Max Resource Confirms Continuation of Mineralization from Underground Channel Sampling Program on the Mora Gold Silver Property in Colombia

Vancouver, February 26, 2026 - Max Resource Corp. (TSXV: MAX) (OTC Pink: MXROF) (FSE: M1D2) ("Max" or the "Company") is pleased to announce the Company's in-country team has successfully completed systematic metre-by-metre rock chip channel sampling ("Channels") of the mineralized vein structures and from the hangingwall of the vein along the entire 47.5m of tunnels in the El Oso underground ("U/G") mine within the NAN target; one of 19 past and 5 active mines identified on the Mora Gold Silver Property ("Mora" or the "Property") situated in the Marmato gold district, 70 km south of Medellin, Colombia (refer to Figures 1 to 6 and Table 2).

The programs form part of the Mining Technical Work Plan ("PTO") to permit drilling and small-scale production. In total, 87 rock samples were collected (83 original and 4 duplicates); 46 from mineralized veins and 41 from host rock and the hangingwall; for total of 42 channels perpendicular to the mineralized veins. Mapping and channel sampling was conducted along the entirety of both levels: the 37.5m Main Level and the 10.0m Upper Level.

The El Oso U/G (active 2012 - 2015) driven at azimuth of 295°, is located at the lower most southern portion of a 5,000m long NW striking mineralized corridor which extends towards the Mora Property's BQ and BX targets, approximately 700m higher in elevation. The gently sloping tunnels have an average height of 2.0m, width of 1.6m, horizontal depth of 37.0m.

Exploration activities to date: Over the last 3 months, Max's team conducted topographic and geological mapping of historic mines/adits and outcrops, with the initial objective of outlining the continuity and widths of the 5,000m Marmato-type mineralized corridor from NAN to the BQ/BX targets to the northwest. The NAN target lies at the same elevation to the neighbouring Marmato Deeps deposit (refer to Figures 1 and 2).

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

Mining Technical Work Plan ("PTO"): Is underway over the NAN target area, including components for a mine exploitation plan and baseline environmental survey, which permits drilling and small-scale production. The Company recently completed an airborne LiDAR survey to obtain a high-resolution topographic base to produce orthophotos to assist in identifying structures, folds, faults/fractures and adits to unlock the full potential of the Mora mineralized corridor.

El Oso U/G channels: The objective of the channel sampling program is to gain an understanding of the mineralization and structure of the El Oso vein system and the greater 5,000m mineralization corridor through sampling along strike on two levels. The channel sampling should demonstrate continuity of mineralization and grade within one of the key structures within the highly prospective vein system. We look forward to receiving the assay results of this initial underground channel sampling campaign in short order.

El Cielo U/G mine: Channel sampling at the El Cielo UG is underway, also active 2012 - 2015 and located along trend 100m NW of El Oso. The 60.3m long El Cielo tunnel, 2m by 1.3m, depth of 37.0m was driven at azimuth 319°, sub-parallel to El Oso. A series of exposed polymetallic structures 2,500m by 1,000m, 19 past and 5 active mines/adits along the 5,000m mineralized corridor appears to demonstrate the Marmato deposit is part of a prolific mineralized system, the mines/adits and elevations are providing a view of the mineralized system in three dimensions.

"We are extremely pleased with the El Oso channel sampling as it demonstrates the continuity of the mineralization and structure which appears to trend onward to the El Cielo mine, suggesting the Mora mineralized corridor has potential bulk-size targets. The underground channel sampling campaign also derisks drilling targets," commented Max CEO, Brett Matich.

"We continue the Mora campaign, as Collective Mining continues to advance their Guayabales project drilling on trend to the Mora northern boundary and the NW end of the 5,000m Mora mineralized corridor and Aris Mining recently reported on increasing the Marmato annual gold production to 200,000ozs by 2026YE. Concurrently, we continue to work toward filing the PTO (Mining Technical Work Plan) which permits small-scale production and drilling," he concluded.

Max advises investors that the gold mineralization at Marmato or Guayabales may not necessarily by indicative of similar mineralization at the Mora.

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 relied on the QA/QC protocols employed by ALS.

Qualified Person

The Company's disclosure of a technical or scientific nature in this news release was reviewed and approved by Tim Henneberry, P.Geo (British Columbia), a member of the Max Resource advisory board, who serves as a qualified person under the definition of National Instrument 43-101.

Florália High Purity Iron Project in Brazil

Florália lies adjacent to the largest iron ore mines in Minas Gerais, Brazil's largest iron ore and steel producing State. Exploration Target of 50-70Mt at 55%-61% Fe. Fully funded through an option to purchase by Bolt Metals Corp. (CSE: BOLT) issuing an aggregate of 32.3m shares. The transaction is subject to satisfactory applicable regulatory approvals.

On February 23, 2026, Bolt Metals Corp. announced the closing of a Private Placement offering aggregate gross proceeds of $6,000,000.

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.
