thumb|upright=1.5|Geologic map of the Lakeview District, where Tb are Miocene basalt flows, and Qt are mine tailings. Uraninite and coffinite ore bodies occur in brecciated flow-banded rhyolite associated with an intrusive dome. In the mid-1950s, uranium mining claims were filed in the mountains north of Lakeview. However, only two mines, White King and Lucky Lass, were developed. In 1958, the Lakeview Mining Company uranium processing plant was built on the outskirts of Lakeview. The mill had the capacity to process 210 tons of uranium ore daily. The mill employed 50 people; another 120 people were employed at the two mines. The uranium plant closed in 1961."Site Description and History" (PDF), Lakeview, Oregon, Processing and Disposal Sites, Office of Legacy Management, United States Department of Energy, Grand Junction, Colorado, April 5, 2009.
