Guyan Gold Project


Location: Southwest Saudi Arabia

Mine type: Open pit and underground

Metals: Gold

Desposit type: Orogenic gold


Jabal Guyan is a gold deposit located in the Arabian Peninsula, southwest Kingdom of Saudi Arabia. It lays about 414 km away from Jazan Port on the Red Sea, connected to Najran by a newly paved road, and 835 km away from Jeddah. The nearest communities of significant size are Khamis Mushayt which is 190 km away, Abha to the West is 220 km away and Najran to the South-East is approximately 100km away from the project site.

Geology and Mineralisation

Jabal Guyan mineralization is orogenic type gold deposit. It is hosted within Proterozoic rocks (metamorphosed volcanic and volcanoclastic rocks with diorite, gabbro, tonalite, gneiss, granodiorite and granite intrusions). The deposit is composed of two sectors as North and South veins. Gold bearing quartz veins are associated with a pair of parallel shear zones developed within metamorphosed tuff and andesites. Gold mineralized veins pinch and swell both laterally and vertically along the length of the shears. Mineralization extends along NW-SE direction. Strike lengths of the mineralization are 1430 meters for the north vein and 900 meters for the south vein. Mineralization extend is tested for 200 meters depth from surface.

High grade quartz veins are surrounded by altered, sheared intermediate tuff having disseminated gold mineralization. Native gold occurs as minute, discrete, scattered flakes within the quartz veins or as small inclusions, most commonly in pyrite and arsenopyrite. Alteration includes chlorite, sericite, epidote and late stage carbonate veining.


Jabal Guyan orogenic gold deposit has more than 150,000 oz geological resources with Au grade of 4.69 g/t. Feasibility Studies for mining and processing are ongoing to identify the mineable and saleable reserves. The Guyan orebody is still open at depth and extension with significant ore occurrences in the nearby satellite veins.


Jabal Guyan gold deposit has significant exploration potential along strike and dip extensions. Drilling program currently continues to increase the geological resources.

 Moreover, 103 quartz veins have been identified in the mining and exploration licenses and 23 of them carriy significant indicators of gold mineralization. Potential targets have been tested by geochemical prospection. Al Aqiq and Fatma prospects have significant exploration potential with the presence of historical mining activities and high-grade gold bearing core and rock chip samples.
