HERITAGE ESTABLISHES FIRST EVER YEAR-ROUND ACCESS AND RECOMMENCES DRILLING, AT THE MELBA PROJECT

Heritage Mining Ltd. has reached a major infrastructure milestone at its Melba project and recommenced its continuing diamond drill program, located approximately 22 kilometres northeast from Kirkland Lake and 90 kilometres southeast of Timmins in Northeastern Ontario, Canada.

For the first time in the project's history, Heritage has upgraded approximately 5.5 kilometres of the former winter access trail to support year-round access for diamond drilling and exploration equipment and crews. This improvement materially enhances the company's ability to conduct systematic, multiseason exploration at Melba and to follow up on the property's encouraging historical gold results without being restricted to a short winter operating window.

With access improvements completed, diamond drilling has recommenced. Drill hole ML3800-002 has been completed, and assays are pending, while ML3800-003 is currently in progress.

Melba diamond drill program highlights:

• First-ever year-round access established, following improvements to approximately 5.5 km of the historical winter trail;
• Year-round access is expected to improve operating flexibility, reduce seasonal limitations and support more efficient follow-up drilling;
• The upgraded access provides Heritage with the ability to systematically test and expand upon historical gold-bearing structures and previously identified mineralized zones;
• ML3800-002 completed -- assays pending;
• ML3800-003 currently being drilled;
• Drilling is focused on advancing the company's understanding of the controls, continuity and potential scale of gold mineralization at the Melba project through oriented core and structural study.

The establishment of permanent access represents an important step in unlocking the Melba project's exploration potential. Historical work identified significant gold-bearing quartz-vein and structural targets; however, previous exploration was constrained by limited seasonal access. Heritage can advance the project on a year-round basis and conduct more consistent drilling, geological mapping, geophysics and follow-up exploration.

"Establishing the first ever year-round access to the Melba project is a major milestone for Heritage. Historically, exploration at Melba was limited by seasonal access despite encouraging gold results and a compelling structural setting. The upgraded access allows us to move beyond short winter campaigns and systematically test the project throughout the year. With drilling now recommenced, assays pending from ML3800-002 and ML3800-003 under way, we are well positioned to accelerate the evaluation of Melba's gold potential," commented Peter Schloo, president, chief executive officer and director of Heritage.

The Melba project is located approximately 22 kilometres northeast from Kirkland Lake and 90 km southeast of Timmins in Northeastern Ontario, Canada. The project is composed of approximately 3,886 hectares. Melba lies along the Ross fault, which is a splay off the Porcupine-Destor fault zone and is associated with development-stage and historic producing gold mines: McEwen Mine (Grey Fox mine, greater than one million ounces Au) approximately 22 km away, and the Ross mine (greater than one million ounces Au) approximately 16 km away.

Heritage Mining adheres to a strict quality assurance/quality control 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 drill hole name and identified in numerical sequence starting from beginning of the hole to the end. Wooden blocks with the corresponding downhole metreage were inserted after every drill run. Drill core boxes were transported by drilling contractors to the on-site logging facility where company personnel would take over the core handling.

Sampling, subsampling and laboratory analysis for Heritage Mining's 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 operates under a commercial contract with Heritage Mining. Drill core samples are shipped to Paragon for sample preparation at its facilities in Timmins, Ont. 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 by bar code), PREP-PKG (weigh, dry at 100 C, crush to 70 per cent passing two millimetres, riffle split approximately 500 gram into a PA jar and 250 g for pulverization to 85 per cent passing 75 micron) followed by analytical code Au-PA01, which is a non-destructive gold analysis method using high-energy X-rays with a gold detection range from 0.015 part per million to 350 ppm. After gold assays are returned, Heritage then may choose to perform multielement assays on selected samples based on the gold results first with Paragon. In these cases, an aliquot is taken from the previously prepared 250-gram split for analysis by 48MA-MS (four-acid digestion followed by multielement ICP-MS analysis for a 48-element suite).

Quality assurance/quality control

The drill program design, QA/QC and interpretation of results are performed by qualified persons employing a rigorous QA/QC program consistent with industry best practices. Standards and blanks account for a minimum of 10 per cent of the samples, in addition to the laboratories' internal quality assurance programs. Quality control data are meticulously evaluated upon receipt from the laboratories for any failures. Appropriate corrective action is taken if assay results for standards and blanks fall outside of allowed tolerances. All results disclosed by Heritage Mining have passed the company's stringent quality control protocols. The company does not recognize any factors of drilling, sampling or recovery that could materially affect the accuracy or reliability of the assay data disclosed. The assay data disclosed in this press release have been verified by the company's qualified person against the original assay certificates. Heritage Mining notes that it has not completed any economic evaluations of its Melba project, and the project does not currently have any resources or reserves.
