SABINA GOLD & SILVER DRILLS NEW HIGH-GRADE DISCOVERY AT BACK RIVER GOLD PROJECT AND INCREASES SUMMER DRILL PROGRAM TO 12,000M

Sabina Gold & Silver Corp. has provided the first results from the 2018 summer exploration diamond drilling program at its 100-per-cent-owned Back River gold project in Nunavut, Canada.

A significant new high-grade gold discovery, the Nuvuyak gold zone, occurring approximately one kilometre to the west of the Goose Main deposit, has been identified. Drill hole 18GSE545 targeted the high-priority Nuvuyak target and intersected 11.58 grams per tonne Au over 39.50 metres 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 chief executive officer. "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 metres 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 metres 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 kilometres 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 the company's 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 metres, which will include additional drilling on the Nuvuyak trend. Additional drill results will be released by the company as they are received and compiled.

About Sabina Gold & Silver Corp.

Sabina Gold & Silver is well financed with approximately $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-per-cent-owned Back River gold project which presents a project that has been designed on a fit-for-purpose basis, with the potential to produce about 200,000 ounces a year for about 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 Oct. 28, 2015). At a $1,150 (U.S.) gold price and a 0.80 (U.S. to Canadian dollar) exchange rate, the study delivers a potential after-tax internal rate of return of approximately 24.2 per cent with initial capital expenditures of $415-million.
