Exploratory drilling practices and costs at western uranium deposits / by Donald E. Redmon.
Exploration of hidden mineral deposits becomes increasingly important as known ore reserves are depleted. The primary objective in any exploratory program is to obtain enough reliable information to evaluate accurately the potential of the mineral deposit. Constant improvement in equipment and techn...

| 520 | |a Exploration of hidden mineral deposits becomes increasingly important as known ore reserves are depleted. The primary objective in any exploratory program is to obtain enough reliable information to evaluate accurately the potential of the mineral deposit. Constant improvement in equipment and technique has established drilling as one of the most valuable methods of exploration. This paper presents the results of studies of several drilling methods currently used in the search for uranium deposits in sedimentary formations from surface drill sites. Also presented is a description of drilling with wire-line equipment from an underground location in metamorphic rocks. The studies were conducted in the Colorado Plateau area and in northwestern New Mexico and Wyoming. Statements of a general nature pertain to conditions or situations existent in those areas. | ||
