following link: https://www.fortunasilver.com/site/assets/files/4102/animas-ne-vein-step-out-
drilling_6oct17.pdf
Step-out drilling has been carried out below the present limit of the estimated Mineral
Resources with drill holes spaced approximately 50 meters to 100 meters apart in two different
locations over areas covering 150 meters and 700 meters along strike and 150 meters and 300
meters down dip, respectively . The mineralized intercepts show that the Animas NE vein
remains open along strike to the northeast and southwest and at depth.
The Caylloma Mine and processing plant currently operate at a capacity of 1,470 tpd with 2017
annual production projected at 1.0 million ounces of silver, 30 million pounds of lead and 41
million pounds of zinc . The operation is expected to process 535,000 tonnes of ore averaging
71 g/t Ag, 2.73% Pb and 3.86% Zn (see Fortuna news release dated January 11, 2017 ). The
Brownfields exploration budget for 2017 is US$3.9 million, which includes 22,000 meters of
diamond drilling of which 18,700 meters have been drilled through mid-September.
In the second quarter of 2017, mine production was sourced mainly from the Animas NE and
Animas Central areas with each contributing 57 % and 3 3 % of ore , respectively (see Fortuna
news release dated July 13, 2017).

The San Jose Mine and processing plant currently operate at a capacity of 3,000 tpd with 2017
annual production projected at 7.1 million ounces of silver and 51,900 ounces of gold. The
operation is expected to process 1,050,000 tonnes of ore averaging 230 g/t Ag and 1.67 g/t Au
(see Fortuna news release dated January 11, 2017 ). The Brownfields exploration budget for
2017 is US$7.0 million, which includes 31,000 meters of diamond drilling of which 18,045
meters have been drilled through mid-September 2017.

In the second quarter of 2017, mine production was sourced from Trinidad Central and Trinidad
North with each area contr ibuting 60% and 40% of ore, respectively (see Fortuna news release
dated July 13, 2017).
Arizaro Project, Lindero Camp, Argentina
It is management’s view that Arizaro presents the opportunity for a contributing satellite
deposit, adding economic benefit to the Lindero mine once in production. The Arizaro gold -
copper porphyry is located within the Lindero concession, 3.2 kilometers southeast of the
Lindero Project.
Historic work has included regional and local mapping, trenching with surface rock -chip
sampling (27 trenches, 6,568 meters, 495 samples) and drilling (8,854 meters, 29 core holes).
Highlights of drilling completed over four campaigns in 2002 and 2010 into 2013, include:
ARD-13
• 0.61 g/t Au and 0.22% Cu over 168 meters, including 1.81 g/t Au and 0.40% Cu over
30 meters
ARD-21
• 0.43 g/t Au and 0.17% Cu over 339 meters, including 0.66 g/t Au and 0.18% Cu over
94 meters
ARD-24
• 0.64 g/t Au and 0.24% Cu over 160 meters, including 0.82 g/t Au and 0.26% Cu over
104 meters
Note: Estimated true widths are not applicable at Arizaro due to the porphyry style of mineralization
Since August 2016, Fortuna has completed the following work at the Arizaro project aimed at
identifying high-grade gold resources that can materially add economic benefit to the Lindero
Project:
1. Relogged 8,817 meters (29 drill holes) of historic core - similar geology, alteration
and mineralization are found at both Lindero and Arizaro.
2. Remapped (1:2,000 scale) the entire surface area from immediately southeast of
Lindero to and including the area of historic drilling at Arizaro.
3. Submitted 321 samples from historic core pulps for cyanide-soluble copper analyses,
which will be used as a precursor to designing possible future metallurgical testing
and subsequent, shallow drilling at Arizaro.

Greenfields Exploration Update
Lindero concession and other properties in Salta, Argentina
Exploration work to date on the Lindero concession has been focused on outcropping porphyry
mineralization at the two known porphyry systems: Lindero and Arizaro. Alteration zones and
silica structures located within the Lindero concessions 2.5 kilometers due south of the Lindero
project site remain open for evaluation. Exploration of these areas, as well as the Arizaro gold -
copper porphyry system, are priorities of the exploration program.
Fortuna is also revisiting the extensive reconnaissance exploration database comprising over
fifteen years of sampling and generative work in northern Argentina, acquired from Goldrock
Mines along with the Lindero P roject in 2016 . Evaluations of third -party properties are
ongoing.
Prospero Silver Corp. equity investment agreement, Mexico
Fortuna entered into an equity investment agreement with Prospero Silver Corp. (TSX-V: PSL) in
early 2017 (see Prospero Silver news release dated April 17, 2017 ). This alliance provides for
the initial drilling of multiple targets at Prospero’s Matorral, Petate, Pachuca SE and Bermudez
properties located in Durango, Hidalgo and Chihuahua States, respectively. High-level
epithermal clay alteration with anomalous gold, silver or pathfinder elements are present at
each property, none of which has been previously drilled.
The agreement gives Fortuna the right to select one of the projects to joint venture with
Prospero, potentially earning a 70% interest by spending US $8 million over six years and
completing a Preliminary Economic Analysis on the selected property. Should Fortuna exercise
its Prospero warrants, the right to select a second project under the same terms as above is
retained. The exploration strategy is to complete the planned drilling at all targets, assess the
data and select properties as dictated by the results.
Matorral Project
Three drill holes (1,371 meters) were completed on three different targets in August testing for
potential epithermal precious metal mineralization beneath extensive surface outcrops of
jasperoid. Sporadic anomalous silver from trace up to 32 ppm was intersected and the project
is on hold until completion of the entire drill program (see Prospero Silver news release dated
August 24, 2017).
Petate Project
Drilling was initiated on Sept ember 18, 2017 and the program calls for drilling 11 holes on four
separate targets. The project is the most advanced in the Prospero Silver portfolio with high-
level epithermal alteration exposed over a 5 kilometer by 4 kilometer area with highly
anomalous gold and silver mineralization hosted in extensive outcrops and float of strata-
-7-
bound jasperoid. Surface sampling by Prospero at the Apartadero target at Petate returned a
best continuous channel sam ple of 67.5m @ 0.93 g/t Au (see Prospero Silver news release
dated August 24, 2017).
Drilling at the Pachuca SE and Bermudez projects will follow in order after completion of the
drilling at Petate.
Prospero continues to evaluate new opportunities in Mexico, which will be made available for
consideration by Fortuna.
Medgold Resources Corp. equity investment agreement, Serbia
Fortuna entered into an equity investment agreement with Medgold Resources Corp. (TSX -V:
MED) in mid -2016 (see Medgold Resources news releases dated June 13, 2016 and June 21,
2016). The structure of the agreement gives Fortuna the right to select one of the projects
generated from a reconnaissance program to joint venture with Medgold. Fortuna has the right
to earn a 70% interest by spending US $8 million over six years and completing a Preliminary
Economic Analysis on the selected property. Fortuna exercised its Medgold warrants in early
2017, thus retaining the right to select a second project under the same terms as above , and
exercised its first property right by optioning the Tlamino project in southern Serbia (see
Medgold Resources news releases dated February 9, 2017 and March 7, 2017).
Tlamino Project, Barje Prospect
Preparations are underway to complete a 2,000 meter diamond drill program in spring 2018
following up on two campaigns of surface channel sampling on the Barje outcrop a nd an IP
geophysical survey. Results of the surface channel sampling over an area of approximately 30
meters by 100 meters of the Barje outcrop are:

The Barje prospect consists of ser icite schists overlying amphibolite gneisses separated by a
low-angle normal fau lt (detachment) that is presumed to be the locale of the mineralization
discovered to date.
Karamanica Prospect
Located approximately 8 kilometers west of the Barje Prospect , Karamanica hosts large -scale,
northwest-trending faults which cut packages of schists, calc -schists and quartz feldspar
porphyries. A mapping and rock -chip and soil sampling program completed over an area of
approximately 3 kilometers by 3 kilometers shows two gold-anomalous areas in soils measuring
1 kilometer by 1 kilometer and 600 meters by 800 meters with gold-in-soil values ranging up to
1 g/t Au and rock sample highs of 5.5 g/t, 7.1 g/t and 11.1 g/t (see Medgold Resources news
release dated October 2, 2017).
Additional work is planned for the 2018 field season.
Strategic Alliance Reconnaissance
Medgold Resources maintains a regional reconnaissance program that is identifying
opportunities for acquiring ground by staking new claims, all of which will be available for
evaluation by Fortuna.
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 Chemex Laboratory in Lima, Peru,
for samples from the Caylloma Mine , the ALS Chemex Laboratory in Guadalajara, Mexico , for
samples from the San Jose Mine or the ACME 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 ICP and atomic absorption
methods utilizing aqua regia digestion. The QA -QC program includes the blind insertion of
certified reference standards and assay blanks at a frequency of approximately 1 per 15 normal
samples as well as the inclusion of duplicate samples for verification of sampling and assay
precision levels.
