Kairos Gold Completes Phase Three Drilling At Las Garillas And Advances With 3,200-Metre Phase Four Expansion Program

CALGARY, ALBERTA, September 28, 2026 - TheNewswire – Kairos Gold Inc. (“ Kairos Gold ” or the “ Company ”) (TSXV: KIRO) has completed its Phase Three drilling program and will advance to Phase Four, an approximately 3,200-metre expansion program at Oro Brillante located within the Company’s 100%-owned Las Garillas property in the Coquimbo Region of north-central Chile.

HIGHLIGHTS

- Phase Three drilling at Oro Brillante was completed with 11 drill holes;

- Phase Four drilling at Oro Brillante to commence shortly;

- New field operations base established to support exploration activities across the district;

- Planning underway for the inaugural drilling program at the Carmona property.

ORO BRILLANTE PHASE THREE PROGRAM

On June 15 th , 2026, the Company commenced a 10-hole, approximately 3,100-metre drilling program at Oro Brillante, primarily focused on infill drilling to delineate the known mineralized system and support a future resource evaluation. Based on geological observations during drilling, Kairos elected to add an eleventh drill hole to the Phase Three program. Hole OB-26-11 was designed to complete the infill drilling between existing holes on Platform IV and provide further information on the system’s continuity and geometry.

Phase Three drilling was completed on September 26, 2026, and the equipment was demobilized. A restoration team has begun post-drilling activities including reclamation of areas affected by a significant weather event experienced in August. Core logging, cutting, and sampling remain ongoing as the Company integrates information from the Phase Three program with results from earlier drilling campaigns.

The Company’s existing exploration permit authorizes up to 21 drill holes, providing flexibility to expand the drilling program if warranted. Following completion of Phase Three, management is pleased to announce that it will proceed with a Phase Four drilling program, which is expected to commence within approximately 20 days.

ORO BRILLANTE PHASE FOUR PROGRAM

Based on positive core observations from the Phase Three program that indicate open mineralized zones, Kairos is currently preparing for the Phase Four drill program. This program will be focused on expansion drill holes designed to extend known zones and discover new ones. The 10-hole program totalling approximately 3,200 metres is intended to supply information that will be used to support an improved three-dimensional geological model for future targeting and resource calculations. Kairos’ technical team continues to refine the Phase Four drilling program to achieve those objectives.

Michelle DeCecco, CEO & Director of Kairos Gold, commented:

“Phase Four shifts our focus from infill - to expansion. Every single metre that we drill will be important. Upon completion of Phase Four, we expect to have drilled a total of 31 holes and more than 9,500 metres, which will provide us with invaluable geological information to support a future resource estimate.”

“We raised capital to advance exploration, and that is what we are doing. Our strategy is to maintain momentum through back-to-back, disciplined drilling programs. This approach allows our team to incorporate the latest geological observations into our model and systematically advance our projects by expanding known mineralized zones and identifying new ones.”

TECHNICAL REPORTING

The Company continues to await complete assay results for Holes 1 and 2. The laboratory advised that 36 samples returned copper values above 0.5% and require additional analysis using a different analytical method, extending the expected completion timeline.

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. Once received, the assay results will be reviewed and interpreted alongside geological information from Phase Three and earlier drilling campaigns. The Company will report assay results as they become available.

Oro Brillante, Las Garillas, Chile: OB-26-08

NEW FIELD STATION “ESTACIÓN LA HIGUERA”

Kairos has entered into a land-use agreement in the La Higuera de Rapel area and established a field operations base to facilitate exploration activities across the district. The centralized facility will be used for core processing, equipment storage, communications and logistical coordination in support of the Company’s growing exploration programs.

UPCOMING CARMONA DRILLING

Management is actively advancing a drilling program on its Carmona property, located just 7 km from Las Garillas. The maiden drilling program on this attractive opportunity is expected to commence following Phase Four at Oro Brillante. Kairos will provide further updates on its broader Chilean exploration portfolio in subsequent news releases.

Forward-looking information in this news release includes, but is not limited to, statements regarding the timing, scope and objectives of the planned Phase Four drilling program at Oro Brillante; the expected commencement of the program; the interpretation and integration of Phase Three geological information and assay results from Phase Three and earlier campaigns; the timing of laboratory analyses and disclosure of assay results; completion and use of the Estación La Higuera field operations and core-processing base; continued exploration and expansion activities at Oro Brillante; technical, logistical, access and permitting work for the planned Phase One exploration and drilling program at Carmona; the Company’s ability to advance its Chilean exploration projects; and its broader district-scale exploration strategy.

Forward-looking information is based on management’s current expectations, assumptions, estimates and projections as of the date of this news release. These assumptions include that the Company will be able to carry out planned exploration activities substantially as currently contemplated; obtain and maintain required permits, authorizations, surface access and land-use arrangements; engage and retain qualified contractors, personnel and laboratory services; complete drilling, site restoration and core-processing activities on the anticipated timelines; receive and interpret assay results as expected; maintain geological interpretations as additional data becomes available; and have sufficient financial resources to carry out its planned programs.

There can be no assurance that the Company’s exploration programs will result in the discovery or delineation of a mineral resource or that any mineralization identified will ultimately prove to be economically recoverable.
