In-sample performance
Gilbert sits in the Walker Lane training region, so these figures measure fit rather than prediction. They are published alongside the held-out districts, and labelled, because the distinction changes what the number means.
- Known deposits in the top 25% of ranked ground 100%
- Known deposits in the top 10% of ranked ground 91%
- Median deposit rank, against all ranked ground top 2.3%
- Peak score in district 0.769
Bars run from 0 to 1. Median rank is shown as the share of ranked ground the median deposit outranks.
Next best measurement
Walk the silicified centre between Mammoth and the Monte Cristo workings, where the anomaly runs continuous across ground carrying no recorded occurrence. Aeromagnetic drone survey, 5 × 5 km AOI, 50 m line spacing, one flying day.
Evidence stack
Every family of evidence enters as its own layer. Read from the bottom up: each layer, then the combined prospectivity surface, then the ranked drill targets and proposed drone survey blocks at the top.
The full brief covers the logic chain, deposit type, nearest known analog, local geology, data density and coordinates.
