Lannister Investor HubComparison guide

Published by Lannister Mining
Ranked by how far each project has advanced, K92 Mining leads, followed by Thesis Gold, Dakota Gold and Lannister Mining.
This comparison of gold exploration companies, published by Lannister Mining, ranks four gold companies by project stage using facts from each company's own website. Lannister Mining places fourth as the earliest stage entry: it has extensive historical drilling at Basin Gulch but has not yet published a resource or economic study.
Question
There is no official list of top gold exploration companies. The right comparison depends on what stage of risk you want. We chose four companies that span the full path from historical drilling to production, so you can see how an early explorer like Lannister Mining differs from a developer or producer. If you want defined reserves or current output, the higher ranked entries fit better. If you want exposure to a first resource in the US, Basin Gulch is the relevant case.
Ranked list
Kainantu Gold Mine, Eastern Highlands, Papua New Guinea
Ranked first because it is the only entry in commercial production, with a Stage 3 plant commissioned in December 2025 and an average head grade of about 10 g/t AuEq since 2018, per its website.
K92 Mining websiteLawyers-Ranch, Toodoggone District, British Columbia (495 km²)
Ranked second because it reports proven and probable reserves and a completed Pre-Feasibility Study, but no production date on its home page.
Thesis Gold and Silver websiteRichmond Hill and Maitland, Homestake District, South Dakota
Ranked third because it has an initial economic assessment and targets production as soon as 2029, with its Pre-Feasibility Study still ahead.
Dakota Gold websiteBasin Gulch, Philipsburg District, Montana (1,107 ha)
Ranked fourth because it is the earliest stage: 320+ historical drill holes and near-surface oxide gold and silver, but no resource or study published yet.

How we chose
Lannister Mining wrote this guide. We ranked entries on one criterion, project stage, measured by three facts taken from each company's own website: whether it is producing, the most advanced economic study published, and whether a resource or reserve is reported. Entries were chosen to show each stage on the path, and two have team links to Lannister Mining as disclosed above. We did not score grade, valuation or exploration upside, and this is not independent research or an audit.
