Capsule Geology

The London prospect is located approximately six kilometres southeast of Alta Lake on the northeast facing slopes of Whistler Mountain, adjacent to Garibaldi Provincial Park.

Underlying the area is a northeast trending roof pendant of metavolcanic rocks of the Lower Cretaceous Gambier Group, enclosed by plutonic rocks of the Jurassic to Cretaceous Coast Plutonic Complex. Gambier rocks include chlorite and sericite schist, argillite and minor limestone. Felsic porphyry of dacitic composition, much of it intensely altered, also occurs; it may or may not be part of the Gambier Group.

Mineralization is confined to a 50 metre wide zone on either side of the dacite porphyry-metavolcanic contact. Chalcopyrite occurs primarily as blebs in "knots" of quartz and chlorite up to 15 centimetres in diameter. Pyrite-chalcopyrite-magnetite skarn mineralization occurs within garnetiferous lenses replacing limestone or limey tuff at, or near, the intrusive contact. Disseminated pyrite is common within the schists.

A 158-metre adit was driven in 1915 and a second adit, 455 metres in length, in 1967-68. Reserves calculated in 1970 consist of 6,500,000 tonnes of 0.66 per cent copper (Property File - MacDonald, 1970).
