The Sinclair occurrence is in the southern headwaters of Sinclair Creek, at an elevation of approximately 1850 metres.

The area is underlain by quartzite, wacke, argillite and siltstone of the mid-Proterozoic (middle) Aldridge Formation (Purcell Supergroup), intruded by meta-gabbro or meta-diorite of the Proterozoic Moyie Intrusions.

Locally, thin bedded lead-zinc mineralization occurs in a 60-metre thick mudstone unit that has been traced on surface for 600 metres. Diamond drilling intersected stratiform sphalerite mineralization 90 metres down-dip from the surface showing. Mineralization consisted of 40 thin, bedding-parallel bands of disseminated sphalerite and pyrrhotite ranging in thickness from 1 to 10 centimetres. The sulphide-rich bands are scattered throughout a 150-metre section of thin-bedded argillite and silty argillite of the mid-Proterozoic (Helikian) Aldridge Formation (Purcell Supergroup).

In 2014, drill core samples from previous drilling, assayed up to 0.114 per cent zinc (Sample 1621560; Assessment Report 34880).

In 1987, Esso Resources completed a program of rock and silt sampling, geological mapping and a 3.0 line-kilometre electromagnetic survey on the area immediately east as the Mac 1-10 claims. In 1993 and 1994, Cominco completed 36.6 line-kilometres of electromagnetic surveying on the area as the Roar claims.

In 1999, Chapleau Resources Ltd. completed two short diamond drill holes (P99-4, 5), totalling 371.6 metres, on the occurrence. In 2001, a single, 291.7-metre, diamond drill hole (PAKK00-15) was completed. In 2014, D. Anderson completed a program of logging and sampling of two cores drilled in 1999 and 2000. In 2015, the area was prospected and sampled by T. Kennedy.
