Heritage Mining Ltd. Provides Field Program Update

Program Highlights (Area/Target/Prospect)

The Company has received the final analytical results from the summer prospecting and check sampling* program at DBL. Samples were received from the Drayton, Moretti and Split Lake Areas (Fig. 1).

• At the W-H Target (Drayton Area, Fig 2), results from six samples returned values from below detection to 2.28 g/t Au, with four of the six samples grading over 1.0 g/t Au.

• At the K171 Target (Drayton Area), results from six samples returned values from below detection to 0.50 g/t Au and one sample (quartz-carbonate vein with pyrite) returned a value of 25.0 g/t Au.

• Six samples from regional prospecting (Split Lake Area) returned low Au values ranging from 0.009 to 0.022 g/t Au).

• Fifteen samples from regional prospecting at the Botsford Lake Target (Moretti Area) returned values ranging from below detection (n=11) to 0.71 g/t Au.

• Six samples from regional prospecting (Moretti Area) near the Bellekeno and Clamshell Lake Targets returned Au grades ranging from below detection (n=1) to 2.01 g/t Au, in a sulphide-rich mafic metavolcanic unit.

The summer 2022 sampling program has identified both high-grade, vein-hosted Au mineralization and moderate to low-grade volcanic-hosted Au mineralization; the latter in deformed and altered sulphide-bearing mafic rocks. Both styles of mineralization were found across a broad footprint through the DBL property.

*Grab (chip) sampling is a selective sampling method and the reader is cautioned that these samples may not represent the actual tenor of mineralization at a larger scale. Therefore, the Company has initiated a systematic channel sampling program on select prospects within the priority Targets.

The Company's systematic channel sampling program began in early October and is scheduled to be completed by the end of the month.

Peter Schloo, CEO of Heritage Mining commented, "We are pleased to report the additional assay results from our ongoing field program. A very impressive start. Systematic channel sampling on priority areas is currently well underway and anticipated to be completed by the end of the month. We look forward to communicating additional findings and drill targets to the market in timely manner, and we remain very excited about this project."

ABOUT THE DRAYTON-BLACK LAKE PROJECT

The Drayton-Black Lake flagship project is located near the town of Sioux Lookout in Northern Ontario and comprises more than 15,000 Ha within the Abrams?Minnitaki Lake 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) occurrences (incl. past mining operations) and showings throughout the property. All set within a broad multi-kilometer regional-scale shear zone and related secondary and tertiary structural elements. Mineralization is typically shear-hosted quartz- carbonate veins with minor sulphides. Data from historic reports indicate a high silver content (2:1 up to 10:1 Ag:Au) with a galena (+/- Py, Po, Cpy, Sphal) association. Locally, mineralized massive sulphide (Py +/- Cpy) occurrences have been documented. In the AML greenstone belt, some of these sulfide rich occurrences have been reclassified as a hybrid or pre-orogenic atypical greenstone gold (POAGG) by some authors (e.g., Treasury Metal Goliath Deposit).

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 to ALS laboratory in Thunder Bay, Ontario for prep and analysis. Samples are crushed (1 kg) and pulverized (250 g; PREP-31A). Au values are determined by fire assay (Au-AA23), overlimit (Au) are treated with a gravimetric finish (Au-GRA21). Multi-element analysis provided by ICP-MS (ME-MS-61). Pulps and rejects are retained for check and duplicate analysis.
