The Mad Squirrel (Ridge) occurrence is located at an elevation of approximately 1120 metres on a small southwest-trending ridge, east of Brennan Creek and approximately 2.2 kilometres north-northeast of the northeast end of Johnson Lake.

Regionally, the area is located near the contact between the mid-Cretaceous Baldy Batholith, the Upper Proterozoic to Lower Cambrian Graffunder Lakes unit and a late Devonian orthogneiss unit, all of the Eagle Bay Assemblage. The Eagle Bay Assemblage comprises a series of low-grade metasedimentary and metavolcanic rocks, including micaceous quartzite, grit, phyllite and quartz mica schist, accompanied by minor amounts of chlorite schist, limestone, calcareous phyllite, calc-silicate schist and amphibolite.

Locally, areas of quartz veining host pyrite±galena mineralization have been identified in outcrop and float associated with areas gold-silver anomalies in soil and stream sediments. These zones have been referred to as the Ridge, Spring, Hairpin, Loring Silver, Upper Harvey Road (Silver Road) and Upper Athelstan zones. The Spring, Hairpin, Loring Silver, Upper Harvey Road (Silver Road) and Upper Athelstan zones are located approximately 2.0 kilometres to the north-northeast, 3.3 kilometres to the north, 3.2 kilometres to the northeast, 3.7 kilometres to the east-northeast and 4.2 kilometres to the northeast, respectively, of the Ridge zone.

In 2006, a float sample (T06/01-Rk) of phyllite with a narrow quartz vein and disseminated pyrite from the Loring Silver area assayed 0.350 gram per tonne gold (Assessment Report 28913).

In 2007, a float sample (T07/003-RK-B) of quartz hosting pyrrhotite, minor blebs of chalcopyrite, galena, and trace tetrahedrite from the Loring Silver area assayed 0.278 gram per tonne gold (Assessment Report 28913).

In 2008, two samples (T.08/185-RK and T.08/184-RK-A) from galena-pyrite bearing quartz veins, up to 0.4-metre wide and separated by 80 metres, in the Upper Harvey Road zone assayed 317.2 and 232.8 grams per tonne silver, respectively (Assessment Report 30419). It is not known if these were outcrop or float samples. Also at this time, two other samples (T.08/12-RK and R.08/100-RK) of volcanics hosting quartz veins with pyrite, located on the Hairpin and Upper Athelstan zones, assayed 17.2 and 25.4 grams per tonne silver, respectively (Assessment Report 30419).

In 2012, sampling (N.Rd-RK and LR.12-01-RK) of two areas of quartz veining with pyrite and minor galena, located 200 metres apart on the Ridge zone, yielded values of 113.5 and 118.0 grams per tonne silver, respectively, whereas a float boulder sample (HP.12-02-RK) hosting pyrite and minor galena from the Hairpin zone assayed 38.5 grams per tonne silver and 0.634 per cent lead (Assessment Report 33680).

In 2013, a sample (HP/13/087RK) from a large boulder with pyrite, located on the Hairpin zone, yielded 9.85 grams per tonne gold, whereas a nearby sample (HP/13/084RK) assayed 1.36 grams per tonne gold (Assessment Report 34398). Also at this time, samples from the Loring Silver and northeastern Ridge zones yielded values of up to 0.63 and 0.22 gram per tonne gold, respectively (Assessment Report 34398). It is not known if these other samples were float or outcrop samples.

In 2015, a sample (SZ/072-RK) hosting minor pyrite and galena from the Spring zone assayed 0.098 gram per tonne gold, 10.5 grams per tonne silver, 0.476 per cent lead and 0.061 per cent molybdenum (Assessment Report 35699). It is not known if this sample was from float or outcrop.

Work History

In 1977, Esso completed an airborne electromagnetic survey on the area.

In 1984, a program of soil sampling and a ground electromagnetic survey was completed on the area as the Bren 1-2 claims.

During 1985 through 1987, Berglynn Resources Ltd. completed programs of geological mapping, prospecting, geochemical (rock, silt, and soil) sampling, a 2.8 line-kilometre ground electromagnetic survey and an airborne magnetic-electromagnetic survey on the area immediately east as the Hut and Over claims.

During 2006 through 2017, the area was prospected and sampled by C. Lowry as the Thrust claims of the Mad Squirrel property.
