Overview
(The focus of this page is the surface workings of the Tintic Standard mine, as visible in photographs, as well as a general description of the mine, with minimal coverage of the geology and financial returns. Also to establish a timeline using sources not previously readily available.)
E.J. Raddatz became interested in the district about 1906 and acquired a major holding in what is now the Tintic Standard area. Raddatz reasoned that even though the surface rocks did not show promising deposits, there was a chance of discovery at depth. His ideas worked out and, despite the complex faulting and folding in the area, in 1916 he discovered the Tintic Standard deposit. It took two shafts and thousands of feet of drift and winze to make the discovery. Raddatz was amply rewarded. The Tintic Standard Mine went on to become one of the major lead-silver mines in the world.
The Tintic Standard discovery from the Tintic Standard No.2 shaft stimulated activity in the eastern part of the district. The Eureka Bullion, Iron King, Copper Leaf, Eureka Lily, Zuma and Apex Standard shafts were sunk in similar geologic zones. With the exception of the Eureka Lily, none led to an immediate discovery, although this would change.
Mining geologists attracted by the discovery of the Tintic Standard began to study the district. In the early 1920s, Paul Billingsly provided the skills that led to several valuable deposits. Based on Billingsly's work, a long drift was driven on the 700 level of the Tintic Standard Mine. This exploration work intersected the ore deposit that became the North Lily Mine. Similar strategies led to the discovery of the Eureka Standard mine.
During World War II, the United States recognized that in the event of a long war, new sources of raw material would be essential. The US Geological Survey spent 1942 – 1943 studying the East Tintic District. An exploration program seeking bodies of ore that did not show at the surface (known as "blind" ore bodies), was commenced towards the end of 1943. The work progressed slowly and by 1945, four areas had been defined.
Production from the East Tintic district slowly increased through discovery of new mines between 1921 and 1930, when production reached its peak. From that peak, production decreased to its low between 1961 and 1970. In 1971 the Burgin mine was opened, but closed in 1976.
From "The Mining Industry of Utah," published by the Salt Lake City Chamber of Commerce, 1947.
Tintic Standard was discovered in 1916 after one of the classic prospecting campaigns in the history of Utah mining. For 10 years prior to 1916, Captain E. J. Raddatz worked his claims on the east side which were slightingly referred to as "goat pasture." Throughout the trying search, Raddatz was forced to call upon his stockholders 19 times for assessments to continue the shaft down through the Rhyolite flow to the 1000-foot level and ore. Discovery of the Tintic Standard proved of great economic value to the state and from 1916 to the present time, has been one of its major producers.
While the old Tintic Standard No. 1 mine is still in production [as of 1947], efforts of the company are centered on development of other constructive enterprise. Jointly with the North Lily, the Eureka Lilly (a subsidiary of Tintic Standard) is developing an area of Eureka Lilly and Twentieth Century ground.
Tintic Standard Mine
(History of the original Tintic Standard mine is being researched and compiled.)
October 1, 1907
The Tintic Standard Mining company filed its articles of incorporation with the Salt Lake County clerk. Officers were E. J. Raddatz, president and treasurer; W. I. Snyder, vice president; H. G. Snyder, secretary. (Salt Lake Herald, October 2, 1907, "yesterday")
(Ira D. Travis did not become involved with Tintic Standard until 1913.)
(E. J. Raddatz had been superintendent of the Honerine mine and mill near Stockton, Utah, as early as late 1904, and was the "author" of the drain tunnel at that mine. He had been "connected with it for a number of years." This was the earliest refernce to Raddatz in online newspapers. -- Salt Lake Herald, January 1, 1905)
1907
The nucleus of the Tintic Standard was located by John Bestelmeyer. Captain E. J. Raddatz moved in and began development of the East Tintic area. The camp of Dividend was established at the Tintic Standard Mine. At this time, Mr. Raddatz selected the name of Standard, but when application was made for a post office, the application was not allowed because the name selected would be confused with Standardville in Carbon County. The name was selected by contest with a prize being awarded to the winning name of Dividend. (The Towns Of Tintic, by Beth Kay Harris)
The nucleus of the Tintic Standard group was located by John Bestelmeyer. In 1907, Bestelmeyer interested Captain E. J. Raddatz in the development of this East Tintic ground. Unlike the mines in the western and northern areas, the eastern range hid her ore bodies deep down under overlying porphyry. This formation was known as "heavy ground," and required careful mining and heavy timbering. Thirty million board feet of great timbers lined the mine below. (The Towns Of Tintic, by Beth Kay Harris)
Surrounding the Standard and in the same ore zone lay the North Lily, Eureka Standard, Eureka Lily, Eureka Bullion, and the Zuma. These five mines alone cleared for their owners over one hundred million dollars. (The Towns Of Tintic, by Beth Kay Harris)
1915
The Tintic Standard at 1000 feet hit bonanza in the year 1915. (Eureka Reporter, Thursday, February 16, 2006)
March 9, 1919
When the Goshen Valley railroad built its spur to the Tintic Standard mine at Dividend, it also built a 2.1 mile spur to the Iron King mine at a station the railroads called Iron King. (Salt Lake Tribune, March 9, 1919)
(The spur to the Tintic Standard mine was completed and was operated as the Goshen Valley Railroad until 1928, when it became the D&RGW's Goshen Valley Branch. The spur to the Iron King mine was called the Iron King Spur.)
March 9, 1919
Construction of the Goshen Valley railroad began in mid March 1919. The purpose was to serve the Tintic Standard and Iron King mines. Contracts had been awarded to Utah Construction company, with work to star before March 20th. The railroad was to extend from the Iron Spur siding on the railroad's Tintic Branch, two miles west of Elberta, then direct to the Tintic Standard mine, a distance of seven miles, with a 2.1-mile spur to the Iron King mine. With all the tracks and sidetracks, the total distance was to be ten miles. The grade of the new branch was to be 3 percent for the first four miles, then 4 percent for the remainder to the Tintic Standard mine. The rail to be laid was 80-pound rail. Upon completion the new railroad was to lease its locomotives and equipment from D&RGW. Other mines in the immediate area to be served by the new railroad included the Eureka Lilly, Eureka Bullion, Eureka Standard, South Standard, and the Apex Standard. The officers of the railroad were E. J. Raddatz, president (president of the Tintic Standard mine); C. E. Loose, vice-president (president of the Iron King mine; and W. I. Snyder, secretary. (Salt Lake Tribune, March 9, 1919)
March 30, 1919
"East Tintic to Have a Railroad", article about the Goshen Valley Railroad. To be built by Utah Construction Company to overcome a long haul by auto-trucks from the Tintic Standard mine. Officers were E. J. Raddatz, president, C. E. Loose, of Provo, vice president, and W. I. Snyder, secretary. Raddatz was also the manager of the Tintic Standard. (Salt Lake Mining Review, March 30, 1919)

A Lesson in Management -- The recent decision of the directors of the Tintic Standard Mining Co. to pass another quarterly dividend has aroused much speculation as to the condition of the company's affairs. Although no explanation accompanied the public announcement, we happen to know some of the facts. The mine, in the North Tintic district in Utah, contains large deposits of rich lead-silver-copper ore in limestone beds. It is a "young" mine, the first ore having been shipped only about five years ago. Since then dividends amounting to $1,715,000 have been distributed and an expensive milling plant and a standard-gage railroad from the mine to the mill, a distance of about ten miles, have been built at a cost said to have been nearly a million. All of this came from proceeds of the sale of ore.
A mine, however, can be overworked; it can be abused; and this is what was done to the Tintic Standard mine. The only concern of the management seemed to be the maintenance of current production. When the mill was completed, early in 1921, about four hundred tons of medium-grade ore was shipped daily in addition to the smelting ore. This necessitated the extension of the stopes from which the high-grade ore had already been taken, and the open areas became larger than ever.
The ground was "good" from the miners' standpoint, and huge square-set stopes were left unfilled. Finally, warning came in the form of several costly caves; others were imminent, and one of the shafts was threatened. It became apparent that a serious mistake had been made in allowing the stopes to remain virtually unfilled. The management realized, what it should have known all along, that the function of timbers in a mine is to serve as a scaffold from which miners may work; to afford temporary protection, and to maintain necessary passageways; they should not be expected permanently to support mine workings, particularly where the orebodies are large, as they are in the Tintic Standard.
For some months now many hundreds of tons of waste have been poured daily into the old stopes, and, we understand, danger of disaster is past. A new policy has been formulated; the greatest ultimate profit will be obtained from the property by doing systematic, if somewhat slower, mining. The mine will be put in good physical condition and will be kept that way. A disproportionately large expenditure will be necessary for some time, but in reality a considerable part of the current mining cost is a deferred charge on ore that was shipped many months ago.
Naturally, earnings have been decreased, and the decrease has been reflected in the passing of dividends and the decline of the price of shares on the exchange. We are informed, and we have every reason to believe, that the reserve of proved ore is exceptional and that the outlook for the future is excellent. A lesson has been learned; it was expensive, but lessons that are not expensive frequently are easily forgotten.
1934
"Another underground fire of seven years duration broke out
in the Tintic Standard Mine. Fire fighters from Butte, Montana, were brought in, and industrial safety practices now adopted and used throughout the United States were developed during this experience at the Tintic Standard." (Eureka Reporter, Thursday, February 16, 2006)
1934
It was from the top of the 1455 stope in this volcanic mine that fire was discovered. Mine fires are fearful things, diabolically hard to stamp out. They are nourished and fed by the gases which filter into the mine from subterranean sources, many of which are inflammable themselves. Timbers will smolder for weeks, then burst into flame. Smoke, combining with underneath gas, will render unconscious in a moment anyone encountering the deadly fumes. (The Towns Of Tintic, by Beth Kay Harris)
Bulkheads were put in, and thousands of tons of concrete were poured into the workings of the Tintic Standard in an effort to extinguish the fire, only to have it break out in other sections. This fire burned for seven years before the professional crews of fire fighters brought in from Butte, Montana, could stamp it out. During these seven years, rescue and first-aid methods were developed at the Standard that are now adopted work procedure in industrial plants all over the United States. (The Towns Of Tintic, by Beth Kay Harris)
1936
"The Tintic Standard entered the milling field. Their plant was
dismantled two years later." (Eureka Reporter, Thursday, February 16, 2006)
January 2, 1936
Tintic Standard buys Eureka Lily -- Control of the Eureka Lily Mining company was sold by the Chief Consolidated Mining company, to the Tintic Standard Mining company. The Chief Consolidated company held 61 percent of all Eureka Lily stock. The Eureka Lily comprised 15 patented claims situated on 127 acres. (Eureka Reporter, January 2, 1936)
Excerpts from the Eureka Reporter, January 2, 1936
The Eureka Lily is now shipping approximately 1,500 tons of gold, silver, lead ore per month. The bulk of the ore is being mined from the new Eureka Lily shaft, located in the southeast end of the ground. The Tintic Standard and Eureka Lily are connected by underground workings. A drift from the 1250 foot level of the Tintic Standard No. 2 shaft, connects the 1300 foot level of the Eureka Lily by a 50 foot raise in the former property.
Production from the Eureka Lily will be shipped via the 1250 level of the Tintic Standard and the No. 2 shaft of the Tintic Standard in order to eliminate a truck haul from the Eureka Lily shaft to the loading station.
The Tintic Standard company plans to begin immediately an extension of the drift on the 1400 foot level, which is now within 200 feet of the Eureka Lily shaft to make another outlet. In making this connection it will be necessary to deepen the Eureka Lily shaft an additional 140 feet, in addition to the 200 foot drift. When this connection is completed it will facilitate the movement of the ore from the Eureka Lily property.

November 18, 1937
Four subsidiaries of the Tintic Standard Mining company, including the Eureka Lily Mining company, East Tintic Consolidated Mining company, the Provo Mining company, and the Iron King Consolidated Mining company were consolidated into a new corporation to be known as the Eureka Lily Consolidated Mining company. The articles of incorporation were to be filed before January 1938. (Eureka Reporter, November 18, 1937)
January 13, 1938
The Tintic Standard announced that the silver section of the mine would be shut down due to the low price of silver on the market. (Eureka Reporter, January 13, 1938)
January 13, 1938
The Eureka Lily mine was closed "this week." All operations, both development and production of ore was stopped "the middle of last week." A few men were kept working doing cleanup and preparing the mine for shutdown. The remainder of about 70 men were laid off, without a known return date. The Eureka Lily mine was closed due to the low price of silver and other metals. Officials reported that the mine was working on such a low profit margin that the drop in the price of silver made it a money losing operation. (Eureka Reporter, January 13, 1938)
July 17, 1941
The Tintic Standard Mining company leased for a period of 10 years, 56 acres of North Lily Mining company ground, and an additional 56 acres leased from Eureka Lily company which was controlled by the Tintic Standard company. A one-mile drift was already nearly completed westward from the Tintic Standard main No. 2 shaft at the 1450 level, and crossing into North Lily ground. Any ore extracted was be removed by way of the Tintic Standard No. 2 shaft, and 50 percent value of any ore extracted from North Lily ground would be paid to the North Lily company. (Salt Lake Tribune, July 11, 1941; Eureka Reporter, July 17, 1941)
January 11, 1945
"Two of the state's larger mining companies have combined their efforts upon a program in the Tintic district, which is now entering its most interesting stage. The project, known as the Development Unit, was started in October 1941 under an agreement between the Tintic Standard Mining company and the North Lily Mining company, a subsidiary of International Smelting & Refining company. Work of the development unit was to sound out the ore production possibilities of an area consisting of 143 acres of ground in the East Tintic district, which includes parts of the Eureka Lilly Consolidated Mining company and Twentieth Century Mining company properties. The area, hitherto undeveloped at depth was regarded by geologists and engineers as one of the most promising areas in the Tintic district. Since 1941, more than 8,000 feet of lateral work has been done and several promising ore showings have been encountered. Work in the Development Unit is being performed from the 1450-foot level of the No. 2 Tintic Standard shaft. A drift has been extended southwesterly along what is called the South Fault, a mineral fault which has led to ore in other parts of the district. The drift is now out a distance of 8,000 feet from the No. 2 Tintic Standard shaft and well within Twentieth Century ground." (Lehi Sun, January 11, 1945)
December 3, 1948
"Operations on the 1500 and 1600 foot levels of the North Lily mine have been abandoned and the pumps pulled, F. A. Wardlaw. Jr., president, said last Wednesday. The gold-silver-lead-zinc ore being taken from those levels played out and chances for finding new ore were considered nil, he stated, so pumps were pulled and the levels allowed to flood. The mine had shipped several cars per month until about a month ago, Mr Wardlaw said. Work is being done on the 1100 and 1350 levels of the North Lily in connection with the development of a leased block in the property of the Eureka Lily Mining Co. However there have thus far been no extractions of ore from the leased area." (Eureka Reporter, December 3, 1948)
January 9, 1949
There were long delays in resumed operations at the Tintic Standard mine because of the change in the main hoisting shaft from the No. 2 shaft, to the No. 1 shaft. (Salt Lake Tribune, January 9, 1949)
April 8, 1949
"What promised to be one of the best strikes in the history of the Eureka Lily Mining operations had just been made on the 1200 ft level. The campaign of work which resulted in the opening of the ore on the 1200 level consisted of about 200 ft of drifting from the shaft of the North Lily, that distance being sufficient to reach the ground of the Eureka Lily Company. The ore was carrying 12 gold 12 ounces silver and 20 percent lead." (Eureka Reporter, April 8, 1949)
1949
"Owing to the exhaustion of ores, in 1949, the Tintic Standard, North Lily, and Eureka Lilly mines, and the adjacent properties mined from them, all ceased regular operations." (USGS Professional Paper 1024, 1979, page 92)
"Owing to the exhaustion of ores, the Eureka Standard mine became inactive in 1940, and in 1949, the Tintic Standard, North Lily, and Eureka Lily mines, and the adjacent properties mined from them, all ceased regular operations." (USGS Professional Paper 1024, 1979, page 92)
(Banner Mining company was organized in June 1916 by persons from Salt Lake City and Ophir, Utah, including Ernest Bowman, whose son, Allan B. Bowman was the then-current general manager of the Banner company. The elder Bowman had started his mining career in Ophir but had later moved to Arizona and New Mexico. The headquarters of the Banner company were moved from Oklahoma City, Oklahoma, to Salt Lake City at the end of June 1953. Control of the Banner Mining company was shared with the Rico Argentine Mining company, which itself was controlled by Salt Lake City interests, including the James A. Hogle invetsment group. Rico Argentine Mining company had been organized March 1912 by Salt Lake City associates, with operations in Rico, San Juan County, Colorado.)
June 11, 1968
Tintic Standard Mining company had the following subsidiaries: South Standard Mining company; Eureka Standard Consolidated Mining company; Eureka Lily Consolidated Mining company; Colorado Consolidated Mines company; Sioux Mines company. All were holding their annual meetings on June 12, 1968 in the Walker Bank Building in Salt Lake City. H. E. Raddatz was shown as president of all six companies, along with Banner Mining company, of which Tintic Standard held 11.37 percent. Total earnings for 1967 for all six companies with property in the Tintic district, leased to Kennecott, was $18,370, down from $29,658 the previous year. (Salt Lake Tribune, June 11, 1968)
(At some point between mid-1968 and mid-1970, the South Standard Mining company was no longer a subsidiary of, or controlled by the Tintic Standard Mining company, with the two companies only being mentioned together as part of the Unit Lease to Kennecott.)
(By June 1970, Tintic Standard Mining company was closely tied to Banner Mining company, with Tintic Standard owning 11.33 percent of Banner. H. E. Raddatz was president of Tintic Standard and Allan B. Bowman was a director of Tintic Standard and president of Banner. Banner Mining company held mining property near Tucson, Arizona. -- Salt Lake Tribune, June 10, 1970)
June 1970
Tintic Standard Mining company was planned to be part of a merger with Houston Gas and Oil Corp., along with Tintic Standard affiliates Rico Argentine Mining company and Consolidated Eureka Mining company. The merger was called off in June 1971. Consolidated Eureka held mining properties in Eureka, Nevada, not in Eureka, Utah. (Salt Lake Tribune, June 10, 1970; June 9, 1971)
June 10, 1970
According to the Salt Lake Tribune, June 10, 1970, the companies that were part of the Unit Lease to Kennecott included the following.
Chief Consolidated Mining company
Eureka Lily Consolidated Mining company
Eureka Standard Mining company
South Standard Mining company
Tintic Standard Mining company
(By June 1971, Harold E. Raddatz was still in control of the Tintic Standard company. And the Tintic Standard company was shown as being separate from the South Standard and Eureka Standard companies as part of the lease to Kennecott. -- Eureka Reporter, June 18, 1971)
1972
The Banner Mining company was merged into Amax, Inc., in 1972. Harold E. Raddatz was president of South Standard Mining Co., Eureka Lily Consolidated Mining Co., Colorado Consolidated Mining Co. and Sioux Mines Co." (Salt Lake Tribune, November 6, 1982)
(This resulted in Tintic Standard becoming part of Amax because of its 11 percent ownership of Banner.)
Tintic Standard Sold To Amax (1973)
1973
Amax Copper Mines company, a Nevada corporation acquired the Tintic Standard Mining company through merger in 1973. Allan B. Bowman was also president of Amax Copper Mines, a wholly-owned subsidiary of Amax, Inc., formerly American Metal Climax. (Salt Lake Tribune, December 31, 1974)
June 27, 1973
"Tucson, Ariz. - American Metal Climax, Inc. (AMAX) concluded agreements Wednesday to acquire Banner Mining Co. and Tintic Standard Mining Co. of Salt Lake City. In April, both Banner and Tintic shareholders approved the acquisition. But final agreement was contingent on the signing of a partnership arrangement between AMAX and The Anaconda Co. for the Anaconda company to operate an Arizona copper mining operation. Under that agreement, also signed Wednesday, AMAX and Anaconda created ANAMAX Mining Co., an equal partnership to operate and expand the Twin Buttes open-pit copper- mine in Pima County. Arizona." (Salt Lake Tribune, June 28, 1973; the reported price of the merger was $815 million)
(During Summer 1973, Tintic Standard Mining company and Banner Mining company were both delisted from the Intermountain Stock Exchange due to a merger with American Metal Climax. -- Salt Lake Tribune, September 6, 1973, "earlier in the summer")
E. J. Raddatz
Emil John Raddatz
Harold E. Raddatz
November 6, 1982
Harold E. Raddatz passed away at age 79. He was the son of E. J. Raddatz who developed the Tintic Standard Mining company. The abandoned mill on the east side of the Goshen Valley was at times known as the Harold Mill, named for Harold Raddatz. Raddatz was president of the Raddatz Corporation at the time of his death. He had been elected president of the Tintic Standard Mining company in 1949. The Raddatz corporation included, with Raddatz as president of each, the South Standard Mining company, the Eureka Lily Consolidated Mining company, the Colorado Consolidated mining company, and the Sioux Mines company. (Salt Lake Tribune, November 6, 1982)
(The death of Harold Raddatz in 1982 was what likley allowed Amax Arizona to take more control of the Tintic Standard and affiliated companies.)
Ira D. and Harriett D. Travis
Ira D. Travis, in 1909, was vice president of the newly organized North Beck Mining company. E. J. Raddatz was president. By 1913, Travis was on the board of the Tintic Standard company, with Raddatz as president. Travis continued as a director of the Tintic Standard Mining company through to November 1933 when E. J. Raddatz passed away. At that time, Travis was elected as president of the Tintic Standard company, a position he kept until his death on September 12, 1939 at age 80. Travis had been associated with Raddatz right from the earliest days of the Tintic Standard company and it affiliates in 1906. Travis and his wife Harriet Doolittle had married in 1893 in Albion, Michigan, where both had been attending college. (Deseret News, September 13, 1939)
In December 1939, Harriet D. Travis was elected to the boards of the Tintic Standard Mining company, and the Eureka Standard Mining company. She was the widow of Ira D. Travis who had passed away recently; he had been president of the Tintic Standard Mining company. She was reelected as a director as late as June 1956, but had passed away on August 16, 1962 at age 97, leaving her estate in charge of the 100,000+ shares she and her husband had held in the Tintic Standard company. In 1964, in a report of the activities of the Harriet D. Travis Charitable Trust, it was noted that she had been the last remaining heir to one of Utah early mining fortunes. (Salt Lake Tribune, December 8, 1939; August 17, 1962; Deseret News, March 3, 1964)
May 29, 1960
The South Standard Mining company was controlled by Harriet D. Travis, and the Raddatz estate. (Salt Lake Tribune, May 29, 1960)
South Standard Mine (1916-1996)
The South Standard Mining comany was organized in November 1916. The next year, after buying several adjacent mining claims and much smaller mining companies, its was idle. From then on it became a company that managed its ore reserves, wainting for another company to invest the badly needed funds to explore for more reserves.
By 1956, the South Standard Mining company was controlled by the Tintic Standard Mining company, along with the Eureka Standard Consolidated Mining company and the Eureka Lily Consolidated Mining company. But it was control only, by majority ownership of each company's stock.
(Read more about the Tintic Standard Mining company)
When Tintic Standard sold its holdings to Amax Copper company in 1973, the minority shareholders prevented South Standard being sold at the same time.
The South Standard remained independent, and in 1982 purchased the Eureka Standard Consolidated Mining company from Amax. The combined South Standard and Eureka Standard companies remained independent until they were sold to Chief Consolidated Mining company in 1995.
The South Standard had been one of four companies that formed the so-called "Tintic Group" that were party, along with the huge Chief Consolidated Mining company form the nearby Eureka area, to the so-called "Unit Lease" to Bear Creek Mining company, a direct subsidiary of Kennecott Copper Corporation. Kennecott first developed the Burgin mine on Chief Consolidated property, then the Trixie mine on Eureka Standard property. Because the entire area was under the unitized lease, all of the parties in the lease shared in the royalty fees.

Eureka Standard (1916-1983)
The Eureka Standard Mining comany was organized in November 1916. The next year, after buying sveral adjacent mining claims and much smaller mining companies, its was reorganized as the Eureka Standard Consolidated Mining company.
The company continued to absorb smaller companies throughout the 1920s and 1930s, but closed in 1940 after running out of economically available ore. From then on it became a company that managed its ore reserves, wainting for another company to invest the badly needed funds to explore for more reserves.
The Eureka Standard Consolidated Mining company was controlled by the Tintic Standard Mining company majority stock ownership from 1928 until 1974.
(Read more about the Tintic Standard Mining company)
In 1974, the adjacent Eureka Lily Consolidated Mining company, itself under similar circumstances of exhausted ore reserves, was sold and merged into the Eureka Standard Consolidated Mining company.
Then a month later, two afiliated companies, Colorado Consolidated Mines company, and the Sioux Mines company, along with the Eureka Standard company, were sold to Amax Copper Mines, a subsidiary of Amax, Inc.
Eureka Standard had been one of four companies that formed the so-called "Tintic Group" that were party, along with the huge Chief Consolidated Mining company form the nearby Eureka area, to the so-called "Unit Lease" to Bear Creek Mining company, a direct subsidiary of Kennecott Copper Corporation. Kennecott first developed the Burgin mine on Chief Consolidated property, then the Trixie mine on Eureka Standard property. Because the entire area was under the unitized lease, all of the parties in the lease shared in the royalty fees.
