Legacy Gold Mines Ltd. (TSX-V: LEGY) reports assay results from the first two holes of the Phase 1 core drilling portion of its 2026 drill program at the Baner Gold Mine Property in Idaho County, Idaho, USA. The Company expects the Phase 1 core drilling portion of the drill program to be completed this week. The Phase 2 reverse circulation drilling portion, which is testing both the previously drilled Main Zone and other target areas, is well underway.

“It is important not to lose sight of the principal objective of this year’s drilling, which is to prove that the mineralization extends uphill such that the Exploration Target is realized,” said Mike Sutton, Vice-President, Geology of Legacy Gold. “To date, we’ve done that and have, in fact, extended the mineralization beyond the area contemplated by the Exploration Target to the south.”

The first hole, LG26-009, intersected five mineralized zones and extended mineralization up to 150m (492ft) south of the nearest previous intersection. The 150m (492ft) offset intersection graded 2.9 g/t Au and 41.8 g/t Ag over 3.6m (11.8ft) and is thought to represent the north-south extension of mineralization in the Main Zone. The same hole also intersected 0.43 g/t Au over 16.9m (55.4ft) from 6.1m (20ft) downhole (2.5m or 8ft vertical), which is thought to represent the east-west trending Baner vein mineralization.

Results from hole LG26-015 filled in a 150m (492ft) gap at the northern end of the Baner Main Zone and returned four (4) mineralized zones, with the two best zones, located mid-way among the four, grading 1.1 g/t Au over 12.4m (40.7ft) and 0.42 g/t Au over 14.5m (47.4ft). Of utmost importance, the oriented core from holes LG26-015 and LG26-010 (assays pending) proved the premise underlying the Exploration Target set out below – that the mineralization is flat and east-dipping. The holes were not drilled in numerical order because drilling was limited to pads permitted in 2025 until the 2026 drill permit was received.

The first phase of the 2026 drill program was designed to strategically core drill the first 12,000ft (3,658m), followed by up to 28,000ft (8,536m) of RC drilling. This program follows up on the successful 2025 results by targeting both the Main and Northeast Zones, as well as new exploration targets to the northwest indicated by large gold-in-soil anomalies coincident with geophysical conductors and similar magnetic highs as are in the Main Zone.

To date, ten core holes have been drilled, with one more core hole pending: one exploration hole to the west; two holes at the south end of the Main Zone and Baner Zones; three holes up the hill in the western portion of the Main Zone; three holes at the north end of the Main Zone; and one hole in the west portion of the Northeast Zone. The final hole is also located in the Northeast Zone.

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 uphill 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 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, IP 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, 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.

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. 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 the 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 kilometers 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 that 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 uphill (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.

Geology and Mineralization

The belt of mineralization that traces through the Elk City and Orogrande mining districts is known as the Orogrande Shear Zone, and is estimated to be between 100-200m wide, with a general NNE trend. Gold mineralization occurs along this zone in numerous prospects and small historic mines. Most of the mineralization appears to be along Riedel shear structures that cross over between two bounding major north-south structures along the Orogrande Shear Zone. In general, higher grade historical mining was undertaken on narrow zones of strong sericite-silica-carbonate alteration and quartz veins. Intrusion-related structurally controlled mineralization has been suggested previously. At the Property, the predominant host rock is quartzite, with some biotite gneiss also present.
