The Bud 7 (Green) showing area is located approximately 7 kilometres north of McLeese Lake and is part of the property owned by Gibraltar Mines Limited, a subsidiary of Taseko Mines Limited. Access is via the Ross Lake logging road which connects to the mine access road about 6.4 kilometres north of the Highway 97 turnoff. The property can also be accessed from the mine plant site via a haul road.

A Jurassic to Triassic quartz diorite stock probably related to the Granite Mountain Pluton intrudes Mississippian to Triassic Cache Creek Group andesitic to rhyolitic flows, tuffs, breccias, and limestones. The meta-andesites host disseminated pyrite, specularite, and minor magnetite. The Cache Creek rocks have undergone sericitic and propylitic alteration hosting abundant chlorite, epidote, sericite, quartz, carbonate, and pyrite.

In the 1986 drilling, a 21 metre thickness of limestone was intersected between the faulted contact of the Cache Creek and quartz diorite intrusion. In the vicinity of the fault there is extensive skarning and brecciation. The fault strikes northerly across the Cuisson Valley and dips 40 degrees west.

The quartz diorite hosts disseminated chalcopyrite, bornite, and minor molybdenite as well as chalcopyrite in quartz-carbonate veinlets. In 1986, drilling intersected mineralization grading 0.28 per cent copper and 0.01 per cent molybdenite (Assessment Report 15797). The Granite Mountain pluton has undergone pervasive saussurite-chlorite alteration. Four economic zones have been recognized and are in various stages of development.

The original claims of the Green claim group were staked between 1966 and 1976 to cover a portion of the Granite Lake Pit and ground south and east of the pit. Currently, the claim group consists of both mining leases and mineral claims. After initial exploration work was completed and mining had commenced, additional drilling programs were carried out in 1987 and 1988. During September 1999, mineral claims Gib 15 Fr, Sap 2 Fr and Sap 3 Fr were dropped. In 1999, Gibraltar Mines Ltd. conducted a program of geochemical surveys and soil drilling on the Green Group to determine if additional mineralized structures existed between the Gibraltar and Sawmill mineralized trends. No significant anomalous values were found (Assessment Report 26064). In 2000, an induced polarization geophysical survey was conducted on the entire property.
