The company highlighted rubidium as a highly valuable critical mineral with potential to become a primary value driver, noting that its hosting in potassium feldspar could lead to a simpler purification flowsheet. Further work is planned to optimize the flowsheet and develop a maiden rubidium mineral resource estimate. Reasoning: Initial bench-scale metallurgical testwork demonstrated exceptional rubidium extraction rates \(93.8% to 96.7%\) from a cleaner concentrate, indicating a significant new and highly valuable revenue stream for the Faraday Critical Minerals Project. While promising, the results are preliminary and require further development. - Positive factor: High rubidium extraction rates achieved \(93.8% to 96.7%\) - Positive factor: Cleaner concentrate due to rubidium hosted in potassium feldspar, potentially simplifying purification - Positive factor: Significant additional value driver identified for the project - Positive factor: Rubidium is a critical mineral with high market pricing - Positive factor: Potential for valuable byproducts including lithium, potassium, and caesium salts - Positive factor: Multi-domain master composite used for testwork, indicating variability addressed - Negative factor: Testwork is initial bench-scale only, requiring further optimization and scale-up - Negative factor: Purification flowsheet for rubidium salt product still needs development - Negative factor: Rubidium mineral resource estimate is pending Facts used in scoring: 16 ## Classification and evidence **High Recovery** Polarity: positive Definition: Recovery at or above the exceptional band for the commodity and processing route.
