Colorado Mining Company

(The focus of this page is the surface workings of the Colorado 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.)

J. William Knight, in his book "The Jesse Knight Family," published in 1941, tells the following story about the strike at the Colorado mine.

He later acquired the Colorado property which adjoined the Beck Tunnel on the south. He began sinking a new shaft on this property and building an ore house at the same time, feeling certain that he would encounter the ore and would save time by being ready for shipment. He was not disappointed in his calculations in this venture. Both the shaft and the ore bin seemed to be properly located, and rich ore was soon on its way to the smelters.

The Colorado vein was first encountered by means of a shaft which was sunk to the two hundred and fifty foot level. At this point we broke into a beautiful cave, the roof of which was cemented tightly together with beautiful lime crystals of every imaginable shape and color. The bottom of the cave was solid carbonate lead-silver ores that could easily be dug into with the toe of a boot. The average width was about thirty feet and from forty to fifty feet in thickness. One could walk in the cave a distance of one thousand feet on top of this clean rich sand carbonate ore that was free from waste, resembling in a way, wheat in a bin ready for the market. This ore was mined by means of a drift driven underneath the ore, and raises made at various points allowing the extraction of the ore with very little labor-costs or other expense.

December 2, 1898
"The Colorado Mining company, also owning property in Tintic district, was incorporated in Salt Lake City yesterday, with a capital stock of $125,000, in shares of 50 cents each. The company has the following mining claims situated in Tintic Mining district: The Colorado, the Butte and the Morning Star. The following are the officers: George W. E. Dorsey, president; Albert Hagen, vice president; Daniel S. Spencer, secretary; Josiah Barnett, treasurer; these with Joseph Wilson, form the board of directors." (Salt Lake Herald, December 3, 1898)

From the Salt Lake Herald, December 4, 1898.

After making a number of visits to Tintic district and after examining a number of promising properties presented for his consideration, Major George W. E. Dorsey has succeeded in getting in on a gilt-edged proposition in the Colorado group, the incorporation of a company for the operation of which was chronicled in yesterday's issue of The Herald.

The Colorado group of claims was located several years ago by that veteran miner and prospector, Joseph Wilson, who, in the past, has been identified with the history of some of the leading producers of the camp, either as locator or part owner.

Wilson is convinced that the new Colorado company encompassed an extension of the Humbug and Sioux Consolidated vein, the ledge being easily traceable through the Colorado company's holdings. There are two well-defined veins running through the property for a distance of 2,900 feet, surface croppings from which have returned metallic values of from two to twenty-four ounces silver and $2 in gold, while from the bottom of the 100-foot shaft already sunk in the exploration of the group, values of twenty ounces in silver and $5 in gold have been obtained.

The ledge can be traced from the Godiva through the Uncle Sam, the Humbug, the La Reine, the Colorado, the Sioux Consolidated, and on to the Star Consolidated, on the other side of the divide, the Godiva, Uncle Sam, the Humbug, the Sioux Consolidated and the Star Consolidated having already made enviable records as heavy producers of the precious metals.

Two shifts are now engaged in opening up this property, and within the next few days additional men will be employed in pushing development work, and at the same time comfortable winter quarters are being erected on the ground, it being the intention to put in a steam hoist as soon as the work advances to a point requiring additional hoisting facilities.

The incorporators and directors being as follows: Major George W. E. Dorsey, president; Albert Hagen, the Mammoth merchant, vice president; Josiah Barnett, cashier McCornick bank, treasurer; Dan S. Spencer of the Oregon Short Line, secretary, and these, with Joseph Wilson, the original locator of the claims embracing the group, constitute the board.

June 4, 1904
"Orders for stock in the Colorado Mining company, having property adjoining the La Reine at Tintic, continue to be received by brokers and 2 cents a share is freely bid for it. It is the impression that Uncle Jesse Knight is after the control of the property in order that it may be included in the Bullion-Beck Tunnel-La Reine consolidation." (Salt Lake Herald, June 4, 1904)

December 20, 1905
The offices of the Colorado Mining company were moved from Salt Lake City to Provo. Jesse Knight was shown as president as part of the first notice of the special stockholders meeting, dated October 18, 1905. (Deseret News, October 18, 1905; Salt Lake Herald, December 21, 1905)

December 30, 1905
The Colorado Mining company filed its articles of incorporation with the Salt Lake County clerk on Saturday December 30th. Jesse Knight is president; Jacob Evans, vice president; Lester Mangum, secretary-treasurer. (Salt Lake Tribune, January 1, 1906)

(On January 5, 1906, the original Colorado Mining company re-filed its articles of incorproation, originally filed on December 2, 1898. -- Eureka Reporter, January 5, 1906)

July 9, 1906
Through a series of property filings in Provo on July 9th, the Colorado Mining Company increased its holdings to twelve claims. This bridged the gap between Jesse Knight's Beck Tunnel and Carisa properties. (Salt Lake Herald, July 10, 1906)

Summary of the article:

The Colorado Mining company was an old organization was incorporated in 1898 upon four claims adjoining Beck Tunnel territory on the south.
Nothing much was ever done by the Colorado company, but when the Beck Tunnel company's big strike was made a few months ago Knight decided it was time to act. He was convinced that the Beck Tunnel vein passed through the Colorado company's territory, and stated that development work to prove it had already commenced. A shaft had been located and started about 1,900 feet south of where the big ore bodies in the Beck Tunnel property were being mined, and Knight declared that this new shaft for the Colorado company was going to open up another bonanza mine in the Tintic district.
A group of deeds were filed in Provo on July 9th for twelve claims which cover the distance between the Beck Tunnel company's La Reine and the possessions of the Carisa company. The article lists several whole and fractions of mining claims deeded to the Colorado company, including:
Last Chance, Spy No. 2, Spy No. 4 and Red Bird claims, already held by Jesse Knight, plus the majority fraction of the Spy No. 3, and the majority fraction of the Phoebe S., for "$1 and other valuable considerations."
Spy No. 3, Jesse Knight already owned most of this claim, and purchased the fraction held by John Van Wagnen for $2,000.
June Bug and Phoebe S. No. 2 claims, Jesse Knight already owned most of these claims, and purchased the fractions held by Reed Smoot for $1,600.
Five acres of ground adjoining the Phoebe S. lode, from the Northern Spy Mining company for $9,000.
Water Rights: The company also secured a two-thirds interest in the Peterson spring from Mrs. H.P. Anderson, a vital resource for mining operations.

The Colorado Mine, located in Utah's Tintic district on Godiva Mountain, has rapidly become one of the most successful dividend-paying mines in the West. Backed by "Uncle" Jesse Knight of Provo, the mine is a standout example of his successful industrial ventures. (Utah County Democrat, April 15, 1908)

Summary of article:

Miners initially struck ore 250 feet down and 70 feet east of the main shaft. They followed a massive vein 490 feet south, revealing a face 40 feet wide with vast reserves still in sight.
The mine faces a "superabundance" of ore. The product, a loose sand carbonate, frequently slides down and fills the drifts, making it difficult for miners to move forward without being "caved upon" by wealth.
A new double-compartment shaft is being sunk 750 feet north of the original to connect with the Beck Tunnel and increase efficiency.
The mine currently employs 35 men and ships roughly 30 tons of ore daily, though management notes this could easily scale to 200 tons if production restrictions were lifted.
The ore is high-grade, generally valued between $75 and $100 per ton. Specific chloride ore samples have shown: 1,000 ounces of silver per ton; 35 percent lead content; Small amounts of gold ($2–$5 per ton).
The site is split between two main operations:
- South Shaft: Features a 50-horsepower hoist, a six-drill air compressor, and a top-tier machine shop.
- North Shaft: Equipped with a 50-horsepower single drum hoist, powered by air from the south station.

Colorado Consolidated Mining Company, 1916

In May 1916, the Beck Tunnel Consolidated Mining company was consolidated with the Colorado Mining company to create the Colorado Consolidated Mning company.

May 2, 1916
At a special meeting held on March 28, 1916, the board of directors of the Beck Tunnel Consolidated Mining company voted to approve the consolidation of the company with the Colorado Mining company, and to organize a new corporation, for the purpose of purchasing and taking over all assets, properties and interests of the Beck Tunnel Consolidated Mining company, and the Colorado Mining company. A special meeting of stockholders was held on May 2, 1916 to ratify the decision and recommendation of the board of directors. (Provo Daily Herald, May 1, 1916)

January 15, 1917
"Mr. Knight is known as one of the most successful mine operators in the west, and has made great dividend-payers of three of the greatest mines in the country, namely, the Beck Tunnel Consolidated, the Colorado and the Iron Blossom." (Salt Lake Tribune, January 15, 1917, upon Knight's visit to the Chloride mining district in Arizona)

November 24, 1928
An assessment against the stock of the Beck Tunnel Consolidated Mining company, along with the stock of the Colorado Mining company, the Old American Mining company, and the Salvador Mining company, with the assessment to the treasurer of the Colorado Consolidated Mining company. The stock of any unpaid assessment would be sold at public auction to pay the said assessment and any costs of advertising and expenses of the sale. (Goodwin's Weekly, November 24, 1928)

August 31, 1933
"A number of leasers were busy at the Uncle Sam mine. The best lease was that of Joseph Gagon, this block of ground was on the Uncle Sam-Beck Tunnel line, and was a high grade lead-silver product. The royalities from this lease were divided between the two companies." (Eureka Reporter, August 31, 1933)

(During the Great Depression, many large mining companies in Eureka could not afford to operate at full capacity due to low metal prices. To keep the mines open and the town employed, they used a leasing system. The leasers were independent miners either in small groups or as individuals would "lease" a specific "block" of ground within a larger mine. The leasers paid for their own supplies and labor, then gave a percentage of their earningsas royalties to the company that owned the mining claim. If a leaser worked a block of mineral ground that sat on the boundary line between two properties (like the Uncle Sam and Beck Tunnel companies, above, the royalties were split between both companies.)
