(TheNewswire)
VANCOUVER, BC, September 30,2025 – TheNewswire – Heritage MiningLtd. (CSE: HML FRA: Y66) (“Heritage” or the “Company”) is pleased to announce further to the pressrelease dated September 11, 2025, the Company has mobilized its FallExploration Program at Zone 3 Extension Mega-Quartz Vein System at itsFlagship Drayton-Black Lake Project (“DBL”). Which has confirmedbroad gold zone within a newly discovered ~74m wide quartz vein system(true width unknown) associated with a magnetic anomaly that extendsfor ~4km along strike length and is up to 200m in width (Figure 2) atits flagship Drayton Black Lake Project September 9, 2025 pressrelease.

Discussion of ExplorationProgram
Soil/Till Program
The purpose of the soil and till program is to Rapidlyevaluation the newly identified Zone 3 Extension – Mega Quartz VeinStructure as well as a broader evaluation of Alcona, Zone 10,Zone 3, and New Millennium with a terrain-aware B-horizon program.Bias sampling toward stable, well-drained eluvial–illuvial positionswhere podzolic Bf/Bh horizons preserve pathfinder chemistry. Soil/tillprogram will be solidified following an orientation survey of keyareas. The outcome of this program is to identify Pathfinders for eachtarget defined and identify near surface mineralization footprintacross target areas.
Stripping and Structural Evaluation
The Company has received a stripping permit for thearea above HML25-013 along the newly identified Zone 3 Extension –Mega Quartz Vein Structure. Stripping this area with follow onsampling and structural evaluations are planned for the Company’s2025 Exploration program at DBL. The result of this program is tofurther evaluate the structural discovery at surface to betterprioritize further targeting methods.
Scout Diamond Drilling
Additional scout diamond drilling is planned for the2025 exploration program at the newly identified Zone 3 Extension –Mega Quartz Vein Structure. Following the completion of Soil/TillProgram and Stripping and Structural Evaluation the Company intends tocommence scout drilling with additional data. The Company may initiatethe scout drilling program earlier depending on additional internalevaluation.
Conclusion
The discovery of a broad gold zone in the the newlyidentified Zone 3 Extension – Mega Quartz Vein Structure warrantsadditional systemic exploration to further develop ourdiscovery model.
Qualified Person
Stephen Hughes P. Geo, Strategic Advisor for theCompany, serves as a qualified person as defined by NationalInstrument 43-101 – Standards of Disclosure for MineralProjects and has reviewed the scientific and technical information inthis 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).

Quality Assurance/Quality Control (QA/QC)
The drill program design, QA/QC, and interpretation of
results are performed by qualified persons employing a rigorous QA/QC
program consistent with industry best practices. Standards and blanks
account for a minimum of 10% of the samples, in addition to the
laboratories’ internal quality assurance programs.
Quality Control data are meticulously evaluated upon
receipt from the laboratories for any failures. Appropriate corrective
action is taken if assay results for standards and blanks fall outside
allowed tolerances. All results disclosed by Heritage Mining have
successfully passed the Company’s stringent quality control
protocols.
The Company does not recognize any factors of drilling,
sampling, or recovery that could materially affect the accuracy or
reliability of the assay data disclosed. The assay data disclosed in
this press release have been verified by the Company’s Qualified
Person against the original assay certificates.
Heritage Mining notes that it has not completed any
economic evaluations of its Drayton-Black Lake Project, and the
project does not currently have any resources or reserves.
