Nickel 28 Releases Ramu Q4 and Full Year

2025 Operating Performance

Toronto, Ontario--(Newsfile Corp. - February 23, 2026) - Nickel 28 Capital Corp.

(TSXV: NKL)

(FSE: 3JC0)

("

Nickel 28

" or the "

Company

") is pleased to provide operational results for the quarter

ending December 31, 2025, and for the full calendar year of 2025 for the Company's largest asset; the

Ramu Nickel-Cobalt ("

Ramu

") integrated operation in Papua New Guinea. Nickel 28 currently holds an

8.56% joint-venture interest in Ramu which is operated by the Metallurgical Corporation of China

("

MCC

").

Full Year Q4 2025 Ramu Highlights:

Q4 2025 production of 8,231 tonnes of contained nickel in Mixed Hydroxide Precipitate ("

MHP

"),

compared to 5,952 tonnes in the same period last year.

Full year production of 33,007 tonnes of contained nickel in MHP, compared to 28,669 tonnes last

year.

Q4 2025 production of 777 tonnes and full year production of 3,099 tonnes of contained cobalt in

MHP, compared to 549 tonnes in the same period last year and 2,625 tonnes for the 2024 full

year.

Q4 2025 nickel sales of 8,763 tonnes and full year sales of 32,622 tonnes of contained nickel in

MHP, compared to 5,308 tonnes in the same period last year and 30,523 tonnes for the 2024 full

year.

Q4 2025 cobalt sales of 825 tonnes and full year sales of 3,061 tonnes of contained cobalt in

MHP, compared to 488 tonnes in the same period last year and 2,793 tonnes for the 2024 full

year.

Nickel inventory on hand at quarter end was 1,674 tonnes of nickel in MHP.

LME average nickel price of US$6.75/lb in Q4 2025 and US$6.88/lb for the full year.

This was a

decrease of 7% from the same period last year (US$7.26/lb) and a decrease of 10% from the

2024 average (US$7.63/lb).

Average cobalt price of US$22.48/lb. in Q4 2025 and US$16.07/lb for the full year.

This was an

increase of 126% from the same period last year (US$9.95/lb) and an increase of 43% from the

2024 average (US$11.26/lb).

Production costs, net of by-product credits, were US$4.06/lb. of nickel produced as MHP in Q4

2025, compared to US$4.17/lb in the same period last year. Full year production costs, net of by-

product credits, were US$3.47/lb, compared to US$3.33/lb last year.

2026 Production Guidance:

For the 2026 calendar year the project is targeting production and sales of 33,100 tonnes of

contained nickel and 3,100 tonnes of contained cobalt in MHP.

There are no anticipated shutdowns for the 2026 year, aside from the annual maintenance for the

three HPAL trains.

The project will undertake a full renovation of one of the two sulphuric acid plants; however, the

manager has built tanks to enable the project to purchase sulphuric acid and as a result there will

be no impact on production.

Nickel 28's Chief Executive Officer, Craig Lennon stated:

"It was another solid performance at Ramu,

both in Q4 2025 and for the full 2025 calendar year.

The project continues to demonstrate that it is

one of the most consistent nickel laterite operations currently in production, both through the mine and

the process plant, and is operated by one of the most experienced managers, in MCC.

MCC's desire

for continual improvement have seen them establish a dedicated Ramu Research Institute targeted

with finding project improvements and enhancements, to ensure Ramu is at the forefront of nickel

laterite HPAL operations.

As in prior years, costs were higher in Q4 2025 due to annual project bonuses; however, based on

industry cost curve data, on a full year basis, Ramu continues to rank in the lowest quartile of the cost

curve among nickel laterite HPAL operations. Sulphur prices, a major consumable for the project, are

currently at elevated levels and have impacted operating costs, alongside competitive pricing

tensions from nickel laterite HPAL operations (primarily) in Indonesia.

Cobalt prices have increased significantly in the second half of the 2025 year and going into 2026,

and nickel prices are following suit and increasing from recent lows.

We believe these price

improvements for both cobalt and nickel are largely attributable to policy decisions by the

governments of the DRC and Indonesia, respectively.

Their influence on production of cobalt and

nickel will continue to be a focus for the industry in the near to medium term.

The Indonesian

government's recent quota policies have contributed to tighter global nickel supply and the recent

upward pressure on nickel prices, which have approached the US$18,000/t level.

At these levels,

together with the cobalt by-product credit we achieve at Ramu and the improving payabilities we are

receiving for both nickel and cobalt, we believe the project is capable of generating strong margins.

It is worth noting that Ramu compares well with the newer HPAL plants being developed in Indonesia

in terms of operating costs, mainly because those projects are all built with a similar design to that of

Ramu; however one significant difference to some of the operations in Indonesia is that Ramu is an

integrated mine and process plant and as such is not dependent on a third parties for ore supply."

Ramu's operating performance for the period is presented below along with a comparison to the prior

year.
