Mining Magnate

John Dern first came to Utah as president of the Mercur Gold Mining and Milling company in December 1890. He was a resident of Fremont, the county seat of Dodge County, where he was the County Treasurer. In June 1894, Dern and his Eastern associates purchased full control of the Mercur company, from its previous majority stockholder, at which time John Dern became president and general manager of the Mercur mine.

At its first annual meeting in mid January 1891, John Dern was elected as president of the newly formed Mercur Gold Mining and Milling company. He was shown as a resident of Fremont, Nebraska.

John Dern remained with the Mercur Gold company in July 1900 when it was merged with the adjacent Mercur Mines company which owned the Golden Gate mill. The new company was known as the Consolidated Mercur Gold Mining company, with Dern as vice president. In 1901 he became president of the Consolidated Mercur company. His son, George H. Dern was General Manager of the company. The Consolidated Mercur company shut down its operations in March 1913 due to the deteriorating quality of the ore being mined, making the whole operation unprofitable.

In addition to the Mercur company, John Dern's mining interests included investments on several Tintic mines, along with being president and general manager of the Uncle Sam mine, the May Day mine, and the Lower Mammoth mine.

In June 1901 Dern and his Eastern and Salt Lake City associates were majority stockholders of the Uncle Sam Mining company in the Tintic district when he and others took ownership from Jesse Knight. He remained as the company's president until his death in 1922.

Immigrant

John Dern and Elizabeth Dern (1852-1920) had immigrated to the United States when they were children. According to the 1910 U.S. Census, John emigrated in 1865, and Elizabeth emigrated in 1869. John was shown as a naturalized citizen.

Both Elizabeth and John came from prominent families. They married in 1870, and by the 1880s John was operating a grain elevator and managing a lumber business in Fremont, Nebraska. He became a Nebraska state senator and served as Nebraska state treasurer. In 1890 he became involved in a business enterprise in an old abandoned silver mine in Lewiston, Utah. John and his business partners utilized a special cyanide solution to leach gold out of the ore at a gold ledge in the mine. After 1892, John became president of the Mercur Gold Mining and Milling Company, and moved his family to Salt Lake City, including the five children.

1897
John Dern and his family moved into their home on Brigham Street (711 East South Temple street) in 1897. The Dern mansion became the Utah governor's home during the years 1925-1932 when George H. Dern was governor of Utah.

In December 1922, the John Dern estate paid the Utah state inheritance tax of $39,575.02, based on the estate's value of $839,846.40. John Dern had been one of the wealthiest men in Utah, with almost all of his wealth coming from his mining interests that began in 1891 at Mercur.

From the Salt Lake Telegram, October 1, 1910

John Dern, who has been elected president of the American mining congress at the convention just held at Los Angeles, is one of the most active mining men in Utah. He came here from Nebraska more than fifteen years ago, and has been successfully engaged in mining since he made this city his home.

His first adventure in a mining way was becoming interested in the old Mercur mine with some of his business associates from Nebraska. They were successful with Mr. Dern at the head of the company. Later they took over the holdings of Captain Delamar in that camp and formed the Consolidated Mercur Mines company, which has paid over $3,000,000 in dividends and is still mining low grade ores in that section of the state. From Mercur he extended his investments into almost every camp in the west, and is the head of Uncle Sam Consolidated, Lower Mammoth and May Day Mining companies in Tintic.

Mr. Dern has taken an active part in the American mining congress since its inception, and was one of its charter members. He has always occupied one of the executive offices, and has several times refused to allow his name to go before the convention as its president. Upon his return from Europe recently he decided that since the congress had been successful in getting the establishment of the bureau of mines by the government, there was more work to be done which would better mining conditions. He went to the convention at Los Angeles, and has taken active part in its deliberations.
