Our Projects

Meridian Mining SE is focused on the acquisition, exploration, development and mining activities in Brazil. The Company is currently focused on exploring and developing the Espigão polymetallic project, the Mirante da Serra manganese project and manganese portfolio assets and the Ariquemes tin exploration portfolio in the state of Rondônia.

Espigão Polymetallic

Following the recognition of a zoned polymetallic hydrothermal system at Meridian’s Espigão Project, the Company has progressively integrating multi-element data consolidated during five years of manganese operations, with high-quality aerial geophysical datasets The Company is refocussing its efforts on evaluation of the copper-gold exploration potential due to

  • The widespread copper anomalism in the oxide vein systems;
  • The presence of two significant gold in stream and soil anomalies at the Project; and
  • The age range and geochemistry of the crystalline basement (consistent with Proterozoic Cu-Au provinces such as the Gawler Province of Australia)

Espigão Polymetallic page



Focusing on exploring for paleo-channel and primary tin deposits within the world class Ariquemes tin field, located in Rondônia, NW Brazil, a state rich in natural resources and under-explored. The project area hosts the “right rocks” and a favourable geophysical signature for targeting repeats of the mineralization. While the magnetics imagery provides focused areas for targeting concealed intrusions for disseminated / stockwork target styles. In house reviews of structural modelling provides focused areas for targeting vein / pegmatite mineralization.
