Abstract
Jolliffeite (ideally NiAsSe) and an unnamed mineral [(Co,Ni)AsSe], referred to as "unnamed CoAsSe", are new minerals found in samples from the Shirley Peninsula (Fish Hook Bay area), Lake Athabasca, Saskatchewan. The two new arsenoselenides occur as small discrete anhedral grains, closely associated with clausthalite and unidentified Bi and Pb-Bi-Ag selenides in a pitchblende-rich fracture zone. Jolliffeite is white in plane-polarized reflected light, nearly isotropic, and the reflectance spectrum is flat (e.g., Rr 50.190 at 400 nm to 51.20/0 at 700 nm, in air). It is chemically and crystallographically tJre Se-analogue of gersdorffite-Pa3, with an a of 5.83 I (l) A, and belongs to the pyrite subgroup of Bayliss (1986); D(calc) = 7.10 g/cm3 for Z = 4. The unnamed CoAsSe has similar optical properties to jolliffeite, except that it is slightly more anisotropic. The powder pattgrn could not be indexed; the three strongest lines [d in A (4] are: 2.592(LM),2.365 (80), 1.746(60); the pattern differs from that of synthetic CoAsSe, quenched from 800'C and from 300"C. Neither pattern can be indexed on the orthorhom-bic cell of Nahigian et al. (1974). Jolliffeite honors the late A.W. "Fred " Jolliffe, for his contributions to the commercial exploration of this area of northern Sas-katchewan.

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
