The Apex showing is located at about 1870 metres on the summit of Mount Kobau on the northwest banks of Mak Siccar Brook, 2 kilometres northwest of the Mak Siccar occurrence (082ESW004).

The showing was relocated during reconnaissance mapping in 1990 by Azimuth Geological Inc., approximately 50 metres east of a radio communications tower.

Regionally, the Apex showing is hosted by polydeformed regionally metamorphosed sedimentary and volcanic rocks of the Carboniferous to Permian Kobau Group. The aereal distribution of Kobau Group rocks is restricted by the Similkameen River to the west and the Okanagan fault to the east. Intruding these rocks are small granodiorite plugs of the Middle Jurassic Similkameen intrusion, lying along the Manery Creek fault. A pluton of the Similkameen intrusion is located 1.5 kilometres to the southwest. Post-Middle Jurassic pyroxenite is also found at the Mak Siccar deposit.

The Kobau Group rocks have been subdivided into up to nine units. However, these generally consist of chlorite schist, foliated greenstone and lesser quartz sericite schist. The Kobau Group rocks have a northwest trending schistosity as well as a major northwest trending fold axis. Shears cut these rocks in three directions: north-south on the eastern portion of the property, and northeast and northwest to the west.

A 0.50 to 0.75-metre wide quartz vein trends northeasterly across the summit of Mount Kobau. At the northeast end of the vein it has been exposed over 2.5 metres by the Apex adit. Here the vein pinches and swells dramatically. The veins strikes 250 degrees and dips 75 degrees to the north. Narrow, north-trending faults have resulted in minor displacement of the vein. Forty-five metres to the southwest, the vein is exposed in a small roadcut. Here, the vein is 0.60 metre wide and trends 225 degrees. The vein is hosted in massive quartzite.

Select samples yielded elevated gold, silver and copper values. Grab sample 105664 was taken from a pyritic quartz vein with minor limonite. Geochemical analysis yielded 0.21 gram per tonne gold and 1.1 grams per tonne silver. Sample 105662 was taken across 1.15 metres from the adit roof at the portal. The material, consisting of limonitic quartz, yielded 0.40 gram per tonne gold and 0.0014 per cent copper (Assessment Report 20638).
