Altitude Minerals Advances Firenze Silver-Gold Project Towards Drilling

Altitude Minerals (ASX: ATT) has confirmed its drill-ready status at the 100% owned Firenze silver-gold project by Altitude Minerals Ltd in Nevada, USA, following months of detailed preparation. The company has completed extensive target validation studies and secured all necessary permits, positioning itself to test what could be a significant undrilled epithermal system in one of the world's premier mining jurisdictions.

The announcement marks a critical milestone for Altitude, with comprehensive geophysical surveys, structural mapping, and permitting now complete. Access work will commence in early May, followed by a planned 2,600-metre reverse circulation drilling program designed to test multiple high-priority targets from surface to 250-metre depth.

High-Grade Surface Results Point to Depth Potential

The Firenze silver-gold project by Altitude Minerals Ltd has delivered exceptional surface geochemistry results that provide strong evidence of a coherent mineralised system at depth. Historical surface rock chip sampling has returned outstanding grades including:

• 1,825 g/t silver and 22.5 g/t gold
• 534 g/t silver and 43.9 g/t gold
• 1,250 g/t silver and 9.3 g/t gold

These results are particularly significant given the project's geological setting as a low-sulphidation epithermal system. Furthermore, the consistently high silver-to-gold ratios and low base-metal concentrations suggest the current erosional level sits above the primary gold-silver deposition zone – exactly the scenario that drilling is designed to test.

"Firenze is a compelling, undrilled epithermal silver & gold system in Nevada, where multiple independent datasets point to a coherent mineralised system. With strong surface results, well-defined structural targets and permitting secured, we are looking forward to testing the system at depth."

– Duncan Chessell, Managing Director

World-Class Jurisdiction with Proven Track Record

The Firenze silver-gold project by Altitude Minerals Ltd benefits from its location in Nevada's Churchill County, positioned among some of the region's most successful mining operations. Nevada ranks #1 globally for mining investment attractiveness according to the Fraser Institute, reflecting established infrastructure, regulatory certainty, and a proven history of major discoveries.

The project sits within a highly prospective district containing several notable operations:

This regional context demonstrates the area's proven mineral endowment and successful track record of epithermal system development. Consequently, this provides strong validation for Altitude's exploration approach.

Understanding Epithermal Systems: Why Depth Matters

Epithermal mineral systems represent some of the world's highest-grade gold and silver deposits, formed when metal-rich hydrothermal fluids ascend from depth and encounter pressure changes that trigger mineral precipitation.

The key to these systems lies in understanding vertical metal zonation. As hydrothermal fluids rise through the crust, different metals precipitate at different levels based on temperature, pressure, and chemical conditions:

• Near Surface: Pathfinder elements (arsenic, antimony, mercury) dominate
• Intermediate Zone: Silver concentrates in cooler, more dilute conditions
• Boiling Zone: Gold concentrates where pressure drops trigger phase separation
• Deeper Levels: Base metals (copper, lead, zinc) may appear

At the Firenze silver-gold project by Altitude Minerals Ltd, surface sampling shows strong silver values with pathfinder elements, suggesting the boiling zone – where bonanza-grade gold mineralisation typically occurs – may be preserved at depth. This is precisely what the planned drilling program is designed to test.

Advanced Geophysics Defines Drill Targets

Altitude's systematic approach to target generation has integrated multiple independent datasets to build confidence in drill target selection. The program was led by Principal Geologist Gabe Graf, who previously worked with the Newmont exploration team that discovered additional mineralised vein systems at Nevada's Midas Mine using similar geophysical techniques.

CSAMT Geophysical Survey Results

The Controlled Source Audio-Frequency Magnetotellurics (CSAMT) survey has identified a major northwest-southeast trending structural corridor extending approximately 1.2 kilometres. Key findings include:

• Resistivity boundaries defining fault architecture
• Low resistivity zones interpreted as hanging wall fracture alteration networks
• Strong correlation with surface geochemistry results
• Multiple high-priority drill targets along main structure and associated splays

Drone Magnetic Survey

Complementing the CSAMT results, drone magnetic data highlights a clear boundary between magnetic and demagnetised zones, interpreted as hydrothermal alteration along fault structures. This independent dataset reinforces the structural interpretation and target confidence.

Strategic Drilling Program Design

The planned 2,600-metre RC drilling program has been carefully designed to test the highest-priority targets identified through the comprehensive geophysical and geological studies:
