  • drilling for gold in wyomingThe Rattlesnake Hills gold prospect is located in Natrona County, Wyoming, approximately 70 kilometers west of the city of Casper and consists of 3300 acres. Evolving Gold acquired a 100% undivided interest in the prospect, as a result of an Option Agreement between Evolving and Golden Predator US Mines Inc. and Bald Mountain Mining Company. Evolving has added to the prospect thorugh a staking program.

    The Rocky Mountain alkaline gold province is host to a series of world class gold deposits including Zortman-Landusky, Montana, Bald Mountain, South Dakota, Ortiz, New Mexico and the great Cripple Creek deposit, Colorado. By acquiring the Rattlesnake Hills property, Evolving now has the opportunity to explore for yet another of these prolific gold deposits.

    The geological setting and style of gold mineralization at Rattlesnake is very similar to the world-class gold deposits at Cripple Creek. Low-sulphide, disseminated gold is hosted primarily by diatreme breccias which halo a complex of alkali intrusive stocks and plugs and, like its regional counterparts, is associated with widespread potassic alteration.

    Limited drilling and surface exploration at Rattlesnake was carried out by American Copper and Nickel Company (ACNC) between 1983 and 1987, and subsequently by Newmont Exploration Ltd. between 1993 and 1995. ACNC completed 32 reverse circulation shallow drill holes targeting banded iron formations which occur peripheral to the much younger breccias bodies. Subsequent drilling by Newmont consisted of 14 holes (including two core holes) targeted the diatreme breccias which border one of the alkali stocks, called the North Stock. Gold grades reported by Newmont ranged up to 148 meters averaging 1.44 grams per metric ton (gpt), with higher grade intervals over narrower widths. The mineralization is open to depth, and only a small proportion of the hydrothermal system has been tested.

    Evolving believes that the Rattlesnake prospect has been shallowly eroded, and that the limited previous drilling has identified the upper part of a gold-mineralized system preserved at depth. Narrow, higher-grade intersections (up to 10 gpt gold) in the deeper parts of historic drill holes, along with textures and mineralogy of the veins, support this model.

    Drilling began at Rattlesnake in the third week of June 2008.
