• Full year 2021 guidance reaffirmed.

Michael Holmes, President and CEO of OceanaGold said, "First quarter 2021 results demonstrate our determination to deliver on our commitments. Despite one-off milling challenges at Haile and Macraes, the ingenuity of our teams ensured we delivered on first quarter expectations, and we remain on-track to achieve full year 2021 guidance. At Haile, the operation delivered record total mining movements during the first quarter and quickly identified, evaluated, and resolved disruptions to milling. At Macraes, despite failure of one of our mill motors that slowed throughputs, the operation produced just under 35,000 gold ounces during the quarter, and full year guidance remains unchanged."

"We continue to advance our organic growth pipeline of three new underground mines over the next two years in favourable jurisdictions. In New Zealand, Martha Underground is on-track to begin continuous production late in the second quarter and underpins the greater Waihi District. We plan on drilling at Waihi for years to come and adding to the already robust mine life. At Macraes, main access and ventilation declines for the Golden Point Underground are underway, and the project is on-track for first production by year-end. Haile Underground preparation continues in anticipation for portal development later this year."

"We remain in dialogue with appropriate representatives at national and local levels on Didipio's FTAA renewal status. Currently the renewal is with the Department of Environment and Natural Resources for re-endorsement to the Office of the President. In the meantime, we are maintaining Didipio in a state of operational stand-by and planning for the transition to full production. COVID-19 risks remain elevated in the Philippines and at site where nine members of our workforce have tested positive for the virus over the last year. Ongoing risks associated with the pandemic could impact the timeline associated with returning to full operations."

"OceanaGold is a resilient and dynamic gold miner with a strong and sustainable future. We are excited about the next few years and the opportunity we have to drive value from internal growth. Our relentless focus on delivering on our commitments, restarting Didipio and advancing organic growth is expected to create value for shareholders over the long-term."

Operations

For the quarter ended March 31, 2021, the Company produced 83,191 ounces of gold, reflecting a 3% increase over the previous March quarter and 16% decrease quarter-on-quarter. Increased production relative to the first quarter of 2020 reflects stronger performance from Haile partly offset by lower production from the New Zealand operations. Decreased production quarter-on-quarter is primarily attributable to New Zealand where a milling disruption impacted Macraes, and Waihi ran a reduced processing campaign as planned. Haile was also lower with a higher average feed grade offset by lower mill throughput. Didipio remained in a state of operational standby.

Increasing consolidated cash costs of $800 per ounce and All-in Sustaining Costs ("AISC") of $1,229 per ounce sold reflected the lower production and higher capitalised pre-stripping quarter-on-quarter, particularly at Macraes. The Company recorded gold sales of 82,847 ounces in the first quarter, a 14% decrease from the fourth quarter of 2020.

At Haile, the operation produced 44,341 gold ounces in the first quarter, up 51% from the previous March quarter on improved mining productivity. First quarter gold production and mill throughput were 10% and 20% lower respectively quarter-on-quarter, due to challenges with the flow of saturated saprolitic ore to the plant (which were addressed and rectified during the quarter) and a planned three-day plant shutdown. Concurrently, total mining movements increased 24% and 7% over the prior March quarter and fourth quarter 2020 respectively, and the operation achieved record total movements in the quarter.

Unit mining and milling cost increases at Haile during the first quarter reflect lower plant throughput, the impact of one-off costs related to mitigating plant disruption from saturated ore, and to a lesser extent, additional headcount to address COVID-19-related workforce absenteeism. Confirmed COVID-19 cases at site increased from 63 at the end of 2020 to 111 during the first quarter. The Company continues to expect Haile to produce 150,000 to 170,0000 gold ounces at a site AISC of $950 to $1,100 per ounce sold and notes that the outlook could be adversely impacted by additional challenges related to the COVID-19 pandemic.

In New Zealand, Waihi produced 4,337 gold ounces in the first quarter. Activities at Waihi primarily focussed on the development of Martha Underground, including the completion of 2,311metres of underground development during the first quarter. In addition, the Company declared the first Reserve of 620,000 gold ounces at Martha Underground ("MUG") in conjunction with the completed feasibility-level study. Development of MUG is on-track for continuous production to begin in June following the replacement of Waihi's existing SAG mill. Full year 2021 guidance at Waihi remains unchanged.

Macraes production decreased 19% quarter-on-quarter and 12% over the prior March quarter primarily as a result of a one-off disruption to milling operations from a mill motor outage in early February. In addition, exceptionally high rainfall in January required evacuation of Frasers Underground for two weeks and temporarily prevented access to ore mining in open pits; as such, mining efforts were directed to increased waste mining and pre-stripping at Deepdell North open pit. Higher first quarter AISC reflects the lower mill throughputs and increased sustaining capital investments and pre-stripping activities. Full year guidance for Macraes remains unchanged. The Company expects to replace the mill motor in the second quarter concurrent to the scheduled rebricking of the autoclave.

Didipio remains in a state of operational standby, and there was no production in the first quarter due to the suspension of operations due to the ongoing blockade of the access road. The Company expensed $4.5 million of holding costs as part of consolidated Corporate General and Administration, which related to maintaining Didipio in a state of operational standby. This compares to $9.1 million in the prior quarter. The Financial or Technical Assistance Agreement ("FTAA") is currently pending re-endorsement from the Philippine Department of Environment and Natural Resources ("DENR") to the Office of the President. The Company is unable to provide a specific timeline to complete the renewal. The spread and effective management of COVID-19 in the Philippines may be a factor in the timeline for resumption of normal operations, which could take up to 12 months. Since March 2020, nine positive COVID-19 cases have been managed at Didipio, four of which occurred in the first quarter of 2021.

Financial

In the three months ended March 31, 2021, the Company generated $148.9 million in revenue and adjusted EBITDA of $66.5 million, 11% and 6% lower than the previous quarter, respectively, due to lower gold sales from New Zealand. First quarter revenue and adjusted EBITDA increased 8% and 34% above the prior March quarter, respectively, due to improved performance from Haile and an 18% higher average gold price received during the period.

Adjusted net profit (excluding Didipio carrying costs) was $21.8 million or $0.03 per share in the first quarter, benefitting from the improvement in average gold price received over the prior year quarter.

Operating cash flows in the first quarter were $47.6 million, an increase quarter-on-quarter due to the stronger gold price and lower carrying costs for Didipio. This was partly offset by working capital movements from an increase in inventories at Haile. Fully diluted cash flow per share before working capital movements was $0.09 per share.

Investing cash flows of $71.9 million in the first quarter increased quarter-on-quarter with higher capital expenditure at Haile for expansion of waste storage and pre-stripping activities at Macraes as well as ongoing investment in development of the Martha Underground at Waihi.

As at March 31, 2021, the Company's cash balance stood at $145.5 million and $50.0 million remains undrawn on the credit facility.
