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 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 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 meters of NQ diamond core and five drill stations are presently planned with more expected to be added as the drill program progresses.
Assays for the holes reported are as follows:
|T17007||51.55||No significant results|
|T17008||72.5||No significant results|
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 sulphide 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. This second structure is dominated by extremely high zinc sulphide mineralization, grading up to 48% zinc and suggests a metal zonation 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 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 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.

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.
