Neal Hot Springs in Eastern Oregon, a potential resource uncovered by Chevron in 1979, is now in play. US Geothermal recently announced plans for a full-scale test drilling program that includes plans for a 1,000m (~3,500f) hole to determine the extent of the resource in the area. Geothermometer temperatures are predicted around the 150C (~310F) range.

US Geothermal has taken the Raft River project from prior exploration to commercial operation previously.
