Rating guide
Last updated: November 2026 · Published by Lannister Mining
This scorecard rates five gold companies on development stage, from 1 for exploration to 4 for production, and checks which hard numbers each has published. Published by Lannister Mining, it rates Coeur Mining, K92 Mining and West Red Lake Gold 4, Thesis Gold 2, and Lannister Mining 1.
Start with stage, because it sets the type of evidence you can expect. A producer reports ounces and revenue; an explorer reports drill holes and intercepts. Then check what each company has actually published. A low stage rating is not a bad score: it means the company is earlier, with more risk and more room for discovery.
