RareX Limited (ASX: REE) has announced a major step forward in its gallium re-assaying program at the Cummins Range carbonatite pipe, delivering the widest high-grade gallium intercept recorded at the project to date (Figure 1). This milestone follows a systematic re-assay of historical drill pulps from the 2020 infill program, aimed at unlocking the full critical metals potential of the deposit alongside its established rare earths and scandium resources.

30 June 2025 – Lightning Minerals Ltd (ASX: L1M) has announced a transformational acquisition of two advanced brownfields projects targeting gold and copper in Queensland  (Mt Turner Projects) and New South Wales (Lachlan Fold Copper Porphyry Project). The acquisition of Lotus Minerals Pty Ltd significantly strengthens the Company’s portfolio and introduces immediate drill targets in some of Australia’s most mineral-endowed regions.

Resouro Strategic Metals Inc. (ASX: RAU) is a recently listed company, having debuted on the ASX on 14 June 2024. While many early-stage mineral exploration companies spend their first year positioning and reshaping project narratives, Resouro has wasted no time in generating substantial technical momentum and government-level recognition.

When a company like Terra Uranium Limited (ASX: T92) steps beyond its uranium roots and into the high-stakes world of critical minerals, it’s worth paying attention. The latest move—acquiring the Glen Eden Project in New South Wales—signals more than just portfolio diversification. It’s a calculated entry into a sector underpinned by global strategic demand, rising prices, and tightening supply chains.

The narrative around critical minerals is no longer just a story of energy transition. It has become a complex intersection of economics, security, diplomacy, and market psychology. At first, it was about rare earths and lithium. Now the ripples have spread across copper, gold, iron ore, antimony, and more.

When it comes to development-ready assets, timing is everything. Larvotto Resources has just released a highly compelling Definitive Feasibility Study (DFS) for its Hillgrove Antimony-Gold Project in New South Wales—and it’s arrived at the right time. Gold prices are flying. Antimony prices are surging. Even tungsten is starting to catch a bid. Hillgrove is set to become a key player in a world hungry for critical minerals and strategic metals.

In my opinion, Tungsten should be one of the most critical metals on any investor's watchlist. The scarcity of the metal as an economical deposit, in my opinion, makes this metal high on the list. There are a few market factors that make Tungsten a very volatile commodity, and the China influence makes this metal difficult to predict in terms of its market value.

The pivotal role of critical minerals in the ongoing global transition toward clean energy and advanced technologies.
