Key findings
- Survival is high. 96% of filers were still listed 5 years after their first report; 88% at 10 years; 33% at 20. Filers still trade in 87% of cases vs. 73% of miners that never filed.
- Value is a different story. Median return since the first filing: −61%. 37% of these stocks are down 95%+ from their all-time high. Only ~3% ever returned 10x.
- What it really measures: a technical report reflects the organizational quality of a company, not the quality of the deposit — structure and market confidence buy time to develop a good project.
Methodology & caveats
- 14,608 filings (SEDAR, 2001–2026) across 3,286 companies, matched by current + historical company names; 926 with a usable monthly price history (Yahoo Finance, ≥12 months).
- Survivorship bias: long-delisted companies rarely appear on Yahoo Finance — real outcomes are likely worse.
- Prices may not adjust for every reverse split. Name matching covers ~37% of filing companies so far — the dataset grows as more profiles are scraped.
