The Jim zone is located on a ridge approximately 1 kilometre south-southwest of the community of Port Renfrew.

The area, according to Muller, is underlain by a meta-greywacke-schist unit and an argillite- meta-greywacke unit, both of the Jurassic to Cretaceous Leech River Complex (Geological Survey of Canada Open File 821). The former unit consists of meta-greywacke, meta-arkose and quartz-feldspar biotite schist; the latter consists of thinly bedded greywacke and argillite, slate, phyllite and quartz-biotite schist.

Locally, two zones (Jim and HA) of mineralized dike swarms cutting slates and schists have been identified. The dikes vary in size from 0.02 to 4.0 metres, consist of alaskite or aplite to diorite and are intensely silicified. Traces of fine pyrite, from 3 to 5 per cent, with coarser grained, up to 5 millimetres in size, arsenopyrite are hosted by the dikes.

In 2013, four consecutive samples along 7.0 metres of the larger dike from the Jim zone yielded an average of 0.464 gram per tonne gold. An earlier rock sample is reported to have assayed 5.54 grams per tonne gold (Assessment Report 34028).

The HA zone is located approximately 300 metres to the south west of the Jim zone. In 2013, a 1.0 metre chip sample yielded 0.803 gram per tonne gold (Assessment Report 34028).

In 2013, the area was prospected by J.A. Stewart as the Lucky Day property.
