In the second quarter of 2018, the Marigold mine produced 49,436 ounces of gold, a 15% increase

over the first quarter. Gold sales totaled 46,644 ounces for the quarter, reflecting an increase in

bullion inventory.

During the quarter, 16.0 million tonnes of material were mined, similar to the first quarter primarily

due to longer haul distances associated with the increase in ore tonnes. We expect total material

mined to increase during the second half of 2018 due to shorter haul distances and as the four

additional haul trucks enter service. These factors, along with completion of the new leach pad,

are expected to increase gold production through the second half of the year.

Approximately 7.9 million tonnes of ore were delivered to the heap leach pads, a quarterly record.

Gold grade increased to 0.42 g/t. This compares to 7.1 million tonnes of ore delivered to the heap

leach pads at a gold grade of 0.37 g/t in the first quarter of 2018. The strip ratio was 1.0:1 for the

quarter, 23% lower than the prior quarter.

(2) Beginning with the first quarter of 2018, the holder of a 3% net smelter returns royalty elected to receive its royalty in-kind

and we will no longer report these ounces within gold sold.

Seabee Gold Operation produced 23, 582 ounces of gold in the second quarter , in line with

production in the previous quarter . Gold sales were 20,500 ounces, lower than production as

gold ounces poured at the end of the second quarter will be sold in the third quarter.

The mill achieved an average throughput of 923 tonnes per day, an 11% decrease from the first

quarter. Production during the second quarter was impacted by planned maintenance, the

transition of mining activities to the high-grade Santoy mine, and a forest fire. Mill throughput is

expected to increase through the second half of the year relative to the second quarter . G old

recovery for the quarter remained consistent at 97.3%.

Notes:

(1) Figures are on 100% basis unless otherwise noted.

(2) Data for zinc production and sales relate only to zinc in zinc concentrate. “NA” indicates data not applicable due to

no comparable data available in Q1 2018.

(3) Figures are on a 75% attributable basis.

(4) Percent changes are calculated using rounded numbers presented in the table.

During the second quarter of 2018, the operation produced 1.0 million ounces of silver, for a total

of 1.9 million ounces produced in the first half of 2018, exceeding our silver production guidance

of 1.6 million ounces . Silver sales were 1.1 million ounces for the quarter, as concentrate

inventories were further reduced. Our attributable share of silver production and sales in the

second quarter were 0.7 million ounces and 0.9 million ounces, respectively.

Ore was milled at an average rate of 4,353 ton nes per day in the second quarter, 5% above the

previous quarter. Ore milled in the second quarter contained an average silver grade of 110 g/t,

4% lower than the 115 g/t average silver grade in the first quarter, consistent with processing of

increasingly lower grade stockpiles. The average silver recovery in the second quarter was 64%,

6% lower than the previous quarter.

We commenced production of zinc co ncentrate from stockpiles later in the second quarter, and

produced approximately 1.5 million pounds of zinc. No zinc sales occurred during the quarter.
