San Rafael West

San Rafael Swell

Terra has secured agreements to earn up to a 100% interest in two strategic claim groups within the San Rafael Swell in Emery County, Utah. This acquisition provides the Company with near-surface uranium exposure in a low-risk U.S. jurisdiction with strong infrastructure and government support.

The San Rafael Swell is a large, uplifted anticline in east-central Utah, part of the prolific Colorado Plateau uranium belt. Uranium within the San Rafael Swell was mined from the late 1940s through the 1970s, before operations ceased due to a market collapse rather than resource depletion. The district remains highly prospective, with multiple historic workings, adits, and shafts still visible.
