UPDATING MANITOBA'S PRECAMBRIAN DRILL CORE LIBRARIES INVENTORY
Bibliographic record
Abstract
primarily from exploration drilling, since the early 1970s. Since that time, the Manitoba government has managed to create a substantial repository of drill core at five locations throughout the province. From 1984 to 1989, the Canada–Manitoba Mineral Development Agreement provided substantial funding to expand Manitoba’s core library facilities. Since the early 1990s, the core libraries have been run on a care-and-maintenance basis. However, exploration companies continued to deliver drill core to various libraries on a sporadic basis. Due to the lack of funding, core library inventories have not been kept up to date. In 2001, funding became available to better organize recent drill core additions and to update all core library inventories. Drill core stored at the Centennial compound near Flin Flon was reorganized and inventoried for the first time. The depart-ment is also creating a new database of all drill core holdings within the province’s libraries. INTRODUCTION AND HISTORY The Manitoba Mineral Resources Division considered the archiving of exploration drill core to be a valuable data source that can be utilized by explorationists and researchers. For this reason, the province has retrieved and stored Precambrian drill core since the early 1970s. The construction of core sheds at The Pas (1972), Thompson (1973) and Lynn Lake (1974) provided storage space that enabled a concerted effort toward core collection.

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.
