Introduction MEC Case Study: Helping Restore Mined Land for Future Handover Project Stream: Execution Project Stage: Environmental Management, Reporting & Monitoring Compliance Auditing Type of Mine: Open Pit Region: Western Australia Commodity: Bauxite The Challenge A major bauxite producer required botanical monitoring across rehabilitation areas established 25 to 30 years ago to assess progress towards approved mine closure and completion criteria. The challenge involved relocating historical monitoring plots within dense native vegetation and accurately assessing ecological recovery against surrounding undisturbed ecosystems. The outcomes would help determine whether rehabilitation areas were progressing towards eventual handback to the State, reducing long-term environmental liabilities and supporting [...]

Introduction MEC Case Study: Reducing Geotechnical Uncertainty Before Final Investment Decision Project Stream: Feasibility / Bankable / DefinitiveProject Stage: Due DiligenceType of Mine: UndergroundRegion: Queensland, AustraliaCommodity: Hard Coking Coal The Challenge A brownfields longwall underground development was being assessed to extend the life of an existing coal operation by transitioning from open cut to underground mining. The project targeted approximately 4.5–5 Mtpa of saleable hard coking coal production across an estimated 23-year mine life. The key challenge was assessing geotechnical risk associated with dual-seam longwall mining in conditions that differed from comparable operations. Uncertainty existed around in-situ stress conditions, pillar sizing, seam [...]

In underground mining studies, success often comes down to finding the right balance between mining method, cut-off grade, cost, and productivity. For our client, that balance was key to unlocking the value of its copper deposit in Queensland. The challenge: identify the most economically viable development path in a field of complex and competing options.

Summary The mining industry is undergoing a fundamental shift. While commodity prices and M&A activity dominate headlines, the real transformation is happening behind the scenes — in mine planning software, artificial intelligence, and digital workflows. These tools are changing how mining projects are: Designed Evaluated Optimised Approved This white paper explores how digital technologies are reshaping three critical areas: Strategic mine planning Technical due diligence Industry-wide digital adoption The key takeaway is simple: Digital tools are not replacing technical expertise — they are amplifying it. For mining companies, the opportunity is to move faster, reduce risk, and make better decisions [...]

Summary Understanding what drives share price movement in ASX-listed mining companies is critical for anyone involved in exploration, project development, or technical advisory. This white paper analyses 259 ASX resource announcements drawn from six AUSTEX Resource Opportunities Reports between October 2025 and March 2026, alongside established academic research and industry frameworks including the Lassonde Curve. The findings challenge common assumptions about market reactions. In short: Not all news moves the market Timing and expectations matter more than outcomes Commodity cycles ultimately dominate company-specific results For technical professionals, the takeaway is clear: markets respond to narrative, anticipation, and macro conditions [...]

Challenge Our client faced the need to rapidly evaluate multiple legacy resource models to determine the feasibility of developing mining operations capable of supporting a set production profile. The technical reports were in Spanish, using legacy block model formats and historical grade estimation methods, creating a barrier for timely assessment. Legacy data formats, proportional rotated sub-blocking, and varying attribute structures meant that careful interpretation was critical. The client also needed cost models to support a Latin American contract mining operation. Approach AI-Assisted Translation & Data Processing: Large technical reports were converted from Spanish to English using AI-assisted workflows, [...]

Introduction Every five years, mine rehabilitation sites must be assessed to confirm they are meeting rehabilitation and PRCP compliance requirements. For this Northern Territory bauxite operation, MEC’s ecology team was engaged to carry out long-term flora rehabilitation monitoring across established sites. These assessments are critical checkpoints — they provide regulators and operators with confidence that rehabilitation is progressing as planned and that long-term environmental commitments are being met. Challenge The work was physically demanding and logistically complex. The team faced: Hot, humid tropical conditions Long field days in remote locations Extremely dense, 40-year-old vegetation In many areas, [...]

Introduction Noise matters, especially when a project sits close to a community. We’re supporting a critical minerals project in Victoria by building a mine schedule that respects noise limits, helping the project move forward while concerns are addressed. Challenge Community backlash around noise levels threatened the project’s ability to proceed. Without local support, approvals would be difficult to secure, regardless of technical merit. Noise modelling showed that limits on equipment numbers and proximity to sensitive receptors, especially during night shifts, would significantly constrain operations. These constraints had direct implications for productivity and project economics. Approach MEC worked alongside [...]

Introduction In the mining industry, clarity and consistency are critical to project success. However, MEC identified a gap in its study processes: the absence of a Checklist and Basis of Design (BoD) framework. Without this framework, reconciling different engineering work often became difficult, and assumptions varied between engineers and disciplines. Challenge MEC needed a standardised BoD checklist to ensure all assumptions were aligned and that every engineering decision was well-documented. This was especially important as the company pursued ISO accreditation for its processes. Approach MEC’s technical team tackled this by developing a comprehensive template for the Checklist and [...]

Introduction Early-stage studies for mining projects often struggle to balance cost, speed, and clarity. For a Queensland gold project with a 32koz defined Mineral Resource, the client needed early direction on whether the asset was worth deeper investment—and they needed it quickly. Challenge After releasing the maiden MRE, the client was trying to answer some big questions: What’s the right development path for the asset? What plant size makes economic sense? How big does the resource need to be to meet internal financial metrics? Traditional concept studies can cost $100k+ and still miss the early directional insights the [...]
