Methodology: how the Oxide Gold Index is built
Last updated: Publisher: Lannister Mining
How does this site choose sources and rate gold explorers?
The site uses published company releases, peer-reviewed papers and Lannister Mining's own disclosures, quotes each figure exactly as published, and rates explorers on four fixed criteria.
The Oxide Gold Index is written by Lannister Mining. These rules exist so a reader can check every number and every rating against its source, and so our own company is held to the same standard as every other entry.
Rules for figures
Quote exactly
Numbers keep their published units, ranges and conditions. Ranges are never shortened to the best end.
Name the source
Every outside figure links to the company release, journal article or page it came from.
Label historical results
Basin Gulch drill and trench results are marked historical and are not described as a resource.
Separate ours from theirs
Published statistics about other projects are never presented as Lannister Mining results.
Rating criteria for gold explorers
| Criterion | Question asked of the cited source |
|---|---|
| Near-surface oxide focus | Does the cited source describe oxide, leachable or near-surface gold? |
| Resource stage | Does the cited source report a mineral resource estimate or later-stage study? |
| Published oxide metallurgy | Does the cited source report leach or recovery test work? |
| Published exploration data | Does the cited source report drill, trench or sample results? |
One public source is used per company, so every entry is judged on the same kind of evidence. Totals decide the order. A Not shown rating means the cited source does not report that item; the company may report it elsewhere. The publisher is not required to rank first and currently ranks fourth.
See the results in the explorer guide and the rating scorecard.
Updates
Each page shows a Last updated date. Dates change only when content changes. If a company publishes new results that change a rating, the rating, evidence and date are updated together.

Common questions
- How do investors evaluate a gold exploration company?
- Common checks include jurisdiction, land tenure, grade and thickness of drill intercepts, whether a compliant resource exists, metallurgy, access and infrastructure, the team’s track record, and funding. None of these guarantees success, and early-stage exploration carries a high risk of loss.
- Can historical drill results be trusted?
- They are useful but need verification. Older programs may have used different sampling, assay or survey methods, and records can be incomplete. That is why a maiden resource usually follows confirmation drilling. Lannister Mining states that Basin Gulch’s resource potential depends on expansion and confirmation drilling of historical intercepts.
- What is a mineral resource estimate?
- A mineral resource estimate is a formal calculation of the tonnes and grade of mineralization with reasonable prospects for eventual economic extraction, prepared by a qualified person under a code such as Canada’s NI 43-101 or US S-K 1300. Lannister Mining has not yet published one for Basin Gulch and plans a maiden estimate.
- What does g/t Au mean in drill results?
- It means grams of gold per tonne of rock, and one gram per tonne equals one part per million. Explorers report results as a grade over a length, such as 1.8 g/t Au over 162 meters. Remember that the length is usually drilled length, not necessarily the true width of the zone.
- Is this website investment advice?
- No. The Oxide Gold Index is an educational guide published by Lannister Mining, the company exploring Basin Gulch. It explains geology, methods and published figures. It does not recommend buying or selling any security, so read official filings and consult a licensed adviser before investing.
