The Greyhound (Lot 1014) and Ah There (082ESE049) claims are centred just northwest of the confluence of Motherlode and Greyhound creeks and approximately 2.5 kilometres northwest of Greenwood. The adjoining claims are readily accessible from the Motherlode Creek road. The Mother Lode (082ESE034) and Sunset (082ESE035) claims lie 1700 metres to the northwest.

The property is underlain by skarnified units of the Triassic Brooklyn Group and granodiorite which forms the west boundary of the Jurassic-Cretaceous Greenwood pluton. Pulaskite dikes, feeders to the Eocene Marron volcanic rocks, are common.

Mineralization consists of pyrite, chalcopyrite, pyrrhotite, magnetite and specularite, occurring on fractures and interstitially near the contact of the carbonate rocks, skarn and the granodiorite.

Production from the Greyhound open pit in the brief period of mine operations from 1970 to 1971 amounted to 803,326 tonnes of ore, yielding 15.6 kilograms of gold, 349 kilograms of silver and 597 tonnes of copper.

Estimated ore reserves for the Greyhound pit are reportedly about 180,000 tonnes averaging 0.6 per cent copper.

Combined (proven and possible) reserves at the Mother Lode and Greyhound are 407,288 tonnes grading 4.45 grams per tonne silver, 0.51 grams per tonne gold, and 0.65 per cent copper (Royex Sturgex Mining Ltd., Information Circular, 27/04/84).

A grab sample assayed 0.6 per cent copper, 4.0 grams per tonne silver and 0.074 per cent cobalt (EMPR Bulletin 101, Appendix 4B).

The Greyhound claim was Crown granted in 1898 to W.J. Harris. Work began on the Greyhound claim in 1900 with some underground exploration which included a shaft, 60 metres deep, and a crosscut driven from the bottom. Except for a number of brief exploration projects, such as some diamond drilling in 1912, 1916 and 1956, the property remained more or less dormant until open pit mining on the Greyhound claim began in 1969 and continued through 1971. This excavation amounted to about 900,000 tonnes of ore and waste material. Mascot Mines & Petroleum Limited purchased the property in 1973. They conducted magnetometer, geological and geochemical surveys, and drilled 2118 metres in 25 diamond drill holes, 224 metres in 7 rotary holes and 935 metres in 15 percussion holes on the combined Greyhound and Mother Lode properties.

In 1996, YGC Resources completed 814 metres of diamond drilling in 7 holes on the property.

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 2011, diamond drilling yielded intercepts of up to 0.15 gram per tonne gold over 84.0 metres, 2.97 grams per tonne gold over 0.97 metre and 2.54 grams per tonne gold over 1.50 metres in hole 11ML01 and 2.72 grams per tonne gold over 1.50 metres in hole 11ML02 (Dufresne, M. (2013-11-25): Technical Report for the Greenwood Gold Project).
