Overview

PNX Metals Limited (PNX) proposes to recommence mining of the Fountain Head open pit, which is situated on granted mineral leases north of the Mt Wells road between the towns of Pine Creek and Adelaide River, approximately 170km south of Darwin. Ore will be mined using traditional drilling and blasting techniques and gold extracted using a carbon-in pulp process. The life of mine is 3 years.

Stage 1: Notice of intent

On 16 March 2020 the NT EPA decided the Fountain Head Gold Project requires assessment under the Environmental Assessment Act 1982 at the level of Environmental Impact Statement (EIS).
