QMines Ltd Feasibility Study Mt Chalmers Advances Production Timeline

QMines Advances Toward Production as Definitive Feasibility Study Launches for Mt Chalmers

QMines Limited (ASX: QML) has taken a decisive step toward becoming a copper and gold producer, formally commencing the Qmines Ltd feasibility study Mt Chalmers for its flagship project in Central Queensland. This milestone represents the company's most significant advancement since releasing its Pre-Feasibility Study in April 2024, positioning QMines for a potential development decision and transition from explorer to producer.

The Mt Chalmers project, located just 20 kilometres east of Rockhampton, is a shallow, high-grade historic copper and gold mine with proven reserves of 9.6 million tonnes grading 0.65% copper and 0.48 g/t gold. Furthermore, the DFS will evaluate a 1 million tonnes per annum processing operation designed to accelerate cashflow generation through a staged development approach.

Accelerated Path to Production Creates Multiple Advantages

QMines has strategically designed its development approach around a 1Mtpa base case operation, deliberately choosing speed to market over maximum scale in the initial phase. This decision reflects management's focus on capital efficiency and risk reduction while positioning the company to benefit from current strengthening commodity cycles.

"Commencing the DFS is a defining milestone for QMines and represents a clear step toward bringing the Mt Chalmers copper and gold mine back into production. With feasibility workstreams accelerating across the Project, we are methodically advancing the technical, environmental and planning foundations required to support development." – Andrew Sparke, Executive Chairman

Key Strategic Benefits of Phased Development:

• Reduced upfront capital requirements through smaller initial scale
• Simplified execution minimising development complexity
• Earlier cashflow generation to strengthen financial position
• Reduced reliance on future equity raises limiting shareholder dilution
• Self-funding capability for exploration and growth initiatives
• Market timing advantage to capture current copper and gold cycle strength

The staged approach is expected to materially strengthen QMines' strategic position by bringing Mt Chalmers online during the current strengthening phase of the copper and gold cycle. This timing allows shareholders to participate in the upside potential associated with improved commodity pricing sooner, whilst supporting the company's ability to self-fund future exploration and growth initiatives.

Comprehensive DFS Workstreams Now Underway

The company has activated feasibility studies across multiple technical disciplines, demonstrating the breadth and depth of work required to support a future development decision. In addition, current workstreams include:

Technical Studies:
• Independent third-party reviews and gap analyses on 2024 PFS components
• Mine planning and optimisation scope development
• Process plant design planning and consultant selection
• Tailings storage and infrastructure design pathways
• Draft feasibility budget and cashflow modelling
• Project risk management framework development

Environmental Programs:
• Summer flora and fauna surveys commencing shortly
• Groundwater monitoring programs beginning
• Environmental baseline studies throughout 2026
• Environmental approval submissions targeted from 2027

The parallel execution of these workstreams reflects QMines' systematic approach to project advancement, ensuring all critical components progress simultaneously rather than sequentially. Consequently, this methodology is designed to reduce overall development timelines whilst maintaining comprehensive technical and environmental evaluation standards.

Understanding Definitive Feasibility Studies: The Final Gateway to Development

A Definitive Feasibility Study represents the most comprehensive technical and economic evaluation of a mining project before development decisions are made. Unlike earlier studies that establish broad viability, the Qmines Ltd feasibility study Mt Chalmers provides the detailed engineering, environmental, and financial analysis required by boards, lenders, and regulatory authorities.

Why DFS Matters to Investors:
The DFS serves as the foundation for final investment decisions, detailed project financing, and regulatory approvals. Furthermore, a positive DFS outcome typically triggers significant re-rating of development companies as the project transitions from "possible" to "probable". For QMines, successful DFS completion could represent the difference between exploration valuation and near-production valuation multiples.

Key DFS Components Include:
• Detailed mine plans with production scheduling
• Process plant engineering and capital estimates
• Infrastructure requirements and costs
• Environmental impact assessments
• Economic modelling with sensitivity analyses
• Risk assessments and mitigation strategies

The DFS process typically takes 12-18 months to complete, involving detailed technical studies across mining, metallurgy, environment, and economics. However, this comprehensive evaluation provides the technical foundation for project financing and regulatory approvals, marking the final step before potential construction decisions.

Substantial Resource Base Supports Long-Term Operations

QMines controls an impressive resource inventory across its Queensland portfolio, providing both immediate development opportunities and long-term growth potential:

Mt Chalmers Ore Reserves:
• Proved Reserves: 5.1Mt @ 0.72% Cu, 0.58 g/t Au
• Probable Reserves: 4.5Mt @ 0.57% Cu, 0.37 g/t Au
• Total Reserves: 9.6Mt @ 0.65% Cu, 0.48 g/t Au

The reserve base underpins approximately 10 years of production at the planned 1Mtpa rate, with additional resources providing expansion potential and mine life extension opportunities. For instance, the Mt Chalmers deposit represents a high-grade historic mine that produced 1.2Mt @ 2.0% Cu, 3.6g/t Au and 19g/t Ag between 1898-1982, demonstrating the deposit's proven production capability.
