Subject: This report presents an investigation of a reportedly large low-grade ore body in the vicinity of Cameron, Arizona.

From introduction: Twenty-nine samples of sedimentary rocks of Triassic age from the Sun Valley uranium mine in northern Arizona were analyzed spectrographically, and 11 of these samples contained 0.005 to 0.1 percent of the rare metallic element, rhenium.

Abstract: A study, consisting of field and laboratory work, was undertaken in an endeavor to establish possible structural mineralization controls associated with the copper-uranium occurrences in the Willaha area, Coconino County, Arizona. Uranium mineralization, apparent at present, is localized along small fissures and vugs and in certain beds and lenses of the middle member of the Kaibab formation(Permian). It is associated with copper and iron oxide staining. Though no definite ore controls were disclosed by this study, at least a limited program of shallow drilling is warranted on the property. This sub-surface exploration should determine possible extensions of known mineralized areas, explore surface radiometric anomalies, and provide data for the determination of possible guides to ore. Deeper exploration may encounter mineralization in other horizons of the Kaibab limestone.

Introduction: A radiometric airborne reconnaissance of the Cameron, Arizona, district was conducted in the late fall of 1952 and early winter of 1953. Flying was carried out under the direction of the Salt Lake Exploration Branch of the Atomic Energy Commission, Division of Raw Materials. Airborne equipment and ground personnel were provided through the Technical Services Branch of the Grand Junction Exploration Division.

Photograph of the rail side of a railway depot located at the terminus of the branch line at the south rim of the Grand Canyon. It is a wooden structure with log cabin-style architecture and "Grand Canyon" written in the gable end above the entryway. Several unidentified people are standing in front of the building and a truck is parked on the right side of the image.
