Metalero Reports Soil and Geophysics Results at the Sundberg Target on the Benson Project,
Quesnel Trough, British Columbia.
Edmonton, AB , March 2 , 2026 – Metalero Mining Corp. (TSXV: MLO) (“Metalero ” or the
“Company”) is pleased to announce results from its recent I onic Leach soil geochemical survey
and geophysics program at the Sundberg target, within its Benson Project, located in the prolific
Quesnel Trough of central British Columbia (Figure 1).
“The Sundberg Target was initially staked to cover a double-lobe QUEST-AI target just 35 km
northwest of Mt Polley, so we are excited to see copper-in-soil anomalies flanking magnetic and
conductivity highs with our first pass of exploration .” stated Rob L ’Heureux, President & CEO of
Metalero Mining , “We are also seeing the benefit of the ground magnetic and VLF -EM
geophysical surveys as they produce high-resolution results relative to the existing historical data
and could be indicating the presence of sulphide minerals at depth.”
The copper-in-soil results at Sundberg show southeast trending anomalies which flank the strong
magnetic signature and some of the conductivity highs from the VLF -EM survey (Very Low
Frequency-Electromagnetics) (Figures 2 and 3). The copper anomalies, with a combined area of
~5 km2, are open in multiple directions and require follow-up exploration work.
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.

have not been systematically explored since the early 1990s.

at the Sundberg Target, Benson Project. These soil anomalies flank the magnetic highs and the AI -driven targets
identified by Geoscience BC (QUEST), remaining open in several directions. The 1,300 ppb Cu limit represents the 80th
percentile for all Ionic Leach sampling conducted by MLO at Benson to date (n=835).

and remain open in several directions . The 1 ,300 ppb Cu limit represents the 80th percentile for all Ionic Leach
sampling conducted by MLO at Benson to date (n=835).
QAQC Procedures
Sample preparation and analysis for the Ben son 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 for 61
elements. This procedure is defined by static 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 storing and transporting samples.
PDAC 2026 Participation
Metalero will be taking part in the upcoming Prospectors & Developers Association of Canada
Conference held at the Metro Toronto Convention Center March 1-4. PDAC has been the World’s
premier mineral and exploration mining convention since 1932, bringing t ogether over 27,000
attendees and 2,500 investors from over 125 countries. This year’s event will feature keynote
speakers such as Gustavo Pimenta, Don Lindsay, Mikko Tepponen, and Paul Bartos.
Interested parties are encouraged to come by booth 2849 to speak to the MLO team.
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. T he
>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 (Figure
1).
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 illuminated 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 limited
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.
