Summary

Ramelius Resources Limited reported a transformational year in FY26, marked by a 17% increase in Mineral Resources to 14Moz and a 79% increase in Ore Reserves to 4.3Moz as of June 30, 2026. Key milestones included the successful integration and commercial production at the Dalgaranga Gold Mine, a positive Definitive Feasibility Study for the Rebecca-Roe Gold Project, and a significant upgrade to the Mt Magnet processing plant. The company also returned A$255.7 million to shareholders through dividends and a share buy-back program, reflecting strong financial performance despite a year-on-year decrease in gold production.

Reasoning: Ramelius Resources Limited reported a transformational year in FY26, highlighted by significant growth in its gold Mineral Resources and Ore Reserves, successful integration of the Dalgaranga Gold Mine, and a robust Definitive Feasibility Study for the Rebecca-Roe Gold Project. The company also demonstrated strong financial performance and returned capital to shareholders, despite a decrease in gold production and an increase in the Restricted Work Injury Frequency Rate.

Positive factors

  • Significant increase in Mineral Resources (17% to 14Moz)
  • Substantial increase in Ore Reserves (79% to 4.3Moz)
  • Maiden Ore Reserve for Never Never underground (1.6Moz)
  • Maiden Ore Reserve for Roe underground (260koz)
  • Positive DFS for Rebecca-Roe Gold Project (NPV5% of A$692 million, 1.1Moz Ore Reserve)
  • Mt Magnet plant upgrade to 5Mtpa capacity
  • Strong financial performance (AISC margin, underlying EBITDA)
  • Share buy-back program of A$250 million announced
  • Successful integration and commercial production at Dalgaranga Gold Mine
  • Initial metallurgical recoveries on Never Never ore better than modelled

Negative factors

  • Gold production decreased year-on-year (192,182oz vs 301,664oz)
  • Underlying NPAT decreased year-on-year
  • Total employee turnover rate is high (31%)
  • Restricted Work Injury Frequency Rate (RWIFR) increased

Low confidence — this extraction should be reviewed alongside the original source.

Facts used in scoring: 60

Resource Updateneutral

Revised estimate for an existing resource — compare to prior to assess progress.

Why it applies: The document provides updated Mineral Resources and Ore Reserves as of 30 June 2026.

Evidence · text

“Resources and Reserves 28 ... Mineral Resources 30 ... Ore Reserves 37”

DFS-Supportingneutral

Resource estimate prepared to support a Definitive Feasibility Study — requires high M&I confidence.

Why it applies: The Rebecca-Roe Gold Project DFS was completed, demonstrating robust financial returns and supporting a Final Investment Decision.

Evidence · text

“Ramelius released its Definitive Feasibility Study (DFS) on the Rebecca-Roe Gold Project on 28 October 2025.”

PFS-Supportingneutral

Resource estimate prepared to support a Pre-Feasibility Study — requires adequate M&I component.

Why it applies: A Pre-Feasibility Study was completed for the Never Never Underground Deposit, demonstrating strong economic returns.

Evidence · text

“On 28 October 2025, Ramelius released its Pre-Feasibility Study (PFS) on the Never Never Underground Deposit (including Pepper).”

High Recoverypositive · Story-specific tag

Recovery Improvingpositive · Story-specific tag

Recovery improved versus a like-for-like prior test program on the same domain and route.

Why it applies: Initial metallurgical recoveries on the Never Never ore have been better than modelled.

Evidence · text

“Initial metallurgical recoveries on the ore have been better than modelled.”

Cut-off Undisclosednegative

High-grade interval reported without stating the cut-off grade used for compositing.

Why it applies: The cut-off grades for most of the reported Mineral Resources and Ore Reserves are not explicitly stated in the tables.

Evidence · text

“Figures rounded to 2 significant figures. Rounding errors may occur.”

Reasoning: The Rebecca-Roe DFS demonstrates robust financial returns with a high NPV, strong IRR, and a 9-year mine life averaging 130koz pa, supporting a Final Investment Decision.

Positive factors

  • DFS-Supporting
  • High NPV
  • Strong IRR
  • Long Mine Life
  • High Recovery

Evidence · text

“The Rebecca-Roe DFS was announced on 28 October 2025. The key highlights from the DFS include: • Undiscounted cash flow, after tax, of $1,037 million (at a base case of A$4,500/oz) • After-tax net present value (NPV5%) of $692 million (at A$4,500/oz) • Internal rate of return (IRR) after tax of 34 percent (at A$4,500/oz) • Gold production averages 130koz pa over the Life-of-Mine at an AISC of A$2,625/oz • Mine Plan2 – A gold price of A$3,250/oz has been used for generation of open pit and underground cut-off grades – Open Pit - 21Mt at 1.3g/t for 0.88M ounces – Underground - 5Mt at 1.8g/t for 0.31M ounces – Total - 26Mt at 1.4g/t for 1.2M ounces – Mining commencement December 2027 quarter, with first gold production forecasted to commence in the December 2028 quarter, with an initial mine life of nine (9) years – Capital cost of $188 million for a 3.25Mtpa processing plant located adjacent to Rebecca – Average metallurgical recovery of 91.5 percent”

Reasoning: Circuit one of the Mt Magnet plant upgrade will process 1.3 Mtpa at a finer grind size of 53μm to achieve optimal recoveries of 92.4% from Dalgaranga ore.

Positive factors

  • Plant Upgrade
  • Improved Recovery
  • Optimized Grind Size

Evidence · text

“Circuit one will comprise repurposing and refurbishing the existing Mt Magnet 1.9Mtpa plant down to 1.3Mtpa and reduce the current grind size from 175 micrometres (μm) to 53μm which will allow optimal recoveries from the Dalgaranga ore. Circuit two will comprise a new 3Mtpa circuit at a grind size of 175μm to process Mt Magnet ore sources. This will include relocation and repurposing existing equipment from the Dalgaranga plant. The selected engineering solution and operational plan is estimated to deliver over $1 billion in synergies over the first 10 years of mine life.”

How Atlas produces this analysis

Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
