Calgary, Alberta--(Newsfile Corp. - June 3, 2026) - Legacy Gold Mines Ltd. (TSXV: LEGY) (the "Company" or "Legacy Gold") reports that, as planned, a second diamond drill arrived on the Baner Gold Mine Property in Idaho County, Idaho, USA ("Baner Property") and commenced drilling over the weekend of May 30^th. The Company's 2026 exploration plan is for the first 12,000 feet (3,658 meters) to be core drilled, after which reverse circulation ("RC") drilling will take over to drill the remaining 28,000 feet (8,536 meters) of the program in the months of July through September, subject to receipt of required permits and approvals. This program follows up on the successful 2025 results by targeting the Main and NE Zones, as well as new exploration targets indicated by large gold in soil anomalies co-incident with geophysical conductors and similar magnetic highs as are in the Main Zone.

In an effort to advance production conceptualization for the Baner Property, alongside the commencement of drilling, the Company has entered into a contract with RDI - a Division of McCarl's Technical Services, LLC - for Metallurgical and Deportment studies that will follow up on previous work carried out by RDI on the Baner Property. The Company has also entered into a contract with Expert Geophysics Limited for airborne geophysical MT (Magnetotellurics) and magnetic surveys over the entire property.

"Central Idaho is an exciting new center for US gold production following decades of exploration by Canadian Companies and the Oro Grande District - where the Baner property sits - will benefit from this momentum," said Brian Hinchcliffe, Chairman and CEO of Legacy Gold. "Most of the historic gold mines on the Baner are in the Main Zone but our geologists are keen to use today's high tech exploration tools to expand exploration and drilling to the Northwest, Northeast and to the South of the Main Zone as the 2026 exploration program advances."

Magnetotellurics is a passive electromagnetic system designed to measure resistivity/conductivity of the Earth and is especially useful for penetrating to deeper levels than comparable geophysical methods. The aim of the survey is to identify conductors beneath the water table that may represent the sulphide equivalents of the Baner Property oxide mineralization. The idea is to see if there are significant concentrations of sulphides, suggesting best places to drill oxides above (and possibly finding the depth of potential intrusive fluid sources for the overlying gold). The 339 line kms survey will be conducted in June by Expert Geophysics Limited and flown at 100m line spacing using their MobileMT system. The survey will include airborne magnetics. The results will help inform targeting for follow-up drilling planned for later in the year.

DRILLING TARGETS

Main Zone

Drilling in 2025 intersected very wide zones such as new assays of 0.55 g/t Au over 187.5m (615ft) in the middle, 0.52 g/t Au over 108.2m (355ft) in the south, and new assays of 0.57 g/t Au over 64.0m (210ft) in the north (see the Company's March 17, 2026 press release). The deposit remains open in all directions. Drilling in 2026 will primarily drill up-hill from the drilling to date in the Main Zone to follow the interpreted flatter east-dipping veins to surface. On the south end of the north-south Main Zone are the Baner Zones. They are east-west trending and have up to 20 historical adits and shafts along them for 3,000ft. Thirty-five (35) holes are planned in this area (7 core holes and 28 RC holes).

NE Zone

The NE Zone is separated by a 400m undrilled gap from the Main Zone. It has limited drilling from 2020 by previous operators but contains multiple mineralized zones of similar grades/widths like the Main Zone. Together with the Main Zone, these are the areas that the initial exploration target at the Baner Property is based on and which Legacy Gold is aggressively drilling in 2026 in order to delineate a mineral resource. Ten (10) holes are planned in this NE zone (2 core holes and 8 RC holes).

NW Zone

The NW Zone is located 1700m NW of the Main Zone along similar geophysical and geochemical anomalies as the Main Zone. Similar magnetic highs, I.P. conductors, and high gold in soil anomalies (up to 1.0 g/t gold) are located along this NW trend as is found at the Main Zone- and yet it has never been drilled. The closest drill hole is the step-out hole #6 drilled in 2025 that returned a continuous intersection of 0.57 g/t Au over 64.0m (210ft) from surface. It was located approximately 136m northwest of the other nearest drilling. Another zone that will be drilled is located to the west and is identified by a 530m long north-south soil anomaly with a high of 1.1 g/t. Altogether, six (6) holes are planned in the NW zone (4 core holes and 2 RC holes).

The 2025 surface drill program at the Baner Property focused on testing for continuity of high-grade and wide low-grade zones of mineralization with a new flatter-dipping interpretation of zones controlled by major structures that acted as conduits for gold bearing fluids. This would result in better continuity of mineralization, the potential resource can be far greater, and the strip ratio in a production scenario would be greatly decreased. The Company is targeting high grade mineralization that is amenable to open pit, heap-leach development.

The planned drilling described above forms part of the Company's 2026 exploration program and remains subject to receipt of required permits and approvals, as applicable.

Exploration Target

Results from the recent 2025 drilling and previous drilling and exploration have supported the initial exploration target at the Baner Property of approximately 50.3 million to 55.3 million tonnes, at average grades ranging from approximately 0.72 g/t Au to 0.91 g/t Au (the "Exploration Target"). Furthermore, this initial Exploration Target was estimated prior to the receipt of the new assays reported by the Company in March 2026, which represent approximately 30% of the 2025 drill program. The potential quantity and grades of the Exploration Target are conceptual in nature. There has been insufficient exploration to define a mineral resource and it is uncertain whether further exploration will result in the target being delineated as a mineral resource. The Exploration Target does not represent a mineral resource estimate and has not been prepared in accordance with NI 43-101 mineral resource categories. See "Basis for Initial Exploration Target" below for additional information.

Basis for Initial Exploration Target

This initial Exploration Target was estimated before the new assays reported by the Company in March 2026 were received. It is limited to 1,000m for the Main Zone (plus 500m at Baner Mine trend), and 370m for the NW Zone within 1,370m of the Orogrande structure. The initial Exploration Target excludes the adjacent soil anomalies along strike which indicate significant room to grow. This preliminary target also excludes other targets on the Baner Property that have overlapping geophysical magnetic and conductor/soil/structural anomalies similar to where the drilling has taken place to date. The anomalous soils extend another 600m in the immediate area, while other soil anomalies suggest a further 2,200m - if drilling in those areas intersects similar criteria, the Exploration Target would increase.

The conceptual volumetric calculations are derived from sectional interpretation and geological modelling. The geological information was collected from a total of 46 drill holes for 10,459m drilled over 2.3 kilometres of strike by Legacy Gold in 2025 (RC) and Idaho Champion (core) in 2018 and 2020.

The gold grade range of the Exploration Target has been calculated from the significant number of drill intercepts returned from the 46 holes completed to date. There are 114 intersections which are above 0.2 g/t cut-off. A minimum width of 5m was used (5m benches). The volume range (tonnages) of the Exploration Target is defined by the drilling completed combined with the evidence up-dip given by similar grade soils to where drilling has taken place.

Intersections were weighted averaged for each of 10 sections, with strike lengths calculated from mid-point to midpoint between sections. There is an average of 3.8 zones per section. The dip lengths were measured up the hill where gold in soils suggests gold in the underlying rock. This evidence was proven in 2025 at the only set-up drilled up-hill (with gold intersections at surface and all the way down dip for at least 290m). Several smaller sections were created where RC returned significantly wider intersections but at lower grade to core drilling. The average dip length for the 10 sections is 230m. True widths were used where the interpretation suggested an obvious change was required- most drilling is thought to be close to true width otherwise. The weighted average sectional grade gives 0.72 g/t, with the two highest being 1.51 g/t and 1.07 g/t.

Using a simple weighted average of all 114 intersections gives 0.91 g/t over 12.8m. An assumed bulk density was used of 2.73 t/m3- consistent with quartzite-hosted gold systems. Initial metallurgical cyanide leach testing gave 87.1%-93.2%; at 4km north, Bema undertook open pit mining and heap leaching (fully permitted) at Buffalo Gulch in the early 1990's which was 95% permitted again in 2023 by Endomines. The Company cautions that mineralization and metallurgical results at Buffalo Gulch may not be indicative of mineralization or metallurgical results at the Baner Property.

The Company intends to conduct additional drilling and technical studies to evaluate whether sufficient data may be obtained to support a future mineral resource estimate.
