In April 2026, the Global Mining Power Rankings were topped by Rio Tinto in the large cap category, Resource Minerals International in the small cap category, and Sidney Resources in the microcap category. Geopolitical tensions, supply chain disruptions and changes in demand for raw materials have significantly altered investors’ priorities.
Market sentiment in April was determined by the conflict involving the United States, Israel and Iran. This has raised energy and logistics prices, disrupted supplies and increased volatility in key metals. Rising oil costs have increased operating costs across the economy, and shipping delays have tightened supplies, especially of aluminum and battery materials. Meanwhile, rising nickel and lithium prices and renewed expectations of a mining “supercycle” have supported industry optimism.
Among the major players, Rio Tinto took first place, receiving 17% of the votes. The company has increased copper production by 9% in the first quarter due to the Oyu Tolgoi mine in Mongolia reaching full capacity.
The second place was shared with it in terms of the number of votes, but lost in terms of capitalization to the Chinese Zijin Mining. It reported record results for the first quarter, with net profit up nearly 97.5% and revenue up about 25%. The company also presented a dividend policy for 2026–2028 with payment of at least 35% of profits.
Rounding out the top three was BHP, which earlier this month faced uncertainty over the potential refusal of Chinese steel mills to buy its products, but then struck a long-term agreement with the state-owned iron ore buyer, restoring access to the biggest market after seven months of disruption.
In the small-cap segment, Resource Minerals International was recognized as the best (14.3% of votes). Without major discoveries, the company is focused on advancing early exploration and strengthening its balance sheet. She reported encouraging geological indications of copper-molybdenum-gold mineralization, which will help refine targets.
In second place with the same result was Altius Minerals, whose forecast for royalty income for the first quarter of 2026 was about $26.4 million versus $15 million a year earlier. A portfolio growth to $70 million and new gold options in Nevada added to the outlook.
Third place was shared by Kaiser Aluminum and The Metals Company. Kaiser posted record first-quarter results and maintained its dividend, although insider sales of shares could make investors wary. The Metals Company ended April on a high after the National Oceanic and Atmospheric Administration deemed its deep-sea mining application fully compliant, pushing final permitting closer to early 2027.
In the micro-cap category, the leader was Sidney Resources (25% of votes). At the end of March the company published geophysical survey results, which identified an area-scale hydrothermal system at its Idaho project. The stock soared about 55% in two weeks in April.
Second place went to X-Energy (22.2%). The month was a turning point for the company: the company oversubscribed its IPO by almost a billion dollars at a price above its forecast range and successfully debuted on the Nasdaq. Large institutional purchases, including from ARK Invest, reflect strong demand associated with the development of nuclear power for AI. The same number of votes was received by Buyer Group International, which is continuing early metallurgical work and studying anomalous rhodium signals at its project in Wyoming.
Thus, the April rating clearly showed how geopolitics and industry shifts are redistributing investor interest: from giants with a diversified portfolio to bold small and micro companies betting on exploration and new technologies.
