Heritage Mining Acquires Property-Wide Geophysical Data for Melba Project
TORONTO, ON — August 4, 2026 — Leads & Copy — Heritage Mining Ltd. has acquired property-wide airborne magnetic and electromagnetic data for its Melba Project, located in Northeastern Ontario, Canada. The project is situated approximately 22 kilometers northeast of Kirkland Lake and 90 kilometers southeast of Timmins.
This new geophysical data complements recently obtained high-resolution LiDAR data, enhancing the company’s technical capabilities for structural interpretation, geological modeling, and the identification of new exploration targets at the Melba Project.
The magnetic dataset provides information on total-field magnetism and derivative products, which are useful for delineating magnetic contacts, lithological boundaries, structural breaks, intrusive bodies, and areas of geological complexity. The electromagnetic dataset serves as an additional tool for detecting conductive responses that may indicate sulphide mineralization, graphitic horizons, alteration zones, or other conductive geological features.
When integrated with the existing LiDAR data, the magnetic and electromagnetic datasets will enable Heritage’s technical team to analyze the Melba Project from both a surface-structural and subsurface geophysical perspective. The combined datasets will be utilized 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 in relation to interpreted structures, and identify areas where magnetic, EM, and LiDAR features coincide.
Furthermore, the integrated data will refine existing exploration targets and generate new priority areas for mapping, prospecting, sampling, and potential drill testing. Heritage Mining considers the acquisition of this comprehensive geophysical data a significant advancement for the Melba Project, believing that the integration of multiple independent datasets can increase target confidence by highlighting areas with overlapping structural complexity, magnetic boundaries, and conductive responses.
“Securing the property-wide magnetic and EM datasets represents another major step forward in our systematic evaluation of the Melba Project,” said Peter Schloo, President, Chief Executive Officer and Director of Heritage Mining Ltd. “When combined with the high-resolution LiDAR data recently obtained by the Company, we now have a powerful group of complementary datasets that can be used to better understand the structural and geophysical architecture of the property.”
Schloo elaborated that LiDAR helps identify subtle surface lineaments and structural patterns, while magnetic and EM data provide crucial subsurface geological contact, structural break, and conductive response information. He emphasized that the integration of these datasets to identify areas where multiple exploration indicators converge holds significant potential to materially improve target generation at Melba, potentially uncovering areas missed by historical exploration.
Heritage Mining plans to integrate the magnetic, EM, and LiDAR datasets with available geological mapping, historical exploration results, and other technical information pertaining to the Melba Project. The focus will be on identifying conductive responses along interpreted faults or shear zones, EM anomalies associated with magnetic contacts or 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 guide the ranking of exploration areas and inform future field programs, which may include geological mapping, prospecting, geochemical sampling, ground geophysics, and drill-target evaluation. The Melba project, comprising approximately 3,886 hectares, is situated along the Ross Fault, a splay off the Porcupine-Destor Fault Zone, which is associated with significant gold mines such as the McEwen Mine and the Ross Mine.
Heritage Mining follows a strict Quality Assurance/Quality Control (QA/QC) protocol for sample handling, transportation, and analysis, ensuring the security of samples until they reach the laboratory. All drilling at the Melba project recovers NQ core, which is systematically cut, sampled, and submitted for analysis to Paragon Geochemical in Timmins, Ontario. Paragon is an ISO/IEC 17025:2017 accredited laboratory offering methods such as PhotonAssay for gold determination and 48-element ICP-MS analysis.
The drill program design, QA/QC, and interpretation of results are managed by qualified persons adhering to industry best practices. Standards and blanks comprise at least 10% of the samples, in addition to the laboratory’s internal QA programs. All disclosed results have passed the company’s stringent quality control protocols.
Stephen Hughes, P. Geo, Strategic Advisor for Heritage Mining Ltd., serves as the qualified person for the company and has reviewed and approved the scientific and technical information presented in this news release.
Heritage Mining Ltd. is a Canadian mineral exploration company advancing its Ontario Project Portfolio in Northwestern and Northeastern Ontario. The company’s projects include Drayton-Black Lake, Contact Bay, and Scattergood, located near Sioux Lookout, and the Melba Property near Ramore, Ontario. All projects benefit from extensive historic data, accessible sites, and strong local community support.
