Goat Mountain alkalic plug intrudes greenstone belt rocks in the Rattlesnake Hills. |
A previously unrecognized gold district was discovered in 1981 based on favorable geology - a greenstone belt intruded and brecciated by a swarm of alkalic intrusives. The project was funded by Wyoming Geological Survey (WGS) general funds and University of Wyoming MMRRI grants to the author. Some anomalies were later drilled by private industry resulting in significant gold intercepts. A final report was presented to MMRRI in 1982 and formal publication to WGS in 1996.
