From project objectives: The Sonora Pass region was identified by the U. S. Department of Energy (DOE) as a potential uranium resource area because of past uranium production at the Juniper Mine and reported high-grade occurrences in other buried fluvial channels which are Tertiary in age. The objective of the Sonora Pass drilling project was to obtain subsurface data that would increase the accuracy of uranium reserve estimates for the project area.
