The Burra Burra Mine is a copper mine located in Ducktown, Tennessee, in the southeastern United States.
 Named for the famous mine in Australia, the Burra Burra Mine extracted over 15 million tons (14 million metric tons) of copper ore during its 60 years of operation between 1899 and 1959.
 The mine's remaining structures are listed on the National Register of Historic Places as part of the Burra Burra Mine Historic District.
 The site is also home to the Ducktown Basin Museum, and the museum and mine are a Tennessee State Historic Site operated in partnership with the Tennessee Historical Commission.
Halobacteria (also Halobacteriacea) are a class of the Euryarchaeota, found in water saturated or nearly saturated with salt.
 Halobacteria are now recognized as archaea, rather than bacteria.
 The name 'halobacteria' was assigned to this group of organisms before the existence of the domain Archaea was realized, and remains valid according to taxonomic rules .
 In a non-taxonomic context, halophilic archaea are referred to as haloarchaea to distinguish them from halophilic bacteria.
Iron Mountain Mine, also known as the Richmond Mine at Iron Mountain, is a mine near Redding in Northern California, US.
 Geologically classified as a "massive sulfide ore deposit", the site was mined for iron, silver, gold, copper, zinc and pyrite intermittently from the 1860s until 1963.
 The mine is the source of extremely acidic mine drainage which also contains large amounts of zinc, copper and cadmium.
 One of America's most toxic waste sites, it has been listed as a federal Superfund site since 1983.
The Bingham Canyon Mine, more commonly known as Kennecott Copper Mine among locals, is an open-pit mining operation extracting a large porphyry copper deposit southwest of Salt Lake City, Utah, in the Oquirrh Mountains.
 The mine is the largest man-made excavation in the world and is considered to have produced more copper than any other mine in history – more than 19 million tonnes.
 The mine is owned by Rio Tinto Group, a British-Australian multinational corporation.
 The copper operations at Bingham Canyon Mine are managed through Kennecott Utah Copper Corporation which operates the mine, a concentrator plant, a smelter, and a refinery.
 The mine has been in production since 1906, and has resulted in the creation of a pit over 0.6 mi deep, 2.5 mi wide, and covering 1,900 acre .
 It was designated a National Historic Landmark in 1966 under the name Bingham Canyon Open Pit Copper Mine.
 The mine experienced a massive landslide in April 2013 and a smaller slide in September 2013.
Methylocella palustris is a species of bacterium.
 It is notable for oxidising methane.
 It is acidophilic and was first found in a peat bogs, representing a novel subtype of serine-pathway methanotrophs, for which a new genus was described.
 It is aerobic, Gram-negative, colourless, non-motile and its cells can be straight or curved rods.
 Strain KT (= ATCC 700799T) is the type strain.
Ferroplasma acidiphilum is an acidophilic, autotrophic, ferrous iron-oxidizing, cell wall-lacking, mesophilic member of the Ferroplasmaceae.
 "F. acidophilum" is a mesophile with a temperature optimum of approximately 35 °C, growing optimally at a pH of 1.7.
 "F. acidophilum" is generally found in acidic mine tailings, primarily those containing pyrite (FeS).
 It is especially abundant in cases of severe acid mine drainage, where other organisms such as "Acidithiobacillus" and "Leptospirillum" lower the pH of the environment to the extent that "F. acidophilum" is allowed to flourish.
Archaeal Richmond Mine acidophilic nanoorganisms (ARMAN) were first discovered in an extremely acidic mine located in northern California (Richmond Mine at Iron Mountain) by Brett Baker in Jill Banfield's laboratory at the University of California Berkeley.
 These novel groups of archaea named ARMAN-1, ARMAN-2 ("Candidatus" Micrarchaeum acidiphilum ARMAN-2 ), and ARMAN-3 were missed by previous PCR-based surveys of the mine community because the ARMANs have several mismatches with commonly used PCR primers for 16S rRNA genes.
 Baker "et al." detected them in a later study using shotgun sequencing of the community.
 The three groups were originally thought to represent three unique lineages deeply branched within the Euryarchaeota, a subgroup of the Archaea.
 However, this has been revised, based on more complete archaeal genomic tree, that they belong to a super phylum named DPANN.
 The ARMAN groups now comprise deeply divergent phyla named Micrarchaeota and Parvarchaeota.
 Their 16S rRNA genes differ by as much as 17% between the three groups.
 Prior to their discovery all of the Archaea shown to be associated with Iron Mountain belonged to the order Thermoplasmatales (e.g., "Ferroplasma acidarmanus").
Acidophiles or acidophilic organisms are those that thrive under highly acidic conditions (usually at pH 2.0 or below).
 These organisms can be found in different branches of the tree of life, including Archaea, Bacteria, and Eukaryotes.
A thermoacidophile is an extremophilic microorganism that is both thermophilic and acidophilic; i.e., it can grow under conditions of high temperature and low pH.
 The large majority of thermoacidophiles are archaea (particularly the crenarchaeota and euryarchaeota) or bacteria, though occasional eukaryotic examples have been reported.
 Thermoacidophiles can be found in hot springs and solfataric environments, within deep sea vents, or in other environments of geothermal activity.
 They also occur in polluted environments, such as in acid mine drainage.
Scytalidocarboxyl peptidase B, also known as Scytalidoglutamic peptidase and Scytalidopepsin B (EC 3.4.23.32 , obsolete names include "Scytalidium aspartic proteinase B", "Ganoderma lucidum carboxyl proteinase", "Ganoderma lucidum aspartic proteinase", "Scytalidium lignicolum aspartic proteinase B", "SLB") is a proteolytic enzyme.
 It was previously thought to be an aspartic protease, but determination of the its molecular structure showed it to belong a novel group of proteases, glutamic protease.

Question: What were the years of operation of the mine that a novel group of acidophilic archaea found at?
Answer: 1860s until 1963
