ABB awarded $24 million mine hoist contract in Australia

Newmont has commissioned ABB to design, supply, install and provide long-term service for the entire mine hoist mechanical and electrical systems for the mine production shaft at Tanami. The gold mine is located in the Tanami Desert, 563km north west of Alice Springs and 949km southwest of Darwin in Northern Territory, Australia.
The $24 million AUD ($17 million USD) contract marks part of Newmont’s Tanami Expansion 2 project which is expected to increase the annual capacity of the processing site to 3.5 million tonnes per annum from 2.6 million tonnes and extend the life of the mine beyond 2040. Over a 90-week period, ABB will deliver two complete mine hoist systems; a double drum personnelriding hoist and a friction hoist.
Currently, ore is trucked from the Tanami underground mine to the surface via a system of declines, which presents logistical, ventilation and cooling requirement challenges and constraints to the planned expansion of the mine.
“The Tanami expansion project includes construction of a 5.4 meter shaft that can reach 1,460 meters below surface depth to enable recovery of ore at a depth,” said Neil Steyn, regional project director at Newmont. “This provides a viable solution to extend the mine and with an additional investment in processing is expected to increase production to 3.5 million tonnes per year. ABB’s in-house mechanical hoist design capability will help deliver a tailormade solution in a cost-effective way.” Chilean miner chooses German conveyor maintenance vehicles
The Chilean state mining company Codelco, the world’s largest copper producer, has become the launch customer for the newly developed HG16 maintenance vehicle from GHH, the German manufacturer of mining and tunnelling machinery.
The first vehicle has already been shipped, with three more to follow. The HG16 will be used to maintain the powerful conveyor belt at the Chuquicamata mine, one of the largest in the world, with production of 385,000 tonnes of copper ore per year.
A 7 km long conveyor belt rises 1 km from the underground extraction site to the surface, where a 6 km long conveyor belt then runs to the interim storage facility.
The HG16 is a four-wheeled crossover, conveyor belt maintenance vehicle equipped with loading platform, working platform and loading crane, capable of lifting almost a ton. The working platform, which can be extended to a length of 4.9 metres, can be slewed through 95 degrees to cover a large working area.
Callinex Mines has commenced its 2020 summer drilling campaign at its Pine Bay Project, 10 miles from processing facilities in the Flin Flon Mining District of Manitoba.
The campaign will complete up to 1,500m of drilling at the Project to test two newly identified borehole pulse electromagnetic anomalies (BPEM). These are interpreted to be off-hole from sulphide stringers that include copper, zinc, gold and silver mineralization and within the same mine horizon that hosts the Sourdough VMS deposit and the past producing Centennial Mine.
