The Toroparu Deposit, Main, and South East areas are representative of an Archean gold (±copper) intrusion related system (Kontak, Katz, & Dubé, 2012) (Katz, Kontak, Dubé, & McNicoll, 2015) (Mathieu, Crépon, & Kontak, 2020). It closely resembles other structurally controlled, mesothermal gold systems seen in Archean greenstone belts such as the Abitibi or the Yilgarn craton. It appears genetically similar to deposits such as Côté Gold, Lac Doré, Boddington and Las Cristinas. Deposits of this type are closely associated with intrusive suites with geochemical signatures of rocks derived from hybrid melts (high heavy rare earth element, abundance of intermediate units, low- to moderate water content) (Mathieu, Crépon, & Kontak, 2020). They include porphyry copper-gold, syenite-associated disseminated gold, and reduced gold-bismuth-tellurium-tungsten intrusion related deposits, as well as stockwork disseminated gold. It is thought that this could be a result of the overprinting of two different deposit types. The Sona Hill Deposit represents an orogenic lode gold deposit and is related to the gold ± copper system at the Toroparu Deposit.

Toroparu Deposit, Main, and SE Areas
The Toroparu Deposit mineralization is oriented in a west-northwest direction with cross-cutting eas-twest mineralized structures. The system corresponds to a 2.7 km long and 200 m to 40 m wide body and extends to over 400 m in depth. The mineralized body occurs along the northwestern boun ........

The Project will be mined using open pit methods for the initial part of the extraction and in year 10 an underground mining method will be started. Both mining methods will continue to the end of the life of the asset.

Open Pit Mining
A conventional truck-shovel method was considered for the open pit portion of the Toroparu Deposit. The open pit analysis results in several distinct open pits coalescing into the NW and Main Toroparu Pits over time. The Sona Hill and Southeast Zone (SE) will be developed in a similar fashion beginning in year 3 and 6 respectively. The final dimensions of the NW Pit are approximately 990 m long x 690 m wide x 360 m deep. The dimensions of the Main Pit are approximately 1,300 m long x 750 m wide x 470 m deep. The open pit LoM plan proposes to mine approximately 93 Mt at a cut-off grade of 0.5 g/t Au and 558 Mt of waste rock material. The average stripping ratio for the open pit operations is 6:1 over the LoM. Each pit is currently planned to be developed with 29 phases each. Compacted saprolitic waste material will be used to construct haul roads, facility pads and flood control berms, levies, and other structures.

The PEA mining plan includes the Main, NW, SE and Sona Hill Pits. The Main, NW and SE pits are located within the Toroparu Deposit and the Sona Hill Pit is located within the Sona Hill deposit. The SE pit is located 1 km southeast of the Main and NW Pits and the Sona Hill Pit is located approximately 5 km ........

The concentrator is designed to process 14,000 tonnes per day (tpd) of mineralized material (nominal) during its peak operation. The processing plant will be constructed in two phases. The first phase consists of the initial 5 years of the Project where the plant will receive Low Copper
Ore (LCO) and saprolitic material to recover Au at a nominal throughput of 7,000 tpd. During the second phase, the plant will be expanded with the addition of a 7,000 tpd Cu flotation circuit and the associated equipment to process Average Copper Ore (ACO) and produce a Cu concentrate. The overall plant capacity will double in size to 14,000 tpd with the addition of the flotation circuit.

Phase 1 processes 7,000 tpd of LCO and saprolite material through crushing and grinding, carbon in leach (CIL) circuit and adsorption, desorption and recovery (ADR) to produce Au doré. This phase continues through the LoM. Sona Hill material will also be processed during this period.
