The MAG showing is located on the Fraser Plateau, approximately 1 kilometre east of the Cariboo Highway 97, 2 kilometres east of Cottonwood River and 19 kilometres northeast of Quesnel.
The area is underlain by Late Triassic volcaniclastics of the Takla Group Witch Lake Formation. Granite and alkali feldspar granite intrusive rocks of the Cretaceous Naver Pluton, and associated satellite bodies, intrude the Nicola rocks.
Mineralized rhyolite dikes intruded argillite on the Mag claims were sampled by Thios Resources in 1986. Chip samples taken of silicified breccia consisting of fragments of argillite and rhyolite dike material which are partly replaced by pyrite and cemented with fine silica mixed with clay, calcite and sericite (?), analyzed 1.6 grams per tonne gold (Sample M3KR13). The highest assay, obtained from the least weathered part of the dike (above the water level), contained 2.2 grams per tonne gold 37.7 grams per tonne silver and 0.22 per cent lead and 4.1 per cent arsenic (Sample M3R1)(Assessment Report 15848). This sample exhibits the fragmental texture characteristic of hydrothermal breccias.
In 1986, Thios Resources Inc conducted exploration on their Mag claims collecting 4 heavy mineral samples, 20 rock samples 289 soil samples and completed 88.9 kilometres of VLF-EM and ground magnetic surveying. Richfield Ventures Corp held the Mag ground from 2005 to date (2009) and have explored various parts of their large tenure holdings including Mouse Mountain (Minfile 093G 003) and G-South (Minfile 093G 007).
From 2016 through 2021, Barkerville Gold Mines Ltd. conducted exploration works on their Bellos property centred over the Mag occurrence. Initially, 250 line-kilometre helicopter-borne electromagnetic (VTEM) and magnetic surveys outlined a northwest-southeast anomalous zone associated with a magnetic low. Follow-up stream sediment surveys and prospecting resulted in encouraging values with a peak value of 0.354 gram per tonne gold. In 2021, a 501 sample soil survey resulted in 19 anomalous gold samples proximal to the previously defined northwest-southeast magnetic anomaly.
