Lancaster Resources LiDAR Results and Field Trip Data from Lake Cargelligo Gold Project

VANCOUVER, British Columbia, Oct. 30, 2025 (GLOBE NEWSWIRE) -- Lancaster Resources Inc. (CSE:LCR) (OTC Pink:LANRF) (FRA:6UF) (“Lancaster” or the “Company”) reports new LiDAR and field data analysis revealing multiple gold-bearing targets and previously unmapped vein systems at its 100% owned Lake Cargelligo Gold Project in New South Wales, Australia. The new data sets were acquired during an on-site field visit and through data acquisition as part of the Company’s ongoing Phase 1 exploration program.

LiDAR and Field Trip Highlights

Extensive Strike Length: 75km of prospective granite-sedimentary contact strike length now secured by Lancaster’s tenure, which is largely unexplored;
Multiple Vein Systems: Newly mapped veins and historical workings at the Greater Avoca prospect, where historical rock-chip sampling returned up to 3.66 g/t Au.¹
Josephine Moulder Trend: The system remains open northward, supported by widespread Au-Ag-Te-Bi-As-Mo-Sb anomalies in historical auger drilling at Josephine Moulder North ².
Newly Defined Targets: LiDAR interpretation revealed unrecorded clusters of potential old workings and vein swarms between Josephine Moulder and Avoca, including three large-scale zones along the Central Contact that have seen no previous exploration.
Soil and Geochemical Anomalies: Historical data indicates Au-As-Cu-Zn anomalies along the Central Contact strike from LiDAR-interpreted veins, reinforcing the district-scale mineralization model.
Eastern Contact Opportunity: Widespread untested features—including possible workings and quartz veins—extend over > 5 km along the Eastern Contact, an area with no recorded exploration.
Additional Upside: Early evidence of tin (Sn) enrichment highlights potential for additional mineralization in parallel with gold-silver exploration.

Target Prospects

Previous exploration at the project focused on the Josephine Moulder - Mount Wilga prospects, where auriferous veins-breccias outcrop over hundreds of meters, with significant historical workings, within sedimentary rocks proximal to the Ungarie Granite contact. Minimal historical exploration has occurred beyond these prospects despite a large strike length of the prospective granite-sedimentary contact outcropping or lying under shallow cover.

Lancaster’s endeavours at the Lake Cargelligo Project are gaining momentum with the Company’s initial site visit to confirm historical exploration reports, publication of its NI 43-101 Technical Report, and interpretation of LiDAR data now complete. Additionally, an in-depth review of existing geophysical data and targeting study by an expert, independent consultancy is nearing completion.

Through the use of systematic, results-based exploration programs, the Company aims to assess the Lake Cargellico Project in a holistic manner, principally for large-scale Au-Ag mineralization as well as for Sn-W enrichment.

Josephine Moulder / Mt. Wilga Prospect:

Four rock samples were taken as previously announced;
Several rock chips with visible gold were not sampled to ensure representative sampling of the exposed mineralization system:
- Returned up to 31.5g/T-Au and 114g/T-Ag³, along with highly anomalous pathfinder geochemistry⁴.
The Josephine Moulder system likely remains open northward with widespread Au-Ag-Te-Bi-As-Mo-Sb anomalism in historical auger drilling at Josephine Moulder North.

Avoca and North Quarry:

Large gravel pit lying north of the historical Avoca mine shaft and its associated line of old pits:
- Avoca shaft had a peak historical rock chip of 3.66g/T-Au, ~13m deep along >300m trend⁵.
6 rock chips sampled as per previously announced;
Highly anomalous pathfinder geochemistry (Au-Ag-As-Bi-Sb) supports significant further exploration;
Lancaster reconnaissance identified a large, new veining zone north of Avoca, which was previously unsampled, that returned strongly anomalous Au-Bi-Te and lies subparallel to the Avoca line of workings, along with numerous other potential veins and workings interpreted in LiDAR data over the Greater Avoca prospect; and,
Supported additional land acquisition as previously announced along granite-sedimentary contact.

New Target Areas:

Interpretation of existing LiDAR data and legacy soil sampling geochemistry has identified a number of new target areas at the project that fall along the Central and Eastern Contacts - being the prospective contact of Ungarie Granite and hosting sedimentary lithologies - while the Western Contact falls under shallow cover. Combined, Lancaster’s tenure now hosts ~75km of prospective granite-sedimentary contact, much of it completely unexplored. New target areas include:

A potential northwest-southeast trending vein swarm along the Central Contact ~3km south of Avoca within EL 9775 and possibly extending undercover into ELA 6970;
Potential additional workings in the greater Avoca-North Quarry area;
Potential cluster of unrecorded historical pits and trenches identified along the Central Contact ~6km north of Avoca within EL 9775;
Potential ~4km long, open-ended anomalous Au-As-Cu-Zn-(Pb) soil trend along the Central Contact, with a potential northwest-southeast vein swarm occurring immediately to the south; and,
Potential ~5km strike of historical workings occurring extensively along the Eastern Contact.

In addition to a Au-Ag focus, the Company also considers Lake Cargelligo prospective for Sn-W mineralization and will look at advancing exploration for both commodity target suites in parallel.

“Our team is extremely encouraged by these LiDAR results, which support the presence of high-grade gold and silver mineralization at Lake Cargelligo. They add validity to our exploration model and path forward as we unlock district-scale gold and precious metal projects. We remain focused on building the value of this highly prospective property,” said Andrew Watson, President and CEO of Lancaster Resources.

The samples were taken by the Lancaster Australia team with the aim of confirming historically reported rock chip grades as previously announced. Further field exploration is required to continue the validation of LiDAR-identified features and upside. LiDAR is typically used to identify areas of interest, veins, historical workings, outcropping, etc.
