Viridis Mining Colossus Project Drilling Results Exceed Expectations

Viridis Mining and Minerals Limited (ASX: VMM) has delivered exceptional drilling results from its flagship rare earth mining projects in Brazil, with infill drilling consistently exceeding modelled grades while exploration work expands the high-grade magnetic rare earth oxide (MREO) footprint across multiple prospects. The Viridis Mining Colossus Project drilling results represent a significant milestone in advancing one of the world's most promising ionic adsorption clay developments.

The latest reverse circulation (RC) and auger drilling campaign, which recommenced in October 2025, is advancing two critical workstreams: strengthening resource confidence ahead of Final Investment Decision targeted for Q3 2026, while simultaneously unlocking additional growth potential across the broader tenement package.

Outstanding High-Grade Results Exceed Expectations

The RC infill drilling program at the Northern Concessions continues to deliver exceptional grade results that consistently outperform the existing block model, particularly for high-value dysprosium and terbium mineralisation. Furthermore, these results demonstrate the robust nature of the underlying resource base.

Standout RC Drilling Results:

These results are particularly significant as they target pit feed areas used in the Pre-Feasibility Study, with grades consistently exceeding those previously modelled in the block model. Consequently, this outperformance supports expectations of a significant feed-grade uplift in the upcoming Resource update.

Exploration Success Expands High-Grade Corridor

Initial exploration auger results from the Northern Concessions eastern extension confirm a continuous, high-grade MREO corridor extending west to east, reinforcing the scale and resource growth potential beyond the current 493 Mt @ 2,508 ppm TREO resource footprint. Moreover, the exploration activities continue to validate the mineral exploration strategies employed across the project area.

Eastern Extension Highlights:

• FZ-AG-0260: 6m @ 4,395 ppm TREO and 1,337 ppm MREO – Ending in Mineralisation
• FZ-AG-0251: 6m @ 4,120 ppm TREO and 1,160 ppm MREO – Ending in Mineralisation

Greenfield Discovery Success Across Multiple Prospects

Exploration auger drilling at the Southern Complex and Campo do Coqueirinho has delivered strong thicknesses and high-grade results, highlighting the scale and growth potential across the broader tenement package. In addition, these discoveries demonstrate the effectiveness of geological surveying techniques employed throughout the exploration programme.

Regional Exploration Results:

All holes terminated in mineralisation, confirming the system remains open at depth and potentially along strike, highlighting significant expansion upside.

Understanding Ionic Adsorption Clay Deposits: A Game-Changing Advantage

Ionic Adsorption Clay (IAC) deposits represent a revolutionary approach to rare earth mining, offering significant advantages over traditional hard-rock rare earth operations. Unlike conventional deposits where rare earths are locked within complex mineral structures requiring energy-intensive processing, IAC deposits contain rare earths loosely bound to clay particles.

Furthermore, the understanding of mining geology fundamentals becomes crucial when evaluating these deposit types and their processing advantages.

Why IAC Deposits Matter to Investors

The strategic advantages of ionic adsorption clay deposits extend well beyond simple processing benefits:

• Simple Processing: Rare earths can be extracted using dilute salt solutions at ambient temperature
• Environmental Advantage: Minimal processing chemicals and lower environmental impact
• Lower Capital Requirements: Reduced infrastructure and processing complexity
• Higher Recovery Rates: Direct leaching achieves excellent metallurgical recoveries

The Colossus Project benefits from this advantageous geology, with previous metallurgical testing demonstrating over 60% MREO recovery using simple ammonium sulphate leaching at ambient temperature. However, the full potential of these deposits requires comprehensive understanding of resource estimation methods.

Advancing Toward Production: Clear Development Timeline

The Viridis Mining Colossus Project drilling results provide a solid foundation for advancing toward commercial production. However, several critical milestones must be achieved to realise this objective.

Managing Director Commentary

"The high-grade RC infill results from the Northern Concessions continue to confirm strong continuity, supporting conversion to Measured classification ahead of Final Investment Decision (FID) targeted for Q3 2026. This upgrade will underpin an updated Reserve and further strengthen project bankability as we complete the DFS and financing process in the coming months."

Rafael Moreno, Managing Director
