Fortuna provides review of Brownfields exploration programs

VANCOUVER, British Columbia, Feb. 14, 2019 (GLOBE NEWSWIRE) -- Fortuna Silver Mines Inc. (NYSE: FSM) (TSX: FVI) is pleased to provide an overview of its Brownfields exploration programs in Mexico, Peru and Argentina.

David F. Volkert, Vice President of Exploration, commented, "An important exploration priority at Fortuna is to continue adding to the longevity of our mines. During the third and fourth quarters of 2017 and throughout 2018, the Company drilled a total of 62,412 meters in 134 surface and underground diamond holes at the San Jose and Caylloma mines and at the Arizaro Project, located within the Lindero Project concession block in Argentina.” Mr. Volkert added, “Fortuna is now working to incorporate the results of the Brownfields drilling campaigns at San Jose and Caylloma into the updated Mineral Reserve and Mineral Resource estimates for those mines, which are expected to be released next month.”

San Jose Mine, Mexico

Exploration drilling ahead of production is an ongoing program at San Jose that continued during the third and fourth quarters of 2017 and throughout 2018 totaling 50,904 meters in 105 holes with up to six drill rigs. A primary target was the Victoria mineralized zone, located 350 meters to the east of and sub-parallel to the Trinidad vein-Bonanza vein-Stockwork complex. Victoria is a blind discovery made in 2015 (see Fortuna news release dated August 12, 2015 ) consisting of a series of mineralized structures.

Full results for the underground drilling program consisting of 27,302 meters in 53 holes at the Victoria mineralized zone are listed in Appendix 1 . Drill highlights include:

SJOM781

• 119 g/t Ag and 0.57 g/t Au over an estimated true width of 13.5 meters

SJOM789

• 404 g/t Ag and 2.81 g/t Au over an estimated true width of 3 meters

SJOM794

• 213 g/t Ag and 1.24 g/t Au over an estimated true width of 6.3 meters

SJOM830

• 273 g/t Ag and 2.10 g/t Au over an estimated true width of 5.3 meters

SJOM833

• 217 g/t Ag and 1.72 g/t Au over an estimated true width of 7.8 meters

See Appendix 4 for full details of the additional San Jose drill holes completed during the third and fourth quarters of 2017 and 2018.

Following the successful exploration results for 2018, the Company has allocated US$4.5 million to continued Brownfields exploration at San Jose in 2019, including an estimated 11,500 meters of surface and underground diamond drilling and 450 meters of underground development for exploration drilling (see Fortuna news release dated January 17, 2019 ).

Caylloma Mine, Peru

Exploration drilling at Caylloma continued throughout the fourth quarter of 2017 and throughout 2018 totaling 9,330 meters in 17 surface diamond drill holes. Further to previously reported successful step-out drilling results at the Animas NE silver-polymetallic vein (see Fortuna news releases dated May 18, 2017 and October 11, 2017 ), drilling continues to intersect mineralized shoots ranging in size from 100 meters by 200 meters to 300 meters by 500 meters along strike to the northeast and at depth along the Animas NE vein. Step-out drilling is systematically completed outside of the present limit of the current Mineral Resource shell with drill holes spaced approximately 50 meters to 100 meters apart.

Full results for the Animas NE vein drilling program are listed in Appendix 2 . Drill highlights include:

ANIS052517

• 54 g/t Ag, 4.15 % Pb and 7.95 % Zn over an estimated true width of 7.2 meters

ANIS053817

• 25 g/t Ag, 2.37 % Pb and 4.04 % Zn over an estimated true width of 6.8 meters

ANIS062718

• 158 g/t Ag, 13.6 % Pb and 10.5 % Zn over an estimated true width of 3.7 meters

ANIS063318

• 87 g/t Ag, 2.51 % Pb and 2.19 % Zn over an estimated true width of 7.0 meters

ANIS063418

• 49 g/t Ag, 2.01 % Pb and 6.04 % Zn over an estimated true width of 3.5 meters

A longitudinal section showing the location of the step-out drill holes is available at the following link: https://fortunasilver.com/site/assets/files/4...e-vein.jpg .

The Company has allocated US$0.8 million to the continued Brownfields exploration program at Caylloma in 2019, which includes surface mapping and sampling of additional silver-base metal mineralized veins throughout the 36,000-hectare claim block (see Fortuna news release dated January 17, 2019 ).

Arizaro Gold-Copper Project , Lindero Camp, Argentina

The Arizaro Project is located within the Lindero mining concession, 3.2 kilometers southeast of the Lindero Project. While Arizaro is not included in the current Lindero mine plan it represents upside opportunity for Lindero if a satellite operation can be developed. Previous owners completed a total of 8,854 meters of drilling in 29 diamond drill holes over four campaigns carried out in 2002 and 2010-2013 and a historical resource estimation ¹ prepared in accordance with NI 43-101.

1. The historical resource estimate is included in a technical report entitled “Technical Report on the Arizaro Gold-Copper Deposit and Lindero Heap Leach Operation, Salta Province, Argentina” dated July 24, 2013 with an effective date of July 1, 2013 which was prepared for Goldrock Mines Corporation by Mine Development Associates and Kappes, Cassiday & Associates (the “Goldrock Report”), before the Company acquired the Lindero project. The historical estimate includes Indicated and Inferred Mineral Resources relating to the Arizaro deposit. The historical estimate was based upon assumptions contained in the Goldrock Report and uses categories as set out in National Instrument 43-101.  There has been no further Mineral Resource estimates conducted at Arizaro since July 1, 2013. Additional drilling was conducted at Arizaro in 2018 to improve the understanding of the geologic controls on mineralization and to verify assumptions used in the estimation of the historical estimate. There can be no assurance that the historical estimate will be updated. The Company has not verified as a current Mineral Resource or Mineral Reserve the historical estimate contained in the Goldrock Report, which was prepared before the Company acquired an interest in the property that contains the mineralization. Recent independent verification of the data has not been performed. A qualified person has not done sufficient work to classify the historical estimate contained in the Goldrock Report as current Mineral Resources or Mineral Reserves. The Company is not treating the historical estimate as current Mineral Resources or Mineral Reserves and the historical estimate referred to in the Goldrock Report should not be relied upon.

During 2018 Fortuna completed a surface core drill program of 2,178 meters in 12 holes to vertical depths of less than 200 meters aimed at identifying near surface porphyry-style gold-copper mineralization hosted in magnetite and biotite-rich breccia zones and in associated stockwork veins.

Full results for the Arizaro drill program are listed in Appendix 3 . Drill highlights include:

ARD32

• 0.61 g/t Au and 0.14 % Cu over 78 meters

ARD38

• 0.67 g/t Au and 0.16 % Cu over 52 meters

ARD41

• 0.70 g/t Au and 0.29 % Cu over 82 meters

Drill hole ARD41 is located approximately 350 meters west of previous drilling and represents a new zone that requires additional exploration.

Quality Assurance & Quality Control (QA-QC)

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 Lima, Peru, for samples from the Caylloma Mine, the ALS Global Laboratory in Guadalajara, Mexico, for samples from the San Jose Mine or the ALS Global Laboratory in Mendoza, Argentina, for samples from the Arizaro Project. The remaining half core is retained on-site for verification and reference purposes. Following preparation, the samples are assayed for gold and silver by standard fire assay methods and for silver and base metals by Inductively Coupled Plasma and atomic absorption methods utilizing aqua regia digestion at the ALS Global Laboratory in Lima, Peru, for samples from the Caylloma Mina and Arizaro Project and at the ALS Global Laboratory in Vancouver, BC, Canada, for samples from the San Jose Mine. 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.
