Santana Minerals Limited’s updated pre-feasibility study for the Bendigo-Ophir Gold Project shows robust economics—with a 65% IRR at current gold prices—lower upfront capital, and accelerated cash flow. The refined plan paves the way for fast-tracked approvals and positions the project as an attractive investment in gold mining.

Santana Minerals Limited’s updated Pre‑Feasibility Study (PFS) for its Bendigo‑Ophir Gold Project presents an in‐depth vision of a 13.8‑year operation designed to generate robust cash flows even under conservative gold price scenarios. The updated study refines previous plans by downsizing the pre‑production capital expenditure to approximately A$277 million and by adopting a more selective open‑pit and underground mining strategy that focuses on near‑surface, high‑grade ore. Key highlights include operating margins supported by a base‑case net present value (NPV) of roughly A$780 million, with internal rates of return (IRR) climbing significantly at higher gold prices. The study forecasts initial gold production commencing within 15 months of starting construction, and the improved layout – featuring a 1.2Mtpa processing plant that retains optionality for scale-up – is expected to support annual outputs nearing 120,000 ounces during peak periods. Technical details provide reassurance on the project’s economics and engineering fundamentals. Updated metallurgy now forecasts an average recovery rate of 93% for the main deposit, and detailed cost estimates show an all‑in operating cost per ounce in the low A$1,600–A$2,100 range. The technical report outlines precise pit designs, dilution management, and geotechnical parameters across both open‑pit and underground operations. Advanced modelling techniques following JORC 2012 standards back the resource and reserve estimates, while comprehensive baseline environmental studies and proposed rehabilitation measures underscore the project’s low‑emission and sustainable credentials. Beyond the engineering and financial metrics, the study details a streamlined regulatory pathway. Santana Minerals plans to leverage New Zealand’s fast‑track approvals framework to secure its mining permits and related resource consents within an estimated six‑month timeframe. Funding remains a key focus as the board stresses its strong capital structure and ongoing discussions with multiple potential financiers to secure a balanced debt–equity package. Bullish sentiment centers on the project’s strong free cash flow generation, favourable IRRs even at conservative gold prices, and reduced upfront capital commitments. The comprehensive technical re‑assessment and strong historical drilling results add further confidence to the long‑term viability of the project. However, bearish concerns remain regarding regulatory and permitting uncertainties, potential delays in financing, and inherent risks associated with mine ramp‑up, dilution management, and environmental compliance. As always, investors should weigh these factors carefully when considering exposure to Santana Minerals Limited’s gold development strategy.
