The Gold Hill occurrence is located on the south side the junction of the west and south arms of McGillivray Creek, at an elevation of approximately 1550 metres.

In the region, the Cadwallader and Ferguson faults transect sedimentary and volcanic rocks of the Mississippian to Jurassic Bridge River Complex and the Upper Triassic Cadwallader Group. Linear, altered serpentinite zones called the President Ultramafics, correlative with the Permian and older Shulaps Ultramafic Complex, mark faults that have controlled the emplacement of diorite of the Permian Bralorne Igneous Complex. The above sequence lies between bodies of the Jurassic to Tertiary Coast Plutonic Complex and outlying bodies of Cretaceous to Tertiary Bendor pluton granodiorite.

Locally, a mineralized quartz vein is hosted by argillites and grey argillaceous phyllite of the Mississippian to Jurassic Bridge River Complex (Group). The 90-centimetre to 9-metre wide vein is conformable to bedding, striking southeast and dipping steeply east. It has been traced for 180 metres and eventually splits into several veins. The argillite is silicified for 2.5 metres on either side of the vein. The vein is well defined and cut by jointing running parallel to its length. Pyrite is contained in the quartz and in the surrounding phyllite. A sample from the vein assayed 4.11 grams gold per tonne (Minister of Mines Annual Report 1933, page 261). In 1989, sampling of galena-rich sections of the vein assayed greater than 200 grams per tonne silver (Assessment Report 19604).

A second group of workings is reported on the ridge west of McGillivray Creek forks, where several pits and a 22-metre long adit expose a narrow zone of quartz veining and stockworks in a aplitic intrusive. In 1985, a sample of select vein material assayed 10.2 grams per tonne silver (Assessment Report 14382).

Another quartz vein, known as the Switchback vein, is reported approximately 600 metres to the north east of the main occurrence. The 1 to 2-metre wide Switchback vein trends 158 degrees and dips 80 to 90 degrees and is hosted by a tongue of granite. The vein contains minor galena and sphalerite.

As of 1935, an adit had been driven in for 33.5 metres with two crosscuts, totalling 36 metres, running off, one 6 metres to the east and the other 36.5 metres to the west. In 1983, X-Cal Resources completed a program of rock and silt sampling and geological mapping on the area as the Mac and X-Cal claims. In 1985, Hudson Bay Exploration and Development completed a program of geochemical sampling, geological mapping and a ground electromagnetic survey. In 1989 and 1990, Teck completed programs of rock, silt and soil sampling, geological mapping and a ground electromagnetic survey on the area. In 1991, Cogema completed a program of geochemical sampling and geological mapping on the area. In 2007 and 2008, the area was prospected as the Sarah D claim.
