Excerpt from Mine Sampling and Valuing: A Discussion of the Methods Used in Sampling and Valuing Ore Deposits, With Especial Reference to the Work of Valuation by the Independent Engineer

The discussion contained therein was a most valuable one at the time, but on the whole it lacks that continuity of thought which the subject deserves.

We owe, too, a great deal to H. C. Hoover, who, in his book 'principles of Mining,' has contributed a valuable discussion on mine valuation. It is a source of wonder to me that this matter has not been seriously taken in hand heretofore, because it must be remem bered that the whole success of mining operations is often absolutely dependent on accurate mine sampling. I therefore trust that the following pages may serve as a guide to the young engineer and may not be without value to the more experienced and older men.

Excerpt from Mine Sampling and Valuing: A Discussion of the Methods Used in Sampling and Valuing Ore Deposits, With Especial Reference to the Work of Valuation by the Independent Engineer

In the past a great deal has been written on the subject of mine sampling and valuation, but for the most part the literature is fragmentary, and I believe that scarcely anywhere is there any reference made to its elementary side. Somehow or other, engineers pick up a knowledge of this part of the business, although I do not think that the methods of mine sampling are taught in schools of mines, nor do the text-books on mining deal with it in detail.

A few years ago T. A. Rickard, who at that time was editor of the Engineering and Mining Journal of New York, wrote a series of articles that were followed by contributions from various engineers. These articles and the ensuing discussion were eventually published in book form with the title of 'The Sampling and Estimation of Ore in a Mine.' Aside from this, no attempt at a comprehensive work on the subject exists, and for that reason Mr. Rickard's book has since then served as a sort of text-book to the younger engineers desiring information on this phase of mining engineering. The discussion contained therein was a most valuable one at the time, but on the whole it lacks that continuity of thought which the subject deserves.

We owe, too, a great deal to H. C. Hoover, who, in his book 'Principles of Mining,' has contributed a valuable discussion on mine valuation. It is a source of wonder to me that this matter has not been seriously taken in hand heretofore, because it must be remembered that the whole success of mining operations is often absolutely dependent on accurate mine sampling. I therefore trust that the following pages may serve as a guide to the young engineer and may not be without value to the more experienced and older men.

I am indebted to Messrs. Frank H. Probert and Lloyd T. Buell for information regarding churn drilling, as also to E. N.Skinner; to H.S. Munroe for his views on the gravimetric method of calculating averages and to others who have been good enough to offer suggestions of various kinds.
