The Buckingham Fraction occurrence is near the northwest headwaters of Greyhound Creek, approximately 2 kilometres northwest of Greenwood.

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

Locally, on the Buckingham Fraction a gossanous zone in a granodiorite hosts a 0.75-metre wide quartz vein with arsenopyrite. The vein strikes north 22 degrees east and dips 48 degrees northwest. The zone has been exposed along a former railroad grade and in a nearby open cut for approximately 60 metres along strike.

On the Great Hopes (L.602) Crown grant, located approximately 300 metres to the north, a limonitic weathered, cherty argillite outcrop hosts gold and silver values.

On the Butte City (L.1230) Crown grant, located approximately 250 metres to the west, a former shaft and pit exposed a mineralized quart-rich rock.

Work History

The area has been explored since the 1890s in conjunction with the nearby Mother Lode (MINFILE 082ESE034) past-producing mine. An unknown amount of sorted ore is reported to have been shipped from an open cut located along the railway grade from Greenwood to the Mother Lode mine.

In 1926, a sample (no.9) across 0.75 metre of the quartz vein on the Buckingham Fraction yielded 4.1 grams per tonne gold with 287.3 grams per tonne silver, whereas a sample (no.8) of dump material (rejects of sorted ore) assayed 4.8 grams per tonne gold, 475.4 grams per tonne silver, 2.8 per cent lead and 5.1 per cent zinc (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).

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. In 2010, a sample (10JHP126) from the Great Hopes Crown grant to the north assayed 51.00 grams per tonne gold and 5.2 grams per tonne silver, while a sample (10WBP259) taken from a former pit located near the Butte City shaft to the west assayed 30.9 grams per tonne gold, 60 grams per tonne silver, 0.259 per cent copper, 0.971 per cent lead and 3.41 per cent zinc (Dufresne, M. (2013-11-25): Technical Report for the Greenwood Gold Project).
