Abstract
Given the high stress and poor rock mass conditions found at the Perseverance Mine, appropriate mine engineering and planning techniques are necessary, amongst other mine operational aspects, to perform sustainable mining at current and projected depths. This paper describes the processes and techniques relevant to mine planning and the geotechnical engineering considerations used at Perseverance in the context of deep mining in the Agnew-Wiluna Greenstone Belt. Perseverance Mine produces nickel sulphide ore using sub-level caving and long-hole stoping, and is wholly owned by BHP-Billiton Nickel West. The planning efforts relating to the current sub-level caving operation and the proposed future transition to block caving at a depth in excess of one kilometre are discussed.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
