The Rin occurrence is located on an east-west–trending ridge, east of the Tucho River and approximately 19.5 kilometres northeast of its junction with the Pitman River.

Regionally, undivided volcanic rocks of the Upper Triassic Shonektaw Formation (Takla Group) and the Lower to Middle Jurassic Bowser Lake Group, both of the Quesnel terrane, have been intruded by a large Lower Jurassic pluton (Pitman Batholith) consisting of biotite-hornblende quartz monzonite, granodiorite and quartz diorite.

At the Rin occurrence, plutonic rocks are reported to host clusters of coarse molybdenite and chalcopyrite in two parallel quartz veins approximately 1.5 metres apart. The veins strike north, dip 50 to 60 degrees to the west and outcrop along a steep north-northeast–facing slope; the surface trace of the veins trends to the southeast. The upper zone attains a maximum thickness of 0.6 metre but pinches to zero thickness at a couple of points along the 23-metre length. The lower vein maintains a width of 0.37 to 0.76 metre for approximately 15 metres and then splits into several narrow (less than 7.6-centimetre) veins. These veins pinch out after approximately 21 metres.

In 1971, the veins were sampled along the best mineralized sections over an average width of 0.52 metre and a combined length of 8.8 metres. The weighted average was 1.42 per cent copper and 0.20 per cent molybdenite (MoS2; Assessment Report 3215).

In 2012, a float sample (1725242) of epidote (propylitic)-altered granodiorite hosting bornite and chalcopyrite, taken from a northeast-facing slope and approximately 6 kilometres to the northeast of the plotted location of the Rin occurrence, assayed 0.596 per cent copper (Assessment Report 34267).

Work History

In 1971, Conwest Exploration Ltd. prospected and sampled the Rin claims.

In 2011 and 2012, Teck Resources Ltd. completed programs of prospecting, geochemical (rock and silt) sampling and a 6411.9 line-kilometre airborne electromagnetic (ZTEM) survey on the area as the Pitman property.
