Four Nines Gold Inc. (CSE: FNAU) has reported assay results from drill hole HH26-003 at its Hayden Hill Gold Project in Lassen County, California, intersecting 80.1 metres averaging 1.08 g/t gold and 10 g/t silver. The result extends confirmed gold mineralisation 150 metres south of the earlier HH26-001 intercept, reinforcing the company's interpretation of a structurally controlled gold corridor. Investors may be watching closely as the company now designates the target as the Lower Telegraph Corridor, reflecting its broader geological significance.

Key Points

  • Four Nines Gold Inc. (CSE: FNAU, OTCQB: FNAUF, FWB: F8NA)
  • HH26-003 returned 80.1 metres averaging 1.08 g/t Au and 10 g/t Ag, beginning 10 metres below the current pit
  • Gold mineralisation now confirmed at two locations 150 metres apart; HH26-005 intersected approximately 58 metres of similar hydrothermal breccia with assays pending
  • The Lower Telegraph Corridor remains open to the north, south, and at depth, with seven additional exploration zones across the property yet to be tested

HH26-003 Drill Results Define Near-Surface Gold at Hayden Hill

Drill hole HH26-003 was completed to a length of 204.5 metres from the P-850N station at an azimuth of 249 degrees, inclined at -45 degrees. The hole intersected 80.1 metres of precious-metal mineralisation averaging 1.08 g/t gold and 10 g/t silver, hosted within pervasively silicified volcaniclastic rocks and multi-stage hydrothermal breccia. A second, deeper intersection of 8.0 metres averaging 1.10 g/t gold and 15 g/t silver was recorded between 157 and 165 metres, interpreted as a potential down-dip extension of the 214 Vein. The company notes that true thicknesses are not yet known and additional drilling is required.

Lower Telegraph Corridor Takes Shape Across 150-Metre Strike Length

The disclosure states that HH26-001, collared approximately 150 metres north of HH26-003, previously returned 31.9 metres averaging 1.05 g/t gold and 15 g/t silver beginning 6 metres below the pit. Together, these two holes underpin the company's rebranding of the target area from the Lower Telegraph Zone to the Lower Telegraph Corridor, reflecting an interpreted north-south-trending structural system. Six core holes have now targeted the corridor, with assays received for two. The corridor lies directly beneath zones historically mined by Amax Gold and remains open along strike and at depth.

HH26-005 Geological Observations Strengthen Corridor Interpretation

Drill hole HH26-005, completed from the same collar as HH26-003 at a different azimuth, intersected approximately 58 metres of multi-stage silicified hydrothermal breccia between 42 and 100 metres downhole. The release states that the character of brecciation and veining in HH26-005 is very similar to that in HH26-001 and HH26-003. Assays for HH26-005 remain pending. Ten core holes have been completed in 2026 for a total of 1,652.5 metres, with hole HH26-011 in progress. The program represents the first systematic exploration drilling at Hayden Hill since 1997.

Seven Additional Exploration Zones Remain Untested Across the Property

The Lower Telegraph Corridor is the first of eight distinct exploration zones identified through geological mapping and sampling at the Hayden Hill property. The company's 2026 phase-one programme has concentrated drilling resources on the corridor, leaving seven additional zones to be investigated. Three further holes are planned to test corridor depth and southern strike extensions. The Hayden Hill project is a former producing mine with a historical output of 480,000 ounces of gold and 1.3 million ounces of silver. The immediate share price impact was not clear from available public information.
