The Harvey Cove Geyserite occurrence is located south of Culleet Lake, approximately 600 metres west of the western arm of Le Mare Lake.

The area is underlain entirely by Lower Jurassic Bonanza Group intermediate to felsic volcanic flows and pyroclastics that have undergone regional low-grade zeolite and laumontite metamorphism. Dark green andesite flows, dacite lapilli tuffs and rhyodacite crystal tuff are intruded by sporadic andesite dikes and bisected by steeply dipping faults.

Locally, geyserite and chalky geyserite are exposed on the Restless Mainline Road.

Work History

In 2008, Electra Gold Limited completed a program of prospecting and sampling. Also, during 2008 through 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.
