SILVER BULL RESOURCES ANNOUNCES 5.35 BILLION POUNDS ZINC, 87.4 MILLION OUNCES

SILVER IN UPDATED SIERRA MOJADA MEASURED AND INDICATED RESOURCE:

INCLUDING SEPARATE AND DISTINCT HIGH-GRADE ZONES OF 13.5 MILLION TONNES AT 11.2%

ZINC AND 15.2 MILLION TONNES AT 114.9 G/T SILVER

Vancouver, British Columbia – Silver Bull Resources, Inc. (OTCQB: SVBL, TSX: SVB) (“Silver Bull”)

is pleased to provide an updated NI43 -101 Resource report for the Sierra Mojada Project in

Coahuila, Mexico. Highlights of the resource update include;

 An open pittable, measured and indicated “High Grade Zinc Zone” of 13.5 million tonnes

at an average grade of 11.2% Zinc at a 6% cutoff for 3.336 billion pounds of zinc.

 An open pittable , measured and indicated “High Grade Silver zone” of 15.2 million

tonnes at an average grade of 114.9 g/t at a 50g/t cutoff for 56.3 million ounces of silver.

 Total Measured & Indicated Global Resource 70.4 million tonnes at 38.6 g/t Ag and 3.4%

Zn that contain 5.354 billion pounds Zn and 87.4 million ounces Ag

 The updated resource was modelled using a silver price of US$15 per ounce, and a zinc

price of US$1.20 per pound.

“This resource update models the mineralization defined at Sierra Mojada to zinc and silver

prices realistic of the current market conditions ”, stated Tim Barry, President, CEO and

director of Silver Bull. “Sierra Mojada is one of only a handful of projects with any appreciable

zinc resources and is one of the largest undeveloped silver -zinc projects in Mexico. It has

excellent infrastructure; it is located 3 hours from an international airport with a paved road

right to site; it has a functioning railway right to site; runs on grid power; and it has a skilled

mining work force to draw upon in the immediate local area. This resource provides excellent

leverage to both zinc and silver prices and has the potential to be scaled in size depending on

metal prices.”

The Global Resource: The Global Resource is shown in table 1 with the “sub” tables defining the

High Grade Silver Zone and High Grade Zinc Zone using a silver and zinc cutoff grade a re shown

Notes

1) CIM definitions were followed for the Mineral Resource.

2) The Mineral Resource is reported within a conceptual pit-shell using an NSR cut-off value of US$13.50/tonne.

3) Mineral resources are not reserves and do not demonstrate economic viability.

4) Tonnages are reported to the nearest 100,000 tonne. Grade s are rounded to the nearest decimal place for Ag, Zn, & Pb and the

nearest 2 decimal places for Cu

5) Rounding as required by reporting guidelines may result in apparent summation differences between tonnes, grade, and containe d

metal.

6) Tonnage and grade are in metric units; contained Zn, Cu, & Pb are in imperial pounds.

7) Tonnages and grades are as reported directly from block model; with mined out areas removed.

Figure 2. Image showing the locations of the High Grade Silver Zone at a 50g/t Ag cutoff grade and Zinc Zone at a

6% Zn cutoff grade. The resource reported are the areas of these zones which fall within the optimized Whittle

Pit shown by the black outline.

In order to establish the economics in an open p it context, the reported resource s fall within a

Whittle Optimized pit shell that uses a silver price of US$15/oz and a zinc price of US$1.20/lb with

a recovery of silver estimated at 75% and zinc at 41%. Pit walls are set at 55 degrees overall,

mining costs were assumed to be US$1.50/tonne, and silver and zinc processing costs were

assumed to be US$12.00/tonne, which results in a total NSR cutoff for the resource of

$13.50/tonne.

Mineral resources were estimated by ordinary Kriging using GEMS TM modeling software in

multiple passes using 10 meter X 10 meter X 10 meter blocks as the SMU size. Blocks have been

classified as measured, indicated or inferred mineral resources.

The mineral resource has been estimated by Matthew Dumala , P.Eng., of Archer, Cathro &

Associates (1981) Limited and Timothy Barry, MAusIMM(CP)., of Silver Bull. Both Mr. Dumala and

Mr. Barry are Qualified Persons as defined by National Instrument 43 -101 and are responsible

for the Technical Report filed onto the SEDAR website “Technical Report on the Resources of the

Silver-Zinc Sierra Mojada Project Coahuila, Mexico”.

Changes in the resource: This new NI43-101 resource update supersedes the NI43-101 Resource

completed by S ilver Bull in June 2015. With significant movement in the metal prices of both

silver and zinc since 2015, management thought it prudent to recalibrate the mineral resource at

Sierra Mojada to the current price environment. This has resulted in an increase from US$1.00/lb

to $US1.20/lb for Zinc and a decrease from US$18/oz to US$15/oz for S ilver for this resource

update. This has resulted in a significant increase in the zinc resource and a slight decrease in the

silver resource at Sierra Mojada. A summary table between the two resources is shown below.

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

release uses the terms "measured resources", "indicated resources", 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, indicated 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 o f 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, esti mates of inferred mineral resources may not form

the basis of feasibility or other economic studies.

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.
