Lode Resources Ltd ('Lode' or 'Company') (ASX: LDR) is pleased to announce that initial reconnaissance sampling at the North Valley prospect, located within the newly acquired Silver Hills Project in Tasmania, has returned high tin grades of up to 3.64%. The North Valley Lodes has the potential to augment Lode's Granville Tin Project and significantly expands the Company's growing portfolio of critical minerals assets in the State's highly prospective West Coast mining district.

High-Grade Tin Identified at North Valley Lodes Prospect¹⁻³

Initial reconnaissance sampling from historical waste dumps at the North Valley Lodes workings, the second prospect to be investigated within the recently acquired Silver Hills Project (EL6/2025), have returned high-grade tin assays (see Table 1 and Figure 2). These results highlight the strong potential for a high-grade mineralised tin system within the project area and further demonstrate the prospectivity of Lode's newly expanded Tasmanian landholding.

The top seven samples average 1.43% tin with the highest value being 3.64% tin. Grab sampling is selective in nature with resultant assay grades considered to be indicative only, providing qualitative evidence of mineralisation, rather than representative grades of which may be lower or higher.

The North Valley Lodes prospect is located within the recently acquired Silver Hills Project (EL6/2025) located near the township of Waratah, part of Tasmania's premier West Coast mining district. The Exploration License surrounds the historic Mt Bischoff tin mine held by Bluestone Metals on Mine Lease 12M/2006, highlighting the strong mineral endowment of the area and placing the project within an established and well-endowed mining province

The North Valley Lodes workings extend over more than 500 metres of strike and comprise a series of historical adits and waste dumps, indicating the presence of a potentially significant mineralised system. Systematic sampling and mapping of this extensive tin occurrence is continuing. The North Valley Lodes has the potential to augment Lode's Granville Tin Project.

The prospect represents a strengthening of the Company's growing portfolio of critical mineral assets in Tasmania. Mineralisation at the north value lodes is characterised as high-grade mesothermal mineralisation. Minerals present include cassiterite, jamesonite, galena, tetrahedrite, and chalcopyrite.

Granville East Tin Planned Exploration

Surveying of the existing Granville East Open Pit Mine outline has been undertaken during March to help facilitate design of a drilling program to test beneath the pit within Lode's existing mining lease 2M/2018. Drilling is also planned south of the Granville East pit on the surrounding exploration license EL9/2019 to test for extensions to the tin mineralisation. Subject to approvals, drilling is planned to commence during the June quarter.

A Sub-Audio Magnetic (SAM) drone survey has been designed to evaluate the conductive and magnetic units associated with magnetite-tin skarn mineralisation at Granville East mine and along the controlling structure to the north and south of this deposit. This survey is anticipated to commence early May.

Metallurgical testwork on material previously mined at the Granville East pit and stockpiled for processing at Lode's Granville processing facility will soon be underway at the ALS Metallurgical laboratory in Burnie.

About Lode Resources

Lode Resources Ltd (LDR) is an ASX-listed explorer focused on the highly prospective but under-explored New England Fold Belt in north-eastern NSW and the Montezuma Silver & Antimony Project located in Tasmanian's premier West Coast Mining Province. The Company has assembled a portfolio of brownfield precious and base metal assets characterised by:

• 100% ownership;
• Significant historical geochemistry and/or geophysics;
• Under-drilled and/or open-ended mineralisation; and
• Demonstrated high-grade mineralisation and/or potential for large mineral occurrences.

This has resulted in a portfolio of assets with diverse mineralisation styles consisting of four core projects of current focus

1. Montezuma Silver & Antimony Project – Located on the west coast of Tasmania, a region well known for mining activity, the Project consists of a high-grade antimony-silver-lead deposit with initial development, advanced metallurgical test work and significant beneficiation infrastructure.
2. Uralla Gold – Located 8km west of the Uralla township, this goldfield was one of the earlier goldfields discovered in NSW and a significant gold producer in the 1850's. Despite this long history the mineralisation style has only recently been recognised as being an Intrusive Related Gold System (IRGS) and this has strong implications for this project's discovery potential. Lode's holdings cover over 300 square kilometres.
3. New England Antimony Project – Located in one of Australia's most prolific antimony producing provinces, 19 antimony prospects have already been identified within the Exploration Licences (EL) EL9662 and EL9319, both controlled 100% by Lode. The project is anchored by the Magwood Mine, discovered in the 1880s and mainly worked between 1941 and 1970, and was Australia's primary producer of antimony.
4. Granville Tin Project – Located approximately 5 km west of Zeehan in Tasmania, this project is known for its high-grade tin skarn mineralisation. Infrastructure includes connection to grid power, ball mill, gravity tables, spirals, tankage, raw water and a recently constructed tailings dam.
5. Silver Hills Silver & Antimony Project – Located on the West Coast of Tasmania this Project completely surrounds the historic Mt Bischoff Mine and is high prospective for high-grade silver-antimony mineralisation such as that identified at the Silver Cliffs prospect.
