Abstract

Geochemical exploration studies were undertaken in the Cripple Creek district to test the possibility that large low-grade gold deposits might be found. Surface rock samples taken throughout the district indicate that the volcanic rocks between the productive veins contain an average of about 0.6 ppm (part per million) gold. In an area above 3,800 feet long and 500 feet wide near the Cresson mine in the south-central part of the district, scattered surface samples show that the rocks contain an average of 2.5 ppm gold, equivalent to $2.50 per ton. Inasmuch as veins that contain more than 2.5 ppm may also exist in the area, systematic sampling by trenching and drilling is warranted.
