Athena remains a significant shareholder of Mammoth. Mammoth has reported exceptional high-grade silver, gold and critical mineral results from the second phase of reconnaissance channel and rock sampling at the Blue Dick Mine Prospect, with notable high-grade silver assays up to 17,582 g/t Ag (see Mammoth press release dated June 15, 2026).

Highlights from Mammoth – Excelsior Springs Project, Nevada

• Rock and channel sampling of prospective high-grade trends at the Blue Dick Mine Prospect delivered bonanza silver grades, increasing confidence and confirming strike continuity across mineralized trends, with significant new assay results including:

  • 0.20m @ 17,582 g/t Ag, 0.75 g/t Au, 2.76% Cu, 1.72% Sb – MREX00625 – Channel Sample

  • 0.50m @ 3,407 g/t Ag, 0.54% Cu, 0.47% Sb – MREX00621 – Channel Sample

  • 15,336 g/t Ag, 7.46 g/t Au, 2.53% Cu, 0.31% Sb – MREX00718 – Grab Sample

  • 3,945 g/t Ag, 14.4 g/t Au, 0.73% Cu, 0.17% Sb – MREX00721 – Grab Sample

  • 1,760 g/t Ag, 1.98% Cu, 0.32% Sb – MREX00626 – Grab Sample

  • 1,450 g/t Ag, 1.87 g/t Au, 0.22% Sb – MREX00745 – Grab Sample

  • 12.2 g/t Au, 48.9 g/t Ag – MREX00698 – Grab Sample

• Channel sampling of adits and rock exposures across the Blue Dick Mine Prospect has also highlighted critical mineral potential, with significant results including:

  • 3.02m @ 1.61% Cu, 14.3 g/t Ag – MREX00666-669 – Channel Sample

These areas will form key targets for the RC drilling program planned to commence in Q3 2026.
