Summary:
The CSH217 deposit is a large bulk tonnage low grade style of gold mineralization hosted within a ductilebrittle shear zone in Proterozoic sediments. Earlier property work and recent drilling data suggest that the gold mineralization was emplaced along the major southwesterly trending ductile-brittle shear zone. The ductile-brittle shear zone, which crosscuts the original bedding structure at about 10º, controlled the mineralization.
The shear zone is parallel to the foliation of the regional metamorphism, which is also parallel to the synclinal fold axis and deformation style typical of many greenstone and slate-belt terranes. Folding continued beyond the point of rupture, with the strain taken up in the developing shear zone. The quartzsulphide veinlets are boudinaged within the foliation and were clearly deposited early in the deformational history and are perhaps related to basin dewatering during regional folding, typical of “Slate Belt” gold districts.
The host rocks to the gold mineralization on the CSH217 property are mainly carbonaceous phyllite, schist, and slate within the lower members of the Bilute Formation.
The gold mineralization is composed of thin (1 to 10 mm) sulphide and quartz-sulphide seams/veinlets, stringers, and boudinaged lenses, which are concordant with the bedding and foliation and trend along the shear zone. Much quartz vein material has been logged in the drill holes associated with the higher grade gold sectio ........
Summary:
The CSH Gold Project has two open-pit mining operations and was operating at a 30,000 tpd capacity during Phase I. The Company completed Phase II expansion construction and entered into commercial production in the fourth quarter of 2014. Since the commencement of Phase II commercial production, CSH has increased its processing capacity to 60,000 tpd. As part of the Phase II expansion, a second heap leach pad was created with a valley between the initial Phase I heap leach pad and the newly created Phase II heap leach pad.
In July 2019, CSH updated its mine plan based on a result of the latest ultimate limit optimization, in which the production rate was reduced to 40,000 t/d with a life of mine ("LoM") of seven years as of 2019.
