Report Highlights:

• Summer program comprised inaugural mapping and sampling of abundant pegmatite occurrences.

• Mineralized pegmatite contains white micas, garnet and tourmaline.

• Geochemical analyses show good potential for lithium mineralization with eight samples returning lithium values greater than 50 ppm.

Vancouver, British Columbia--(Newsfile Corp. - November 23, 2023) - Westmount Minerals Corp. (CSE: WMC) ("Westmount" or the "Company") announces its summer reconnaissance and sampling program results at the Kaba Lithium Property (the "Property") in Northwestern Ontario. Multiple pegmatite outcroppings containing rare metals and associated lithium mineral indicators have been discovered during the initial program.

David Tafel, CEO and Director commented: "Our geological team has confirmed the presence of multiple pegmatite outcroppings as well as lithium indicator minerals. Results from this limited sampling program are encouraging and have identified priority pegmatite focus areas for a follow-on site visit. The results also underscore the Kaba property's strategic location in the Georgia Lake pegmatite area."

The largest pegmatite outcropping discovered to date measured approximately 70m long x 50m wide. Generally, the pegmatites are coarse-grained and composed of quartz and feldspar. Contained mineralization is evidenced by the presence of large "books" of white mica and biotite, red garnets and tourmaline. Multiple sample assay results have revealed interesting values of Boron (up to 670 ppm), Barium (up to 1,750 ppm) and Rubidium (up to 1,320 ppm). In addition, many occurrences displayed very good fractionation and fractionation trends with low ratios of potassium/rubidium. The potassium/rubidium ratio often has a strong correlation to Lithium-enrichment. Priority areas for follow-up sampling have been identified in Map 1. The sample returning a value of 1320 Rb also showed a K/Rb ratio of 58. This was the sample with significant muscovite and tourmaline, located within a promising southern priority area.

The well-known Georgia Lake Lithium-pegmatite field is located just west of the Property. Within the pegmatite field, Rock Tech Lithium Inc. has completed a Pre-Feasibility Study (NR-November 16, 2022) stating its Georgia Lake property has 10.6 million tonnes (mt) of Indicated Mineral Resources and 4.22 mt of Inferred Mineral Resources (NR- March 7, 2023). Other companies with lithium mineralization prospects include Imagine Lithium Inc. and Ultra Lithium Inc. (Map 2)
