Terrain Minerals Expands Gold Drilling at Lightning & Monza Prospects

Terrain Minerals Expands Gold Drilling Program at Lightning & Monza as US Marketing Efforts Gain Traction

Terrain Minerals (ASX: TMX) has announced a significant expansion of its gold drilling program at the Lightning and Monza Prospects within its 100% owned Smokebush Project in Western Australia, while also reporting strong investor interest following recent US marketing activities.

Expanded Drilling Program Targets Multiple Gold Structures

Terrain has enhanced its reverse circulation (RC) drilling campaign at the Lightning and Monza Gold Prospects, increasing the program from 17 holes and 3,350 meters to 20 holes totaling 4,300 meters. The expansion comes after promising results from earlier drilling phases and ongoing refinement of the company's IP modeling.

The expanded program specifically targets:

• Multiple parallel structures identified through evolving IP modeling
• Extended and adjusted hole designs based on field observations
• Continuation of high-grade gold and silver targets following earlier success

"The expanded drilling program reflects our growing confidence in the Smokebush Project's potential to deliver significant gold and silver mineralisation," said Justin Virgin, Executive Director of Terrain Minerals. "Our systematic approach is building a compelling picture of the resource potential at Lightning and Monza."

Drilling is expected to be completed by June 30, 2025, with samples to be transported to Perth for analysis. The company anticipates providing results to the market in August 2025.

Strong Investor Response During US Marketing Campaign

The announcement also detailed the company's recent marketing activities in New York, where Executive Director Justin Virgin conducted a series of meetings with institutional investors, fund managers, and stockbrokers. The company reported particularly strong interest in its Larin's Lane Gallium/REE oxide project, alongside positive sentiment toward the ongoing gold and silver drilling at Smokebush.

Key marketing activities included:

• 21+ meetings at the 121 New York conference
• Presentations to Australian and American government officials
• Over 60 meetings with fund managers, brokers/analysts, and high-net-worth investors

The company noted significant investor interest in both its gold projects and its emerging Gallium/REE oxide project at Larin's Lane, which aligns with growing global demand for critical minerals.

Understanding IP Modeling: A Key Tool in Modern Gold Exploration

Induced Polarization (IP) surveys represent one of the most powerful geophysical methods used in modern mineral exploration, particularly for gold deposits. The technique measures the electrical chargeability of subsurface materials, helping identify zones with potential sulfide mineralization that often accompany gold deposits.

How IP Surveys Work in Gold Exploration

IP surveys work by sending electrical currents into the ground and measuring how rocks and minerals respond. Gold-bearing sulfides (like pyrite) store electrical charge differently than surrounding rock, creating distinctive "chargeability" signatures that can be mapped in 3D.

In Terrain's case, IP modeling has revealed a 600-meter-long chargeability anomaly parallel to the Monza Gold prospect, indicating potential for significant sulfide mineralization that may host gold. The company is using this data to refine its drilling targets, allowing for more precise hole placement and increased chances of intersecting mineralization.

Why this matters to investors: Companies using advanced IP modeling can target drilling more effectively, reducing costs and increasing discovery potential. For Terrain, the expanded drill program based on IP results demonstrates confidence in the underlying geological model and potential for resource expansion.

Project Portfolio and Strategic Direction

Terrain maintains a diverse project portfolio across Western Australia and Queensland, with a strategic focus on both precious metals and critical minerals. The company's key assets include:

Smokebush Project (100% owned)

• Located in the prospective Yalgoo Mineral Field of Western Australia
• Primary focus on Monza and Lightning gold prospects following recent high-grade drilling results
• Previous drilling at Lightning returned 11m @ 6.03 g/t gold and 43.5 g/t silver
• Strategically positioned near established mining operations including Golden Grove (29 Metals) and Mt Gibson (Capricorn Metals)

Larin's Lane Gallium & REE Prospect

• Maiden drilling in 2023 discovered broad zones of gallium mineralization across a 9km x 3km area
• Project benefits from year-round access and proximity to established infrastructure
• Metallurgical studies underway as part of the MIRWA REE study funded by industry and WA government

Additional Projects

• Biloela Copper & Gold Project (Queensland) – recently granted after two-year process
• Lort River Project – selective metallurgical testing underway
• Carlindie Lithium & Gold Project – strategically located between Wildcat Resources and Kali Metals in East Pilbara

Investment Thesis: Multiple Growth Catalysts in Gold and Critical Minerals

Terrain Minerals presents an interesting investment proposition with exposure to both traditional precious metals and emerging critical minerals sectors. The company's current market focus centers on three key areas:

1. Near-term gold exploration upside: The expanded drilling program at Lightning and Monza offers potential for resource definition following high-grade intercepts of 11m @ 6.03 g/t gold and 43.5 g/t silver.

2. Strategic critical minerals exposure: The Larin's Lane Gallium/REE oxide project provides exposure to critical minerals essential for technology applications, with gallium increasingly important in semiconductor manufacturing.

3. Project diversity and optionality: With multiple projects across different commodities and jurisdictions, Terrain offers investors commodity diversification while maintaining a primary focus on gold.

The company's projects benefit from proximity to established mining infrastructure in Western Australia, potentially reducing development costs should resources be defined. Additionally, management has maintained an openness to commercial discussions regarding potential asset divestment or joint venture arrangements, providing multiple pathways to value creation.

Why Investors Should Watch Terrain Minerals

Terrain Minerals represents an interesting exploration play with several compelling reasons for investors to monitor its progress:

1. Active drilling program with near-term results: With the expanded gold drilling at Lightning and Monza set to conclude by June 30, investors can expect results by August 2025, providing a clear catalyst.

2. Exposure to both precious metals and critical minerals: The company offers a balanced portfolio with both traditional gold assets and emerging critical minerals exposure through its gallium project.

3. Strategic location of key assets: The Smokebush Project sits within an established gold mining region with proximity to processing infrastructure, while the Larin's Lane project has year-round access.

4. Increasing international investor interest: The strong response during US marketing activities suggests growing awareness of the company's projects, particularly in the critical minerals space.

5. Clear development pathways: With defined next steps across its project portfolio and metallurgical studies underway, the company has established a structured approach to advancing its assets.

Key Takeaway:
Terrain Minerals has positioned itself with a dual focus on high-grade gold exploration and critical minerals development, providing investors exposure to both traditional precious metals and emerging technology metals. With active drilling programs and metallurgical studies underway, the company offers multiple near-term catalysts while maintaining a diversified project portfolio across Western Australia and Queensland.
