The G. A. R. (L.822) occurrence is located west of Boundary Creek, approximately 2.5 kilometres north-northwest of Greenwood.

The area is underlain by chert, limestone, siliceous argillite and siliclastic rocks of the Devonian to Permian Knob Hill Group, which have been intruded by granite and granodiorite of the Cretaceous Greenwood stock (Anstey pluton) and Miocene pulaskite porphyry. Undivided sedimentary rocks of the Triassic Brooklyn Formation outcrop to the west.

Locally, a 0.1- to 0.35-metre wide quartz vein hosting galena and sphalerite is reported. The vein has been traced along surface for approximately 60 metres in a west-southwest by east-northeast direction. It is thought the vein could be a continuation of the Sudbury vein of the Gold Bug (MINFILE 082ESE048) occurrence to the southwest.

In 1926, a sample (no. 7) of the vein from the shaft, taken approximately 1.5 metres from the collar, assayed 5.5 grams per tonne gold, 2366.6 grams per tonne silver and 3.1 per cent lead (Property File - B.W.W. McDougall [1926-10-20]: The D.A. Group Of Mineral Claims and the Dynamo Mineral Claim - Deadwood and Skylark Camps - Boundary District).

The area has been explored since the 1890s in conjunction with the nearby Mother Lode (MINFILE 082ESE034) and Providence (082ESE001) past-producing mines. Development work has included a 25.5-metre shaft.

During 2008 through 2012, Grizzly Discoveries Inc. completed programs of rock and soil sampling, geological mapping, ground geophysical surveys and diamond drilling on the area as the Motherlode portion of the Greenwood property.
