The ET occurrence is located along a northwest-trending ridge between Hornaway and Etschitka creeks, approximately 80 kilometres northwest of the community of Germansen Landing.
The showing area is entirely underlain by medium to coarse-grained, massive, dark green-black diorite of the Early Jurassic Hogem Plutonic Suite. This suite, which consists of numerous intrusive bodies of distinct age, varies in composition between gabbro, diorite, monzonite, syenite and alkali feldspar syenite.
Pyrite, malachite, bornite, and azurite mineralization occurs at numerous locations, but in minor amounts, over a northeast-trending area, two kilometres in length. Alteration consists mainly of epidote and limonite along with weak argillic and biotite alteration. In 1991, the best assay, derived from argillically altered diorite, was 0.15 gram per tonne gold and 1.1 per cent copper (Assessment Report 21426).
In 1990, Cyprus Gold (Canada) Ltd. conducted reconnaissance-style geological mapping, soil and rock sampling, and proton magnetometer surveying on the ET property; a total of 99 soils and 26 rock samples were collected, and 7.7 line-kilometres of ground magnetics completed.
In 2009-10, C.O. Naas examined the provincial Regional Geochemical Survey data and British Columbia MINFILE which led to the staking of the Thane Creek property tenures. A comprehensive compilation of historical exploration work was undertaken and identified four areas that indicated excellent potential for copper-gold mineralization. In 2010, a property visit was carried out and explored three of the target areas identified by the compilation program. Exploration consisted of geochemical sampling with collection of 10 silt samples and 69 rock samples. In 2011, owner/operator C.O. Naas conducted exploration work on the Thane property which comprised prospecting and soil sampling. A total of 290 rock samples, 16 silt samples and 319 soil samples were collected; rock and silt samples were submitted for laboratory analysis and the soil samples were analyzed using a handheld XRF device.
