(TSXV:CATX) Catalyst One Exploration Corp. has entered into a property purchase agreement dated November 4, 2026, with LIRECA Resources Inc. to acquire a 100% legal and beneficial interest in the BC REE Property, a rare earth element exploration property located approximately 85 kilometres northeast of Prince George, British Columbia. The total consideration for the acquisition is $870,000, consisting of 3,800,000 common shares at a deemed price of $0.15 per share and $300,000 in cash, together with the grant of a 3% net smelter returns royalty. The BC REE Property comprises eight contiguous mineral claims covering 6,164 hectares, situated about 35 kilometres east of Bear Lake and 1,200 metres north of Defense Metals Corp.'s proposed Wicheeda open pit mine. The property is accessible via Highway 97 and forest service roads and is near hydroelectric power and railway lines. An exploration program was completed in June and September 2025, including a heliborne magnetic and radiometric survey and soil and rock sampling. A total of 36 soil samples were collected, with sample W25T020 from target T1 returning 0.869% total rare earth oxides and 478 ppm niobium; two rock samples from a road cut returned background values. The results are documented in an assessment report dated March 5, 2026. Recommended follow-up work includes resampling, hand trenching, and additional soil sampling. The 3% net smelter returns royalty will be granted to 1079170 B.C. Ltd., an affiliate of the vendor, and may be reduced to 1% in 1% increments by paying US$1,000,000 for each 1% reduction. No finder's fee is payable for the transaction. Upon completion, the vendor is expected to hold approximately 15.3% of Catalyst One's issued and outstanding shares and will become an insider under TSXV policies. The transaction is classified as a 'Reviewable Transaction' under TSXV Policy 5.3 and is subject to TSXV acceptance and customary closing conditions. The technical information in the release was prepared and approved by Chris M. Healey, P.Geo., a Qualified Person under NI 43-101. Catalyst One also owns a 100% undivided interest in the Palmetto Gold Project in Nevada, consisting of 116 unpatented mining claims totaling 2,217 acres.
