Ann: Mumbezhi Testwork Returns Excellent Flotation Results, page-3

ChatGPT response to the question "Interpret these results as good, very good or excellent":

These metallurgical test results can be interpreted as excellent, based on industry norms and typical expectations for early-stage copper projects. Here's why:
1. Copper Concentrate Grades and Recoveries24.6% Cu at 96.2% recovery after a single cleaning stage is exceptional. This shows that the ore responds very well to flotation, yielding a highly saleable product with minimal processing.33.3% Cu at 90.1% recovery after two cleaning stages is also excellent, offering a very high-grade concentrate, though with slightly reduced recovery—still above industry thresholds.
2. Coarse Grind Feasibility (up to 250 µm)Being able to coarsen the grind size without losing significant recovery is very positive. This means potential lower energy costs and cheaper plant design, improving project economics.
3. Graphitic Carbon ToleranceHigh graphitic carbon (up to 4.8% TGC) often interferes with flotation, but in this case, it does not, which is a very good outcome and reduces risk.

4. Comparable Flowsheet to Other Zambian OperationsUsing a proven, simple flowsheet reduces technical risk and eases scalability—another excellent sign.

Summary Interpretation:The overall results are excellent, with high recoveries, strong concentrate grades, low processing complexity, and positive cost implications. These results strongly support the potential economic viability of the Mumbezhi Copper Project.
