The Ebb occurrence is located on a south facing hill north of Renfrew Creek, approximately 1.5 kilometres north- north east of the north shore of Fairy Lake.

The area, according to Muller, is underlain by an east trending band of rocks known as the Chert-Argillite-Volcanic Unit, of the Mesozoic Pacific Rim Complex. In this area, the rocks are reported to consist of deformed cherts, argillites, limestone, sandstone, pyroclastics and volcanic flows. In contact with the northern boundary of this band, are metamorphic rocks of the Mesozoic and/or Paleozoic Westcoast Complex.

Locally, gabbro and hornblendite (Westcoast Complex) are reported to contain pyrite, pyrrhotite, and chalcopyrite, along with significant amounts of cobalt and nickel mineralization. The nickel minerals pentlandite and violarite are reported.

In the same area, pyrite, pyrrhotite, magnetite and chalcopyrite are reported to occur in an epidote skarn.

In 1979 and 1984, M. Tavela completed programs of geochemical sampling, geological mapping and ground geophysical surveys on the area as the Ebb claim. In 1979, grab samples of mineralized ultramafic and gabbro outcrops assayed up to 1 per cent copper, 0.66 per cent nickel, 0.122 per cent cobalt and 1.5 grams per tonne silver (Assessment Report 8278).

In 2006 through 2010, Emerald Fields Resource and Pacific Iron Ore completed programs of rock and soil geochemical sampling and ground and airborne geophysical surveys on the area as apart of the Pearson project.
