Harvest GOLD Announces Mosseau Drill Program Update; Urban Barry Regional Till Program Completed

Exploration Programs

HARVEST GOLD ANNOUNCES MOSSEAU DRILL PROGRAM UPDATE;

URBAN BARRY REGIONAL TILL PROGRAM COMPLETED

Vancouver, British Columbia / August 28, 2025 - Harvest Gold Corporation (TSXV: HVG)

(“Harvest Gold” or the “Company”) is pleased to announce that its diamond drill program at the

Mosseau Gold Project is well underway, with the first five holes successfully completed (see

Figure 3).

Drilling is proceeding smoothly in the northern part of the Mosseau property, an area distinguished

by numerous historical gold showings and prospective geological features. This northern part of

the mineralized corridor on Mosseau represents a key focus of the Company’s current program, as

it offers strong potential for new discoveries in addition to increasing the size of known zones of

mineralization across the area.

The drill program is on time and on budget. Harvest Gold would like to acknowledge the excellent

work being carried out by its contractors. First, Forage Rouillier’s team has ensured steady and

efficient drilling progress. In addition, Explo -Logik has provided a dedicated technical and

professional crew supporting field logistics, core logging, and drill core sampling. All of the

Company’s protocols and procedures are being followed, with daily drilling and core logging

progress reports provided to management, ensuring that the program continues to advance safely

and efficiently.

Harvest Gold has also successfully completed its regional till sampling program ahead of time and

below budget across its Urban -Barry property. This initiative is designed to generate new

geochemical vectors to potential gold mineralization and complements the Company’s broader

exploration strategy across its property portfolio. The purpose of the program is to evaluate Urban

Barry’s potential for blind gold occurrences through the study of gold grain dispersion in the

secondary environment.

The survey was conducted on a grid consisting of NW –SE sampling lines spaced approximately

1,000 to 1,500 metres apart and oriented perpendicular to the dominant ice flow, with individual

sampling sites located every ~250 metres (see Figure 4).

Of the 145 till samples originally planned, the Company successfully collected 137 samples, which

contained proper surficial deposit material . Most samples were taken from depths of at least one

metre, ideally below the oxidized B horizon, to reach the lodgment till. Lodgment till is a key

target because it typically contains the highest proportion of material derived from proximal up -

ice sources, including fragments potentially associated with gold mineralization.

Each sample collected consisted of approximately 10 kilograms of material free from cobbles and

pebbles, collected by hand shovel to ensure sample integrity. The Company expects the results
