Kalkine’s “Global Critical Minerals Report” provides an overview of the minerals driving the global energy transition and advanced technologies. The report examines key regions including Australia, Canada, the United States, and the United Kingdom, covering the value chain from mining and refining to battery, semiconductor, and defence manufacturing.

The report analyses strategic raw-material supply chains and geopolitical resource positioning across global markets, highlighting how access to critical minerals is increasingly shaping national security, industrial policy, and economic competitiveness. It also evaluates the critical minerals value chain across upstream mining, midstream processing and refining, and downstream manufacturing, where supply concentration and processing bottlenecks continue to influence global supply dynamics.

As demand from electric vehicles, renewable energy infrastructure, AI hardware, and defence technologies continues to rise, governments and corporations are strengthening supply security through mining investments, strategic partnerships, and the development of domestic reserves. While the sector faces challenges such as long project development timelines and commodity price volatility, structural demand and supportive policy initiatives are expected to drive long-term growth across the critical minerals sector.
