zinex Mining Corporation conducted extensive geochemical sampling on the Ruby Creek property, as well as drilling and ground geophysics. Rock sample 1532844 returned 0.31 per cent lead, 0.22 per cent zinc and greater than 10 grams per tonne silver (Assessment Report 37171). In 2018, Global carried out further geochemical sampling on the property, and in 2019 they continued work in this region, in the form of prospection, geochemical surveying and a ground geophysical survey.

In 2021, an airborne SkyTEM survey was conducted by Stuhini Exploration on the Ruby Creek property, which revealed a number of regional trends across the property.
