Based on a comprehensive review of the Company’s portfolio of assets following the Newcrest acquisition, the Company’s Board of Directors approved a portfolio optimization program to divest six non-core assets and a development project in February 2024. The non-core assets to be divested include Akyem, CC&V, Éléonore, Porcupine, Musselwhite, Telfer, and a development project in Canada. In February 2024, the Company concluded that these non-core assets and the development project met the accounting requirements to be presented as Held for Sale in the first quarter of 2024, based on progress made through active sales program and management’s expectation that the sale is probable and will be completed within 12 months. |

Summary:
The Akyem mine is an orogenic gold deposit that has oxide and primary mineralization.
The Akyem deposit is localized in the hanging wall (upper side or plate) of a regional fault that trends to the northeast (N70°E) parallel to regional structures and dips to the southeast (S60°E) parallel to the foliation developed in a Birimian host rock. The planar fault structure (thrust fault)[11,12] is intensely sheared and exhibits a mylonitic to cataclastic fragmental texture consisting of lens of metavolcanic fragments in a matrix of sheared and plastically deformed graphitic material. The presence of graphitic rubble zones suggests reactivation of the fault zone over time. The fault occurs in fine grained, gray green massive to locally sheared Birimian mafic metavolcanic rocks exhibiting chlorite and carbonate alteration that locally contain euhedral magnetite. Immediately overlying the metavolcanics is a distinctive gray green pink unit containing blue quartz phenocrysts in a mylonitic matrix (quartz epiclastic rock). The upper and lower contacts of this unit are typically sheared and brecciated, and the upper contact of this unit is locally in sharp contact with overlying light gray tan chert. This unit is considered sedimentary and represents a distinctive marker between the metavolcanic and metasedimentary units of the Birimian. The overlying metasedimentary rocks are for the most part turbidite sequences consisting of graywacke, argillites, black carbonaceous siltst ........
Summary:
Akyem, located in Birim North District of the Eastern Region of Ghana, approximately 80 miles (125 kilometers) northwest of the national capital city of Accra, is an open pit mining operation comprised of two mining leases issued under the Ghanaian Mining Act, encompassing an area of approximately 16,000 acres (6,000 hectares).
The mining method at the Akyem mine involves removal of ore and waste rock from an open pit mine. The open pit is an elongated structure consisting of a large western lobe (Main Pit) and a small eastern lobe (East Pit), connected near the surface.
Mining is conducted using large scale conventional hard rock drill and blast open pit methodology. Run of Mine (ROM) ore is trucked from the pits using CAT 785 DT’s.
