The showing is located on the eastern flank of Mount Mohan, approximately 8.5 kilometres northeast of the community of Yahk.
The area is underlain by the Aldridge Formation, the lowermost Purcell Supergroup strata. The lower Aldridge Formation exposed is primarily of the Ramparts facies, consisting of generally thick bedded, grey weathering quartz and quartzitic wackes. These grade upward into medium to thick bedded grey weathering turbidites of the middle Aldridge Formation. Both the lower and middle Aldridge Formations are intruded by Middle Proterozoic dioritic to gabbroic sills of the syn-depositional Moyie intrusions.
Two zones of stratiform zinc-lead mineralization have been discovered in the Middle Aldridge in the Cold Creek area. The Can Am showing south of Hawkins Creek containing a 300-meter-thick zone of disseminated sphalerite and galena. And drill hole YA-6 on the east slopes of Mount Mahon contains a semi-massive sulphide interval with pyrrhotite, sphalerite, and galena. Extension of drill hole MM91-1 just east of YA-6 was an attempt to target the prospective Sullivan horizon at the Lower Aldridge-Middle Aldridge contact.
In the Yahk area, St. Eugene Mining Corporation Ltd. first mapped tourmalinite occurrences on Mt. Mahon. In 1980-1981, a thirteen-hole drill program was conducted. Drill hole YA-6 intersected a massive sulphide zone at a shallow depth. In 1984, Chevron Canada Resources Ltd. optioned the property and drilled two holes to test the LMC on Mt. Mahon. Minnova Inc. optioned the property in 1991. Six holes were drilled in search of extensions to the mineralization intersected in hole YA-6.
Abitibi Mining Corp. carried out prospecting, geochemical sampling and mapping on the Yahk property in 1997 and 1998. In 1997/1998, Abitibi Mining Corp collected more than 3486 soil samples on the Yahk Claim Group (Hot claims) (Mt. Mahon area) for geochemical analysis (Assessment Report 25271 and 25568). Some 42 rock samples and 17 petrographic samples were also collected, and a 475 kilometres gravity survey was completed. Abitibi drilled three closely spaced holes in 1998 on the east flank of Mt. Mahon. In 1999, drill hole #YK99-1 was collared on the east flank of Mt. Mahon, at a site of previous drilling by Abitibi Mining Corporation.
In 2001, Klondike Gold Corp. optioned the property and drilled several short holes on the slopes east of Cold Creek.
In 1999, drilling (YK99-1) intersected gabbro sills with disseminated patches of pyrrhotite and/or pentlandite and lesser chalcopyrite. Sample 7667 returned values of 12.84 grams per tonne gold over 0.80 metre (Assessment Report 26121).
In 2020, a program of rock and soil sampling was conducted by Kootenay Resources Inc on their Moyie Anticline property utilizing both laboratory and portable XRF analytical techniques (Assessment Report 39483). During the 2020 field program more than 1420 XRF readings were taken and compiled. Several areas with anomalous lead, zinc, copper as well as gold were found during the program. The Moyie Anticline property covered parts of the 082GSW and 082FSE map areas.
In 2021, Kootenay Resources Inc. contracted Salt Spring Imaging, Ltd. to record and analyse magnetotelluric data on the Moyie anticline (Assessment Report 40348).
