New Discovery at La Huerta South Sees Grades on Surface Above 10% Copper

NEWS RELEASE

NEW DISCOVERY AT LA HUERTA SOUTH SEES GRADES ON SURFACE ABOVE 10% COPPER

HALIFAX, NOVA SCOTIA – June 19, 2025 – Axo Copper Corp. (TSXV:AXO) ("Axo", “Axo Copper” or the “Company”) is pleased to announce that regional exploration and target generation has yielded high grades on surface, with multiple samples returning greater than 10% copper, in a new discovery ~3km away from the main La Huerta Trend and Las Marias.

“These new high-grade samples at surface provide further evidence driving our thesis that La Huerta could contain multiple high-grade copper structures, beyond the main La Huerta Trend that hosts Las Marias,” said Jonathan Egilo, President and CEO. “Additional work is underway to make this a drill-ready target, and we expect to test La Huerta South with initial drilling in the back end of Q3.”

Surface Grab and Trenching Results

The La Huerta South area represents a region roughly 3km southwest of the Las Marias historical workings and the main La Huerta Trend (see Figure 2). Recent regional exploration work is comprised of mapping, grab sampling, and channel sampling which has resulted in numerous showings of elevated copper grades at surface. Whereas the main La Huerta Trend is characterized by an intrusive dyke with a NE-SW strike orientation, copper mineralization at La Huerta South has been found within N-S faults hosted in andesitic volcanic rocks.

We currently see two broad trends at La Huerta South (see Figure 1). One has an expression that has so far been defined by a N-S strike of ~1,000 metres. This has yielded standout results through samples such as 7.0% Cu at sample LHS-3528, 10.8% Cu at LHS-3494, and 10.5% Cu at LHS-3367, with numerous other showings above 2.0% Cu. Copper mineralization is hosted in chalcopyrite and bornite.

North of the aforementioned N-S fault, lies an antithetic structure with an E-W strike expression that currently extends ~500m along strike. Mineralization is also predominantly chalcopyrite and bornite, hosted within a fault through andesite. Samples in this E-W structure are highlighted by 3.6% at LHS-15808, and 2.6% at LHS-1244.

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 multielement 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.
