Yankee Consolidated Mining Company (1898-1925)

Work started on the Yankee Consolidated as early as July 1898. By December 1898 the company's tunnel was into the hill 765 feet. Throughout 1898 and 1899, the only references were for the company's stock price and how well the stock was selling. There were no reports of any ore being shipped. There were two assessments against the company stock in 1899 and 1900, to finance the needed development of the property.

August 28, 1898
The Yankee Consolidated Mining company recorded two deeds for the two mining claims it had purchased from T. W. Sullivan. The two claims were the Yankee Lode, and the Yankee No. 2 Lode. (Salt Lake Tribune, August 28, 1898)

October 15, 1898
The Yankee Consolidated company recorded a third mining claim, the Yankee No. 3. (Utah County Democrat, October 15, 1898)

September 1, 1899
Upon the death of Timothy D. Sullivan, the mine's manager since it's incorporation, the board of directors elected his widow to fill his place on the board, and R. G. Wilson to replace Sullivan as manager. (Salt Lake Herald, September 1, 1899)

September 1, 1900
The Yankee Consolidated company held its annual meeting, with 99 percent of shares represented, including many residents from Eureka. The meeting resulted in a change of the board of directors and officers, with shareholders of large blocks of shares filling the needed positions. (Salt Lake Herald, September 1, 1900)

November 9, 1900
The Yankee Consolidated and the adjacent May Day mine settled their conflicting borders. The Yankee management acknowledged that they had trespassed and extracted ore from May Day ground, and paid $3,000 for the ore it took. The May Day company took the payment and benefited by the Yankee company having found a continuation of the rich ore vein that the May Day had already been working, hundreds of feet from where the May Day company was actively extracting and shipping. (Salt Lake Herald, November 9, 1900)

December 16, 1900
The Yankee Consolidated company went through a complete change of directors, officers and management, with P. A. H. Franklin being voted in as president and general manager. (Salt Lake Herald, December 16, 1900)

(Later in December 1900, one of the holders of a large block of stock, sued the former president, both of whom were residents of Boston. The subject of the suit was that the former president had knowingly wasted company resources by driving the tunnel into May Day ground. -- Salt Lake Tribune, December 22, 1900)

April 1, 1901
With so-called "Franklin syndicate" in control, the Yankee Consolidated company purchased the north half of the Humbug lode and and north half of the Humbug No. 2 lode from Jesse Knight, for a reported $250,000. (Salt Lake Tribune, April 25, 1901)

(The $250,000 paid by the Yankee Consolidated company for the Knight properties was raised by the sale of 250,000 shares of company stock, at a stated value of $1 per share. The 250,000 shares were in-turn issued to John E. DuBois of DuBois, Pennsylvania (2/3) and E. W. Genter of Salt Lake City (1/3). This transaction gave DuBois and Genter control of the Yankee Consolidated company, owning half of the outstanding shares. -- Salt Lake Herald, March 2, 1902)

(The actual purchase agreement was dated April 26, 1901. -- Deseret News, August 14, 1901)

April 6, 1901
An upraise of just 96 feet from the Yankee Consolidated tunnel gave access to a large body of valuable galena ore. (Salt Lake Tribune, August 6, 1901)

July 15, 1901
A deed was filed that conveyed from E. W. Genter of Salt Lake City, to the Yankee Consolidated company the north half of the Humbug mining claim, and that portion of the Humbug No. 2 mining claims that lay south of the south line of the adjacent May Day mining claim. The deed reserved for Jesse Knight, and his representatives, right of way through the Yankee Consolidated or Humbug tunnels for access to adjoining properties. (Deseret News, July 15, 1901)

March 30, 1902
Dr. Franklin owned the Mountain View, the Humbug, and the Yankee Consolidated companies, and intended to "unite the group" and work the group from the existing tunnel on the Yankee Consolidated property. (Salt Lake Herald, March 30, 1902)

April 29, 1902
A deed was filed that conveyed the Letta, Hawk, Sparrow, and Dove mining claims from P. A. H. Franklin, to the Yankee Consolidated Mining company. (Deseret News, April 29, 1902) (These four claims received their patents in April 1904.)

(The management of the Yankee Consolidated company was changed at the August 1902 annual meeting of stockholders. John DuBois was elected president, and P. A. H. Franklin was removed. DuBois personally controlled 226,000 shares of the company. Franklin personally controlled 1,100 shares, with his voting strength coming from voting 126,000 proxy shares. The owners of those shares apparently changed their support. There had been a gentleman's agreement that DuBois would support Franklin as president, and allow Franklin to vote the DuBois shares by proxy. But something not reported in the newspapers changed. The annual meeting was postposed three times during the first week of August 1902, as the difficulties were being worked out. Later reports from December 1903 reveal that under Franklin, the mine development was too restrained, i.e., spending shareholder money without obvious results. With a new superintendent installed in February 1903, development by way of multiple drifts, winzes and raises very soon found a large body of ore, which was reflected in the annual report of August 1903.)

August 4, 1903
With John DuBois as president, the Yankee Consolidated, during the previous year had shipped 5,373 tons of first-class ore, and 3,059 tons of second-class ore, bringing $102,516.53 in revenue for the company. In the six months between February 1, 1903, and August 1, 1903, the mine had shipped 2,113 tons of first-class ore in 68 rail cars, and 2.059 tons of second-class ore in 67 rail cars. (Deseret News, August 4, 1903, annual report)

(This ore was shipped by wagon and team north along roads over Burriston Pass and down through Knightsville to the railroad siding at Homansville, also known as Summit.)

(Also during 1903, a new compressor plant was installed. The new superintendent stated that there was enough second-class ore in view, including that still in the old workings, to keep a 100-ton-per-day concentrating mill busy for three years. The company owned a mill site less than a mile away, to which an aerial tramway can easily be built. -- Salt Lake Herald, December 27, 1903)

(During October 1904, the Yankee Consolidated company shipped 20 cars of ore to Salt Lake City smelters. -- Deseret News, November 1, 1904)

January 23, 1905
The annual meeting was held on January 23, 1905, the first one held on 18 months, during which no dividend had been issued. Company policy was that all income was to be spent developing the ore bodies, and that only enough ore was being extracted and shipped to pay expenses, with any extra income being accumulated in the company treasury as surplus to cover improvement and developments costs in the near future for the well-managed mine and mill that were planned. A new compressor plant had been installed, which allowed air drills instead of electric drills, at a considerable savings. The company had shipped 10,080 tons of ore, generating revenue of $182,024.85. One of the expenses was $1,300 for setting up a company-owned hauling operation. This left a profit of over $62,000. (Deseret News, January 23, 1905; Salt Lake Tribune, January 24, 1905; Deseret News, January 24, 1905)

January 30, 1906
The Yankee Consolidated announced that a mill would be built, beginning in April. The Uncle Sam company, adjacent to the Yankee Consolidated company, had put up a mill "a year ago" and the results have been very good. (Salt Lake Herald, January 30, 1906)

December 21, 1906
The Yankee Consolidated Mining company deeded the Leona claim to the Beck Tunnel Consolidated Mining company. (Salt Lake Herald, December 21, 1906)

February 21, 1908
"Yankee Consolidated officers yesterday confirmed the action of the directors of that company in taking over the Mountain View Mining and Milling company and the Lake View claim, both properties having been owned by John E. Du Bois, president of the Yankee. The acquisitions are paid for by increasing the capital stock of the Yankee Consolidated company from 500,000 shares to 1,000,000 shares. The ground acquired gives the Yankee just about twice the holdings on the strike of its main vein that it had before, thus virtually doubling its resources." (Salt Lake Herald, February 21, 1908)

(John DuBois, owned the majority of the stock in both companies, and was also president of the Yankee Consolidated company.)

(The purchase was first proposed in late November 1907. -- Salt Lake Tribune, November 15, 1907)

"The Mountain View company also turns $6000 in cash into the Yankee Consolidated Company’s treasury, which contained at the time of the consummation of the deal about $26,000." (Engineering and Mining Journal, Vol. 85, page 333)

February 29, 1908
"Yankee Consolidated -- The directors of this company have purchased the property of the Mountain View Mining Company. The capital stock of the Yankee company has been increased from 500,000 to 1,000,000 shares, the Mountain View shareholders accepting 350,000 shares of this new stock in payment for their holdings." (Engineering and Mining Journal, February 29, 1908)

December 31, 1924
"Mountain View Acquires Yankee Consolidated -- Control of the Yankee Consolidated Mining company, owning property adjoining the old Uncle Sam and the Chief Consolidated estates at Eureka, was acquired yesterday by the Mountain View Mining company, through acquisition of the interests of John E. DuBois of Pennsylvania, who for the last twenty-five years has owned control of the Yankee. It is the intention of the Mountain View company to start operations at once in the Yankee, according to Secretary Fred Dern. At present the Mountain View Mining company has about twenty sets of lessees operating in its ground. In a short time it is believed the number of lessees will be increased to thirty. The Mountain View property consists of the May Day and the Uncle Sam mines." (Salt Lake Tribune, January 1, 1925)

January 31, 1925
The International Smelting company leased an eastern portion of the Yankee Consolidated mine for a period of five years. The International company agreed to equip the Yankee shaft, which was 300 feet deep, with a hoist and other tools and equipment. The International company had also been "quietly tying up properties until it holds considerable territory to the north, east and south of the Yankee shaft." Leasing the Yankee ground gave deep access to these newly acquired parcels. The Mountain View company, which had recently purchased the Yankee company, had about 40 leasers working in the western portion of the Yankee ground. (Salt Lake Tribune, January 31, 1925; February 3 1925)

By May 1925, the International company had "tied up, either by purchase or by option, many claims to the east of the Yankee ground, giving them almost a unbroken strip of mineral land between the Yankee and the Tintic Standard." (Salt Lake Mining Review, May 15, 1925)

May 22, 1925
The Yankee Consolidated mine was "secured" by the International Smelting company. (Eureka Reporter, May 22, 1925; October 16, 1925)

(The Yankee Consolidated Mining company was controlled by the International Smelting company after 1925, but due to large numbers of outstanding minority shares, continued to be listed on the Salt Lake Stock Exchange.)

(During June 1958, the still active Yankee Consolidated and Mountain View mining companies each shipped 60 tons during the month. -- Eureka Reporter, July 4, 1958)

North Lily Mining Company Merger (1976-1981)

August 21, 1976
Although the property of the Yankee Consolidated Mining company was completely absorbed into the North Lily company in 1925 by ownership of the mining claims, the company itself continued because of the outstanding shares of stock that still existed. In August 1976, Anaconda proposed to merge all of its owned and controlled companies in the Tintic district, into a single company known as the North Lily Mining company, taking its name from the existing company. (Deseret News, August 21, 1976)

November 19, 1976
The stockholders of 16 of the 17 companies controlled by Anaconda voted to approve the merger into the North Lily Mining company. The holdout was the 16 percent of stockholders of the Dragon Consolidated Mining company who voted against the merger. (Deseret News, November 19, 1976)

May 18, 1980
Although the merger took place in 1976, a series of law suits were filed contesting the exchange values of the individual stocks of the 14 companies in the North Lily merger. On May 18, 1980, a legal notice was posted advising stockholders of the 14 companies, excluding the Dragon Consolidated company and the surviving North Lily company, to surrender their stock certificates to have them exchanged for the approved value in North Lily Mining company stock. (Salt Lake Tribune, May 18, 1980)

Big Hill Mining Company;
East Tintic Coalition Mining Company;
Empire Mines Company;
Eureka Bullion Mining Company;
Eureka Swansea Extension Mining Company;
