The mine that almost closed : a review of fifteen years of reclamation at the Kitsault Mine, Alice Arm, British Columbia
Bibliographic record
Abstract
The Kitsault Mine, a molybdenum mine located on the northwest British Columbia coast at the end of Alice Arm, operated intermittently from 1968 until 1982 when low molybdenum prices and market conditions forced its shutdown. The mine operation was under a care and maintenance programme until 1996 when mine reclamation began with the development of a reclamation plan, implementation of mine facilities decommissioning and site preparation for revegetation. Revegetation and water quality goals were also addressed in the plan. The mine was on target to apply for a closure certificate, until redevelopment of the mine was announced in late 2008. This paper presents information on the successful implementation of the reclamation plan, particularly site revegetation, addresses how reclamation planning was used, and reports some of the lessons learned in revegetation efforts in mining.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
