Case Study Of Ztem Airborne Tipper Afmag Results Over A Magmatic Nickel Deposit At Forrestania, West Australia
Bibliographic record
Abstract
An airborne AFMAG demonstration survey was conducted over an EM test range that hosts known magmatic copper-nickel occurrences in western Australia, using the ZTEM tipper electromagnetic prospecting system. The test was conducted in late 2009 and was flown to test the system’s capability to detect the highly conductive nickel-bearing massive sulphide bodies in western Australia, below the existing VTEM depth of investigation. The ZTEM results at Forrestania property define both concordant structures related to lithology, as well as discordant lineaments associated with the known ultramafic intrusive center. 2D inversion results define dyke-like conductive features that partly include the known sulphide bodies but extend to greater depth. These results closely resemble those obtained over Eagles Nest magmatic ni-cu deposit in northern Ontario. Foi conduzido um aerolevantamento demonstrativo do tipo AFMAG em uma área testada anteriormente por EM, que apresenta conhecidas ocorrências de cobre e níquel magmático na Austrália Ocidental, utilizando o sistema de prospecção eletromagnético ZTEM tipper. Os vôos foram realizados no final de 2009 para testar a capacidade do sistema em detectar corpos altamente condutores de sulfeto maciço em profundidades abaixo das investigadas no levantamento VTEM pré – existente. Os resultados do aerolevantamento ZTEM na propriedade Forrestania, definiu bem as estruturas concordantes relacionadas com a litologia, assim como os lineamentos discordantes associados com as rochas ultramáficas intrusivas que são bem conhecidos.Os resultados das inversões 2D definiram estruturas condutivas com feições do tipo dique, que em parte incluem os corpos de sulfetos conhecidos, mas que se estendem a grandes profundidades. Esses resultados se assemelham muito com os resultados obtidos no depósito magmático de níquel-cobre no nordeste de Ontário-Canada.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
