The Opole occurrence consists of two mineralized quartz vein samples from a mountain stream area west of Kitsumkalum Lake, 31.5 kilometres northwest of Terrace, B.C.

The Kalum Lake showing area is underlain by Upper Jurassic to Lower Cretaceous sediments of the Bowser Lake Group comprised mainly of argillite, greywackes and conglomerates. Generally, the sediments strike west and dip 75 degrees to the north. Stocks comprised of granodiorite, diorite and quartz monzonite of the Late Cretaceous to Tertiary Coast Plutonic Complex intrude the Bowser Lake sediments. High grade gold-bearing quartz veins fringe the Allard stock near its contact with Bowser Lake Group country rocks. The stock consists of hornblende-biotite granodiorite to diorite. The Allard stock is also described as a composite pluton with an eastern syenitic phase.

In 2019, Gold Fountain Resources Inc. undertook a program of rock, soil, and silt sampling on their Kalum Gold property, resulting in the discovery of two new gold showings (Poznan and Opole). Rock samples KA-4 and KA-10 from the Opole occurrence returned 1290 and 3874 parts per billion gold accompanied by highly anomalous arsenic of more than 10,000 parts per million and elevated lead values of 134.8 and 870.9 parts per million are associated with 30 to 40 centimetre wide fault zone (Assessment Report 38630).
