Star Diamond Corporation
Star Diamond Corporation (TSX: DIAM) holds 100% of the Fort a la Corne diamond properties in central Saskatchewan, including the Star - Orion South Diamond Project -- the largest undeveloped diamond deposit in the world by the company's own characterization -- plus the Buffalo Hills Diamond Project in northern Alberta. Star Diamond is acquiring Rio Tinto Exploration Canada's remaining 75% interest in the Fort a la Corne joint venture. The kimberlites sit near paved highways and the electrical grid, favoring future development economics. A Pre-Feasibility Study is in progress (targeted Q4 2026) building on the July 2024 revised Mineral Resource Estimate.

Lifecycle Milestones
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 the underlying research identifies — whether a major already holds a JV, earn-in, or 5–19.9% strategic stake — isn't tracked yet and is absent from this score.

Insiders, Investors & Smart Money
Notable shareholders and insiders whose involvement is worth knowing about, plus what we're seeing from institutional/large-investor activity.
Two informed owners hold real stakes here. Rio Tinto holds 19.9%, received as consideration for selling its 75% interest in the Fort a la Corne diamond project to Star Diamond in 2024 -- a legacy stake, not a fresh cash bet. Separately, veteran mining financier Jean-Raymond Boulle (founder of Diamond Fields Resources, discoverer of Voisey's Bay) invested $4 million in cash through his Spirit Resources vehicle in August 2025, taking his position to about 25%, and added a further loan in April 2026 that shows he is still adding.
