Project Overview

An Early-Stage Gold Development in Northern Ghana

The Zongoiri Gold Project (ZGP) is a pre-construction stage gold development located in Ghana's Upper East Region. The project is situated within the Paleoproterozoic Nangodi Greenstone Belt — part of the Birimian geological province that hosts several producing gold mines across Ghana and neighbouring Burkina Faso.

The project covers a total concession area of approximately 157.5 km², covered by a granted Mining Lease. The project is currently being advanced toward construction based on a Pre-Feasibility Study (PFS) undertaken by a Ghanaian Qualified Person (QP) consultancy.

The PFS outlines a processing plant designed to treat free-milling Birimian gold mineralisation typical of the Nangodi belt, using gravity recovery followed by cyanide leaching.

Geology

Geological Setting

Regional Geology

◆Metavolcanics and metasediments
◆Porphyritic granodiorite intrusions
◆Regional shear structures related to Birimian tectonics

Gold Mineralisation

◆Occurs primarily in sheared granodiorite and altered volcanic rocks
◆Consistent with gold styles observed elsewhere in the Birimian belt
◆Mineralized zones form multiple steeply dipping lenses that remain open along strike and at depth
