The Reno-Donnybrook property is on the west limb of the western anticline in quartzites of the Lower Cambrian Reno Formation (correlative with rocks of the Hamill Group). The quartzites are in contact immediately to the west with argillites and calcareous argillites of the Lower Cambrian Laib Formation.

A series of quartz veins, containing visible gold, occur in Reno Formation quartzites, strike 012 degrees and dip vertically to steeply south. Gangue is quartz with occasional quartzite. Metallic sulphides are almost completely absent although visible gold occurs most frequently in areas of quartz stained with limonite.

On the Reno-Donnybrook property, seven parallel quartz veins called the Lake, Clarence, Donnybrook, No. 3 (Middle), No. 1 (or Reno Vein), No. 2, and Crescent have been identified north to south. South of the Crescent, quartz float indicates the possible presence of other veins. Most work has been concentrated on the No. 1, or Reno Vein, but the Donnybrook Vein, 518 metres north, is a well-defined 1 metre wide vein striking 080 degrees and dipping 80 degrees south. It is less oxidized than the Reno and gold values are lower. The Clarence and Lake veins to the north are similar to the Donnybrook Vein.

During 2008 through 2016, Yellowstone Resources Ltd. examined the area as the Sheep Creek property. In late 2016, Margaux Resources Ltd. optioned the property and in 2017 examined the area. A grab sample (SC17-BL01) from a dump located below the Donnybrook adit assayed 0.84 grams per tonne gold (Lane, R.A. (2017-08-17): NI 43-101 Technical Report on the Sheep Creek Project).

Refer to the Reno property (082FSW036) for a summary of the Sheep Creek mining camp.
