Lifecycle Milestones
Jurisdiction (40%)9/10
Ontario: Fraser PPI 2025 is 93.70 of 100 (rank 5 of 68), which maps to 9 on this site's scale. Ontario, Canada (Cobalt / Kirkland Lake area) -- Tier-1 mining jurisdiction.
Infrastructure (40%)No verified figure
Researched with nothing found: no source we could cite confirms or rules out an existing mill, road access, grid power, or tailings facility at Bishop Nipissing Diamond Claims, near Cobalt, Ontario, Canada (checked Oct 2, 2026; recheck due Mar 31, 2027). Counts at a neutral 5/10 until one does.
Nearby producing mine (20%)Not yet researched
No project coordinates on file yet, so distance to a producing mine can't be measured.
Acquisition Susceptibility
A relative ranking of how closely this company matches the profile of juniors that have actually been acquired — not a probability, and not a reason to buy. Acquisitions are rare: only a few dozen significant deals happen a year across a universe of thousands of juniors, so even a high score here describes a long shot. The strongest signal in the research, a producer that already owns part of the company, is scored from its disclosed strategic shareholders. A producer that is a joint-venture or earn-in partner on the project, rather than a shareholder, isn't captured yet.
How this score is built
- Disclosed pending dealSub-score: Not scored
No pending acquisition or merger disclosed (checked)
Not scored: having no deal in flight isn't held against a company.
Weight 26.25% - Producer's strategic stakeSub-score: Not scored
No producer holds a disclosed stake on file (holder register researched) See holders
Not scored: most juniors that do get bought had no prior toehold, so a missing stake says little either way.
Weight 25% - Distance to a producing mineSub-score: Not yet researched
Distance not yet researched: no project coordinates on file
Distance can't be measured without coordinates, so excluded rather than counted as far.
