Silver Bull Announces Termination of Option Agreement With South32 at Sierra Mojada

VANCOUVER, British Columbia, Sept. 01, 2022 (GLOBE NEWSWIRE) -- Silver Bull Resources, Inc. (OTCQB: SVBL, TSX: SVB) (“Silver Bull”) announces the termination of the option agreement with a wholly-owned subsidiary of South32 Limited (“South32”) at the Sierra Mojada project located in Coahuila, Mexico. The Sierra Mojada project has been illegally blockaded (see news release from September 30, 2019) and thus there has been an inability to progress investment in exploration activities.

Tim Barry, CEO commented, “While we are disappointed that South32 has decided to terminate the option agreement for Sierra Mojada, we understand their reasoning given the inability to access the project site since September 2019. We appreciate South32’s professionalism throughout this partnership.”

Mr. Barry went on to say, “The ongoing illegal blockade of the Sierra Mojada project by the local mining cooperative, Sociedad Cooperativa de Exploración Minera Minero Norteños S.C.L., has been in place since September 2019. There has been no intervention by the appropriate authorities to bring this to an end and despite the Company’s many attempts to reach a reasonable path towards an amicable settlement, we have been unable to gain permanent access to the project site. We hope that this unfortunate recent outcome will encourage the appropriate government agencies to take immediate action to remove the illegal blockade for the betterment of the project and the broader local community and businesses.”

Silver Bull will continue to assess the current situation at Sierra Mojada and other opportunities outside of Mexico as they present.

About Silver Bull Resources:

Silver Bull’s primary asset is the Sierra Mojada deposit located in Coahuila, Mexico. Sierra Mojada is an open pittable oxide deposit with a NI 43-101 compliant Measured and Indicated “global” Mineral Resource of 70.4 million tonnes grading 3.4% zinc and 38.6 g/t silver for 5.35 billion pounds of contained zinc and 87.4 million ounces of contained silver. Included within the “global” Mineral 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, for 3.336 billion pounds of contained zinc, and a Measured and Indicated “high grade silver zone” of 15.2 million tonnes with an average grade of 114.9 g/t silver at a 50 g/t cutoff for 56.3 million contained ounces of silver. Mineralization remains open in the east, west, and northerly directions.

The constraining pit was optimised and calculated using a NSR cut-off based on a silver price of US$15/oz, and a zinc price of US$1.20/lb and assumed a recovery for silver of 75% and a recovery for zinc of 41%. Approximately 60% of the current 3.2-kilometer mineralized body is at or near surface before dipping at around 6 degrees to the east.

Cautionary Note to U.S. Investors concerning estimates of Measured, Indicated, and Inferred Mineral Resources: In October 2018, the U.S. Securities and Exchange Commission (the “SEC”) approved final rules requiring comprehensive and detailed disclosure requirements for issuers with material mining operations. The provisions in Industry Guide 7 and Item 102 of Regulation S-K have been replaced with a new subpart 1300 of Regulation S-K (“S-K 1300”) under the Securities Act of 1933 (the “Securities Act”). The Company will be required to comply with these new rules in its disclosures for the fiscal year ending October 31, 2022, and thereafter. The requirements and standards under S-K 1300 differ from those under Canadian securities laws. This news release uses the terms “measured mineral resources”, “indicated mineral resources”, and “inferred resources” which are defined in, and required to be disclosed by, NI 43-101 under guidelines set out in the Definition Standards for Mineral Resources and Mineral Reserves adopted by the Canadian Institute of Mining, Metallurgy and Petroleum Council. While the terms are substantially similar to the same terms defined under S-K 1300, there are differences in the definitions. Accordingly, there is no assurance any mineral resources or mineral reserves that the Company may report under NI 43-101 will be the same as resource or reserve estimates prepared under the standards adopted under S-K 1300. The estimation of measured, indicated and inferred mineral 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 mineral resources involves far greater uncertainty as to their existence and economic viability than the estimation of other categories of mineral 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 news release may not be comparable to similar information made public by U.S. companies that are not subject NI 43-101.
