Vault Strategic Mining Corp.
Vault Strategic Mining Corp. (formerly Margaret Lake Diamonds Inc., renamed December 2025) acquires and advances critical-mineral projects in top-tier jurisdictions, currently focused on tungsten. Its War Bond Tungsten Project in Nevada encompasses the historical War Bond, Tactite and Thursday tungsten mines; an August 2026 UAV magnetic survey (70km) followed assay results of up to 1,100 ppm tungsten and 4,430 ppm manganese. The company also holds the Gray Eagle Project in the Bishop Mining District, Inyo County, California, including the historical Mirage-Mariposa Tungsten Mine, where a maiden exploration program has been engaged via Rangefront Mining Services. The same May 2026 definitive mineral property purchase agreement that added Mirage-Mariposa/Gray Eagle also included the North Tungsten Project in Nunavik, Quebec. No NI 43-101 resource estimate has been published for any property; in July 2026 the company engaged Amazona to prepare a maiden NI 43-101 technical report on War Bond, and on 29 Sep 2026 it closed a $1,500,000 private placement.

Lifecycle Milestones
Jurisdiction (40%)9/10
Nevada: Fraser PPI 2025 is 100.00 of 100 (rank 1 of 68), which maps to 9 on this site's scale. The rating follows the War Bond tungsten project in Douglas County, western Nevada, the project its corporate presentation leads with and the focus of its 2026 field work. Its Letain nickel project in British Columbia is also in a highly rated 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 War Bond Tungsten Project (option), Delaware Mining District, Douglas County, Nevada, USA (checked Oct 5, 2026; recheck due Apr 3, 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.
