Eastern Lateral Exploration and Infill Drilling Program
The 2016 drilling program successfully added two new inferred resource blocks in the eastern lateral extension, approximately 300 metres east of the Expansion Case PEA area, between the 340 and the 750 metre levels. The largest inferred resource block contains approximately 290,000 tonnes at a grade of 10.35 g/t of gold (approximately 95,000 ounces of gold). These two new blocks are relatively shallow and easily accessible from the existing mine infrastructure. As a result, the 2017 exploration program is following up on the eastern lateral extension area, particularly on a high-grade intersection (Hole GD-630-01) of 25.27 g/t gold over 3.85 metres located approximately 500 metres east of the new resource blocks that was identified in 2016, and continues to target the extension and infill of the new resource blocks.
Recent drilling in the eastern lateral extension has been focused in the down plunge extension of Hole GD-630-01. Highlights include:
- Hole GD-640-05 intersected 20.57 g/t (26.55 g/t uncut) of gold over a core length of 11.3 metres, at a vertical depth of approximately 1,000 metres;
- Hole GD-640-04, located approximately 150 metres above hole GD-640-05, intersected 7.38 g/t gold over 3.27 metres.
One directional drill rig has been redeployed to this area to follow-up on the exploration success in this area. The initial 2017 directional drill hole (GD-640-05-1) was completed between holes GD-640-04 and GD-640-05 noted above, and intersected two high-grade intervals at the same elevation, but located 40 to 50 metres north of GD-640-05. The first interval intersected 16.1 g/t gold (28.13 g/t uncut) over a core length of 8.33 metres and the second intersected 10.16 g/t gold (17.32 g/t uncut) over a core length of 5.74 metres. Additional drilling will be required to better understand the geometry and true width of this new area of high-grade mineralization. This new discovery represents significant upside to the potential extension of the eastern lateral corridor. A second directional drill rig will be added to accelerate drilling in this area.
Exploration and infill drilling has continued from the 340 metre level exploration drift that targets a potential extension and infill of the current resource blocks that were identified in 2016. One drill rig is working in the area and another drill rig will be added on the 620 metre level once the 300 metre extension of the exploration drift is completed in the second half of the year.
Recent highlights from Eastern Lateral exploration and infill drilling from the 340 metre level exploration drift (subsequent to the October 12, 2016 exploration press release), include (Table 2):
- Hole 340-576-02: 8.50 g/t gold over 2.00 metres;
- Hole 340-588-08: 14.96 g/t gold over 2.00 metres;
- Hole 340-588-11: 10.10 g/t gold over 3.00 metres;
- Hole 340-588-12: 10.24 g/t gold over 3.00 metres;
- Hole 340-588-13: 33.60 g/t gold over 2.00 metres;
- Hole 340-588-14: 10.60 g/t gold over 2.00 metres;
- Hole 340-588-15: 11.44 g/t gold over 4.36 metres.
A total of 8,232 metres (33 holes) of exploration and infill drilling of the planned 37,000 metres have been completed to date in the eastern lateral area.
