The LOGAN RIDGE occurrence, located on Logan Ridge, west of Mud Lake, is in the northern region of the Salal property. The ridge is 3.4 kilometres north of Salal Peak and 40.3 kilometres west of Gold Bridge, B.C.

Locally, a contact zone between a fine-grained and a coarse-grained quartz monzonite hosts banded wide quartz veins and stock works, up to 0.4 metre wide, with pyrite and molybdenite mineralization occurring as fine-grained fracture coatings to bands with sericitic margins. The zone is exposed over a width of 500 metres, with the most intense veining occurring over a width of 200 metres.

In 1965, a grab sample assayed 0.246 per cent molybdenum (Assessment Report 709).

In 2007, three grab samples on the Logan Ridge (148404 to 148406) of quartz-sericite-pyrite stockwork and sheeted veins returned molybdenum values of 0.138 to 0.161 per cent (Assessment Report 29575).

In 2008, a grab sample (148756) of fine-grained quartz-pyrite-molybdenum vein rimmed by sericite assayed 3.6 grams per tonne silver and 0.243 per cent molybdenum. In 2012, a previous sample was resampled for rhenium and yielded 82 grams per tonne (Assessment Report 31091).

In 2011, a lone diamond drill hole (MSA-004) intersected a 24 metre long zone of molybdenum mineralization with values up to 0.089 per cent molybdenum over 1.0 metre,; including 0.031 per cent molybdenum over 5.0 metres and 0.011 per cent molybdenum over 94.6 metres (Assessment Report 33341).

During the same year, a 200 metre rock chip sample encountered a 2.5 metre zone of intense silicification hosting fine-grained molybdenite in east-striking, poly-phase quartz-pyrite veins, stockworks and joints near a contact zone, which assayed 0.0353 per cent molybdenum (Assessment Report 33341).

From 1965 to 1966, Southwest Potash Corp. optioned the property and staked additional ground, following which they completed a program of surveying, geological mapping, reconnaissance geochemistry and diamond drilling. In 2007 and 2008, Paget Minerals conducted small exploration programs to confirm past accounts of mineralization on the Salal property. Work included mapping and rock sampling in the Mud Lake and Logan Ridge area in the northern section of the property.

In early 2010, Miocene Metals Ltd. conducted airborne geophysical surveys over the Salal property. In late 2010 and throughout 2012, Miocene Metals Ltd. completed extensive programs of sampling, prospecting, mapping and four diamond drill holes on the Salal property. In 2022, minor soil and silt sampling and drone photogrammetric surveys were conducted in areas of the Salal property for R. Billingsley.
