ritage Mining Announces Corporate and Exploration Update

VANCOUVER, BC, May 23, 2023 – Heritage Mining Ltd. (CSE: HML FRA:Y66) (“ Heritage” or

the “Company”) is pleased announce significant advancements in the first few weeks of its fully permitted

Phase 1 exploration drilling pr ogram at the flagship Drayton – Black Lake project (the “Project”) (Figure 1),

located near Sioux Lookout, Ontario. The Project is located within Eagle-Wabigoon-Manitou greenstone belt

of the Wabigoon Subprovince, which also hosts the Treasury Metals Inc. (TSE:TML) Goliath-Goldlund

deposits.

Exploration Update:

New Millennium Area (Never Drilled): At least three mineralized

deformation corridors consisting of multiple

discrete zones of deformed volcanic rocks and shear para llel quartz veins. A 5m wide orogenic load gold style

sheeted quartz veins identified in the hanging and foot wall was identified on the first day of mapping at the

Project. Pyrite, Chalcopyrite, and Galena observed in the vein system, similar to New Millennium veins sampled

to the north. Grab sample assays pending (Figure 2). The Company has also secured a contractor to clear a trail

to the New Millennium Area for proposed drilling by month’s end, weather permitting.

Peter Schloo, President, CEO and Director commented, “A fantastic find on the team’s first day at New

Millennium and the largest vein in the area to date. Leveraging our local relationships, we have secured a

permitted trail ahead of schedule. The trail will provide for better access thereby increasing operational

efficiency and the number of available drill targets. We will continue to work with all stake holders to advance

the area in a collaborative manner inclusive of all stakeholders.”

Alcona Area: Mineralized deformation corridor over 1,000 m (up to 200 m wide) consisting of multiple discrete

zones of deformed volcanic rocks and shear parallel quartz veins. The team confirmed significant galena, pyrite,

chalcopyrite and sphalerite associated with a 15m corridor of primary and secondary quartz veins at the Powerline

Prospect (never drilled) which has been upgraded from proposed to drill ready-status (Figure 3).

Peter Schloo, President, CEO and Director commented, “The Powerline Prospect is a great window into the

Alcona Area. This extension has never been drilled and is now a priority drill target with the potential of

extending strike at depth. The access is fantastic, with logging active in the area, providing additional

exploration upside.”

Moretti Area: Mineralized deformation corridor over 2,500 m 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.

Peter Schloo, President, CEO and Director commented, “Recent logging activities is fantastic for our project.

This increases the probability of new discovery and optimi zes capital and operational efficiency pertaining to

prospecting and drilling access. There is even a logging road going right past where we want to drill at Moretti.

Simply put, We spend less time and capital getting there, and more time being there, fantastic.”

Corporate Update:

In less than two weeks from mobilization, the Comp any has secured vital equipment for Phase 1 mapping and

exploration and coreshack facilities (Figure 5).
