Snapshot	The Nkosuo deposit is located approximately 7 kilometres north- northwest of the Edikan Gold Mine in Ghana and added substantial Mineral Resources and Ore Reserves to Edikan at 30 June 2022. Early in FY23, Perseus Mining announced the completion of the Nkosuo Feasibility Study, which was submitted to the Ghanaian Minerals Commission with an application to include land covered by the current Exploration Licence to Perseus’s existing Nanakaw Mining Lease (“ML”). A proposed enlargement of the Nanankaw ML to incorporate a portion of the western arm of the Agyakusu Prospecting Licence (“PL”), which includes the Nkosuo deposit, was approved by the Minister for Land and Resources. This is an important milestone in the delivery of the Nkosuo deposit into the Edikan Life of Mine (“LOM”). Planned processing of the Nkosuo Ore Reserves in the Edikan mill is expected to increase the life of the Edikan operation by 18 to 24 months.

Summary:

The Nkosuo project is an addition to the Edikan group of gold deposits that occur near the western flank of the Ashanti Greenstone Belt in south-western Ghana. The regional geology of the Edikan property is underlain principally by Paleoproterozoic Birimian metasediments of the Kumasi-Afema basin, positioned between the Ashanti and Sefwi Greenstone Belts.

The Nkosuo prospect is a granite-hosted orogenic gold deposit similar to several deposits exploited at Perseus’s nearby Edikan Gold Mine. Edikan gold deposits occur near the western flank of the Ashanti Greenstone Belt along the Obuasi-Akropong gold corridor. The Central Ashanti property is underlain principally by Paleoproterozoic Birimian metasediments of the Kumasi-Afema basin, positioned between the Ashanti and Sefwi Greenstone Belts. The flysch type metasediments consist of dacitic volcaniclastics, greywackes plus argillaceous (phyllitic) sediments, intensely folded, faulted and metamorphosed to upper green schist facies. Minor cherty and manganiferous exhalative sediments are locally present, and graphitic schists coincide with the principal shear (thrust) zones. Numerous small Basin-type or Cape Coast-type granitoids have intruded the sediments along several regional structures. Structurally controlled gold mineralisation occurs in two principal modes: disseminated pyrite-arsenopyrite mineralisation associated with quartz veining and sericite alteration hosted by granitoids and shear-zone hosted mineralisation associated with pyrite-arsenopyrite mineralisation in and adjacent to quartz veins in deformed metasedimentary rocks.

The Nkosuo deposit comprises mineralisation hosted by a single NNE striking granitoid body measuring at least 600m along strike, typically 250m horizontal width and dipping approximately 75° toward WNW. Drilling has confirmed that the body is continuous to at least 350m vertical depth below surface. The entire granite is not mineralised throughout but drilling to date indicates substantial zones of gold mineralisation up to 100m horizontal width.

The Nkosuo Mineral Resource model extends for 675m strike length and up to 240m width. Indicated Mineral Resources extend to 150-170m vertical depth; Inferred Mineral Resources extend to 300-325m vertical depth.
