Excerpt from Mining Costs of the World: A Compilation of Cost and Other Important Data on the World's Principal Mines The writers have long believed that there is need for a book of this char acter, embodying in condensed form costs and other important operating data on the metal mines of the world. This book, which covers about three hundred and twenty-five metal mines, is not a text but a compilation of results actually Obtained at the various properties shown therein. It should be of material assistance to the engineer, manager, superintendent, operator and student. We realize that nearly every mining man has his own notebook, but rarely are these data complete and conveniently arranged in pocket book form. The examining engineer and Operator frequently find it difficult to Obtain reliable data in camps they are visiting. This book gives the desired information, embody ing as it does most of the principal camps of the world: It is evident that no just comparison can be drawn between any two mines, as no two are Operated under identical conditions. In a great major ity of cases we have given Operating results for several years. There is a constant aim to increase production with decreasing costs, but as this is not a rapid nor radical movement figures from year to year undergo very slight changes. It is our intention, however, from time to time to augment the book, adding new mines to the list, later data and more complete information.
