The Blackjack West occurrence is located on the west bank of a western tributary of the Manson River, approximately 10 to 12 metres above the creek level (Assessment Report 2185). This occurrence has similar regional geology to that of the Jordi occurrence (093N 133).

This showing occurs at the contact between granitic rocks of the Cretaceous Germansen batholith and hornfelsed slaty rocks of the Middle Triassic to Lower Jurassic Takla Group. The plutonic rocks are foliated with the foliation being parallel to the contact as well as the cleavage of the hornfelsed slaty rocks. The strike is 130 degrees and dips 60 degrees to the northeast.

Molybdenite with or without quartz occurs in joints at this contact. The molybdenite seems to be present over a width of about 0.63 metre (Assessment Report 2185).
