The Melore occurrence is located on Hill 60, approximately 1.75 kilometres east- north east of Mayo Lake.

The showing occurs near the west-northwest trending geological contact of the Devonian Nitinat Formation (Sicker Group) and the Mississippian to Pensylvanian Fourth Lake Formation (Buttle Lake Group), (Open File 1988-8). Several hundred metres to the north, Fourth Lake Formation rocks form a west-northwest trending contact with granodiorite of the Early to Middle Jurassic Island Plutonic Suite (formerly called Island Intrusions).

Locally, two rhodonite/pyrolusite "veins", striking 040 to 045 degrees and dipping 60 to 65 degrees west, occur within bedded andesite tuffs (cherty tuff?) (Nitinat Formation?) some 20 metres apart. The veins are 2 and 3 metres wide and extend approximately 5 metres each between two 120- degree striking, 30-degree north dipping shear zones. Approximately 25 per cent of each vein is rhodonite and the remainder is pyrolusite.

In 1982, SMD Minerals completed a geochemical sampling program on the area as the And claim. In 1989, the area was prospected by M.M. Pardek as the Melore claim. In 1991, a program of soil sampling and a ground magnetic survey was completed on the area as the Arbutus claim.

Another rhodonite occurrence is located about 1 kilometre to the north- north west of the above showing in an area of dacitic rock. It occurs mostly as jagged boulders between 0.5 and 1 metre in diameter. This area has been disturbed by the construction of a forest access road.
