SILVER BULL INTERSECTS 9 METERS OF SULPHIDE MINERALIZATION GRADING
20.7% ZINC, 1% LEAD AND 98G/T SILVER, INCLUDING 3.65 METERS OF MASSIVE
SULPHIDE MINERALIZATION GRADING 47.8% ZINC, 2.5% LEAD AND 105 G/T
SILVER 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 T17010 – 9 meters @ 20.7% zinc, 1.0% Lead, 98g/t silver and 0.26% copper
including 3.65 meters @ 47.8% zinc, 2.5% lead, 105g/t silver and 0.26% copper from
3.55 meters to 7.2 meters.
Hole T17009 – 3 meters @ 537g/t silver, 3.9% zinc and 1.06% copper including 1 meter
@ 1280g/t silver, 14.8% zinc and 2.3% copper from 0 meters to 1 meters.
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: Silver Bull is utilizing a company owned Termite drill rig 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 NQ diamond core and five drill
stations are presently planned with more expected to be added as the drill program progresses.

Tim Barry, President, CEO and director of Silver Bull states, “ We are extremely pleased with the
results from this batch of drill core . The new sulphide zone is proving to be very productive for
high grade sulphide mineralization. The drilling summarized in this news release targeted the
second of three steeply dipping, discreet structures we have identified in the sul phide zone.
Drilling from the first structure previously announced in the news releases of holes T17001 to
T17006 was dominated by high grade silver -copper sulphide mineralization grading up 1,300g/t
silver and 6% copper. Th is second stru cture is dominated by extremely high zinc sulphide
mineralization, grading up to 48% zinc and suggests a metal zonati on in the mineralization we
see at Sierra Mojada and provides very useful information in helping us vector into an intrusion,
interpreted as the source of metals currently defined on the project. In addition to vectoring in
on an intrusive source we can now project the mineralization we are currently drilling 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 three structures in this east-west trend similar in style, dip and grade of mineralization,
we see some very significant immediate targets 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 drill 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 T17007-T17010.
Figure 3. Location map of the channel samples in relation to the surveyed underground workings and mapped zones of mineralization. Also shown are the planned sites for
the drill program currently underway.
Figure 4.
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 pittable 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 compl iant 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 in dicated "high grade zinc zone" within the Lerchs -Grossman (LG)
Optimized Pit of 10.03 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 million 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 have been analyzed at ALS Chemex in North Vancouver,
BC, Canada. Samples are first tested with the "ME -ICP41m" procedure which analyzes for 35
elements using a near total aqua regia digestion. Samples with silver values above 100ppm are
re-analyzed using the Ag-GRA21 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 AA46
procedure which is a near total aqua regia digestion with an atomic absorption finish.
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 all sample
shipments to ensure integrity of the assay process.
About Silver Bull: Silver Bull is a mineral exploration company whose shares are listed on the
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.
