The Rob 19 area is underlain by metamorphosed Paleozoic (Permian and older) rocks of the Stikine Assemblage. These rocks are unconformably overlain by stratified Upper Triassic rocks of the Stuhini Group. This area lies on the eastern margin of the Tertiary-Cretaceous Coast Plutonic Complex.

A quartz-sulphide vein has been located in the southwest area of the Rob 19 claim exposed along strike for approximately 50 metres with apparent widths of up to 5 metres. One sample collected from the vein assayed 0.89 per cent copper, 4.6 grams per tonne silver and 60 parts per billion gold (Assessment Report 18462, sample 18514).

Mineralization consists of about 1 to 4 per cent chalcopyrite and about l to 2 per cent pyrite, The vein occurs within an area of complex geology and is situated at a contact between limestone and clastic sediments 50 metres west of a large feldspar porphyry plug. Other smaller veins have also been located in the area.

In 1988, Consolidated Bel-Air explored the Rob 17, 19, 20 and 21 claims by linecutting, soil (426 sample), silt (2 samples), and rock chip (19 samples) sampling, prospecting, and geological mapping.
