The Good Hope occurrence is located on the west side of Bird Creek, 13 kilometres southwest of Nelson. The workings consist of 3 adits and the work dates back to 1911. A number of veins of variable orientation and with spotty mineralization were subjected to prospecting at various times and all are in the immediate vicinity of the Good Hope or Ophir veins.

The area is underlain by volcanic (lapilli tuff) and metavolcanic rocks of the Lower Jurassic Elise Formation, Rossland Group and metasedimentary rocks of the Lower Jurassic Ymir Group. The mineralization occurs along or near the contact.

Parallel quartz veins hosted in east striking fissures and conformable to the regional foliation occur within quartz-mica and quartz-mica-chlorite schist. Bands and lenses of quartz, with interbands of pyritic, siliceous schist are up to about 1 metre wide and strike 085 degrees with a dip of 30 to 45 degrees south. Pyrite and chalcopyrite is reported locally from various veins in the area and some free gold is reported from oxidized portions of the mineralized zones.

Samples taken over 0.06 to 0.30 metre from the footwall vein in the No. 3 adit assayed 61.7 grams per tonne gold, 89.8 grams per tonne silver and 1 per cent copper (Assessment Report 11554).
