3D Geological Modeling of the Double Eagle – Black Thor Intrusive Complexes, McFaulds Lake Greenstone Belt, Ontario, Canada
Bibliographic record
Abstract
The Ring of Fire region in northwestern Ontario hosts many valuable magmatic ore deposits, including six major chromite and one significant Ni-Cu-(PGE) deposit.A 3D geological model was developed to examine the subsurface architecture and structural disposition of the Double Eagle and Black Thor intrusive complexes that host these deposits.The model is constrained by diamond drillhole datasets, regional geological maps and a refined structural interpretation based on high-resolution magnetic data.Employing implicit and explicit modelling methods, a 3D representation of the intrusive complexes was generated by fitting triangulated surfaces to relevant drillhole constraints.Through the examination of the spatial relationships between the main shear zones and the intrusive units of the DEIC and BTIC, the primary and post-ore deformation geometries of the complexes were evaluated, increasing our understanding of the magmatic plumbing system and supporting the interpretation of a single, connected ultramafic complex dissected and transposed by ductile deformation.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
