Lifecycle Milestones
Combined view across 2 projects. Figures below are only combined where the underlying basis genuinely matches -- see the notes under each.
Jurisdiction (40%)8/10
Montana: Fraser PPI 2025 is 69.00 of 100 (rank 40 of 68), which maps to 8 on this site's scale. Montana, USA — a strong US 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 Columbia Gold-Silver Project, Montana (checked Oct 1, 2026; recheck due Mar 30, 2027). Counts at a neutral 5/10 until one does.
Nearby producing mine (20%)Not yet researched
No producing mine within 50 km in our reference list (nearest listed: Continental (Butte) (Montana Resources, LLP), 104 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.

Insiders, Investors & Smart Money
Notable shareholders and insiders whose involvement is worth knowing about, plus what we're seeing from institutional/large-investor activity.
Capricorn Metals, a real operating Australian gold producer, both sold Sentinel its new Big Springs project in Nevada and put cash into both the July and August 2026 placements; it now holds 9.91% (13,793,104 shares, its 28 August 2026 substantial-holder notice) -- a real producer stake, though tied to the vendor relationship. Jody Dahrouge's DG Resource Management group holds 20.98% (its 31 August 2026 notice); Sentinel's annual report does not attribute that block to director Simon Dahrouge. A broader Australian fund manager, Perennial, also holds a stake, though it does not appear to specialise in resources specifically.

Reports, Presentations & Documents
Sentinel Metals is a gold explorer with two US projects: the Columbia gold-silver project in Montana's Blackfoot Valley and the Big Springs gold project in Nevada, whose acquisition from Capricorn Metals it completed on 26 August 2026 after shareholder approval on 20 August. Columbia's JORC resource is entirely inferred, 21.4 Mt at 1.3 g/t gold and 4.6 g/t silver for 920,000 oz of gold and 3.14 Moz of silver, and Sentinel began its first diamond drilling there in June 2026, a program of about 5,000m in 21 holes. Big Springs is a permitted, past-producing project, with historical output of about 386,000 oz at 4.1 g/t from seven open pits, and carries a JORC resource of 15.5 Mt at 2.0 g/t gold for 1.01 Moz: 0.86 Mt at 4.7 g/t measured (129,000 oz), 6.00 Mt at 2.2 g/t indicated (426,000 oz) and 8.63 Mt at 1.7 g/t inferred (459,000 oz). The total consideration of up to about A$26M includes US$8.5M in cash and 8,620,690 shares, and Sentinel now describes a combined gold platform of about 2 Moz across the two projects.
