The new 1.2 million tonnes-per-annum Stage 3 Expansion Process Plant has continued to perform well since the commencement and completion of commissioning in September and December 2025, respectively. Record quarterly mine development of 3,007 metres (a 21% increase from Q1 2025), including a new monthly development record of 1,067 metres in March 2026, with lateral development rates now exceeding the Stage 3 Expansion requirement of 1,000 metres per month. Subsequent to quarter end, the Company achieved a new monthly development record of 1,109 metres in April.

Quarterly total material mined (ore plus waste) of 378,430 tonnes and quarterly ore mined of 154,104 tonnes, with long hole open stoping performing to design, and record quarterly tonnes to surface of 410,356 tonnes, highlighting the positive impact of the first material pass, the commencement of surface trucks operating in the Twin Incline and the completion of the Decline-Incline Convergence Project connecting the Main Mine with the Twin Incline via internal ramp access in late January 2026. Financials Record cash and cash equivalents totaling US$287.0 million, including a record US$242.6 million net cash position. Record quarterly revenue of US$236.3 million, an increase of 63% from Q1 2025.

Record quarterly net income of US$116.6 million or US$0.48 per share, an increase of 66% from Q1 2025. Sales of 44,854 oz gold, 1,874,270 lbs copper and 41,467 oz silver. Gold concentrate and doré inventory of 12,318 oz as of March 31, 2026, a decrease of 1,713 oz over the prior quarter.

Record operating cash flow (before working capital adjustments) for the three months ended March 31, 2026, of US$132.9 million or US$0.54 per share, and record earnings before interest, taxes, depreciation and amortization (“ EBITDA ”) ( 3 ) of US$179.9 million or US$0.74 per share, a 64% and 68% increase from Q1 2025, respectively. Growth As at March 31, 2026, 96% of Stage 3 Expansion growth capital has either been spent or committed and remains on budget. During Q1, significant progress was made on key pastefill infrastructure projects including the Underground Pastefill Plant, Surface Tailings Filtration Plant, Binder Blending Plant and Filter Cake Storage Facility.

First tailings filter cake production from the Surface Tailings Filtration Plant was delivered in late April and commissioning is ongoing. Detailed civil and concrete works at the Binder Blending Plant are now complete, with structural steel erection of the Filter Cake Storage Facility underway and expected to be completed in Q3 2026. At the Underground Pastefill Plant, concrete pours are well advanced across the 1205 Level, with silo lining concrete works ongoing.

Practical completion of commissioning of the pastefill circuit is scheduled for Q4 2026. During the quarter, several key Stage 3 Expansion underground construction and operational excellence projects were completed or are approaching completion, including: Decline-Incline Convergence Project – Completed in late January 2026, connecting the Main Mine with the Twin Incline via internal ramp access, enabling one-way traffic flow across all mining fronts. Phase 3 Ventilation Upgrade – Surface breakthrough of the Puma Ventilation Drive achieved in late February 2026, increasing primary mine airflow from 200 m³/s to 350 m³/s (+75%) and meeting initial Stage 3 Expansion airflow requirements and further reducing blast re-entry times.

Stage 4 Expansion Primary Ventilation Upgrade – HV Electrical works advancing with electrification scheduled for completion in mid-2026, upon which primary airflow capacity is expected to increase to approximately 600 m³/s (expandable to ~700 m³/s), exceeding Stage 4 and life-of-mine requirements. To conserve power, the variable speed drive fans will initially operate at ~350 m³/s and ramp up incrementally as required. Upon completion of the project, twin incline traffic will be reconfigured to highly productive one-way traffic flow.

Major Fleet Expansion – Three additional Sandvik 517i underground loaders commenced operation in Q1 2026, with a further unit arriving in Q2 2026, resulting in a net increase of three loaders. Six new 60-tonne surface trucks are scheduled to arrive in mid-2026, hauling directly from the Twin Incline to the process plant, with two additional units arriving by year-end. Two new Sandvik 45-tonne underground trucks are also scheduled to arrive in Q4 2026, replacing high-hour units.

A new Sandvik DL 432i long-hole production drill rig was also commissioned in late April, replacing an older unit, to further improve equipment reliability and increase production capacity. A new Sandvik DD 422i jumbo is scheduled to arrive in late-2026, expanding the jumbo fleet and development capacity. Primary Power Station – Phase 2 expansion to 15.3 MW (from 10.7 MW) is well advanced with all major electrical infrastructure installed and commissioning expected to be completed in Q2 2026, providing increased standby power capacity meeting Stage 4 Expansion requirements.

Two new mining fronts have been substantially developed, with five sublevels on the Twin Incline mining front and four sublevels on the Lower Kora mining front. Stope production from Lower Kora commenced in April 2026, introducing a second mining front ramping up which is expected to significantly increase operational and throughput flexibility. Major surface haul road and river crossing projects advanced significantly during the quarter, including the completion of the Baupa Bridge in early April 2026, with the Kasese river crossing and Kokomo bridge projects progressing toward mid-year completion.

Together with ongoing haul road widening and straightening upgrades, these projects will enable a tripling of surface truck payload capacity from 20 to 60 tonnes at notably faster cycle times, delivering cost savings via economies of scale and meeting Stage 3 and 4 Expansion throughput requirements. Second material pass vertical development (5-metre diameter, 200-metre vertical) is complete from the 1110 level to the 910 level (Twin Incline), with civil construction works underway, targeting operation in late-Q2. This will enable a dedicated material pass for ore and waste, respectively, providing a considerable boost to our material handling capabilities in the Main Mine and Lower Kora.

Development of a third material pass is planned to commence mid-year, to further enhance our material handling capabilities. The Company’s interim consolidated financial statements and associated management’s discussion and analysis for the three months ended March 31, 2026 are available for download on the Company’s website and under the Company’s profile on SEDAR+ (www.sedarplus.ca). All amounts are in U.S. dollars unless otherwise indicated.

The Stage 3 Expansion process plant performed well in its first full quarter following completion of commissioning in December, with gold recoveries exceeding the Updated DFS by 2.5% and copper recoveries in line. Underground, multiple key milestones were achieved, including completion of the internal ramp connecting all mining fronts to the highly productive twin incline in late January, and the surface breakthrough of the Puma Vent Drive in late February, increasing primary ventilation rates by 75%.

Completion of these projects supported record development performance during the quarter, including a monthly record of 1,067 metres in March. Subsequent to quarter-end, a further monthly record of 1,109 metres was achieved in April, marking consecutive monthly records, with development rates now exceeding the Stage 3 Expansion requirement of 1,000 metres per month. Additional key expansion enabler projects remain on track for completion mid-year, including the mine-to-mill haul road upgrade and river crossings, and haulage fleet expansion, which together are expected to triple truck payload capacity and significantly reduce haulage costs, as well as the second material pass and further ventilation and power upgrades.

Together with ongoing fleet expansion and additional mining fronts coming online, we expect production to be the strongest in the second half of the year and reiterate our 2026 production guidance. On pastefill, initial filter cake production was achieved in late April, with practical completion of commissioning of the circuit planned for the fourth quarter. With a record net cash position and the vast majority of Stage 3 Expansion capital already invested and the project remaining on budget, we are well positioned to continue executing on our growth strategy, advance the Stage 3 and Stage 4 Expansions, and unlock the broader potential of Kainantu through exploration, with a more than 50% year-over-year increase to our exploration budget.” Notes: (1) AuEq in Q1 2026 is calculated based on: gold $4,717 per ounce; silver $78.37 per ounce; and copper $5.77 per pound.

AuEq in Q1 2025 is calculated based on: gold $2,855 per ounce; silver $31.73 per ounce; and copper $4.26 per pound.
