The Cathedral occurrence is located at an elevation of approximately 1010 metres on a southwest-facing slope, northeast of Cambridge Creek and 1.5 kilometres northwest of Lookout Mountain.

Regionally, the area is underlain by augite-phyric lapilli tuff, pyroclastics and flows of the Lower Jurassic Elise Formation (Rossland Group), which have been intruded by quartz monzonitic rocks of the Early Jurassic Rossland Plutonic Suite, granodioritic rocks of the Middle Jurassic Nelson Batholith, granitic rocks of the Eocene Sheppard Intrusions and syenitic to monzonitic rocks of the Eocene Coryell Plutonic Suite.

Locally, silicified metavolcanics (Elise Formation) immediately adjacent to the contact with a monzonite (Rossland Plutonic Suite) host a 0.2- to 0.5-metre wide quartz vein with minor chalcopyrite and pyrite. Gouge minerals include chlorite and calcite. The vein trends approximately 285 degrees with a dip of 45 to 50 degrees to the north.

Another zone of mineralization, located approximately 400 metres up slope to the southeast and exposed by a former shaft, comprises a zone of minor fracturing and quartz veining.

In 2006, three samples (CH-0070, -0071 and CP-0109) from the Cathedral vein and workings yielded from 24.58 to 45.59 grams per tonne gold, 4.8 to 23.4 grams per tonne silver and 0.044 to 0.177 per cent copper, whereas a sample (RP-48) from the shaft of the southeastern zone yielded 0.440 gram per tonne gold (Assessment Report 28996).

The area has been explored since the late 1800s with numerous former pits, trenches and a 10-metre long adit dating to this period.

In 1986, a program of prospecting, geological mapping and rock sampling was completed on the area as the Beaver claim. In 1987, a program of prospecting and a ground magnetic survey was completed on the adjacent Oriental (L.1701) reverted Crown grant. In 1987 and 1988, Tobex Resources completed programs of geochemical sampling, geological mapping, a 113.0 line-kilometre airborne geophysical survey and 14 diamond drill holes, totalling 936.0 metres, on the surrounding area as the Gold Dust claims. In 1989, Inland Au-Ag Resources Ltd. completed a program of geological mapping and a 4.4 line-kilometre ground magnetic survey on the area as the Beaver claim.

In 1997, Loumic Resources Ltd. completed a program of geological mapping and six diamond drill holes, totalling 1013.1 metres, on the area as the Red Point property. In 1999, Inmet Mining Corp. completed a 16.9 line-kilometre ground electromagnetic survey on the area.

In 2006, Klondike Gold Corp. completed a program of soil sampling, geological mapping, 20.3 line-kilometres of ground geophysical surveys, a 317.8 line-kilometre airborne geophysical survey and five diamond drill holes, totalling 809.3 metres, on the area as the Red Point property.
