FOUR NINES GOLD ENGAGES DRILL CONTRACTOR AS HAYDEN HILL ENTERS FIRST MODERN DRILL CAMPAIGN IN NEARLY THREE DECADES

Four Nines Gold Inc. has executed a drilling service agreement with LSG Drilling LLC, a California licensed contractor, marking the operational commencement of the company's fully financed maiden drill program at the Hayden Hill gold project in Lassen county, California. Mobilization is expected to begin immediately, with drilling anticipated to commence on or about July 17, 2026.

This first-phase program includes up to 5,000 feet of core drilling from 10 fully permitted drill stations, targeting high-grade gold mineralization identified through advanced 3-D modelling and structural reinterpretation of historical data. As outlined in the company's July, 2026, investor presentation, historical operators focused on shallow disseminated mineralization, leaving deeper, structurally controlled high-grade zones untested.

Management comment

"We've spent years compiling the data, refining our geological model and building a disciplined exploration strategy," said Charles Ross, president and chief executive officer of Four Nines Gold. "Now, with our drill contractor engaged and a fully funded program ready to begin, it's time to put that thesis to the test. We believe this marks the beginning of an exciting new chapter in Hayden Hill's history."

Why this matters for shareholders

The execution of the drill contract marks the transition from planning to execution at Hayden Hill. With a fully financed phase 1 drill program set to commence, Four Nines is preparing to systematically test the modern geological model that underpins the company's exploration strategy. Backed by a strong treasury, management also retains the flexibility to expand the program beyond the initial 5,000 feet should drilling results and geological data warrant additional follow-up. Management believes this marks the beginning of an exciting new chapter for Hayden Hill as the company undertakes the first modern drill campaign on the project in nearly three decades.

About Four Nines Gold Inc.

Four Nines 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 3-D 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 financed for its maiden drill program, with 10 approved drill locations and field activities under way 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 per cent of the Hayden Hill gold project from a subsidiary of Kinross Gold USA Inc. The Hayden Hill gold project is a former producing gold mine that was explored by Amax Gold Inc. through 99,862 metres of drilling in 742 holes and for which there has been no systematic exploration since the mine closed in 1997. Kinross acquired Amax Gold 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.
