Newmont — Oct 23, 2024 release

• Panel Cave 1-2 (PC1-2) is expected to produce 4.0 million ounces of gold and more than 700 thousand tonnes of copper over its fifteen year cave life (2027 - 2042). During peak production (2030 - 2040), PC1-2 is expected to ramp up to deliver between 275 and 325 thousand ounces of gold per year, and between 35 and 55 thousand tonnes of copper per year. The PC1-2 project is currently under review and a more fulsome update on the project's opportunities and metrics is expected to be provided in 2025. Development capital invested (excluding capitalized interest) since acquisition is $148 million, of which $123 million related to 2024. • In line with the development of the Cadia Panel Caves, Newmont's current focus is on maximizing existing tailings capacity, repairing the south wall of the Northern Tailings Facility and delivering the Southern Tailings lift. Newmont is undertaking long-term planning and design of its facilities to ensure that the tailings storage facilities are able to support the long mine life of Cadia. This work is intended to create capacity for the development of PC2-3, PC1-2, and future caves, setting up the next several decades of ore feed at Cadia.

Newmont’s global Closure Strategy integrates closure planning throughout each operation’s lifespan, aiming to create enduring
