Digest · Issue 003 · 7 September 2026

A magnet maker bought a mine, and nobody published the assay

USA Rare Earth closed on Serra Verde this week, which makes it the second American magnet company with a mine of its own — and the first whose mine is neither domestic nor bastnaesite. The completion release gives a tonnage for total rare earth oxide and no split at all, and the split is the entire question.

Peculiar Materials LLC · Covering 1 to 7 September 2026. What this issue skips, so nobody mistakes it for complete: prices, which move faster than a weekly can usefully report and are better bought from somebody whose whole job is assessing them; magnet research, which gets its own treatment when something actually ships; and exploration drilling, which tells you what is in the ground and not what anybody can make.

Published in arrears. This issue was assembled on 22 September 2026, from the archive and from the first full run of the crawlers, and not during the week it covers. Everything in it is dated to the document it came from rather than to the day I read it, which is the only honest way to run a back catalog that did not exist at the time.

Read it

The digest is free and goes to whoever asks for it. Put in the address you want it sent to and this issue opens in the same click — already on the list? The same box lets you straight back in.

Your address, the date and which page you came from. Nothing else, no tracking pixel in the email, one click cancels for good, and it is never sold, rented or shared. Mondays, when the mailing is switched on — I am not going to pretend it already is, and this line changes the day it does. Until then new issues appear here and in the feed. Prefer to give no address at all? The feed carries the same summary you are reading and tells me nothing.
