Abstract

fetched live from OpenAlex

Increasing demand for various metals, including gold and silver, has initiated a favorable cycle for mining investors. However, mining projects remain risky due to the significant investments required and project-specific technical factors that are subject to geological uncertainty. Specifically, narrow vein mining suffers from a lack of geometrical freedom in the advance of the excavation; therefore, mine planners must compensate by controlling stockpile and blending and metallurgical process variables. Nonetheless, this lack of geometrical freedom makes it possible to link geological uncertainty to dynamic functioning of the process and ultimately to the net present value and internal rate of return. Discrete rate simulation is an effective approach to dynamic mass balancing, in which geometallurgical relationships can be implemented considering geostatistically variable incoming combinations of andesitic and rhyolitic ore in the case of narrow vein Au-Ag mining. The limited geometrical freedom is conducive to a simple mining sequence, easily implemented within a discrete rate simulation that includes a stochastic representation of the narrow vein orebody based on sequential indicator simulation. The resulting tool uses the apparently disadvantageous geometry of narrow veins and is effective at capturing project-specific metallurgical variables within economic prefeasibility and feasibility studies.

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.
