The Switchback occurrence is located southwest of Le Mare Lake, at 237 metres elevation.
The area is entirely underlain by Lower Jurassic Bonanza Group intermediate to felsic volcanic flows and pyroclastics. The rocks have undergone low-grade metamorphism as exhibited by the presence of zeolite and laumontite.
Locally, rhyodacites and andesites host chalcopyrite and pyrite mineralization.
Work History
In 1979, the Le Mare claims were first staked and prospected the following year by Brinco. In 1998, Phelps Dodge completed a program of prospecting on the Lem property. In 2007, Homegold Resources completed a program of prospecting and geochemical sampling on the Farwest claims. Between 2008 and 2012, New Destiny Mining completed various programs of geological mapping, prospecting and geochemical sampling on the Le Mare claims. In 2014, a small program of geological mapping, prospecting and examination of workings was conducted by J.T. Shearer, the property owner. In 2016, J.T. Shearer completed a further program of geological mapping on the Le Mare property. The property was examined in 2017 by W.B. Lennan on the behalf of Le Mare Gold Corp. Also at this time, J.T. Shearer completed a minor program of rock sampling and a 6.1 line-kilometre ground magnetic survey on the Le Mare property. In 2020, J.T. Shearer completed a minor program of rock sampling and a 5.8 line-kilometre induced polarization survey on the Le Mare property.
