(via TheNewswire)

CALGARY, ALBERTA – TheNewswire - October 21, 2026 – Kairos Gold Inc. (“ Kairos Gold ” or the “ Company ”) (TSXV: KIRO) is pleased to report assay results from the first two holes in the Phase Three exploration program at its Oro Brillante project in Chile.

The Phase Three program was designed to infill and test the Oro Brillante system at depth along the northwest-southeast corridor, with the aim of refining and expanding the mineralized footprint to support a future resource estimate. Phase Three followed the drilling of 10 diamond drill holes- totalling 3,003.8 metres- in Phases One and Two.

The assay results returned multiple gold-bearing intervals, accompanied by elevated silver and copper values, highlighting the polymetallic character of the Oro Brillante system. Collectively, these results provide valuable insight into the distribution of these metals at varying depths and their relationship to the broader geological setting. The Company will integrate these findings with additional technical and geological data generated through its Phase Three drilling program to further refine its understanding of the system.

HIGHLIGHTS FROM OB-26-02:

• 10-metres grading 1.06 g/t Au, 24.20 g/t Ag and 0.01% Cu from 12m to 22m.  

• 7.5-metres grading 0.82 g/t Au, 41.50 g/t Ag and 0.71% Cu from 26.5m to 34m.  

• 14-metres grading 0.94 g/t Au, 3.50 g/t Ag and 0.06% Cu from 109m to 123m.  

• 2-metres grading 5.28 g/t gold, 6 g/t silver and 0.12% copper from 115m to 117m.  

• 20-metres grading 0.96 g/t Au, 12.50 g/t Ag and 0.35% Cu from 135m to 155m.  

• 130.5-metres grading 0.12 g/t Au, 7.30 g/t Ag and 0.43% Cu from 157m to 287.5m, including: 12.6-metres grading 0.16 g/t Au, 22.40 g/t Ag and 1.53% Cu from 242m to 254.6m.  

Oro Brillante, Chile: Assays from Phase Three, Hole 2

The elevated copper values encountered in Hole OB-26-02 represent a particularly encouraging exploration result for Oro Brillante, with a substantial 130.5-metre interval averaging 0.43% Cu, including a higher-grade section of 12.6-metres grading 1.53% Cu. The combination of considerable interval width and elevated copper grades highlights the potential for copper to play a more prominent role within the broader gold-focused system, while providing valuable insight into the nature and evolution of the hydrothermal environment. When considered alongside the lithological, alteration and structural observations gathered from the hole, these findings offer an important opportunity to further evaluate potential metal zonation, geological controls and the extent and continuity of copper mineralization, adding a compelling new dimension to the Company's ongoing exploration program.

Although Hole OB-26-01 did not return any significant assay results warranting inclusion among the Company's principal highlights, the drilling provided important geological information that contributes to the ongoing evaluation of Oro Brillante. The observations gathered from this hole will help establish a more comprehensive understanding of the subsurface geological setting, including variations in rock types, alteration patterns and structural features. The information obtained remains an important component of the broader Phase Three dataset, helping the Company refine its exploration strategy and make more informed decisions regarding future drilling.

Michelle DeCecco, Chief Executive Officer comments: “ We are pleased with the results from our Phase Three program thus far - the assays are delivering the kind of information we set out to gather. One of our key objectives was met in that the alteration across the infill drilling area is consistent with our previous data to support our geological interpretation of the system along its

copper-enriched zone transitioning toward deeper primary mineralization.

On September 25, 2026, approximately 330 samples from Holes 3, 4 and 5 were dispatched to Santiago for analysis. Core logging, cutting and sampling are continuing for Holes 6 through 11, with samples expected to be submitted in batches representing two to three holes. The Company will continue to report assay results as they become available.

All reported interval lengths are downhole lengths. Samples were analyzed by 3A Analytical in Santiago. Gold was analyzed by fire assay, and silver and multi-element analyses were completed by ICP-AES.
