Brazilian ‘Garden of Gold’

There is an old maxim in the mining industry that says, “Mines are where you find them”. To put it another way, you cannot change the location of geological deposits. This is frequently unfortunate for all involved and, almost inevitably, takes exploration and mining companies to wherever the best economic mineral deposits can be found, whatever the challenge. Such a quest has recently taken London-listed Serabi Mining plc (Serabi Mining) to the Tapajos region of northern Brazil. The Tapajos was the location of a major artisanal mining gold rush from the early 1970s to the late 1990s. During this time, it has been estimated that up to 30 million ounces of gold may have been extracted, making it one of the largest gold regions in the world. However, despite these figures, this exciting area has been poorly explored to date.

The Tapajos region is situated in the Central Amazonian Province, within the Amazon Craton, and is mainly of Proterozoic age. The gold deposits have various geological settings but, amongst these, a dominant NW-SE fracture zone some 100s of kilometres long and about 50km wide is particularly important. Serabi Mining has secured an extensive land position and identified a number of targets along 70km of this zone, in addition to other Tapajos projects. Geological potential also exists for very large, low-grade gold and copper deposits of the porphyry and IOCG (Iron Oxide Copper Gold) types.
