The ice house foundation is located adjacent to the powerhouse. The Anaconda Company used large quantities of ice to cool drinking water for those working underground.
The Iron Boys as Foremen; or, Heading the Diamond Drill Shift
Between the hoist house and the headframe stand three sets of idler towers constructed of riveted angle sections that were designed to keep the wire rope taut between the hoisting drum and the sheave wheel at the top of the headframe. Four large steel ore bins once stood below the headframe. The Mountain Con was active longer than almost all other Butte mines and reached the greatest depth. One of the earliest operations of Marcus Daly's Anaconda Mining Company, work at the mine began by Three years later, with a three-compartment shaft feet deep, the mine's work force of men pulled copper and silver ores from underground.
The flat pitch of the large vein gave the Mountain Con the heaviest hanging wall in the district's mines. In , with the main shaft feet deep, a second shaft was started southwest of the the first. The No. The mineyard also included, in , a large boiler house, a rope house for repairing cables , and wooden tramways which carried the ore from the hoisting works to bins.

With up to men working underground and 68 more on the surface, No. The early Twentieth century saw continued activity at the Mountain Con Mine. The mine remained a large employer - - over people worked underground and on top in In the Anaconda Company replaced the steam hoist with a Nordberg engine, which used compressed air Inspector of Mines ; ; Sanborn ; Anaconda Operating into the s, the Mountain Con was one of the last active underground copper mines in Butte.
By mid-century, the mineyard consisted of a steel headframe, a hoist house, a change house, large steel ore bins, and frame buildings. Southeast of the headframe, fan housings helped ventilate the deep workings. In the mids, with the main shaft about 4, feet deep, the Anaconda Company installed an extensive air-conditioning system at the lower levels.
The Mountain Con was one of the few shaft mines to remain open when open-pit operations began in In , the main shaft of the Mountain Con reached the depth of 5, feet. By this time, some of the ore from the Mountain Con, especially from the deep workings, was hoisted up the Kelley mine shaft. This continued until , when all underground mining in Butte ceased Sanborn , Mines Register , Anaconda , Corbett Thousands of mining artifacts surround the mine as part of the Museum's extensive collections. Today, the mine remains consist of four features: a headframe, a relocated steam hoist, a hoist house and a railroad.
The mine shaft is 3, feet deep and has a concrete bulkhead near the surface supported by a wooden frame. The Orphan Girl mine was a major silver and zinc producer in Butte from the late s until when it was finally closed by the ACM Co. The mine derived its name from its isolation from the other major mining properties in Butte.
On September 13, , Charles X. In the mine was acquired by the ACM Co. However, the mine was allowed to fill with water during a lengthy legal dispute with the Daly Estate over mine ownership. In the early s, ACM was finally able to pump out the underground and set to sinking the shaft to the 1,foot level. ACM also upgraded the mine by relocating the steel headframe from the Colorado mine and the electric hoist from the Hibernia Chaleen et al.
Between and , the Orphan Girl again remained idle. ACM was pulling all the zinc ore it needed out of their Elm Orlu mine. By , the Orphan Girl had produced over seven million ounces of silver, not Butte's richest silver mine, but a steady producer with a reputation for its comfortable working environment. The waste rock dump, located just west of the Orphan Girl, was built between the s and ; this makes it one of the most recent hard rock mine dumps on the Butte hill.
The Orphan Girl continued to produce zinc ore for ACM until , when the company permanently retired the working operations. A group of local citizens interested in preserving a part of Butte's rich mining history opened the World Museum of Mining on the Orphan Girl site in , incorporating the hoist house and head frame into the museum complex Chaleen et al.

The mine was discovered in by Dennis Leary, George W. Newkirk and the Porter Brothers. It was named after the Hon. Parrott, a local attorney. The complex ore removed from the mine was carried by wagon to Corrine, Utah to be shipped by rail to eastern smelters. Locally, experiments began to try to smelt the Parrot ore.
Joseph Ramsdale and William J. Parks erected a small blast furnace in Town Gulch in , but were unsuccessful. Charles E. Savage constructed a horse-powered arrastra that successfully treated the ore, but was financially a failure. In the fall of Dennis Leary and the Porter Brothers built a blast furnace that used a blacksmith bellows, but they were stymied by their lack of knowledge on metal fluxes.
Discouraged, the mine owners looked elsewhere and the mine languished Daly ; Warren William Parks was unwilling to give up on the mine. He continued to pour his own labor and limited money into the shaft. Because he capitalized his operation with paychecks from his own day-labor, progress was slow. His efforts were justified when he reached the foot level when he hit paying ore.
He had discovered Butte's first copper mine. He was also very lucky; the Parrott turned out to be the only mine in Butte with copper ore above the foot level. The mine was patented in May of by Dennis Leary, J. Talbott and Thomas Irvine. The 3-compartment shaft was reported to be the best ventilated shaft in Montana. Four years later, the Parrott employed men underground and 33 men on the surface. Below the foot level, the Parrott boasted Montana's only 4-compartment shaft. In , the shaft reached to 1, feet with men underground and on the surface. Connections were driven to the nearby Neversweat mine at the 1, and foot levels, to the Nipper at the 1,foot level and the Original No.
Hoisting was accomplished using a 2,horsepower Union Iron Works engine. By the work force increased again to men and the depth of the shaft reached 2, feet. The Parrott operated two compressor plants together capable of operating drills Weed ; Hogan ; Byrne The Parrot vein continued for almost 2, feet uninterrupted. Erubescite was the primary ore; pyrites were rare and of little consequence. The vein was composed of 30 percent copper and it was reported in that all the three previous year's ore averaged 12 percent copper.

The next year, Amalgamated boosted production quotas from 1. Later in the year the surface buildings, especially the hoist house, were damaged by fire. By October, a temporary hoist fire-proof of equal power and capacity was on line.

The damaged head-frame was replaced with a foot steel structure similar to the Diamond and High Ore head-frames. Other structures and equipment were also upgraded. During this period of primary production, to , miners extracted almost million pounds of copper from the Parrott Western Mining World - The foot steel headframe was removed and the shaft was converted into a concrete-lined air intake. The wooden headframe that straddles the Parrott shaft today, constitutes the only remaining headframe of its type on the Butte hill, although it was not the original headframe and was built around The Parrott was one of Butte's top copper producers during the district's period of national significance, to Montana Inspector of Mines Report ; ; ; ; ; Report of the Director of the Mine ; Gidel The Smoke House is one of Butte's most unusual mines.
The shaft, the only remnant of the mine, was sunk in the heart of Butte's business district.
The Smoke House lode was first claimed on April 16, The survey of the claim showed two shafts in addition to the discovery shaft. All work was on an undeveloped block on the south side of Broadway between Main and Wyoming. Nearly 20 years passed while ownership splintered and Butte's uptown built upon the claim Gray Interest in the mine suddenly resumed in March of when workmen excavating the basement of the Thorton Building on the north side of Broadway on Wyoming Street uncovered the rich Smokehouse vein.
Investors scrambled to gain controlling interest in the claim. By July, the Smokehouse Mining Co. A 1,foot shaft was planned. Because uptown Butte had seen extensive surface development, the only site available for a shaft was a small parcel across Broadway from the Thorton Building.

Operations were limited to a small vacant lot behind a shoe repair shop on Wyoming Street. However, the company was well capitalized and work on the two compartment shaft was initiated by a large force of men. The lead was expected to be hit at the foot level. An electric hoist was installed after reaching 50 feet. In March of a small stringer of copper was cut at the foot level. Two months later a foot cross cut was opened at the foot level, but workers encountered a large volume of water.
A month later work was again suspended, when the small electric hoist proved to be too small for the depth and loads. A horsepower motor capable of reaching feet was installed in August and work resumed. In October, the water volume exceeded the capacity of buckets and the pump. A new pump and water columns were ordered and a new cage was installed.
