On 19^th June 2018, the Company announced an increase to its 2018 gold production guidance with stronger operating performance expected at Didipio and Haile. As a result, the Company's 2018 gold production guidance range was revised to 500,000 to 540,000 ounces.

On a consolidated basis, during the first half of 2018 the Company produced 268,597 ounces of gold, broadly in-line with the first half of 2017 as a full half of steady state operations at Haile offset lower production half-year production at Didipio. Second quarter gold production of 142,950 ounces was 14% higher compared to the first quarter of 2018 reflecting stronger production across all assets. Copper production for the second quarter was 3,919 tonnes and in-line with the previous quarter.

In the United States, Haile produced 75,693 ounces of gold, including 38,644 ounces of gold in the second quarter. The quarter-on-quarter increase in production is mainly attributable to improved plant availability and utilisation rates. Recoveries remained steady in the low 80% range and we continue to progress with the installation of the upgraded fine grind circuit to further improve recoveries, with commissioning expected in the first quarter of 2019.

In the Philippines, Didipio produced 58,797 ounces of gold and 7,808 tonnes of copper in the first half of 2018, including 33,140 ounces of gold and 3,919 tonnes of copper in the second quarter. The 30% quarter-on-quarter increase in production was a result of continued ramp-up of underground operations and the implementation of a revised mine plan.

In New Zealand, Waihi produced 39,320 ounces of gold, including 20,798 ounces of gold produced in the second quarter. The 12% quarter-on-quarter increase in production was a result of better equipment utilisation and higher mill throughput.

At Macraes, the operation produced 94,786 ounces of gold, including 50,368 ounces of gold produced in the second quarter. The 13% quarter-on-quarter increase in production was related to processing of higher grades and better recoveries.
