Four Nines Gold Begins Maiden Drill Program at Hayden Hill

Fully funded Phase 1 drill campaign launches the first modern test of the Company's new geological model, targeting high-priority structural gold zones with the flexibility to expand the program based on drilling results and geological observations.

VANCOUVER, BC / ACCESS Newswire / July 21, 2026 / Four Nines Gold Inc. (CSE:FNAU)(OTCQB:FNAUF)(FWB:F8NA) ("Four Nines" or the "Company") is pleased to announce that drilling has commenced at the Hayden Hill Gold Project in Lassen County, California.

LSG Drilling LLC has mobilized to site and begun drilling the first holes of the planned initial 5,000‑foot core program. Drilling will test multiple high‑grade structural corridors and deeper vein extensions identified through the Company's comprehensive 3D geologic modeling. Historical drilling averaged only 150 metres in depth and did not target the high‑grade vein systems now understood to control gold mineralization at Hayden Hill.

Management Comment

"This is the moment our shareholders have been waiting for," said Charles Ross, President & CEO. "Our team has spent months refining the geologic model, permitting drill stations, and preparing for this program. Now the drill is turning, and we are targeting high‑grade zones that have never been tested. The potential to unlock significant value is real and today marks the beginning of that process."

Why this Matters for Investors

• Drilling is now underway on high‑probability targets identified by Four Nines' technical team

• Program designed to test coalescing high‑grade veins at ~200 metres depth, beneath historically mined zones

• Results from this program represent the primary near‑term catalyst for valuation growth

• Demonstrates Four Nines' ability to execute efficiently, with minimal disturbance and strong local support

The Company will provide ongoing updates as the drill program advances, including assay results as they are received, reviewed, and interpreted.

About Four Nines Gold Inc.

Four Nines Gold Inc. is a North American gold exploration company focused on unlocking high-grade potential at past-producing assets. The Company's flagship Hayden Hill Gold Project in northern California produced 480,000 ounces of gold and 1.3 million ounces of silver and has not been drilled in nearly three decades. Leveraging a modern 3D geological model, Four Nines has identified multiple untested high-grade feeder zones beneath and adjacent to historic workings targets missed by previous operators due to shallow drilling and outdated interpretations.

Four Nines is fully funded for its maiden drill program, with 10 approved drill locations and field activities underway as of June 2026. Led by a technical team with a strong discovery record and deep experience in epithermal gold systems, the Company is preparing a high-impact drill campaign designed to evaluate deeper structural corridors and expand the project. Four Nines continues to assess additional opportunities in stable jurisdictions and is committed to responsible exploration, transparent communication, and long-term value creation for shareholders.

Four Nines has a right to acquire 100% of the Hayden Hill Gold Project from a subsidiary of Kinross Gold U.S.A., Inc. The Hayden Hill Gold Project is a former producing gold mine that was explored by Amax Gold Inc. through 99,862 meters of drilling in 742 holes and for which there has been no systematic exploration since the mine closed in 1997. Kinross acquired Amax Gold Inc in 1998. The Hayden Hill Gold Project is located on private land, for which drill permits for the initial exploration program have been received from Lassen County.
