Sabina Gold & Silver Corp (TSX:SBB) is pleased to announce final exploration results from 2018, including the down plunge expansion of the Nuvuyak discovery at Sabina’s 100% owned Back River gold project in Nunavut Canada.
In 2018, the Company completed 22,500 m of diamond drilling including 16,500 m of drilling during the summer exploration program. The summer program largely focussed on the new high-grade discovery at Nuvuyak as well as advancing additional high priority targets for the Goose Property which includes the Llama Extension (see press release Sept 18, 2018), Hook, Umwelt, and Echo zones.
Summer program results are highlighted by the rapid expansion of the Nuvuyak discovery where a strong down plunge extension of approximately 50 m is confirmed by new results (hole 18GSE559 returning 8.17 g/t over 13.00 m and drill hole wedge cut 18GSE559W1 returning 12.41 g/t over 8.70 m (see Table 1)).
Hole 18GSE559 intersected 50 m down plunge of the discovery hole 18GSE545. This hole, was used as a parent hole for a subsequent wedge cut (hole 18GSE559W1) which started at a depth of 435 m down hole 18GSE559. This hole also intersected mineralized iron formation 80 m up dip of the parent hole along the same section within a portion of the anticline hinge.
Sabina initially drill tested the Nuvuyak target in the spring of this year intersecting key exploration elements that led to the development of a geological vectoring model (see press release June 5, 2018). This model was tested in early summer drilling and resulted in the discovery of the Nuvuyak deposit (hole 18GSE545 returning 11.58 g/t over 39.50 m – see news release August 20, 2018). With the conclusion of the summer drill program, the Nuvuyak target has been tested over a total target length of approximately 200 meters along strike. The target remains open and untested in all directions with strong geologic control shown through current drilling intersections (see Figure 2, Nuvuyak – Hinge long section).
The Sabina geological team has hypothesized that an interconnected large-scale mineralization trend or a number of related trends exists at the Goose Property extending from the southern Goose Main zone to the northern Llama zone. The Nuvuyak discovery adds credence to this theory. Significant portions of the Goose Property are largely unexplored and Sabina plans to continue with targeting of these areas in future exploration programs.
Bruce McLeod, President and CEO stated “Sabina has successfully completed a number of de-risking activities during 2018 as we push towards project development while concurrently demonstrating, through exploration success that Back River is a world class gold project within an emerging district. Our success in making a new discovery at the Nuvuyak target, high grade optimization drilling at Umwelt Vault, confirming a sizable extension at Llama and demonstrating the Boulder property as an area for potential new discoveries, are significant developments in 2018. This work continues to unlock a much larger picture in terms of resource and district potential and overall mine life extension”.
During 2019, Sabina will follow up on the successful 2018 exploration programs. We are in the final stage of designing and budgeting a program of field mapping, rock sampling, till sampling, geophysics and diamond drilling at Back River. This work is designed to expand existing resources and advance and delineate exploration targets towards the discovery of new mineralization that has the potential to favorably impact project economics.
It is expected that a 6,000 m spring drilling program will commence in early March with an additional follow up program during the summer months. This year’s drilling will focus on following up on the significant 2018 results at Nuvuyak along with testing a number of targets that include the up plunge trending Hook zone and higher grade aras of the Llama extension structure.

Summer Drilling Summary
Sabina completed approximately 16,500 meters of drilling in 30 drill holes during the summer program with significant success at targets across the Back River Project. Drilling at the Goose Property in 2018 tested multiple high-priority exploration targets with the potential to extend the current mine plan or enhance project economics in and around the footprint of existing mineral resources. Results for the programs included significant success at the Llama Extension target (see news release September 18, 2018) as well as advancement in a number of key areas including Umwelt, Hook, Echo, and Nuvuyak West. Highlights of the exploration successes are summarized below. In addition, Sabina successfully demonstrated strong exploration targeting components at the Boulder Property located approximately 15km to the North of the Goose Property (see news release November 21, 2018). For a table of full 2018 results see table 2 within this release.
Hook Target and Nuvuyak Gold Structure Expansion
Additional 2018 drilling up plunge from the Nuvuyak target has intersected strong mineralization at an untested portion of an area known as the Hook target. This target area is a possible transitional gold zone that is aligned with the principle gold structure associated with both the Nuvuyak zone and the Goose Main deposit. Results from the Hook target in drill hole 18GSE558 (previously released) returned 9.48g/t over 9.10 m and 7.44g/t over 6.40 m. These results point towards potential for discovery of a shallower new mineral zone encompassing approximately 400-500 m of stratigraphy up plunge from the Nuvuyak target toward the current Goose Main resource.
Approximately 500 m west of the Nuvuyak target, two shallow drill holes were drilled to gather key stratigraphic positioning information and to trace the Nuvuyak – Goose Main gold structure. These drill holes successfully encountered many of the key exploration elements required for expanding the interpreted extents of this large-scale gold trend. Holes 18GSE560 and 18GSE561 both intersected a felsic dyke unit spatially associated with the known zones of mineralization at the Llama, Umwelt, and Goose Main deposits. The continuity of these felsic dykes and related structures through the
Goose Main, Hook and Nuvuyak areas indicate a potential for an emerging large-scale mineralization trend extending from the Goose Main deposit to west of the Nuvuyak zone. These two drill holes also successfully identified an antiformal younging reversal within the upper sediment lithologies that is interpreted to be coincident with the lower iron formation stratigraphic host antiform located vertically below.
Five of the six drill holes successfully targeted the Llama gold structure over a strike extent of approximately 200 m up-plunge from the previous 2017 and earlier 2018 drilling that returned a number of high grade intercepts over significant lengths (see previous news releases: Sept 5, 2017, April 2, 2018 & May 8, 2018). Selected significant values from these six drill holes included 17.96 g/t Au over 4.60 m from drill hole 18GSE548B and 6.20 g/t Au over 13.80 m from drill hole 18GSE547. A single drill hole, 18GSE546, drilled 26 m along strike in the open down-plunge direction from current drilling, returned values of 11.43 g/t Au over 5.48 m. Sabina has now shown that the extension of the Llama gold structure extends > 500 m below the current underground resources, remains open at depth and holds significant potential for resource expansion.
Drill hole 18GSE551 which returned 6.26 g/t Au over 9.25 m including 13.50 g/t Au over 3.00 m targeted extensional opportunities, in an area of possibly lesser grade up plunge and to the northwest of the Vault zone. The results of this drill hole are significant in that they highlight the potential for improvements in resource grade in certain areas outside of the Vault zone in the Umwelt underground.
Drill hole 18GSE543 tested the south west limit of the high-grade vault zone intersecting values of 4.51 g/t over 7.10 m.
Sabina will opportunistically continue to explore resource optimization opportunities at the Umwelt underground in future exploration programs.
