Mining Operations
Golden Cities
The Golden Cities is located within the Paddington mining and exploration tenement package. Norton Gold Fields currently operates two active mines in the area: the Havana Open Pit and the Federal Underground Mine. It is 100% owned and operated by Norton Gold Fields and is centred around the Paddington Mill, located 35km North-West of Kalgoorlie, Western Australia.
Geology
The Golden Cities mining lease includes five deposits: Havana, Federal, Jakarta, Mt Jewell, and Mulgarrie. Gold mineralization in this area is linked to Archean orogenic tectonic and metamorphic events, specifically regional D2–D3. All deposits are part of the Norseman-Wiluna greenstone belt, characterized as ductile shear zone-type gold deposits, with gold sourced from granitoid complexes and deep hydrothermal activity.
Havana, Federal, and Jakarta are located within the Kalgoorlie Terrane’s Boorara Domain greenstone belt, inside the Scotia-Kanowna granite/granodiorite dome. Gold is primarily found at intersections of northeast to north-northeast trending faults with northwest-trending faults, associated with demagnetization of the dome’s granite.
The Mulgarrie deposit is on the eastern limb of the Scotia-Kanowna batholith anticline. Its structural trend is north-northwest to south-southeast, aligned with the greenstone stratigraphy of the Boorara Domain. Mineralization is mainly controlled by a northeast-dipping thrust fault along the contact zone of komatiite/high-Mg basalt within brittle shear zones in carbonate-altered lenses, with low greenschist facies metamorphism.
Federal Underground
The Federal deposit is located 12km north-east of the Paddington mill, situated within the Golden Cities camp area which includes the Havana deposit.
The Federal Operation is an Owner Operated Operation using optimised scheduling techniques and modern underground fleets to mine over 0.35 Mtpa of ore.
In February 2025, the Federal underground mine successfully cut the portal.
Havana Open Pit
The Havana deposit is located 12km north-east of the Paddington mill, situated within the Golden Cities camp area.
The Havana Operation is a 100% Owner Operated Operation using optimised scheduling techniques and modern truck and shovel fleets to mine over 0.6Mtpa of ore.
The Havana project recommenced in Aug 2025 and currently has a planned life of mine of 4 years with the potential of prospects to extend the life of mine as well as exploring underground opportunities.
Carbine-Zuleika
The Carbine-Zuleika region is located approximately 40 km west of the Paddington Processing Plant and comprises several key deposits, including Bullant, Wattlebird, Matt’s Dam, Porphyry and Breakaway Dam. The project provides an important resource development and exploration opportunity within Norton’s broader Kalgoorlie tenement portfolio.
The Bullant underground project was acquired from KMC during 2013, in 2025 it has an annual ore production of over 245,000 tonnes, producing 21,500 ounces of gold.
Geology
The Carbine-Zuleika Operation is located within the northwest-trending Coolgardie-Carbine Archean greenstone belt. The primary structure in this area is a gently dipping, northwest-trending syncline composed mainly of sedimentary rocks, felsic volcanic rocks, and minor mafic/ultramafic intrusions from the Black Flag Group. Gold mineralization typically occurs along geological contact zones, particularly between mafic and ultramafic units.
Bullant is situated along the Zuleika Shear Zone, a prospective regional north-northwest trending structure. The Shear Zone is a broad ductile to brittle structural corridor contained within a mafic unit in the mine area. The Shear Zone dips sub-vertically to steep east dipping.
Bullant Underground
The Bullant Operation is an owner operated underground mine. Our In-House Production and Engineering Teams collaborate to extract over 0.3 Mtpa of Ore from the Bullant Deposit using sub level stoping techniques.
Mt Pleasant
The Mt Pleasant Project consists of 21 deposits, including key deposits such as Tuart, Racetrack and Golden Kilometre. The project is characterised by high-grade, narrow-vein gold mineralisation and remains an important part of Norton’s ongoing resource development pipeline.
Geology
The Mt Pleasant Projects area is located within the Ora Banda region of the Archean Kalgoorlie Terrane, bounded by the Zuleika Shear Zone to the west and the Abattoir Shear Zone to the east.
The Tuart deposit comprises a series of high grade quartz-carbonate-sulphide brecciated or laminated veins hosted within mafic volcanics. Supergene oxide mineralisation is developed in the regolith immediately above and/or adjacent to the primary veins. Mineralisation covers a broad area located to the northwest of the Homestead underground mine, and immediately west of the historically mined Quarters open pit and underground mine.
Tuart Underground
Each year, Our Contractor Production Team and both In-House and external Engineering Teams collaborate to extract over 0.6 Mtpa of Ore from the Tuart Deposit using sub level stoping techniques.
Ora Banda
The Ora Banda Project comprises several deposits, including Enterprise, Gimlet South and Slippery Gimlet.
Ora Banda has historically been an important mining project for Norton and continues to represent a prospective area for resource development and exploration. The project has strong drilling upside, with potential to extend known mineralisation and support future resource growth.
Geology
The greenstone sequence in the Ora Banda mining area consists of thick ultramafic and mafic volcanic rocks, overlain by intermediate to felsic volcaniclastic rocks and sediments.
Geological control on the Enterprise deposit comprises the intersection of an east-west trending structural corridor with a stratigraphically favourable south-west dipping dolerite sequence.
Enterprise Underground
Each year, our Contractor Production Team and both In-House and external Engineering Teams collaborate to extract over 0.4 Mtpa of Ore from the Enterprise Deposit using long hole sublevel stoping techniques.
Processing Plant
Paddington Mill
The Paddington Mill, located 35km north of Kalgoorlie, remains the central hub for Norton’s gold processing operations in the Goldfields region.
Since acquiring the Paddington Operations in 2007, Norton has operated the mill at high levels of availability and utilisation. This consistently high level of performance is a testament to the planning, dedication and innovation of our metallurgical, processing and maintenance teams.
Paddington Mill is a conventional SABC processing plant with a throughput capacity of 4.0 Mtpa. It treats a blend of open-pit and underground ore, with gold recovered through gravity and carbon-in-pulp circuits. The process includes gyratory crushing, SAG and ball milling, pebble crushing, gravity recovery, cyanide leaching, carbon adsorption, elution, electrowinning and smelting to produce gold doré. The plant achieves an average gold recovery of 92%.
