Lode Resources Uncovers High-Grade Tin at Silver Hills Project

Lode Resources Strikes High-Grade Tin at Silver Hills Project

Lode Resources (ASX: LDR) has delivered impressive results from its newly acquired Silver Hills Project in Tasmania, with grab samples from historical waste dumps returning tin grades of up to 3.64% at the North Valley Lodes prospect. This discovery of high-grade tin at Lode Resources Ltd Silver Hills project significantly strengthens the company's critical minerals portfolio in Tasmania's premier West Coast mining district.

Major Tin Discovery Expands Critical Minerals Portfolio

The North Valley Lodes prospect has emerged as a standout discovery within Lode's recently acquired Silver Hills Project (EL6/2025), located near Waratah in Tasmania's highly prospective West Coast mining district. According to the announcement, initial reconnaissance sampling from historical waste dumps has returned exceptional tin assay results that highlight the potential for a significant high-grade mineralised system.

Furthermore, the results demonstrate the effectiveness of Lode's exploration targeting in this historically productive region. The discovery represents a significant milestone for the company's critical minerals strategy, positioning it advantageously in Tasmania's established mining corridor.

Key Assay Results from North Valley Lodes

The report states that the top seven samples averaged 1.43% tin, demonstrating consistent high-grade mineralisation across the prospect area. While grab sampling is selective in nature, these results provide strong qualitative evidence of significant tin mineralisation potential.

Moreover, the presence of elevated silver values in several samples adds additional value to the discovery. The combination of high-grade tin and silver mineralisation suggests a complex, well-developed hydrothermal system with multiple commodity potential.

"The identification of high-grade tin mineralisation at the recently acquired Silver Hills Project highlights the effectiveness of Lode's exploration targeting and reinforces the significant, yet underexplored, prospectivity of Tasmania's West Coast" – Keith Mayes, Managing Director

Strategic Location Advantages

The exploration licence completely surrounds the historic Mt Bischoff Tin Mine, providing exceptional geological context for the discovery. In addition, the positioning within a proven high-grade mineralised system offers significant exploration upside potential.

Historical workings extend over 500 metres of strike, indicating the scale and continuity of the mineralised system. Multiple historical adits and waste dumps provide evidence of extensive past mining activity and confirm the economic viability of the mineralisation style.

Understanding Tin Mineralisation: Why This Matters

What is cassiterite-bearing tin mineralisation?

The announcement describes tin mineralisation at North Valley Lodes as high-grade mesothermal mineralisation, with the primary tin mineral being cassiterite (SnO₂). This type of mineralisation typically forms in high-temperature hydrothermal systems and is often associated with granite intrusions, which is exactly what's observed in this region.

The presence of multiple accessory minerals including jamesonite, galena, tetrahedrite, and chalcopyrite suggests a complex, well-developed mineral system. These associations are typical of mesothermal tin deposits and often indicate the potential for additional valuable by-products.

Why it's significant for investors

Mesothermal tin deposits often contain high-grade zones suitable for selective mining operations. The grade ranges discovered at high-grade tin at Lode Resources Ltd Silver Hills project fall well above typical commercial tin mining grades globally.

Historical mining activity confirms the economic viability of this mineralisation style in the region. Furthermore, the proximity to established infrastructure and processing facilities enhances the development potential of any future discovery.

Industry Context

Tin is classified as a critical mineral globally, with increasing demand from renewable energy technologies, electronics manufacturing, and strategic defence applications. Tasmania has a strong tin mining heritage, with the nearby Mt Bischoff mine being one of Australia's most significant historical tin producers.

Current global tin supply constraints have driven prices to attractive levels for new project development. However, the strategic importance of domestic tin production has increased significantly due to supply chain security concerns.

Comprehensive Exploration Pipeline Delivers Multiple Catalysts

According to the report, Lode's exploration activities extend well beyond the Silver Hills discovery, with multiple projects advancing simultaneously across Tasmania and New South Wales. This diversified exploration approach reduces risk while maximising the potential for discovery success.

Active Drilling Operations

Montezuma Silver & Antimony Project (Tasmania) – The deepest hole completed to date reaches 617m downhole, with core processing and assays pending. This project represents one of Tasmania's most advanced silver-antimony developments.

Urulla Gold Project (NSW) – Follow-up drilling programme completed in the New England Fold Belt, with assays pending. The project targets intrusion-related gold systems similar to those found in major Australian gold districts.

Rock Abbey Antimony Prospect (NSW) – Initial 18-hole drill programme currently underway in the New England Fold Belt. Antimony's critical mineral status makes this prospect particularly strategic for the company's portfolio.

Planned Activities – Q2 2026

Granville East Tin Project Development

Surveying of the existing open pit has been completed to facilitate drilling design optimisation. Drilling is planned beneath the pit within mining lease 2M/2018, targeting extensions of known mineralisation at depth.

Extension drilling is planned south of the pit on exploration licence EL9/2019, aiming to expand the known resource base. A Sub-Audio Magnetic (SAM) drone survey is scheduled for early May to better define structural controls on mineralisation.

Metallurgical testwork is commencing at ALS Metallurgical laboratory in Burnie, which will provide crucial data for future processing optimisation. This work builds on the existing processing infrastructure at Granville, offering potential cost advantages for development.
