Medallion’s acquisition and exploration program targets those REE potential-production and mineralexploration
projects that offer a reasonable solution to the two most critical REE-supply issues. These are:
1. a near-term shortage of REE supply, and
2. a lack of low-production-cost projects that can supply long-term sustainable REE supplies.
To solve the critical REE near-term-shortage and low-cost long-term supply issues, Medallion is focusing
on the mineral monazite as a near-term source and is seeking monazite processing partnerships and
purchase-agreements. The mineral monazite, an REE phosphate, was the world’s original source for
REEs. In the 1950s, with the discovery of the Mountain Pass mine in California, bastnaesite replaced
monazite as the leading REE source. Today, monazite and bastnaesite account for about 95% of the
world’s REE resources (roughly evenly split between the two minerals). Even at Mountain Pass, a
significant amount of the REEs are in monazite.
New REE production from monazite can be developed quickly and inexpensively because monazite is a byproduct
of heavy-mineral-sands mines around the world. The huge heavy-mineral-sands industry provides
the world’s main source of titanium and zirconium. Many of the mines maintain reserves in excess of one
billion tonnes, which translates into 20 to 40 years of production per mine. The by-product monazite from
just one of these huge mines could produce more REEs than most REE mines outside China.
By-product monazite does not require exploration, proving of ore, mining or most milling processes.
Monazite metallurgy is relatively simple, when compared to other REE minerals, and the metallurgical
processes have successfully produced commercial REEs for over 100 years. No other REE mineral, except
bastnaesite, has such a record of commercial success. These are significant cost-saving and time-saving
attributes.
Medallion also is targeting the acquisition of properties with ion-absorption-style REE occurrences. This
style of REE occurrence is often called the “South China Clays” model. At this time, the ion-adsorption
deposits in South China are the only known such occurrences; however, the necessary criteria, an
underlying geology with elevated levels of REE’s and a monsoon climate, are not difficult to match in
other areas of the world.
