The adjoining Keno and Orphir claims are centred on a low ridge just east of the Lone Star haulage road, 3.9 kilometres south of Phoenix and 6.8 kilometres southeast of Greenwood.

Upper Paleozoic rocks on the Keno and Ophir claims consist of volcanics and metasediments of the Attwood Group and greenstones of the Knob Hill Group. These are cut by granodiorites of the Jurassic Nelson Intrusions.

By 1933, development on the property consist of an 11-metre deep shaft on a banded quartz vein (Keno vein) varying from 8 centimetres to 0.9 metre in width and striking 023 degrees northeast. The vein has been traced up for 250 metres and contains pyrite, galena, sphalerite, gold, and silver. Chalcopyrite, pyrite, pyrrhotite and magnetite are also disseminated in limestones. About 46 metres south of this shaft, a crosscut was started with the idea of intersecting the shaft vein about 46 metres south and 8 metres lower in elevation. A second steeply dipping quartz vein intersects the first striking diagonally, at about 110 degrees, across to the shaft. This vein is 15 to 50 centimetres wide and 200 metres in length.

Production from 1935 to 1940 was 294 tonnes of ore yielding 1.2 kilograms of gold, 101 kilograms of silver, 2.7 tonnes of lead, and 0.3 tonne of zinc.

Additional geophysical and geochemical work, sampling, trenching and drilling were done intermittently from 1963 to 1986. Sampling in 1979, on the 310-degree striking Ophir vein averages 20 grams per tonne gold and 8.2 grams per tonne silver across 0.64 metre, along a 55-metre length (Christopher, 1986). In 1980, TriBasin Resources completed detailed sampling on the vein returning 121 metres averaging 9.4 grams per tonne gold across 0.4 metres (Property File - Lee, L. (1990-01-06): Property report: Ophir/Keno).

During 2008 through 2012, Grizzly Discoveries Inc. completed programs of soil, stream sediment and rock sampling, geological mapping and ground geophysical surveys on the area as the Overlander area of the Greenwood property. In 2009, a sample (09JHP104) of mineralized quartz vein from an adit assayed 3.4 grams per tonne gold, 887 grams per tonne silver, 0.139 per cent copper, 2.48 per cent lead and 0.535 per cent zinc (Dufresne, M. (2013-11-25): Technical Report for the Greenwood Gold Project).
