This paper discusses a Personal Computer (PC) software package that reduces the time required to evaluate a mineral reserve. It provides for: •Entry of borehole data onto PC diskettes and the creation of a borehole database; •Capture of map data using an attached X-Y digitizer; •Calculation of uniform square grids for thickness, mineral qualities, overburden ratio, etc., •Compilation of multiple such grids into a digital model, and iterative evaluation of the model with the user applying constraints and cut-off values; and • Graphic display of grid cells (blocks) showing which cells failed, and on which constraint(s), and a complete reserve report showing tonnages, averages, histograms, and quality arrays.

WHEN the atomic age broke suddenly upon the world in 1945 with all its terrible implications, predictions concerning the future of atomic energy were as numerous as columnists and often inflated. Today, some seven years since the explosion and probably ten since the Government took over development of nuclear energy, the impact on our way of living has been largely political (except of course for the thousands of people who have become employed in the AEC). Considering the world situation, weapons have come first naturally. But credible progress in the plow-share uses of nuclear energy-medicine, agriculture, power-can also be noted.

This paper reviews various methods for measuring the product output from oil shale processes. These include comparison with Fischer assay product yields, measuring conversion of feed oil shale organic carbon to volatile products, and measuring output of combustion energy in the form of product liquid and gas.

Meeting of Nov. 20, 1914.-Charles F. Rand was unanimously elected as the representative of the Institute on the John Fritz Medal Board of Award. E. Gybbon. Spilsbury was unanimously elected to succeed himself in January, 1915, on the Library Board of the United Engineering Society. . The President appointed Messrs. Walter Douglas, Charles E. Mills, and L. D. Ricketts as delegates to the seventeenth National Convention of the American Mining Congress, Phoenix, Ariz., Dec. 7 to 11, 1914. It was voted that the sum of $857.61, or so much of it as may be necessary, be advanced to the Land Fund from the general funds of the Institute, in anticipation of the collection of unpaid installments of subscriptions to the Land Fund; and that the Treasurer be instructed to pay to Andrew Carnegie at the present. time the sum of $2,500 on account of the Land Fund indebtedness.

Five factors are required for the formation of uranium deposits: a source, transporting medium, host, trap, and preservation. Locating and evaluating uranium deposits requires ail integration of methods and techniques to determine if the above factors are present. A typical exploration program consists of selection of a favorable area, field reconnaissance, land acquisition, and target definition and evaluation. Target definition and evaluation utilizes a combination of geologic mapping, geochemical surveying, geophysical surveying, and drilling and logging. Each overlaps the others to some degree.

The Mineral Engineering Department of The Pennsylvania State University has developed a suite of computer models for anthracite open pit mining (Fig. 1)1 Individual sub-systems have been developed to (a) interpolate geologic field data to obtain coal tonnages, waste volumes, and strip ratios; (b) simulate equipment performance on selected pit profiles to generate data required to choose coal and waste removal equipment; and (c) evaluate selected cost factors to determine either a rate of return for a specified selling price or vice-versa. This paper describes the application of two of these subsystems, namely, the Reserves Model (GEOL) and the Open Pit Materials Handling Simulator (OPMHS), and how these may be applied for the selection of equipment for a prime anthracite mining site.2
