  • Overall fleet efficiency to improve to 24.8 J/TH

• H2 2024 – pathway from 10 EH/s to 20 EH/s
  • 1 EH/s of Bitmain T21 miners purchased
  • 9 EH/s of additional Bitmain T21 miner purchase options at $14/TH
  • Overall fleet efficiency to improve to 21.9 J/TH

• Childress construction progress
  • Phase 1 (expansion to 10 EH/s) – on track for H1 2024
  • Phase 2-3 (expansion to 20 EH/s) – site civils & procurement underway for H2 2024 completion

Corporate update 

During the month, the Company provided updates on its near-term expansion to 10 EH/s and pathway to 20 EH/s in 2024.

On January 16, 2024, the Company announced it entered into an agreement with Bitmain to secure 10 EH/s of new T21 miners in 2024 at a fixed price of $14/TH/s⁴, comprising 1 EH/s of additional miner purchases and 9 EH/s of miner purchase options exercisable in H2 2024.

If the miner purchase options are exercised in full, overall fleet efficiency for 20 EH/s would improve to 21.9 J/TH. Decisions with respect to exercising all, some or none of the miner purchase options will be made during 2024, taking into consideration market conditions, shareholder value and funding availability.

Canal Flats (0.8 EH/s, 30MW capacity) – BC, Canada
Canal Flats has been powered by 100% renewable energy since inception⁵.
The project achieved average monthly operating hashrate of 838 PH/s in January compared to 829 PH/s last month.

Mackenzie (2.6 EH/s, 80MW capacity) – BC, Canada
Mackenzie has been powered by 100% renewable energy since inception⁵.
The project achieved average monthly operating hashrate of 2,578 PH/s in January compared to 2,574 PH/s last month.

Prince George (1.6 EH/s, 50MW capacity) – BC, Canada
Prince George has been powered by 100% renewable energy since inception⁵.
The project achieved average monthly operating hashrate of 1,498 PH/s in January compared to 1,568 PH/s last month. During the month, the operations team conducted scheduled substation maintenance work at Prince George.

Childress update (1.1 EH/s, 40MW operational / 260MW under construction) – Texas, USA
Childress has been powered by 100% renewable energy since inception via the purchase of RECs.
The project achieved average monthly operating hashrate of 727 PH/s in January compared to 604 PH/s last month, with the increase due to the installation of miners as part of the near-term expansion to 10 EH/s.
Construction at Childress is progressing ahead of schedule:

• Phase 1 (100MW)
  • DC 1: operating since April 2023
  • DC 2: energized with miner installation commenced; approximately 0.5 EH/s operational
  • DC 3: building and miner racking installation complete; electrical installation ongoing
  • DC 4: building structure complete; miner racking and electrical installation ongoing
  • DC 5: concrete foundations complete; building structure assembly ongoing
• Childress Phase 2-3 (200MW)
  • Site civil works commenced for Phase 2
  • Electrical procurement underway, including first 138kV transformer on site and second 138kV transformer on order

Future development sites
In addition to the Company’s 2,160MW of announced power capacity, development works also continued across additional sites in Canada, the USA and Asia-Pacific, which have the potential to support up to an additional >1,000MW of aggregate capacity.

Community engagement
Iris Energy hosted Texas Senator Charles Perry on a tour of the Childress data center facility, which showcased the Company’s commitment to creating local jobs, contracting local suppliers and investing in the community.

Operating and financial results

The operations team conducted scheduled substation maintenance work at Prince George in early January which resulted in a temporary reduction in operating hashrate.

Technical commentary

The Company’s average operating hashrate was 5,642 PH/s in January (compared to 5,576 PH/s in December) with the increase due to installation of miners at Childress. The Company recorded lower revenue ($14.5m vs. $17.2m in December) which was primarily attributable to lower network transaction fees.

The increase in electricity costs per Bitcoin mined ($18.7k vs. $14.9k in December) was primarily attributable to lower network transaction fees as well as higher electricity prices and reduced market volatility at Childress (lower energy trading proceeds), noting the Company retains flexibility to reduce future power costs through adjusting miner output in response to changes in mining economics.
