HAYDEN HILL SURFACE PROGRAM MAPPED MULTIPLE EPITHERMAL VEINS, HYDROTHERMAL BRECCIAS WITH GOLD VALUES TO 37.9 G/T

Four Nines Gold Inc. has released results for the company's initial surface mapping and sampling program for the Hayden Hill property, located in Lassen county, California. The goal of this phase of the Hayden Hill exploration program is to identify and characterize structural feeders that might host high-grade gold-silver mineralization.

Highlights:

1. The team collected 326 select grab samples, for which results have been received for 140 samples.
2. Highest surface value is 37.9 grams per metric tonne (g/t).
3. Thirteen samples have values greater than 10 g/t.
4. Twenty-two samples have values greater than five g/t.
5. Thirty-four samples have values greater than three g/t.
6. Visible gold (very fine-grained) has been identified at multiple locations.
7. Experienced field explorationists conducted 90 personnel days of surface mapping and sampling during June through August, 2023.
8. Structure, lithology, hydrothermal alteration and sulphide mineralization have been assessed.
9. The mapping has verified multiple mineralized structures indicated by historical workers and identified multiple previously unknown structures. These mineralized structures include banded epithermal veins, hydrothermal breccias, quartz stockworks, zones of pervasive quartz-adularia alteration and oxidized sulphide veins.

David Flint, vice-president, exploration, of Four Nines Gold, said: "We are excited with the results of this initial mapping and sampling program at our flagship Hayden Hill project. Numerous epithermal veins have been mapped and sampled, plus several significant hydrothermal breccia bodies have also been identified. The gold geochemical results are also highly encouraging. Further detailed mapping and sampling is clearly justified. These results verify the concept for which Four Nines signed the exploration agreement with Kinross (April 19, 2023, press release) and are an important step in advancing our understanding of the potential for high-grade gold mineralization to depth at Hayden Hill. The surface data is being utilized to design holes to be drilled from the phase 1 approved drill stations (July 24, 2023, press release)."

Surface program technical results

Summary

The primary goal of this initial field program was to characterize mineralized features that might indicate the presence of epithermal high-grade gold mineralization. Much of the surface of the project area has been disturbed through open-pit mining and reclamation activities. Pit highwalls, historical trenches and pits, undisturbed outcrops, and areas of subcrop have been mapped and sampled.

Structure, lithology, hydrothermal alteration and presence of sulphide mineralization have been assessed at numerous sites throughout the property. The mapping has verified the dominant structural orientation, in three primary zones of the property, as presented in the independent technical report for the Hayden Hill gold-silver project, Lassen county, California, United States (Weiss, 2023, and July 18, 2023, press release). Epithermal quartz veins and breccia bodies are located along these high-angle structures, and are the target for future exploration.

The following styles of hydrothermal features, favourable for the presence of epithermal gold-silver mineralization, have been mapped and sampled on the property:

• Multiple banded epithermal veins;
• Clast-support hydrothermal breccias (clasts comprise greater than 50 per cent of the breccia volume);
• Matrix-supported hydrothermal breccias, for which the hydrothermal matrix comprises greater than 50 per cent of the breccia volume;
• Clasts of previously veined material are common;
• Euhedral adularia and quartz replacement of individual calcite crystals is locally present;
• Pervasive silicification, that is reported to also include fine-grained adularia, is the most widespread form of hydrothermal alteration present in the project area.

An initial set of 326 surface samples have been collected, for which results have been received for 140 samples. Most of the samples are select grabs from structures that appeared to have potential for gold mineralization. The highest sample value is 37.9 g/t. Thirteen samples have values greater than 10 g/t, 22 have values greater than five g/t, 34 have values greater than one g/t, 54 have values greater than 0.5 g/t and 86 have values less than 0.5 g/t. Follow-up sampling for regions with higher-grade initial values is clearly justified.

The surface grab rock chip samples have been analyzed by the ALS Laboratory in Reno, Nev. The samples have been processed according to the following:

1. Preparation: Prep-31 as default, Prep-31BY for samples where visible gold has been observed;
2. Gold assay: Au-AA23 (fire assay with atomic absorption spectroscopy finish); defaults to a second analysis by Au-Grav21 (gravimetric finish) when the concentration from the Au-AA23 assay is greater than 10 parts per million;
3. Certified reference and blank material samples have been inserted into the rock samples submittal at a ratio of one standard/10 rock samples;
4. Chain of custody and security maintained from sample collection through submission to the ALS Laboratory.

The field program has been conducted under the supervision and direction of Mr. Flint, the company's vice-president of exploration. The company's technical advisers and consulting gold exploration experts have also been engaged in the field program.

The following are highlights of the mapping and sampling results for the Property primary mineral zones.

Lookout zone:

• Majority of the Amax Gold historical gold production was from the Lookout Pit.
• Highest gold value of 13.7 g/t.
• Host rocks include a fine-grained volcaniclastic on higher benches, and a dacite breccia in the lower two benches.
• Much of the exposed rock has been pervasively silicified (and assumed be to quartz-adularia) -- phase 1 silicification as described in the technical report (Weiss, 2023).
• North-south-trending epithermal veins (approximately six inches thick) postdate the pervasive silicification.
• Less common northeast- and northwest-trending veins are also present.
• Consistently high gold grades for the grab samples collected above and below the pit ramp (at 679,200 Easting).
• Five permitted drill sites.
• The northern two sites have been designed to target a zone of higher-grade gold mineralization, beneath the current pit bottom, that is indicated by historical drilling.

Providence Nose:

• The Nose is at an approximate elevation of 300 feet (100 metres) above the Lookout Pit bottom.
• Highest gold grade of 23.3 g/t.
• Primary northeast-trending vein set cut by a swarm of northwest-trending veins.
• Hydrothermal breccias developed at the intersection of the two vein sets.
• Euhedral adularia and quartz replacement of calcite identified at several locations.
• The Nose can currently be explored, at depth, from a permitted drill station located at the bottom of the Lookout Pit.

Providence Pit:

• The Providence Pit was a site of modest open-pit historical production by Amax Gold.
• Highest gold value of 37.9 g/t.
• Lithology consists of a fine-grained volcaniclastic, up section, and dacite breccia to depth.
• The Providence veins are primarily oriented to the northeast.
• The northwest-trending Golden Eagle veins intersect the northeast-trending Providence veins within the current pit location.
• Dacite breccia is pervasively silicified for much of the pit exposures.

Golden Eagle zone:

• Most of the Hayden Hill historical underground mine production was from the Golden Eagle northwest-trending veins.
• The current surface above the Golden Eagle veins has been extensively reclaimed.
• The Golden Eagle veins as displayed are from Finn (1987).
• The primary current exposures of the Golden Eagle structural corridor are along the southeast walls of the Providence Pit.
• Amax Gold historical blasthole and exploration drill hole assays provide data to target the Golden Eagle veins to the southeast of the Providence Pit.
