Brucejack Drill and Exploration Programs

2021 Drill Programs include:

2021 Brucejack Mine Mineral Resource definition and expansion drill programs

The 2021 Brucejack Mineral Resource definition and expansion drill program adjacent to the underground mine infrastructure is anticipated to total approximately 195,000 meters of drilling comprised of in-reserve definition drilling (40%), in-resource and sustaining drilling (20%) and resource expansion drilling (40%). Underground resource expansion and exploration drilling will target near-mine zones with the potential to extend mineralization underground towards the West Zone, Galena Hill, Gossan Hill, and Bridge Zone. Initially, six drills are planned to be deployed underground, with an additional two surface drills to be added during the summer.

2020 Mineral Resource Expansion Underground Drill Program

2020 North Block Zone: Phase 1 Results

High-grade gold mineralization was identified in three new areas during Phase 1 drilling of the North Block Zone in 2020. Four intersections assayed above 1,000 grams per tonne gold.  Results include high-grade gold mineralization intercepts up to 300 meters from the current resource shell, including 19.3 grams per tonne gold over 9.0 meters in VU-2792 and 2,590 grams per tonne gold over 1.0 meter in VU-2794. 

The North Block Zone is located directly to the north of the Valley of the Kings deposit. The 2020 mineral resource expansion program was designed to test for Valley of the Kings style mineralization to the north and at depth. Phase 1 of the program was drilled from the 1050-meter level of the mine to target an area extending up to 300 meters north of the current resource shell. Phase 2 of the program was also drilled in 2020 to target an area up to 450 meters north of the current resource shell, and those drill results are pending.

Phase 1 of the North Block resource expansion program comprised 7,011 meters in 38 drill holes. Drilling identified three new zones: (1) an extension of the Domain 13 Stockwork, which is currently being mined in the Valley of the Kings, (2) a newly identified corridor of gold mineralization in the footwall of the Domain 13 structure, located 300 meters north of the current resource shell, and (3) a previously unidentified zone of gold mineralization located within 50 meters of existing development. See our news release dated February 25, 2021 for more information, including assay results.

2020 Mineral Resource Definition and Expansion Drill Program Overview

Diamond drilling activity continued to progress through the 2nd half of 2020 with up to five diamond drills on site conducting infill and resource drilling. Infill diamond drilling targeted Mineral Reserves proximal to mine infrastructure to build stope inventory and provide flexibility for near term mining. A total of 14,310 meters and 71,995 meters of infill diamond drilling were completed fourth quarter and full year 2020, respectively.

We expect to continue to focus on advancing underground development to expand mine access at depth and to the west. The increased development should provide sufficient access to build the stope inventory required to allow mining operations to optimize gold production and additional platforms for resource expansion drilling.

Resource expansion drilling continued through the fourth quarter 2020 with 22,730 meters completed within the North Zone to target previously intersected mineralization outside of the current Mineral Resource. A total of 27,780 meters has been completed since the program commenced in the third quarter of 2020.

The test reverse circulation (“RC”) drilling grade control program was introduced in staged phases, with the first drill in operation at the beginning of the second quarter on the 1080-meter level. A total of 22,317 meters and 75,953 meters of test RC drilling were completed in the fourth quarter and full year 2020, respectively. Two RC drills will continue to be used in combination with diamond drills to provide more comprehensive data to define stope shapes.
