The Rabbitt mine is located 0.5 kilometre southwest of Lawless Creek, 2.5 kilometres east-northeast of the summit of Grasshopper Mountain and 8 kilometres west-northwest of the town of Tulameen.

The area on the east flank of Grasshopper Mountain is underlain by various metasediments and metavolcanics of the Upper Triassic Nicola Group. These rocks strike north to northwest and dip steeply west. This deposit consists of two intersecting veins hosted in chloritized and sheared greenstone. The main or "adit" vein strikes 000 to 010 degrees for 100 metres and dips vertically to steeply west for at least 35 metres. The vein is 0.30 to 3 metres wide and is accompanied by a quartz vein stockwork along its hangingwall. It is reported to be largely mined out (Assessment Report 15723). The vein is comprised of porcelaneous quartz and ankerite mineralized with chalcopyrite and pyrite, as blebs and scattered grains. A chip sample across 1.15 metres assayed 17.2 grams per tonne gold, 7.2 grams per tonne silver and 0.19 per cent copper (Assessment Report 12434, page 9).

The second vein strikes 040 to 045 degrees and intersects the main vein at the south end of the mine workings, where it is up to 1 metre wide. Sulphide mineralization consists of chalcopyrite and pyrite, with traces of galena and sphalerite. A bulk sample of 298 kilograms assayed 2.9 grams per tonne gold (Assessment Report 15723, page 28). This vein is part of a system of veins and breccias that has been traced southwestward from the main workings for 175 metres in chloritized, limonitic, variably silicified and clay-altered andesite and graphitic argillite. One such breccia, a quartz-ankerite breccia, intersected at a vertical depth of 22 metres, averaged 56.40 grams per tonne gold over a core length of 1.83 metres (Assessment Report 12434, page 14).

The mine dump is estimated to contain 1324 tonnes of material averaging 1.67 grams per tonne gold (Assessment Report 12434, page 9).

This deposit was mined by the Rabbitt brothers and Grasshopper Mines Ltd. between 1938 and 1941. A total of 1304 tonnes was mined averaging 25.7 grams per tonne gold and 14.0 grams per tonne silver.
