QMines Limited announces successful bulk flotation tests that double processing capacity and boost metal recoveries at its Mount Chalmers and Develin Creek projects. This streamlined plant design is set to cut costs, accelerate development, and unlock significant growth and shareholder value.

QMines Limited has confirmed that its recent bulk flotation test work on a composite ore blend from the Mount Chalmers and Develin Creek projects in Central Queensland delivered exceptional metallurgical results. The tests demonstrate that the company can double its planned mining throughput from 1 million to 2 million tonnes per annum, boosting concentrate production from 190,000 tonnes to an anticipated 482,000 tonnes per annum. These improvements are set to translate into significantly higher annual contained metals of around 14,000 tonnes of copper, 25,000 ounces of gold, 7,500 tonnes of zinc, and 300,000 ounces of silver—all achieved with streamlined processing and simplified plant design aimed at reducing both capital and operating expenditures. The metallurgical results highlight remarkable improvements in metal recoveries, with copper reaching 98.1%, gold 88.7%, zinc 92.6%, and silver 88.6%. The test work supports the viability of a single, bulk flotation circuit that not only cuts back on operating complexity but also offers a faster path to mill construction and quicker cash flow generation. In light of these encouraging results, QMines Limited plans to update its Pre-Feasibility Study to integrate additional deposits from Develin Creek and Mount Mackenzie, thereby extending the mine life and reinforcing the move toward a centralized 2Mtpa processing hub in the region. The company is also evaluating Fluid Bed Roaster and Hydrometallurgical facilities, which could further enhance recovery and deliver valuable by-products such as sulphuric acid and high-purity iron. The announcement marks a strategic turning point as QMines Limited shifts to a regional development model, blending multiple deposits to achieve operational synergies and optimized mine scheduling. The streamlined flowsheet indicates these design improvements may reduce costs related to reagents, energy, and associated processing circuits, while preserving the flexibility to add future capacity enhancements as market conditions evolve. With several catalysts on the horizon – including upcoming drilling results, resource upgrades, and open pit optimizations scheduled for later this year and into the first half of 2026 – the company’s development narrative appears robust and forward-thinking. Analysts are likely to view this development with a bullish sentiment, given the compelling test results, proposed scale-up, and integration of additional ore bodies, all of which could enhance project economics and operational efficiency. The improved recoveries and simpler plant design may lead to accelerated development timelines and lower upfront costs, positioning QMines Limited as a promising mid-tier copper and gold producer. However, a cautious, bearish perspective is warranted due to the inherent risks associated with integrating multiple deposits, potential execution challenges, pending technical assessments, and external market volatility. Investors should therefore weigh the strong technical indicators and strategic initiatives against these uncertainties as part of their long-term evaluation.
