The Gold Leaf (Gold Run) occurrence is located on the ridge north of the west end of Gold Run Lake, at an elevation of approximately 2000 metres.

The area is underlain by grey to purple-coloured quartzites and siltstones with minor interbedded argillite that are part of the mid-Proterozoic Creston Formation (Purcell Supergroup). These metasedimentary rocks (biotite facies of regional greenschist metamorphism) have a strike from 020 to 025 degrees and dip steeply west.

Locally, a sericitic and brecciated quartzite and argillite host north east-trending quartz veins with disseminated pyrite and limonite.

In 1999, four rock samples (Zing-08, 18, 21 and 22) assayed from 1.00 to 4.12 grams per tonne gold (Assessment Report 26216).

In 2013, a rock sample (ZG13-87) assayed 1.7 grams per tonne gold (Assessment Report 34730).

During 1915 through 1921, the area was extensively prospected with several trenches. In 1985, Trans-Artic Explorations completed a program of prospecting and rock sampling on the area as the Hawk 1 claim. Also, at this time the Fort Steele Grubstaking Syndicate conducted a program of soil and rock sampling on the area as the CND claims. The following year, Unique Resources completed a program of soil sampling and ground magnetic and electromagnetic surveying. In 1987, Chapleau Resources completed a program of soil, silt and rock sampling, trenching and geological mapping on the area as the Racki claims, Morgan property. Also, in 1987 Partners Oil & Minerals completed a program of soil sampling and a 47.5 line-kilometre combined electromagnetic and magnetic survey on the area. During 1997 through 1999, programs of soil and rock sampling, geological mapping and ground electromagnetic surveying were completed on the area as the Zinger claims. During 2000 through 2002, National Gold Corporation completed programs of geological mapping and silt, soil and rock sampling on the area as the HS and Zinger claims. In 2003, Chapleau Resources conducted an extensive exploration program of surface prospecting, rock and soil sampling and geological mapping on the area as the Zinger property. In 2009, Ruby Red Resources prospected and sampled the area. During 2010 through 2013, SG Spirit Gold and PJX Resources completed programs of rock and soil sampling, geological mapping and airborne and ground geophysical surveying on the area.
