Abstract
SummaryThe Sinclair Caesium Deposit, discovered in 2016 by Pioneer Resources Limited, is Australia’s first mining operation to commercially extract the caesium-rich mineral pollucite. Economic caesium deposits are extremely rare, with only three mining operations having produced commercial quantities of pollucite: the Bernic Lake Mine (or Tanco Mine, Manitoba, Canada), the Bikita Mine (Zimbabwe) and now the Sinclair Mine (Western Australia).The formation of pollucite only occurs in extremely differentiated lithium-caesium-tantalum (LCT) pegmatites and given their size and rarity, it can be assumed that caesium-rich deposits globally are either challenging to explore for or form surpassingly rarely during the emplacement of LCT pegmatites.Common with the Bernic Lake and Bikita Deposits, the Sinclair Deposit’s host LCT pegmatite consists of an outer pegmatite wall zone that is coarse grained, and dominated by plagioclase feldspar, muscovite and quartz with other accessory minerals; and an inner core zone composed of quartz, albite (cleavelandite), lepidolite, pollucite, petalite, zinnwaldite, eucryptite, beryl and amblygonite. The core zone is ‘capped’ by a thick (~35-40 m) monomineralic potassium feldspar zone.This paper will present details on the discovery and geology of the Sinclair Caesium Deposit.

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
