The Glasgow occurrence consists of a showing of minor copper-molybdenum mineralization, 200 metres east of Glasgow Lakes, south of Franklyn Arm of Chilko Lake.

It is not well-documented, being based on a map symbol on a claim map (Property File - Renshaw, R.E., 1975). This location is apparently on or close to the contact between a granodiorite intrusion and volcanic rocks. Both the intrusion and the volcanics are known to be mineralized locally with chalcopyrite and molybdenite (Assessment Report 8295). Supplementing this indirect information, the possible setting of mineralization at the Glasgow showing is given here.

The area west of the Glasgow occurrence is dominated by a differentiated biotite granodiorite to quartz monzonite intrusion of the Upper Cretaceous to Paleocene Bendor suite. The granodiorite was intruded into the Lower Cretaceous Tchaikazan River succession consisting of andesitic, dacitic and basaltic tuffs and breccias, and minor argillite (Geological Survey of Canada Open File 1163; Assessment Report 8295). Regionally strata strike northwest and dip moderately to steeply northeast, although their orientations may be modified by the intrusion.

The interior of the granodiorite contains widely-spaced fractures, between 0.25 and 1.0 centimetre thick, filled with quartz which is locally vuggy (Assessment Report 8295). They strike east and dip moderately north or south. Some veins contain weak chalcopyrite and molybdenite. This was interpreted as weak, porphyry-type mineralization.

The contact with the Lower Cretaceous volcanics is generally characterized by hornfelsing and chloritic alteration, and locally by gossanous zones due to the oxidation of disseminated pyrite and pyrrhotite (Assessment Report 8295). These sulphides may be accompanied by very minor chalcopyrite and molybdenite.

The Glasgow occurrence is located approximately on the contact between the granodiorite intrusion and the Lower Cretaceous volcanics. Thus, it could contain either or both of the mineralization types described above.

No significant values of copper or molybdenum have been reported.
