In 2014, Brazilian operations produced 10-15 kilotons of Mg by this process.{{cite news |last1=Johnson |first1=MC |last2=Sullivan |first2=JL |title=Lightweight Materials for Automotive Application |url=https://publications.anl.gov/anlpubs/2014/09/107574.pdf |agency=Argonne National Laboratory |issue=ANL/ESD–14/7 |date=September 2014 |publisher=US Department of Energy}}
Also in 2014, Nevada Clean Magnesium announced its Tami-Mosi plan to create a ASTM B-92 pilot plant. The mineral resource is estimated at 412 billion tons of 12.3% grade Mg.{{cite news |title=Nevada Clean Magnesium Engages Silvertip Design NW to Design Pilot Reduction Furnace Design for Tami-Mosi Project in Nevada |url=https://investorintel.com/markets/technology-metals/technology-metals-news/nevada-clean-magnesium-engages-silvertip-design-nw-design-pilot-reduction-furnace-design-tami-mosi-project-nevada/?print=print |publisher=investorintel.com |date=19 February 2014}} The company produced its first ingot from a pilot plant in December 2018.{{cite news |title=United States Snapshot: Ten companies with projects on the go in the USA |url=https://www.northernminer.com/news/united-states-snapshot-ten-companies-with-projects-on-the-go-in-the-usa/1003804052/ |issue=4 |publisher=NORTHERN MINER |date=14 February 2019|volume=105 }}
