Low Capex and High Grade: NMG’s Crown Prince Faces Execution and Price Risks

Feasibility Study Highlights

New Murchison Gold Limited (ASX:NMG) has delivered a compelling Feasibility Study (FS) for its Crown Prince Gold Deposit, part of the Garden Gully Gold Project near Meekatharra, Western Australia. The study outlines a pre-tax cash flow of $226 million over a 30-month mine life at current spot gold prices (A$4,385/oz), underscoring the project's strong financial potential.

Remarkably, the capital expenditure (capex) required to commence production is a modest $5.4 million, a figure notably low compared to peer projects. This is largely due to NMG’s Ore Purchase Agreement (OPA) with Westgold Resources Limited, which allows ore to be trucked directly to Westgold’s Bluebird Mill for processing, eliminating the need for on-site processing infrastructure.

Ore Reserve and Mining Plan

The FS reports a maiden Ore Reserve estimate of 0.89 million tonnes grading 4.8 g/t gold, containing approximately 140,000 ounces. Mining is planned exclusively as an open pit operation, with a stripping ratio of 21:1 waste to ore. The mining schedule anticipates commencement in June 2025, with first ore sales expected by August 2025.

Ore will be crushed and sampled on site before haulage to Westgold’s Bluebird Mill, leveraging existing infrastructure and reducing upfront capital requirements. The project’s relatively high grade, particularly in the newly discovered Southeast Zone, supports early positive cash flows.

Financial Metrics and Sensitivities

Financial modelling within the FS demonstrates robust returns, with a post-tax net present value (NPV) of $156 million at an 8% discount rate using spot gold prices. The internal rate of return (IRR) is exceptionally high, exceeding 1,000% at spot prices, reflecting the project’s short mine life and low capital intensity.

Sensitivity analyses confirm the project’s resilience to fluctuations in gold price and operating costs, though a gold price drop exceeding 10% would materially reduce ore tonnage and project value. NMG also plans to utilise its substantial accumulated tax losses to offset initial tax liabilities, enhancing cash flow.

Environmental and Regulatory Progress

NMG has submitted all key mining and environmental approvals, including the Mining Proposal and Mine Closure Plan, with regulatory assessments underway. The project area has undergone extensive environmental baseline studies, confirming minimal impact on flora, fauna, and groundwater systems. Native Title and heritage agreements are in place with the Wajarri Yamaji Aboriginal Corporation, and no significant cultural heritage issues have been identified.

Next Steps and Outlook

Looking ahead, NMG is advancing contract tenders for mining, crushing, haulage, and infrastructure works, aiming to finalise arrangements ahead of mining commencement. The company also plans to explore underground potential beneath the open pit and evaluate adjacent deposits such as Lydia and New Murchison King to extend the resource base.

CEO Alex Passmore highlighted the project’s streamlined path to production and the strategic advantage of the OPA with Westgold, which significantly reduces capital requirements and accelerates cash flow generation. The Crown Prince Deposit, though modest in size, offers high-grade ore close to surface, positioning NMG for rapid progress in 2025.
