The Tick showing is located 25 kilometres southwest of Vernon, between Wood and Okanagan lakes.
Rhyolitic porphyry of the Eocene Coryell Intrusions intrudes Middle Jurassic porphyritic quartz monzonite of the informally named Terrace Creek batholith. Spherulitic and miarolitic textures in the porphyry indicate a high intrusion level. The intrusions cut metamorphic rocks of the Shuswap Terrane and are overlain with patches of volcanic rocks of the Eocene Penticton Group.
The K-feldspar porphyry hosts Tertiary, possibly Eocene, molybdenum mineralization. A 5-metre chip sample assayed 0.02 per cent molybdenite (Assessment Report 1694).
