Serro Do Caldeirao, Pontes e Lacerda, Mato Grosso, Brazil Mining in the greater Mato Grosso region dates back to the mid 1500s. Gold was first discovered in the Cuiabá Basin in 1718, and the town of Poconé owes its origin to a gold rush which occurred during the late 1770s. Mining activity declined dramatically following the end of the 18th century, and it wasn't until the early 1980s that gold exploration began again in earnest throughout the region. The present specimen originates from a find made only last year. It exhibits robust crystals to the reverse side and herringbone crystallization to the front. It is exemplary of this limited new Brazilian find. The present robust specimen has a triangulated form, with a set of herringbone pattern crystals at the base. Weighing approximately grams ( ozt) and measuring 28.74 x 19.29 x 9.46mm
