WESTMOUNT CONFIRMS MULTIPLE PEGMATITE OUTCROPPINGS - KABA PROPERTY

Westmount Minerals Corp. has released its summer reconnaissance and sampling program results at the Kaba lithium property in Northwestern Ontario. Multiple pegmatite outcroppings containing rare metals and associated lithium mineral indicators have been discovered during the initial program.

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 parts per million.

David Tafel, chief executive officer 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 70 metres long by 50 metres wide. Generally, the pegmatites are coarse grained and are 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. The sample returning a value of 1,320 ppm rubidium also showed a potassium/rubidium ratio of 58. This was the sample with significant muscovite and tourmaline, located within a promising southern priority area.

The known Georgia Lake lithium pegmatite field is located just west of the property. Within the pegmatite field, Rock Tech Lithium Inc. has completed a prefeasibility study (see news release dated Nov. 16, 2022) stating its Georgia Lake property has 10.6 million tonnes of indicated mineral resources and 4.22 million tonnes of inferred mineral resources (see news release dated March 7, 2023). Other companies with lithium mineralization prospects include Imagine Lithium Inc. and Ultra Lithium Inc.

About Westmount Minerals Corp.

Westmount is focused on mineral exploration in the Americas and is well positioned in the emerging world-class critical mineral district of Northwestern Ontario. The 3,486-hectare Kaba lithium property is located in the Georgia Lake lithium pegmatite region, in close proximity to Rock Tech Lithium. Multiple pegmatite showings have been documented and mapped on the property.

Additionally, Westmount can earn a 100-per-cent interest in the 5,002-hectare, lithium-pegmatite-bearing Otatakan and Pilot East lithium properties located near Ear Falls, Ont. The properties are just south of Green Technology Metals' (Australian Securities Exchange listed) expanding Root deposit.

The company has also advanced the Douay East gold property located within the greater Abitibi greenstone belt region in Quebec to the drill-ready stage.
