Work History
Staked as USA cl (Y37558) in Mar/70 by C. Carr and prospected by the Caltor Synd (Rayrock Mines Ltd, Ashland Oil & Gas Ltd, Canadian Independent Oil & Gas Ltd) in Jul/70.
Restaked as Crag cl 1-50 (YA47649) in Sep/79 by a joint venture between Eldorado Nuclear Ltd and Canadian Occidental Minerals, which explored with geochemical and radiometric surveys in 1980. In 1982, Eldorado changed its name to Eldor Resources Ltd.
Capsule Geology
The 1970 claims were staked on a biotite-muscovite-quartz monzonite intrusion of probable Early Jurassic age (unit eJqm) cutting Early Mississippian granitic augen gneiss (unit DMgg).
No evidence of mineralization was found by Caltor. The Eldorado staking covered areas where stream sediment sampling returned anomalous uranium values. Grid surveys identified four radiometric and six soil geochemical anomalies. The highest soil sample values (up to 400 ppm U) were obtained near a uraniferous spring.
