OreCorp (ORR) is set for the next round of drilling at Nyanzaga gold project in Tanzania. The West Australian based mineral company announced it is working closely with the Government of Tanzania to progress the project to deliver the country’s first new “large scale gold mine in over a decade”.
A drilling campaign across the project area will consist of reverse circulation drilling at the Kilimani deposit, diamond drilling west of the Nyanzaga deposit and aircore drilling to the west and northwest of the special mining licence area.
Mineralisation at Kilimani is said to be hosted within oxidised zones of a 50 to 150 metre thick sequence of mineralisation. It is also structurally controlled by a fault zone which acts as a conduit feeder zone. A total of 15 drill holes are planned at Kilimani, covering around 3260 metres to test the deep feeder structures. The firm anticipates to gain a better understanding of the geology and continuation of the mineralisation at Kilimani.
To the west of the Nyanzaga deposit, four diamond holes are planned for 1250 metres to improve confidence in an underground design. ORR is looking to better understand the weathering profile for the box cut and portal, and will also test the ground conditions along the planned decline and ventilation rise positions.
The company also believes there is potential for significant new discoveries within the special mining licence boundary and has planned 149 aircore drill holes in the northwest, and 116 drill holes in the western corridor.
The upcoming program follows drilling at the Kilimani deposit completed in March this year, which defined thick shallow zones of mineralisation. Interpretation of the work completed so far indicates the Kilimani and Nyanzaga systems are linked which ORR said is a pattern being recognised as the hallmark of some of the largest gold deposits globally.
