Silicon Metals Corp. Commences 2025 Field Work and Reports High Purity Results

Vancouver, British Columbia--(Newsfile Corp. - June 4, 2025) - SILICON METALS CORP. (CSE: SI) (FSE: X6U) (OTC Pink: SLCNF) ("Silicon Metals" or the "Company") is pleased to announce the start of fieldwork at its Ptarmigan Project (the "Project" or the "Property), located ~130 km from Prince George, BC, following promising Q4 2024 high-purity sampling results.

The Company recently completed a high-definition airborne LiDAR survey, conducted by McElhanney Ltd., to generate a 3D topographic model of the Property. This will support modeling of the high-purity quartzite formations, which appear as prominent northwest-southeast trending ridges.

In late 2024, 225 samples (184 quartzite and 41 country rock) were collected and analyzed by Bureau Veritas. Results showed:

• 48% of quartzite samples exceeded 99% SiO₂

• 8% exceeded 99.9% SiO₂

• Average purity: 98.49% SiO₂

Main impurities included Al₂O₃ (0.84%), Fe₂O₃ (0.33%), K₂O (0.17%), and TiO₂ (0.10%). Samples were prepared using ceramic pulverisers and analyzed via XRF fusion to minimize contamination, though some metal traces from tools are expected. The reader is cautioned that grab samples are selected samples and may not represent true underlying mineralization.

COO Raymond Wladichuk, stated: "We're excited to build on 2024's success. With a stronger technical team and strategic plan, we're ready to advance the Ptarmigan Project."

Procedures

Rock grab, chip, and channel samples were collected from in-situ outcrops. Channel samples were cut using a handheld masonry saw with a diamond blade and were collected in 2 meter intervals for a total of 24 meters across two separate channel cuts. Chip samples were taken from an exposed bluff in a quarry and were collected in 5 meter intervals for a total of 30 contiguous meters. Samples were placed in poly ore bags with unique sample IDs and sealed with zip ties. Rock descriptions, sample location, and sample details were recorded for each sample. Samples were shipped to Bureau Veritas labs in Vancouver, BC, an independent certified laboratory, via Bandstra Transportation Systems; in-house chain of custody and sample security measures were implemented for all sample shipments. Samples were crushed until 70% passed through 10 mesh and a further 250 grams was pulverized (PRP70-250). Pulverized material was analyzed via X-ray fluorescence on a fused disc with Si02 detection limits of 0.01%
