Kalgoorlie Nickel Project (KNP)

Western Australia, Australia · Open Pit

Under Development
NickelCobaltScandium
Overview
The Kalgoorlie Nickel Project (KNP), operated by Ardea Resources, is a significant nickel-cobalt project in Western Australia. Its main component, the Goongarrie Hub, is located approximately 70 kilometres northwest of Kalgoorlie-Boulder. The project has been awarded Major Project Status by the Australian Federal Government.
Production
Projected production from the Pre-Feasibility Study (PFS) estimates an output of approximately 30,000 tonnes of nickel and 2,000 tonnes of cobalt per year for more than 40 years.
Processing
Proposed processing for the Goongarrie Hub is based on a High Pressure Acid Leach (HPAL) flowsheet. A DFS update in December 2025 indicated a simplified, higher-throughput 3.5Mtpa HPAL-only flowsheet, including autoclave optimisation, designed to produce Mixed Sulphide Precipitate (MSP).

NickelCobaltScandiumRare Earth Elements
Overview
The Kalpini Hub is a collective name for a series of projects including the Kalpini and Bulong Nickel Projects, the Emu Lake nickel sulphide project, and the Yerilla Hub (Jump Up Dam, Boyce Creek and Aubils projects). It is focused on nickel and cobalt, with identified occurrences of scandium and Rare Earth Elements (REE). The resources are found in shallow, flat-lying nickel laterite deposits on ultramafic komatiite rocks.
Processing
Two potential processing methods considered: a standalone facility at Kalpini using High Pressure Acid Leach (HPAL) and Atmospheric Leach (AL), or hauling high-grade satellite feed to the proposed processing facility at the Goongarrie Hub.

Goongarrie South

Western Australia, Australia · Open Pit

Feasibility
NickelCobaltScandium
Overview
Goongarrie South is a nickel-cobalt-scandium deposit located in Western Australia, Australia. It is situated approximately 70 kilometres northwest of the city of Kalgoorlie-Boulder and is adjacent to the Goldfields Highway. The project is part of the broader Goongarrie Hub within Ardea Resources' Kalgoorlie Nickel Project (KNP).
Production

Feasibility
NickelCobaltScandium
Mine life
40 years
Overview
The Highway deposit is part of the Kalgoorlie Nickel Project (KNP) and is operated by Ardea Resources. It is envisioned that the Highway deposit will be a satellite open-pit mining operation. Ore is planned to be trucked 30 kilometres south along the Goldfields Highway to a central processing plant to be constructed at the Goongarrie Hub.
Processing
Proposed processing method involves a High-Pressure Acid Leach (HPAL) circuit, supported by an Atmospheric Leach (AL) circuit. Material from the Highway deposit is considered a key satellite plant feed source and is particularly noted for its suitability as an AL feed.

Overview
Bulyanhulu Gold Mine is an operational underground mine located in the Kahama district of the Shinyanga region in north-west Tanzania, approximately 55 kilometres south of Lake Victoria and 150 kilometres southwest of the city of Mwanza. It is a narrow-vein gold mine that contains gold, silver, and copper mineralisation in sulphides.
Production
Production overview - 2023: gold 180000 oz; 2021: gold 212000 oz.
Processing
The process plant has the capacity to process approximately 3,300 tonnes of ore per day. The processing methods involve a crushing and grinding circuit, a copper-gold-silver flotation circuit, and a Carbon-in-Leach (CIL) plant for gold extraction. The mine now produces gold bars on-site, having moved away from shipping concentrates for processing. A PhotonAssay laboratory was commissioned to improve mill feed. In 2024, a GlyCat (Glycine) project was implemented to reduce cyanide consumption by 80%.
Equipment
Bulyanhulu is an underground trackless mining operation. Mining methods include longhole sublevel stoping, conventional cut and fill, and mechanised drift and fill. The underground mine is accessed via a vertical shaft extending 1.1 kilometres deep and an internal ramp system from the surface.
Expansion
Barrick is focused on capital projects at Upper West and Reef 2. The Upper West boxcut was completed in mid-December 2024, and the decline portal has started, with the first ore expected by the end of 2025. As of July 2025, the development of the Upper West decline was well advanced. Excavation of the Reef 2 Upper East is planned to start in 2026 to access near-surface reserves. The current focus is on ramping up decline development to access the new Deep West mineral reserves and to define further exploration potential in Reef 2. In December 2021, Bulyanhulu acquired six prospecting licences in areas adjacent to the mine to potentially add significant mineral reserves.
