Lancaster Resources Field Trip Results from Lake Cargelligo Gold Project

Vancouver, British Columbia--(Newsfile Corp. - January 21, 2026) - Lancaster Resources Inc. (CSE: LCR) (OTC Pink: LANRF) (FSE: 6UF0) ("Lancaster" or the "Company") is pleased to report results from recent field work at its 100% owned Lake Cargelligo Gold Project in New South Wales, Australia.

Field work undertaken in December 2025 included meetings with landowners to advance access agreements, and geological mapping and rock chip sampling of new prospect areas that were guided by interpretation of LiDAR data, as previously announced.

Field Trip Highlights

• Landowner Agreements Advancing: Multiple landowners met in person, with significant progress made for access agreements to facilitate geophysical and drilling programs.

• Extensive Strike Length: 75km of prospective granite-sedimentary contact strike length within Lancaster's tenure, which is largely unexplored, with recent field work undertaken at the Greater Josephine Moulder, Greater Avoca, and LiDAR Targets 1-4 (LT1-4).

• Multiple Vein Systems: Extensive areas of newly mapped veins at the Greater Avoca and Josephine Moulder North prospects, where limited historical rock-chip sampling returned up to 3.66 g/t Au and 1.6 g/t Au respectively¹ as well as encouraging geological observations from the accessible portions of LT1.

• New Vein System Discovered at Greater Avoca: Follow up mapping of Company reconnaissance rock chip sampling in August 2025 has identified a large new vein system subcropping-outcropping over >1.25km of strike that was not previously recognized.

• Josephine Moulder Expands Northwards: Follow up reconnaissance of historical geochemical Au-Ag-Te-Bi-As-Mo-Sb auger anomalies² identified evidence of widespread quartz veining and hydrothermal alteration, significantly expanding the Greater Josephine Moulder prospect, where a geochemical footprint now extends over >2km of strike.

• Refined Exploration Programs Developing: Multiple, high-impact exploration programs are being considered across the project to include further geological mapping and sampling, detailed airborne magnetic surveying and expanded LiDAR coverage, ground-based induced polarization surveying, resource drilling at Josephine Moulder, and reconnaissance drilling at other targets.
