IT CONSISTS OF IRREGULARLY MIXED MASSES OF YELLOW AND REDDISH BROWN, POROUS LIMONITE, FREQUENTLY IN BOTRYOIDAL AND MAMMILLARY FORMS. THE BEST AND HARDEST ORE IS IN THE UPPER PART OF THE DEPOSIT. THE ORE OCCASIONALLY PASSES INTO A PURE YELLOW OCHER, IN SOME PLACES, BECOME CLAYISH WITH SEAMS OF BROWN AND RED CLAY. THE THICKNESS OF THE DEPOSIT IS VARIABLE AND IRREGULAR.
