VANCOUVER, BC TheNewswire - May 15, 2025 Heritage Mining Ltd. (CSE: HML FRA:Y66) (" Heritage " or the " Company ") is pleased to announce preliminary results from its 2025 diamond drill program at Zone 3 extension, Drayton Black Lake project (" Project "). Two scout holes have been completed, and a third hole is in progress, testing a major northeast-southwest striking linear magnetic feature that is granite-hosted. The second scout hole (HML25-011) intersected the widest quartz vein ever drilled within the Project area to date, approximately 46m wide (true width ~32m, assuming the vein is near vertical). The Company has therefore modified the current drill program to further test this quartz-rich structure at deeper and shallower levels, as well as along strike.
Zone 3 Extension Drill Highlights:
Drilling discovered a broad zone of granite-hosted quartz vein mineralization
Widest quartz vein ever intersected at the Project
Vein width is ~46 metres (from 209.40m to 255.55m)
Locally visible sulphides include chalcopyrite, galena, pyrite and hematite staining
Drill core is being logged, split and sent for assay as soon as possible
" We are extremely pleased to have intersected such a broad vein zone in only the second scout hole at Zone 3 Extension prospect. Our geologists have observed locally significant sulphides in the quartz (galena, molybdenite, pyrite), indicating this structure acted as an important conduit for mineralized fluids. Tapping into such a broad quartz structure this early into the program underscores the significant opportunity at the Drayton-Black Lake Project for further discoveries within this established gold-rich camp. This is an excellent start to Heritage's scout drill program, and we are now redesigning the drill program to ensure this mega-structure is pierced further along strike and at a range of depths. We look forward to reporting more results from the scout program in due course." Commented Peter Schloo, President, CEO and Director of Heritage Mining.

Figure 1: HML25-011 Box 5 8 (top) to 69 (bottom), ~209.40m to ~255.55m (~46m); shows the thickest quartz sulfide vein ever intersected at Drayton-Black Lake.
Discussion of Results
The 2025 drill program at Zone 3 Extension is targeting granite-hosted mineralized quartz-vein structures that were first observed in the HML Zone 3 drilling program of August 2024. T wo scout holes (HML25-010 and -011) totalling 592m have been completed by the Company. Both drill holes tested a northeast trending linear magnetic feature that is ~2km long and up to ~200m wide hosted by the Lake of the Bays Batholith. These scout holes were drilled approximately ~1km from the nearest drill site at Zone 3 2024 drilling targets.
The first scout hole (HML25-010) intersected multiple zones of granite cut by broadly spaced, cm-scale quartz – pyrite – chalcopyrite veins. The second scout drill hole HML25-011 intersected much wider structural zones, including a massive quartz vein from 209.4m to 255.5m depth (true width ~32m), the widest quartz-vein structure ever intersected on the Project. This "Mega" quartz structure is characterized by "dirty" quartz with moderate hematite staining and locally contains disseminated and vein-hosted pyrite, chalcopyrite, sphalerite, galena and molybdenite mineralization (Figure 4). This maiden discovery of a "mega" quartz structure is highly encouraging and warrants further exploration.
