Silver Bull Intersects 10 Meters of Sulphide Mineralization Grading 347g/t Silver, 20.7% Zinc, 1.35% Lead & 1.25% Copper, on the Sierra Mojada Project, Coahuila, Mexico

VANCOUVER, British Columbia, March 14, 2018 (GLOBE NEWSWIRE) -- Silver Bull Resources, Inc. (SVB.TO) (SVBL) (“Silver Bull”) is pleased to provide results of the final three drill holes from the first zone of the 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 three holes announced in this news release include:

Hole T17023 – 10 meters @ 347g/t silver, 20.7% zinc, 1.25% copper, and 1.35% lead.
Hole T17024 – 3 meters @ 303g/t silver, 20.1% zinc, 1.53% copper, and 1.18% lead.
Hole T17025 – 1 meters @ 127g/t silver, 21.1% zinc, 0.29% copper, and 3.14% lead.

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.

Diamond core and five drill stations are presently planned with more expected to be added as the drill program progresses." data-reactid="18">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 meters 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 have identified two distinct zones of high grade sulphide mineralization that are 4 to 5 meters in width and trend in a roughly E-W direction. Our recent drilling has extended these two zones to over 150 meters each along strike. The zone to the north is dominated by high grade silver, up to 1,300g/t and high grade copper up to 3.3%, whilst the zone to the south has, in addition to high grade silver and copper, high grade zinc grading over 20%. This is interpreted to represent a zonation of metals in the deposit. In addition to the area recently 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 mineralization 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.

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 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.

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 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 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.

Forward-looking statements include, among others, statements regarding the planned drill program and the continuation of high grade mineralization to the west. These statements are based on current expectations, estimates, forecasts, and projections about Silver Bull's exploration projects, the industry in which Silver Bull operates and the beliefs and assumptions of Silver Bull's management. Words such as "expects," "anticipates," "targets," "goals," "projects," "intends," "plans," "believes," "seeks," "estimates," "continues," "may," variations of such words, and similar expressions and references to future periods, are intended to identify such forward-looking statements. Forward-looking statements are subject to a number of assumptions, risks and uncertainties, many of which are beyond our control, including such factors as the results of exploration activities and whether the results continue to support continued exploration activities, unexpected variations in ore grade, types and metallurgy, volatility and level of commodity prices, the availability of sufficient future financing, and other matters discussed under the caption "Risk Factors" in our Annual Report on Form 10-K for the fiscal year ended October 31, 2017, as amended, and our other periodic and current reports filed with the SEC and available on www.sec.gov and with the Canadian securities commissions available on www.sedar.com.
