Heritage Confirms Multiple High-Grade Gold Intercepts and New Gold Zones up to 42g/t Au at Melba (TheNewswire) VANCOUVER, BC – TheNewswire - February 9, 2026 – Heritage Mining Ltd. (CSE: HML FRA: Y66) (“Heritage” or the “Company”) is pleased to announce confirmation of High-Grade Gold intercepts at the Melba Mine Project (“Melba”) with its ongoing diamond drill program. Additionally, the Company is pleased to announce the confirmation of New Gold Zones at Melba (Figure 1,2). Melba, located ~22km northeast from Kirkland Lake and 90km southeast of Timmins in Northeastern Ontario, Canada. The project is comprised of ~3,886Ha. Melba lies along the Ross Fault, which is a splay off of the Porcupine-Destor Fault Zone and is associated with development stage and historic producing gold mines: McEwen Mine (Grey Fox Mine, +1Moz Au) ~22km away, and the Ross Mine (+1Moz Au) ~16km away (Figure 3). Melba Project - Diamond Drill Program (Partial) Highlights: New Gold Zones (Figure 1,2) 2025/26 Diamond Drill Program: ML3900-002: 42.57g/t Au over 1m from 72m, finished in gold mineralization. Aligned with historical results: UG-Q-60: 34.29 g/t Au 1.4m, UG-T-60: 14.58 g/t Au 1.98m ML3850-003: 9g/t Au over 1m from 52m. hole terminated, intersected underground workings. Underground workings in area of ML3850-003:204 E Zone: 13.31g/t Au over 0.91m for 8.54m Significant Exploration Upside (Figure 1,2): Multiple Assays Pending: ML3900-003, 004, 005 Ongoing Diamond Drilling Multiple new and existing gold zones near surface Gold grades increasing at depth (Historical DDH: 37-18: 14.24g/t Au over 4.11m from 123.9m, Figure 2) “The identification of multiple new gold zones at Melba this early in the program supports significant exploration potential. Furthermore, it confirms our initial interests, underground results have not been properly evaluated. We are very excited to further understand Melba and look forward to additional results in short order.” Commented Peter Schloo, President, CEO and Director of Heritage.

The Melba Mine is located on the northeastern part of Ontario close to Ontario/ Quebec border. The claim package includes single cell mining claims spanning ~3,886 hectares and one mining lease. Technical Program Heritage Mining adheres to a strict QA/QC protocol for handling, sampling, sample transportation and analyses. Chain-of-custody protocols are designed to ensure security of samples until their delivery at the laboratory. Drill core was boxed, covered and sealed at the drill rig site. Core boxes were labelled with the official drillhole name and identified in numerical sequence starting from beginning of the hole to the end. Wooden blocks with the corresponding down hole meterage were inserted after every drill run. Drill core boxes were transported by drilling contactors to the onsite logging facility where Company personnel would take over the core handling. Sampling, Sub-sampling, and Laboratory Analysis for Heritage Mining Melba Project. All drilling at the Melba project recovers NQ core. Drill core is systematically cut in half using a diamond saw. A qualified geologist examines the drill core, marking intervals for sampling and indicating the cutting line. Sample lengths are typically 1.0 metre, adjusted to a minimum length of 0.5 metre as necessary to respect lithological and/or mineralogical contacts and to isolate narrow veins or structures that may contain higher-grade mineralization. Technicians saw the core along the cutting lines determined by the geologist. One half of the core is retained as a witness sample, while the other half is submitted for analysis. Individual sample bags are securely sealed and placed into sealed rice bags, which are then clearly marked with their contents. Heritage Mining submits samples for gold determination by PhotonAssay to Paragon Geochemical - Timmins. (“Paragon”). Paragon operates under a commercial contract with Heritage Mining. Drill core samples are shipped to Paragon for sample preparation at their facilities in Timmins, Ontario. Paragon is an ISO/IEC 17025:2017 accredited laboratory for the PhotonAssay method in addition to a variety of diverse metal determination methods. Analytical Procedures The Paragon procedure for PhotonAssay involves lab applying preparation codes INV-SAM (sample logging via barcode), PREP-PKG (weigh, dry at 100C, crushing to 70% passing 2mm, riffle split ~500g
