GEOLOGY & MINERALIZATION
Gold oxide mineralization at the Fenix Gold Project is sub vertical and is of a bulk, disseminated style. It is controlled by NW-SE faulting and the gold mineralization occurs in Black Banded Quartz veins, hosted in complex breccias and bound by fault structures.
Based on the geological features observed, the project is classified as Low Sulphidation type of mineralization. The mineralization is 2,500 m long, up to 600 wide and up to depths of 600 m. The mineralization remains open at depth and to the North East.
Metallurgical studies indicate that gold is usually fine and occurs in both native form and as submicroscopic gold in iron oxides. Gold composition is of high purity which is on average > 99% Au.
The Fenix Gold Project mineralization is comparatively clean with trace occurrences of copper, sulphur and mercury, even at depths of 600m below the surface. This makes the Fenix Gold Project unique in the Maricunga region as it is a pure oxide gold deposit with no transitional or sulphide mineralization.

METALLURGICAL TEST WORK
Several metallurgical testing campaigns have been carried out on the Fenix Gold Project ore since 2010 in order to evaluate its metallurgical behavior in a conventional heap leach process. In addition, in 2017, some mineralogical studies, in the form of gold deportment, were conducted to explain the metallurgical results. This test work was undertaken by Kappes, Cassiday and Associates (KCA) and AMTEL Laboratories.
Cyanide leach tests were carried out through bottle roll and column percolation tests under different conditions of residence time and crush/grind size. Data used for the 2019 PFS, based on column tests, was performed on eleven composite samples. The tests were conducted at different crush sizes, from P80 of 100 mm to P80 of 9.5 mm, and at different residence times from 57 to 113 days and at different sample sizes from approximately 40 kg to 580 kg. All other conditions such as cyanide concentration and pH values were maintained equal for all of the tests. Conclusions from the tests are that gold extractions of 80% can be achieved, for material with a grade of 0.40 g/t Au and at P80 19 mm crush size. Test-work conducted in 2017 suggested that primary crushing (only) to 100 mm will produce 75% metallurgical recovery of the ore. Optimization studies of crush size/recovery vs capex are ongoing. Limited testing of material sized to 6” (150 mm) suggested that recoveries over 70% were possible.
In late 2020, Fenix Gold initiated activity with HLC (Heap Leach Consulting) and Farmesa Chile to obtain blasted material from each of the 3 pits, Fenix North, Fenix Central and Fenix South. Three blast projects of 500 m3 were drilled and shot to provide the material for a pilot ROM leach pad.
The material was excavated and blended at a ratio consistent with the 2019 PFS LOM contribution of the three pits. (18%/48%/34%). The amount of material placed of the pad for the ROM leach trial was 426 tons. The pilot trial was conducted at the Lince Plant site (25 km from the operation) at an altitude of 3,200 masl, using industrial water from the Nueva Atacama plant in Copiapo.
Sampling of the blended material gave a head grade of 0.464 gm/t, after completing 85 days of leaching, the leached material was resampled and returned a grade of 0.118 gm/t, indicating a recovery of 75%, consistent with the calculated recovery from solution grade and flow measurements.
The ROM trial heap demonstrated lime consumption was 2.95kg/t and cyanide consumption was 0.175 kg/t, both reductions over the PFS numbers.
A recent theoretical blasting fragmentation study by Farmesa (Chile) in August 2021 shows that a P80 of material passing 3 1/3” or 8 cm is achievable in Fenix Mineral, supporting the size distribution observed during the ROM leach trial.
Based on the results of the ROM trial heap, Rio2 have decided to remove the crushing circuit from the startup of the Project, reducing capital and simplifying the operation. Achieving 75% recovery from ROM, whilst removing crushing costs is an improved economic case from the 2019 PFS study. Ongoing test work and results from mining operations will determine if there is a case for introducing crushing in the future.

PROCESSING
High grade ROM ore will be mined and transported directly to the heap leach by trucks. Lime will be added to the trucks in route to the leach pad. Lower grade material is stockpiled for processing at the end of the Project’s life.
Processing operations will treat the solutions from the heap leach facility operating in a new ADR (adsorption, desorption and refining) plant capable of treating 20,000 tpd of ore to pad or 1,058 cubic meters per hour of pregnant solution to produce doré bars. The plant layout is designed to be upgradeable to 40,000 tpd and 80,000 tpd respectively.
Due to the removal of material re-handling, crushing circuit and lower ratios of lime and Cyanide required for the process there will be a reduction in processing costs originally estimated at $4.10/t for life of mine in the 2019 PFS.
GOLD EXTRACTION IN PILOT LEACH PAD

HEAP LEACH PAD
The leach pad area will be prepared and covered with an impermeable liner. Corrugated, perforated drainage piping will be laid on the liner for collection of the pregnant leach solution. A protective layer of finely crushed, permeable ore will be placed on top of the liner to prevent damage from the mobile equipment and during ore loading. The ore will be stacked on the pad in 10m lifts.
The pad will be developed in four stages with a stacking volume of 10.3 Mt for Stage 1, 30.6 Mt for Stage 2, 27.7 Mt for Stage 3 and 60.7 Mt for the final stage. The total pad capacity will be 129 Mt. The irrigation system will uniformly apply cyanide solution directly onto the levelled surface of the leach pile through a drip irrigation system, at an irrigation rate of 10 L/hm2 with an irrigation cycle of 90 days.
Once the mineral placed on the pad is saturated and in leach, the pregnant solution will drain to the base of the pad, and via gravity will be piped directly to the ADR Plant Adsorption Circuit. The PLS Pond will be built and used for storage of solution as required.
POWER
The power supply for the project will be generated through diesel generators. There will be 4 generators, 3 in constant use, and a 4th in standby for programmed maintenance.
Grid power is located within 25 km of the mine site and connection to the grid will be considered as the Fenix Gold Mine is expanded.
MINING
During Year 1 the mine production rate will be ramped up to 20,000 tpd of high-grade ore (> 0.40 g/t) for estimated gold production of 80,000 oz. The life of mine strip ratio (waste: ore) is estimated to be 0.81:1.
Mining will then progress for an additional 12 years at an average annualized rate of 20,000 tpd of high-grade ore and 7,000 tpd of low-grade ore and associated waste material. The high-grade ore will be sent to the leach pad whilst the low-grade ore is stockpiled for leaching in later years of mine life.
Mine design and estimation of the mining reserves was completed using conventional open-pit design methodology. The mine design is based on a $1,225 Lerchs-Grossmann pit optimization computer analysis.
The pit design incorporates 20m benches made up of 2 x 10m mining benches utilizing a fleet of 70 tonne and 90 tonne excavators and 43 tonne dump trucks. Mining operations will be performed exclusively by a mining contractor under a mining alliance style framework for the entire life of mine.

WATER SUPPLY
The 20,000 tpd project requires a water supply of up to 24 l/s. The Fenix Gold Project has access to water via a contract signed with Nueva Atacama, formerly known as Aguas Chañar S.A., the major water supplier to the town of Copiapo, to supply up to 20 l/s of treated town wastewater from its Piedra Colgada treatment facility located to the north of Copiapo. Additional water requirements will be topped up from the Lince water bore 5 l/s. The original plan, outlined in the 2014 PFS, was to build a pipeline with associated power line from the Nueva Atacama facilities to Fenix Gold along the existing main road, international road CH-31, from Copiapo to Argentina which passes within 20 km of the Project. This plan is still being considered for the future expansion of the Project and discussions are ongoing with infrastructure companies who are interested and able to finance and build the pipeline and other mining companies who may wish to share in the benefit of the pipeline project. The capital costs, operating costs and cost of water for the larger water solution are set out in the 2014 PFS.
The water for the 20,000 tpd project will be transported by 30 tonne capacity water tankers, loading from the Nueva Atacama facility and discharging to the process plant located at the Project, a distance of approximately 158 km. The water transport route will be via international road CH-31 which passes within 20 km of the mine site.
Water costs are estimated to be $1.56 per tonne of ore processed for the first four years of production and decrease to $1.51 per tonne for the remaining life of the project. The water cost includes the purchase price and transportation of the water to site.
The Company is currently reviewing a number of additional water options involving permitted, unused water rights which are closer to the planned mining operations with the objective of improving the economics of the water supply to the Project.

LABOR AND SUPPLIES
The Fenix Gold Project is located approximately 160 km from Copiapo, a mining town with a population of approximately 175,000 people that supports major mining operations in the area. Skilled labour, specialist services and materials for the mining operations will be sourced locally. An on-site camp for 400 people will be built for the mine operations whilst administration and logistics support will be located in Copiapo.
SOCIAL
Proposed mining activities at the Fenix Gold Project are located between 4.300m and 4.900m above sea level where the altitudinal and climatic conditions of the area impose natural restrictions for the establishment of human settlements, plants and wild animals, with predominantly arid soils.
The Colla Communities closest to the Project are located in Quebrada San Andres and Quebrada Paipote, where they carry out their main productive activities such as: animal breeding, grazing and agriculture (self-consumption), creation of handicrafts and medicinal herb collection. Occupations vary, according to each community’s perspective, as a reflection of their ancestral usage and current variants, mainly linked to ceremonial practices and transhumance practices.
