Environmental Scoping Kicks Off Tunkillia PFS & ML Programs
Barton Gold Holdings (BGDFF) has initiated environmental scoping work for its Tunkillia Gold Project in South Australia, following the publication of its Optimised Scoping Study (OSS). The project shows promising metrics with projected total production of 942,000 oz gold and ~2M oz silver, with average annual production of ~120,000 oz gold and ~250,000 oz silver.
The project's financial highlights include A$2.7 billion in operating free cashflow, an NPV of A$1.4 billion (at 7.5% discount rate), a 73% IRR, and a 0.8-year payback period. A 'Starter' pit is expected to produce ~206,000 oz gold for A$825 million operating free cash in the first 13 months. The company has engaged ERIAS Group to prepare an environmental Scoping Report, a crucial step toward Mining Lease approval in South Australia.

Barton has now engaged the ERIAS Group to prepare an environmental 'Scoping Report', which is the first step in the environmental and Mining Lease (ML) approvals process in South Australia. Once agreed with South Australia's Department for Energy and Mining (DEM), the Scoping Report will set out the agreed scope of works for Tunkillia environmental assessments which will then support a future ML application.
Commenting on the appointment of ERIAS Group, Barton MD Alexander Scanlon said:
"Tunkillia's new Optimised Scoping Study has confirmed a large-scale, competitive gold and silver operation with significant economies of scale offering strong financial and capital leverage to a rapidly evolving gold market.
"We are accelerating Tunkillia in parallel with studies for 'Stage 1' operations leveraging our Central Gawler Mill. Our goal is to transition to 'producer' from 2026, generate cash flows, and then use these to develop Tunkillia as our 'Stage 2' expansion project for a lower-cost, lower-risk and lower-dilution pathway to 150,000ozpa gold.
"We are pleased to work with ERIAS as a leading South Australian environmental and social impact advisor."
