Part 2 – How Polymetalic Systems Form and Why Minbrie May Be Unique

Gold and silver don’t show up alone when multiple metals appear together, nature is sending a signal: this is a system, not a coincidence. When copper, lead, zinc, silver and gold appear in the same geological structure, it’s not random luck. It’s a sign that a polymetallic system is forming a deep and complex mineral network created by millions of years of intense geological processes. These systems usually form through hydrothermal mineralisation. In the distant past, during volcanic or magmatic activity, hot fluids rich in dissolved metals were pushed up from depth. These fluids moved through fractures and layers in the surrounding rock, and as pressure and temperature changed, metals began to deposit in organised zones and sequences. Depending on depth, temperature, and host rock chemistry, different minerals formed chalcopyrite and bornite for copper, galena for lead, sphalerite for zinc, with barite, pyrite, and quartz commonly present as gangue minerals. Silver and gold often appear later or alongside sulphides, while trace elements like germanium, antimony, bismuth, indium, tellurium, and cobalt can emerge under the right conditions. When all of these elements are found together, it’s strong evidence of a long-lived, evolving hydrothermal system. Nature doesn’t combine these metals unless the geological plumbing is both complex and powerful. Australia has only a few well-known, highly productive polymetallic systems Rosebery in Tasmania and Golden Grove in Western Australia are examples that delivered millions of tonnes of ore and attracted billions in investment. Minbrie is now showing similar signs. It sits in a volcanic-sedimentary region and is already returning multiple metals in early drillholes. The presence of copper, lead, zinc, silver and gold in the same horizon strongly suggests this is a genuine multi-element system. In addition, Minbrie is located in a mining-friendly area, close to rail infrastructure and supported by state incentives and research grants. This combination of geology and location is both rare and valuable. If the system evolves further as models suggest, future drilling could reveal clear metal zoning, oxidised surface zones with cobalt, deeper vein structures rich in gold and silver, and additional strategic elements like germanium, indium, tellurium and bismuth. Systems like this are rare because they require a precise mix of conditions volcanic activity at the right geological moment, a network of structural fractures, metal-rich fluids, reactive host rocks, a stable pressure-temperature environment, and preservation through time. Not many places on Earth offer all of that and even fewer remain unexplored. Minbrie is not just another drill target. It may be the discovery of a multi-metallic system with long-term strategic value. As the global economy shifts toward electrification, renewable energy, and advanced infrastructure, demand for these metals continues to grow. The geology here indicates the system is real. If confirmed through further modelling and drilling, the potential value could be significant. I will continue trying to educate as many people as possible about systems like this without quoting percentages or provoking arguments because I believe knowledge should be shared, not used to divide. When people understand how these systems truly form, they will better appreciate what we may be uncovering here. Part 3 coming tomorrow how we value systems like this, from geology to economics. It’s time to understand the full picture and focus on learning together rather than attacking each other. Once fresh and confirmed numbers arrive in few weeks, we can then discuss what they mean in dollar terms. Until then, let’s keep building understanding and avoid wasting energy on outdated 15-year-old PDF files and legacy JORC models that no longer apply except as historical guides pointing toward smarter, more precise drilling needed to build the next generation of valuable JORC resources.
