Heritage Mining Ltd. announced the field program results for its Contact Bay property (Contact Bay) as of October 24, 2023, a wholly owned exploration project located 12 kilometers south-southwest of the town of Dryden in Ontario. The Company has also entered into an asset purchase agreement dated September 19, 2023 to acquire two unpatented mining claims in Ontario (the Mining Claims) within the Contact Bay Project (Anderson Area) in exchange for the issuance of 100,000 common shares in the capital of the Company (the "Transaction"). Highlights: Nabish Lake Area - Confirmed economic Cu and Ni mineralization up to 1.9% Cu and 0.4% Ni across several kilometers of the Nabish Lake mafic-ultramafic intrusion; New Cu mineralization area discovered; Rognon Mine Area - Confirmed high grade gold mineralization across 2km potential shear zone; Package expansion (Anderson Claims); All areas easily accessible with year-round access.

Nabish Lake Area (Cu-Ni-PGE Target Area): Field observations and historical results indicate potential for Cu-Ni-PGE type mineralization over several kilometers of Nabish Lake mafic -ultramafic intrusion. Significant chalcopyrite, pyrrhotite, magnetite and pyrite mineralization are associated with an ultramafic mafic-ultramAFic intrusion. Out of 25 samples taken, 7 return anomalous to economic grade Cu mineralization and 5 samples returned anomalous to economic grade Ni mineralization.

New Mineralization Area grabs returning up to 0.20% copper will be an area of interest in future programs. Rognon Mine Area (Au Target Area): Shear zone/quartz vein hosted lode gold type mineralization targeted by historic workings over an approximately 2 kilometer strike length. Three historic mine shafts, numerous pits and trenches and tailings were located by the field team (Contact Bay Mine, Rognon Mine and Wachman Mine). A total of 12 grab samples were collected from this area, and 10 out of 12 samples hosted anomalous gold up to 3.86g/t Au.

Anderson Area: Exploration at this site has previously located multiple historic workings of over 350 meters of exposed shear zone hosted quartz veining. Shearing is associated with the geological contact between mafic volcanic and ultramafic rock. Significant sulfide mineralization (pyrite, chalcopyrite, Pyrrhotite) and hydrothermal alteration minerals have been identified at both locations.
