TPG Telecom is signing up more resources companies to private mobile networks, edging into industries dominated by Telstra after handing over a new network to coal miner Yancoal in NSW’s Hunter Valley.

The telecoms group, which won its first private mobile network contract last year – with Yancoal – is understood to have signed contracts with two other resources groups, including a gold mining company, in the past few weeks. It considers expansion into private networks a strategic priority.
