About the Tomingley Gold Extension Project
Alkane seeks to extend mining to two newly defined gold deposits immediately south of the current Tomingley gold mine. The purpose of the project is to provide new ore feedstock for the existing processing plant at Tomingley Gold Operations (TGO) and extend its life by seven to ten years. The NSW government classifies this project as a State Significant Development (SSD). The proposed project design and rehabilitation plan will incorporate feedback from the local community, stakeholder groups, industry regulators and government agencies.
The key elements of the Tomingley Gold Extension Project are outlined below.
Open cut and underground mining
A single open cut combining the adjacent San Antonio and Roswell deposits (the SAR open cut) will be up to 1.7km long, 700m wide and 310m deep. We expect to mine this open cut in stages to allow progressive rehabilitation. We also plan to develop an underground mine, with a portal within a completed stage of the SAR open cut.
Processing of the ore will take place at the existing TGO processing plant. We plan to establish a second residue storage facility (RSF) to the south of the existing RSF.
A proposed haul road will transport ore via the existing Newell Highway underpass from the SAR open cut to the TGO processing plant.
Waste rock and progressive rehabilitation
Two new waste rock emplacements in the vicinity of the SAR open cut will be established. We also propose to backfill the two Caloma open cuts and, in time, could backfill a completed stage of the SAR open cut.
We intend to undertake progressive rehabilitation of these waste rock emplacements to ensure they are returned to stable and productive ecosystems.
Newell Highway realignment
Since the San Antonio and Roswell deposits are underneath the current Newell Highway, TGO proposes to construct a new section of highway to bypass the development. The new section of highway will be built to the latest Austroads standards and incorporate several improved safety features.
Kyalite Road also needs to be realigned to accommodate the preferred 500m blast exclusion zone. These activities are being planned in close consultation with Transport for NSW, as well as Narromine Shire Council, residents and road user groups.
TGO has negotiated purchase of seven properties (approximately 2700ha) for this project. Some of this land holds the SAR deposit or is earmarked for waste rock emplacements and other supporting mine infrastructure. We also need some of the land for construction of the new sections of Newell Highway and Kyalite Road.
Once the new sections of road are open, TGO will gift the associated land to Narromine Shire. The balance of those properties (not needed for the mining operation) will be restored to a mix of agricultural land and biodiversity offsets (e.g. native bushland).
Upon conclusion of mining, the SAR mine site will be fully rehabilitated and restored to stable and productive ecosystems. We intend this to be a mix of biodiversity and agricultural production.
The timeline for this project to commence depends on the SSD approval process. Broadly, we anticipate the Environmental Impact Statement (EIS) to be completed and exhibited in early 2021. Following our response to submissions, the timing for assessment of the application is a matter for the NSW Department of Planning, Industry and Environment.
Since this project is an extension of our existing operations, we are working with the NSW government to expedite the approval process. TGO has an excellent track record and has demonstrated substantial benefits for the local community. We hope to obtain consent by mid 2021. Stakeholders and the local community can help by making a submission in support of the project at the public exhibition stage (early 2021).
Once we have consent, we’ll begin construction of the Newell Highway realignment, which is expected to take around seven months.
