Sabina Gold & Silver Drills New High-Grade Discovery at Back River Gold Project and Increases Summer Drill Program to 12,000m

Drill hole 18GSE545 returns 11.58 g/t over 39.50 meters confirming significant new discovery at the Nuvuyak Target
Drill Intercept located approximately 1 kilometer to the west of the Goose Main Deposit

VANCOUVER, Aug. 20, 2018 - Sabina Gold & Silver Corp (SBB.T) (“Sabina” or the “Company”) is pleased to announce first results from the 2018 summer exploration diamond drilling program at its 100% owned Back River gold project (“Back River” or the “Project”) in Nunavut, Canada.

A significant new high-grade gold discovery, the Nuvuyak gold zone, occurring approximately One kilometer to the west of the Goose Main Deposit, has been identified. Drill hole 18GSE545 targeted the high priority Nuvuyak target and intersected 11.58 g/t Au over 39.50 m with abundant visible gold. The mineralization at Nuvuyak is hosted in a strongly quartz veined, altered and mineralized iron formation sequence, and has a number of strong similarities to the high-grade Umwelt “Vault” zone. Successful drilling at Nuvuyak demonstrates the potential for further discoveries on this highly prospective district.

“Continued high-grade gold discoveries are an essential element in defining world class mineral districts.” stated Bruce McLeod, President and CEO. “We believe we can continue to grow our gold resources by aggressively exploring along both our better-known gold trends and the newly emerging gold trends that have been targeted for priority drilling. Nuvuyak may be the most significant discovery on the Property since the discovery of the Umwelt deposit. The discovery continues to highlight the strength of the gold system at Back River and the long-term value of the asset. Nuvuyak is an exceptional new discovery made by our in-house team that will continue to grow with the future of our company to the benefit of the shareholders.”

New Discovery

The Nuvuyak gold zone discovery intercept is located approximately 850 meters along strike to the west of the Goose Main deposit (Proven open pit Reserve of 3,266,000 tonnes grading 5.01 g/t totalling 526,000 ounces and an additional Probable open pit Reserve of 1,185,000 tonnes grading 4.98 g/t totalling 190,000 ounces) and approximately 1,000 meters down plunge. The mineralization is hosted within a polyphase folded sequence of the Back River lower iron formation stratigraphy and coincident gold structures that are interpreted as being a significant component of the major mineralizing horizon(s) at the Goose Property. Mineralization consists of arsenopyrite, pyrrhotite and greater than 50 occurrences of visible gold over broad intercepts that are associated with quartz veining and moderate to strong amphibole and chlorite alteration.

The mineralization horizon is also characterized as having many similarities with current Back River resources hosted at the Umwelt Vault zone greater than two kilometers along trend. Early interpretations recognize the potential for a large-scale mineral trend extending from Goose Main to Umwelt Vault that may transect large portions of the central Goose property, much of which is largely underexplored. The Nuvuyak gold zone remains open in all directions and will continue to be advanced by our exploration teams as programs allow.

Drilling is progressing very well with the objective of testing high impact targets at the Goose Property where summer drilling exploration has now been increased from 10,000 to 12,000 meters, which will include additional drilling on the Nuvuyak trend. Additional drill results will be released by the company as they are received and compiled.

Qualified Persons

The Qualified Person as defined by NI 43-101 as pertains to the Back River Project, is James Maxwell, P.Geo, Exploration Manager, for the Company. All drill core samples selected within the exploration program are subject to a company standard of internal quality control and quality assurance programs which include the insertion of certified reference materials, blank materials and duplicates analysis. All samples are sent to SGS Canada Inc. located in Burnaby, British Columbia where they are processed for gold analysis by 50 gram fire assay with finish by a combination of atomic absorption and gravimetric methods. Additionally, analysis by screen metallic processes is performed on select samples. SGS quality systems conform to requirements of ISO/IEC Standard 17025 guidelines and meets assay requirements outlined for NI 43-101.

Sabina Gold & Silver Corp.

Sabina Gold & Silver Corp. is well-financed with approximately C$62.4 million in cash and equivalents (Q2, 2018) and is an emerging precious metals company with district scale, advanced, high grade gold assets in one of the world’s newest, politically stable mining jurisdictions: Nunavut, Canada.

Sabina released a Feasibility Study on its 100% owned Back River Gold Project which presents a project that has been designed on a fit-for purpose basis, with the potential to produce ~200,000 ounces a year for ~11 years with a rapid payback of 2.9 years (see “Technical Report for the Initial Project Feasibility Study on the Back River Gold Property, Nunavut, Canada” dated October 28, 2015) (the “Study”). At a US$1,150 gold price and a 0.80 (US$:C$) exchange rate, the Study delivers a potential after tax internal rate of return of approximately 24.2% with an initial CAPEX of $415 million.

The Project received its final Project Certificate on December 19, 2017. The Project is now in the final regulatory and licensing phase.

In addition to Back River, Sabina also owns a significant silver royalty on Glencore’s Hackett River Project. The silver royalty on Hackett River’s silver production is comprised of 22.5% of the first 190 million ounces produced and 12.5% of all silver produced thereafter.
