Capsule Geology

The Jon showing area is underlain by marine sedimentary and volcanic rocks of the Upper Triassic Stuhini Group. The showing consists of banded quartz-carbonate veins with pyrite, tetrahedrite and arsenopyrite that occur in an extensive zone of strongly iron-carbonate altered mafic tuffs. A grab sample assayed 1.17 grams per tonne gold and 0.84 per cent arsenic (Open File 1993-1, Lithogeochemical Analyses table, sheet 2 of 3).

In 1992, a BC Geological Survey geological mapping project in the Tatsamenie and Bearskin lakes area resulted in an updated regional geological framework and the discovery of several new showings including DB (104K 121), Ro (104K 123) and Jon (104K 124).

In 2019, Brixton Metals Corporation expanded their Thorn property through staking and acquisition of claims including those covering all the Highliner (104K 099), Oro 4 (104K 100), DB (104K 121), Ro (104K 123) and Jon (104K 124) showings. In 2020, Brixton Metals Corporation completed a program of geochemical (rock and soil) sampling, a 12.5 line-kilometre ground induced polarization survey, a 715 line-kilometre airborne magnetic and electromagnetic survey and 19 diamond drill holes, totalling 5292 metres, on the area of as part of the Thorn property. Drilling was performed on the Outlaw (MINFILE 104K 176) occurrence area. No work is reported on the Jon showing since discovery.

Refer to nearby Highliner (104K 099) and DB (104K 124) showings for related information, and Golden Bear (104K 079) for significant information on area geology and work history.
