Several gold prospects require additional work, in particular geochemistry on pit or shallow auger/R.C-drill samples to look below the eolian sand, and resistivity, in order to increase the reserves of this very promising district.
The nickel-rich parts of the gabbro intrusion of Jabal Jedair should be reanalyzed for PGE.
Mineralization styles, in the following general paragenetic sequence, include (1) quartz-molybdenite veins in and near the granite stock, (2) low-grade gold-bearing quartz vein breccia in and along the margins of the granite stock, (3) gold-bearing stockwork and sheeted quartz veins, and (4) massive to banded gold-rich tabular quartz veins. The gold-bearing stockwork, sheeted, and tabular veins are generally spatially associated with square quartz porphyry dikes and more distal to the granite stock. Mineralized zones at Ad Duwayhi are characterized by low sulfide and base metal content and gold/silver ratios of approximately 6/1. Gold shows no significant correlation with other metals, except lead, and moderate correlation with silver.
