The Jake area is underlain by marine sedimentary and volcanic rock of the Upper Triassic Stuhini Group. The stratigraphy is intruded by Late Triassic granodiorite, Early Jurassic monzodiorite to gabbro (Texas Creek Plutonic Suite) and Triassic to Jurassic syenite to monzonite (Copper Mountain Plutonic Suite).

The Jake vein is a quartz-pyrite-chalcopyrite-galena vein following a small creek near the northern boundary of the JW property. It lies near the contact between the microdiorite and volcaniclastic rocks, striking east-west and dipping 66 degrees to the south. Sarabat reported the best chip samples 169 grams per tonne gold across 0.4 metre and 133 grams per tonne gold across 0.12 metre (Assessment Report 20844).

The Diorite vein is hosted within microdiorite approximately 170 metres south of the Jake Vein. It is a quartz-pyrite vein running along the north edge of a 10 to 20 metre wide zone of ankerite alteration, at its contact with relatively fresh microdiorite, and has been sampled along 200 metres of strike length. Widths vary from a few centimetres to less than1 metre and grades are generally low, but one grab sample assayed 74.2 grams per tonne gold (Assessment Report 20844).
