Geology of the 1901 deposit and implications for controls on Cu–Zn–Au VMS mineralization in the Chisel Sequence, Snow Lake arc assemblage, Snow Lake, Manitoba, Canada
Bibliographic record
Abstract
The 1901 deposit of Hudbay Minerals Inc. is one of seven Zn−Cu–Au volcanogenic massive sulfide (VMS) deposits in the Lower Chisel Sequence at Snow Lake. Past research suggests that VMS mineralization in the Chisel Lake area occurs at a conformable stratigraphic boundary between the Lower and Upper Chisel sequences (LU–UC). However, our investigation indicates that mineralization occurs below this contact, in a calc-alkaline volcanic sequence, with the LC–UC contact being a flat-lying, shallow northeast-dipping fault, known as the Chisel–Lalor Thrust Fault (CLTF). The CLTF is found at the Chisel North and Lalor Lake VMS deposits, where there are distinct angular differences between the barren rocks above the fault and the mineralized zones below. Faults like the CLTF are difficult to detect in volcanic domains, but crucial for exploration models as they can disrupt and repeat favourable formations and obscure stratigraphy.

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.
