Overview
"Colonel Enos Andrew Wall, pioneer mining man and long a leader in the industrial life of the west. Few men, if any, had more to do with the mineral development of the west than did Colonel Wall. Born at Richmond, Wayne County, Ind., June 21, 1838, he came west to Colorado in 1860 and at once became interested in mining. After three years in Colorado, Colonel Wall went to Montana, where he continued his search for gold, but varied his mining activities with those of freighter and trader. After years spent in Colorado, Idaho and Montana, in mining, in 1885 he returned to Utah and engaged in mining at Mercur and other camps of the state. In 1887 he went to Bingham and there made a discovery which in time led to the organization of the world-famous Utah Copper company." (Enos Andrew Wall obituary)
The man many consider to be the father of copper mining in Bingham Canyon, Enos A. Wall, first visited the district in July 1887. He noted several outcrops of copper mineralization, a metal that was unimportant at the time. To follow his hunches, he staked the Mackintosh and Read claims. He bought other claims with similar visible signs of potential copper extraction, and by 1900 he had acquired 200 acres of claims. In May 1899, Wall sold a one-quarter interest in his claims to Captain Joseph R. De Lamar, with an option for the buyers to take an additional one-half interest.
The following comes from Utah, A Guide to The State, published in 1940.
The depression of 1893, which resulted in lowered silver, gold and lead prices, almost closed the [Bingham] camp. Samuel Newhouse and Thomas Weir of the Highland Boy built a cyanide plant in Carr Fork Gulch to extract gold, but large amounts of copper sulphide in the ore called for too much cyanide, and the plant shut down with terrific losses. Newhouse went East for money while Weir dug deeper, uncovering a vein of 18 per cent copper. The first shipment of copper ore was made in 1896. The Highland Boy was merged in 1899 with the Utah Consolidated, controlling interest being held by Standard Oil of New York; $12,000,000 changed hands, and John D. Rockefeller became one of the chief holders of the Utah mine. A smelter was built at Murray, but dissension with farmers forced the company to erect an aerial tramway from the mine to the smelter at Pine Canyon, near Tooele.
Meantime, Colonel Enos A. Wall was quietly buying copper holdings and relocating old claims around Bingham. Secret tests revealed that the ore ran from 3 to 40 per cent copper. By 1896 Wall had acquired 200 acres, spent $20,000 in exploration, and was ready to develop. Bingham wiseacres ridiculed Wall for his interest in copper, and referred to his holdings as "Wall's rocks." Wall, keeping his mouth shut, was experimenting for a process to extract low-grade copper at a profit. He met defeat at nearly every turn, but Captain Joseph De Lemar, an old friend, finally bought an interest and took a six months' lease for $375,000. Lemar brought two young engineers', Daniel C. Jackling, now (1940) president of the Utah Copper Company, and Robert C. Gemmell from Mercur to investigate the property.
Their joint report, published in 1899, changed the history of copper mining. Lemar took another option for $250,000, then lost interest. Jackling, convinced that large-scale surface mining was the only solution, interested Charles MacNeill and Spencer Penrose of the United States Reduction and Refining Company in his theory. A complicated, deal was made, which gave Wall $385,000 for 55 per cent of his stock, MacNeill and Penrose buying Lemar's fourth interest. The Utah Copper Company was organized in 1903, and the following year erected a pilot plant. Underground mining methods were used at first, but Jackling's insistence on surface mining bore fruit in 1907, when plans were made for steam shovel operation.
The following comes from The Porphyry Coppers by A. B. Parsons, 1933.
When in July, 1887, Col. Enos A. Wall first visited it, Bingham was a typical young mining camp. On this first visit to Bingham, he noted the usual signs of copper mineralization. Assays showed 2.4 per cent copper over a distance of 60 ft. along the adit.
Colonel Wall promptly staked two claims which he named in honor of two personal friends, Dick Mackintosh and Charles Read. The two were the nucleus of what became known as the "Wall's Copper Property.
During the next ten years the Colonel persistently added to his holdings. He located a few new claims and acquired others by purchase. By 1900 the group consisted of all or part of 19 claims covering an area of 200 acres. Meanwhile, he kept up the assessment work and financed further development. That is to say, he drove some 3000 ft. of adits into the hillside, following fractures and veinlets in the hope of finding larger masses of rich ore. All of these exploratory workings added to the evidence that the copper-bearing mass was very large.
The worthy Captain [De Lamar] in 1895 had a six-month option on a three-quarter interest in Wall's Copper Property at $375,000, which he did not exercise. Subsequently, in May, 1899, he purchased a one-quarter interest for $50,000 and took an option on an additional half interest for $250,000. But after spending $50,000 to do 2500 ft. of development work, he again dropped the option; and sold his one-fourth interest to Jackling and his associates for $125,000 [who later organized Utah Copper].
In 1899 Wall sold his interests in these earlier mines to Joseph De LaMar, who in-turn employed Daniel Jackling to further investigate the property. Jackling's proposal included open cut mining as the best low-cost method of mining the low-grade ore. Investors and funding sources were found and Utah Copper Company was organized in 1903. Utah Copper has its own history and story, but Enos Wall had more to contribute to mining in Bingham Canyon.
The following comes from the online Utah History Encyclopedia.
Enos A. Wall was born in 1838 in North Carolina and reared in Indiana. He began his mining career at Pike's Peak, Colorado, in 1860. He soon moved on to Montana, where he and a fellow miner began freighting goods between Salt Lake City and the Montana gold fields. Later, he became involved in mining in Silver Reef in southwestern Utah. In 1879 he met with financial difficulties in Silver Reef and he fled the area, taking with him his Silver Reef sweetheart Mary Frances Mays. They stopped in Salt Lake City to be married and went north to Wood River, Idaho, where he continued his mining career. He invented several pieces of ore crushing machinery and was elected to the Idaho Territorial Legislature. Six daughters were born to the Walls.
The family returned to Utah in 1885 and Enos engaged in mining at Mercur and elsewhere. Wall first visited the Bingham Mining District in 1887 and immediately detected signs of copper. At once he stalked three claims, and by 1900 owned all or part of nineteen claims, covering an area of two hundred acres.
In his attempts to gain financial backing for development of these low-grade properties, he approached Joseph R. DeLamar. Sometime later DeLamar obtained an option on a portion of Wall's holdings and had tests made by Daniel C. Jackling, then a young metallurgical engineer. Many negotiations ensured during the next three years until the Utah Copper Company was incorporated in 1903.
It was Wall's copper properties that netted him his vast fortune, although that venture was probably the most unpleasant and frustrating in his fifty-year mining career. He eventually sold his holdings, receiving $2,700,000 on the New York market. In 1904, Wall purchased a two story adobe home at 411 East South Temple, which had been built in 1880 by Mormon Bishop James Sharp. He hired architect Richard Kletting to transform the home into a palatial dwelling resembling a Renaissance villa. He lived the remainder of his life there, and on 29 June 1920 died of cancer at the age of eighty-one. Following the death of Mrs. Wall three years later, the home was bought by the Jewish community to be used as a social center. The building is presently occupied by the LDS Business College.
Enos Andrew Wall died in his home in Salt Lake City on June 29, 1920, at age 81. He was born in Indiana on June 21, 1839. He was buried in the Hollywood Forever cemetery, Hollywood, Los Angeles County, California. Cause of death was Adenocarcinoma (a form of cancer), with exhaustion contributing.
Enos Wall was an early user of the judicial system concerning the ownership and access to various mining claims. Various newspaper accounts of court proceedings put Enos Wall in Little Cottonwood canyon in Utah in 1871, 1872, and 1873, dealing with mining claims in that area. The 1873 item was also the earliest reference to his title as a Colonel. In February 1875, Wall was a party with George Clark, Charles Clark, and Charles Read, that recorded the Plymouth Rock mining claim in the Ophir Mining District, in Tooele County. In July 1875 he was party to a suit concerning the Mahogany No. 2 mine.
Other sources state that he left Utah and later returned. After his apparent return to Utah in 1878 or 1879, the reports of his activity in the courts serving the Silver Reef district in southern Utah, continued in mid 1879, 1880 and 1881. In late 1881 he apparently moved to the Wood River district in central Idaho, and early 1882 through to April 1885, he was superintendent of the Wood River Gold and Silver Mining company at Bullion, Idaho.
By 1890 he had returned to Utah, and was organizer and majority shareholder of the Ophir Hill Mining and Reduction company, indicating his activity in the milling and reduction of ore. The mining claims involved were the Miners Delight, Barlette, Burnette, Bannock and Weed Delirium, all in the Ophir mining district in Tooele County, Utah Territory. (Salt Lake Herald, September 16, 1890)
In 1895, Wall was the owner and operator of the Gold Belt mill at Ophir. (Salt Lake Herald, August 21, 1895)
In January 1896 Wall was one of the organizers of the Brickyard Gold Mining company at Mercur, Utah. (Salt Lake Herald, January 16, 1896)
It was Enos Wall who first discovered the low-grade copper ores found along the west side of Bingham Canyon, and he heavily promoted his own process for the concentration of the low-grade copper ores.
May 9, 1899
Enos Wall sold a one-quarter interest in his Wall No. 2 Group to Joseph De Lamar. This group of mining claim later became the basis for the Utah Copper property. (Salt Lake Herald, May 10, 1899, "yesterday")
Later in 1899, Wall registered the Keystone Fraction claim with the U. S. Land Office. This would later become a part of his Starless Group. Also in late 1899, Wall and DeLamar registered the Rudder Fraction, also in Bingham.
Previously, Wall had taken ownership of the Alliance Mining company in Park City, and in February 1900, Wall sold the Alliance claim to the Silver King Mining company, newly organized for the purpose and later to become one of the largest mining operations in Park City.
In April 1901, Wall took control of the Yampa mining claim in Carr Fork, and ten days later sold the claim to the Tintic Mining and Development company, which would later open the Yampa mine and build the Yampa smelter. In late 1901, Wall expanded his development skills to the Tintic District with the Sioux and Utah properties.
In mid July 1902, Wall took control of the Kempton claim. His association with the Kempton claim, and its close proximity to the claims and property of the United States Mining company in Galena Gulch in Bingham became part of a larger law suit to settle several encroachment and trespass claims against the U. S. company, or in-turn, against Wall and the other adjoining mining companies. Wall was among several operators with adjoining properties that were attempting to join in the U. S. company's success. The case continued into the succeeding years of 1903 through 1909, by various injunctions and other legal actions in the state district court, the federal appeals court, and the U. S. Supreme Court. Finally, in September 1909 the case was apparently settled out of court, in the favor of the U. S. company.
These events in 1903-1909 brought much attention to Wall, and his skills as a mining engineer and mine developer, especially with the success of the Utah Copper company, which was organized in July 1903. The almost immediate success of Utah Copper in bringing large amounts of Eastern capital to the Bingham District, also brought much prestige with Enos Wall. And he embraced the attention and became the apparent and anonymous source for numerous newspaper articles for the next ten years, concerning the glowing potential of all the Bingham mines.
It was during this period, in 1904, that Wall purchased his mansion on Brigham Street, which later became South Temple Street (see below).
In September 1905, Enos Wall sued to place an injunction against Utah Copper to prevent that company from building its own much larger mill at Garfield, that would use the Jackling-Janney milling process developed at their Copperton experimental mill. Since he was a major shareholder in the Utah Copper company, Wall wanted the company to use his own milling process and patents. Using the Wall patents had apparently been verbally agreed to in June 1904 when Wall's was voted off of the board of directors, but voted in as a vice president, and his share in the mining claims converted to common stock in the company. Utah Copper's response was that the Utah courts has no jurisdiction because Utah Copper was now a New Jersey corporation. The injunction was also to prevent control (51 percent) of Utah Copper from passing to Guggenheim's American Smelter Securities. (Salt Lake Tribune, September 9, 1905; Boston Evening Transcript, September 13, 1905)
From mid to late September, and early October 1905, it became a national story, carried in numerous newspapers across the nation, that Utah Copper and American Securities had been restrained in their grand plans by just one man, Enos A. Wall of Salt Lake City. The case went from the state Third District court, to an administrative chancellor judge in New Jersey, then finally on the docket of the New Jersey Supreme Court, to be heard on October 9th.
By late October 1905, the drama had ended, with Wall returning to Salt Lake City saying "that he had reached an understanding with the company for the settlement of their differences." The settlement meant that Utah Copper would be allowed to erect their new mill at Garfield, that they would be allowed to increase their stock from $4.5 million to $6 million, and that 51 percent of the stock would be held by the Guggenheims, who in turn would buy the half of the bonds issued to support the increased amount of stock. It was reported that Wall held 30,000 shares of Utah Copper stock, and that American Smelters would purchase all of his shares at $30 per share [$900,000]. (Salt Lake Telegram, October 25, 1905; Salt Lake Herald, October 25, 1905; Wall Street Journal, October 25, 1905)
(American Smelter Securities was a massive smelter trust controlled by the Guggenheims, with the actual smelters being owned and operated by American Smelting and Refining Company. -- See "Metal Magic," by Issac F. Marcosson, 1949)
"Col. Wall was elected a director of the company when it was organized in 1903, but he resigned in 1908, owing to friction with his colleagues on the board. This animosity was due, as far as I can learn, not to personal wrong but to intense disappointment, on the part of Col. Wall. in not being made manager of the company and in seeing the credit for the creation of the enterprise pass to Mr. Jackling, whose virile personality increasingly dominated the operations. One cannot withhold some measure of sympathy from the old miner, who stuck to his dreams so long and showed such patience in consolidating the property first, and then in nursing it during the long years that passed before his dream came true." (Deseret Evening News, December 20, 1919)
The following note about Enos Wall comes from the May 21, 1906 issue of the Salt Lake Telegram newspaper.
One of Utah's best citizens is Col. Enos A. Wall. Everybody knows Col. Wall and everybody is the friend of this splendid type of Utah citizenship. Ask every person that you meet and all will agree with you that the Colonel is one of nature's noblemen. He has done much for the upbuilding of the State and city. Since coming to Utah in 1868 Col. Wall has led an active life. Not only has he operated in this State, but for five years he was engaged in mining business in Idaho. The Colonel is a Hoosier and he is proud of it. Col. Wall is heavily interested in the Utah Copper company and other great Utah mining properties. His last public office was that of chairman of the Board of Public Works. He filled his place with credit to himself and profit to the city. Col. Wall is always interested in any proposition that will benefit the State and city.
With his increased financial resources from selling his interest in Utah Copper, Wall became a "capitalist" in residence in Salt Lake City. By mid 1908 he was placed on the boards of at least two local banks and the local Commercial Club, and became the subject of gossip as he became part of a group of persons making real estate investments throughout the city. Also by mid 1908, his wife had joined the social circles of the upper crust of Salt Lake City, holding "teas" at their home at 309 East South Temple Street. There were rumors of him building a new home, to be located also on South Temple Street.
Throughout this period, Wall continued to be active in the development of improved methods to process ore from the Bingham District, especially the low-grade copper ore found in the Utah Copper properties, as well as nearby properties, mainly his Starless mine that adjoined the Utah Copper group on the north. He regularly spoke and wrote about his process being better and more cost effective than the process that Utah Copper and Jackling had developed.
In early December 1909, Enos Wall sued Utah Copper for the value of 215,000 tons of ore, valued at $1,290,000, which he claimed had been illegally removed by Utah Copper company from the Amanda mining claim which he owned. The original suit was in Third District Court, and in June 1914, the suit was transferred to the United States district court. The case continued to be heard in several sessions, but was still undecided by late April 1916. On July 14, 1916, Judge Johnson of the U. S. court handed down his decision that Utah Copper was entitled to the ore that had been extracted because of the conflicting boundary lines between the Amanda claim (along the south edge of Wall's Starless Group), and several adjoining claims in the Charles Read group, owned by Utah Copper. In July 1917, Utah Copper admitted to taking the ore, and admitted to a value of $2,914, but also admitted that the cost of extracting the ore had been $2,179. (Salt Lake Herald, June 26, 1914; April 30, 1916; Ogden Standard, July 15, 1916; Salt Lake Tribune, July 28, 1917)
In January 1910, Wall and others attempted to stop the merger of Utah Copper and Boston Consolidated, arguing that the merged companies would control one-ninth of the world copper supply, and should therefore be subject to the Sherman anti-trust law. In a short period of two days, affidavits were taken and hearings held. The decision of the federal judges in the case, heard in New Jersey, came later on January 26th, declaring that only the federal government could file a case under the anti-trust law, and that any other concerns had been answered to the satisfaction of the court in the various affidavits. (Boston Evening Transcript, January 25, 1910, along with numerous other newspapers across the nation, all dated either January 25th or 26th, with weekly and semi-weekly newspapers following as late as January 30th)
During this period after 1910, Wall was shown as controlling the Daly mine in Park City, as well as other successful mines in Utah and Nevada. The mines in Nevada included Wall's ownership of large numbers of shares in the the well-known Consolidated Copper Mines Co., the Giroux Consolidated Mines Co., the Butte & Ely Copper Co., and the Central Mining Co., all of the Ely, Nevada, area of White Pine County, and active in the same porphyry ore bodies as the Nevada Consolidated Copper Company, another of the Guggenheim properties, which owned Utah Copper.
Enos Wall's wife was active in the suffrage movement, and two of their daughters both had official introductions to society, and later each daughter married in well-announced social events. Wall and his wife were regularly noted as traveling to New York, Washington D.C., California and "abroad" for extended periods of weeks at a time. Also during this period, Wall continued to be noted as being sued in cases involving the ownership of mining claims. He was also involved in a suit against Bingham City concerning the city allowing the flow of Carr Fork creek to become polluted with trash and sewage, thereby fouling the processes of his concentrating mill.
In February 1914, Wall sued the Bingham & Garfield Railway, and its parent company Utah Copper. The complaint was that the railroad had been allowed by eminent domain to cross his property at Bingham, but that the railroad was nothing but a dummy corporation of the copper company and not in fact a common carrier, and therefore not allowed to use the argument of eminent domain. The complaint also held that the railroad was a front for the copper company to simply steal any and all mining claims that it desired. The dumping of waste rock by the railroad was preventing Wall from extracting ore from that part of his property (the Starless mine), costing him a total of $10 million. The complaint also asked an additional $2 million as additional payment for the surface dumping rights it had already been using by temporary decree. The court's decision came in May 1914, finding that the railroad was not a dummy corporation, and that the railroad was entitled to use eminent domain. (Salt Lake Telegram, February 5, 1914; Salt Lake Herald, May 24, 1914)
There were apparently several eminent domain cases between Bingham & Garfield and Enos A. Wall. The above case in 1914 was one. Another was brought in November 1916 and settled in April 1917 when Utah Copper paid Wall $750,000 to purchase his Jay Gould and Alma groups in Carr Fork. This meant that instead of obtaining surface rights, the railroad and the copper company owned the ground outright. Wall refused to pay his lawyers their legal fees of over $22,000, but after the case went as high as the state supreme court in December 1918, with Wall changing law firms at least twice, he was forced to pay. (Deseret Evening News, April 11, 1917; Salt Lake Mining Review, April 30, 1917; Deseret News, December 11, 1918)
Wall's fight with Utah Copper and the Bingham & Garfield railroad continued in September 1919 when he sued to stop the railroad's use of eminent domain to cross his Starless Group of mining claims. His reason that such railroad line would "interfere with the removal of ore deposits from his property." (Salt Lake Herald, September 13, 1919)
June 29, 1920
Enos A. Wall died in his home in Salt Lake City on June 29, 1920, at age 81. He had been treated for cancer in Baltimore in mid February 1920. He was an active Mason and was buried on July 2, 1920 in the Mount Olivet cemetery in Salt Lake City. (Salt Lake Herald, June 30, 1920; Associated Press nationwide; Salt Lake Herald, July 1, 1920)
(Read the text of his obituary, published in the Salt Lake Herald, June 30, 1920)
Enos Wall died without leaving a will. On November 30, 1920, the probate court set the value of his estate at $979,851. His heirs were his wife, four daughters and one son. (Salt Lake Tribune, December 1, 1920)
(The Wall estate of almost $1 million in 1920 would be comparable to about $16 million in modern dollars.)
In February 1921, his wife as his heir, published a notice for the sale of some of his mining assets, including the Ashland, Nemesis and Mountain Gem lodes, all in Bingham. (Salt Lake Tribune, public notices February 12-24, March 6-14, March 19-28, 1921; final sale took place April 1st)
A decree in June 25, 1921 by the Third District Court, set Wall's estate at $1,467,144.81, made up of real estate and personal property, with liabilities of $44,357, and a state inheritance tax of $67,010.91. (Salt lake Tribune, June 26, 1921)
The last apparent asset of the Wall estate was the Starless mine, which was sold to Utah Copper in 1926. "In 1926 Utah Copper acquired the 110-acre Starless Group from the Wall estate, which contained some disseminated copper ore. This brought Utah Copper land ownership in the West Mountain mining district to nearly 1,000 acres." (Utah Copper Company 22nd Annual Report, 1926).
Patents
Beginning as early as 1887 while in Idaho, and later beginning in 1903 while in Utah, and until 1916, Enos Wall was actively receiving patents in the United States for mining processes and equipment. An online search finds at least 33 patents in this 1903-1916 time period. His partners during many of these patents were the Bemis brothers, George and Fred, two other mining engineers in the Bingham area who were also active in the development of ore milling processes.
His 1887 patent, while he was still at Bullion, Idaho, was for a certain type of crushing rolls.
His 1893 patent was for an "ore jigger" or concentrating machine. (St. Louis Globe Democrat, October 18, 1893)
(View the list of Wall's U. S. Patents, using the Google Patent search, dating from 1903 to 1916)
As he developed these new methods and machinery used to process ore, each had been initially developed in the former Dewey mill that he first leased in 1901, then purchased in 1904. He continued his efforts to economically reduce and concentrate ores from many of the Bingham mines. These Bingham ores included the well-known and plentiful lead-silver galena ore, and the high-grade copper ore from some of the underground mines. But his attention was focused on developing improved methods to process the low-grade copper ore.
Enos A. Wall Mansion
The following comes from the nomination for the Enos A. Wall mansion to the Utah Historic Sites Register.
This building is a good example of a well preserved classical revival structure. It was originally owned by Enos A. Wall, a successful mine owner in Utah and Idaho. Wall was born in Richmond, Indiana, in 1839. He had mining experience in Colorado and Montana before coming to Utah in 1868. Wall made headlines in Idaho in the 1870's and 80's where he was leader of the anti-Mormon political faction. In 1882 he was elected to the Idaho territorial legislature and was subsequently elected president of that body. Wall's anti-Mormon group was successful in outlawing polygamy in Idaho and preventing Mormon polygamists from holding public office there. After 1887 he primarily concerned himself with the Bingham Copper Mining District in Utah. He laid the foundation of the Utah Copper Company. He invented several mining related devises such as the Wall compressor. He died in this house in June, 1920. The house was sold to the Jewish Community Center in 1926. It served in that capacity until 1950 when it was sold to the Pacific National Life Insurance Company. In 1961 it was bought by the LDS Church and has since been used as the LDS Business College. In 1974 two rectangular additions (one on each side) were added and attached to the building by a corridor.
The following comes from an LDS Church press release dated August 24, 2016.
A historic mansion in downtown Salt Lake City has been renamed the Thomas S. Monson Center after the current president of The Church of Jesus Christ of Latter-day Saints. The Church donated the former Enos A. Wall Mansion that once housed LDS Business College to the University of Utah in 2014.
For the past two years, the mansion has undergone extensive interior and exterior renovation. The east building has been demolished and the original east entrance restored, and the gardens have been landscaped to create an added level of beauty to the area.
The refurbished 50,000-square-foot building will be the home to the Kem C. Gardner Policy Institute. The institute, located on the second floor, will develop and share economic, demographic and public policy data with business and community leaders. The mansion, located at 411 East South Temple, will also host community events on the first and third floors.
The building, completed in 1880, was originally owned by James Sharp, former University of Utah chancellor and mayor of Salt Lake City. In 1904 [sic: 1912], it was purchased by mining magnate Enos Wall, who hired renowned Utah State Capitol architect Richard K. A. Kletting to transform the mansion. Wall lived there until 1920. The building was used as the Salt Lake Jewish Community Center for several years until it was purchased by the Church in 1961. The Wall Mansion was home to LDS Business College from 1962 until 2006.
Starless Mine
From 1905 until his death in 1920, Enos Wall was actively promoting and developing the Starless mine, located on the north edge of the Utah Copper property, and close (on the east side) to the junction of Carr Fork and Bingham Canyon. Wall owned other mining properties in Bingham, and other locations in Utah, but held onto the Starless with hopes of it becoming a major producer of copper ore.
(Read more about the Starless Mine)
Wall Mill
In addition to the Starless mine, Enos Wall also leased and later owned two mills in Bingham. First was the Rogers mill, at its second location, which he purchased in 1901. He continued his ownership of the former Rogers mill from 1901 to 1904, at times leasing the mill to other companies to concentrate their own occasional shipments of low-grade lead-silver ores. He sold the Rogers mill in 1904, and purchased the larger Dewey mill.
After 1904, in addition to the Starless group of claims, Enos Wall also owned the 125-ton Dewey mill, that had been enlarged and remodeled in 1910. The mill in 1916 was equipped throughout with machinery of Col. Wall's own design, comprising Wall corrugated rolls, Wall steel rolls for middlings, three sets of jigs, two tables for concentrates, two Wilfley tables, and washers, of trough form, with valves and sprayers. Concentrates were discharged through the bottom and sands from the top. The mill had been in standby status since September 1915, with plans for operations to be resumed in 1916.
The Copper Curb and Outlook magazine of 1910 wrote, "Col. E. A. Wall, one of the richest mine owners of Bingham, after criticizing the Utah Copper company unmercifully for its alleged wasteful milling methods, has finished a plant that illustrates his own idea of efficiency."
