Areas with mineral resource potential in the Thaniyah and Al Ufayriyah quadrangles in the central Precambrian Shield of Saudi Arabia have been identified by reconnaissance rock geochemistry and inspection of ancient prospects.
Locally anomalous areas in plutonic terrane have been defined as possible sources of tin, molybdenum, or base metal mineralization. The survey over layered volcanic terrane identified several areas of anomalous copper and zinc. One ancient copper prospect with gossan in the west-central part of the Thaniyah quadrangle merits additional study.
