Macmahon Holdings Limited confirmed it has received a letter of intent in relation to the King of the Hills ("KOTH") gold project being developed by Red 5 Limited. The KOTH project is a major open pit and underground gold deposit located in the eastern goldfields region of Western Australia, with a projected mine life of over 16 years. Red 5 has commenced the construction of the camp and processing facilities on site and is planning for mining to commence in early 2022. First gold production is expected to occur in June 2022. Following a detailed tender process for both the surface and underground mining activities, Red 5 has issued a letter of intent to Macmahon for a proposal combining both scopes of work. Under the letter of intent, the parties are working to finalise the documentation by which Macmahon will provide all surface and underground mining services to the project over a 5 year contract term, commencing in the first quarter of 2022. Macmahon expects this documentation will be completed by June 2021 and that the contract will add over $650 million to the Company's order book.
