Excerpt from The Mining Magazine, Vol. 8: January to June, 1913 The Kyshtim continues to grow. From the latest figures it is apparent that the Ameri kansky orebody, east of the Karabash smelter, is an important asset. Seven boreholes have tested this orebody, so that Mr. R. Gilman Brown is able to estimate that tons of 314% copper ore have been proved. The total reserve in the four mines is now esti mated at tons, with more tons regarded as probable. For 1913 the out put is expected to be to tons of ore, yielding 7600 to 8000 tons of copper. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
