ONE STEP CLOSER TO CASH FLOW: AVERAGE GRADES OF 3.72G/T AU AND 0.96G/T AU FROM 1930S ROCKPILES AT DRAYTON - BLACK LAKE

Heritage Mining Ltd. has provided an exploration update. Further to its press release dated Oct. 23, 2025, the company is one step closer to near-term cash flow from historical tailings/rockpiles in the immediate vicinity of historical mine shafts at the Alcona mine and Split Lake mine at the Drayton/Black Lake project (DBL), located in Northwestern Ontario, Canada. The company is also pleased to announce the fully permitted mill is willing to accept rock piles given initial grade estimates and requires additional testing for processing, which has commenced at the time of this press release.

1930s rock pile sampling program highlights:

1. Split Lake mine historical rock pile exploration highlights:
   • Average grade of approximately 3.72 grams per tonne gold on approximately 5,500 tonnes from rock pile;
   • All 26 samples registered gold values from 0.009 g/t Au up to approximately 27 g/t Au;
2. Alcona mine historical rock pile exploration highlights:
   • Of the 30 samples taken, 20 samples registered gold values from 0.006 g/t Au up to 4.1 g/t Au, average grade approximately 0.53 g/t Au on approximately 40,000 tonnes of mining waste pile;
   • Approximately half of the pile returned higher-than-average gold values, supporting additional systematic sampling in this area;
   • Approximately 20,000 tonnes of mining waste pile returned an average grade of approximately 0.96 g/t Au; 12 samples all registered gold values from 0.013 g/t up to 4.1 g/t Au.

"The price of precious metals are holding strong at their current values with macro indications of continued upward movement. This scenario enables our company to consider alternative and less dilutive sources of capital. Initial grade estimates from waste piles are encouraging and supported additional testing with guidance of our board, management and strategic advisers holding a wealth of experience in this sector. We look forward further updates in short order," commented Peter Schloo, president, chief executive officer and a director of Heritage Mining.

Note: All ore/rock pile sampling has been submitted for additional acid-based accounting and multielement testing/assays. All volume calculations are approximate in nature; calculations and areas are driven by historical reports and field verification. Field verification techniques include GPS (Global Positioning System) co-ordinates and field measurements.
