Sabina drills 22.75 m of 23.52 g/t Au at Back River

2020-10-13 07:56 ET - News Release

Mr. Bruce McLeod reports

SABINA GOLD & SILVER REPORTS MULTIPLE HIGH-GRADE INTERCEPTS FROM UPPER PORTION OF UMWELT HIGH-GRADE CORRIDOR (V2 ZONE)

Sabina Gold & Silver Corp. has provided further high-grade assay results from drilling of the upper portions of the high-grade corridor at the Umwelt underground resource (the V2 zone) on its 100-per-cent-owned Back River gold project in Nunavut, Canada.

Internal studies conducted earlier this year suggest that mining higher grade underground material at the beginning of the mine life could have a significant positive impact on project economics by increasing gold production in the early years. Drilling was designed to delineate and detail the nature of the high-grade structure at Umwelt, which has never been discretely targeted. During the 2020 field program, nine holes were drilled, proving the hypothesis that additional high-grade corridors exist between the Vault zone at depth and the bottom of the proposed open pit at Umwelt.

This year's drilling focused on a zone directly under the proposed Umwelt open pit (V2 zone) at a depth that ranges from 135 m to 285 m below surface, over a plunge extent of approximately 300 m. All seven drill holes targeting this zone returned exceptional widths of gold mineralization, up to two to three times the average grade of the Umwelt underground reserve. The V2 zone is very similar to the Vault zone, further supporting the concept of additional high-grade underground corridors within the Umwelt deposit. These results will be incorporated into an updated feasibility study expected to be released in the first quarter of 2021.

To further explore the high-grade corridor at Umwelt, the company is moving forward with an underground exploration ramp that can facilitate further exploration drilling as well as provide for bulk sampling. The exploration ramp could provide early access to continue exploring the V2 zone with approximately 1,500 m of ramp development. The initial surface work and mobilization of equipment required to support the exploration ramp are under way, with collaring of the decline expected in early 2021.

These assay results are the final three holes from the V2 zone and include:

  • Hole 20GSE581, which returned 16.59 grams per tonne over 20.55 metres;
  • Hole 20GSE582, which returned 14.78 g/t over 22.75 m;
  • Hole 20GSE584 which returned 14.78 g/t over 24.80 m.

One additional drill hole 20GSE576 targeted mineralization located 200 m below the V2 zone with results as described in the "Significant intercepts from select drill holes since Sept. 3" table.

Highlights from previous drilling at V2 as reported includes 15.15 g/t over 19.40 m in hole 20GSE571 (see news release dated Aug. 20, 2020) and 19.89 g/t over 32.20 m in drill hole 20GSE575C (see news release Sept. 3, 2020). See the "Summary of 2020 main significant intercepts through the V2 zone" table.

"The consistent widths and high grades returned to date from our V2 zone highlight and confirm upside to the Umwelt underground resource," said Bruce McLeod, president and chief executive officer. "This could enable an optimization to our mine sequencing, enhancing the economics of an already robust project as well as provide the opportunity to increase the production profile in the early years of the mine life. The company intends to incorporate these results into an updated feasibility study to be completed in Q1 2021. Currently Sabina has commenced civil works to prepare for collaring of the exploration ramp next spring for the purpose of accelerating additional underground drilling to further define opportunities at the Umwelt underground."

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 was 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 toward the boundaries of the Umwelt open pit.

Mineralization intersected by drill holes 20GSE581, 20GSE582 and 20GSE584 continues to demonstrate the exceptional tenor of mineralization associated with the Umwelt gold structures and is an excellent example of many of the best features characterizing Back River gold zones. Iron formation consists of moderate to strong chlorite, actinolite and silica alteration with pervasive quartz veining hosting common sulphides including pyrrhotite and arsenopyrite occurring heavily throughout the zone. These three drill holes are excellent examples of the robust mineralization style that includes heavy sulphidation of the host rock with exceptional grade occurring proximal to the lower contact of the iron formation units. Rheologic contrast of the stratigraphy and high-iron content of the host horizon are interpreted as favourable features in establishing high-quality deposits at Back River. Visible gold was observed in all holes targeting the Umwelt underground V2 zone reported to date.

Drilling has now completed with two phases at Umwelt through nine holes supporting the objective.

Update on additional exploration targeting and geophysics programs

Upon receipt of the final versatile time domain electromagnetic (VTEM) data collected at the Goose property and other regional areas as part of this year's field program, Sabina will undertake additional forward modelling and rigorous data review in preparation for additional exploration drilling in 2021. With the help of experts, this new data set will be studied at known deposits to properly characterize physical properties of mineralization and key structures. This characterization will then play an important role in target prioritization and evaluation of regional areas.

Exploration drilling has also been completed at several high-priority targets, however, results are pending at this time.

About Sabina Gold & Silver Corp.

Sabina Gold & Silver is well financed 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).

The project received its final project certificate on Dec. 19, 2017. The project received its Type A water licence on Nov. 14, 2018, and its listing to enable deposition of tailings on Schedule 2 of the Metals and Diamond Mining Effluent Regulations on June 25, 2020. The company is now in receipt of all major authorizations for construction and operations.

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 comprises 22.5 per cent of the first 190 million ounces produced and 12.5 per cent of all silver produced thereafter.
