Developing a Multi-Project Copper & Gold Production Hub in Queensland, Australia.
QMines (ASX:QML) is consolidating three Queensland copper and gold projects, Mt Chalmers, Develin Creek and Mt Mackenzie, into a single Multi-Project Copper & Gold Production Hub across one Central Queensland district. Since listing on the ASX in May 2021, the company has grown the resource base through nine JORC resource announcements, and Mt Chalmers is now advancing through a fully funded Definitive Feasibility Study toward a development decision.
Mt Chalmers is a high-grade historic copper-gold-silver deposit located 17km northeast of Rockhampton.
It hosts a defined Ore Reserve of 9.6Mt and is the cornerstone of QMines’ proposed central processing hub. With shallow mineralisation, established infrastructure, and strong metallurgy, Mt Chalmers offers a low-strip, high-margin development opportunity and remains open along strike and at depth.
Develin Creek is a copper-zinc project situated approximately 90km northwest of Rockhampton and 45km southeast of Mount Mackenzie.
It hosts multiple Volcanic Massive Sulphide (VMS) deposits, including Sulphide City and Scorpion, with near-surface mineralisation and recent resource growth.
Ongoing drilling is targeting extensions and conversion of Inferred resources, with strong potential for integration into the Mt Chalmers processing flowsheet.

Mount Mackenzie is a gold and silver project located around 140km northwest of Rockhampton. The deposit contains 5.2Mt @ 1.01g/t Au and 6.7g/t Ag, with mineralisation at shallow depths and strong development potential.
With room for resource expansion and compatibility with regional processing infrastructure, Mount Mackenzie strengthens QMines’ multi-commodity strategy and adds precious metals exposure to the portfolio.
Key facts
Resource growth is the backbone of what QMines has built: nine JORC resource announcements across its Queensland portfolio, lifting the resource base at each project along the way.
Mt Chalmers is fully funded through to a Definitive Feasibility Study and approvals, backed by a $15 million investment from the Queensland Investment Corporation. Key consultants are appointed and baseline studies are underway, alongside continued consolidation of QMines’ landholding across the district.

QMines’ longer-term vision is a centralised processing plant servicing several regional mines, producing an estimated 20-30 kilotonnes per annum of copper equivalent for more than ten years. QMines holds ten known deposits, nine of them outside the current Mt Chalmers mine plan, representing significant potential still to unlock. Mt Chalmers itself is targeting production and cashflow within the next few years.
QMines has consolidated three Queensland copper and gold projects into a single district-scale portfolio, growing the combined resource base at each step and advancing Mt Chalmers toward a development decision through a fully funded DFS. The bigger opportunity is the vision beyond it: a centralised processing hub drawing on a wider district still to unlock.
QMines holds three Queensland copper and gold projects, all within the same Central Queensland district near Rockhampton: Mt Chalmers, Develin Creek and Mt Mackenzie.
It is QMines' vision for consolidating its three Queensland projects around a centralised processing plant that could service several regional mines, producing 20-30ktpa of copper equivalent for more than ten years.
Mt Chalmers is the most advanced of the three. It is the only project with a declared Ore Reserve (9.6Mt Proved and Probable), has completed a Pre-Feasibility Study confirming a 10.4-year mine life, and is now progressing through a fully funded Definitive Feasibility Study, targeting production and cashflow within the next few years.
Each project carries its own independently defined JORC resource. QMines' longer-term thesis links them operationally, trucking ore from Develin Creek to a centralised Mt Chalmers processing facility, with Mt Mackenzie contributing further mineralisation to the same hub.
