Four Nines Gold Inc. has reported its best gold intersection to date at the Hayden Hill Gold Project in northern California, with drill hole HH26-005 returning 67.0 metres averaging 1.78 grams per tonne (g/t) gold and 13 g/t silver.
The hole, drilled in the Lower Telegraph Corridor beneath the historic Lookout Pit, also included a higher-grade interval of 35.9 metres at 2.30 g/t gold and 15 g/t silver, with a peak sample of 16.90 g/t gold and 182 g/t silver over 0.4 metres.
Best Hole Yet in the Lower Telegraph Corridor
HH26-005 is the third significant intersection from the first three holes reported in the corridor. HH26-001 returned 31.9 metres at 1.05 g/t gold, and HH26-003 returned 80.1 metres at 1.08 g/t gold. All three intervals exceed 30 metres at grades above 1 g/t gold and start at shallow depths of less than 25 metres beneath the historic pit.
The corridor is interpreted as part of a low-sulphidation epithermal gold system, where gold-bearing fluids moved upward through fractures and deposited gold and silver in silicified hydrothermal breccia, silica veins and sulphide veins. Hole HH26-005 was drilled from the same station as HH26-003 but about 40 degrees apart in direction, and both holes encountered similar gold-bearing rock, helping the geological team map how gold is distributed within the corridor.
“Hole 005 represents another significant step forward at Hayden Hill. Three substantial gold intersections from our first three reported holes in the Lower Telegraph Corridor, with our best gold grade-thickness result yet, delivering 67 metres at 1.78 g/t Au, is an exceptional start to our inaugural drill campaign,”

A Past Producer Being Tested for the First Time Since 1997
Hayden Hill historically produced approximately 480,000 ounces of gold and 1.3 million ounces of silver. It has not seen systematic exploration drilling since the mine closed in 1997. Four Nines holds the right to acquire 100% of the project from a subsidiary of Kinross Gold U.S.A. Inc. Previous operator Amax Gold drilled 99,862 metres in 742 holes at the project before Kinross acquired Amax in 1998.
What’s Next
Twelve core holes totalling 1,995.7 metres have been completed in the 2026 program, with a thirteenth hole in progress. Five additional completed holes in the corridor await assay results, and seven other exploration zones across the property have yet to be systematically investigated. Hole HH26-011, drilled at a steeper angle, cut approximately 58.9 metres of hydrothermal brecciation comparable to that seen in the mineralized holes, with assays pending.
With three of three reported holes hitting broad, shallow gold, investors will be watching the next batch of assays for evidence the corridor holds together — and for signs of higher grades at depth.
