The Birdie Mine Tungsten Deposit Butte Mining District, Silverbow County, Montana, Bernard A. Fahm
The Birdie Mine Tungsten Deposit Butte Mining District, Silverbow County, Montana, Bernard A. Fahm
Bachelors Theses and Reports, 1928 - 1970
The importance of tungsten has encouraged the search for minerals of this metal, and consequently new deposits have been discovered, and known deposits have been re-examined. Western Montana has rather widespread deposits if low-grade types are also considered. Many deposits were known long ago, but abandoned because the use of tungsten was still in its beginning stage and therefore little attention was given to this type of mineral.

Fauna Of The Pilgrim Formation Of The South Boulder Creek Area In Southwestern Montana, John T. Eastlick
Bachelors Theses and Reports, 1928 - 1970
This paper, a study of the fauna of the Pilgrim formation at South Boulder Creek in southwestern Montana, represents a laboratory study of the fossil specimens collected by Dr. Alvin Hanson during the summer of 1949. The scope of investigation includes identification and classification of the faunas, their stratigraphic relationship and zonal subdivisions.
Coal In Montana, Clifford A. Barkell
Coal In Montana, Clifford A. Barkell
Bachelors Theses and Reports, 1928 - 1970
Coal was first mined in Montana in the year 1880. For the last thirty years the mining of coal in this state has been very important-with few people realizing its value. In the mineral industry, the value of the annual production of coal is exceeded by none of the non-metallics, and only by gold, silver, and copper in the metallics. At the present time the coal production of Montana is valued at about 41000,000.00 annually.
The General Geology Of The Cardwell Mining District, Clyde Congdon
The General Geology Of The Cardwell Mining District, Clyde Congdon
Bachelors Theses and Reports, 1928 - 1970
The Cardwell Mining District is part of the greater Whitehall Mining District. The district is situated about four miles to the east and northeast of Whitehall in the southern end of the Bull Mountains which are near the Continental Divide. The first reported production was in 1896 after the discovery of the Mayflower Mine. Mining has been carried on intermittently and on a small scale since that time.
Leaching Copper Minerals In The Butte District, Kenneth C. Bellows
Leaching Copper Minerals In The Butte District, Kenneth C. Bellows
Bachelors Theses and Reports, 1928 - 1970
The history of mining in Butte is woven about three of our principal metals. The gold placers first attracted the attention of miners in 1863, and reached their peak production in 1867. Silver was the second metal mined, and this operation required the erection of large mills with a consequent increase in mining activity that made the district a prominent producer. Although the presence of copper in the silver ore had been known, the credit for the first development of the copper veins is due Senator W. A. Clark. The original Colusa, Mining Chief, and Gambetta claims were developed to …
Joint Planes In The Rhyolites Of The Butte District, Montana, John B. Hopkins
Joint Planes In The Rhyolites Of The Butte District, Montana, John B. Hopkins
Bachelors Theses and Reports, 1928 - 1970
The problem herein discussed deals with the pointing planes found in the area of rhyolite located in the northwestern portion of the Butte District. The question to be determined was whether or not the pointing planes in the rhyolites could be classified with the Butte Ore fissure systems.
