The permit covering 1242ha includes port operations, a haulage road and the mine site, which has been approved to mine up to 6 million tonnes per annum of coal.
Once the initial site is developed, the mining department will review future extensions to meet planned production.
Chairman Peter Lynch said: "We are pleased that the final stage of the forestry permitting process is now complete. With the delays in finalising the permitting process now behind us, we can now look to the future and focus our efforts on the delivery of the project.
"After the establishment of the initial 2Mtpa operation, we have the ability to expand up to 6Mtpa of premium coking coal operation and this considerably increases our confidence in the success of this project and consequently bringing increased value to shareholders."
