NOT INTENDED FOR DISTRIBUTION TO UNITED STATES NEWS WIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES

VANCOUVER, BC – TheNewswire – SeptemberAugust 53, 2023 – Heritage Mining Ltd. (CSE:HML) (FRA:Y66) (“Heritage” or the “Company”) is pleased to announce AZI Drilling has completed its drill program at the Alcona Target Area and is now mobilizing to the never drilled, New Millennium Target Area onsite at its flagship Drayton-Black Lake Project and preparing to commence Heritages’s phase 1 drill program (the “Phase 1 Drill Program”) as early as Friday, August 4, 2023. The Company is also pleased to provide a program update inclusive of grab samples which returned grades up to 12.4 g/t Au and 46.7 g/t Ag and channels which returned grades up to 26.20 g/t Au and 2.18 g/t Ag pertaining to surface sampling across the priority target araeas At its flagship Drayton-Black Lake Project.

Drilling Mobilization

The Company has mobilized its diamond drill program to New Millennium from Alcona Area at its flagship Drayton- 0Black Lake Project site located in northwestern Ontario approximately 25km East of the town of Sioux Lookout, Ontario by paved highway. AZI Drilling will begin drilling in the Alcona Area, New Millennium and proceed to the Moretti Area, respectively. The Phase 1 Drill Program previously released on August 3, 3023 which consists of a 3,600m diamond drill program over the three priority target areas. commencing as early as Friday August 4th, 2023.

Further to the Company’s partnership with Mira Geoscience announced on July 20, 2023, Mira Geoscience has produced a geology model for the Alcona and New Millennium targets ahead of schedule giving the CompanyHeritage’s exploration team a focused geophysical and structural understanding as planned to test numerous targets within the Phase 1 Drill Program at New Millennium, additional targets have been provided and have been incorporated into the program. The Company will use geoscience best practices including drilling orientated core in order to capture vital structural data that will aid in the refinement of the geologic model. Oriented core is used to assess structural geology that controls mineralization.

“We are excited to have AZI Drilling moving to New Millennium, a never drilled area with the highest grab sample property wide grading 2330 g/t Au in last year’s program. We appreciated everyone’s hard work to date and I look forward to coming back to site in the near futureon site to commence our Phase 1 drill program. The exploration team has done a fantastic job setting up for the drill program ahead of schedule and under budget. They have been invaluable in the process, we appreciate their hard work, dedication, and preparedness. I have been onsite and will remain through the transition, making myself available to our teams as we progress to drilling, this is a material event for the Company, we are all hands on deck.” Commented Peter Schloo, President, CEO and Director of Heritage.

Summary of Sampling Results

The results of the surface sampling have be encouraging supporting consistent high-grade gold and gold-silver mineralization at surface across our target areas.

“The 2023 exploration team has progressed the priority targets with a razor-sharp focus. It has been an absolute pleasure working with each of our exploration team members and we look forward to developing additional targets, communicating our progress to stakeholders in the near future. I have frequented the site in recent months to provide onsite support wherever needed, we are boots on the ground, top to bottom, at Heritage and look forward to building current and new relationships in the community as we progress our projects respectfully and systematically.

We have confirmed, extended and expanded our understanding of our three priority target areas from a historical perspective.

Overall, it is a rarity in my opinion to have a high-grade, at surface, gold and gold-sliver mineralized occurrences over kilometers of strike length with two priority targets confirmed at depth from historic drilling and with such closed proximity to existing infrastructure. We look forward to advancing the project in a systemic manner by testing our models.

We look forward to updating everyone on our progress of the phase 1 drill program and are very thankful for the support to date.” Commented Peter Schloo, President, CEO and Director of Heritage.

Highlights summarized below for target areas:

Alcona Area: Broad (>200m) composite mineralized deformation corridor over 1,000m (up to 200m wide) consisting of multiple discrete zones of deformed volcanic rocks and shear parallel quartz veins. This corridor is open along strike and at depth.

Highlights include 2.36 g/t Au and 8.00 g/t Ag in sample F809074 and 0.927 g/t Au and 2.08 g/t Ag in sample F809077 (Figure 1). These samples enrich the corridor providing additional mineralization complementing the existing high-grade gold-silver mineralization from surface.

We have also confirmed at surface a 1m wide vein in the field (assays pending) at the eastern extension of the project. Alcona Area is drill ready with over 1km strike extension at surface. Visible Galena, chalcopyrite and pyrite.

New Millennium: At least two mineralized deformation corridors consisting of multiple discrete zones of deformed volcanic rocks and shear parallel quartz veins.

Grab samples from the New Millennium T99-3 and T99-5 trenches along the Central Vein (Figure 3):

F809099 12.4 g/t and 46.7 g/t Ag
F809123 1.54 g/t Au and 0.61 g/t Ag
F809122 0.636 g/t Au and 2.72 g/t Ag
F809121 2.82 g/t Au and 12.05 g/t Ag
F809095 0.784g/t and 3.14 g/t Ag

Exploration to date have These results confirmed the mineralization along the central vein system and has highlighted areas of higher grade which have will helped guide the proposed drill plan at New Millennium.

Corporate Update

The Company also announces that it has granted incentive stock options pursuant to its stock option plan to directors, officers and consultants to purchase up to an aggregate of 2,490,000 common shares of the Company. The stock options are exercisable at a price of C$0.09 per common share and expire three years from the date of grant.

Moretti Area: Mineralized deformation corridor over 2,500m consisting of discrete zones of deformed volcanic rocks and shear parallel quartz veins ranging from cm to meter scale. New Logging activities in the north eastern portion of the Property allow for improved access, ideal for prospecting and drilling over more than five historic mineral occurrences on the property inclusive of the advanced target, Moretti.

At the north vein prospect, a large, well exposed (to the NE-trending Moretti shear) vein was channeled in 2022 (See NR November 29, 2022) along strike to assess the bulk gold tenor of that vein and confirm historical sample results. The 2023 Exploration Team continued indicated channel sampling incomplete from last year’s program. Highlights include (total length):

CH23-002 (2m) including 15.70 g/t Au and 2.01 g/t Ag over 1m and 4.72 g/t Au and 0.08 g/t Ag over 1m
CH23-003 (4m) including 26.20 g/t Au and 2.18 g/t Ag over 1m and 10.05 g/t Au and 0.13 g/t Ag over 1m

Including internal dilution with no cutoff applied
The results compare well with historical sampling.
High-grade gold samples typically exhibit low Ag/Au ratios, in contrast to those from the Alcona area.
