Ramp-up continues to advance at the high-grade gold Brucejack Mine, and the mine is targeting steady state production for the end of 2017. With the grade ramping up and the mill now exclusively processing stope ore, production of doré and flotation concentrate has increased. As a result of the increased production and the concomitant proceeds from the sale of doré and flotation concentrate, the Company is expected to achieve positive working capital by the end of this quarter. All of the main operating units in the mill building are performing as expected, and the plant is consistently operating at nameplate capacity of 2,700 tonnes per day or better. Optimization of the gold recovery process is ongoing and the start-up issues encountered within the gold room have been addressed. The production of metallic slag has been eliminated. Gold recovery at the shaker table has significantly improved, and overall, gold recoveries are currently exceeding 95%. Long-hole drilling is currently ...

Construction and mechanical commissioning at the mine has been substantially completed, and the demobilization of construction and contract crews, as well as construction facilities, is nearing completion. The permanent operations team has now assumed full management of the mine, and all of the main operating units in the mill are now fundamentally performing as expected. In May, ore was first introduced to the mill with a focus on ramping up tonnage throughput to nameplate capacity as quickly as possible with low-grade ore. During the month of June, the process plant at Brucejack processed 70,805 tonnes of ore (87.4% of one-twelfth of yearly nameplate capacity) from low-grade ore stockpiles for an average of 2,360 tonnes per day. Under the terms of the credit agreement among the Company and its lenders, the Commercial Production Date is defined as the first day of the calendar month immediately following the first calendar month during which the process plant processes ore at an ...

Highlights of the updated Mineral Reserve estimate include: Proven Mineral Reserves in the Valley of the Kings increased to 1.6 million ounces gold (3.3 million tonnes grading 14.5 grams per tonne gold) which is sufficient for the first three years of mine life. Proven and Probable Mineral Reserves in the Valley of the Kings increased to 8.1 million ounces gold (15.6 million tonnes grading 16.1 grams per tonne gold). Areas of gain in the Mineral Reserves are attributed to the following factors: Increasing drill density to 7.5-meter to 10-meter centers allowed for conversion of a significant amount of Probable Reserve to the Proven Reserve category. Mining stopes within the existing Mineral Reserve model along with expansion of the previous Indicated Mineral Resource wire frame accounted for an increase of approximately 620,000 ounces of gold. Several new, adjacent stopes were added to the previous mine plan as a result of the infill drilling reaching beyond the previously defined ore. ...

On February 17, 2016, we announced an updated cost estimate and project update for the Brucejack Project. Based on the achievement of the 60% engineering milestone, a capital cost estimate was carried out in late 2015 to update the June 2014 Feasibility Study cost estimate for the Brucejack Project. The estimated total project capital cost to complete design, construction, installation and commissioning, including contingencies and working capital, is US$696.8 million. Working capital for the three-month period of post-plant commissioning and initial gold production covers the cost of operations, but does not take into account any revenue generated during this period. The working capital estimate also covers the costs for prepayments related to electrical power and permitting, including US$9 million in government fees and bonds.
