The property is located on the southeastern portion of Bowen Island, between Snug Cove and Seymour Bay. The property is underlain by metavolcanic and metasedimentary rocks of the pre-Jurassic Bowen Island Group. These rocks consist mainly of dark green andesites, white to light grey and purple cherty tuffs with minor quartzite, porphyry and limestone. Dioritic rocks of the Jurassic to Tertiary Coast Plutonic Complex occupy the southern portion of the claim group.

Minor pyrrhotite and pyrite are common throughout much of the rock. Copper mineralization is present in four zones, occurring in three areas in silicified and brecciated shear zones and in one area with massive magnetite and pyrrhotite. The shear zones strike 015 degrees and dip steeply to the southeast.

In 1913, two main mineralized zones were developed on the Emerald group. Mineralization consisted primarily of pyrite and chalcopyrite with minor associated malachite and azurite. At the Adit zone, an adit was driven for about 70 metres following the strike of a shear zone, which hosted copper mineralization, averaging between 2.4 to 3.0 metres in width. About 30 metres to the southwest, a 9.2 metre shaft was sunk on another similar mineralized zone.

In 1917, a trial shipment of about 9 tonnes of sorted ore assayed 3.38 per cent copper, 39.77 grams per tonne silver and 4.11 grams per tonne gold (Minister of Mines Annual Report 1917, page 297). In 1918, a 100 tonne mill was erected but other than trial runs, no production was recorded.

Production recorded for the Bowena (Emerald and Snug Cove groups), amounts to 54 tonnes of ore shipped in 1907 which produced 5,754 grams of silver and 2,268 kilograms of copper.
