Lithium Energy Copper Discovery Reveals Major Porphyry System at Bajool

Lithium Energy Uncovers Major Porphyry Copper System at Bajool Prospect

Lithium Energy Limited (ASX:LEL) has delivered a significant breakthrough at its Capricorn Gold-Copper Belt Project, with advanced geophysical surveys revealing a potential large-scale porphyry copper-molybdenum system at the Bajool Prospect in central Queensland. This Lithium Energy copper discovery represents a major milestone for the company, with 3D electrical geophysical surveys—co-funded by a $250,000 Queensland Government grant—detecting multiple coincident anomalies extending to significant depths.

The discovery reveals what appears to be a well-preserved and largely untested mineralised system. Furthermore, this breakthrough positions Lithium Energy strategically within one of Australia's most significant historic mining districts, offering investors exposure to a rare discovery opportunity with substantial scale potential.

Advanced Geophysical Surveys Reveal Extensive Mineralisation

The comprehensive geophysical investigation comprised two cutting-edge survey techniques that have transformed understanding of the subsurface geology. The strategic approach allowed for precise targeting of potential porphyry systems ahead of the planned drilling campaign.

3D Direct Current Induced Polarisation (3DIP) Survey:

• 84 transmitter injections across 15 survey lines
• 189 receiver stations with optimal 100m spacing over priority areas
• Enhanced resolution targeting at the historic Limonite Hill mineral occurrence

Magnetotelluric (MT) Survey:

• 178 stations positioned on a systematic 200m x 200m grid
• Deep penetration capabilities extending well beyond previous exploration depths
• Advanced 3D modelling to accurately define mineralised zones

The surveys were strategically designed to investigate deeper than previous exploration efforts. In addition, the enhanced resolution provides unprecedented subsurface detail, significantly improving drilling success probability compared to previous exploration campaigns.

Significant Geophysical Anomalies Detected

The survey results have identified multiple high-priority targets that strongly suggest a substantial porphyry copper-molybdenum system. These findings validate the Lithium Energy copper discovery and provide clear drill targets for the upcoming campaign.

Primary Anomaly at Limonite Hill

The most compelling target exhibits characteristics typical of major porphyry systems worldwide. However, what makes this discovery particularly exciting is its size and depth potential.

• Large, strong chargeable zone measuring 20 mV/V
• 700m strike length with 200m width extending beyond 500m depth
• Strengthening with depth toward the south-east, indicating potential for expanded mineralisation
• Deep, semi-linear resistivity response suggesting the structural core of a porphyry copper deposit

Secondary Targets

Moreover, several additional targets have been identified across the broader survey area. These secondary zones provide multiple opportunities for discovery and suggest a district-scale mineralised system.

• Ultimo prospect showing shallow chargeable zones east of Limonite Hill
• High resistivity zones (over 5000 ohm/m) indicating widespread silicification from high-temperature intrusives
• Potentially deeper system at Ultimo with upper silicified portions near surface

Strong Foundation from Historic Results

The geophysical targets build upon encouraging historic drilling results, providing strong validation for the newly identified anomalies. For instance, the significant intercept from diamond drill hole D28-DDH4 at Limonite Hill demonstrates the quality of mineralisation present.

The historic results include 16m at 0.57% copper and 441 ppm molybdenum from 156m depth. Furthermore, a higher-grade zone returned 2m at 3.22% copper, 252ppm molybdenum, and 17.7ppm silver from 160m depth.

These results provide strong validation for the Lithium Energy copper discovery and support the interpretation of a substantial porphyry system. Additionally, they demonstrate that mineralisation extends well beyond surface expressions.

Understanding Porphyry Copper Deposits

What are Porphyry Copper Deposits?

Porphyry copper deposits represent some of the world's largest and most economically significant copper resources. These deposits form when copper-rich magma intrudes into the Earth's crust, creating large, low-to-moderate grade ore bodies that can contain millions of tonnes of copper.

Key characteristics include:

• Large tonnages with consistent grades across extensive areas
• Associated metals including molybdenum, gold, and silver
• Alteration halos extending well beyond the core mineralised zone
• Long mine lives due to substantial resource bases

Why this matters to investors

Porphyry copper deposits offer the potential for large-scale, long-life mining operations with predictable production profiles. However, they require significant capital investment but provide substantial economic returns when successfully developed.

Comprehensive Drilling Programme Set to Begin

Lithium Energy has designed a strategic two-phase drilling programme to systematically test the identified targets. The programme will provide comprehensive coverage whilst prioritising the highest-potential targets for immediate follow-up.

Phase 1: Deep Diamond Drilling at Limonite Hill

The initial phase focuses on establishing the depth extent and quality of mineralisation at the primary target. Furthermore, this phase aims to validate the geophysical interpretation and guide subsequent exploration.

Objectives:

• Establish depth extent of potential porphyry copper-molybdenum mineralisation
• Determine style, distribution, and grade of copper, molybdenum, gold, and silver
• Test strike extent of historic mineralisation identified in previous drilling

Phase 2: Extensive Air-Core Drilling Programme

The second phase expands testing across the broader geophysical survey area. Additionally, this programme will provide critical data for future resource definition work.

• Up to 89 shallow air-core holes across the geophysical survey area
• Bedrock lithology mapping beneath transported cover
• Geochemical fertility assessment for porphyry copper deposits
• Validation of geophysical interpretations across the broader target area
