Fortuna updates on infill drill program at the Lindero gold Project in Argentina

Vancouver, September 6, 2018 -- Fortuna Silver Mines Inc. (NYSE: FSM) (TSX: FVI) is pleased to provide results for its infill drilling program at the Lindero Project in Argentina. The Lindero Project is under construction, and commercial operations are planned to start late in the third quarter of 2019, with an estimated gold production of 137,000 ounces of gold in the first full year of operation (Please refer to the Lindero Project Technical report dated October 31, 2017).

Eric Chapman, Vice President of Technical Services, commented: "Infill drilling has been carried out with the express intention of improving the confidence in the estimated tonnes and grade of material planned for mining in year one at Lindero. The mineralized intercepts encountered have met or exceeded our expectations in 44 of the 61 holes drilled when compared to estimated block model gold grades as of September 9, 2017." Mr. Chapman continued, "Of particular interest are the results for drill holes LDH-138, LDH-139, and LDH-164 associated with the mingled diorite porphyry unit in the center of the deposit, in an area which was previously thought to be non-mineralized. The new drilling results are presently being incorporated into an updated internal estimate of Mineral Resources and Reserves with the intention of optimizing the mine plan to capture the benefits of these new results.  Such updated technical information will not materially change the existing Mineral Resources estimates."

The infill drilling program, consisting of 61 diamond drill holes totaling 1,952 meters, focused on the areas planned for mining at Lindero in year one with holes ranging from 12 meters to 68 meters in length. The program was designed with three objectives: to improve the estimation of grades in mineralized areas with lower density of drilling; to better define the contact between mineralized and non-mineralized material at the periphery of the deposit and at the boundaries between lithologic units; and to source fresh samples for complementary metallurgical column tests on Mineral Reserves scheduled for year one. A map showing 2018 infill drilling collar location and a longitudinal section showing updated drilling and 2017 block model can be found at the following links, respectively: https://fortunasilver.com/site/assets/files/4406/lindero-infill-drilling-2018-collar-location-map_5sept18.pdf and https://fortunasilver.com/site/assets/files/4407/lindero-section-a-a-25m-width-updated-drilling-and_2.pdf.

Infill drill program highlights include:

LDH-138

  • 1.84 g/t Au over 42 meters from surface

LDH-146

  • 2.15 g/t Au over 20 meters from surface

LDH-164

  • 1.20 g/t Au over 66 meters from surface

LDH-186

  • 2.24 g/t Au over 28 meters from surface

LDH-187

  • 2.33 g/t Au over 24 meters from surface

The following table sets out the assay results for the infill drill program:

Notes:
1.  All holes drilled vertically
2.  The Lindero Deposit is a gold-rich porphyry with mineralization permeating throughout the deposit, making the calculation of true thickness impossible as no definitive across strike direction exists.

Quality Assurance & Quality Control

Following detailed geological and geotechnical logging, drill core samples are split on-site by diamond sawing. One half of the core is submitted to the ALS Global Laboratory in Mendoza, Argentina for preparation. The remaining half core is retained on-site for verification and reference purposes. Following preparation, the samples are assayed in the ALS Global Laboratory in Lima, Peru for gold by standard fire assay methods; for silver and base metals by ICP and atomic emission spectroscopy methods utilizing four acid digestion; and for cyanide soluble copper by atomic absorption methods. The QA-QC program includes the blind insertion of certified reference standards and assay blanks at a frequency of approximately 1 per 20 normal samples as well as the inclusion of duplicate samples for verification of sampling and assay precision levels.

About the Lindero gold Project

In September 2017, the commencement of construction at Lindero was officially launched (see Fortuna news releases dated September 21, 2017 and December 21, 2017). 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 existing mineral reserves. The initial capital cost budget estimate for the construction of Lindero is US$239 million, forecast to increase between 10% and 17% (refer to Fortuna news release dated August 7, 2018, “Fortuna provides construction update and reports initial on-site arrival of mine equipment at its Lindero gold Project in Argentina”); this amount does not include VAT which is expected to be recovered in the first 24 months from the start of mining operations. The technical report of the Lindero Project is available on SEDAR at www.sedar.com and on the Company's website at https://www.fortunasilver.com/site/assets/files/4098/lindero-project-technical-report-effective-date-31-oct-2017.pdf.
