OceanaGold Reports Third Quarter 2023 Operating and Financial Results

(All financial figures in US Dollars unless otherwise stated)

(VANCOUVER) OceanaGold Corporation (TSX: OGC; OTCQX: OCANF) ("OceanaGold" or the

2023. The consolidated financial statements and the Management Discussion and Analysis (“MD&A”) are

available at www.oceanagold.com.

Gerard Bond, President and CEO of OceanaGold, said "The third quarter was always expected to be our

lowest production quarter of 2023, though it was further impacted by isolated challenges in the final stage

of the Mill Zone pit at Haile . However, strong performance at Didipio and Macraes keeps us on track to

meet the low-end of our full-year consolidated production guidance range. We also achieved a number of

exciting milestones across our business during the quarter: Haile produced its millionth ounce, fi rst ore

from the Haile Underground was mined, the ball mill at Macraes was comprehensively repaired and

returned to full service, and some exciting exploration results were released at Didipio and Haile. We

remain focused on safely and r esponsibly delivering on our consolidated full -year production guidance in

the final quarter of the year and have laid the groundwork for a strong 2024 and beyond."

Operations

The Company produced 99,028 ounces of gold and 3,413 tonnes of copper in the third quarter of 2023.

Third quarter gold production was 24% lower than the previous quarter and 6% lower than the

corresponding quarter in 2022. The quarter -on-quarter reduction was driven by decreased production at

Haile, with lesser contribution quarter -on-quarter also from Macraes and Waihi. The Company has

produced 347,207 ounces of gold and 10,324 tonnes of copper year-to-date (“YTD”), which was broadly

in line with the corresponding period in 2022.

On a consolidated basis, the Company recorded a third quarter AISC of $1,911 per ounce on gold sales

of 97,911 ounces and copper sales of 3,133 tonnes. This was a 45% increase in AISC compared to the

previous quarter and a 23% increase compared to the corresponding period in 2022. The quarter -on-

4

quarter increase was mainly driven by 30% lower comparative gold sales, especially from Haile. YTD the

Company has recor ded an AISC of $1,563 on sales of 349,064 ounces of gold and 9,877 tonnes of

copper. AISC exclu des the Additional Government Share of $13.9 million at Didipio for both the third

quarter of 2023 and YTD 2023 related to the Financial or Technical Assistance Agreement (“FTAA”).

Haile produced 22,961 ounces of gold in the third quarter. The 47% reduction compared to the previous

quarter was due to lower than expected grades from the lower benches of the Mill Zone pit and a planned

transition to waste stripping at Ledbetter pit; mining in Mill Zone was completed in the third quarter. Haile’s

third quarter AISC was $3,047 per ounce, a material increase compared to the previous quarter largely

driven by the lower quarter -on-quarter gold sales. YTD Haile has produce d 114,640 ounces of gold at an

AISC of $1,755 per ounce sold.

During the third quarter , first development ore was mined and stockpiled from the Horseshoe

Underground mine at Haile. First stope ore was achieved in mid -October and three production stopes are

planned to be mined and delivered to the mill in the fourth quarter of 2023.

Didipio produced 30,479 ounces of gold and 3,413 tonnes of copper in the third quarter. The 5% reduction

in gold production compared to the previous quarter was mainly due to s lightly lower grades consistent

with the mine plan. Copper production was largely flat quarter -on-quarter. Didipio’s third quarter AISC was

$872 per ounce on gold sales of 29,657 ounces and 3,133 tonnes of copper, an 18% increase on the

previous quarter du e to lower by-product credits (mainly volume related) and higher production taxes.

YTD Didipio has produced 95,720 ounces of gold and 10,324 tonnes of copper at an AISC of $727 per

ounce.

Macraes produced 34,725 ounces of gold in the third quarter . The 12% reduction compared to the

previous quarter was due to lower total mill feed with ball Mill No:2 (“ML -02”) taken down for repair in July.

The repair was completed in August and ML -02 was returned to service and operated at full capacity for

the remainder o f the third quarter. Macraes third quarter AISC was $1,550 per ounce, a 20% increase

compared to the previous quarter mainly due to the lower quarter-on-quarter gold sales. YTD Macraes

has produced 100,901 ounces of gold at an AISC of $1,611 per ounce.

Waihi produced 10,863 ounces of gold for the third quarter. The 27% decrease compared to the previous

quarter was driven by a 36% decrease in feed grade, as mining encountered additional lower grade

remnant ore material, partially offset by a 10% increase in ore tonnes mined. Waihi’s third quarter AISC

was $2,196 per ounce , a 36% increase compared to the previous quarter mainly driven by the lower

quarter-on-quarter gold sales. YTD Waihi has produced 35,945 ounces of gold at an AISC of $1,949 per

ounce.

Financial

The Company recorded third quarter consolidated revenue of $214.1 million, a 29% decrease compared

to the previous quarter largely driven by 30% lower gold sales. The decrease in gold sales reflected the

aforementioned performance at Haile, Macrae s and Waihi. Third quarter revenue was broadly in line with

the corresponding period in 2022.

The Company has YTD consolidated revenue of $759.0 million , a 4% increase relative to the

corresponding period in 2022, driven by a 14% higher realized gold pric e for the Company and an 18%

5

increase in gold sales at Macraes. This was partially offset by a 42% decrease in gold sales at Haile and

a 18% decrease in gold sales at Waihi relative to the corresponding period.

Third quarter EBITDA was $59.2 million, a 61% decrease relative to the previous quarter mainly due to

the lower revenue and the Additional Government Share of $13.9 million recognized for the first time at

Didipio, partially offset by lower costs of sales. YTD consolidated EBITDA was $311.7 million, reflecting a

14% increase compared to the corresponding period in 2022 with higher revenue and lower foreign

currency exchange losses, partially offset by higher general and administration costs including indire ct

taxes and the Additional Government Share at Didipio.

Third quarter Net Loss After Tax was $(5.5) million or $(0.01) per share fully diluted, compared with a Net

Profit After Tax of $68.6 million and $0.09 per share fully diluted in the previous quarter.

Third quarter Adjusted Net Loss After Tax was $(1.6) million or $0.00 per share fully diluted compared with

an Adjusted Net Profit After Tax of $70.4 million or $0.10 per share in the previous quarter.

YTD Net Profit After Tax was $102.0 million , a 6% increase compared to the corresponding period in

2022.

Third quarter cash flows from operating activities were $62.5 million, which was 61% below the previous

quarter reflecting both the lower revenue and EBITDA in the third quarter, in line with plan. YTD cash

flows from operating activities totalle d $289.4 million, which was 8% above the corresponding period in

2022.

Third quarter cash flows used in investing activities totalled $92.1 million, which was 3% above the prior

quarter, due primarily to higher quarter -on-quarter pre-stripping and capitali zed mining costs and growth

capital expenditure primarily related to the Haile underground mine development.

The Company’s Free Cash Flow (“FCF”) for the third quarter was $(29.6) million. YTD FCF is $26.3

million.

As at September 30, 2023, the Company’s a vailable revolving credit facilities remained at $250 million,

with $115 million undrawn following a discretionary repayment of $15.0 million during the third quarter.

The Company had immediately available liquidity of $175 million including $60.3 million in cash.

The Company’s Net Debt position, inclusive of equipment leases, increased to $ 171.6 million from $136.3

million in the previous quarter primarily due to the decrease in cash and cash equivalents as a result of

negative FCF and payment of the sem i-annual dividend. The Company’s leverage ratio was 0.41 times as

at September 30, 2023.

Outlook

Overall, the Company expects to deliver gold production within its original production range, albeit

towards the lower end of the range. Copper production an d group capital and exploration expenditure

guidance remains unchanged, with changes at the asset level offsetting each other. AISC guidance has

been lifted by $125 per ounce reflecting the impact of lower production from Haile.

The Company’s updated 2023 full year guidance is presented in the tables below.

As stated in the news release dated September 14, 2023, under reconciliation in the lower benches of the

now complete Mill Zone pit negatively impacted Haile’s production guidance for the year. However, due to

strong operating performance YTD and projected for the remainder of the year at both Didipio and

Macraes, the Company still expects to produce above the bo ttom end of the original group gold

production guidance range of 460,000 ounces , but has narrowed the top end of the gold production

guidance to be 480,000 ounces . The Company’s copper production guidance of between 12,000 to

14,000 tonnes remains unchanged.

Reflecting the lower production guidance, group cash cost guidance has increased to $850 to $950 per

ounce and AISC guidance has increased to $1,550 to $1,650 per ounce for the year.

As previously announced, full year production at Haile is expected to be approximately 25,000 ounces

below the bottom of the original guidance range, with full year production now expected to be 140,000 to

150,000 ounces of gold. Consequently Haile’s AISC will be higher and is now expected to be between

$1,950 and $2,050 per ounce.

Didipio full year production is expected to exceed the original guidance range, which has been increased

to 125,000 to 135,000 ounces of gold, with copper guidance unchanged at 12,000 to 14,000 tonnes of

copper. As a result of the higher productio n, AISC is expected to be lower than original guidance and is

now expected to be between $650 and $750 per ounce.

Through increased throughput initiatives at Macraes following the ball mill repair, Macraes is expected to

exceed its original production gu idance and is now expected to produce between 130,000 and 140,000

ounces of gold for the year. As a result of the higher production, AISC is expected to be lower than

original guidance and is now expected to be between $1,575 and $1,675 for the year.

Waihi’s 2023 production guidance of between 50,000 and 60,000 ounces of gold remains unchanged.

However, a projected increase in operating costs including contract workers and additional water

management costs means that AISC is now expected to be between $1,800 and $1,900 per ounce, which

is higher than original guidance.

7

The Company also maintains its consolidated capital and exploration expenditure guidance of between

$330 million and $385 million unchanged. However, based on the latest mine plans and the ti ming of

planned capital expenditure programs, the full year general operations capital and growth capital

guidance ranges have been reduced to $85 million to $100 million and $60 million to $70 million ,

respectively, while pre -strip and capitalized mining costs have been increased to $155 million to $170

million. Exploration expenditure guidance remains unchanged.
