The Nioby 1 occurrence is located immediately east of Gentian Lake.

The area is underlain by Karmutsen Formation volcanic flows, pillow lavas and aquagene tuff overlain by Quatsino Formation limestone, all of the Upper Triassic Vancouver Group. These in turn are overlain by volcanic flows and breccias of the Lower Jurassic Bonanza Group. Intruding the stratigraphy is granodiorite of the Jurassic Island Plutonic Suite.

Locally, faults and shears in altered Bonanza volcanics are mineralized with pyrite and chalcopyrite. In 1983, a lone drill hole (No. 4) intercepted 1.5 metres of mineralization, yielding 0.7 gram per tonne gold and 17.8 grams per tonne silver from 12 to 13.5 metres depth (Assessment Report 12637).

In 1982 and 1983, Jentin Resources completed programs geological mapping, geochemical sampling and five drill holes, totalling 654.3 metres, on the area as the Nioby claims. In 2004, Hillsborough Resources completed a ground magnetometer survey on the area as the Bog property. This work identified a magnetic anomaly approximately 350 metres northeast of Hopo Lake on the Bog 3 and 4 claims.
