VANCOUVER, BC, October 9, 2025 – TheNewswire - Heritage Mining Ltd. (CSE: HML FRA:Y66) (“Heritage” or the “Company”) is pleased announce preliminary results from its Fall 2025 diamond drill program at Zone 3 extension, Drayton Black Lake project (“Project”). The first hole has intersected the Mega Quartz Vein Structure ~185m along strike. Two additional holes have been completed and are currently being processed, they intersected a major northeast-southwest striking linear magnetic feature that is within the granite. The first scout hole (HML25-016) intersected the Mega Quartz Vein Structure at approximately ~15m in core length (True width unknown).
2025 Fall Exploration Program - Zone 3 Extension Drill Highlights (HML25-016, Figures 1-8):
-
Drilling extended a broad zone of granite hosted quartz vein mineralization ~ 185m
-
Vein width is ~15.51m in core length (from 87.49.00m to 103.00m), true width unknown

-
Locally visible sulphides, including molybdenite and pyrite, occurring with alteration comprising silica, hematite and K-feldspar
-
15.51m of sulfide bearing quartz similar to gold mineralization intervals from HML25-013 press released September 9, 2025 and highlighted below:
-
0.98 g/t Au over 5.00m from 101.00m
-
1.11 g/t Au over 11.09m from 115.91m Including: 4g/t Au over 2m from 125m
-
-
Drill core is being logged, split and sent for assay as soon as possible
2025 Fall Exploration Plans – Zone 3 Extension:
-
Soil/Till Orientation Survey over Zone 3 Extension Area – Near Completion
-
Follow-up Soil/Till Survey – success based on Orientation Survey (Figure 1) expected Q4 2025, weather permitting
-
Outcrop/Vein stripping permit received above HML25-013 – In Progress
-
Initiate a structural Study of the Mega-Quartz Vein System
-
Diamond Drilling Q4, 2025/Q1 2026 (Figure 3) – Near Completion
“We are extremely pleased to have extended such a broad vein zone in the first scout hole at Zone 3 Extension prospect Fall 2025 exploration program. Heritage’s geologists have observed additional intense sulfide bearing quartz similar to that associated with gold mineralization from HML25-013, 185m away. This is an excellent start to Heritage’s Fall scout drill program. We also look forward to communicating additional drill results, soil orientation program and stripping results at the Zone 3 Extension Target in due course.
