Terrain Minerals Uncovers High-Grade Gold Exploration Results at Smokebush

Terrain Minerals Unveils Strategic Growth Path with Gold, Gallium and Copper Portfolio

Terrain Minerals (ASX:TMX) is advancing a diverse portfolio of critical and precious metals projects in premier Australian mining jurisdictions, with promising developments across gold, gallium, and copper assets that position the company at the intersection of traditional mining and future-facing commodities.

Gold Exploration Breakthrough at Smokebush Shows Significant Potential

Terrain's Smokebush Project in Western Australia has delivered exceptionally promising drilling results at the Lightning and Monza gold targets, highlighting the project's significant potential. Recent RC drilling at Lightning revealed impressive intercepts including:

• 11 metres @ 6.03 g/t gold plus 43.5 g/t silver from 75 metres
• 3 metres @ 6.12 g/t gold from 26 metres
• 5 metres @ 3.77 g/t gold from 180 metres

The company has recently completed a 3,550-meter RC drilling program across 17 holes at the Lightning and Monza parallel structures, with results now pending. This program, which commenced on 20 May 2025, is utilising a new induced polarisation (IP) model that has been instrumental in revealing potential parallel structures and mineralisation extensions.

"Our new IP model is revolutionising our understanding of the Smokebush Project's geological structures, particularly at Lightning and Monza. The early drilling results demonstrate significant gold-silver mineralisation that warrants extensive follow-up." – Justin Virgin, Executive Director at Terrain Minerals

Strategic Gallium Resource Development

In a significant move into critical minerals, Terrain has established a JORC-compliant gallium exploration target at its Larin's Lane project within the Smokebush tenement package. What makes this development particularly noteworthy is:

• The exploration target covers only 5% of the 27km² target area (a 9km by 3km area that remains open)
• 70% of drill holes returned impressive gallium intersections up to 64 meters wide
• Multiple high-grade zones up to 53.74 g/t (ppm) Ga₂O₃

The strategic importance of this development cannot be overstated, as gallium is classified as a critical metal by major economies including the USA, UK, Japan, EU, and Australia. With 98% of global gallium supply currently from China, Terrain's Australian resource presents a compelling opportunity for supply diversification.

Metallurgical studies are currently underway through a partnership with the Minerals Research Institute of Western Australia (MRIWA), with results expected in late Q4 2025.

Copper-Gold Portfolio Expansion in Queensland

Complementing its Western Australian assets, Terrain has secured exploration permits totalling 2,462km² in the Biloela region of Queensland, approximately 400km northwest of Brisbane. This extensive copper-gold exploration package:

• Contains seven historic copper-gold mines and ten additional mineralisation occurrences
• Features geological settings confirmed to host VMS, porphyry copper-gold, and epithermal gold mineral systems
• Sits just 13km north of the productive Cracow Gold Mine

The company's geological team has identified seven priority copper and gold targets, with exploration activities now accelerating following the granting of permits after a two-year process.

What Makes Gallium a Compelling Investment Opportunity?

Gallium represents a fascinating investment proposition due to its critical applications in modern technology. This relatively obscure element is essential for:

• Semiconductors and computer chips
• Electronic circuitry and photovoltaic cells
• Defence applications
• NdFeB magnets and LED technology
• Next-generation quantum computing and AI systems

Gallium's unique properties allow for chips and electronic components that draw less power, switch faster, and operate at higher temperatures—essential characteristics for advanced computing applications. With major economies actively seeking supply chain diversification, Terrain's developing gallium resource represents a strategic opportunity in the critical minerals space.

Funding for Accelerated Development

To fund its ambitious exploration and development plans, Terrain has launched a rights issue aiming to raise up to $1.8 million. The offer, priced at $0.003 with 1:1 unlisted options (strike price $0.005, expiring 17 June 2027), closes on 17 June 2025.

This capital raise will primarily support:

• Follow-up drilling at the Smokebush Gold Project
• Metallurgical studies for the Larin's Lane Gallium Project
• Initial exploration at the Biloela Copper-Gold Project

Why Investors Should Watch Terrain Minerals

Terrain Minerals presents a compelling investment case for several key reasons:

With a market capitalisation of approximately $1.1 million, Terrain represents an early-stage opportunity in both traditional precious metals and critical minerals essential for the energy transition and advanced technology applications.

The company's strategic focus on commodities driving both the energy transition and improved living standards positions it well for the evolving resources landscape, while its exploration-to-production pathway offers multiple value-creation opportunities for investors willing to take on exploration-stage risk for potential substantial upside.
