At Jabal Sayid mine in Saudi Arabia, brownfields drilling delineated a very high-grade extension to the Lode 1 deposit. Meanwhile one kilometer south of Lode 1 at the Janob target, first pass exploration drilling discovered a new zone of ore grade copper mineralization, highlighting the potential along the multiple prospective and largely untested paleosurfaces on the project. |

Summary:
Jabil Sayid is located in the prospective Neo-Proterozoic Arabian Shield. The shield continues west of the Red Sea into Egypt and Sudan as the Nubian shield. The rocks are 600 to 1,000 million years old, and contain two major structurally controlled mineralised zones; the Samran Shayban Mineral Belt, which extends from Sudan, north-east past Mahd Adh Dhahad, and a second, parallel north-east trending Wadi Kamal Mineralised zone, which extend from the Nile valley, in Egypt, into northern Saudi Arabia.
The shield has similarities to many mineralised Proterozoic shields around the world. The Arabian Shield hosts a wide variety of mineral systems including porphyry copper-gold, epithermal gold and volcanic hosted massive sulphide (VHMS) deposits, many of which are gold rich, and Ultramafic hosted nickel-copper deposits.
Jabal Sayid is a volcanic hosted massive sulphide (“VHMS”) system, lying within the Asir volcanic arc. The area is arid and mountainous. Two layers of volcanic rocks form the top of the structure with local deformation resulting in large folds filled with granite complexes. Mineralisation is hosted by felsic volcanic rocks associated with a local paleovolcanic centre and crosscut by intrusions. Three styles of mineralisation have been identified at Jabal Sayid: stockwork zones, massive sulphides and sulphide breccia. Four separate mineralised lodes (Lodes 1, 2, 3 and 4) located within a northeast-trending corridor 1.2 kilometre long and betwe ........
