Summary:

The geology proximal to the Terakimti deposit comprises a northeast trending, central belt of intermediate porphyritic metavolcanic rocks flanked to the north by Neoproterozoic metasedimentary rock and granodiorite, and to the south by intermediate to mafic volcanic rocks. Significant chlorite, sericite, and silica alteration is associated with conformable gossanous horizons associated with the contact area of the intermediate and felsic volcanic rock packages, quartz-eye volcanic rocks and intrusive rocks are also present in this altered zone. The gossans are associated with polymetallic massive sulphide (gold- silver-copper-lead-zinc) mineralization at depth. Magnetic cherts are noted in the gossan area. The rocks have been affected by intense deformation, resulting in the development of a penetrative fabric in all lithologies, but in particular those rich in sericite. Local folding is present, but large- scale folds have not been identified.

The largest known economic occurrence on the Harvest property is the Terakimti deposit, a Neoproterozoic volcanogenic hosted massive sulphide discovery. Extensive drilling at 40 m by 40 m to 40 m by 80 m drill spacings (20 m by 20 m in oxide), it is currently defined as a moderate-sized relatively high-grade copper- gold-silver-zinc-lead occurrence containing multiple stacked lenses over 800 m strike and defined to depths f at least 260 m below surface. It is hosted within a bimodal volcanic sequence of intermediate and mafi ........

Summary:

An open pit mine plan has been completed for the Terakimti Oxide Project.

The PEA open pit contains the following oxide resources:

• 1,086 kt of potential mill feed
• 4,093 kt of waste rock (including mineralized material below cut-off grade)
• 110,000 tr oz of gold
• 799,000 tr oz of silver.

The pit shape follows the outcropping mineralised zone in a northeast-southwest orientation. The final pit designed for the PEA has three access areas, two on the eastern side of the pit as the main access from the process facility and one on the western side of the pit, which will be used for delivering waste to the WRD.

The Mineral Resource will be ripped where possible and with blasting expected to be required beyond a shallow free digging depth.

Hydraulic excavators (backhoe) and wheeled loaders will be used to load ore into trucks. The trucks will haul the material to a crusher on the south-east side of the pit. After crushing, the material will be loaded into a haul truck and transported to the heap leach facility.

Waste rock will be ripped where possible or blasted. Broken waste rock will be loaded into haul trucks and transported to an engineered WRD structure located approximately 120 m northwest of the pit.

This PEA considers open pit mining of the Terakimti deposit oxide zone. Mining will commence with stripping and stockpiling of topsoil and overburden, which will subsequently be us ........
