Metalero Reports Extended Copper and Gold Soil Results at the Cantin Target on the Benson Project, Quesnel Trough, British Columbia.

Exploration Programs

FOR IMMEDIATE RELEASE

Metalero Reports Extended Copper and Gold Soil Results at the Cantin Target on the

Benson Project, Quesnel Trough, British Columbia.

Edmonton, AB, February 12, 2026 – Metalero Mining Corp. (TSXV: MLO) (“Metalero” or the

“Company”) is pleased to announce addi tional results from its recently completed I onic

Leach soil geochemical survey at the Cantin Target, part of the Company’s road accessible

flagship Benson Project, located in the prolific Quesnel Trough of central British Columbia

(Figure 1).

“The results from our 2-week follow-up sampling campaign at Cantin have expanded and

refined our previously defined copper and gold anomalies which cover > 23 km2 (combined)

and remain open in sever al directions. We now see two discrete soil anomalies, each of

which correlate with the QUEST Artificial-Intelligence targets which drew us to Benson in the

first place.” stated Rob L’Heureux, President & CEO of Metalero Mining. “And considering

these Cantin anomalies represent less than 15% of the Benson Project area, we are excited

to explore the other target areas while moving Cantin ahead to our maiden drill campaign.”

Both the copper and gold soil analyses at Cantin show two distinct anomalies overlying the

strong magnetic signature from airborne geophysical surveys. The Cantin Northwest

anomaly (> 8km 2) includes approximately 135 samples which show the anomaly could

extend to the northeast, northwest or southwest directions (Figures 2 and 3 ). The Cantin

Southeast anomaly (> 15km 2) comprises roughly 260 samples and shows the potential to

still be open to the south and northeast.

The two 2025 Ionic Leach programs, conducted in the spring and fall of 2025, were designed

to evaluate and refine copper -gold targets across the underexplored Cantin area, where

historical exploration and recent Geoscience BC Artificial -Intelligence (AI) work has

indicated strong potential for porphyry -style mineralization known as the QUEST targets . A

total of 835 soil samples have been collected at the Cantin, Sundberg, and Chiaz targets

with a 100-metre sample spacing and sample lines 500 to 1,500 metres apart.

major, recent projects and mines all within the Quesnel Trough. Benson is host to known

mineralization associated with porphyry systems which have not been systematically

explored since the early 1990s.

Figure 2. Two discrete copper -in-soil anomalies (yellow outlines) covering >8 km2 (Cantin

Northwest) and >15 km2 (Cantin Southeast) at the Cantin Target, Benson Project. These soil

anomalies are centred on the AI-driven targets identified by Geoscience BC (QUEST), overlap

regional magnetic highs, and remain open in several directions. The 1300 ppb Cu limit

represents the 80th percentile for all Ionic Leach sampling conducted by MLO at Benson to

date (n=835).

Northwest) and > 14km2 (Cantin Southeast) at the Cantin Target, Benson Project. These soil

anomalies are centred on the AI-driven targets identified by Geoscience BC (QUEST), overlap

regional magnetic highs, and remain open in several directions. The 0.71 ppb Au limit

represents the 80th percentile for all Ionic Leach sampling conducted by MLO at Benson to

date (n=835).

Corporate Undertakings

Metalero is pleased to announce a non-brokered private placement which will consist of up

to 3 ,000,000 common shares (the “Shares”) at a price of $0.15 per Share for total gross

proceeds of $ 450,000 (the “Offering”). The net proceeds from the Offering are intended to

fund ongoing exploration and development activities on the Company's mineral properties

and for general working capital purposes. The Offering is subject to regulatory approval,

including that of the TSX Venture Exchange. All securities issued will be subject to a statutory

hold period of four months and one day from the date of issuance.

The Company has granted a total of 2,300,000 incentive stock options to certain officers,

directors and consultants of the Company . Each stock option is exercisable at a price of

$0.15 per common share for a period of five years from the date of grant, subject to the terms

of the Company’s 10% rolling stock option plan and the policies of the TSX Venture

Exchange.

QAQC Procedures

Sample preparation and analysis for the Benson soil survey was completed at the ALS Global

facility in Vancouver , BC. A non-biased 50g nominal soil sample was collected from the

entire field sample without drying or screening. The Ionic Leach method was used to analyze

samples f or 61 elements . This pr ocedur e is defined b y sta tic sodium cyanide leach using

ammonium chloride, citric acid, and EDTA, with the leachant buffered to an alkaline pH of

8.5. A secure chain of custody procedure was maintained in stori ng and transporting

samples.

Benson Project Background

The Benson Project is strategically located in the Quesnel Trough, one of Canada’s most

important mineral belts . The Quesnel Trough is a Triassic/Jurassic -age belt of volcano -

sedimentary and intrusive rocks which hosts >360 alkalic copper-gold porphyry occurrences

and deposits. The >1,500 km long Quesnel Trough runs through the middle of BC stretching

from the US to the Yukon Territory. It hosts several types of gold deposits and numerous

major mines which produce copper and gold as well as variable amounts of silver.

High profile and long-lived mines in the Quesnel Trough include Highland Valley, Mt Milligan,

New Afton , and Kemess which are complemented by recent exploration work including

Woodjam, MPD, Kwanika, and the extensive staking by Australian mining giant, the

Fortescue Group.

The Benson Project lies close to infrastructure and is traversed by Highway 26 and a vast

network of logging roads allowing for ready access to all parts of the Property and capital -

efficient exploration. The large land package covers 5 different target areas i lluminated by

recent Artificial-Intelligence (“AI”) work by Geoscience BC (Mitchinson et al., Geoscience BC

Report 2022-07). This AI study incorporated a wide variety of historical datasets including

geophysics, geology, sampling information, and drilling data (where present) to identify high

potential ( “porphyry-like”) anomalies with similarities to known porphyry deposits

elsewhere in the belt. Even the l imited historical exploration at Benson has identified

numerous gold and copper surface geochemical anomalies while modest , historical drill

programs have intersected skarn and epithermal gold and silver mineralization, which are

both intrusive-related styles of mineralization and are commonly associated with porphyry

systems.
