Vancouver, British Columbia--(Newsfile Corp. - November 21, 2025) - MAX RESOURCE CORP.  (OTC Pink: MXROF) (FSE: M1D2) ("Max" or the "Company") is pleased to report that Max will be conducting an airborne high-resolution LiDAR survey over the entire 700ha Mora mining concession KK6-08031, located within the productive Middle Cauca Gold Belt host to several world class gold deposits, 85-km south of Medellin, Colombia, which the Company has the exclusive right to purchase 100% (refer to Figures 1 and 2).

Highlights

• The LiDAR survey forms part of the initial steps to delineate high priority drill locations within the BQ, BX, NAN targets and identify new targets.
• To date, 33 artisanal underground mines are noted in historic technical reports of which Max has successfully mapped 9 inactive mines. The depth or advance of the artisanal mines varies between 5.0m and 90.5m. LiDAR can identify hidden artisanal mines/works due to tree and plant cover.
• Channel sampling artisanal underground mines is very important, it's almost like having a drillhole, identifying geological characteristics of fresh rock such as lithology, hydrothermal alterations, types of sulfides or mineralization, structures-uplifts-faults-veins and veinlets.
• LiDAR will assist in building an accurate 3D model, the key to maximizing the success of Max's planned drill program, being the first known drilling event on mining concession KK6-08031.

"The LiDAR datasets will be used to delineate drill design on the BX, BQ and NAN targets, providing unprecedented ground details to be observed for the first time," says Max Head Geologist Sergio Cocunubo.

"Sampling of artisanal mines and workings were significant steps conducted at Collective Mining's Guayabales and Continental Gold's Buritica in which we identified geological characteristics and confirmed active galleries in gold and silver production," he concluded.

Figure 1. The LiDAR survey will consist of GSD (ground sampling space) between 2 and 7 cm. Longitudinal overlap 80%, lateral overlap 75%, gimbal tilt angle — camera 90° with additional 60° photographs, flight speed of 8 m/s —maximum 10 m/s, 155.5 line-km with 45-50m line spacing covering approximately 7.16km².

Surface samples collected from San Juan and NAN by their nature are selective samples and may not be indicative of underlying mineralization.

What is LiDAR?

LiDAR is a relatively new technology whereby surface geomorphology patterns and outcrop patterns suggestive of underlying geology and structure can be identified including subtle aspects and seeing through the surface trees and plant cover that can hide surface details.

LiDAR is a modern remote sensing technique that concurrently takes high-resolution (hi-res) images and builds a detailed digital terrain model (DTM) and detailed digital surface model (DSM) utilizing an extremely sensitive and accurate digital mapping tool. Together, the DTM and Hi-Resolution images provide three-dimensional (3D) model of the terrain, where additional data (geophysics, drilling, surface sampling, etc.) can be incorporated to provide a multi-dimensional model from which multiple data sources can be interpreted accurately, all in 3D high-accuracy system with more precise, efficient, and reliable geospatial data acquisition. It delivers a turnkey solution for 3D data collection and high-accuracy post-processing. In addition, is a particularly powerful tool for drill planning as it significantly reduces the risk of interpreting data in only two dimensions.

LiDAR is the acronym for Light Detection and Ranging. It is a relatively new active remote sensing technology using a laser scanner, Global Positioning System (GPS) RTK with GNSS station, and inertial navigation. In the same way that SONAR uses sound waves and reflection to detect targets and determine distance (think of the ping heard in a submarine scene from a war movie), LiDAR uses laser pulses with their timed reflectance to determine the target distance. This process is illustrated in Figure 3.

The LiDAR survey distinguishes down to the multi-centimeter scale coupled with orthophotography remote sensing images and techniques. This combination of LiDAR and orthophoto combined relies on rigorous, high-quality data collected under strict QA/QC standards and is most useful for delineating linear features such as faults, uplifts, quartz veins or resistant rock types with hydrothermal alteration such as silicification.

Discussion of the Mora Gold-Silver Project

In August 2025, through its wholly owned subsidiary Maximum Company Colombia S.A.S., Max entered into a purchase agreement to acquire 100% of the common shares of Inversiones Villamora S.A.S., a Company in Colombia that owns 100% of mining concession number KK6-0831 ("Mora Property").

Highlights

• The undrilled Mora Property encompasses over 40 historic workings, 5 active mines, a series of exposed polymetallic structures over 2,500m by 1,000m, adjacent to Aris Mining's (NYSE: AIMN) 9.2Moz Marmato Gold Operation (P&P Reserves: 31.3Mt@3.2 g/t Au for 3.2Mozs, M&I Resources: 61.5Mt@3.0 g/t Au for 6.0Moz, Inferred Resources: 35Mt at 2.4 g/t Au for 2.8Mozs ¹).
• Aris Mining's Marmato Property abuts the 2.8 km eastern boundary, and Collective Mining's (NYSE: CNL) Guayabales Project abuts along 3.7 km north (Apollo Porphyry System), west, south, and vertical east boundaries of the Mora Property.
• Highlight, Mora Property channel sample results include (refer to Table 1)
  • 45.0 g/t gold & 7,110 g/t silver over 1.0m; 32.0 g/t gold & 53 g/t silver over 1.0m.
  • 27.0 g/t gold & 732 g/t silver over 1.0m; 8.9 g/t gold & 75 g/t silver over 1.5m.

Max advises investors that the gold mineralization at the Marmato gold deposit and the Apollo porphyry zone may not necessarily by indicative of similar mineralization at the Mora Property. Max further advises the QP has been unable to verify the information on Marmato and Guayabales and that the information is not necessarily indicative to the mineralization on the Mora Property.

In September 2025, Max reported the appointment of Mr. Sergio Cocunubo as Head Geologist, reuniting with key Technical Advisor Dr. Chris Grainger and Community Relations specialist Mr. John Henao, all key members of the Collective Mining and the Continental Gold team that developed the Buriticá Gold Deposit³ Deposit (P&P Reserves: 3.8Mozs at 6.9 g/t Au & 13Mozs at 24g/t Ag in 15.61Mt and M&I Resources: 4.4Mozs at 8.9 g/t Au & 14.6Mozs at 29 g/t in 14.02Mt plus Inferred Resources: 5.1Mozs at 8.9 g/t Au & 18Mozs at 29 g/t Ag in 16.2Mt³), sold to Zijin Mining for US $1.4 billion in 2019.

The Company's 2025 exploration program is well underway, includes collection of geological and geophysical data, channel sample all active and historical artisanal mines/workings, outcrops, airborne LiDAR, 3D geological/DTM/topographic modelling and delineation of drill targets. Exploration update is due shortly.

Under the terms of the Agreement, whereby the Company's wholly owned Colombian subsidiary, Maximum Company Colombia S.A.S. ("Maximum") has the exclusive rights to acquire 100% of Mining Concession No. KK6-08031 through the purchase of Inversiones Villamora S.A.S., to date, Max confirms option payments totaling USD $250,000.

The Company has entered into a debt settlement agreement with an arm's-length creditor to settle outstanding indebtedness totaling $60,000 (the "Debt Settlement"). Pursuant to the Debt Settlement, the Company will issue 500,000 common shares at a deemed price of $0.12 per share. The board of directors has determined that completing the Debt Settlement is in the best interests of the Company as it will preserve cash for working capital purposes and strengthen the Company's balance sheet. The Debt Settlement remains subject to TSX Venture Exchange approval. All shares issued will be subject to a hold period of four months and one day from issuance.

In addition, the Company has granted 11,500,000 Performance Share Units ("PSUs") to certain consultants of the Company pursuant to the Company's Omnibus Equity Incentive Compensation Plan (the "Omnibus Plan"). The PSUs will vest upon the consultants completing one year of service with the Company. All PSUs are subject to a hold period of four months and one day. The PSUs have been granted under and are governed by the terms of the Company's Omnibus Plan.

Quality Assurance

Max adheres to a strict QA/QC program for sample handling, sampling, sample transportation and analyses. All 21 rock samples were taken by the Max consulting geologist, labelled, placed in sealed, securitized bags and shipped to ALS Lab's sample preparation facility in Medellin, Columbia. ALS Medellin is an ISO 9001: 2008 certified facility and is independent of Max. All samples were analyzed using ALS procedure ME-ICP61, a four-acid digestion with inductively coupled plasma finished. Over-limit gold is determined by ALS procedure Au-GRA21 a 30-gram fire assay with a gravimetric finish. Over-limit silver, lead, arsenic and zinc were determined by ALS procedure OG-62, a four-acid digestion with an atomic absorption spectroscopy finish.

At this early stage of exploration, Max has relied on the QA/QC protocol's employed by ALS.

Sierra Azul Copper-Silver Project in Colombia

Max's wholly owned Sierra Azul Copper-Silver Project sits along the Colombian portion of the world's largest producing copper belt (Andean belt). Max has an Earn-In Agreement ("EIA") with Freeport-McMoRan Exploration Corporation ("Freeport"), a wholly owned affiliate of Freeport-McMoRan Inc. whereby the fully funded USD $4.8m 2025 exploration program is well underway. Updated exploration results are due shortly.

Florália Property in Brazil

The Florália Iron Property (mineral right 832.022/2018) in Brazil lies within Minas Gerais, Brazil's largest iron ore and steel producing State. The Property has established road access to rail terminal (15 km) linking to steel mills and shipping ports; roads connect to DSO buyers Vale (16 km) and ArcelorMittal (26 km) ensuring efficient logistics and market access. Max's technical team has significantly expanded the Florália Iron Geological Target from 8-12Mt at 58% Fe to 50-70Mt at 55%-61% Fe (refer Figure 4).

Max's majority owned Max Iron Brazil Ltd. has entered into a non-binding letter of intent with Bolt Metals Corp. ("Bolt") whereby Bolt may acquire an option to earn a 100% interest in the Floralia Property mineral right 832.022/2018 in Brazil (the "Property"). Under the proposed terms, Bolt will pay USD$200,000 to Jaguar Mining Inc. on behalf of Max Iron Brazil Ltda. ("Max Brazil"), keep the Property in good standing, and issue an aggregate of 26,200,000 common shares to Max Brazil and 6,094,679 common shares to Max Resource Corp. over a 30-month period. Completion of the transaction remains subject to satisfactory due diligence, definitive documentation, and applicable regulatory approvals.

Max cautions investors the potential quantity and grade of the iron ore is conceptual in nature, and further cautions there has been insufficient exploration to define a mineral resource and Max is uncertain if further exploration will result in the geological target being delineated as a mineral resource. Hematite mineralization tonnage potential estimation is based on in situ high-grade outcrops and interpreted and modelled magnetic anomalies. Density value used for the estimate is 2.8t/m³. Hematite sample grades range between 55-61% Fe. The 58 channel samples were collected for chemical analysis from in situ outcrops in previously mined slopes of industrial materials.

Aris Mining struck a deal to buy the outstanding interest in a Colombia gold development project for $80 million, setting it on a path to develop the asset and its target of producing 1 million ounces of gold a year.

The Canadian company, which already operates two underground mines in Colombia, said Thursday it has signed a binding term sheet to buy the remaining 49% interest in the Soto Norte venture from MDC Industry, known as Mubadala.

The price tag includes $60 million in cash and 1.7 million newly issued Aris shares, which will be issued at a price of $11.50 each, an almost 3% discount to the last closing price on the NYSE American exchange.

Aris said the transaction, which is expected to close early next month, includes the termination of an associated precious metals stream previously granted to Mubadala.

Aris's shares were up 3.6% in premarket trading in New York.

Chief Executive Neil Woodyer said that with 100% ownership of Soto Norte, alongside full control of the Segovia, Marmato and Toroparu operations, Aris has scaled to a point where its "buy-and-build" strategy naturally shifts to a clear focus on building.

The portfolio of projects, a strong financial position and cash flows from existing mines positions the company to expand toward becoming a 1-million-ounce-a-year producer, Woodyer said.

Aris first picked up a 20% interest in Soto Norte in April 2022 and subsequently increased its ownership to 51% through the acquisition of an additional interest in mid-2024. A pre-feasibility study has been completed on a smaller-scale development plan, and Aris said environmental studies are being finalized and are scheduled to be submitted in the first half of 2026 to initiate the licensing process.

The company has ambitions to become a leading South America-focused gold mining company. It operates the Segovia and Marmato Complex in Colombia, which together produced 210,955 ounces of gold in 2024.

VANCOUVER, BC, Nov. 20, 2025 /PRNewswire/ - Aris Mining Corporation (Aris Mining or the Company) (NYSE-A: ARMN) announces that it has entered into a binding term sheet to acquire the remaining 49% interest in the Soto Norte joint venture in Colombia from MDC Industry Holding Company LLC (Mubadala). The transaction includes the termination at closing of the associated precious metals stream previously granted to Mubadala. The total consideration is US$80 million, comprised of US$60 million in cash and 1,739,130 newly issued Aris Mining common shares, issued at a deemed price of US$11.50 per share(1) and subject to a four month plus one day hold period. The transaction is expected to close by early December 2025, subject to final documentation and customary closing conditions.

Neil Woodyer, CEO of Aris Mining, commented: "With 100% ownership of Segovia, Marmato, Toroparu, and now Soto Norte, Aris Mining has scaled to a point where our buy-and-build strategy naturally shifts to a clear focus on building. Backed by a portfolio of high-quality projects, a strong financial position, and robust operating cash flows from our existing mines, we now have a diversified, fully owned growth pipeline toward becoming a 1-million-ounce-per-year gold producer(2) . Importantly, our recent settlement agreement with the Government of Colombia underscores how collaboration is essential to advancing major projects in the country and reinforces the strong foundations for long-term success."

Strategic Rationale

• Strengthened project pipeline: With Segovia, Marmato and Toroparu advancing, full ownership of Soto Norte positions Aris Mining to become a 1,000,000-ounce-per-year gold producer2. Soto Norte is a key long-term growth asset that complements the ongoing expansions at Segovia and Marmato in Colombia and the near-term advancement of Toroparu in Guyana, which is expected to be construction-ready following completion of the PFS next year.
• Full alignment and strategic control: 100% ownership enhances Aris Mining's ability to advance Soto Norte as a core long-term growth asset.
• Highly accretive transaction on a per-share basis: The transaction structure results in a material increase in the Company's total attributable gold mineral reserves and resources on a per share basis as well as NAV accretion.

Soto Norte Overview

Aris Mining first acquired a 20% interest in Soto Norte in April 2022 and subsequently increased its ownership to 51% through the acquisition of an additional 31% interest in June 2024. Since then, the Company has advanced the project through a new smaller-scale development plan, culminating in a positive Prefeasibility Study completed in September 2025. The PFS confirms Soto Norte as a high-grade, long-life underground gold project that incorporates industry-leading environmental and social design features, including a processing plant with 20% excess capacity (750 tpd) to facilitate local, small scale miner formalization and a processing flowsheet with no cyanide or mercury use. Environmental studies are being finalized ahead of licensing submissions planned for H1 2026.

About Aris Mining

Founded in September 2022, Aris Mining was established with a vision to build a leading South America-focused gold mining company. Our strategy blends current production and cashflow generation with transformational growth driven by expansions of our operating assets, exploration, and development projects. Aris Mining intends to unlock value through scale and diversification. The Company is listed on the TSX (ARIS) and the NYSE-A (ARMN) and is led by an experienced team with a track record of value creation, operational excellence, financial discipline and good corporate governance in the gold mining industry.

Aris Mining operates two underground gold mines in Colombia: the Segovia Operations and the Marmato Complex, which together produced 210,955 ounces of gold in 2024. With expansions underway, Aris Mining is targeting an annual production rate of more than 500,000 ounces of gold, driven by the commissioning of a second mill at Segovia, completed in June and ramping up during H2 2025, and the construction of the Bulk Mining Zone at the Marmato Complex, with first gold expected in H2 2026.

In Guyana, Aris Mining owns the Toroparu gold project, where a new Preliminary Economic Assessment has been completed and a Prefeasibility Study is in progress. Following completion of the PFS, Toroparu will be positioned to advance toward construction.

Aris Mining also holds a 51% interest in the Soto Norte gold project, where a Prefeasibility Study has been completed on a smaller-scale development plan confirming Soto Norte as a high-grade, long-life project with strong economics and industry-leading environmental and social design features. Environmental studies are being finalized, which are scheduled to be submitted in the first half of 2026 to initiate the licensing process.
