The Pingree showing is situated near the headwaters of Eagle Creek, southwest of the Eureka mine (MINFILE 082FSW084). A small amount of ore was reportedly removed and shipped from this showing but no record of this exists.

The area, just west of the Silver King shear zone, is underlain by schistose volcanics composed of augite basalt flows, flow breccias and subvolcanic intrusions of the Lower Jurassic Elise Formation, Rossland Group.

The Pingree showing consists of a 0.3 to 1.2-metre-wide quartz vein hosted in schistose material and containing black iron oxides. Subsequent work failed to trace the continuation of the vein or to find further mineralization.

In 1910, the property was owned by Pingree Gold Mines Limited. The property was developed in two portions: the Mayflower tunnel was driven 18.3 metres and intersected ore, and the Pingree tunnel was driven 42.7 metres before encountering an ore shoot, on which a little winze was sunk. One of the adits intersected a sulphide zone in a small quartz vein with gold and copper values. The following year, the tunnel was advanced an additional 30.5 metres. Development work on the Pingree tunnel continued into 1914. By 1915, no orebodies of importance had been discovered despite the completion of considerable development work. Some ore had been shipped from an ore-bearing vein developed by two short drift tunnels, but continuations of the vein could not be located.

In the 1980s, limited exploration was conducted on the Ron Gold claim group to the northwest of the Pingree workings. In 1985, property owners Eric and Jack Denny leased the Ron Gold claim group to Ryan Exploration Company Limited. Exploration that year consisted of geochemical rock and soil sampling. The following year, Ryan Exploration conducted a very low-frequency geophysical survey over the claim group.

Between 1982 and 1986, McMahon Resources Limited conducted geochemical surveys over the 49 Creek claim group to the northeast in an attempt to locate the source of high-grade gold samples collected from the lower drainage of Fortynine Creek in 1970.

By 1989, Pacific Sentinel Gold Corporation had acquired the Pingree claims as part of their Great Western Star property. In the summer of 1989, Lloyd Geophysics Limited carried out geophysical surveys over the Ron and Toughnut grids to the north and east, respectively. In 1990, Pacific Sentinel Gold conducted a follow-up program of soil and rock sampling, trenching, geological mapping and geophysical surveying. Later that year, 26 NQ and NQ2 diamond drill holes totalling 5880 metres were completed. Drilling focused on the area to the north of the Pingree occurrence around the Star, Alma N. (MINFILE 082FSW083), Eureka (MINFILE 082FSW084) and Toughnut (MINFILE 082FSW294) occurrences.

In 2004, on behalf of owner Jack Denny, Klondike Gold Corporation conducted a geochemical sampling program over the Ron property to the northwest, later optioning it in 2008. An exploration program of limited geological mapping and prospecting and soil geochemical surveying was carried out on the eastern portion of the claim group. The Ron property was then acquired by Anglo Swiss Resources and amalgamated with the Kenville (MINFILE 082FSW086) property.

In 2009, on behalf of Anglo Swiss Resources, Equity Exploration Consultants Limited undertook an exploration program consisting of 680 line kilometres of airborne electromagnetic geophysical surveying, surface diamond drilling, and underground rehabilitation and drilling. Ten diamond drill holes were completed on the south side of Eagle Creek, approximately 700 metres south of the Kenville mine.

By 2010, the Kenville property had been expanded to include separate claim groups to the north and south. In 2010, on behalf of Anglo Swiss Resources, St. Pierre Geoconsulting Incorporated conducted airborne magnetic and electromagnetic geophysical surveys over the entire Nelson Mining Camp area. Soil sampling was conducted over the central Kenville claim block, though the majority of the sampling was conducted in the area of the Silver Lynx occurrence (MINFILE 082FSW378) to the south.
