Lifecycle Milestones
Construction Milestones
3 of 5 reachedMilestones are recorded only from a company's own dated disclosure. A milestone with no date shown is one we can confirm was reached but for which no date was disclosed — we don't estimate one. "Not yet reached" means exactly that, not that a date is missing. An "Expected" line likewise only ever reflects the company's own guidance (e.g. a study or permit decision targeted for a stated quarter) — most not-yet-reached milestones have none, and that absence means no such guidance has been disclosed, not that one is overdue.
Not in place: mill. Not yet determined: tailings facility, grid power.
Jurisdiction (40%)5/10
Eskom power-supply reliability and land-reform policy uncertainty in Mpumalanga, South Africa keep this below the top tier; scored 5 like the other Mpumalanga gold miners on this site (the Barberton operations).
Infrastructure (40%)5/10
No confirmed mill and confirmed road access at TGME Gold Project, Pilgrim's Rest Goldfields, Mpumalanga; grid power and tailings facility not yet researched, counted at a neutral 5/10 until established.
Nearby producing mine (20%)Not yet researched
No producing mine within 50 km in our reference list (nearest listed: Booysendal (Northam Platinum Holdings Limited), 52 km). That list doesn't cover every mining district yet, so a longer distance isn't scored as remote.
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

No pending acquisition or merger disclosed (checked)
Not scored: having no deal in flight isn't held against a company.

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.
