Lancaster hires Resource for data work, director quits

Mr. Andrew Watson reports LANCASTER RESOURCES ENGAGES RESOURCE POTENTIALS TO REPROCESS GEOPHYSICS AND ADVANCE EXPLORATION AT LAKE CARGELLIGO GOLD PROJECT Lancaster Resources Inc. has engaged Resource Potentials Pty. Ltd., a leading Australian geophysical consulting firm, to reprocess existing geophysical data and support the design of future geophysical programs at its 100-per-cent-owned Lake Cargelligo gold project in New South Wales, Australia. The engagement includes reprocessing and interpretation of historical airborne and ground geophysical data sets to refine the geological understanding of the Lake Cargelligo area. Findings from this work will directly inform Lancaster's continuing field exploration programs, guide the design of upcoming ground and airborne surveys, and refine drilling targets for spring 2026. "Partnering with Resource Potentials strengthens our technical foundation at Lake Cargelligo," said Andrew Watson, president and chief executive officer of Lancaster Resources. "Their deep experience in Australian gold systems and geophysical interpretation will help accelerate our path toward drill-ready targets and ensure our exploration programs are data-driven and effective." Lake Cargelligo gold project Located within the highly prospective Lachlan Fold belt, the Lake Cargelligo gold project spans approximately 62,300 hectares across one granted exploration licence and one exploration licence application. Historical exploration in the area has identified multiple high-grade gold and silver occurrences through rock chip and channel sampling, as well as historical drilling. Notable historical results include up to 204 grams per tonne Au (gold) and 273 g/t Ag (silver) from rock chips and 16 metres grading 5.83 g/t Au and 7.20 g/t Ag from channel sampling. These results are historical in nature and have not been verified by a qualified person under National Instrument 43-101; they are considered relevant for exploration purposes but are not necessarily indicative of mineralization on the property. Lancaster's initial field program includes geological mapping, rock chip sampling, soil geochemistry and updated geophysics. This work is designed to refine geological models, define high-priority drill targets and support a systematic exploration strategy across the project area. Lancaster is committed to maintaining high standards of technical reporting and responsible exploration as it advances its portfolio of gold and critical mineral assets in Australia. The company also announces that Daniel Kang has resigned from the board of directors, effective as of the date of this release. The board thanks Mr. Kang for his long-standing contributions and dedication to Lancaster and wishes him continued success in his future endeavours. The company has initiated a process to identify and appoint a new director and will provide updates as appropriate. We seek Safe Harbor.
