The Tintic Historical Society is very grateful to Lowell Didas from the Tintic Ophir and Wester Model Train Club for Donating a model of the Bullion Beck Headframe. The Model Train Show is at the Orem Mall until Saturday March 21st. The Bullion Beck Headframe is at the West entrance of Eureka. It is over 70 feet tall, and is one of Eureka's "Big Four", with connecting underground working with the Gemini and Eureka Hill Mines. This style of Headframe was capable of lifting mine carts from depths of up to 3000 feet. Underground mining enabled Eureka to be an important railway destination.

The Mammoth Mill in Juab County Utah was first used in 1882. The mill had a battery of 27 stamps and used a wet amalgamation process. In the early days 50% of the gold and silver values contained in the ore and all the copper was entirely lost. In 1883 a furnace plant was constructed to produce copper matte. This method proved successful with losses of only one half of one percent. By 1898 the mill had a 60 stamps and 13 furnaces. Ores of this time averaged 0.725 oz per ton gold, 25.43 oz per ton Silver, and 10% copper. In 1898 the Mammoth mill reduced 38,107 tons of ore and turned out 3578 tons of concentrates, besides many bars of bullion. With the arrival of the railroad it became more profitable to direct ship ore to smelters in salt lake valley. By 1908 the mammoth mill was dismantled and vacated.

The Gold Chain Dump in Mammoth Utah is one of the best places in the Tintic District to find Copper and Zinc Carbonate minerals. Once cut and polished the crystal shapes and mineralized cracks become much more clear.

Thanks to our dedicated volunteers and donors we were able to install a new corrugate roof on the Rockwell Cabin. The Cabin came from The Porter Rockwell Ranch on the East side of Cherry Creek in the West Tintic Mountains. It is made of native pinyon pine logs and mud gathered from the ranch. The roof is thatched from cedar bark and experience a leak earlier this year.
