The old Tidal (Tital?) Wave showing is located on the summit of the ridge above Westholme, apparently on Land Lot 93. This lot is located to the immediate east of the Ironclad workings (MINFILE 092B 049).

The area is underlain by rocks of the Upper Devonian McLaughlin Ridge Formation (Sicker Group). The strata is intruded by gabbroic rock (informally known as the Mount Hall Gabbro) that is coeval with the Upper Triassic Karmutsen Formation (Vancouver Group)

Locally, A pit up to 6 metres in depth exposes a 1 metre wide quartz vein trending west through gabbro. The vein is virtually barren except for an occasional speck of malachite (Notes by Wright, 1969).

In 1969, Canpac Minerals explored the area as the Sirius claims. A program of geological mapping and a ground magnetic survey was completed. In 1978, the area was staked as the Croft 2 claim and a program of geological mapping and soil sampling was completed. In 1983, the area was staked as the West claims by R.J. Bilquist and a program of prospecting was completed. In 1984 and 1985, Falconbridge optioned the property and completed programs of geochemical sampling and an airborne geophysical survey. In 1987, Falconbridge completed a drilling program of 10 holes, totalling 3170.7 metres, in the vicinity of Breen Lake on the West 1 claim. In 2010, Westridge Resources completed a program of geological mapping and geochemical sampling on the Breen Lake area.
