“There is certainly scope for a work on diamond drilling, and Mr. Denny deserves grateful recognition for supplying a decided want. We strongly recommend every board of directors to carefully peruse the pages treating of the applicability of diamond drilling to auriferous deposits, and, under certain conditions, its advantages over shaft sinking for systematic prospecting, both from the surface and underground. The author has given us a valuable volume of eminently practical data that should be in the possession of those interested in mining.”—Mining Journal.
“Mr. Denny’s handbook is the first English work to give a detailed account of the use of modern diamond core-drills in searching for mineral deposits. The work contains much information of a practical character, including particulars of the cost of apparatus and of working.”—Nature.
