Fortuna provides construction update at its Lindero gold project in Argentina

VANCOUVER, Feb. 20, 2019 - Fortuna Silver Mines Inc. (NYSE: FSM) (TSX: FVI) is pleased to provide an update on construction activities at its 100 percent owned Lindero gold Project located in the Province of Salta, Argentina.

Following the cessation of unusually heavy rainfall in Salta Province in recent weeks, which resulted in damage to the road leading to the Lindero Project site (see Fortuna news release dated February 7, 2019), management is pleased to report that the road has been repaired and on February 18^th the mobilization of personnel and materials to the project site resumed.

Mr. Jorge A. Ganoza, President, CEO and Director, commented, “Abnormal rains and electrical thunder storms not seen in a decade in the region are impacting our construction activities and schedule projections. A large amount of the float in the construction schedule has been consumed due to a slow start and ramp-up in excavations at the leach pad and crushing plant, key activities in the critical path of the project.” Mr. Ganoza continued, “As a result, we have had to revise our original construction schedule. Our plan now is to initiate ore stacking early in the fourth quarter of 2019, with first dore poured at year end and commercial production targeted for the first quarter of ­2020.” Mr. Ganoza concluded, “The Company remains well funded with low debt and sufficient liquidity to meet its construction and working capital requirements for the completion of construction activities and operating ramp-up activities at Lindero.”

Management has completed a thorough review of the project’s remaining construction schedule. Based on the progress of construction to date and the impact that abnormal rainfall has had on construction activities since late December 2018, the start of the summer season, the Company now plans to initiate ore stacking early in the fourth quarter of 2019 and is extending its guidance for achieving commercial production to the first quarter of 2020. The project team has had to overcome a slow start and ramp-up of activities from two key contractors involved in the massive earth excavations for the leach pad and foundation excavations for the crushing site; two activities that affect the critical path of the project. As of early February 2019, excavations for the leach pad and foundation excavations at the crushing site are 90 percent concluded and the activity has been de-risked. A slow build-up of camp availability has been another challenge for the project. Current on-site head count stands at 900 workers with a peak projection of 1,100 workers expected in April 2019. The construction camp has the capacity to host a population of 1,200 workers, de-risking contractor mobilization.

As of mid-February 2019, the overall project is 40 percent complete. Approximately 88 percent of direct capital costs have been committed and the total construction capital costs are forecast to increase to US$295 million or 20 percent over initial capital guidance (see Fortuna news release dated September 21, 2017). The revised construction capital costs forecast includes US$17 million for contingencies. The main drivers for the deviation are owners costs and construction indirect costs related to the extension of the project schedule, road maintenance and contractor stand-by costs due to abnormal rainfall impacting the project and access roads.

Construction Highlights:

• 18,750 tpd crushing and agglomeration plant
  All the crushing equipment manufactured by Weir has been shipped and received in the port of Valparaiso in Chile. The equipment is scheduled to be imported into Argentina and delivery to the project site will start in late February 2019. The crushing equipment includes a primary crusher, apron feeder, three secondary cone crushers, and three screens. The High Pressure Grinding Roll (HPGR), manufactured by Weir, arrived on site in December 2018. Two agglomeration drums have been shipped and are in transit to Argentina. Chutes, conveyors and steel structures are being fabricated in shops in Argentina and Chile with deliveries according to schedule.
  
  Excavation work for foundations at the crushing site is 95 percent complete. Civil works are currently underway with the building of retaining walls, placement of concrete at the HPGR site, and reinforced steel placement for primary and secondary crusher foundations. The HPGR site concrete placement, originally scheduled for November 2018, has suffered from delays due to an unexpected volume of rock mass encountered during foundation excavations.
  
  The crushing and agglomeration plant is on the critical path of the project. Commissioning of this plant is planned for late in the third quarter of 2019.

• Leach pad and pond area
  The excavations and ground preparation for the leach pad is one of the largest earth moving activities of the project, and one that suffered the most from contractor performance. The excavation of 1.2 million cubic meters of surface gravel and rock for ground preparation is 90 percent complete as of mid-February 2019. Approximately 15 percent of the start-up area for the leach pad is complete with liner, piping, and overliner installed. It is estimated that the leach pad start-up area will be ready to receive first ore by mid-2019 compared to the original estimate of March 2019.

• ADR and SART
  The procurement of all key equipment is well advanced. Concrete foundations for the ADR building and work on the equipment foundations is underway.
  
  It is planned that the ADR plant will be ready to receive solution in the fourth quarter of 2019.

• 8 MW power plant
  Once in operation, the mine power requirements will be self-generated through an 8MW diesel generator power plant. Power plant site preparation is complete and seven of twelve power generators have arrived at the project and have been placed at their site. The remaining five power generators are expected to arrive on site in the first quarter of 2019. Twelve transformers for the plant are planned to arrive by the end of February 2019 and ten 50 cubic meter fuel tanks are currently being installed for permanent operation. The power plant is scheduled to be fully operational by mid-2019.

• Construction camp and ancillary facilities
  The construction camp has the capacity to host a population of 1,200 workers. Peak head-count at the site is projected in April 2019 at 1,100 workers. Post-construction head count is estimated to be between 350 to 400 workers.
  
  Industrial water for the operation will be sourced from a 120 cubic meter per hour well field and pumping station located 13 kilometers from the project site. The installation of the 13 kilometer 8” water pipeline to the project site is planned to start in April with commissioning of the water system scheduled for mid-year 2019.

• Mine and equipment fleet
  All mine equipment required for the start of operations has arrived and has been assembled on site including; six 100 ton trucks, two 17 cubic yard wheel loaders, one 5 cubic yard crawler excavator, two 449 HP dozers, two 250 HP motor graders,­­ and two 800 HP rotary blast hole drill rigs. In December 2018, the operations team launched a heavy equipment operators training program for fifty candidates from local communities. The program and the selection of trainees is expected to conclude in March 2019.
  
  On-site road construction for large equipment and site preparation for mining is planned to start in the second quarter of 2019.

With Lindero in its first year of full production, Fortuna’s consolidated precious metals annual production¹ is expected to increase in 2020 to 190,000 ounces of gold and 9 million ounces of silver or 328,000 gold equivalent ounces². However, based on the successful results from the 1,952 meter year one in-fill drill program concluded at Lindero in September 2018 (see Fortuna news release dated September 6, 2018), management has initiated a review of the Lindero mine plan with the objective of capturing potential opportunities to maximize ounces of gold produced during the initial year. The results of the optimization study are expected to be announced in late March 2019.

__________
¹ Based on annual production plans for the life of the San Jose, Caylloma and Lindero mines
² Gold equivalent is calculated using a gold to silver ratio of 1 to 65 and does not include lead or zinc by-products

Further updates on the construction of the Lindero gold Project will be provided as the development of the project proceeds.
