Abstract

fetched live from OpenAlex

A low‐frequency resistivity survey using ERA electrical profiling (middle gradient array) has been completed over a nickel prospect in Porcupine District, Ontario, Canada. The results of this EM‐Resistivity were used to calculate the apparent resistivity and were further inverted using UBC‐GIF 3D Frequency Domain Inversion Software, EH3DInv. The results of the inversion have shown the anomalous distribution of electrical properties, consistent with a known geological contact between metavolcanic rocks and an ultramafic pluton. The conductive zone has been interpreted to be located in the interval between 70 and 120 meters. The interpreted conductive zone was further subjected for a drilling program. The drilling program was carried out in March–April 2011 and revealed a 21m thick zone with disseminated to massive mineralized intervals starting at 82 meters, which is consistent with the results of 3D inversion of ERA data.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
