Sabina Gold & Silver Reports First Results from High-Grade Corridor Drilling at Umwelt Underground

 

 

 

 

 

Sabina Gold & Silver Corp (TSX-V:SBB) (OTCQX:SGSVF), is pleased to announce initial results from the summer drilling program at the Umwelt deposit on its 100%-owned Back River Gold Project in Nunavut, Canada.

 

Assays have been received for the first three of six drill holes completed at Umwelt following up on the strong results of higher grade drilling at the Vault Zone completed during 2017 to 2019 (see SBB NR 19-10 on June 18, 2019 for highlights from past Vault drilling).  The purpose of this year’s drilling is to test whether the higher than average grades encountered in the Vault Zone extend up plunge to the bottom of the planned open pit at Umwelt. If demonstrated, this could present an opportunity to revisit mine sequencing with a view to mining higher grade underground material earlier in the mine life.  This could have a dynamic impact on project economics, production profile and payback period. 

 

2020 drilling results in holes 20GSE571 to 20GSE573 strongly support the hypothesis of a second Vault type zone just below the bottom of the proposed open pit at Umwelt. Mineralized drill core from this current drilling is often striking, with coarse visible gold recognized in association with areas of elevated quartz veining, sulphide abundance and strong alteration. For example, a total of 30+ visible gold occurrences over 18 m were documented in drill hole 20GSE571 returning 15.15 g/t Au over 19.40 m.

“During the past three years we have demonstrated and considerably advanced the potential for higher grade zones within the current Umwelt underground reserve,” said Bruce McLeod, President & CEO.  “We are very encouraged by the strong start of this year’s program at Umwelt which has been focused on demonstrating a higher-grade corridor up plunge from the Vault Zone towards the bottom of the Umwelt open pit reserve.  The current underground reserve at Umwelt consists of three Cells, with the Vault Zone being partially included in Cell C at about 800 meters underground and still open down plunge.  These first three holes targeted drilling at Cell A and the top of Cell B and demonstrate the potential for an additional Vault type zone closer to the boundaries of the open pit.  This is important as it offers opportunities for higher grade material to be released earlier in the mine life and to significantly impact project economics. More drilling needs to be completed to better delineate these high-grades which are not currently incorporated in our reserve/resource estimate.  Our plans for 2020-21 include construction of an access ramp to provide a drill platform for further exploration drilling of these high priority targets.”

Umwelt Underground and High-Grade Corridor Drilling

 

Sabina’s focus on structural studies over the last three years has yielded strong exploration opportunities across the Goose Property and driven positive resource optimization and growth at Umwelt. As part of this focused approach, drilling in 2020 is committed to better define the continuity of higher than average grade potential within the Umwelt underground over approximately 815 m of plunge length that extends north from the Vault Zone towards the boundaries of the Umwelt Open Pit (Figure 1). Drill hole 20GSE571, collared the furthest up plunge from the Vault Zone, intersecting a well mineralized zone, 75 m down plunge of the planned open pit. Fifty-five meters down plunge, 20GSE573 interested a wide zone of mineralization returning 7.50 g/t Au over 24.75 m, with a high-grade core of 19.27 g/t Au over 7 m. Drill hole 20GSE572 is a larger step out, 255 m from 20GSE571, and 315 m up plunge from the successful 2019 Vault drill hole, 19GSE569. Drill hole 20GSE572 intersected 5.01 g/t Au over 27.45 m, including 12.64 g/t Au over 7.7 m, and marks the midpoint of the optimization drill targeting along the 600 m length of the Umwelt underground, supporting a strong continuance of the high grade corridor within the Umwelt underground.

 

Robust mineralization intersected by 20GSE571, 20GSE572 and 20GSE573 are associated with zones of coarse grained arsenopyrite, strong pyrrhotite mineralization and an increase in quartz veining. Drill holes 20GSE571 and 20GSE572 both intersect meter-scale quartz veining with semi-massive pyrrhotite, while the mineralization in 20GSE573 is associated with silicified iron formation, significant pyrrhotite mineralization and chloritic alteration. Visible gold was observed in all three holes.

 

The initial series of six drill holes is designed to delineate and detail the nature of a modelled secondary structure, which has never been discretely targeted. Upon receipt and evaluation of results drilling will continue this year at Umwelt with an additional three to five drill holes.

Update on Llama Extension Infill, Additional Exploration Targeting and Geophysics Programs

 

A secondary focus of the current summer drill program includes the completion of a series of infill and extension drill holes at the Llama Extension zone and the addition of several high priority exploration drill targets aimed at advanced discovery areas. In addition, Sabina has now recently completed a 2,064 line km VTEM survey over key areas of the Back River project for exploration advancement. Preliminary results of the survey are being reviewed for immediate follow up and continued data processing and integration continues.
