Silverband Mine Brake House, Dufton Fell, Milburn, Cumbria: Built Heritage Assessment Report
Bibliographic record
Abstract
Stantec carried out a built heritage assessment of Silverband Mine Brake House, Milburn, Cumbria, England, NGR NY 6949 3070, on behalf of the Natural England Moor House National Nature Reserve (MHNNR) in March 2022. The works were carried out prior to the proposed conservation of the Brake House as part of a Conservation Management Plan being put together by Countryside Consultants of Alston. The Brake House and its associated aerial ropeway were built in 1939 to serve Silverband Mine, a former lead and barytes mine which operated intermittently from at least the 17th century until its final closure in 2006. Both the aerial ropeway and Brake House form part of a Scheduled Monument (NHLE 1021009), and as such are of national importance. The scheduling identifies the site as a rare example of a 20th century aerial ropeway, few of which now survive, and the site is identified as the best surviving example of an aerial ropeway used in a metal-mining context in England. A full Historic England Level 2 survey of the Brake House and aerial ropeway was carried out. The survey identified that, although the ropeway had been damaged by attempts to salvage and remove it when the mine closed in 1964, and the Brake House had suffered through having lost its roof and having partially collapsed, sufficient evidence of its original form and function survived to be able to interpret the structure and provide an understanding of how it had functioned. A complete archive of digital photographs from the survey will be deposited with Archaeological Data Services (ADS). This report and the archive are considered a complete record of the Brake House and aerial ropeway, and no further work is recommended prior to its conservation.

How this classification was reachedexpand
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.
