Benson Project Background

Situated in the Quesnel Trough, one of Canada's most important mineral belts, the Benson Project is a strategically significant asset that Metalero has the right to acquire in its entirety. 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. At >1,500 km long, the Quesnel Trough runs through the middle of BC stretching from the US to the Yukon Territory. It hosts numerous major mines which produce copper and gold as well as variable amounts of silver and molybdenum while also hosting several types of gold deposits.

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 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.

About Metalero Mining Corp.

Metalero Mining Corp. is a Canadian-based junior exploration company focused on copper and gold projects in North America. Its 173 square kilometer, road-accessible Benson Project serves as Metalero's flagship and is host to five prospects containing gold and copper within porphyry-related mineralized systems.

Toronto, Ontario--(Newsfile Corp. - December 12, 2025) - QcX Gold Corp. (OTC Pink: QCXGF) (FSE: 21MA) ("QcX" or the "Company") is pleased to announce it has entered into mining claim acquisition agreements (the "Agreements") with arm's length parties (the "Vendors") dated December 12, 2025, to acquire 100% of the Olsen Project, a 3,715-hectare land package located within the Batchawana Bay area in northwest Ontario (the "Olsen Project"). The acquisition expands QcX's land position in the Batchawana Greenstone Belt, consolidating a prospective copper-gold district positioned directly along trend of Sterling Metals Corp.'s Soo Copper Project.

The addition of the Olsen Project increases the Company's Batchawana Project to a total of 30 multi-cell claims and 39 single-cell claims, forming a large, mostly contiguous land position that now shares more than 6.6 kilometres of common boundary with the core of Sterling's recently announced discovery (see Figure 1). Sterling's discovery highlights include 262.5 m of 1.05% CuEq (0.52% Cu, 0.005% Mo, 0.49g/t Au, 3.15g/t Ag), with higher-grade intervals including 68.3 m of 3.25% CuEq (1.39% Cu, 0.007% Mo, 1.83 g/t Au, 8.46 g/t Ag) and 9.2* m of 19.8% CuEq (6.8% Cu, 0.008% Mo, 13.2 g/t Au, 46.26 g/t Ag) (Sterling news release dated September 29, 2025). QcX's expanded ground position places the Company prominently within one of Canada's most promising emerging copper districts. The Company cautions investors that mineralization hosted on nearby or adjacent properties is not necessarily indicative of mineralization hosted on the Olsen Project.

Historic work on the Olsen claims indicates five documented mineral occurrences supported by diamond drilling, geological mapping, and geochemical sampling. Historical drilling has intersected quartz-porphyry lithologies, significant pyrite with minor chalcopyrite, and alteration consistent with copper-gold porphyry systems. Historical highlights include a 1.98 g/t Au surface grab sample1 and 0.03% Cu over 1.18 m from historical drilling2.

Strategic and Geological Highlights

• Prime Geological Setting: The Property is located within the Precambrian Batchawana Greenstone Belt and associated metasedimentary sequences along the eastern margin of the Mid-Continent Rift (MCR) - a regional geological setting known for large copper systems both in Ontario and across the border in Michigan.

• On-Trend with Historic Production: The claims lie along strike of the past-producing Tribag Mine, historically mined for copper, molybdenum, silver, and gold.

• Geological Continuity with Sterling's Discovery: QcX's claims display comparable stratigraphy, structural orientation, and magnetic signatures to those hosting Sterling's mineralization. Historical soil geochemical anomalies and untested geophysical conductors provide immediate exploration opportunities.

Upcoming Exploration Work:

QcX intends to commence a target generation & delineation program followed by a prospecting & mapping program across the combined Batachawana Project, following up on the recently completed high-resolution magnetic survey. Desktop studies and fieldwork will prioritize porphyry-style targets, multi-element anomalism, and structural trends.

In addition, the Company will grant the Vendors will be entitled to a 1.5% net smelter returns royalty (the "Royalty") in accordance with the terms of the Agreements. QcX has the option to purchase 0.5% of the Royalty (reducing the Royalty to 1.0%) by making a cash payment to the Vendors in the amount of $500,000.

The completion of the Transaction contemplated by the Agreement remains subject to the approval of all regulatory and other approvals, including the approval of the TSX Venture Exchange. All securities issued pursuant to the Transaction will be subject to a statutory hold period of four months and one day from the issuance thereof, as applicable, in accordance with applicable securities laws.

Qualified Person

Kelly Malcolm, P.Geo. (PGO - 2864), a director of QcX and a non-independent Qualified Person ("QP") as such term is defined by National Instrument 43-101 - Standards of Disclosure for Mineral Projects, has reviewed and approved the geological information reported in this news release. The QP has not completed sufficient work to verify the historic information on the Property, particularly with regards to historical sampling and regional government-mapped geology. However, the QP assumes that sampling and analytical results were completed to industry standard practices. The information provides an indication of the exploration potential of the Property but may not be representative of expected results.

About QcX Gold

QcX Gold is exploring for gold and VMS-style mineralization on its highly prospective and well-located properties in Québec and Ontario. The Golden Giant Project is located in the James Bay region, 2.9 km from Azimut Exploration Inc.'s Patwon discovery on their Elmer gold project. The Fernet Project is located in the Abitibi Greenstone Belt and is contiguous with Wallbridge Mining Company Limited's Fenelon/Martinière property. Both Québec properties are situated near significant discoveries and benefit from favourable infrastructure.

In Ontario, QcX holds the Batchawana Project, a consolidated land position within the Batchawana Greenstone Belt near Sault Ste. Marie. The Project now includes the recently acquired Olsen claims, expanding the property to a contiguous package adjacent to Sterling Metals Corp.'s Soo Copper Project. The area is underlain by greenstone and Mid-Continent Rift-related geology that has historically produced copper, gold, molybdenum, and silver, and remains underexplored with modern techniques.
