Abstract

fetched live from OpenAlex

This paper employed Random Forests (RF) to generate several Mineral Prospectivity maps for orogenic gold in the Geraldton area, located within the Wabigoon Tectonic subprovince of Ontario, Canada. Various issues pertinent to the Mineral Prospectivity mapping process are presented and proposed solutions to these key challenges are suggested. Additionally, multiple methods are proposed to analyze text-based geoscientific information derived from geological maps, including a novel application of Natural Language Processing (NLP) to delineate the sources and traps of gold mineral systems. The Mineral Prospectivity maps generated have located new possible areas for gold exploration. Concerning the key issues addressed in the paper, (1) the results from NLP have contributed to significant predictor maps for gold exploration, (2) the method for creating a non-deposit class for input to the random forests machine learning algorithm was found to involve creating points at least 2 km from existing Au deposits\occurrences, (3) a weighting method for existing Au deposits based on tonnage produced was successfully introduced and (4) methods of producing ensemble combinations of the Mineral Prospectivity maps were produced and discussed. The results produced from the paper should significantly enhance Au exploration in the Geraldton area of Ontario, Canada.

Teacher imitation

Not 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.
