Legacy Gold Commences Drilling on the Baner Gold Mine Property in Central Idaho

Calgary, Alberta--(Newsfile Corp. - August 21, 2025) - Legacy Gold Mines Ltd. (TSXV: LEGY) (the "Company" or "Legacy Gold") announces that drilling is underway on the Baner property (the "Baner Gold Mine Property") to test the views of Legacy Gold's geologists that the zones of gold mineralization at the Baner Gold Mine Property are more commercially meaningful than previously thought.

Located in Idaho County, Idaho, USA, the Baner Gold Mine Property sits within the historic Orogrande Gold Mining District that has hosted numerous historic gold mines since Idaho's first gold rush in the late 1800's (see Figure 1 — Property Location Map). This 2025 drill program is expected to consist of approximately 4,572 metres (15,000 feet) of reverse circulation drilling (RC) focused on the previously drilled "Main Zone" (see Figure 2 — Plan View — 2025 Proposed Drilling).

"Legacy Gold's geologists have optimized the targets to best drill and test their views of the shape and potential of previously drilled mineralized gold zones on the Baner Gold Mine Property," said Brian Hinchcliffe, Legacy Gold, CEO. "Acquiring the option for Baner last year and commencing the first drill program this fall, the timing of Legacy Gold being launched alongside the momentum in the gold market has worked out well so far."

"With the successful prospecting and surface sampling results conducted since we acquired the option for the Baner Gold Mine Property from Champion Electric in Q4 last year, we are very excited to commence our first drilling campaign on the property. This program will look to follow-up on previous drilling success, to extend the strike length and expand zones of mineralization within the Main Zone," said Mike Sutton, Legacy Gold, VP Exploration.

Legacy Gold 2025 Drill Program

This drilling program will focus on the Main Zone, where previous drilling by Champion Electric encountered high-grade intercepts as highlighted below:

• 8.7 g/t Au over 6.3m (21ft), including 146.7 g/t Au over 0.3m (0.98ft) (ICG2018-08);
• 66.0 g/t Au over 4.8m (16ft) (ICG2018-15);
• 5.39 g/t Au over 5.1m (17ft), including 24.27 g/t Au over 0.5m (1.64ft) (ICG2018-16); and
• 20.84 g/t Au over 12.0m (39ft), including 48.98 g/t Au over 4.5m (14.76ft) (ICG2018-13).

See the Technical Report (defined below) for additional information.

Drilling will test for continuity of high-grade and wide low-grade zones of mineralization in a flatter dip scenario along the 1km section of the Orogrande structure within the Main Zone. The Orogrande structure is host to numerous gold deposits and past producing gold mines.

The drill program will look to follow-up on previous drilling but assumes that greater potential width to the mineralized zones can be captured by angling the drill hole direction differently. The goal will be to extend the strike length and expand zones of mineralization within the Main Zone. Drilling highlights include:

• Limited drilling conducted returned numerous high-grade intercepts that warrant follow-up.
• There are two major NS structures that host gold mineralization in the area of the Main Zone, along the Orogrande shear zone.
• Drilling will test a new geological interpretation which could open up the entire zone of mineralization.
• Surface sampling returned continuous highly anomalous values which will be used for future target validation.
