Principles of Mining: Valuation, Organization and Administration

The author sets out practical guidance for assessing and managing metal lode mines, presenting methods for sampling, assays, and calculating recoverable value alongside geological considerations that affect prospective extension. The book covers planning and executing underground development—tunnels, shafts, levels, stoping, and support—plus selection and maintenance of mechanical equipment for hauling, drainage, and drilling. Economic chapters examine output limits, cost accounting, amortization, labor organization and efficiency, and administrative reporting. Final sections address investment risk and the training, duties, and professional responsibilities of mining engineers, emphasizing the interplay of technical decisions and management in securing profitable operation.
