The Cameron Mine was opened by the Colorado Coal and Iron Company in 1882. The Mine itself was named after a manager of the CC&I company who died in 1881, James Cameron. The Cameron mine was located south of Walsenburg and located along a branch of the C&S Railroad. In 1892 the mine was integrated into the Colorado Fuel and Iron company. By 1907 a Company town with store and housing was established and called Farr. The Cameron Mine operated until 1946 when it was shut down.

Crested Butte Mine (coal)
The Crested Butte mine was located to the south west of The Crested Butte Town and opened in 1895. The coal produced at the Crested Butte Mine was light bituminous coking coal, which was used at the one hundred and fifty coking ovens left over from the Jokerville mine after its closure. The Crested Butte Mine operated until 1952.

Cuatro Mine (coal)
The Cuatro Mine was located thirty four miles west of Trinidad, in Las Animas County. The Mine opened in November of 1902. The Cuatro shared both access to the company store of the Tercio mine as well as the school. The Mine suffered intermittent operations due to strike in 1903 through 1904. On April 22,1906 a mine explosion killed 19 miners and the mine was closed by 1907.

Emerald (coal)
Nearly equidistant from Rockvale, Florence and Brookside are the relatively small workings of the Emerald mine. The Emerald operations were taken over by CF&I in 1919 who pulled a relatively small amount of coal from it until its closure in 1925. The map below from the Steelworks Center of the West archives also shows portions of the Fremont and Magnet mines, as well as the Willie mine, which was not held by CF&I.

Floresta Mine (coal)
The Floresta mine also known as Ruby opened in 1893 in Gunnison County. It was located eleven miles west of Crested Butte. The Floresta mine was accessed by narrow gauge rail operated by the Denver and Rio Grand Rail road. The coal mined at the Floresta Coal Mine was a type of anthracite. Anthracite coal has the highest percentage of carbon of all coal types and was the most desired for heat in domestic settings due to its clean burning nature and low smoke production. The Floresta Mine operated on average only half of the year due to location and mountain snow. Floresta was closed in 1920.

Fremont/Bear Gulch (coal)
CF&I began operations in the Bear Gulch shaft (as it was then known to locals) in 1896. A fire destroyed most of the surface works in 1905, but they were rebuilt and coal production continued until it was abandoned in 1927. The official reason for closing the mine was poor quality coal, but the map from the Steelworks archives contains notes about water flow intruding from other nearby mines that were sabotaged during labor disputes around the same time.

Kebler Nos. 1&2
Kebler No. 1- or the Big Four- and Kebler No. 2- also known as Tioga which means "where it forks" probably refers to the road that forks here, where one can continue west to Gardner or south to the site of Alamo. Originally operated by the Big Four Coal Company starting in 1907. In 1910 the mine was leased or sold to Minnequa Fuel Company. In 1919 CF&I bought the mine. Big Four was now known as Kebler No. 2, and soon closed. A new slope was driven and called Tioga, or confusingly, Kebler No. 2. Another new opening was called Kebler No. 1. Operations ended in 1953. Production: 5,000,000 + tons.

Lester (coal)

Photos from the Steelworks archives make it clear that the limestone quarry at Lime was in full production by 1902, with many company built houses, a school, a store and CF&I offices. It was still in production in the 1960s.

An excavated mine shaft adjacent to the former train station site at Cima in 1906, the mine was eventually named after CF&I executive and mine owner Thomas Morley. Operations ended in 1956.

Nonac (coal)
Nonac (Canon spelled backwards), also called Rockvale No.5 is located just south of Canon City on land originally leased by Canon City Coal Company. CF&I obtained the lease in 1903 and it operated intermittently until 1952 with a total of just over 2,000,000 tons of coal produced.

Orient (iron)
Located near the western slope of the northern extant of the Sangre de Cristo range, thus making it the eastern or orient side of the San Luis Valley, is the Orient Iron Mine. It was active from 1880 through 1932, and, having produced about two million tons of limonite, an iron(III) bearing ore, it was the largest producer of iron ore in Colorado. At its peak, the town of Orient had a population of more than 400, and amenities such as a boarding house for 300, a saloon, a milling company, a library, a barber shop, a school, 2 restaurants, and other small businesses including a supplier of work clothing. Today the mine is the summer home of 250,000 migratory bats and five or six populations of hibernating bats.

Rockvale (coal)
Rockvale 1 opened in 1879 by the Canon City Coal Company. It is located 4 miles west of Florence and 10 miles southeast of Canon City. The mine was leased by CF&I in 1896. A 1927 CF&I sales manual calls it the largest operation in Canon City. It produced 4,516,907 tons of coal before it closed in 1928 when, during a labor dispute, workers shut down the pumps that removed the ground water that would seep into the mine. The flood damage was so severe that CF&I chose to abandon the mine instead of attempting to dry it out.

Rockvale 2 (aka Coal Creek 1) was begun in 1872 by the Central Colorado Improvement Company. In 1900 CCI Company merged with the Colorado Coal and Steelworks Company and the Southern Colorado Coal and Town Company to forum the Colorado Coal and Iron Company. In 1886 this company bought the nearby Caldwell (aka Canfield) mine. Both of these mines were in operation when CC&I merged with the Colorado Fuel Company to forum Colorado Fuel and Iron Company. In 1912 CF&I started a new shaft in the vicinity to be called Rockvale 3 (aka Coal Creek 2, aka Nushaft). Although the three mines were interconnected, after 1913 all the coal was removed at the modern, electrified Nushaft entrance. The mine produced 3,686,226 tons of coal from 1892 (CF&I founding) until closure in 1931.

Rouse (coal)
Originally located six miles south of Walsenburg, Rouse was the No. 4 mine of the CF&I Company. It opened in 1888 as the biggest coal mine in the state, and in 1889 was the leading producer in Huerfano County, averaging 70 rail cars a day. In 1897 water entered the Rouse mine, and plagued operations to no end. By the spring of 1899 it had become obvious that all the pumps in the world could not make Rouse a profitable operation, which is amazing as it produced 3,461,932 tons in those 11 years, all of it mined by hand and moved by mules. Pumps were removing some 1,500 gallons of water per minute, and it was not enough. The company made the decision to close the mine and move the camp and equipment to its Santa Clara mines several miles south of Rouse. Old Rouse was abandoned and a New Rouse arose in 1899 and remained in operation until 1920. New Rouse Production: 2,095,239 tons.
