The Coronation and Coronation North deposits are located 5 to 6 km to the northeast of the processing plant. Coronation consists of a 15 to 20 degrees dipping hangingwall shear that is between 3 and 10 metres thick. Immediately beneath (1 to 10 metres) the hangingwall shear is a thinner lode structure that parallels hangingwall. Unlike deposits to the south, there is very little development of stockwork mineralisation beneath the hangingwall. Mineralogically, the Coronation deposit is very similar to previously mined deposits to the south. Located 1km to the north of Coronation is the Coronation North deposit which was discovered in 2015. Coronation North differs from most of the previously mined ore bodies along the HMSZ. Pit mapping and grade control data have delineated a left-hand lateral bend in the strike of the HWS coincident with a high-grade zone of mineralisation that plunges to the ENE. Traversing along the shear from southeast to northwest the dip of the HWS gradually decreases whereas the strike bends towards the west. This bend coincides with a zone of steeply dipping en-echelon style mineralised splays beneath the HWS, whose dip steepens to near vertical as they approach the FWF. Zones of finely laminated mineralised quartz veins also form beneath this WSW-striking segment of the HWS, perpendicular to its strike. Compared to the other deposits in the goldfield, the WSW-strike of Coronation North, the relatively narrow approximately 100m width of the mineralised zone and its steep dip are currently unique in the goldfield. At the Frasers open pit and FRUG, deposits are centred on mining the hangingwall shear. In outcrop, the shear typically dips at 15 to 20 degrees to the east and is approximately 5 metres thick. At depth, the dip of the shear flattens to approximately 5 to 10 degrees and develops into an approximately 20 to 30 metres thick mineralised high-grade zone of quartz cataclasite, and mineralised schist. Within the open pit, gold mineralisation comprises mineralised schist and cataclasite, shear-parallel quartz veins and arrays of sub-vertical quartz veins. hangingwall shear and arrays of subvertical quartz veins account for most of the mineralisation within the open pit, although there are a few shear-parallel quartz veins. These veins typically splay off the base of the hangingwall Shear and dip at between 5 and 10 degrees to the west. A large amount of erratic mineralisation occurs between the base of the hangingwall shear and the footwall fault. At the resource drilling stage, this mineralisation manifests as poorly developed clusters of elevated gold grades, which often appear discontinuous. During mining however, these typically present as extensive zones of quartz vein arrays and mineralised shears. The footwall fault lies between 80 metres and 120 metres below the hangingwall shear and is identified as a cataclastic zone up to 10 metres thick. To date, no economic mineralisation has been located below the footwall fault. Mineralisation The Macraes deposit is a classic example of an orogenic style gold deposit, with mineralisation broadly synchronous with deformation, metamorphism, and magmatism during lithospheric-scale continental-margin orogeny. Most orogenic gold deposits like Macraes occur in greenschist facies rocks. Orogenic deposits typically formed on retrograde portions of pressure-temperature time paths during the last increments of crustal shortening, and thus postdate regional metamorphism of the host rocks. The following four types of mineralisation occur within the HMSZ at Macraes: (a) Mineralised schist. This style of mineralisation involves hydrothermal replacement of schist minerals with sulphides and microcrystalline quartz. Mineralisation is accompanied by only minor deformation; (b) Black sheared schist. This type of schist is pervaded by small scale anastomosing fine graphite, and sulphide bearing microshears. This type of mineralisation is typically proximal to the hangingwall shear; (c) Shear-parallel quartz veins. These veins lie within, and/or, adjacent to the black sheared schist and have generally been deformed with the associated shears. The veins locally crosscut the foliation in the host schist at low to moderate angles. Veins are mainly massive quartz, with some internal lamination and localised brecciation. Sulphide minerals are scattered through the quartz, aligned along laminae and stylolitic seams. These veins range from 1 centimetre to more than 2 metres; and (d) Stockworks. These veins occur in localised swarms that are confined to the intrashear schist. Individual swarms are up to 2,000 square metres in area and consist of numerous subparallel veins. Most of these veins formed sub perpendicular to the shallow east dipping shear fabric of the intrashear schist. Stockwork veins are typically traceable for 1 metre to 5 metres vertically with most filling fractures that are 5 centimetres to 10 centimetres thick but can be up to 1 metre thick.

Conventional open cut bench mining methods are used at the Macraes Goldfield. Pits are excavated on level benches 2.5m high within the ore zone (approx. 2.8m high after blasting) and 4m high within the waste zone.

Hydraulic backhoe excavators in the 250t and 360t class are used for mining ore and waste. Ore is mined with different techniques depending on the style of mineralisation.
- Hanging wall lode ore is mined by first removing the hanging-wall waste with an excavator under visual control of a geological technician, then mining the exposed ore. Footwall ore is selectively removed from the underlying footwall waste if it can be visually controlled, otherwise the footwall ore is diluted with the wedge of underlying waste; and
- Stockwork ore is generally mined within the defined ore blocks. Ore blocks are defined with the guidance from a conditionally simulated grade control model.

With this mining method and equipment, the smallest selective mining unit (SMU) used when defining ore blocks is 4m by 4m by 2.5m high (approximately 100t), but blocks are generally a minimum of 500t to minimise dilution.

Mining to date at Macraes has come from thirteen pits comprising (from north to south), Coronation North, Coronation, Deepdell North, Deepdell South, Golden Point, Northwest Pit, Round Hill, Southern Pit, Innes Mills, Innes Mills West, Frasers, Golden Ridge and Golden Bar. Current operations are based in Coronation North, Deepdell North, Gay Tan and Frasers West pits. The Round Hill, Innes Mills and Southern pits were mined to what were their economic limits. Round Hill and Innes Mills pits were subsequently backfilled, and Southern Pit was used for tailings disposal. Following updated geologic interpretation and economic analysis, as part of its ongoing program to convert Mineral Resources to Mineral Reserves at Macraes, the Company has added these deposits back to its Mineral Resources and Mineral Reserves.

The bulk of the future open pit tonnage from Macraes will be sourced from Frasers West, Gay Tan 3 and 4, Deepdell North, Innes Mills, Round Hill and Golden Bar deposits.

Mineralisation has also been outlined to the north at the Nunns/New Zealand Gold & Tungsten, Longdale, Mt Highlay and Mareburn deposits, and to the south at the Taylor’s, Wilson’s, Shaw’s and Ounce deposits. Further drilling programs are required to upgrade these deposits.

Open pit mining at Macraes is carried out by Company personnel using owned mining equipment. Ore concentration is carried out at the Macraes site by Company personnel. A standard refining contract is in place for the transportation and refining of the doré bullion into fine gold.

The current life of mine plan for the Macraes Mining operations ends in the fourth quarter of 2028 with processing completing in the fourth quarter of 2030. Based on the current drilling program, it is possible the Company will extend the LOM plan if additional Mineral Reserves are defined in the interim.

The plant's crushing and grinding comprises the following components and stages:

- Two single stage jaw crushing circuits, which reduce the ore to a top size of approximately 200mm; the products from these two circuits are directly fed to the two SAG mills and an emergency feeder on the conveyor system feeding the higher capacity circuit provides continuity of feed to the grinding circuit if the jaw crusher feed is interrupted;

- A complex grinding circuit to reduce the particle size of the ore to 80% passing at 130 µm; the original, higher capacity crushing circuit feeds a 2,300kW SAG mill and the new crushing circuit feeds a 1,500kW SAG mill; discharge from the two SAG mills is combined with the discharge from one of the two ball mills (2,300kW) and directed to the primary cyclone cluster. Discharge from the higher capacity ball mill (2,500kW) is fed to the secondary cyclone cluster. The underflows from both cyclone clusters are combined and fed in parallel to the flash flotation circuit and two ball mills (2,300kW and 2,500kW);

- Regrind of the flotation concentrate is performed in a 900kW ball mill to 80% passing of 15 µm to improve pressure oxidation kinetics.

The Macraes Process Plant recovers gold by concentrating the metal into a relatively small fraction of flotation concentrate, oxidising the reground concentrate in a pressure oxidation autoclave, washing the oxidised residue and then utilising a carbon-in-leach process to recover gold from the residue.

In detail the plant comprises:
- A flash flotation circuit made up of roughing and cleaning stages. The circuit is fed from the circulating load of the grinding circuit via cyclone underflows to recover the bulk of fast floating sulphide minerals containing high gold content in the coarser size fraction;

- The main flotation circuit made up of roughers, scavengers, cleaners, recleaners and cleaner scavenger flotation cell trains to produce a gold bearing sulphide concentrate at optimum sulphur grade for the downstream pressure oxidation circuit;

- Limestone is added to the regrind circuit discharge to control net acid generation in the pressure o ........
