QMines Unveils Key Mt Chalmers Developments Amid Market Surge

QMines Limited has unveiled a sharpened development strategy for its flagship Mt Chalmers Copper-Gold Project, positioning the company for accelerated production timelines and multiple value inflection points throughout 2026. Furthermore, the strategic reset builds upon the strong foundation of the April 2024 Pre-Feasibility Study whilst capitalising on dramatically improved market conditions that have transformed the project's economics. These developments at Qmines Ltd for Mt Chalmers demonstrate the company's commitment to value creation through disciplined execution.

The company has adopted a disciplined, single-asset approach targeting 1 Mtpa processing capacity in a phased development that prioritises speed to cashflow whilst maintaining expansion optionality. This strategic pivot comes at an opportune time, with copper prices surging 32% to approximately US$13,000/t, gold climbing 130% to around US$5,400/oz, and silver skyrocketing 310% to roughly US$116/oz since the original PFS assumptions.

Compelling Economics Drive Strategic Reset

The Mt Chalmers PFS delivered robust fundamentals that have only strengthened with improved market conditions:

The strategic reset leverages these strong fundamentals whilst responding to five core drivers: copper-led development focus, fastest path to cashflow, low complexity execution, streamlined approvals pathway, and phased development with growth optionality. In addition, these improvements directly enhance project viability without requiring fundamental changes to mine design.

Management Insight:
"This strategic reset is about discipline and execution. By adopting a single-asset, expandable 1 Mtpa development strategy, we are prioritising the fastest and lowest-risk pathway to first production and cashflow, whilst preserving meaningful upside for our shareholders." – Andrew Sparke, Executive Chairman

Market Tailwinds Create Compelling Investment Case

The transformation in market conditions since April 2024 has dramatically enhanced Mt Chalmers' economic profile. However, these developments at Qmines Ltd for Mt Chalmers extend beyond simple price improvements:

Treatment and refining charges have declined significantly, with copper TC/RCs dropping to US$0/t from the PFS assumption of US$40/t, and zinc TC/RCs falling 50% to US$80/t. Consequently, these improvements directly enhance revenue and margins without requiring changes to mine design or process flowsheet.

Understanding Treatment Charges: A Key Economic Driver

Treatment Charges (TCs) and Refining Charges (RCs) represent fees paid by miners to smelters for processing concentrates into refined metals. These charges form a critical component of project economics, particularly for base metal projects.

When treatment charges decline, miners retain more revenue from their production. For instance, the current copper market demonstrates exceptional conditions, with benchmark treatment charges reaching zero levels. This means copper concentrate producers like QMines capture the full commodity price rather than paying processing fees.

The 100% reduction in copper TCs from the PFS assumption of US$40/t to current benchmark levels of US$0/t translates directly to improved project cashflows. Similarly, the 50% decline in zinc TCs enhances revenue from zinc concentrate production at Mt Chalmers.

These charge reductions reflect tight concentrate markets where smelters compete for material, benefiting mining companies through improved pricing terms. For QMines, this creates a more favourable economic environment without requiring operational changes.

Strategic Advantages of Phased Development

The adopted strategy delivers multiple competitive advantages across execution, financial, and operational dimensions. Furthermore, this approach aligns with current market preferences for de-risked development strategies.

Execution Benefits:

• Reduced technical and permitting complexity
• Improved schedule and cost confidence
• Faster regulatory approvals pathway
• Lower upfront capital requirements

Financial Benefits:

• Accelerated cash generation

The phased approach allows QMines to commence at manageable scale whilst preserving ability to expand processing capacity over time, subject to operating performance and market conditions. In addition, this strategy reduces execution risk compared to larger-scale developments whilst maintaining upside potential for shareholders.
