Geology
“The old district in which the Thor Project is located was variously explored and mined for precious metals and turquoise in the early 1900s, but was not an important producer. Some exploration was done in modern times for porphyry copper and detachment-related gold by major companies, but no serious discoveries were made. During the 1950s uranium prospecting rush a significant number of REE-thorium occurrences were discovered in the district and in adjacent areas. Some of these were variously explored but apparently none were mined. The district has received little attention since.” (Hogge and others (2010))
