OreCorp Limited (ASX:ORR) has commenced a large follow-up drilling programme at the Nyanzaga Gold Project in Tanzania.
The drilling programme will comprise Reverse Circulation (RC) drilling at the Kilimani Deposit to test the location of the deep feeder systems, Diamond (DD) drilling west of the Nyanzaga Deposit to improve confidence in the underground design and a large regional Aircore (AC) programme in the west and northwest of the Special Mining Licence (SML) area.
The programme is anticipated to take four months to complete and will comprise approximately:
· 15 RC holes for 3,260m to test the deep feeder structures at Kilimani;
· 4 DD holes for 1,250m to improve confidence in the underground design; and
· 265 AC holes for 13,250m for regional exploration.
Matthew Yates CEO and Managing Director, Matthew Yates, said the vompany is very pleased to be commencing further drilling at Nyanzaga and continues to work closely with the Government of Tanzania to enable the progression of Nyanzaga and ultimately deliver the country’s first new large-scale gold mine in over a decade, for the benefit of all stakeholders.
Kilimani is located approximately 450m northeast of the Nyanzaga Deposit and within the SML area.
CSA Global UK Ltd (CSA Global) recently completed an updated Kilimani Mineral Resource Estimate (MRE) which has been classified and reported in accordance with the JORC Code.
The updated Kilimani MRE is a combined Indicated and Inferred Mineral Resource of 6.27 Mt @ 1.06 g/t Au for 213 koz of gold. The Kilimani MRE is exclusive of and in addition to the Nyanzaga Measured, Indicated and Inferred MRE of 23.70 Mt @ 4.03 g/t Au for 3.1 million ounces of gold.
The mineralisation at Kilimani appears to be preferentially hosted within the oxidised zones of a distinctive 50 to 150m thick sequence of stratabound altered coarse grained sandstones and epiclastics with interbedded narrow siltstones, mudstones and chert units which are part of the Kilimani Group.
The mineralisation is also structurally controlled by the Kilimani Fault Zone which acts as a conduit feeder zone. The mineralised zones have been offset by northeast cross faults.
Proposed drilling at Kilimani will include 15 RC holes for 3,260m to test the location of deep feeder systems, one to the east and one to the west of the known deposit. The holes will increase the understanding of the geology and mineralisation continuity at Kilimani.
Nyanzaga DD Drilling
Four DD holes for 1,250m are proposed to the west of Nyanzaga Hill to improve confidence in the underground design. These will be drilled with the aim of:
· Improving the understanding of the weathering profile for the Box Cut and Portal
· Testing the ground conditions along the planned decline and ventilation rise positions
· Identifying the location and thickness of the thrust fault and the depth and thickness of weathering
One of the holes will be drilled to 600m to confirm the location of previously untested, favourable host sequences of the C1 chert near an interpreted second anticlinal hinge zone and immediate eastern limb area, 300-400m west of the currently defined Nyanzaga mineralisation.
Exploration Drilling
The company believes that there is potential for significant new discoveries within the SML boundary and has planned a large regional AC program in the west and northwest of the SML area.
The drilling in the northwest will comprise 149 holes for 7,450m along 9 lines at 200m x 50m spacing with a further three infill lines at 100m x 50m spacing. The drilling in the western corridor will comprise 116 holes for 5,800m along 8 lines at 400m x 50m spacing.
The company is very pleased to be commencing further drilling at Nyanzaga and continues to work closely with the Government of Tanzania to enable the progression of Nyanzaga and ultimately deliver the country’s first new large scale gold mine in over a decade, for the benefit of all stakeholders.
