Abstract

Areas with potential for metallic mineral deposits in the Wadi al Jarir and Al Jurdhawiyah quadrangles, northeastern Arabian Shield, have been identified by reconnaissance rock geochemistry, inspection of ancient prospects, and interpretation of previous work. The ancient prospects of Abraq Shawfan, Abraq Shawfan South, Ad Du'ibi, Ad Du'ibi West, and Ad Dirabi are not recommended for further study. The Bald al Jimalah East ancient lead-silver mine should be drilled to investigate its mineral potential at depth and to.determine its apparent relationship to the nearby Baid al Jimalah West tungsten-tin prospect. High precious metal and copper contents confirmed at the Jarrar ancient prospect suggest additional study. Preliminary results of core and percussion drilling at the Bald al Jimalah West tungsten-tin prospect indicate that the mineralized rocks decrease in grade with depth and are not suitable for current economic exploitation. Geochemically anomalous areas in both plutonic and layered volcanic and clastic terrane are possible sites of significant base metal, molybdenum, tin, tungsten, and rare-earth element mineralization.
