The showing lies on the west side of Crystal Mountain. Access is along Beaverdell Creek Road and then Crystal Lake Road.
The area is underlain by late Paleozoic Wallace Formation quartzite, greenstone and limestone, intruded by a late Triassic quart diorite/granodiorite intrusion (Paper 2008-1). Eocene quartz monzonite intrudes the older Triassic granodiorite and appears to be the main host for the Crystal mineralization. A north-northeast trending fault immediately to the west separates these rocks from Eocene Penticton Group conglomerate and siltstone of the Kettle River Formation and overlying alkalic volcanic rocks of the Marron Formation. A swarm of mafic dikes trend northeasterly through the Crystal claim.
Crystal mineralization comprises purple and green fluorite, associated with silica, clay and sericite alteration along a north-trending fault within the quartz monzonite. The zone also contains minor silver, as well as molybdenite along slickensided surfaces. A 40-metre long section averages 11.1 per cent fluorine over an average width of 2.2 metres. A 1.5-metre sample assayed 19 per cent fluorine, 0.017 per cent molybdenum and 2.8 grams per tonne silver (Assessment Report 19768).
Teck Explorations Ltd. conducted geological mapping and geochemical sampling of the area in 1989.
