(NYSE: VALE ) and Rio Tinto Group (NYSE: RIO ) to respond to rising demand, while also pushing further demand for materials such as fluorite from producers like Ares Strategic Mining Inc. (TSXV:ARS) (OTCQX: ARSMF ). A key ingredient in the making of steel, the issue of the fluorite (or "fluorspar") supply is integral to steel's resurgence. Earlier this year, price increases in China suggested a coronavirus supply disruption. Domestically, the only currently producing fluorspar mine is the Lost Sheep mine in Utah, owned and operated by Ares Strategic Mining Inc. (TSXV:ARS) (OTCQX: ARSMF ). The firm has begun investing in the upgrade of the Lost Sheep mine's facility, with expanded mine designs, and a new high capacity plant to significantly increase production capacity, make Ares the only domestic supplier of products such as acidspar and metspar.
