Summary:
Mineralization in Pueblo Viejo is found in several separate deposits, including Moore, Monte Negro, Mejita, Cumba, and ARD1.
The Hatillo Formation hosts the limestone, which has been historically mined from the Quemados quarry and currently from the active Lagunas and San Juan quarries. There is potential for other limestone quarries to be developed towards the west of the MNFR.
All the lithologies at the Pueblo Viejo deposit are expected to have some argillic alteration with quartz, pyrophyllite and pyrite as the primary sulfide, minor sphalerite, local enargite with minor amounts of barite, rutile, telluride, and lead-sulfides. The other sulfides, sphalerite, and enargite (with some antimony replacing arsenic), are present with pyrite, mainly in veins and filling fractures.
Mineralization events are strongly related to the alteration sequence, with disseminated pyrite occurring in an early event and sulfide veinlets occurring in a later event. Mineralization has also been considered to have occurred during or close to the end of the sedimentation in the basin. The presence of typically centimetre scale subvertical mineralized veinlets cutting the bedding or hosted conformably in the deformed sediments (bedding plane continuity) are evidence of this. The density of these centimetre scale veinlets is directly related to gold grades, and form the trends required within the models. Sulfide veins can be found conformably hosted in the carbonaceous sediments experiencing post-deformation and others cutting across folded rocks.
Deposit Types
Pueblo Viejo is a Cretaceous high sulfidation epithermal gold, silver, copper, and zinc deposit. High sulfidation deposits have a high metal to sulfur ratio and are mainly characterized by minerals including pyrite, minor sphalerite, and enargite. The presence of pervasive and vuggy silica related to hydrothermal alteration is indicative of strong acid conditions. High sulfidation deposits are spatially related to volcanic centres and sometimes represent the upper levels of porphyry deposits, which for the Pueblo Viejo deposit, still requires further investigation.
Main Deposits
Pueblo Viejo is composed of several deposits; Moore and Monte Negro represent the main deposits along with small satellite deposits including Cumba, Mejita, and ARD1.
Moore
Moore forms the depocenter basement located at the southeast margin of the Pueblo Viejo deposit. The carbonaceous sequence is well developed with a thickness of more than 150 m. Mineralization is pyrite-rich, gold-bearing veins with an average width of four cm, steeply dipping with a trend typically to the NNW. There is a secondary pyrite vein set that trends N-S and N-NE. The orientation of pyrite veins and steep faults is similar.
Thin bedded carbonaceous siltstones and dacitic ash tuffs in the West Flank dip shallowly to the west. Dip increases towards the west where north trending thrust faults displace the bedding. Quartz veins with gold trend NW, oblique to the pyrite veins, have a similar strike to the interpreted contact with the overlying Hatillo limestone. They also occur as tension gash arrays in cm-scale dextral shear zones that trend north-northwest.
Faults create cm-scale displacement of bedding and pyrite-sphalerite veins occur along steep north- northeast trending faults. Two main NNE faults were mapped across the West Flank, sub-parallel to the Moore dacite pyroclastic contact. Displacement of veins preserves the evidence of lateral, sinistral movement.
Monte Negro
Monte Negro is located at the northwest portion of the Pueblo Viejo deposit. It is the distal area of the basin where the carbonaceous sequence is thinner and not as developed as it is in Moore. In the Monte Negro central area, pyrite-rich veins with gold mineralization are sub-vertical and have different trends creating conjugate sets; the average width is two centimetres. The north-northwest trending set is sub-parallel to the strike of the bedding and fold axes, indicating a possible genetic relationship between folding and mineralization. Enargite and sphalerite gold bearing veins trend dominantly to the north-northeast and have an average width of three centimetres. The combination of vein trends forms a high-grade gold zone which extends 500 m north-northwest, 150 m wide, and up to 100 m thick.
Mineralized veins in the south of Monte Negro are relatively pyrite-poor, sphalerite-rich, and show an average width of five centimetres. The veins are sub-vertical and trend NW. The episodic vein fill demonstrates a clear paragenesis (massive pyrite-enargite-sphalerite-grey silica).
Satellite Deposits
Cumba
The Cumba satellite orebody is located northeast of Monte Negro. The mineralization is hosted within an andesitic rock where a silicified orebody is developed and contains the main mineralization associated with pyrite, enargite, tetrahedrite and covellite with some sphalerite. The structural trend is northwest to east-west and seems to control the mineralization. A major structure trending northeast is limiting the mineralization to the south. Hydrothermal alteration is predominantly silica-pyrophyllite with traces of dickite in the center and illite-chlorite as the exterior envelope.
Mejita
The Mejita satellite orebody is located southeast of Moore. It is an extension of Moore, where the mineralization is hosted in the carbonaceous sediments (the upper part of the sequence) with some levels of dacitic pyroclastic rocks and a basement of andesitic flows. Mineralization occurs in the contacts between carbonaceous sediments/andesitic flows and pyroclastic dacitic/andesitic flows. Some deeper mineralization with high values of gold and silver is associated with a cruciform textured quartz vein with pyrite-sphalerite.
ARD1
The ARD1 orebody is located southwest of Moore. The mineralization is hosted in the carbonaceous sediments and the underneath polymictic volcaniclastics that are overlayed by the Hatillo limestone. The ore consists of pyrite and sphalerite veins that follow the bedding of the carbonaceous sediments. Hydrothermal alteration consists of a halo of advanced pyrophyllite with some dickite traces, surrounded by an intermediate argillic alteration.

Summary:
Current mine activity is in the Monte Negro and Moore pits. Mining is by conventional drill, blast, truck, and shovel methods.
The remaining pit only Mineral Reserves are estimated at 196.1 Mt of ore with a strip ratio 2.6:1. Total Mineral Reserves (pit plus stockpiles) are estimated to be 291.6 Mt at a strip ratio of 1.8:1. The combination of direct feed and stockpile re-handle is the current blending strategy at the mine. Ore blending for early processing of high-grade ore with consideration to sulfide content is practiced to maximize the NPV. Stockpile management and ore control practices are a key consideration.
The pit stages have been designed to optimize the early extraction of the higher-grade ore. Notwithstanding, the sulfur grade is an important consideration because the metallurgical aspects of the processing operation, the recoveries achieved, and the processing costs strongly depend on sulfur content in the plant feed, with benefits from consistency and low variability.
PAG waste rock from the pits is hauled to dedicated waste dump locations (currently the Hondo dump). From 2025 onwards, a crushing, conveying, and stacking system will transport and place PAG waste mined from the pit directly into the new Naranjo TSF. The PAG waste material deposited in Hondo is intended to be rehandled into completed pit void locations when available, and the remainder will be rehandled into the PAG handling system to the Naranjo TSF after pit mining is completed.
Mineral processing requires a significant amount of limestone slurry and lime derived from high quality limestone. Limestone quarries, located adjacent to the mine, have been in production since 2009 to supply material for TSF construction and the process plant.
Pit Design parameters
The final pit design is based on the following parameters:
• Bench height is 10 m with single and double benching by sectors.
• Main haul roads are designed with 35 m width and maximum 10% gradient.
• Roads within the carbonaceous sediments geotechnical domain are designed with a width of 40 m to account for residual geotechnical risk.
• In-pit single-lane haul roads (typically to within 3 x 10 m benches of pit bottom) have a design width of 20 m and a maximum gradient of 12%.
• The minimum mining width for phase design is generally targeted to be 60 m; however, locally can be narrowed to 40 m.
Quarries
Pueblo Viejo operations require significant amounts of limestone to operate the processing facility and construct the TSF facilities. PV exploits limestone resources adjacent to the gold and silver bearing pits to meet these requirements. PV utilises a Whittle type optimisation for guidance on the quarry designs and extents to maximise the resource extraction and minimise the mining costs.
Waste Dumps
As part of the closure requirements pertinent to environmental permitting, all PAG waste must be stored in anaerobic conditions to minimise the acid generating potential. This is typically achieved by co-disposing PAG and tailings in the TSF facilities but can also be achieved by backfilling the pits to an elevation below the natural water table level. Due to sequencing of the completion of the Lower Llagal TSF and the planned commissioning of the Naranjo TSF, there has been a necessity to store PAG in above-ground dumps temporarily. The PAG will be ultimately rehandled into in-pit voids and the Naranjo TSF.
Typical PAG waste dump design considers a 20 m bench height and a 14 m bench width. NAG waste dumps are designed considering final reclamation slopes and surface drainages for revegetation and closure.
The Hondo PAG dump has been designed to temporarily store over 150 Mt of PAG waste and low-grade ore. The key design considerations for this dump are ARD surface water runoff management and geotechnical constraints. NAG material is also stored onsite in conventional surface dumps and backfilled into mined-out quarries. NAG waste does not have the ARD considerations relevant to PAG waste.
Stockpiles
The mine design and scheduling strategy at Pueblo Viejo focuses on maximizing net present value. An levated cut-off grade strategy is employed where ore is mined at a faster rate than can be processed. The higher gold grade ore is preferentially fed to the process plant, while the lower grade ore is stockpiled.
Stockpiles are designed to be reclaimed in various phases throughout the LOM. A stockpile optimization was performed as guidance for the phase sequence. Typical stockpile design considers a 10 m bench height and a 7 m berm width.

Summary:
Existing Operation
The processing plant is designed to process approximately 24,000 tpd of ROM refractory ore. The oxygen supply is one of the key plant bottlenecks. The design basis for the oxygen plant is to provide the oxygen required to oxidize approximately 80 tph of sulfide sulfur. This is equivalent to 1,200 tph of feed containing 6.79% sulfide sulfur, assuming a design factor of 2.2 tonnes O2 per tonne sulfide sulfur.
The process plant consists of the following unit operations:
• Ore crushing circuit.
• SAG and ball mill with pebble crusher (SABC) grinding circuit.
• Pressure oxidation circuit.
• Oxygen plant.
• Hot cure circuit.
• Counter current decantation (CCD) wash circuit.
• Ferric precipitation circuit (partial neutralisation).
• Neutralisation and solution cooling circuit.
• Lime boil and slurry cooling circuit.
• Carbon-in-Leach (CIL) cyanidation circuit.
• Carbon acid washing, stripping and regeneration circuits.
• Refinery.
• Cyanide destruction circuit.
• Tailings effluent and acid rock drainage water treatment plant circuit.
• Tailings disposal facility.
The ROM ore is crushed to a P80 of 130 mm and ground to the optimum grind size of P80 of 80 µm in a SABC circuit. The SAG mill is in a closed circuit with a vibrating screen and a pebble crusher, while the ball mill is in a closed circuit with hydrocyclones. The cyclone overflow is thickened to approximately 50% solids and pumped to the autoclave feed storage tanks, which also serve to blend the ore to allow a more gradual and constant sulfur feed grade to the pressure oxidation circuit.
This ore slurry is pumped to the autoclaves to ensure an optimum reaction. The ore is oxidized for 60 min at a temperature of 225°C and a pressure of 3,100 kPag (500 PSIG). The oxidized slurry is flash discharged, and the steam produced is condensed in the quench tower and scrubber systems.
The oxidized slurry is sent to the hot cure tanks, where it is maintained at more than 90°C for 12 hrs. In this process, the basic ferric sulfate will be redissolved into the solution, which allows for a much lower neutralization cost using limestone. The cured slurry is washed in a three-stage CCD circuit to remove the dissolved metal sulfates and sulfuric acid from the slurry.
The washed slurry is pumped to the lime boil preheat vessel, which is reheated to 95°C using steam from the autoclave flash discharge. The reheated slurry is treated with lime and maintained at more than 85ºC to break down the jarosites to liberate silver. The lime boil slurry is then cooled to 50°C in a slurry cooling tower and pumped to the CIL cyanidation circuit, where gold and silver are extracted using cyanide and activated carbon.
The CCD wash thickener overflow, containing more than 99% of the dissolved metal sulfates and sulfuric acid, is used to condense the flash vapour in the autoclave quench systems and consequently contributes to reducing emissions to the atmosphere. The solution, at 95 to 100°C, is sent to the ferric iron precipitation tanks for partial neutralisation using limestone. The resulting slurry is pumped to and treated with limestone and lime in a high-density-sludge (HDS) neutralization circuit to precipitate the remaining metal sulfates. The sludge is thickened and pumped to the tailings facility after blending with the CIL tailings. The HDS thickener overflow is cooled in a series of solution cooling towers to less than 40°C and recycled back to the CCD wash circuit.
The lime and limestone required for the lime boil and neutralization process are produced on-site. Limestone quarries southwest of the open pits are developed to supply the required limestone for the process and TSF construction.
The limestone used for the process is first crushed in a gyratory crusher and then conveyed to a vibrating screen to separate the material between 50 mm to 100 mm, which will be suitable for the lime kilns. The finer and coarser materials are sent to the limestone grinding circuit, where it is ground in a SAG/ball mill circuit to produce a fine limestone slurry with a P80 of 60 µm used in the neutralization and ARD treatment processes.
Expansion Project
The Expansion Project is designed to both expand processing operations from 8.6 Mtpa to approximately 14 Mtpa to economically treat lower grade ore, as well as increase the tailings storage capacity at the asset, thereby increasing Mineral Reserves and extending the mine life. The intention is not to install an additional autoclave but rather to upgrade the low-grade ore by installing a flotation circuit and to modify the existing four autoclaves by including a flash recycle thickening circuit, which will assist in increasing the capacity and the residence time in the autoclaves. circuit and to modify the existing four autoclaves by including a flash recycle thickening circuit, which will assist in increasing the capacity and the residence time in the autoclaves.
The expanded plant will include the following:
• New gyratory crusher.
• Grinding (SS-SAG).
• Flotation.
• Flotation Tails CIL (FTCIL).
• Cyanide destruction.
• Vertical regrind mill for the limestone plant.
The following thickeners are being repurposed:
• Copper sulfide thickener is being repurposed to assist in the production of HDS.
• Iron precipitation thickener is being repurposed as the flash recycle thickener.
The following areas are being expanded:
• Ferric precipitation.
• Solution cooling.
• Limestone and Lime.
• Oxygen plant.
