Multiple high-grade gold vein systems channel sampled at Drayton-Black Lake
VANCOUVER, BC, - TheNewswire - November 03, 2022 – Heritage Mining Ltd. (CSE:HML) ("Heritage" or the "Company") is pleased to report the completion of the 2022 field program at the Company’s 15,257 Ha Drayton-Black Lake Project (“DBL”). DBL is located approximately 20 km northeast of Sioux Lookout, Ontario (Fig. 1) and covers 30 km of the Central Volcanic and Southern Sedimentary domains within the Eagle-Wabigoon-Manitou (“EWM”) Greenstone Belt, which also hosts Treasury Metals Inc.’s Goliath Gold-Silver Complex immediately to the southwest. This year’s exploration program included property-wide Mag/EM airborne geophysical surveying, regional mapping, prospecting and sampling in addition to the recently completed channel sampling work.

Peter Schloo, CEO of Heritage Mining commented, “Our first pass field program at Drayton-Black Lake Project confirms the area is a highly prospective, yet significantly underexplored mineral district. Our systematic boots on the ground exploration philosophy has been highly successful, with the team discovering multiple new veins and extending known vein systems along strike. Multiple meter-scale quartz veins and quartz stockwork zones reported high grade gold assays in rock grabs from Alcona-Main (58.1 g/t Au), Alcona-New Millennium (46.5 g/t Au) and Moretti (208.0 g/t Au) project areas (see Figure 1). To optimize our drill target prioritization, we recently completed systematic channel-sampling across these high-grade structures and look forward to reporting assays when received. These initial results, along with the highly anticipated channel-sample data, will provide Heritage valuable information as we plan systematic follow up for the winter and into the 2023 exploration program."

Program Summary
The 2022 field program focused on characterizing known high-grade mineralization for the planned follow-up drill program (e.g., vein type, structural setting, alteration and mineralogical characteristics) and was successful in confirming numerous surface exposures of high-grade Au and Au-Ag mineralization throughout the property. This is the first time a systematic “belt-scale” approach has been undertaken in the Drayton-Black Lake area, building off a compilation of historic exploration program data sets, enhanced with new systematic mapping, sampling and multi-element geochemistry to develop multi-scale exploration vectors.
A recently completed channel sampling program included forty-eight individual channels) ranging from 1 to 18 m in length (average 3-5 m), see Figure 2. In total, 323 samples (279 rocks and 44 QAQC samples) were submitted for Au + multi-element analysis. Samples were delivered to the lab in Thunder Bay in three batches. Outcrops were cleaned and mapped prior to marking for channel sampling. Channels were oriented to cross veins and deformed host rock and or oriented to cut dominant or distinct vein arrays or deformation/alteration exposures. Samples were marked at 1 m intervals (from start to end) and subdivided into 0.5 m intervals where single veins or discrete mineralization was noted. Where only partial samples (within marked metreage) were collected due to cover or poor ground conditions, a percent sample was noted. Sample weights averaged 3-5 kg. Blind field duplicates (where required by our Quality Management System) were prepared by collecting an individual sample, bagging, mixing and splitting the sample to provide two equal (by weight) sub-samples for that interval.

Several significant relationships (e.g., high Ag and Te tenors) and new prospect areas were recognized and these data will be used to improve exploration vectors as the Company advances the Property. Our work has confirmed that DBL contains an extensive, shallow, high-grade Au (+Au-Ag), structurally controlled mineral system that includes many untested high-grade prospects (e.g., New Millennium) and other prospects that have only seen limited drill-testing by previous operators (e.g., Alcona-Pond and Moretti Main). Several new prospects (Au >0.1 ppm) were also identified through regional prospecting and will be added the prospect pipeline for additional follow-up work.
Based on field observations and analytical results, the Company has noted the lack of visible gold (“VG”) in many samples with grades above 20-30 g/t Au. Preliminary multi-element analysis indicates a positive relationship between Au-Ag-Te. Therefore, to better understand the character of the high-grade Au mineralization and improve exploration vectors, the Company has initiated a deportment study for Alcona, Moretti and New Millennium. Six (6) samples have been sent to Actlabs in Dryden, Ontario for complete multi-element and QEMSCAN (Quantitative Evaluation of Materials by Scanning Electron Microscopy) analysis.

ABOUT THE DRAYTON-BLACK LAKE PROJECT
The Drayton-Black Lake Project is located near the town of Sioux Lookout in Northern Ontario and comprises more than 15,000 Ha within the Eagle-Wabigoon-Manitou (“EWM”) Greenstone Belt along strike of and contiguous with Treasury Metals Inc.’s Goliath Gold-Silver Complex. There are numerous historic high-grade gold (silver, copper) prospects throughout the property within the Central Volcanic domain. All set within a broad multi-kilometer regional-scale deformation corridor with associated secondary and tertiary structural elements. Mineralization is typically shear-hosted quartz-carbonate veins with minor sulphides (1-5%). Locally, mineralized massive sulphide (Py +/- Cpy) occurrences have been documented. Some of the more sulphide rich Au + Au-Ag occurrences in the Southern Sedimentary domain have been notionally reclassified (e.g., Treasury Metal Goliath Deposit) as a hybrid or pre-orogenic atypical greenstone gold (POAGG).
Heritage employs a rigorous quality management system for field sampling and analysis. All samples and sample sites are described, photographed and geo-referenced and digitally archived at the time of sample collection. Material is securely bagged at the sample site and returned to the field office for secure storage. Sampled are delivered by Company personnel to the ALS laboratory in Thunder Bay, Ontario for prep. Samples are crushed (min. 1 kg) and pulverized (250 g; PREP-31A). Au values are determined by 50 g fire assay (Au-AA24), overlimit (Au) are treated with a gravimetric finish (Au-GRA22) and overlimit Ag are treated with acid digestion and ICP/FA finish (Ag-OG62). Multi-element analysis is provided by ICP-MS (ME-MS61). Blind duplicates, blanks and CRM (Certified Reference Materials) are inserted on a regular basis and pulps and rejects are retained for check and duplicate analysis.
