Since 2007, all bromine production in the United States has been at Southern Arkansas’ Upper Jurassic Smackover Formation which contains the highest grade of bromine (5,000 to 6,000 ppm)

So tell me if I have read this incorrectly, but our bromine level is from table 1 in the announcement is 12,894 ppm is more than double.

Also:
The only producer of magnesium in the North America is US Magnesium LLC which produces magnesium from the brines of the Great Salt Lake, Utah. The magnesium concentration of the Great Salt Lake is 3.3% (33,000ppm).

and we show almost 43,000ppm
Just need to show quantity.
