   Resource & Grade:
   The Al-Hajar deposit occupies two adjacent hills, and is amenable to surface mining. Beneficiation and metallurgical tests have indicated that recovery rates for gold is up to 80%, while silver recovery is only 30% as most of the silver is hosted in jarosite, an iron oxide which is not amenable to leaching. The area is also known to contain other resources. Plans are being formulated to mine the resources as a satellite operation to Al-Hajar, now in full commercial production.
