Lode-Star Gold, Inc., in advance of their proposed mining operations, submited a Physical Separation Facility application with the State of Nevada for their Goldfield Bonanza Project located in Esmeralda County, Nevada. The mine, located in the historic high-grade gold-bearing district of Goldfield, Nevada, produced just under 4 million ounces of gold from 1904 to 1918. As part of the permitting application, Tierra Group prepared the design of a waste rock storage option within the underground workings and abandoned shafts at the site. Tierra Group also aided in preparing figures and conceptual drawings required in the permitting process.
