Vancouver, British Columbia--(Newsfile Corp. - November 5, 2026) - Catalyst One Exploration Corp. (TSXV: CATX) (OTC Pink: CTXCF) (the "Company") is pleased to announce that it has entered into a property purchase agreement dated November 4, 2026 (the "Purchase Agreement") with LIRECA Resources Inc. (the "Vendor"), pursuant to which the Company has agreed to acquire an undivided 100% legal and beneficial interest in the BC REE Property, a rare earth element ("REE") exploration property located approximately 85 kilometres northeast of Prince George, British Columbia (the "Property"), for aggregate cash and share consideration of $870,000, together with the grant of a 3% net smelter returns royalty, as described below (the "Transaction"). The Vendor is at arm's length to the Company.
"We are excited to add the BC REE property to our portfolio. The global market for rare earth elements is undergoing a massive, structural transformation, evolving from a clean-energy and electric vehicle story into the bedrock of physical AI, robotics, and advanced technology infrastructure," Catalyst One CEO Michael Ruggles commented.
The Property
The Property consists of eight contiguous mineral claims covering 6,164 hectares, centred approximately 35 kilometres east of the community of Bear Lake and 85 kilometres northeast of Prince George, British Columbia. The Property is accessed from Highway 97 through Bear Lake and a network of forest service roads, and is located in close proximity to hydroelectric power lines and railway lines. The southern boundary of the claims lies approximately 1,200 metres north of Defense Metals Corp.'s proposed Wicheeda open pit mine (NI 43-101 Technical Report, Wicheeda Rare Earths Project PFS, dated April 4, 2025).

The Property is being explored for REE and niobium mineralization. The area is underlain by upper Cambrian to lower Ordovician sedimentary rocks of the Kechika Group, comprising siltstone, limestone, marble, argillite and calcareous rocks, which are intruded by the Wicheeda intrusive suite. This is the same suite of rocks that host the Wicheeda deposit. The strata strike between 120° and 140° and dip steeply to the northeast and southwest.
2025 Exploration Program
An exploration program was completed on the Property in June and September 2025, consisting of a detailed heliborne magnetic and radiometric survey and soil and rock sampling. The survey identified a number of geophysical targets that may represent carbonatite intrusions. Due to limited access and time constraints, two of these targets, together with an exposed road cut, were followed up with geochemical sampling.
A total of 36 soil samples were collected. Soil sample W25T020, collected from geophysical target T1, returned the highest values of the program, with 0.869% total rare earth oxides ("TREO") and 478 ppm niobium. Two rock samples collected from the road cut returned background values. The results of the program are documented in an assessment report dated March 5, 2026.
Recommended follow-up work includes resampling the W25T020 site to confirm reproducibility, investigating rock fragments in the overburden, hand trenching to expose bedrock at this location, and soil sampling of additional geophysical targets.
Readers are cautioned that soil geochemical results are not necessarily representative of mineralization in the underlying bedrock, and that mineralization on adjacent or nearby properties, including the Wicheeda REE deposit, is not indicative of mineralization on the Property.
