Next month, Tamboran Resources intends to drill an exploratory borehold near Belcoo in order to collect rock samples
A vigil has been held at the quarry by protesters against the controversial fracking technique.
Protesters have set up what they call the Belcoo Community Protection Camp outside the entrance and say they want their protest to be peaceful.
A four-month lease has been taken out by Tamboran to carry out the drilling work in the quarry owned by Acheson and Glover.
The company said the extension was granted due to "unlawful incidents".
Tamboran were granted a court order last Friday that prohibits people from entering or occupying land at Gandrum Road, obstructing access to the site, or preventing Tamboran from carrying out exploratory mining operations.
A spokesman for Tamboran Resources said: "The company has since sought and secured an extension to the order on Wednesday 30 July following additional unlawful incidents that took place since the initial order was served."
