Battle Mountain is located at the confluence of two rivers, the
Humboldt and the
Reese. The town is in the Humboldt valley between the
Shoshone Range to the southeast, the
Battle Mountains to the southwest and the
Sheep Creek Range across the Humboldt to the north. According to the
United States Census Bureau, the community has a total area of , all land.
Geology Copper mining started in 1866 and the Copper Canyon Mine operated from 1917 until 1955. The Tomboy-Minnie
ore deposits were developed after the depletion of the West ore body, which was developed after the depletion of the East ore body.
Open-pit mining started in 1967.
Placer gold was discovered in 1912. Mining switched from the copper-gold-silver ores to gold-silver ores in 1979. The Fortitude gold-silver
skarn body was discovered in 1981. The Surprise gold deposit was discovered in 1986. The economic geologic zone is primarily in the Antler
Sequence, consisting of the
Middle Pennsylvanian Battle
Formation, the Pennsylvanian to
Permian Antler Peak
Limestone, and the Permian Edna Mountain Formation. These
Paleozoic rocks were
intruded in the
Tertiary by a
granodiorite porphyry which generated the ore bodies as zones of disseminated
sulfide minerals. These zones include copper-gold-silver next to the granodiorite, followed by a gold-silver zone, then a lead-zinc-silver zone. and a 1.4-pound (630-gram) fragment was sent to NASA's
Jet Propulsion Laboratory for analysis.
Climate Battle Mountain's climate is
cool semi-arid (
Köppen climate classification BSk), receiving just enough precipitation to avoid arid classification. Due to aridity and high elevation, the area commonly experiences large
diurnal temperature variation, particularly in summer, when it averages almost . The monthly daily average temperature ranges from in January to in July. There are, on average, fourteen afternoons of or hotter maxima, 74 afternoons of or hotter maxima, eleven afternoons where the high does not rise above freezing, and seven mornings falling to or below annually; the average window for freezing temperatures is September 16 to May 29. By far the coldest recorded month has been January 1949, with a mean of and a mean minimum of – between January 2 and February 3, the temperature did not reach freezing, whereas during the winter of 2011/2012 every single day topped freezing. The hottest month has been July 2013, with a mean of and a mean maximum of , although July 2007's maximum was even hotter at . With a period of record only dating back to 1944, extremes range from on December 22, 1990, up to on July 12, 2002. The mean seasonal snowfall of on average occurs from November 25 to April 2, with half the annual snow falling during December and January alone. The snowiest season has been from July 1992 to June 1993, with a total of , whereas only fell from July 2014 and June 2015. Total seasonal precipitation has ranged from between July 1997 and June 1998, down to only between July 1958 and June 1959. ==Demographics==
