Bingham Canyon Mining and the Mascotte Tunnel Legacy
At the turn of the 20th century, the rugged landscape of Bingham Canyon, southwest of Salt Lake City, Utah, became a focal point for industrial ambition and corporate maneuvering. The region's rich mineral deposits attracted high-profile investors, most notably F Augustus Heinze, whose involvement in the area would be marked by strategic acquisitions and intense legal battles.
Heinze sought to establish a dominant presence in Utah by purchasing controlling interests in the Bingham Consolidated Mining and Smelting Company and the Ohio Copper Company. However, his tenure was fraught with difficulty; as he fought numerous legal charges in court, his mining operations struggled to secure necessary funding. Ultimately, Heinze's presence in Utah became more of a hindrance than a help to the companies he controlled.

The Geography of Bingham Canyon
The operational environment of the era was defined by the extreme topography of the region. The mining operations and mills for all companies in the area were squeezed into the narrow confines of Bingham Canyon. This included the Ohio Copper Company's Winnamuck mill, which had a small capacity of 150 tons per day.
The canyon was famously restrictive; local lore suggested it was so narrow that a dog would have to wag its tail up and down rather than side to side to avoid hitting the canyon walls.
The Strategic Importance of the Mascotte Tunnel
To overcome the geographical limitations of the canyon and gain a competitive edge, the Ohio Copper Company planned to transport ore to a new mill in the township of Lark, located outside the canyon. This proposed mill was designed with a significantly larger capacity of 3,000 tons per day.
The only viable way to transport the ore to this location was through a tunnel. In 1907, work began on expanding the existing Dalton & Lark tunnel. This three-mile passage was renamed the Mascotte Tunnel in honor of an early director of the Dalton & Lark company.
Heinze utilized a strategic corporate maneuver to secure the tunnel. While the tunnel was still unfinished and owned by the struggling Bingham Consolidated, Heinze—a major stockholder—arranged for the asset to be sold to the Bingham Central Railway Company, a firm he owned entirely, for $150,000. This gave Heinze sole ownership of the only route connecting the Ohio Copper Company's mines to its mill.

Completion and Engineering
The Mascotte Tunnel was completed in March 1909. General Manager Colin McIntosh praised the surveying work as some of the most difficult in the state, noting that the project was completed with perfect accuracy. Upon the tunnel's completion, Heinze visited Salt Lake City for the first time since 1906, where he was warmly received by miners who had previously worked for him in Montana. The tunnel exit is located at coordinates 40°31'37" N, 112°05'52" W.
Corporate Conflict and Financial Decline
By 1909, shareholders of the Ohio Copper Company grew anxious over Heinze's control of the Mascotte Tunnel. Because the tunnel was the company's only "lifeline," directors feared that Heinze could deny access to the mill, forcing the company to use expensive and inefficient alternative methods. This leverage gave Heinze a commanding position over the company's operations.
This strategic bottleneck led to a failed acquisition attempt by Amalgamated Copper. Representatives John D. Ryan and Thomas F. Cole offered to buy the Ohio Copper Company, but only on the condition that the Mascotte Tunnel be included in the deal. Heinze refused the offer.
By December 1910, dissatisfaction peaked. Large shareholders argued that management was failing and earnings were insufficient to satisfy creditors. Meanwhile, Heinze's Bingham Central Railway Company charged the Ohio Copper Company 15 cents per ton of ore transported, netting Heinze approximately $200–$300 per day.
The Fall of Heinze and the Legacy of Ohio Copper
The reputation of Heinze's business practices was severely criticized in the 1911 Steven's Copper Handbook, which described his operation of the United Copper Company as a "blind pool" and characterized his financial dealings as "stock jobbery." The handbook noted that Dutch investors, who held about one-third of the common stock, were struggling to obtain clear information about the company's affairs.
The collapse began in February 1913 when the United Copper Company entered receivership to unwind its assets. In mid-1914, control of the Ohio Copper Company officially passed from Heinze to the company president, William O. Allison, during a contentious shareholders meeting. Heinze attributed his failure to meet payment obligations to his ongoing legal expenses.
Following this transition, the Bingham Central Railway Company and the Mascotte Tunnel were merged into the company, which was renamed the Ohio Copper Mining Company of Utah. This entity operated until 1951, and its former properties are now integrated into the massive Bingham Canyon Mine.

Frequently Asked Questions
Why was the Mascotte Tunnel so important to the Ohio Copper Company?
The tunnel provided the only efficient route to transport ore from the mines in the narrow Bingham Canyon to the high-capacity mill located in the township of Lark.
How did F Augustus Heinze gain control over the mining operations?
Heinze purchased controlling interests in the Bingham Consolidated Mining and Smelting Company and the Ohio Copper Company, and strategically bought the Mascotte Tunnel through his own company, the Bingham Central Railway Company.
What happened to the Ohio Copper Company after Heinze left?
The company merged with the Bingham Central Railway Company to become the Ohio Copper Mining Company of Utah, which continued operations until 1951.
Where is the Mascotte Tunnel located?
The exit of the tunnel is located at the geographic coordinates 40°31'37" N, 112°05'52" W.
What was the result of the offer from Amalgamated Copper?
Amalgamated Copper offered to purchase the Ohio Copper Company, but the deal failed because Heinze refused to include the Mascotte Tunnel as part of the sale.
