Our Operations

Nechí Alluvial Property - Colombia

Long History of Efficient, Profitable & Reliable Production.
Asset Description

  • Operations centred near the town of El Bagre, 190 km north of Medellín, Colombia with an excess of +10 years of reserves based on LOM plan.

  • 49-years dredging experience of well-understood, efficient, profitable and reliable production with suction and bucket dredges similar to mineral sands operation.

  • Alluvial Au deposits mined from closed ponds in the floodplain adjacent to the Nechí River as free Au is hosted in sand and gravels with no use of cyanide and mercury as the Au recovery process is done through only gravity turned.
