6 terms

diamond drilling technical

"Strong initial results from Mammoth's maiden diamond drilling program at Excelsior"

Diamond drilling is a method that uses a rotating drill with industrial diamonds on the bit to cut and retrieve cylindrical rock samples (cores) that preserve the sequence of underground layers. For investors, these cores act like a geological “biopsy,” providing direct, verifiable information about mineral presence, grade and continuity—data that underpins resource estimates, project valuation, drilling risk and financing decisions.

intrusive complex technical

"The survey defined a large, 5.5 km x 4.2 km interpreted intrusive complex"

An intrusive complex is a cluster of unwanted, recurring thoughts, memories or feelings that surface involuntarily and cause distress, similar to a broken record replaying upsetting material in the mind. For investors, it's relevant because such symptoms drive demand for therapies, influence how clinical trials are designed and measured, and can affect regulatory scrutiny and market size for drugs, digital treatments or diagnostic tools addressing mental-health conditions.

skarn-type technical

"Multiple skarn-type targets identified within and proximal to the intrusive complex."

Skarn-type describes a kind of mineral deposit formed where hot molten rock forces its way into limestone or other carbonate rocks, causing chemical changes that concentrate metals such as copper, iron, zinc or gold. For investors, identifying a skarn-type deposit signals a potential for high-grade, localized mineralization — like finding a dense nugget in a field — which can mean higher value per ton but also a specific set of exploration, mining and processing challenges.

high-resolution magnetic survey technical

"A high-resolution magnetic survey (40m line spacing) was conducted over the Excelsior Springs Project"

A high-resolution magnetic survey is a detailed measurement of tiny variations in the Earth’s magnetic field taken over a target area to map differences in underground rock types and structures. Think of it like using a very sensitive metal detector to reveal where different materials lie beneath the surface; for investors it helps companies find likely mineral or ore bodies, prioritize drilling targets, reduce exploration risk, and refine project value estimates and timelines.

Mineral Resource Estimate technical

"Work has now commenced on an initial Mineral Resource Estimate and Exploration Target."

A mineral resource estimate is a calculated approximation of how much metal or mineral material likely exists in a particular deposit and where it sits underground, similar to estimating how many cookies are in a jar by peeking at the layers. It matters to investors because it provides a data-based starting point for judging a project's potential value, future production and risks, while not guaranteeing recoverable or profitable amounts.

NI 43-101 regulatory

"as defined by NI 43-101 "Standards of Disclosure for Mineral Projects"."

A Canadian regulatory standard that sets the rules for how mining and exploration companies must report mineral resources and reserves, requiring technical reports prepared or signed off by an independent, certified expert. It matters to investors because it creates a consistent, transparent “inspection report” for mining projects, making it easier to compare prospects, judge the reliability of claims, and assess geological and financial risk before investing.

Maiden diamond drilling returns 4.33 g/t Au over 14.4m; geophysics defines large intrusive

WHITE ROCK, BC / ACCESS Newswire / November 26, 2025 / Athena Gold Corporation (CSE:ATHA)(OTCQB:AHNRF) ("Athena" or the "Company") is pleased to provide an exploration update from its Excelsior Springs Project in Nevada. Mammoth Minerals Limited (ASX:M79) (formerly Firetail Resources Limited) has been aggressively exploring Excelsior, per its option agreement to earn an 80% interest in the project over five years, providing Athena a free-carry to Definitive Feasibility Study thereafter (see press releases dated June 2, 2025, and August 22, 2025). Recently, Mammoth reported two significant announcements from its ongoing exploration campaign (refer to Mammoth Minerals press releases dated November 24, 2025, and November 26, 2025). As of today, Athena remains a significant (>5%) shareholder of Mammoth Minerals Limited.

Key Highlights from Recent Mammoth Diamond Drilling (Buster Trend)

• Strong initial results from Mammoth's maiden diamond drilling program at Excelsior, with multiple shallow high-grade gold intercepts in the first three diamond holes at the Buster Mine Trend, validating and extending the geological model:

  • 14.4m @ 4.33 g/t Au from 117m (MEXDD004), including:

    • 3.1m @ 19.10 g/t Au from 119.36m; and

    • 0.95m @ 15.98 g/t Au from 124.5m

  • 25.5m @ 1.05 g/t Au from 35.45m (MEXDD001), including:

    • 0.55m @ 26.7 g/t Au.

• These intercepts successfully tested 50m down-dip extensions and infill areas around the historic Buster Underground Mine (past production 19 koz @ 41 g/t Au) and validate Mammoth's targeting model developed from 14.5 km of historical drilling.

• Mineralisation remains open at depth and along strike; diamond drilling has thus far targeted ~1.1 km of the >5 km Buster Trend strike, with mineralization confirmed to 250m depth.

• Work has now commenced on an initial Mineral Resource Estimate and Exploration Target.

• Nine additional diamond holes totaling 1.3 km drilled have assays pending targeting down-dip extensions beneath the Buster Underground and the ~350m-long by ~25m-wide Buster Open Pit.

Key Highlights from High-Resolution Airborne Magnetics (Project-Wide)

• A high-resolution magnetic survey (40m line spacing) was conducted over the Excelsior Springs Project, including the additional claims recently staked by Mammoth.

• Per Athena's press release dated November 11, 2025, portions of this newly staked ground fall within the project's 5 km Area of Interest ("AOI") buffer around the existing Excelsior claims, automatically incorporating them into the joint venture ("JV") upon Mammoth's earn-in.

• The survey defined a large, 5.5 km x 4.2 km interpreted intrusive complex and associated caldera north of the Buster Trend.

• The feature exhibits strong geological and structural similarities to the 4.2 Moz Goldfield Caldera located 35 km to the north-east.

• High concentrations of historic workings, shafts, pits and costeans occur along the margins of the intrusion; Mammoth has collected 350 rock-chip samples from these old workings with assays pending.

• Multiple skarn-type targets identified within and proximal to the intrusive complex.

• Preliminary structural interpretation has extended the prospective Buster Trend geological strike to 7.3 km.
