Al Kushaymiyah as a target for a Colorado-type molybdenite deposit

Abstract

Department of State, undertook a joint and cooperative effort to map and evaluate the mineral potential of central and western Saudi Arabia. The results of this program are being released in USGS open files in the United States and are also available in the Library of the Ministry of Petroleum and Mineral Resources. Also on open file in that office is a large amount of material, in the form of unpublished manuscripts, maps, field notes, drill logs, annotated aerial photographs, etc., that has resulted from other previous geologic work by Saudi Arabian government agencies. The Government of Saudi Arabia makes this information available to interested persons, and lias set up a liberal mining code which is included in "Mineral Resources of Saudi Arabia, a Guide for Investment and Development," published in 1965 as Bulletin 1 of the Ministry of

The mineral resource potential of the Thaniyah and Al Ufayriyah quadrangles, sheets 20/42 C and 20/42 A, Kingdom of Saudi Arabia

“…An earlier wadi-sediment survey detected anomalous amounts of tin and molybdenum in rocks from part of this unit (Theobald, 1970).…”

“…One of these samples (170126) is within a 5-minute quadrangle area that was identified by Theobald (1970) as anomalous in tin and moybdenum, based on results of a regional wadi-sediment geochemistry survey.…”

“…Previous mineral exploration Whitlow(iUU,l?7/) and Theobald (1970) conducted reconnaissance wadi-sediment surveys in areas that included the Thaniyah and Al Ufayriyah quadrangles.…”

“…However, studies of other major tungsten anomalies in the Arabian Shield, for example, the quartz-vein stockwork systems at Al Kushaymiya (Whitlow, 1966;Theobald, 1971) and Baid al Jimalah (Cole and others, 1981), showed wolframite ((Fe, Mn) W04) as the principal tungsten mineral.…”

“…longitude be given a high priority. Theobald (1970) amassed and summarized values of tungsten, molybdenum, and tin determined on heavy mineral concentrates from wadi sediments collected from throughout much of the Arabian shield. In this report, Theobald postulated that the Kushaymiyah area, the general area Whitlow had previously recommended for further exploration, had close similarities with well-known areas of ore deposits in Colorado and New Mexico, U.S.A., and suggested that a study of the area should be undertaken in search of a stockwork molybdenite deposit.…”
