The closure of the Ravensworth underground coal mine has been pushed back in an effort to secure miners new jobs.
In March Glencore announced that it would stop production at the Hunter Valley underground mine this month "due to the increasingly difficult economic conditions the mine is experiencing".
A Glencore spokesperson stated at the time that "continued operations were no longer financially viable due to combination of lower prices, higher production costs at the mine, a strong Australian dollar and geological constraints in future mining areas".
The underground complex employed around 130 full time workers, and three contractors.
However the miner has reportedly suspended the closure date to late October, according to the ABC.
The miner has been in talks with unions, and explained that it aims to retain workers due to their experience, which would be lost to the industry if they were made redundant.
Glencore was contacted for further comment but was unavailable at the time of publishing.
Last week Glencore also announced that it would cut approximately 100 jobs from its Clermont coal operations in Queensland.
