(CSE: HML FRA: Y66) (“Heritage” or the “Company”) is pleased to announce confirmation of more Visible Gold in Core in sampled Diamond Drill hole ML3840-003 from 72.40m within an approximate ~8m shear zone at the Melba Mine Project (“Melba”) with its ongoing diamond drill program (Figure 1,2). Melba Project – Visible Gold:  Figure 1: ML3840-003 at 72.40m, visible gold at millimeter scale “The identification of the third instance of visible gold within an ~8m shear zone at ~72m depth is very encouraging. We have also extended the planned depth of ML3840-003 to ~150m due to favourable mineralization, assays pending. We look forward to updating our stakeholders on additional exploration results in short order.” Commented Peter Schloo, President, CEO and Director of Heritage.

The target zone is a sheared felsic volcaniclastic and conglomerate contact. 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. []() 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 7
