The Cyan property is located approximately 17 kilometres north-northeast of Lac La Hache. It is readily accessible by way of logging roads from Highway 97 which runs north from Lac La Hache.

The Cyan property is underlain by andesites, basalts, calcareous tuffs and argillites of the Late Triassic Nicola Group (Assessment Report 23517 and 25650). Nicola Group rocks are intruded by the Late Triassic to Early Jurassic Spout Lake Intrusive complex, an alkalic intrusive suite ranging in composition from pyroxenite through monzonite to syenite, and from batholithic size to small intrusive plugs, dykes and breccia bodies. Granodioritic rocks of the Triassic to Jurassic Takomkane Batholith intrude Nicola rocks east of the property. Alkaline plateau basalts of the Miocene to Pleistocene Chilcotin Group.

Native copper mineralisation has been found in two locations on the property (Assessment Report 23517). It occurs as blebs in chalcedonic quartz amygdules associated with specular hematite in chloritised amygdaloidal basalts of the Chilcotin Group, and also in Nicola Group andesitic flows. Chalcopyrite and malachite mineralisation are also reported to occur in Chilcotin and Nicola rocks (Assessment Report 23517).

Interest in the Spout Lake area was triggered in 1966 when the Geological Survey of Canada released the results of a regional airborne magnetic survey which outlined an annular magnetic anomaly 10 kilometres in diameter in the Spout Lake area and which included the area underlying the Cyan prospect. Subsequently, in 1966 and 1967, Coranex Limited abtained anomalous results in follow-up stream sediment geochemical surveys and soil geochemical surveys in the area south of Peach Lake. Programs of geological, soil geochemical, magnetometer, induced polarization and prospecting surveys were undertaken in 1967 in the area south of Peach Lake, but mainly north of the Cyan prospect. This work resulted in discovery of the Peach (MINFILE 092P 002), Tim (MINFILE 092P 122) and other porphyry copper-gold occurrences north and east of the Cyan occurrence. Exploration work was dormant from 1973 and 1982, when Guichon Explorco Limited carried out a soil geochemical survey over portions of the area. In 1986, mineralisation was uncovered on a logging road at the Miracle Property (MINFILE 092P124) immediately to the north of the Cyan property. In 1993, the GWR Resources/Regional Resources Limited joint venture carried out an induced polarisation survey centred to the north of the Cyan property, and outlined a chargeability anomaly which extended onto the Cyan property (Assessment Report 23517). Mapping and prospecting by PMA Resources Incorporated (Assessment Report 23517) and Norian Resources Corporation (Assessment Report 25650) outlined copper mineralisation on the property.
