Methodology
Drill scoring
Every drill intercept on OreStocks carries a composite score. This page documents what the score combines and how it is normalized.
What the score is
The OreStocks drill score is a single 0–100 number per intercept — higher is a stronger hit. It combines the headline grade and the intercept length, normalized so intercepts across different commodities — gold, copper, lithium, nickel, uranium, silver, rare earth elements — can be ranked on a relative basis.
What goes into the score
The score combines four ingredients:
- Grade-thickness base — the starting point: grade × length. Grade is in commodity-native units (g/t, %, ppm) and converted to a normalized scale per commodity before multiplying.
- Grade strength — shifts the score for how strong the grade is on its own, independent of the intercept's length.
- Intercept width — shifts the score for how wide the intercept is.
- Intercept depth — shifts the score for how deep the intercept sits downhole, recognizing that near-surface intercepts have different economic implications than deep ones.
The exact weights, curves, and thresholds behind these adjustments are part of the OreStocks scoring pipeline and are intentionally not published. The same inputs are applied to every intercept, and each scored row in the drill terminal shows which of these factors moved its score.
True width vs downhole length
When an issuer reports true width, the score uses true width. When only downhole length is reported, the intercept is flagged as apparent-width-only and the score is computed on downhole length. Investors should discount their width estimate when this flag is set.
Bonanza grades
When an intercept's grade is exceptionally high for its commodity, the row is flagged as a bonanza grade. Bonanza intercepts are held at a minimum score tier — a short intercept length alone cannot push them to the bottom of the ranking — and they are highlighted in the terminal with a badge.
Confidence
Each scored intercept carries a confidence rating: high, medium, or low. Confidence reflects how cleanly the inputs parsed from the source press release. The rating is shown on each row in the drill terminal, and low-confidence intercepts are not given an assessed grade tier.
Source provenance
Every drill intercept is extracted from an issuer press release or regulatory filing (SEDAR, EDGAR, ASX). The original document is linked from each row so the score can be audited against the source.
Updates
The score is recomputed on every new press release. Historical rows are re-scored when the scoring pipeline ships a fix.
Frequently asked questions
- What is the OreStocks drill score?
- A single 0–100 composite number per drill intercept — higher is a stronger hit. It combines the headline grade and the intercept length, normalized so intercepts in different commodities (gold vs. copper vs. lithium) can be ranked on a relative basis.
- Which inputs go into the score?
- The score starts from a grade-thickness base — grade × length, normalized per commodity — and is then adjusted by three qualitative factors: the grade's standalone strength, the intercept's width, and the intercept's depth. The exact weights and thresholds behind these adjustments are part of the OreStocks scoring pipeline and are not published.
- How is the intercept length measured?
- True width when reported by the issuer; otherwise the downhole length is used and the intercept is flagged as apparent-width-only. The provenance is shown on each row in the drill terminal.
- What does a 'bonanza' flag mean?
- An intercept whose grade is exceptionally high for its commodity. Bonanza-flagged intercepts are highlighted with a badge and held at a minimum score tier so a short intercept length alone cannot push them to the bottom of the ranking.
- What confidence levels does OreStocks assign?
- High, medium, or low — based on how cleanly the inputs (grade, length, commodity assignment) parsed from the source press release. Confidence is shown on each row in the drill terminal, and low-confidence intercepts are not given an assessed grade tier.
- Where does the source data come from?
- Every drill intercept is extracted from an issuer press release or regulatory filing (SEDAR, EDGAR, ASX). The original document is linked from each row so the score can be audited against the source.
