Great Mining Camps of Canada 1. The History and Geology of the Keno Hill Silver Camp, Yukon Territory
Bibliographic record
Abstract
The Keno Hill Camp was one of The Great Mining Camps of Canada ; it was not only Canada's second largest primary silver producer and one of the richest Ag-Pb-Zn vein deposits ever mined in the world, it was also one of the mainstays of the Yukon economy from the 1920s, after the rapid decline of the Klondike Goldfield, until the early 1960s. At its peak in the 1950s and early 1960s, it supported about 15% of the territorial population. It also produced more wealth than the Klondike, one of the richest placer gold districts in the world. Following a small amount of hand mining between 1913 and 1917, larger scale production was almost continuous from 1919 to 1989, except during the war from 1942 to 1945. Two companies produced most of the ore, Treadwell Yukon Corp. Ltd. from 1925 to 1941, and United Keno Hill Mines Ltd. between 1947 and 1989. Both companies went bankrupt when silver prices failed to increase as quickly as mining costs. About three years of uneconomic 'reserves' remained at closure. SOMMAIRE Le camp minier de Keno Hill est l'un des principaux camps miniers du Canada . Non seulement s'agit-il du deuxieme plus grand producteur canadien de minerai primaire d'argent et l'un des plus riches gisements filoniens de Ag-Pb-Zn exploite du monde, mais il a ete aussi l'un des piliers economiques du Yukon a partir des annees 1920, apres le rapide declin des champs auriferes du Klondike, jusqu'au debut des annees 1960. Au faite de sa production, dans les annees 1950 et debut 1960, il fournissait du travail a environ 15% de la population du Yukon. De plus, il a cree plus de richesse que l'or du Klondike - l'un des plus riches districts d'or placerien au monde. Apres une courte periode d'extraction artisanale, de 1913 a 1917, a suivi une periode d'extraction a plus grande echelle, presque continue, entre 1919 et 1989, sauf durant la guerre, entre 1942 et 1945. Deux societes minieres ont assure l'extraction de la presque totalite du minerai, soit la Treadwell Yukon Corp. Ltd., de 1925 a 1941, et la United Keno Hill Mines Ltd., de 1947 a 1989. Ces deux societes ont failli financierement alors que le prix de l'argent a ete surpasse par les couts d'extraction. A la fermeture, le volume des reserves equivalait a environ trois annees d'exploitation.

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.
