Abstract
The objectives of this study were (1) to determine potential alternative mining systems for some of the large Tertiary channel gold-bearing gravel deposits, and (2) to identify areas of technology where further investigation would be merited because of its potential inclusion in a mining system for such deposits. The study involved the development of a mineralized block inventory, an economic block inventory, determination of optimum ultimate mining limits, and a preliminary economic mining system evaluation. Computer programs were developed and utilized for each of the study phases stated. The analysis showed that underground mining of the six-mile deposit was uneconomical, but that potential for an economic mining operation existed when the gravel resources of the channel were considered together with the gold.
