Axo Copper Drills 3.1% Copper Equivalent Over 5.8 Metres in First Batch of Phase II Assay Results

HALIFAX, NS / ACCESS Newswire / August 18, 2025 / Axo Copper Corp. (TSXV:AXO) ("Axo", "Axo Copper" or the "Company") is pleased to announce the first batch of assay results from its recently initiated Phase II drill program at the La Huerta Project. The Company is also providing an exploration update on current drilling and visual results, which have seen copper mineralization in deeper drillholes, as Axo has begun stepping out down-dip below Las Marias.

"The first assays of Phase II drilling have produced very strong results as we continue to find, and further define, the La Huerta trend" says Jonathan Egilo, President & CEO. "We are currently drilling some of the deepest holes to date at La Huerta and remain excited about future drilling, as we continue to push the extensions of the mineralization."

La Huerta Assay Results and Exploration Update

Drilling at La Huerta restarted in early June with the initiation of the Phase II drill program. The assay results contained within this release are the first 570 metres of drilling. Approximately 2,100 metres of the 15,000-metre program have been completed thus far, with the focus on a combination of relatively shallow holes stepping out north of Las Marias, covering approximately 300 metres of strike length, in addition to extending mineralization at depth (see cross section in Figure 1).

The Company has received initial assay results, which have been positive in intercepting the La Huerta trend. Results are highlighted by LHCC-25-031 which returned an interval of 3.08% CuEq (2.90% Cu and 14.3gpt Ag) over 5.8 metres, within a broader and wider interval of 1.74% CuEq (1.64% Cu and 7.6gpt Ag) over 12.4 metres. The hole represents a down-dip extension of LHCC-23-021, which was previously reported as 3.16% CuEq (3.00% Cu and 12gpt Ag) over 12.0 metres.

Below LHCC-25-031, the Company recently completed a hole another ~40 metres down dip, LHCC-25-043, as shown in Figure 1. The drillhole intercepted the La Huerta trend, showing a mineralized zone of 10.4 metres with patches of chalcopyrite, of which 3.5 metres contained bornite in addition to the chalcopyrite. Assays for hole LHCC-25-043 are pending.

About Axo

Axo Copper Corp. is a Canadian mineral exploration company engaged in the exploration and development of the La Huerta property, a new copper discovery in Jalisco, Mexico. Initial exploration has yielded high-grade copper both at surface through sampling programs, and at depth through initial drilling. The Company is focused on continuing to define near-surface mineralization along the La Huerta Trend, expanding mineralization at depth, and targeting new discoveries in an underexplored district.

Procedure, Quality Assurance / Quality Control and Data Verification

The diamond drill core (HQ size) is geologically logged, photographed and marked for sampling. When the sample lengths are determined, the full drill core is sawn with a diamond blade drill core saw with one half of the drill core being bagged and tagged for assay. The remaining half portion is returned to the drill core trays for storage and/or for metallurgical test work.

The sealed and tagged drill core sample bags are transported to the ALS Chemex facility in Querétaro and Zacatecas, Mexico. ALS Chemex crushes the samples and prepares 200-300 gram pulp samples with ninety percent passing Tyler 150 mesh (106 μm). Copper and multi-element analysis is completed using total digestion (Code ME-ICP61 Total Digestion ICP). Over limits greater than 10,000 grams per tonne copper are assayed using Cu-OG62.

Quality assurance and quality control ("QA/QC") procedures monitor the chain-of-custody of the samples and includes the systematic insertion and monitoring of appropriate reference materials (certified reference materials, blanks and duplicates) into the sample strings. The results of the assaying of the QA/QC material included in each batch are tracked to ensure the integrity of the assay data. All results stated in this announcement have passed AXO's QA/QC protocols.
