SILVER BULL INTERSECTS 6 METERS OF SULPHIDE MINERALIZATION GRADING

802G/T SILVER, 5.87% ZINC, & 3.3% 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 of 7 drill holes from its continued underground drill program

targeting 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 seven holes announced in this news release include:

 Hole T17022 – 6 meters @ 802g/t silver, 5.87% zinc, 3.3% copper, and 0.54% lead.

 Hole T17019 – 2 meters @ 1,300g/t silver, 13.52% zinc, 3.87% copper, and 2.95% lead.

 Hole T17021 – 6 meters @ 5.8% zinc, and 0.47% copper.

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, and 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.

Tim Barry, President, CEO and d irector of Silver Bull states, “We are extremely pleased with the

results from this batch of drilling. 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 sulphide zone. Drilling from

the first structure announced in the previous news releases of holes T17001 to T17014 were

dominated by high grade silver-copper sulphide mineralization grading up 1,300g/t silver and 6%

copper. A second structure defined by holes T17010 and T17018 to T17022 is dominated by

extremely high zinc sulphide mineralization, grading up to 48% zinc and suggests a metal zonation

in the mineralization. In addition to the area currently being drilled we have opened up an

additional 350 meters of historical workings along the east -west trend of the sulphide

mineralization which was announced in January 2018. This channel sampling program clearly

shows the continuation of high grade mineralizatio n towards the west. Our underground

geological mapping of this area shows a number of high angle structures up to 2 meters wide

containing sulphide mineralization grading up to 1,300 grams per ton silver, 42% zinc, 18% lead,

and 13% copper that appear to feed into the overlying oxide zone. This will be the next target of

our drill program in this area”.

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 announced to date. This news release focuses on drill holes T17016-T17022. A selection of holes previously announced is also shown for

reference.

Figure 3. Cross section through drill holes T17010 and T17019-T17022. Very clearly the high grade zinc-silver-copper sulphide

mineralization which can be seen sitting underneath the NI43-101 compliant oxide resource (shown in blue) and which

appears to feed up into the oxide zone. Mineralization remains open along strike and down dip.

Figure 4. Location of the new sulphide zone identified through the reconditioning of 350 meters of new underground workings (announced on 10 January 2018) in relation to

the area of sulphide mineralization drilled in 2017 and hole B11144, which intersected 8.45 meters @ 17% Zinc, 5.45% lead, and 60g/t silver. All known sulphide occurrences

are located in an east-west trending chargeability high identified in an Induced Polarization geophysics survey. This geophysics anomaly is over 1.4 kilometers in length and is

open to the west. These new areas will be the target of the next phase of underground drilling in this area..

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 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 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 cut off 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 abov e 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.

Cautionary Note to U.S. Investors concerning estimates of Measured, Indicated, and Inferred Resources: This

press release uses the terms "measured resources", "indicated resourc es", and "inferred resources" which are

defined in, and required to be disclosed by, NI 43-101. We advise U.S. investors that these terms are not recognized

by the United States Securities and Exchange Commission (the "SEC"). The estimation of measured, in dicated and

inferred resources involves greater uncertainty as to their existence and economic feasibility than the estimation of

proven and probable reserves. U.S. investors are cautioned not to assume that measured and indicated mineral

resources will be converted into reserves. The estimation of inferred resources involves far greater uncertainty as to

their existence and economic viability than the estimation of other categories of resources. U.S. investors are

cautioned not to assume that estimates of inferred mineral resources exist, are economically minable, or will be

upgraded into measured or indicated mineral resources. Under Canadian securities laws, estimates of inferred

mineral resources may not form the basis of feasibility or other economic st udies.

Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian regulations, however the SEC

normally only permits issuers to report mineralization that does not constitute "reserves" by SEC standards as in

place tonnage and grade without reference to unit measures. Accordingly, the information contained in this press

release may not be comparable to similar information made public by U.S. companies that are not subject NI 43 -

101.
