The Ro showing area is underlain by marine sedimentary and volcanic rocks of the Upper Triassic Stuhini Group. A quartz vein 0.5 metre wide with chalcopyrite occurs in quartz-iron carbonate altered tuffs and argillaceous sediments. A grab sample assayed 0.26 per cent copper, 0.1 gram per tonne gold and 0.6 gram per tonne silver (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. The Ro showing was discovered by the survey team at this time. No work is reported on the showing since discovery.

In 2019, Brixton Metals Corporation expanded their Thorn property through staking and acquisition of claims including those covering the Ro showing. 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.
