Fortuna update on pre-commissioning and commissioning activities at its Lindero gold Project in Argentina

VANCOUVER, British Columbia, Dec. 23, 2019 (GLOBE NEWSWIRE) -- Fortuna Silver Mines Inc. (NYSE: FSM) (TSX: FVI) is pleased to provide an update on construction, pre-commissioning and commissioning activities at its 100 percent owned Lindero gold Project located in the Province of Salta, Argentina.

Jorge A. Ganoza, President, CEO and Director, commented, “Minor delays and unavailability of vendors due to holidays thwarted our best efforts to place ore on the leach pad prior to year end. Notwithstanding, primary and secondary crushing circuits are mechanically and electrically complete and are in the final stages of pre-commissioning.  This will be followed by commissioning of the primary and secondary crushers by placing ore in the crushing circuit.” Mr. Ganoza continued, “Tertiary crushing and agglomeration still require minor terminations in the areas of electromechanical and piping. Pre-commissioning of these facilities is now scheduled for mid-January, once vendor technicians return to site.” Mr. Ganoza added, “Main construction contractors will work through Christmas and break from December 28th to January 3rd. Mine operations and pre-production work continue non-stop.” Mr. Ganoza concluded, “We are currently in the final phase of a two year construction project in Argentina. Our engineers and management team continue to provide the outstanding leadership required to ensure completion of the project.”

Construction, pre-commissioning and commissioning highlights:

  • As of the end of November 2019, the overall project is 85% complete
  • Primary and secondary crushing circuits: Pre-commissioning activities are being carried out and are in their final stages; placing of first ore to crushing is scheduled for the end of December
  • HPGR circuit: Final mechanical completion activities and vendor representative unavailability through the holidays have pushed back pre-commissioning activities to mid-January 2020
  • Agglomeration plant: Mechanical installation is complete and minor piping and electrical installation work is in the final stages; pre-commissioning is expected to commence in mid-January 2020
  • Power generation: 8 MW power plant and medium voltage power distribution system have been commissioned
  • Substations and electrical rooms: Crushing circuit, agglomeration plant substations and electrical rooms have been commissioned
  • Industrial water supply: Water wells and pumping system have been successfully tested, and the 13 kilometer water pipeline to the project site is being pre-commissioned

18,750 tonnes per day crushing circuit and agglomeration plant

Primary and secondary crushing circuits are mechanically and electrically complete. Equipment is in the final stages of pre-commissioning and will be ready to receive ore at the end of December 2019. At the tertiary crushing circuit, acid wash of the HPGR's hydraulic and lubrication systems has concluded and oil flushing of the systems is being carried out. Final mechanical adjustments and pre-commissioning of the tertiary crushing circuit will commence once vendor representatives return from the holiday roster rotation in the second week of January 2020; commissioning is expected by mid-February.

At the agglomeration plant mechanical installation has been completed and electrical installation is in its final stages. Substation and electrical rooms have been energized. Piping installation at both, cyanide preparation and agglomeration plants, is being finalized; pre-commissioning is expected in January 2020.

Operational readiness and pre-production mining     

As of the end of November 2019, the operational readiness plan implementation is proceeding according to plan and is 90 percent complete. Mine, maintenance, processing area, and logistics procedures have been completed. All key personnel for the operation are on site. Training for mine operators has been completed and processing area operators are finishing their training programs. Main supplies and consumables for the operation have been listed and are integrated into the logistics purchase program.

In early September 2019, pre-production mining at the Lindero deposit commenced. The owner operated mining fleet is performing according to the operation's ramp-up plan achieving an average mining rate of 21,000 tonnes per day during November. The Company will provide an initial conciliation between ore mined and the geological block model in January 2020.

Assay laboratory

Sample preparation and analysis for gold using fire assay with an atomic absorption finish (FA-AA) commenced at the temporary on-site laboratory in mid-October 2019 before transferring to the permanent on-site facility.  A comprehensive Quality Assurance/Quality Control (QA/QC) program has been instigated, which includes the insertion of standards, blanks, and duplicates to monitor laboratory performance.

About the Lindero gold Project, Argentina

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 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.

The initial capital cost budget estimate for the construction of Lindero as set out in the technical report entitled “Fortuna Silver Mines Inc.: Lindero Property, Salta Province, Argentina” dated effective October 31, 2017, including Year 3 investments advanced to pre-production, is forecast to increase to US$298 million, an increase of 22 percent over what was budgeted in the technical report; this amount does not include value added tax 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 and on the Company's website at
