The Jibal Qutman Gold Project Kingdom of Saudi Arabia Deposit-Scale Structural Models in an Underexplored Terrane to Drive Discoveries
Slide 2: Gold and Minerals Company
Gold and Minerals Company Gold and Minerals Co. is a JV between Abdulrahman Saad Al Rashid (ARTAR) and KEFI Gold and Copper (KEFI) Set up in 2009 to explore the Saudi Arabian portion of the Arabian Nubian Shield Two major discovery projects at Hawiah (29.0Mt Cu/Au VMS) and Jibal Qutman (700koz+ orog
Slide 3: Arabian Shield Geology
Arabian Shield Geology Complex amalgamation of older western intra-arc volcanic terranes and younger eastern continental margin arc terranes. Heterogeneous orientation of greenstone belts between terranes with diverse geodynamic responses to regional strain and accretion. Jibal Qutman Modified after
Slide 4: Jibal Qutman Gold Project
Nabitah Deformation Zone Jibal Qutman Gold Project 4K The Nabitah suture is defined as a wide deformation zone characterized by multiple thrust faults, ophiolites, zones of high 3K strain and complex internal geometries. Red Hill Main Zone Trend Trend Red Hill Main and West South Modified after USGS
Slide 5: Jibal Qutman Gold Project
Nabitah Deformation Zone Jibal Qutman Gold Project 4K Jibal Qutman is a typical orogenic ‘mesothermal’ shear hosted gold deposit. 3K The mineralised system is closely related to the N-S striking Nabitah deformation zone, hosted within a suite of intermediate to ultramafic Red Hill volcanic and volca
Slide 6: Structural Geology – Main Zone trend
Structural Geology – Main Zone trend D1 Asir Terrane Accretion • Mean planes on stereonets define fold limbs; intersection defines F2 axial hinges. 3K • Foliation interpreted as folded S1. 3K D2 Dextral transpression during Nabitah Orogeny • Pervasive, anastomosing S2 foliation. D2 • North striking
Slide 7: Structural Geology – Red Hill trend
Structural Geology – Red Hill trend D2 Dextral transpression during Nabitah Orogeny • NW trending F2 folds with associated axial planar S2 regional fabric • North-South trending thrust fault – Shear fabric crosscuts S2. • SE-plunging fold axes D3 Najd reactivation of Red Hill Thrust • Late sinistral
