The Tower showing is located at about 1870 metres on the summit of Mount Kobau, 35 metres southwest of the radio communications tower and 1.5 kilometres northwest of the Mak Siccar occurrence (082ESW004). The showing was located during reconnaissance mapping in 1990 by Azimuth Geological Inc.

Regionally, the Tower 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.

The Tower showing consists of a podiform zone of silicified and pyritic greenstone or diabase. Limonite and manganese alteration is widespread in this zone which is transected by numerous north- trending linears. Sample 105770 taken from this zone yielded 0.18 gram per tonne gold (Assessment Report 20638).
