Summary:

Rocks of the Al Amar region are part of the Ar Rayn Terrane, a regional tectono-stratigraphic unit. This unit is separated from the western Abt Schist Belt by the regional Al Amar-Idas fault. Rocks of the Ar Rayn Terrane are overlain by Paleozoic sedimentary rocks to the northeast and south.

The deposit is located in a north-south trending belt of felsic to mafic volcanic rocks comprising the Al Amar Group. Rocks of the Al Amar Group are transitional in composition from tholeiitic to calc- alkaline. The rocks are comprised of volcanics, submarine exhalatives, carbonates and cherts. The Al Amar Group rocks are intruded by granodiorite, trondhjemite, gabbro and quartz diorite rocks coeval or following tectonism of the group dated at 700Ma to 600Ma. Post tectonic granites dating 580Ma also intrude the Al Amar rocks. The metamorphic grade of rocks in this region ranges from lower greenschist facies to the west and amphibolite facies to the east.

Structurally the Al Amar Group rocks have been subjected to complex folding and faulting. Predominant structures trend north-south and northeast-southwest. Structures at the Al Amar deposit are dominated by northwest-southeast and west northwest-east southeast fault systems and are associated with mineralisation.

Three spatially discrete zones of mineralisation have been identified at Al Amar. The main mineralised zone is the North Vein Zone (the “NVZ”). This zone strikes east-west with a dip of 69° to ........


Mining Methods

  • Longhole open stoping
  • Backfill


Summary:

Mining Operations assume using a fully mechanised long-hole open stoping method with subsequent backfilling using waste development. For the lower (<790mRL) levels of the mine the level spacing will be reduced from 30m to 20m and the mining sequence changed from a “bottom-up” approach to a “top-down” sequence utilising rib pillars for additional local and regional support. Access to the mine is by a new primary decline to the main production levels extending some 300m below surface to the 590mRL.
