The Fanny Joe and Sunnyside (82ESE160) claims are located 5.6 kilometres southeast of Greenwood, between 1300 and 1500 metres elevation, on the north side of the ridge 1 kilometre west of the summit of Mount Attwood. Access to the property may be gained by travelling 19.7 kilometres from Greenwood via the Lind Creek road or 13 kilometres via the McCarren Creek road.

The Fanny Joe (Lot 929s) claim was Crown granted to C.H. Tye in 1908. The initial target of exploration on the Fanny Joe was a 10-centimetre wide, steep easterly-dipping pyrite and galena bearing quartz vein, traceable on strike for 90 metres. Several open cuts and a 3-metre deep shaft was the first development. In 1933, the shaft was deepened to 6 metres where a considerable amount of manganese oxide was encountered. About 100 metres uphill a second similar vein was discovered.

In 1976, Silver Falls Resources Ltd. acquired the property and discovered three types of mineral occurrences on Sunnyside and the surrounding claims. The main zone consists of skarn mineralization associated with Permian Attwood Group limestone near the contact with a small granodiorite intrusion. A second zone, in the same limestone unit, contains galena, sphalerite, magnetite and chalcopyrite associated with quartz veins. A third zone, on the Bev 2 claim, consists of a 1.2-metre-wide shear structure containing pyrite and minor amounts of chalcopyrite and sphalerite, in silicified sedimentary rocks.

During 2008 through 2012, Grizzly Discoveries Inc. completed programs of soil, stream sediment and rock sampling, geological mapping and ground geophysical surveys on the area as the Overlander area of the Greenwood property.
