High-Grade Vanadium Slag Mining & Processing in South Africa’s Bushveld Complex Region is Progressing as U.S. Vanadium Holding Company (USV) Signs 100% Offtake Agreement with Vanadium Resources Limited (VR8)

       Vanadium Resources Limited (VR8) has made a non-binding offtake agreement with U.S. Vanadium Holding Company LLC (USV) for 100% of the vanadium-bearing slag to be produced from its proposed next-generation V-Iron Plant, tied to the world-class Steelpoortdrift Vanadium Project in South Africa's Bushveld Complex. This comes as the U.S. is seeking to diversify its supply of vanadium away from China and Russia. Vanadium is used in industry, aerospace, and has military uses. Discovery Alert reported on the agreement and is the source of all the figures for this post. They note the importance of the project:

“USV's Arkansas refinery has confirmed via recent metallurgical testing that high-grade slags from South African VTM ores are well-suited to its processing flowsheet. Steelpoortdrift hosts 4.74Mt of contained V₂O₅, making it one of the largest vanadium deposits outside China and Russia.”

     VR8 is producing both pig iron and vanadium slag to diversify revenue and reduce exposure to vanadium price volatility. The development makes it possible that this source of vanadium will be a major supplier to Western markets.

     USV is the only integrated producer of high-purity vanadium specialty chemicals in the U. S, and operates a refinery in Hot Springs, Arkansas.

“Its product suite includes ultra-high-purity vanadium oxide (commanding a significant price premium), vanadium redox flow battery electrolyte, ferrovanadium, vanadium chemicals, vanadium oxides, and nitride vanadium.”

     In the past, USV processed high-grade vanadium-bearing slags from South Africa's Highveld Steel and Vanadium operations. While it no longer processes that source, it has been found to be well-suited to processing the vanadium-bearing slag from the Steelportdrift project. This aligns with USV’s goal of doubling its output of processed vanadium.

     This announcement indicates VR8’s move to a co-production model. Most vanadium production globally, about 70%, is as a by-product of iron smelting. VR8’s proposed process is as follows:

     The advantages of co-production over vanadium production alone are significant and given in the table below.

     Vanadium is a metal that increases the strength and durability of metal alloys while keeping overall weight low. It can withstand high temperatures and is resistant to shock. It is used in jet engine turbines, aircraft airframes, and armor plating for military vehicles and missile casings. About 90% of vanadium is used in the steel industry to increase the strength and durability of the steel. It improves earthquake resistance and is used in skyscrapers, bridges, and transcontinental pipelines. It is also used as the primary catalyst for producing sulfuric acid, the world's most widely used industrial chemical. It also has uses in fertilizer, detergent, and battery manufacturing.

     Below are some key details of the current non-binding offtake agreement. A binding agreement may occur in the future.

     VR8’s plans for the future of the project are detailed below.

     This deal is an important development for the U.S. and for South Africa. For the U.S., it represents a clear diversification away from China and Russia, which together control 93% of global vanadium supply.

     As detailed below, the resource and ore estimates were determined in a 2022 study by DFS. As noted, the recent favorable metallurgical testing at USV’s Arkansas facility makes it more likely that the project will be successful. Thus, the project is considered to be significantly de-risked.

"Vanadium Resources Limited has positioned itself as one of the most strategically relevant vanadium developers outside of China and Russia. With a binding offtake pathway into the United States, a world-class JORC resource, a proven co-production process route, and a clear set of near-term workstreams, VR8 is transitioning from exploration-stage asset holder to a credible supplier to Western critical mineral supply chains. Investors focused on critical minerals, resource nationalism, and Western supply chain security should be watching VR8's next set of milestones closely."
