Notes to Editors:

Horizonte Minerals plc is an AIM listed exploration and development company
focused on gold, silver and base metal opportunities in Brazil and Peru. It aims
to become, through experience and a track record of discovery success, to become
the preferred exploration partner for Major gold and base metal mining
companies, in the region.

The Group's has two flagship gold exploration projects in Brazil, a one
silver-zinc-lead project in Peru as well as additional gold, zinc and nickel
exploration projects in Brazil. The two Brazilian gold projects, Tangara and
Falcao, south of the highly prospective Carajas Mineral Province each cover an
area of approximately 300 sq km and are centred over greenstone belts, with
known gold mineralisation. The scale of these project areas, early results, the
overall aerial extent of the mineralised system and the high density and
magnitude of related gold anomalies, indicate the potential for multiple deposit
discoveries.

The El Aguila silver-zinc-lead project is located in the historic mining
district of Cerro de Pasco in Central Peru. Drilling has demonstrated the high
grade potential of this project. Additional projects include the 4,660 hectare
on the prospective Achaean aged Crixas greenstone belt, where multiple
nickel-copper anomalies have been defined and the 25,556 hectare Lontra Ni
Project situated in the Araguaia mobile belt, which flanks the eastern margin of
the Carajas Mineral Province of northern Brazil.
