Meyas Sand Gold Project (MSGP) is situated in the far north of Sudan, approximately 75km south of the border with Egypt, and is fully permitted by the Sudanese Government with a Mining Lease, Royalty agreement and a water permit formally granted incorporating attractive fiscal terms.
Following the outbreak of armed conflict in Sudan between the Sudanese Armed Forces and the Rapid Support Force, Perseus withdrew most of its employees from the MSGP site pending resolution of the conflict, as safety of its staff is the Company’s number one priority. The Final Investment Decision on MSGP development, initially scheduled for the second half of 2023, was subsequently deferred until confidence in the overall safety and security of the country is restored. |

Summary:
The mineralisation types being targeted within the Block 14 Project are broadly categorised into 3 groups, namely, Orogenic Gold, Volcanogenic Massive Sulphide, and Rift Associated Epithermal.
Evidence of orogenic gold mineralization is present throughout the project area. It is generally associated with narrow gash veins, shear type veins and quartz veinlet swarms in well foliated schistose rocks within the volcano-sedimentary domains which are intruded by stocks and sheets of diorites, syenites and granitoids.
The geological framework of Block 14 is dominated by two distinct geological domains - the andesite dominated Gabgaba terrain of the Arabian Nubian Shield (ANS) to the east and the marine sediments of the Keraf Suture in Western Gabgaba; these are separated by the Eastern Gabgaba Fault System (EGFS). The central part of the licence is dominated by the Northern Gabgaba Graben, a downthrown portion of the Keraf that has been infilled by clastic sediments.
Galat Sufar South (GSS)
The GSS deposit is located in the central portion of the Galat Sufar Andesite Domain. The GSS deposit is located just south of the contact between marine sediments to the north (a remnant of the Keraf sediments) and an andesitic volcanic sequence to the south. The andesitic sequence is heterogeneous comprising lava flows, pyroclastic deposits and primary volcanic breccias.
Of importance to deposit formation, the andesite sequence contains a discr ........

Summary:
Given the gold grades and proximity to surface, the deposits will be mined via a conventional truck and excavator open pit mining method. The Wadi Doum deposit will be exploited through a single pit approximately 130 m deep. The GSS deposit will be exploited by eight separate pits, six of which are shallow oxide / transitional pits with minimal fresh material. The other two pits (East and Main) are approximately 260 and 270 m deep respectively.
A total of 79.9 Mt of crusher feed at a gold grade of 1.11 g/t is contained within nine pits across the two deposits, along with 119.2 Mt of waste, resulting in a strip ratio of 1.49:1.
Based on the assumed mining equipment, a bench height of 5 m was used, although geotechnical conditions allowed for up to four benches to be excavated between safety berms, depending on the material. There may be some opportunity to mine higher bench heights in areas of bulk waste where grade control and mining dilution do not need to be considered.
A combined mining schedule demonstrates that a processing rate of 6.0 Mt can be sustained for 14 years, including an initial ramp up period in Years 1 and Year 2. A pre-production period of six months is utilized to strip waste from both deposits and stockpile minor amounts of crusher feed, ready for the commissioning of the processing plant. The pit at WD is mined for the first five years and blended with material from GSS. An elevated cut off grade over eight years maximise ........
