Ore crushing and stacking

The ramp-up phase of the primary and secondary crushing circuits will involve an increase in production until nominal rates of 18,750 tonnes per day are achieved. The Company expects to achieve nominal rate production in the fourth quarter of 2020; inclusive of the tertiary HPGR system and agglomeration plant.

Ore stacking on the initial irrigation cell at the heap leach pad began on July 10. Heap irrigation is scheduled to commence at the end of August.

Ore for the commissioning and initial ramp-up of the crushing circuit and stacking on the heap leach pad is being sourced from the medium grade coarse ore stockpile inventory, of approximately 1.0 million tonnes averaging 0.55 g/t gold (refer to Fortuna news releases dated and ). During the period from July 2020 to December 2020, an estimated 1.7 million to 1.9 million tonnes of ore are scheduled to be placed on the leach pad with an average gold grade of 1.00 g/t to 1.10 g/t. The estimated stripping ratio during this period is 0.68 to 0.75 (refer to ).

Final construction activities related to the process ponds, ADR and SART plants continues with electrical and piping installations progressing according to plan.

About the Lindero gold Project, Argentina

In September 2017, the commencement of construction at Lindero was officially launched (refer to Fortuna news releases dated and ). Lindero has been designed as an 18,750 tonnes per day owner operated open pit mine with a pit life of 13 years based on current Mineral Reserves. Crushed ore will be placed on a leach pad with the pregnant solution pumped to SART and ADR plants prior to electrowinning and refining where gold will be poured to doré bars.

Management expects total construction capital expenditures of between $314.0 million and $320.0 million as per the updated construction and commissioning schedule (refer to ). This represents an increase of 28 percent from the September 2017 feasibility estimate. The technical report of the Lindero Project is available on SEDAR at  and on the Company's website at .
