The Star (L.1246A) occurrence is located at an elevation of approximately 1480 metres, 3.0 kilometres east-northeast of Little O.K. Lake and southwest of the Highland Valley Copper (MINFILE 092ISW012) open-pit in the southwestern Highland Valley.

The area is underlain by early Jurassic–late Triassic Guichon Creek Batholith Bethsaida phase quartz diorites. Faulting and shearing are extensive, the strongest direction being 115 to 120 degrees with moderate to steep dips. Other fault directions are 055 to 060, 095 to 100 and 135 to 140 degrees. Intense sericite alteration and oxidation is associated with faulting.

Locally, granodiorite and/or quartz diorite hosts disseminated and fracture-filling chalcopyrite, bornite, molybdenite and pyrite mineralization. Quartz veining with limonite and sericite alteration is also reported.

A surface chip sample is reported to have assayed 1.10 per cent copper and 0.03 per cent molybdenite over 5.7 metres (Assessment Report 537). To the northwest on the P.R. 5 claim, trenching is reported to have exposed disseminated copper mineralization over a width of 4.5 metres and length of 30 metres.

Diamond drilling, from west to east on the zone during the mid-1950‘s, is reported to have yielded 0.64 per cent copper over 12 metres in hole no. 1, 0.63 per cent copper over 5.4 metres in hole no. 2, 0.65 per cent copper over 17.7 metres and 0.38 per cent copper over 6.3 metres in hole no. 3 and 0.47 per cent copper over 4.5 metres and 3.65 per cent copper over 3.0 metres in hole no. 4 (Property File - Cominco Ltd. [1965-12-24]: C.G.'s, General Geology, D.D. Holes, Geophysics and Geochemistry Map - Bethsaida).

In 1967, diamond drilling on the Star claim yielded 0.13 per cent copper and 0.017 per cent molybdenum over 72.0 metres in hole no. 12 and 0.09 per cent copper over 73.5 metres in hole no. 13, whereas two other holes, located to the southeast on the north Grr. Fr. claim yielded 0.15 per cent copper over 54 metres in hole no. 11 and 0.21 per cent copper with 0.025 per cent molybdenum over 57 metres in hole no. 10 (Property File - Cominco Ltd. [1967-12-21]: Plan of Diamond Drilling & Geology and Valley Copper IP Anomaly - Bethsaida).

The area was originally staked in the early 1900’s as the Tamarack and Osprey properties and been explored in conjunction with the Bethsaida (MINFILE 092ISW042) occurrence. During 1955 through 1958, Bethsaida Mines completed programs of ground geophysical surveys, soil sampling, trenching and drilling. In 1963, Buttle Lake Minerals examined and completed a program of geological mapping on the area as the Bethsaida property. During 1965 through 1968, Cominco Ltd. completed programs of geological mapping, geochemical sampling, geophysical surveys and diamond drilling on the area.
