Linear Minerals Assayed 21.10 Percent Copper in Surface Samples at the Lac Coulombe Property, Quebec

VANCOUVER, BC / ACCESS Newswire / October 29, 2025 / Linear Minerals Corp. (CSE:LINE)(OTCQB:LINMF)(WKN:A2J C89) ("Linear" or the "Company") is pleased to announce results from our initial exploration work at the Lac Coulombe Property in Quebec, Canada. Assays revealed copper values ranging from less than 0.5 parts per million (ppm) to 211,000 ppm (21.10% Cu), along with anomalous gold and silver values (see Table 2 for details).

Highlights:

  • Copper (Cu) Results: Samples returned values between 0.5 ppm to 211,000 ppm (21.10% Cu). The highest copper values were from the Toupin Showing (see Figure 2 for location of the many historical showings on the Property), where six samples returned values between 4.6% to 21.10% Cu. The Mount Louise Showing had one sample at 0.8% Cu, while one sample (1157406) from the Lac Coulombe Showing returned 0.21% Cu.

  • Gold (Au) Results: Anomalous gold values were associated with high copper samples at the Toupin Showing. A sample from Lac Coulombe Showing assayed at 1.518 ppm Au, with another sample from the same area returning 0.114 ppm Au. Gold values overall ranged from <0.001 ppm to 1.518 ppm.

  • Silver (Ag) Results: Silver values ranged from 0.01 ppm to 48.2 ppm, with the highest values from the Toupin Showing (48.2 ppm). One sample from the Lac Coulombe Showing returned 9.53 ppm Ag.

  • Nickel (Ni) Results: Nickel values ranged from 1.8 ppm to 1,730 ppm. A single sample from the historical Laurier Juteau Ni Showing recorded 1,730 ppm Ni.

The Company is also pleased to share the news that it has received ATI (Impact causing Exploration Work) permit for the Property to carry out trenching and drilling work in the high-grade surface sampling areas.

The Company plans to conduct follow-up exploration to further assess both the high-grade copper showings and the hydrogen potential of the Lac Coulombe Property.

Sample Preparation and Analysis

The Company conducted a field program that included prospecting, geological mapping, and sampling. The objective was to locate historical showings and validate sampling results from previous operators. A total of 29 grab and channel-cut samples, including two field duplicates, were collected. Samples were bagged and tagged following best practices before being sent to AGAT Laboratories in Val-d'Or, QC, for sample preparation and analysis. AGAT conducted Gold by Fire Assay, 4-acid digestion - Metals Package, and overlimit package analyses (see Table below for details). AGAT is an independent, accredited laboratory with ISO certification for certain tests.
