Key Highlights

• All 13 drill holes in the South and North zones intersected significant

serpentinized mineralization including nickel (Ni) and magnesium (Mg)

• Drilling confirms a ~500,000 m² mineralized footprint at the Beaver South zone

• North Zone drilling confirms additional mineralization extending along a 7‑km

trend

A Growing, Multi‑Metal Discovery

The latest drilling results (holes B25-11, 12, 13) continue to outline broad intervals of nickel‑cobalt‑magnesium mineralization across a large area, reinforcing Beaver‑Lynx as a major new critical minerals system. Latest analytical results also include analyses for platinum and palladium, elements generally associated with ultramafic deposits. PGMs were encountered in both the South and North zones and are expected to be present across other drill‑defined mineralized areas.

South Zone

Drill Hole B25‑11:

145.2 m grading 0.19% Ni,0.011% Co, 0.40% Cr, 0.012g/t Pt, 0.012g/t Pd, 23.07% Mg

Drill Hole B25‑12:

116.3 m grading 0.20% Ni, 0.011% Co, 0.35% Cr, 0.010g/t Pt, 0.009 g/t Pd, 22.93% Mg,

   •  Located ~1,000 m from B25‑11, confirming extensive length of mineralized area.

North Zone

Drill Hole B25‑13:

102.1 m grading 0.17% Ni, 0.010% Co, 0.29% Cr, 0.011g/t Pt, 0.011 g/t Pd, 20.38% Mg 

2025 Beaver-Lynx Drilling Program

The 2025 drilling program at Beaver‑Lynx consisted of thirteen diamond drill holes totaling 3,361.8 meters(m). Drilling was carried out using HQ‑sized core to manage the challenging ground conditions, with NQ downsizing often required at depth where maintaining hole stability became difficult.

In the South zone, twelve holes were completed on approximately 200‑meter centers. This drilling was designed to evaluate the continuity of mineralization previously outlined by earlier programs.

A single hole was drilled in the North zone to test a new high‑priority target aimed at expanding the zone’s discovery footprint. This hole successfully intersected significant mineralization associated with strong magnetic features that extend for more than 7 kilometers along strike, further demonstrating the scale of the system.

All holes were oriented to intersect mineralization as perpendicular as possible. A Reflex instrument was used to measure for azimuth and dip deviations, however, dip readings were found to be unreliable due the high concentrations of magnetite in the rocks. Collar information for all drillholes is itemized in the following table.

A plan map illustrating the drill collar locations in relation to the magnetics in the rocks in the South zone is located in Figure 1.

The resulting grade for nickel includes both silicate and sulphide components of nickel. A secondary partial digestion technique has been developed in-house by Actlabs for Inomin to ascertain the sulphide nickel fraction only and will be utilized on all samples containing > 0.1% nickel values and will be reported on when complete.

Actlabs, located in Kamloops, BC, is ISO 17025-accredited. The relationship between Inomin and Actlabs is strictly arms-length, limited to the laboratory’s commercial supply of analytical services. QAQC protocols were followed, including the introduction of field blanks, standards, and duplicates, custody of the core, and normal QAQC laboratory protocols. Drillcore was split using a conventional manual core splitter and power saw with a representative fraction sent to the laboratory and the remainder cached on site.

Table 2 itemizes weight averaged analytical summaries for each hole. Samples were generally taken at 3 m intervals throughout the entire program.

The 2025 Beaver-Lynx exploration program was undertaken in collaboration with Sumitomo that funded the program. Sumitomo can earn an interest in the project through an earn-in and joint venture agreement with the Company. Inomin is the operator of the Beaver-Lynx project.

About Beaver‑Lynx

The 28,000‑hectare Beaver‑Lynx property is located in south‑central British Columbia, approximately 50 kilometres north of Williams Lake and adjacent to the Gibraltar mine, Canada’s second‑largest open‑pit copper operation. The project benefits from excellent infrastructure including all‑season road access, nearby hydro‑electric power, and proximity to active rail lines. The surrounding resource communities offer comprehensive services and a skilled work force.

The South and North zones represent two of several extensive mineralized areas outlined through drilling and magnetic surveys across the Beaver block. Ten kilometres to the south, the adjoining Lynx block hosts multiple targets that are comparable – and in some cases potentially larger – than those at Beaver. Together, these zones underscore the district‑scale potential of the Beaver‑Lynx project.
