Star Metro - Four Nines Gold Intersects 67 Metres at 1.78 g/t Gold, Reinforing Emerging Gold Corridor at Hayden Hill

VANCOUVER, BC / ACCESS Newswire / November 10, 2026 / Four Nines Gold Inc. (CSE:FNAU)(OTCQB:FNAUF)(FWB:F8NA) ("Four Nines" or the "Company") is pleased to announce its best gold intersection to date at the Hayden Hill Project, northern California.

Highlights

Best Gold Grade-Thickness Intersection to Date: HH26-005 returned 67.0 metres averaging 1.78 grams per tonne ("g/t") gold ("Au") and 13 g/t silver ("Ag"), marking continued positive results in the Company's inaugural drill campaign on this low sulphidation epithermal gold system.

• Higher-Grade Gold and Silver Within the Corridor: The intersection includes 35.9 metres averaging 2.30 g/t Au and 15 g/t Ag, with a peak sample of 16.90 g/t Au and 182 g/t Ag over 0.4 metres, highlighting higher-grade precious-metal concentrations within the broader mineralized interval.
• Three Significant Gold Intersections Strengthen the Geological Model: HH26-001 (31.9 metres averaging 1.05 g/t Au, press release October 19,2026), HH26-003 (80.1 metres averaging 1.08 g/t Au ) and HH26-005 have each returned gold-bearing intervals exceeding 30 metres at average grades above 1 g/t Au, all starting at shallow depths (
• Further Drilling: HH26-011, drilled at a steeper angle, encountered approximately 58.9 metres of hydrothermal brecciation comparable to those observed in mineralized holes. Assays are pending.
• Additional Drill Results and Exploration Catalysts Ahead: A total of 12 drill holes have been completed across Hayden Hill, including eight within the LTC, with assays reported from the first three.

Three Significant Gold-Silver Intersections Reinforce the Emerging Lower Telegraph Corridor

The results mark the third significant gold-silver intersection from the Company's first three reported holes targeting the LTC, further strengthening the emerging geological model beneath the historic Lookout Pit. HH26-005 also returned 13 g/t Ag across 67.0 metres, with a peak sample of 182 g/t Ag alongside 16.90 g/t Au over 0.4 metres, demonstrating the presence of both high-grade gold and silver within the mineralized system.

Together, these intersections provide growing evidence of a structurally controlled gold-silver corridor beneath and adjacent to the historic mine. The improvement in gold grade-thickness in HH26-005 is particularly encouraging, providing additional information about the distribution of mineralization as the Company advances toward defining the corridor's dimensions, identifying the geological controls on higher-grade gold deposition and investigating its potential continuation to depth.

Reported intervals are downhole lengths. Further drilling is required to establish true mineralized widths, continuity, geometry and extent.

Management Commentary

Charles Ross, President and CEO of Four Nines Gold, commented:

"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.

"What makes this particularly exciting is how much remains to be investigated. We've now encountered substantial gold mineralization at multiple locations beneath the historic mine, with Hole 005 delivering stronger average grades and adding another important dimension to our understanding of the system. Five additional completed holes in the corridor await assay results and seven other exploration targets remain to be systematically investigated.

"We believe we're only beginning to define what Hayden Hill may host beneath and beyond the areas historically mined. Our objective is to build on these early results and determine the true dimensions and potential of the gold-silver system at Hayden Hill."

Geological Interpretation: Following the Gold System Deeper

The LTC is interpreted as part of a low-sulfidation epithermal gold system, where gold-bearing fluids historically moved upward through fractures and geological structures, depositing gold and silver under favourable conditions. In these systems, mineralization can extend across multiple structures, with higher-grade concentrations developing where the geological conditions were particularly favourable.

HH26-005 provides another important piece of this geological picture. Drilled from the same general location as HH26-003, but approximately 40 degrees apart in direction, both holes encountered similar gold-bearing rock formations characterized by silicification, quartz veining and hydrothermal brecciation. The higher grades in HH26-005, combined with substantial mineralized intervals in both holes, help the geological team to better understand gold distribution within the emerging corridor.

Of particular interest is the system's potential at depth. In epithermal deposits, gold can become concentrated within specific vertical intervals and structural settings, including areas influenced by changes in pressure and fluid boiling. Separate mineralized veins and structures can sometimes converge or coalesce at depth, potentially creating favourable settings for high-grade gold deposition. Previous drilling identified a separate, deeper gold intersection in HH26-003, potentially associated with the historic 214 Vein, providing another important structural clue. The Company continues to investigate potential structural controls at depth as an important part of its ongoing exploration strategy.

Why These Results Matter for Investors

With three significant results from its first three reported holes, Four Nines is building a stronger geological picture of a gold-silver system beneath the historic Lookout Pit. Hole 005's improved grades add important information as exploration advances from confirming mineralization toward investigating the corridor's continuity, structural controls and potential at depth.

Hayden Hill historically produced approximately 480,000 ounces of gold and 1.3 million ounces of silver, but had not undergone systematic exploration drilling since 1997, before the Company's inaugural drill campaign began in 2026. With five additional completed holes in the LTC awaiting assay results, drilling continuing, and seven others currently identified exploration zones yet to be systematically investigated, the Company remains in the early stages of evaluating the property's broader potential.

Hayden Hill Technical Information

Phase 1 Drill Program

To date, twelve (12) core holes (Figure 1) have been completed in 2026 for a total of 1,995.7 metres (6547.6 ft) (Table 1). Hole HH26-013 is in progress.

Most of the 2026 drilling has targeted the Lower Telegraph Corridor (LTC), offsetting from the favorable geology and gold intercept in HH26-001 (press release Oct 1, 2026).

Lower Telegraph Corridor Drill Program

The Lower Telegraph Corridor (LTC), which lies below a portion of the historical Amax Gold open pit, is an extensive zone of multi-phase silicified hydrothermal breccia, silica veins and sulfide veins, identified from surface mapping and drill core.

To date, eight (8) holes (HH26-001, 003, 005, 007, 009, 010, 011, & 012) have been completed specifically to explore the LTC. Assays have been received for three (3): HH26-001, 003 & 005 - each intersected gold mineralization of at least 30 metres length (100ft), at an average gold grade > 1 g/t (Table 2). Another three holes (002, 004 & 008, Figure 1), drilled primarily to explore other mineral zones, have also provided data at the collars to further characterize the LTC.

HH26-005

HH26-005 has been completed to explore the LTC: 1) from the P-850N station (Figure 1), 2) at an azimuth of 289 degrees, inclined at -45 degrees (Figure 2), and 4) to a length of 158.8 metres (521ft) (Table 1).

HH26-005 intersected 67 metres (219.8ft) of precious-metal mineralization at an average grade of 1.78 g/t gold and 13 g/t Ag (Table 2), hosted in pervasively silicified & veined volcaniclastic and multi-stage silicified hydrothermal breccia (Figure 3). The character of the hydrothermal brecciation and veining in HH26-005 is like that of HH26-003.

HH26-011

HH26-011 has been completed: 1) from station P-850N (Figure 1), 2) at an azimuth of 270 degrees, 3) inclined at -70 degrees, and 4) to a length of 176.8 metres (580ft) (Table 1).

The hole intersected the LTC along a length of 14.9 - 73.8 metres (49 - 242 feet), consisting of passive-pervasive silicification, quartz veining overprinting previous pervasive silicification and hydrothermal breccia (Figure 4). This alteration character is comparable to that encountered in HH26-005. The assays for HH26-011 are pending.
