Investigating the reprocessing of Carolin mine tailings
Bibliographic record
Abstract
During the ten year period between Aug 2001 and Aug 2011 the price of gold has experienced an increase of nearly 1500 USD, a jump from 300 USD/oz to close to 1800 USD/oz. This has resulted in a resurgence of interest in gold tailings for what was once below cutoff grade material which is now valuable ore. The tailings at Carolin Mine are the post-processed product from the previous operation which ran from 1982 to 1984 when the average overall gold recovery was 50.2%. This low recovery indicates that a substantial amount of gold-bearing material was sent to the tailings impoundment. This paper describes the history and methodology used in re-evaluating the Carolin mine tailings material as part of a metallurgical feasibility program. [All papers were considered for technical and language appropriateness by the organizing committee.]

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
