Fortuna Silver Mines Inc. (NYSE: FSM) (TSX: FVI) is pleased to announce that step-out and infill drilling at the San Jose Mine has established continuity of high-grade mineralization in the upper levels of the Trinidad Footwall structures. The successful drill program was conducted from the second half of 2020 to date, representing 4,670 meters of step-out and infill drilling in 22 drill holes and targeted both resource upgrades and the potential to expand the resource outside of the current area of Mineral Reserves. Mineralization remains open in at least two directions, is adjacent to existing mine infrastructure, and as a result there is potential for inclusion of this material in near-term production.
David F. Volkert, Vice President of Exploration, commented, “In 2020, our exploration team at San Jose focused on re-evaluating their understanding of the structural and geological controls on mineralization at the Trinidad Deposit with the goal of identifying new near-mine exploration targets.” Mr. Volkert continued, “The interception of wide and high-grade mineralization in close proximity to current production areas at the mine reflects the structural complexity of the deposit and unveils discovery potential remaining at the San Jose Mine.”
Step-out drill highlights include:
SJOM-955: 699 g/t Ag and 3.57 g/t Au over an estimated true width of 4.1 meters
SJOM-1002: 1,931 g/t Ag and 6.76 g/t Au over an estimated true width of 5.4 meters
Infill drill highlights include:
SJOM-1014: 306 g/t Ag and 1.38 g/t Au over an estimated true width of 9.5 meters
SJOM-1016: 760 g/t Ag and 3.24 g/t Au over an estimated true width of 3.4 meters
SJOM-1017: 967 g/t Ag and 4.25 g/t Au over an estimated true width of 8.4 meters
SJOM-1020: 809 g/t Ag and 2.78 g/t Au over an estimated true width of 1.4 meters
SJOM-1021: 473 g/t Ag and 1.25 g/t Au over an estimated true width of 14.9 meters

Full details of the 22 step-out and infill drill holes completed in the Trinidad Footwall structures are listed in the appendix section at the end of this news release.
The Brownfields exploration program budget for 2021 at the San Jose Mine is US$10.9 million, which includes 33,800 meters of diamond drilling and 1,770 meters of underground development for drilling access, platforms, and services. Underground exploration drilling will focus on the shallow and deep north and south extensions of the Trinidad vein system and the sub-parallel Victoria mineralized zone, while surface drilling will test two new targets to the south and north of the mine.
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 Guadalajara, Mexico. 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 at the ALS Global Laboratory in Vancouver, BC, Canada. 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.
