Red River Resources has suspended underground mining at its Far West mine in North Queensland after a fall of ground.

The Queensland Mines and Quarries Inspectorate has begun an investigation into the cause of the incident, which occurred on Tuesday, resulting in a worker being taken to hospital.

“RSHQ’s vision is zero serious harm; workplace accidents that result in injuries requiring hospitalisation are always of concern,” a Resources Safety and Health Queensland spokeswoman said.

In a written statement on the incident, the company said an operator had received a precautionary medical examination and was subsequently discharged with no serious injuries.

The Far West deposit is part of Red River’s Thalanga operations, about 65km south-west of Charters Towers.

Thalanga’s site headcount during the June quarter was 140 people.

This included 64 full-time Red River Resources employees and an additional 76 contractors working in exploration and mining.

Thalanga operations processed 90,000t of ore grading 1.2 per cent copper, 1.5 per cent lead, 4.4 per cent zinc, 0.2 g/t gold and 38 g/t silver (10.6 per cent Zn Eq.) in the last quarter.

Copper concentrate production for the quarter was 3342 DMT. Zinc concentrate production for the quarter was 6111 DMT zinc and lead concentrate production came in at 1356 DMT.
