Research published in Nature Climate Change urges governments to direct low-carbon hydrogen toward uses where it can cut emissions at lower cost. Comparing ten high-emitting sectors around 2035, researchers identify steelmaking, refining and ammonia production as priority applications. Conversely, hydrogen in road and rail vehicles appears less competitive than direct electrification under the assumptions studied.

The United States and Nigeria have announced a cooperation framework intended to deepen US investment in Nigeria’s mining sector. Presented on the sidelines of the United Nations General Assembly in September, the arrangement covers exploration, geological data, deposit development, processing, infrastructure and technical capabilities. It forms part of closer ties between Washington and Abuja and the global competition to secure critical minerals.

Namibia wants to change the relationship between mining investors and national resources. President Netumbo Nandi-Ndaitwah is calling on foreign companies to build processing and manufacturing facilities in the country, so minerals are no longer exported raw before being bought back as processed products. The direction is clear: access to subsurface resources must contribute more to industrialization, employment and local skills.

Fortuna Mining’s latest drilling results at Diamba Sud broaden exploration prospects for the Senegalese gold project without, by themselves, changing its economic status. The campaign intersected several mineralized intervals beyond Southern Arc’s currently modeled outlines, while drilling began at Bambadji, a recently acquired neighboring license. Laboratory assays from this second area are still awaited.
