Abstract
The Geotech Ltd. VTEM heli-time domain EM system entered into commercial service in late 2002 after a development program that started in early 2001. Since then, the system has performed surveys in Canada, the USA, Brazil and southern Africa for a range of mineral deposit styles in a variety of geological settings.The VTEM system bears similarity to many of the past and currently operating heli-time domain system designs but has focused more than other developments on operational simplicity and flexibility in how the system is configured. A very high dipole (coupled with very low system noise levels) is deemed a major differentiating factor of the system compared with others in current operation.In terms of applications, VTEM is seen as an effective bridge between existing airborne electromagnetics technologies, combining the high spatial resolution associated with helicopter systems but with a depth of investigation similar to what fixed wing time domain systems were traditionally required to achieve.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
