Mammoth Minerals Limited
Mammoth Minerals Limited (formerly Firetail Resources Limited, renamed August 2025; Claremont, WA-headquartered, ASX-listed) is a US-focused gold and critical-minerals explorer. Its flagship is the Excelsior Springs project in Nevada's Walker Lane Trend (a belt that has produced over 40Moz gold), where 2026 drilling at the Buster Gold Trend has returned assays consistent with a Carlin-type deposit model, alongside high-grade sampling at the Imperial Prospect and a maiden drill campaign launched at the Blue Dick target. The company also holds copper/zinc/lithium/silver/lead exploration interests in Australia, Peru and Canada. No resource estimate has yet been published.

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.
1832 Asset Management (Scotiabank's Dynamic Funds arm) holds a real 5.06% stake -- a generalist Canadian manager, not a resource specialist, and on the small side of even that band. Beyond that, no named institutional or strategic holder is on record, and the only other substantial-holder event on file this year was someone leaving the register, not joining it. The company recently divested one project and acquired a historic Nevada gold asset, unrelated to this metric.

Reports, Presentations & Documents
[Description-field-gaps audit batch 3] ouncesFound correctly null: the description's "a belt that has produced over 40Moz gold" is a REGIONAL historic-production statistic for the whole Walker Lane Trend (Nevada/California geological belt spanning ~150 years and many distinct historic mines/companies -- Comstock Lode, Tonopah, Goldfield, etc.), cited only as geological-context color for Mammoth's Excelsior Springs project. Not Mammoth's own resource. No resource estimate has been published for Excelsior Springs (or any Mammoth project), per this row's own description.
