Class 1 samples 1.11 g/t Pd+Pt+Au at River Valley

Mr. David Fitch reports CLASS 1 NICKEL CONFIRMS 3+ KM PGE-TREND AND SAMPLES 1.11 G/T PD+PT+AU AT THE RIVER VALLEY PGE-CU-NI PROJECT, ONTARIO, CANADA Class 1 Nickel and Technologies Ltd. has released results from its recently completed 2025 prospecting and ground-truthing campaign over its River Valley platinum-group-element-copper-nickel project, located about 65 kilometres northeast of the city of Sudbury, Ont., Canada. The RV project covers approximately 2,916 hectares and hosts several kilometres of highly prospective geology with known platinum-group-element-bearing sulphide mineralization. This mineralization is categorized as contact-style PGE-copper-nickel and is hosted by the River Valley intrusion. The RV project lies immediately south of, and within the same intrusive complex as, the advanced River Valley palladium project being developed by New Age Metals Inc. A total of 73 rock grab samples were collected from outcrop and sent for multielement assay (grab samples are inherently selective and serve to prove the presence of mineralization only). Highlights from the sampling program include: 0.96 per cent copper, 0.17 per cent nickel, 0.47 gram per tonne 3E (palladium plus platinum plus gold) and 3.28 grams per tonne silver; 0.54 per cent Cu, 0.19 g/t 3E and 0.54 g/t silver; 1.11 g/t 3E and 0.77 g/t Ag; Several new targets were generated for follow-up with ground geophysics and a potential drilling campaign. Of the 73 rock grab samples, 11 samples (inclusion-bearing and melagabbro) returned assays ranging from 0.26 to 1.11 g/t 3E, 0.04 to 0.96 per cent Cu and 0.02 per cent to 0.17 per cent Ni. A surface geophysics program is being planned for the North PGE trend and the Crerar PGE trend. David Fitch, chief executive officer of Class 1 Nickel, commented: "Results from this surface sampling program, combined with results from the VTEM airborne geophysical survey completed earlier this year, along what we know from historical exploration and drilling done on the property, give us confidence to continue with additional exploration in the target areas, including the Crerar PGE trend, in order to plan and complete a drilling program in the near future." In July, 2025, the company completed a field sampling and ground-truthing survey across the project. Objectives of this program were to sample and map bedrock across the property to generate targets for a future drilling program. Several VTEM conductors and geophysical picks identified from the spring VTEM survey (see news release dated May 27, 2025) were visited during this campaign. River Valley PGE-Cu-Ni project The RV project, covering known contact-style PGE-Cu-Ni sulphide mineralization (Crerar PGE trend) in the southern part of the intrusion, provides PGE-focused exploration upside to the company's portfolio, as well as exposure to critical minerals, PGE, copper and nickel. The RV project is underlain by gabbroic to anorthositic rocks of the Paleoproterozoic RVI with a focus on targeting the productive marginal and inclusion-bearing zones. Noteworthy historical exploration on the property includes a diamond drill program completed in 2001 by Mustang Minerals Corp., which targeted the area of the Crerar PGE trend. Highlights of Pd+Pt+Au grades (3E) from this historical 2001 program include: 0.30 g/t 3E over 6.80 metres and 0.31 g/t 3E over 5.45 metres in hole MRS-01-1; 0.58 g/t 3E over 7.00 metres in hole MRS-01-6; 0.61 g/t 3E over 3.00 metres in hole MRS-01-7; 2.26 g/t 3E over 1.50 metres and 0.82 g/t 3E over 7.00 metres in hole MRS-01-2; 0.58 g/t 3E over three metres in hole MRS-01-9; and 0.51 g/t 3E over nine metres in hole MRS-01-10.

About Class 1 Nickel and Technologies Ltd. Class 1 is a mineral resource company primarily focused on the exploration and development of its 100-per-cent-owned komatiite-hosted nickel sulphide projects: the Alexo-Dundonald project near Timmins, Ont. (four nickel sulphide deposits), and the Somanike project, near Val d'Or, Que. (includes the historical Marbridge Ni-Cu mine). Both projects comprise extensive property packages covering past-producing nickel mines, offering excellent exploration upside and near-term production opportunities. The company holds a 100-per-cent interest in its River Valley PGE project located about 65 kilometres northeast of the city of Sudbury, the world's largest and longest operating nickel-copper-cobalt-PGE mining camp (see Class 1 news release dated Dec. 13, 2023). Outside of the River Valley PGE project, Class 1 is advancing its Alexo-Dundonald project toward near-term production and at the same time continuing brownfield and greenfield exploration on its large property package to aggregate additional nickel resources. The A-D project sits on a 14-plus-kilometre strike length, folded komatiite unit containing four nickel-copper-cobalt-PGE mineral resources plus numerous underexplored sulphide occurrences. Decades of successful capital expenditure and investment into the project have resulted in the discovery and delineation of the four mineral resources, but the greater property area remains underexplored. The A-D project was previously mined (about 2005) through a direct shipping model, and the company is investigating the possibility of a preliminary economic assessment study to determine the best path forward.
