It was named after the Swedish village it was discovered in, Ytterby
for development of the Ytterby
project in Quebec, Canada.
Together with Quest, Matamec and GeoMegA, other companies active in rare earths are Vancouver-based Commerce Resources with its Eldor property where an initial 43-101 resource of significant size is already in place at the Ashram deposit; Ditem Explorations, working at its Lac Henri property in the Otish mountains; Focus Metals, in partnership with Soquem at their Kwyjibo IOCG property; and Midland Exploration, who have Japan's JOGMEC as partners at their Ytterby
project, located just a few km south of Quest's Strange Lake deposit.
Rare earth elements were first identified in a mineral unearthed from a quarry in Ytterby
, a small town not far from Stockholm, in 1787.
The moniker originates from their first discovery, in a so-called rare earth mineral (an uncommon oxide-type mineral) called gadolinite, in an abandoned mine outside the village of Ytterby
in Sweden by Karl Arrhenius, a Swedish army lieutenant and amateur mineralogy student, in 1787.
Gilbert first turned up as a dealer at Tucson in the 1970's; he literally had hundreds of flats of antique mineral specimens, mostly stacked in cubic closest packing under his tables and there would always be a small army of enthusiastic shoppers sitting in lotus-like contortions trying to find some rarity from Elba, Iveland, or Ytterby
A Finnish chemist, Johan Gadolin (1760-1852), studied a strange mineral that had been obtained from a quarry in Ytterby
In 1787 an artillery officer, Carl Axel Arrhenius (1757-1824), found a black mineral in the quartz and feldspar quarry at Ytterby
, northeast of Stockholm, which was shown by the chemist Johan Gadolin to contain a new "earth"--yttria.
The first three were named from syllables of Ytterby
, the quarry in Sweden where the first rare earth mineral had been obtained.
