Australian Silica Quartz Group Limited has provided an update on its fully owned metallurgical grade silicon quartz project in far north Queensland. The Quartz Hill Project, located approximately 300km northwest of Townsville, hosts an estimated 17.3 million tonnes of high‐purity quartz averaging 99.04% SiO₂ according to a JORC 2012 compliant resource estimate. The company recently delivered its final Scoping Study in mid-May 2025 to Private Energy Partners’ affiliate, Quinbrook Infrastructure Partners. However, after evaluating the study—examining iron and aluminum levels that exceed updated technical specifications for the intended polysilicon plant—Quinbrook opted not to fund a Feasibility Study, leading to the termination of the existing Heads of Agreement. The technical report outlines key project features including a proposed mining approach using conventional truck and shovel operations, with a planned production capacity of 350,000 tonnes per annum targeted for the off-take. Detailed metallurgical testwork demonstrates that processing techniques, including optical sensor sorting, can generate quartz lump products ranging from yields of 48% to higher grade cuts that show improved silica recovery and lower contaminants. The scope of the study also includes capital expenditure estimates between approximately $2.4 million and $6.8 million, annual operating cost projections of around $27.5 million beyond Year 4, and sensitivity analyses that suggest an attractive base case net present value of roughly $37 million with a very high internal rate of return. Nonetheless, the study emphasizes significant risks such as product recovery consistency, potential need for quartz blending, and uncertainties associated with operating costs and regulatory approvals. Market sentiment from the news presents both encouraging and cautionary elements. On the bullish side, the strong resource grade, positive metallurgical test outcomes, and favorable initial financial projections hint at robust value creation potential if the project’s technical challenges can be addressed and further funding secured. Conversely, the bearish outlook stems from the current inability to meet the full feedstock requirements of Quinbrook’s intended polysilicon manufacturing process, the loss of immediate off-take assurance, and the inherent risks in advancing a new mining project through early-staged, sensitive scoping studies. This mixed picture suggests that while the project’s fundamentals remain promising, prospective investors should remain cautious of the execution risks and ongoing efforts to secure new partnerships or alternative offtake arrangements.
