Enova Mining Ltd Launches Major Diamond Drilling Campaign

Enova Advances East Salinas REE Project with Diamond Drilling Campaign

Enova Mining Ltd (ASX: ENV) is preparing to launch its maiden diamond drilling campaign at the East Salinas Project in Brazil, targeting high-grade rare earth element (REE) mineralisation across three primary prospects within the Medina Granitic Complex.

Drilling Campaign Set to Validate Surface REE Anomalies

Enova Mining Ltd has awarded a drilling contract with mobilisation expected in late August to test the depth continuity of surface REE mineralisation that previously returned values up to 1.87% TREO (Total Rare Earth Oxide). The programme includes 10-15 diamond drill holes ranging from 50-100m depth for a total of approximately 1,000 metres along a 4km strike.

"Our exploration team is excited by the prospectivity of the newly discovered East Salinas project. We are pleased to secure funding allowing us to commence diamond drilling at Bald, Naked and Hairy Hills, and the saddles between. Our objective is to determine the extent and depth of mineralisation within these most prospective zones of the Medina Intrusive Complex," stated CEO Eric Vesel.

The Enova Mining Ltd diamond drilling campaign follows a systematic surface sampling programme encompassing 57 rock chip samples and three bulk samples across key target zones. These samples have been submitted to SGS Geosol Laboratory with results expected by the end of August, which will help refine the final drill targets.

Preliminary Metallurgical Testing Underway

In parallel with the exploration activities, Enova has initiated preliminary "sighter" metallurgical test work at CIT Senai Laboratory in Belo Horizonte. The company is utilising bulk granite rock chip samples (approximately 100kg from each of three locations) to evaluate:

• Grinding work index
• Mineral liberation analysis
• Heavy liquid separation
• Heavy mineral concentration studies

These tests aim to establish early-stage processing pathways and assess the amenability of the mineralisation to low-cost beneficiation and concentration techniques. Additionally, six samples have been submitted for leach testing to evaluate potential ionic adsorption clay-style rare earth mineralisation.

Emerging Geological Model Enhances Project Potential

A key development in Enova's understanding of the East Salinas Project is the emerging geological model suggesting that Naked Hill, Bald Hill, and Hairy Hill may form part of a single, much larger granitic body within the Medina Intrusive Complex. This significantly enhances the project's exploration potential, with the three outcropping bodies potentially representing surface expressions of a single, mineralised system at depth.

The East Salinas Project covers a substantial 22,706 hectares across 12 tenements in Minas Gerais, Brazil. Importantly, the outcrops are remotely located away from farming areas or communities, which bodes well for future permitting processes.

Understanding Rare Earth Elements and Their Importance

Rare earth elements comprise a group of 17 metals that, despite their name, are relatively abundant in the Earth's crust but rarely occur in concentrated, economically viable deposits. These elements are critical components in technologies that power the green energy transition, including electric vehicles, wind turbines, and electronics.

The East Salinas Project is particularly notable for its high magnetic rare earth content, with NdPr (neodymium + praseodymium) oxide ratio reaching up to 38.8%. NdPr is especially valuable as it's essential for producing permanent magnets used in electric vehicle motors and wind turbine generators. The project also shows an average Heavy Rare Earth Oxide (HREO) ratio around 9.95%, which includes elements like dysprosium and terbium that are crucial for enhancing the temperature resistance of magnets.

Brazil's Advantages as a Mining Jurisdiction

Brazil offers Enova several strategic advantages as an exploration and development location:

• Stable, low-risk environment for mining investment
• Well-established and globally competitive resources sector
• No government ownership mandates
• Minimal interference and a progressive regulatory framework
• Attractive cost structure and highly skilled workforce
• Advanced mining services sector and robust infrastructure
• Proximity to key cities

These factors position Brazil, and particularly the states of Minas Gerais and São Paulo, as prime destinations for resource investment, especially in critical metals needed for the energy transition.

Next Steps and Development Timeline

Enova's immediate next steps include:

1. Finalising drill collar locations for the maiden 10-15 hole diamond drilling programme
2. Analysing assay results from the recently submitted rock chip samples (expected by end of August)
3. Continuing metallurgical test work at CIT Senai
4. Refining target definition along the 4km strike

These activities are designed to validate a low-cost processing pathway and support a scalable development strategy across the broader Medina Granite Complex.

Why Investors Should Follow Enova Mining

Enova Mining represents a compelling opportunity in the critical minerals space, particularly for investors looking for exposure to rare earth riches. The company's strategic positioning includes:

1. Focus on Critical Minerals: Enova is targeting rare earth elements essential for clean energy technologies, positioning it within a high-growth sector with strong long-term demand fundamentals.

2. Promising Initial Results: Surface sampling showing up to 1.87% TREO with high NdPr content (up to 38.8%) indicates potential for an economically significant deposit.

3. Multiple Projects: Beyond East Salinas, Enova holds a diversified portfolio including the Coda Group (clay-hosted REE), Poços de Caldas (ionic adsorption clay REE), Charley Creek (alluvial rare earths), and Lithium Valley Projects.

4. Strong Jurisdiction: Operating in Brazil provides advantages in terms of established mining regulations, infrastructure, and skilled workforce.

5. Systematic Approach: The company is methodically advancing from surface sampling to the diamond drilling campaign, demonstrating a disciplined exploration strategy similar to other discoveries.

With the rare earth market projected to grow significantly due to increasing demand from renewable energy, electric vehicles, and defence technologies, Enova's focus on these critical minerals places it in a favourable position to capitalise on global trends toward decarbonisation and technological advancement.
