HERITAGE SECURED PROPERTY - WIDE MAGNETIC AND ELECTROMAGNETIC DATA, AT THE MELBA PROJECT

Heritage Mining Ltd. has secured property-wide, airborne magnetic and electromagnetic data covering its Melba project, located approximately 22 kilometres northeast from Kirkland Lake and 90 km southeast of Timmins in Northeastern Ontario, Canada.

The newly secured geophysical data sets complement the recently obtained property-wide, high-resolution lidar data and provide Heritage with an expanded technical platform for structural interpretation, geological modelling and new exploration target generation across the Melba project.

The magnetic data set includes total field magnetic information and magnetic derivative products that can assist in identifying magnetic contacts, lithological boundaries, structural breaks, intrusive bodies and areas of geological complexity. The EM data set provides an additional tool for identifying conductive responses that may be associated with sulphide mineralization, graphitic horizons, alteration zones or other conductive geological features.

When integrated with the company's high-resolution lidar data, the magnetic and EM data sets will allow Heritage's technical team to evaluate the project from both a surface structural and subsurface geophysical perspective.

The combined data sets will be used to:

• Interpret regional and property-scale structural trends;
• Identify faults, shear zones, folds and structural intersections;
• Map magnetic contacts and potential lithological boundaries;
• Evaluate conductive EM responses and their relationship to interpreted structures;
• Identify areas where magnetic, EM and lidar features coincide;
• Refine existing exploration targets; and
• Generate new priority areas for mapping, prospecting, sampling and potential drill testing.

The company considers the acquisition of the magnetic, EM and lidar data sets to be an important advancement for the Melba project. The integration of multiple independent data sets can improve target confidence by highlighting areas where structural complexity, magnetic boundaries and conductive responses overlap.

"Securing the property-wide magnetic and EM data sets represents another major step forward in our systematic evaluation of the Melba project. When combined with the high-resolution lidar data recently obtained by the company, we now have a powerful group of complementary data sets that can be used to better understand the structural and geophysical architecture of the property.

"Lidar allows us to identify subtle surface lineaments and structural patterns while the magnetic and EM data provide important information regarding subsurface geological contacts, structural breaks and conductive responses. The real value comes from integrating these data sets and identifying areas where multiple exploration indicators coincide.

"We believe this integrated approach has the potential to materially improve target generation at Melba and identify areas that may not have been recognized through historical exploration alone. Our technical team is actively reviewing the data, and we look forward to updating the market as new priority targets are developed and advanced," commented Peter Schloo, president, chief executive officer and director of Heritage Mining.

Integrated target generation

Heritage intends to integrate the magnetic, EM and lidar data sets with available geological mapping, historical exploration results and other technical information from the Melba project.

Particular emphasis will be placed on identifying:

• Conductive responses located along interpreted faults or shear zones;
• EM anomalies associated with magnetic contacts or magnetic breaks;
• Structural intersections identified from lidar and magnetic data;
• Areas of disrupted or folded magnetic stratigraphy;
• Repeating structural corridors;
• Potential extensions of historically identified mineralized trends; and
• Areas displaying multiple coincident geological and geophysical indicators.

The company's initial interpretation will be used to rank exploration areas and guide future field programs. Follow-up work may include geological mapping, prospecting, geochemical sampling, ground geophysics and drill target evaluation.

The Melba project is located approximately 22 km 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: the McEwen mine (Grey Fox mine, greater than one million ounces Au) approximately 22 kilometres away, and the Ross mine (greater than one million ounces Au) approximately 16 km away.

Technical program

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 contactors 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 the lab applying preparation codes Inv-Sam (sample logging by bar code), Prep-Pkg (weigh, dry at 100 C, crushing to 70 per cent passing two millimetres, riffle split approximately 500 grams into a PA jar and 250 grams for pulverization to 85 per cent passing 75 micrometres) 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.
