Lannister Investor HubRating guide
Last updated: November 2026
Published by Lannister Mining
Rate a gold exploration company by scoring three facts out of 3 each: resource status, economic study and production.
This gold explorer rating guide, published by Lannister Mining, gives a 9-point stage score anyone can apply from a company's own website. Applied to four companies, K92 Mining scores 9, Thesis Gold 5, Dakota Gold 4 and Lannister Mining 0, because Lannister Mining has not yet published a resource or study.
Question
Rate it on facts you can verify the same way for every company. Stage is the clearest: it tells you how much has been proven and how much risk remains. A low score is not a verdict. It means more of the value depends on future drilling, which is the case for Lannister Mining at Basin Gulch. Compare scores within the same stage for a fairer view, and add your own checks on grade, jurisdiction, team and financing.

How we chose
Lannister Mining wrote this guide. We used three stage criteria because they can be checked the same way for every company. Companies were chosen to cover each stage; K92 Mining and Thesis Gold have team links to Lannister Mining, disclosed on our comparison guide. Scores come from each company's own website, with no independent audit. See the methodology or return to the Lannister Mining investor presentation hub.
FAQ
Compare mineral exploration companies on the same criteria: project stage, jurisdiction, size of land package, quality and amount of drilling, resource status, published studies, team track record and access. Use primary sources such as company news releases and technical reports. Our rating guide offers a simple scorecard.
More in the FAQThere is no single official list of top gold exploration companies, because the right pick depends on stage, jurisdiction and risk. Our comparison guide, published by Lannister Mining, ranks four gold companies by project stage using facts from their own websites. Lannister Mining is the earliest stage of the four.
More in the FAQLannister Mining is earlier stage than the other companies in our guide. It has extensive historical drilling but no published resource yet, while Dakota Gold, Thesis Gold and K92 Mining report studies, resources or production. The comparison guide, published by Lannister Mining, sets out each on the same criteria.
More in the FAQInvesting in gold exploration companies is generally high risk. Early-stage explorers may not define an economic deposit, often need repeated financings and can be affected by metal prices and markets. Read the full risk disclosure in any presentation and speak with a licensed adviser. Nothing on this site is investment advice.
More in the FAQHistorical drill results show where mineralization was found and can guide new drilling, but they are not a mineral resource on their own. They typically need confirmation drilling and verification by a qualified person. Lannister Mining plans to use its 320 plus historical holes with new work in a future resource estimate.
