Atlantic Nickel announces another record financial and operational performance in 2022

LONDON,Feb. 1,2023 -- Atlantic Nickel ("Atlantic Nickel" or the "Company") and Appian Capital Advisory LLP ("Appian") are pleased to announce another record year of operational and financial performance at the Company's Santa Rita nickel sulphide mine ("Santa Rita" or the "Mine") located in Bahia,Brazil.

Santa Rita is one of the very few long-life nickel sulphide mines in operation globally,boasting 34 years of mine life producing between 20-35 ktpa NiEq contained in concentrate. Based on an NI 43-101 technical report completed in 2021,the operation mines anopen-pit with a minimum 8-year life and an NPV8 of US$570m,and transitions to an underground sublevel caving operation for another 27 years with an NPV8 of US$812m. Capital expenditure for the underground is expected to be fully funded out of operating cash flow.

Separately,Appian owns Mineracao Vale Verde ("MVV") and its Serrote copper-gold mine in Alagoas,Brazil ("Serrote"),which completed construction ahead of schedule and under budget and achieved first production in 2021. In 2022,its first full-year of ramp-up,MVV achieved 105% nameplate capacity with no additional capital expenditure and generated US$60m in EBITDA. A fuller MVV operational update will be covered in a separate release.

Atlantic Nickel 2022 performance highlights

Industry leading ESG and safety performance with a Lost Time Injury Frequency Rate of 0.18 over the last 12 months (compared to 0.20 in 2021)

Strong financial growth with US$210m of EBITDA (2021 US$127m) on US$406m of revenue (2021 US$289m)

C1 cost of US$4.22/lb Ni maintains the Company's position as a consistent first quartile producer

Hedging program secures forward pricing of >US$13.00/lb on a significant share of payable nickel produced through the end of 2023

Paulo Castellari,CEO of Appian Capital Brazil commented:

"2022 was a fantastic year for Atlantic Nickel. The quality of the asset and the expertise of our team has delivered excellent financial and operational results.

Importantly,we continue to lead the industry on safety and environmental standards,with a particular emphasis on providing the best-in-class safety culture and awareness at Santa Rita. As one of the leading nickel sulphide mines globally,with a C1 cost position maintaining the Company's position as a consistent first quartile producer,we are able to continue to deliver significant returns for our investors.

We look forward to continuing the development of the underground expansion at Santa Rita,as we capitalise on the site's full potential."

Safety

Santa Rita continues to operate as one of the safest operations globally with a Lost Time Injury Frequency Rate ("LTIFR") of 0.18 achieved over the last 12 months,an improvement on the strong LTIFR performance of 0.20 in 2021[1]. The Company's Visible Felt Leadership program resulted in over ~4,400 incident prevention safety measures,helping to convey safety as a top priority of Atlantic Nickel's management. Over 170,000 man-hours of safety,health and environmental training were conducted in 2022 which have contributed to the best-in-class safety culture and awareness on site at Santa Rita.

Operational update

Significant improvements in performance were delivered in 2022,including:

6.6Mt of ore mined from the open pit alongside 30.6Mt of waste,reflecting record mining rates and excellent progress on stripping

6.6Mt of ore fed to the mill,reflecting the highest annual throughput achieved since operations at Santa Rita first began back in 2009

Ore fed to the mill at average feed grades of 0.30% NiS and 0.10% Cu

80.8% NiS recoveries were achieved at the plant

117kdmt of concentrate produced at average concentrate grades of 13.6% Ni and 4.2% Cu with cobalt,gold,palladium and platinum by-products

The first quartile C1 cost performance of US$4.22/lb Ni,net of by-product credits is driven by:

Mining costs of US$3.36/t mined

Processing costs of US$6.14/t processed

Site general and administrative costs of US$1.46/t processed

Downstream charges and transportation costs of US$1.77/lb payable Ni

By-product credits of US$1.49/lb payable Ni

All-in sustaining cost performance of US$8.41/lb Ni,net of by-product credits is also driven by:

Corporate general and administrative costs of US$1.13/t processed

Royalties of US$0.64/lb payable Ni

Sustaining capital expenditure of US$3.29/lb payable Ni,reflecting excellent progress on dam construction and capitalized stripping

Financial update

Over 2022,12 shipments of concentrate were made to the Company's offtake partners resulting in revenue of US$406m with average realized commodity prices of US$12.23/lb Ni and US$3.70/lb Cu. EBITDA and capital expenditure for the period was US$210m and US$100m,respectively. This builds on the record financial performance in 2021,when Atlantic Nickel posted US$127m of EBITDA on US$289m of revenue.

In response to the highs witnessed in the nickel and copper markets in March of 2022,Atlantic Nickel initiated an opportunistic hedging program. The following non-deliverable forward contracts were entered into to sell throughout 2022:

5.7kt,or 12.6mlb,of nickel at an average forward price of US$13.17/lb

1.8kt,or 4.0mlb,of copper at an average forward price of US$4.52/lb Cu

Realized gains from these contracts,which amounts to US$35m,are excluded from the US$210m of EBITDA achieved in 2022.

Further,as of the date of this press release,the following contracts have been entered into to sell throughout 2023:

6.8kt,or 15.2mlb,of nickel at an average forward price of US$13.07/lb

1.2kt,or 2.6mlb,of copper at an average forward price of US$4.35/lb

Progress on the underground expansion

The Company remains firmly committed to advancing the underground project. Over US$17m was invested in 2022 towards the execution a 35,000m drill program and progressing studies which will be required to declare a reserve.

An underground variability sampling campaign has been conducted in 2022. 45 samples were prepared consisting of 40 variability samples and 5 composites,with each composite representing a different 5-year period in the underground mine plan. Locked cycle test on the 5 composites resulted in NiS recoveries ranging from 84.8% - 90.6%,supporting the prospect of even higher plant recoveries when processing feed with higher NiS grade from the underground operation.

Atlantic Nickel is continuing the development of the underground expansion in 2023 and aims to deliver a Prefeasibility Study by the end of the year.

Lastly,the Company continues to advance its regional exploration with its primary focus being the drill out and declaration of a resource at Palestina,the most advanced open pit exploration target. Palestina sits approximately 25 km from Santa Rita with easy access to Santa Rita's existing processing infrastructure.
