SILVER BULL INTERSECTS 16 METERS OF SULPHIDE MINERALIZATION GRADING
396G/T SILVER & 1.61% COPPER, INCLUDING 6 METERS GRADING 610G/T
SILVER & 1.12% COPPER ON THE SIERRA MOJADA PROJECT, COAHUILA, MEXICO
Vancouver, British Columbia – Silver Bull Resources, Inc. (TSX: SVB, OTCQB: SVBL) (“Silver Bull”)
is pleased to provide results from its continued underground drill program target ing the newly
discovered Sulphide Zone, which sits under the previously defined oxide zone on the Sierra
Mojada Project in Coahuila, Northern Mexico.
Highlights from the four holes announced in this news release include:
Hole T17003 – 16 meters @ 396g/t silver and 1.61% copper including 5 meters @
379g/t silver and 3.25% copper from 0 meters to 5 meters, and 6 meters @ 610g/t
silver and 1.12% copper from 10 meters to 16 meters.
Hole T17004 – 7 meters @ 370g/t silver and 0.85% copper. Hole hit historical workings
and was terminated
Hole T17006 – 4.8 meters @ 352g/t silver and 0.58% copper. Hole hit historical
workings and was terminated
The Sulphide Zone: A continuous underground channel sampling program conducted by Silver
Bull during the month of August 2017 identified a series of east-west trending high angle
structure hosting sulphide mineralization (announced in a news release on 11 September 2017).
Results from the continuous channel sampling program yielded 31.5 meters grading at 22.36%
zinc, 134.5g/t silver, 2.05% lead, 0.21% copper and 10.5 meters @ 432g/t silver, 1.15% zinc,
0.05% lead, 1.22% copper and is the target of the current drill program
The Drill Program: For the drill program Silver Bull is utilizing a company owned Termite drill rig
which aims to test the grade, thickness, and continuity of the sulphide mineralization identified
by the channel sampling program. The Termite is capable of drilling up to 100 mete rs of N Q
diamond core and five drill stations are presently planned with more expected to be added as
the drill program progresses.
Assays for the holes are as follows:
Hole_ID Hole Length (m) From (m) To (m) Interval (m) Ag (G/T) Cu (%)
T17003 60.65 0 16 16 396 1.61

T17005 31 No significant results
T17006 7.5 0 4.8 4.8 352 0.58
Tim Barry, President, CEO and director of Silver Bull states, “The results from this batch of drilling
in the sulphide zone are exceptional. The consistent high grade silver -copper mineralization we
see in this particular area is hosted along a steeply dipping fault and remains open down dip and
in the east and west directions. From what we now know, it has also become apparent that this
zone is severely underrepresented in historic drilling as the historic surface drill holes in this area
are vertical, meaning that unless they were drilled directly down the steeply dipping structures
we are currently defining, any drilling in this area would have completely missed these very high
grade zones. As we understand more about this area we can now project the mineralization into
the extensive channel sampling and drilling completed at the eastern end of the deposit and
show a target over 3 kilometers in strike length. When you consider this, coupled with the fact
we have identified at least two other structures s imilar in grade of mineralization, dip and
orientation, it presents a very significant target and only adds to the sulphide story at Sierra
Mojada. In addition to the drilling, work is currently underway to access some of the underground
workings further east to confirm the style of mineralization.”
A summary of the results are shown in the maps below.
Figure 1. Location of the new sulphide zone of mineralization in relation to the previously defined oxide 43-101 resource previously defined at Sierra Mojada. This new zone
will be the initial target of the planned drill program.
Figure 2. Summary of the drill holes drilled to date. This news release focuses on drill holes T17003-T17006.
Figure 3. Plan view of the drill holes drilled from the first underground drill station. The drilling is very clearly defining a high grade silver-copper zone that is open to the NW
and SE and down dip (see cross section of this zone in Figure 4).
Figure 4. Cross section through drill holes T17001-T17006. Very clearly the high grade silver-copper mineralization can be
seen sitting underneath the NI43-101 compliant oxide resource (shown in blue) and appears to feed up into the oxide zone.
Mineralization remains open along strike and down dip.
Figure 5. Shown in the image above are locations of historical channel samples grading >0.5% copper and 100g/t silver in relation to the sulphide zone currently being drilled.
The sulphide zone sits along strike and is interpreted as the extension of a zone defined by historical underground channel samples. This defines a target over 3 kilometers in
strike which is open in the east and west directions. Work is currently underway to access some of the underground workings in these areas to confirm the style and tenor of
the projected extension of mineralization.
About the Sierra Mojada deposit : Sierra Mojada is an open p ittable oxide deposit, as disclosed
in the NI43 -101 "Technical Report on the Resources of the Sierra Mojada Project Coahuila,
Mexico" dated June 8, 2015, with a NI43 -101 compliant measured and indicated "global"
resource of 58.7 million tonnes grading 3.6% zinc and 50g/t silver at a $13.50 NSR cutoff giving
4.670 billion pounds of zinc and 90.8 million ounces of silver. Included within the "global"
resource is a measured and indicated "high grade zinc zone" within the Lerchs -Grossman (LG)
Optimized Pit of 1 0.03 million tonnes with an average grade of 11% zinc at a 6% cutoff, giving
2.426 billion pounds of zinc, and a measured and indicated "high grade silver zone" of 19 million
tonnes with an average grade of 102.5g/t silver at a 50g/t cutoff giving 62.6 mil lion ounces of
silver. Mineralization remains open in the east, west, and northerly directions. Approximately
60% of the current 3.2 kilometer mineralized body is at or near surface before dipping at around
6 degrees to the east.
Sample Analysis and QA/QC: All samples will be analyzed at Bureau Veritas in Vancouver, BC,
Canada. Samples will be first tested with the "MA300" procedure which analyzes for 36
elements using a 4 acid digestion. Samples with silver values above 100ppm are re-analyzed
using the FA350 procedure which is a fire assay with a gravimetric finish. Samples with zinc,
lead, and copper values above 10,000ppm (1%) are re-analyzed using the AR402 procedure
which is a near total aqua regia digestion.
A rigorous procedure is in place regarding sample collection, chain of custody and data entry.
Certified standards and blanks, as well as duplicate samples are routinely inserted into sample
shipments to ensure integrity of the assay process.

Toronto Stock Exchange and trade on the OTCQB in the United States, and is based out of
Vancouver, Canada. The "Sierra Mojada" project is located 150 kilometers north of the city of
Torreon in Coahuila, Mexico, and is highly prospective for silver and zinc.
