Last month, Medallion Resources (MDL.V) announced it successfully completed additional test work aiming at producing a cerium-depleted REE concentrate. This is a major step forward for the company as the low-value cerium was dragging down the total value per kilogram of REE concentrate.
Now the new test results and flow sheet have indicated it is indeed possible to substantially reduce the cerium content from the REE concentrate. This increases the ratio of magnet metals in the final concentrate, and those magnet metals are the real money makers.
