West Coast Silver Drilling Program Unlocks Elizabeth Hill Expansion

West Coast Silver Launches Major Drilling Program to Unlock High-Grade Elizabeth Hill System

West Coast Silver Limited (ASX: WCE) has announced a significant 4,000-metre Reverse Circulation (RC) drilling program at its flagship Elizabeth Hill Silver Project in Western Australia's Pilbara region. The March 2026 campaign is designed to expand the footprint of high-grade silver mineralisation and support the company's inaugural Mineral Resource Estimate targeted for Q3/Q4 2026.

The west coast silver drilling program specifically targets Elizabeth Hill North and South along the Munni Munni Fault (MMF), building on the success of 2025 diamond drilling that identified bonanza-grade silver intersections. All targets are located within approximately 150 metres of surface, highlighting exceptional potential for rapid and cost-effective resource growth.

Key Program Highlights:

• 4,000m RC drilling program commencing March 2026
• Targets extensions of high-grade mineralisation from 2025 drilling results
• All drilling within ~150m of surface for low-cost resource development
• Results expected progressively during Q2 2026
• Program designed to support inaugural Mineral Resource Estimate in Q3/Q4 2026

The RC drilling contract has been awarded to NexGen Drilling Pty Ltd, with the program expected to take approximately four to six weeks to complete, subject to weather and operational conditions.

Executive Leadership Sees Major System Potential

Executive Chairman Bruce Garlick emphasised the strategic importance of the west coast silver drilling program, stating that the company's diamond and aircore drilling programs have confirmed the structural system hosting silver mineralisation extends significantly beyond the boundaries of the historic mine.

"The identification of multiple near-mine targets supports our view that Elizabeth Hill represents part of a larger silver mineralised system along the Munni Munni Fault. With all targets shallow and proximal to existing infrastructure, success would position the Company strongly for rapid resource growth and a clear pathway to development."

— Bruce Garlick, Executive Chairman

The program is specifically designed to:

• Expand known strike and depth extents of the deposit
• Test new targets at Elizabeth Hill North and South
• Deliver systematic drilling required for the first Mineral Resource Estimate
• Support rapid resource growth with a clear development pathway

Understanding Reverse Circulation Drilling

Reverse Circulation (RC) drilling is a cost-effective exploration method that uses compressed air to lift rock chips to the surface through dual-wall steel pipes. This technique is particularly valuable for resource definition because it provides:

• Continuous rock chip samples from surface to target depth
• Faster drilling rates compared to diamond drilling
• Lower cost per metre whilst maintaining sample quality
• Immediate visual assessment of mineralisation

For investors, RC drilling represents an efficient way to test multiple targets and expand resource boundaries without the higher costs associated with diamond drilling. The technique is ideal for West Coast Silver's shallow targets, enabling rapid resource growth at minimal expense.

Industry Context: RC drilling is the backbone of resource definition in Western Australian mining, with successful programs often leading to significant resource upgrades and enhanced project economics.

Elizabeth Hill's Exceptional Production Pedigree

West Coast Silver's flagship project boasts one of Australia's most impressive historical silver production records, with characteristics that set it apart from typical silver developments:

The project's world-leading silver grades enabled production of substantial silver volumes from minimal ore tonnage, demonstrating the extraordinary quality of the mineralisation system. Historic operations used simplistic processing techniques focused only on native silver extraction, suggesting significant potential for enhanced recovery using modern processing methods.

Key Investment Advantages:

• Proven production history with exceptional grades
• Untapped expansion potential – deposit remains open at depth and along strike
• Strategic land consolidation – 180km² contiguous package covering significant portions of the Munni Munni fault system
• Existing mining lease with potential processing options at nearby Radio Hill site

What Makes This West Coast Silver Drilling Program Different?

The upcoming west coast silver drilling program represents more than typical exploration activities. Furthermore, it builds systematically on previous successes whilst targeting immediate resource growth opportunities within proven geological frameworks.

The program's strategic focus on Elizabeth Hill North and South leverages existing geological understanding to maximise success probability. Moreover, all targets remain within economic drilling depths, ensuring cost-effective resource development pathways.

In addition to expanding known mineralisation boundaries, the drilling will test new geological interpretations that could unlock additional high-grade zones. However, the program maintains focus on areas with established infrastructure access and processing potential.

Strategic Expansion Timeline and Catalysts

West Coast Silver has established a clear pathway for systematic resource development, with multiple near-term catalysts positioned to drive value creation:

Immediate Catalysts (Q1-Q2 2026):

• March 2026: west coast silver drilling program commencement
• Q2 2026: Progressive assay results release
• 4-6 weeks: Expected drilling completion timeline

Medium-Term Milestones (Q3-Q4 2026):

• Q3/Q4 2026: Inaugural Mineral Resource Estimate delivery
• Ongoing: Geological model updates incorporating new drilling data
• Strategic: Resource expansion along Munni Munni Fault system

The systematic approach positions West Coast Silver to rapidly advance from exploration success to resource definition. The shallow nature of all targets and proximity to existing infrastructure enables accelerated development timelines compared to typical greenfield projects.

Investment Thesis: High-Grade Silver in a Strategic Location

West Coast Silver presents a compelling investment opportunity centred on exceptional silver grades, proven production history, and significant expansion potential within a consolidated land package. The combination of historical production excellence and modern exploration techniques creates multiple value drivers.

Competitive Advantages:

1. World-class historical grades averaging 2,194 g/t silver
2. Shallow mineralisation within 150m of surface enabling low-cost development
3. Extensive land consolidation covering 180km² of prospective fault systems
4. Proven geological system with multiple exploration targets identified
5. Strategic location with potential processing options and existing infrastructure

Growth Catalysts:

• Immediate resource expansion through systematic RC drilling
• Multiple target areas along the Munni Munni Fault system
• Modern processing potential to enhance recovery beyond historical methods
• Clear development pathway supported by existing mining lease and infrastructure access

The upcoming west coast silver drilling program represents a critical inflection point. Success could potentially validate the broader Elizabeth Hill silver system and support rapid resource growth through cost-effective near-surface expansion.

Why Should Investors Monitor West Coast Silver Now?
