Heritage Mining has mobilized its Fall Exploration Program at the Zone 3 Extension Mega-Quartz Vein System at its Drayton-Black Lake Project, following a September 11, 2025 press release. The program aims to systematically explore the newly discovered ~74m wide quartz vein system and evaluate various target areas with a focus on soil/till surveys.
Heritage Mining Mobilizes Aggressive Exploration Program at Zone 3 Extension Mega-Quartz Vein System at its Flagship Drayton-Black Lake Project ”) is pleased to announce further to the press release dated September 11, 2025, the Company has mobilized its Fall Exploration Program at Zone 3 Extension Mega-Quartz Vein System at its Flagship Drayton-Black Lake Project .
Which has confirmed broad gold zone within a newly discovered ~74m wide quartz vein system associated with a magnetic anomaly that extends for ~4km along strike length and is up to 200m in width at its flagship Drayton Black Lake Project September 9, 2025 press release.Follow-up Soil/Till Survey – success based on Orientation Survey expected Q4 2025“We grateful to our technical team to have earlier than expected availability to further explore the newly discovered Zone 3 Extension Mega-Quartz Vein Structure systematically. Our team has developed a comprehensive approach to further exploring this area as well as broader exploration programs before winter. I would like to thank the exploration team for their strong efforts.”Click Image To View Full SizeThe purpose of the soil and till program is to Rapidly evaluation the newly identified Zone 3 Extension – Mega Quartz Vein Structure 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 positions where podzolic Bf/Bh horizons preserve pathfinder chemistry. Soil/till program will be solidified following an orientation survey of key areas. The outcome of this program is to identify Pathfinders for each target defined and identify near surface mineralization footprint across target areas.The Company has received a stripping permit for the area above HML25-013 along the newly identified Zone 3 Extension – Mega Quartz Vein Structure. Stripping this area with follow on sampling and structural evaluations are planned for the Company’s 2025 Exploration program at DBL. The result of this program is to further evaluate the structural discovery at surface to better prioritize further targeting methods.Additional scout diamond drilling is planned for the 2025 exploration program at the newly identified Zone 3 Extension – Mega Quartz Vein Structure. Following the completion of Soil/Till Program and Stripping and Structural Evaluation the Company intends to commence scout drilling with additional data. The Company may initiate the scout drilling program earlier depending on additional internal evaluation.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.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.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.The ALS procedure for PhotonAssay involves lab applying preparation codes LOG-21 , CRU-31 and SPL-32a 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 and PUL-32m are then applied followed by analytical code ME-MS61 .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.The Company is a Canadian mineral exploration company advancing its two high grade gold-silver-copper projects in Northwestern Ontario.
