Silver Bull Files Maiden NI 43-101 Resource of 2.33 Million Ounces of Gold & 476 Thousand Tonnes of Copper in the “Indicated” Category, and 1.56 Million Ounces of Gold & 220 Thousand Tonnes of Copper in the “Inferred” Category on the Beskauga Copp

VANCOUVER, British Columbia, Feb. 16, 2021 (GLOBE NEWSWIRE) -- Silver Bull Resources, Inc. (OTCQB: SVBL, TSX: SVB) (“Silver Bull”) is pleased to announce it has filed the NI 43-101 Mineral Resource estimate report on the Beskauga copper-gold project completed by CSA Global Consultants Canada Ltd (“CSA Global”). The report is available on SEDAR at www.sedar.com and on the Company’s website at www.silverbullresources.com. Highlights of the Mineral Resource report include:

• An open pit-constrained Indicated Mineral Resource of 207 million tonnes grading 0.35 g/t gold, 0.23% copper and 1.09 g/t silver for 2.33 million ounces of gold, 476.1 thousand tonnes of copper, & 7.25 million ounces of silver.
  
• An open pit-constrained Inferred Mineral Resource of 147 million tonnes grading 0.33 g/t gold, 0.15% copper and 1.02 g/t silver for 1.56 million ounces of gold, 220.5 thousand tonnes of copper, & 4.82 million ounces of silver.
  
• The constraining pit was optimised and calculated using a NSR cut-off based on: $1,500/oz for gold, $2.80/lb for copper, $17.25/oz for silver, and with an average recovery of 81.7% for copper and 51.8% for both gold and silver.
  

Beskauga Resource: The Beskauga resource was estimated from 118 diamond drill holes, totalling 45,605.8 meters drilled between 2007 and 2017 by the private Swiss company, Copperbelt AG. Holes were drilled from surface using an HQ or NQ sized core diameter and varied in depth between 150m to 815m. The estimated Mineral Resource is shown in the table below.

Notes:

• An NSR $/t cut-off of $5.70/t was used, and the NSR formula is: NSR $/t = (38.137+11.612 x Cu%) x Cu% + (19.18 + 12.322 x Au g/t) x Au g/t + (0.07 + 0.0517 x Ag g/t) x Ag g/t
• The NSR formula incorporates variable recovery formulae. Average copper recovery was 81.7% copper and 51.8% for both gold and silver.
• Metal prices considered were $2.80/lb copper, $1,500/oz gold and $17.25/oz silver.
• The Resource is stated within a pit shell that considers a 1.25 factor above the metal prices.
• Mineral Resources are estimated and reported in accordance with the CIM Definition Standards for Mineral Resources and Mineral Reserves adopted 10 May 2014.
• The Mineral Resource is not believed to be materially affected by any known environmental, permitting, legal, title, taxation, socio-economic, marketing, political or other relevant factors
• These Mineral Resources are not Mineral Reserves as they do not have demonstrated economic viability.
• The quantity and grade of reported Inferred Resources in this MRE are uncertain in nature and there has been insufficient exploration to define these Inferred Resources as Indicated or Measured; however, it is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.

In order to address the potential for eventual economic extraction in an open pit context, the reported mineral resources fall within an optimized Lerch-Grossman pit shell that uses a gold price of US$1,500/oz, a copper price of US$2.80, and a silver price of US$17.25 with an average recovery of copper at 81.7% and gold and silver of 51.8%.

Pit walls are set at 42 degrees in the overburden and 45 degrees in the hard rock. Mining costs were assumed to be US$1.00 in overburden and US$1.50/tonne in the hard rock and processing costs were assumed to be US$5.70/tonne. To determine the $/t value of the rock the following calculation was made:

NSR $/t = (38.137+11.612 x Cu%) x Cu% + (19.18 + 12.322 x Au g/t) x Au g/t + (0.07 + 0.0517 x Ag g/t) x Ag p/t

Mineral resources were estimated by Ordinary Kriging using Micromine modeling software in multiple passes using 20 meter X 20 meter X 20 meter blocks as the SMU size. Blocks have been classified as Indicated or Inferred Mineral Resources.

The Mineral Resource was estimated by Serik Urbisinov, a Principal Resource Geologist for CSA Global, who is an independent Qualified Persons as defined by National Instrument 43-101. The full Technical Report is now available on the SEDAR website (www.sedar.com).

Infrastructure: The Beskauga deposit has excellent infrastructure. All operations are based out of the nearby mining town of Ekibastuz, which services the largest coal mine in Kazakhstan and provides a highly trained workforce for Silver Bull to draw upon. Paved road access, 1100 KVA power lines and heavy rail all lie within a 25 kilometer radius of the project. The capital city of Nur-Sultan, located approximately 300 kilometers along a double lane highway from the project, has a major international airport allowing for easy access and administration of the Beskauga project.

Tim Barry, President, CEO and director of Silver Bull states, “This is a great first step in development of the Beskauga project and wider regional potential. Kazakhstan is fast emerging as one of the premium mining jurisdictions on the planet. The prospectivity of the geology, coupled with the recently revised mining law and strong government support for the mining sector makes it a standout in the mining world. Furthermore, the outstanding infrastructure and access to the project adds significantly to Beskauga’s potential viability”.

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.
