Sabina Gold & Silver Announces Results From New Gold Trend Located 15 km North of the Goose Property, Back River Gold Project






Sabina Gold & Silver Corp (TSX:SBB), is pleased to report results from the 2018 summer exploration program from the Boulder property at its 100% owned Back River gold project in Nunavut Canada.


The Boulder property, one of five properties within the 80 kilometer iron formation gold trend at the Back River Project, is located approximately 15 km northwest of the Goose property, the current focus of Sabina’s development and exploration efforts (Figure 1a inset).


The geology at Boulder is similar to other prospective locations throughout the Back River District as it is host to extensive poly-deformed sequences of oxide iron formation, the principle host to gold mineralization at Back River.


Exploration at Boulder over the 2018 summer season focused on a >1.6 km trend of under explored, folded iron formation that has anomalous gold in till signatures. Sabina’s exploration approach, developed through a successful history of discovery at Goose, focuses on an optimal geologic framework that allows effective vectoring towards the definition of drilling targets. Using this approach exploration work at Boulder focused on prospecting, mapping, till sampling and a limited first pass drill program of four widely spaced, short drill holes totaling 1394 m.


Bruce McLeod, President and CEO, states, “As we continue with our significant success and discovery at the Goose project we are also developing and advancing targets throughout Back River district area. We have a robust district wide, target pipeline of over 50 quality showings and concepts. At Boulder, the Vega target offers considerable potential for discovery of a new shallow gold zone. Given its close proximity to Goose and the shallow nature of the iron formation sequence, any discovery here could have a positive impact on project economics and mine life. We look forward to future exploration at Boulder as we build on the excellent progress from our 2018 field work.”


Results of Field Work and Drilling


The Vega and Rainbow target areas at Boulder span >1.6 km of prospective iron formation that is modeled as a tightly folded syncline with appreciable thickness of iron formation. Historic drilling has occurred to the north in an area called the Humpback zone, where drilling returned best values of 18.32 g/t Au over 2.55 m, 6.7 g/t Au over 6.8 m, 9.56 g/t Au over 2.4 m. An additional two historic drill holes tested the southern end of the Vega target at an interpreted fold closure intersecting 50-70 meters of iron formation with minor veining and anomalous gold values of 3.4 g/t over 1.70 m. There is no historic drilling along the greater span of the target area.


During 2018, a 275 till sampling survey was conducted as an extension and infill program of a previous 2016 till survey. The detailed till sampling program involved collecting 3-4 kg of C-horizon till material on an offset grid with ~100 m line spacing and 50 m sample spacing. Samples were dried then analysed on site by field portable x-ray fluorescence for trace element analysis and subsequently sent for aqua regia digest. These surveys successfully highlighted anomalous gold in till down-ice of the known Humpback zone previously drilled in 2013 and a number of zones along the ~1.6 km length of untested iron formation that forms portions of the Rainbow and Vega target areas (Figure 1a). Interpreted up-ice sources of anomalous gold and arsenic in-till samples were used in conjunction with aeromagnetic and gravity geophysical surveys in planning of first pass drilling.


A total of four, shallow exploratory drill holes were drilled at the Vega (3 drill holes) and Rainbow (1 drill hole) targets (Figure 1b). At the Vega target a strong gold expression was returned from drill hole 18BRP046 that targeted an interpreted up-ice source of anomalous geochemical till samples in a shallow iron formation limb setting. Results of 2.41 g/t Au over 7.9 meters including 6.35 g/t Au over one meter were returned from a pyrrhotite and arsenopyrite bearing (locally up to 5%) quartz-flooded zone within chlorite altered oxide iron formation from 134.80 m 142.70 m.


These results are encouraging as they highlight a number of key elements proven necessary for vectoring of robust mineral zones at Goose; namely, a strongly anomalous gold signature associated with alteration and mineralization in a well-developed oxide iron formation stratigraphy.


Drill hole 18BRP049, targeted as a 200 m undercut to 18BRP046, similarly intersected ~100 meters of continuous oxide and silicate iron formation with zones of veining and quartz flooding associated with arsenopyrite and pyrrhotite mineralization and a limited anomalous gold signature with values up to 1.17g/t Au over 0.65m.


Drill hole 18BRP047 tested the magnetic anomaly, interpreted to be a tightly folded iron formation, ~450 m north of 18BRP046 and intersected two limbs of iron formation totalling ~60 m with anomalous gold intercepts of 1.63 g/t Au over one meter and 1.55 g/t Au over 1.37 meters.


At the Rainbow target, drill hole 18BRP048, targeted an anomalous break in the magnetic signature characteristic of iron formations at Back River, but failed to test the interpreted synclinal structure, and resulted in no significant mineralization or veining.


The 2018 drill and mapping support the interpretation that the magnetic anomaly at the Vega target is an isoclinal syncline extending several hundred meters vertically below surface. Sabina is encouraged by the geologic setting and the associated gold and alteration signatures of the Vega and Humpback target areas and believe that the area shows strong promise for discovery. A follow up program of drilling and field work is being planned for 2019.
