Resumo |
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. |
