It’s been an exciting April so far: we’ve announced plans for an exploration program, we’re expecting our PFS for the Open Pit any day now and, of course, we continue to make excellent progress on the underground mine. Construction is progressing in a strong, steady fashion and we remain on track to enter production in Q4 of this year. Below is an update of recent activity on site.
East Main Shaft
We are making very good progress with lateral development on the 2850 and 2770 levels and have advanced over 650 feet on both levels since the last update. Importantly, we now have fully-mechanized mining on the 2850 level and are now just a few hundred feet from reaching the bottom of EN vent shaft
1000KV transformers have now been installed on both levels and we have completed construction of all sumps on the shaft bottom, 2770 level and 2850 levels. We also have a modified sump in place on the 2940 level.
In addition, we have developed several utility bays on the 2850 level, including the temporary shop.
Up next: complete excavation to the bottom of the EN vent shaft, begin ramping to the east ore bodies and begin mechanized mining on the 2770 level.

East-North Vent Shaft
Progress on the EN Vent Shaft has been particularly strong and we are now over 500 ft below surface.
Up next: continue sinking shaft and begin preparation to drive the Alimak from the 2850 level. The Alimak will be used to drive vertically up to intersect the East North Ventilation shaft and prepare the ore loading pocket.
The SAG mill pedestal is now complete and the Ball mill pedestal is almost finished. We have also finished pouring the Flotation foundation.
The foundations for the Thickener and fresh water areas have been completed and several pieces of critical components and equipment have arrived on site.
Dry stack tailings cell one is complete and is now in the process of being lined. The ore stockpile and surface water run off pond have been lined and completed.
Up next: Commence installation of equipment and start formwork for the ore stockpile loading hopper and for the filter press building
