The Cebolleta uranium project in northwestern New Mexico is the site of five sandstone-hosted uranium deposits contained within the Jackpile Sandstone Member of the Upper Jurassic Morrison Formation. The uranium mineralization, which has been well-delineated by numerous drill holes, two open-pit and three underground mines, is a series of tabular shaped bodies that were deposited within individual sandstone lenses of the Jackpile Sandstone. Uranium deposits in the project area exhibit characteristics of “trend,” “redistributed,” and “remnant” types of deposits, as described elsewhere within the Grants mineral belt. Significant uranium resources are present in the project area.
