VANCOUVER, British Columbia, June 19, 2019 (GLOBE NEWSWIRE) -- Silver Bull Resources, Inc. (TSX: SVB, OTCQB: SVBL) (“Silver Bull”) is pleased to provide results from its first two drill holes on the Sierra Mojada Project in Coahuila, Northern Mexico.
Highlights from the first two holes announced in this news release include:
- Hole B19001 – 1.35 meters @ 10.47% zinc, 8.25% Lead and 586g/t silver and 1.8 meters @ 12.20% zinc, 1.4% lead, and 53g/t silver of mixed oxide/sulphide mineralization.
- Hole B19002 – 2.05 meters @ 7.81% zinc, 1.5% Lead and 36g/t silver of mixed oxide/sulphide mineralization
The Drill Program: Under a joint venture option agreement with South32, Silver Bull is conducting an initial 8,000 meter surface drill program targeting a series of possible sulphide extensions at depth to the main deposit, as well as a series of never before tested targets within the wider area.
For drilling, the company is using Major Drilling De Mexico S.A de C.V to initially target four historic mining areas within the property, three of which have never been drilled.
Results:
A summary of the results from the preliminary drilling east of the main deposit are shown in the table and map below.
| Hole ID | Hole Length (m) | From | To | Interval (m) | Ag G/T | Zn (%) | Pb (%) | Comments |
| B19001 | 380.7 | 318.2 | 320 | 1.8 | 53 | 12.2 | 1.4 | |
| 335.65 | 337 | 1.35 | 586 | 10.47 | 8.25 | high grade zone within a low grade halo of 13.35m @ 95g/t Ag, 1.3% Zn, 0.98% Pb |
| B19002 | 682.6 | 332.3 | 334.75 | 2.05 | 36 | 7.81 | 1.5 | high grade zone within a low grade halo of 40.45m @ 8g/t Ag, 0.93% Zn, 0.22% Pb |
| B19003 | 620.85 | Results Pending |

B19001 sits approximately 950 meters east of the defined deposit and shows mineralization continues along trend. Drill holes B19001 and B19002 sit along the very northern edge of the main deposit trend with the guts of the main trend lying further to the south.
Tim Barry, President, CEO and director of Silver Bull states, “The results from the first two holes in the East End are very encouraging. We have extended the mineralization an additional 950 meters to the east along strike of the Sierra Mojada Deposit, and show mineralization is far from drilled off in the area. Our interpretation of the results is that the drill holes clip the very northern edge of the main trend of Sierra Mojada deposit, and the guts of the system still lies to the south, untested. What is also encouraging is we are seeing a change from oxide mineralization to sulphide mineralization as we go deeper into the system. The advantage of sulphide mineralization over oxide mineralization, and why it is the target of this drill program is that it tends to be higher grade and will likely have a more standard metallurgical process to concentrate the ore. Since finishing up the B19003 drill hole in this area the drill has now moved off to the Palomas Negras prospect which sits 9 kilometers to the west of the main deposit. Results from the drilling at Palomas Negras are expected shortly.”
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.
South32 Joint Venture Option: In June 2018 Silver Bull signed an agreement with a wholly owned subsidiary of South32 whereby Silver Bull has granted South32 an option to form a 70/30 joint venture with respect to the Sierra Mojada Project. To maintain the option in good standing, South32 must contribute minimum exploration funding of US$10 million ("Initial Funding") during a 4 year option period with minimum aggregate exploration funding of US$3 million, US$6 million and US$8 million to be made by the end of years 1, 2 and 3 of the option period respectively. South32 may exercise its option to subscribe for 70% of the shares of Minera Metalin S.A. De C.V. ("Metalin"), the wholly owned subsidiary of Silver Bull which holds the claims in respect of the Sierra Mojada Project, by contributing US$100 million to Metalin for Project funding, less the amount of the Initial Funding contributed by South32 during the option period.
About Silver Bull: Silver Bull is a well-financed 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.
About the Sierra Mojada deposit: Sierra Mojada is an open pittable oxide deposit with a NI43-101 compliant measured and indicated "global" resource of 70.4 million tonnes grading 3.4% zinc and 38.6g/t silver at a $13.50 NSR cutoff giving 5.35 billion pounds of zinc and 87.4 million ounces of silver. Included within the "global" resource is a measured and indicated "high grade zinc zone" of 13.5 million tonnes with an average grade of 11.2% zinc at a 6% cutoff, giving 3.336 billion pounds of zinc, and a measured and indicated "high grade silver zone" of 15.2 million tonnes with an average grade of 114.9g/t silver at a 50g/t cutoff giving 56.3 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.
