July 2025 Exploration Update Highlights

Drilling at Drayton-Black Lake (‘ DBL ‘) – Zone 3 Extension confirms gold mineralization in a broad quartz vein structure as initially reported in Heritage’s press release dated May 15, 2025.
- DBL – Zone 3 Extension drilling intersected multiple zones of locally anomalous gold mineralization in drill hole HML25-011 associated with a 46m wide quartz zone, including 0.95 g/t Au over 1m from 237.00m; and
- Zone 3 Extension drill hole HML25-012 tested a different magnetic lineament at the periphery at the Lake of the Bays Batholith and the contact zone of this batholithic body. Two n arrow zones of up to 0.43 g/t Au over 1m were intersected.

Drilling at Contact Bay is completed. A total of 10 holes for 2,726m were drilled with assays pending.
- Drill holes locally intersected narrow quartz sulfide veins and visible gold was observed on one drill hole RGN25-004 (Figure 4).

‘We are pleased to welcome a new strategic shareholder, who aligns with Heritage’s view that systematic active exploration across all properties is the key driver. We look forward to generating value to all stakeholders.

The proposed Melba Mine acquisition (pending due diligence) offers the Company exposure to the well-known mining camp (Kirkland Lake and Timmins). We look forward to applying our active systemic exploration approach to this area in short order post-acquisition.

Although assays remain pending from Zone 3 Extension at DBL and Contact Bay we appreciate the technical success and confirmation of anomalous gold in a new area never before prospected in the Sioux Lookout Area. This is the broadest quartz vein ever intersected within the Sioux Lookout District and warrants further drilling and evaluation along strike.’ Commented Peter Schloo, President CEO, and Director of Heritage

Melba Mine Property Description

The Melba Mine is located in Northwestern, Ontario, Canada Southwest of Matheson Ontario (Figure One) approximately seven kilometres west off the King’s Highway 11, on the section of highway travelling from Kirkland Lake to Cochrane. The Melba Mine is located on the west central part of Ontario close to the Ontario and Quebec border. It’s fortunate the location of the Melba Property lies within the central hub of over 100 years of mining activities, including active mining operations within the Abitibi Greenstone Belt.

The claim package includes single cell mining claims spanning 1,522.70 hectares and one mining lease.

Property Geology

The governing element of structure appears to be a contact between dioritic greenstone to the south and argillaceous greywacke to the north. The contact trends north 50-60 degrees west and dips northward. Whether the greywacke is part of a synclinal trough of sediments that are younger than the greenstone or whether it is part of a sedimentary band belonging to the greenstone series is an unknown factor at present. The greywacke is cut by dikes of porphyry that run parallel to the contact. The main gold bearing vein, usually described as the ‘Blue Vein’, also runs parallel to the contact but lies within the sediments. It strikes north 55 degrees west and dips northward 55 degrees. It is accompanied by shearing and alteration, also by a pattern of cross fracturing that has produced faulting in the main vein and has led to the development of irregular veins in the adjacent rocks. The main vein is displaced 60 feet (18.2 metres) northward near the shaft and other displacements have been found underground. The picture resembles that of the sedimentary belt in the Beatty-Munro area. Numerous feldspar porphyry, diorite and basic syenite dikes were intersected by the drilling. Overall, a significant amount of the drill core showed alteration, some highly, while carbonate stringers were numerous and visible gold was noted in drill core.

2025 Exploration Update

Assays were delayed due to operational issues at the lab and core shack facilities; corrective measures have been implemented, and normal operations are expected to resume shortly.

Discussion of Results

DBL – Zone 3 Extension

The 2025 drill program at Zone 3 Extension targeted granite-hosted mineralised quartz-vein structures that were first observed in the HML Zone 3 drilling program of August 2024 (Figure 3). The recently completed program comprised 4 holes for a total 1105.5m targeting a northeast-southwest trending magnetic lineament. Drilling is considered a technical success with two ( HML25-011 and 013 ) of the four holes intersecting a well-developed quartz vein structure, including drill hole HML25-013 that intersected a 74m wide vein structure (true width unknown). Assays received for HML25-010, 011 and 012, with assays pending for HML25-013 & 014.

Assays for HML25-010 & 011 confirm locally elevated gold values in the vein structure, with the best intersection of 0.95g/t gold over 1 meter in drill hole HML25-011 (Figure 2). Although gold mineralization is low grade, significant exploration potential remains along strike of this well-defined linear mag feature, and further drilling is proposed to test this ‘mega-quartz vein structure’.

HML25-011 Highlights:

0.07 g/t Au over 5.5m from 212.50m to 217.00m
- Including 0.27g/t Au from 213.47m

0.95 g/t Au over 1m from 237.00m (within Quartz Vein Zone)

Contact Bay Rognon Mine Area

The 2025 drill program at Contact Bay is completed, targeting a mineralised quartz-vein structure that was historically mined in the early 1900’s. The recently completed program comprised 10 holes for a total 2726.0m. The geology comprises metavolcanic rocks cut by granitoid batholiths and gabbroic sills and stocks. The metavolcanic rocks are locally cut by cm-scale quartz-sulphide veins and drill hole RGN25-004 intersected visible gold in a quartz-pyrite vein (Figure 4). Assays are pending for all holes.

Conclusion

Although some assays remain pending, the Company believes additional drilling is warranted to test along this major quartz vein structure along strike. The Company has proposed an additional 10 holes to test along a 2km strike length of the magnetic lineament (Figure 3).

Qualified Person

Stephen Hughes P. Geo, Strategic Advisor for the Company, serves as a qualified person as defined by National Instrument 43-101 – Standards of Disclosure for Mineral Projects and has reviewed the scientific and technical information in this news release, approving the disclosure herein.

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.

Sampling, Sub-sampling, and Laboratory Analysis for Heritage Mining Drayton Black Lake Project All drilling at the Drayton Black Lake project recovers NQ core. Drill core is systematically split 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 bags, which are then clearly marked with their contents.

Heritage Mining submits samples for gold determination by PhotonAssay to ALS Canada Ltd. (‘ ALS ‘). ALS operates under a commercial contract with Heritage Mining.

Drill core samples are shipped to ALS for sample preparation at their facilities in Thunderbay Ontario. ALS 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 ALS procedure for PhotonAssay involves lab applying preparation codes LOG-21 (sample logging via barcode), CRU-31 (fine crushing so that 70% passes through a 2mm screen) and SPL-32a (rotary splitting of a representative ~500g subsample) 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 0.03 ppm to 350ppm.

After gold assays are returned, Heritage then may choose to perform multi-element assays on selected samples based on the gold results. In these cases, sample preparation codes FND-05 (locate and use remaining crushed material from Au-PA01) and PUL-32m (pulverization so that >85% passes 75 µm screen) are then applied followed by analytical code ME-MS61 (multi-element ICP-MS analysis for base metals, pathfinder elements, lithophile elements and rare earth elements).
