Mahogany Mountain and the associated volcanic craters of the Lake Owyhee volcanic field are in the Owyhee Mountains of Oregon just east of the Owyhee Reservoir on the Owyhee River.[3]

The southeastern end of the range including the old mining area west of Silver City is referred to as the Silver City Range.[4] About 8.3 kilometres (5.2 mi) west of Silver City is the De Lamar ghost town in Jordan Creek below the mine workings on De Lamar Mountain to the south.[4] The area was active in the late 1880s. In the 1970s mining began again with the development of open pit silver–gold mines on De Lamar Mountain.[5][6]
