Forsys Metals says the exploratory ore sorting evaluations at its Norasa Uranium project show that Valencia ore can increase uranium grade and reduce acid consumption during processing.
Ore sorting is a process stage for separating and upgrading run-of-mine ore based on its grade, composition and physical properties.
The key benefits of ore sorting include delivering an upgraded material stream to the processing plant by rejecting waste and problematic lithologies.
The results from ore sorting trials done on Valencia samples indicate that gamma sorting amenability work showed that uranium concentration correlates well with sorting sensor detection peaks.
Furthermore, the sorting test shows that XRF amenability testing demonstrated a substantial calibration accuracy with uranium grades, suggesting that uranium upgrading is achievable with a decrease in mass pull.
The next phase of testwork has commenced for proof of concept for XRF and XRT technologies.
Forsys says given the positive outcome; a decision was made to conduct further confirmatory testwork, which is currently in progress and for which results are expected before the end of Q2 2025.
This work includes detailed XRF testing with machine learning, fine calibration, and scanning of variability samples over approximately 440m of drill core from the Valencia deposit.
Scouting XRT ore sorting amenability testing on variability samples from Valencia deposit.
The results will be used to determine the ongoing testwork and technology appraisal, including economic evaluation.
