Corporate update
Free electricity at Childress in August
Childress operated at negative realized electricity costs of ~US$0.08/kWh3.
As a result, Iris Energy was effectively paid ~$28k per Bitcoin to take power at Childress and generated a further ~$28k per Bitcoin in mining revenue (i.e. ~$56k mining profit4 per Bitcoin at Childress).
The Company was able to capitalize on heightened energy market volatility, dynamically trading Bitcoin mining profitability against electricity market pricing to drive down net electricity costs.
Targeting next-gen compute and generative AI with NVIDIA H100 GPUs
On August 29, 2023, the Company announced the purchase of NVIDIA’s latest-generation artificial intelligence (“AI”) H100 GPUs.
The initial purchase of 248 NVIDIA H100 GPUs for ~US$10 million5 is expected to be delivered in the coming months and will allow the Company to:
- Further assess the appropriateness of its next-generation data centers for servicing adjacent computing markets such as generative AI7
- Demonstrate capability to prospective customers
The update can be accessed via the following link.
Canal Flats update (0.8 EH/s, 30MW capacity) – BC, Canada
Canal Flats has been powered by 100% renewable energy since inception8.
The project achieved average monthly operating hashrate of 823 PH/s in August compared to 825 PH/s last month.
Mackenzie update (2.6 EH/s, 80MW capacity) – BC, Canada
Mackenzie has been powered by 100% renewable energy since inception8.
The project achieved average monthly operating hashrate of 2,595 PH/s in August compared to 2,583 PH/s last month.
Prince George update (1.6 EH/s, 50MW capacity) – BC, Canada
Prince George has been powered by 100% renewable energy since inception8.
The project achieved average monthly operating hashrate of 1,615 PH/s in August compared to 1,592 PH/s last month.
Childress update (0.6 EH/s, 20MW operating / 80MW 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 461 PH/s in August compared to 562 PH/s last month. This decrease was primarily attributable to energy market trading activities (mentioned above), which resulted in a lower number of Bitcoin mined but negative realized electricity costs of ~US$0.08/kWh3.
Construction of the remaining 80MW (4 x 20MW data centers) for Phase 1 (first 100MW) remains on track with mass grading civil works completed, and concrete foundations for the second data center in progress.
The Company’s ownership of key infrastructure also provides a rapid and efficient growth pathway, with 600MW of total power capacity available at the site.
Community engagement
Iris Energy sponsored the annual Flats Festival in Canal Flats, with all proceeds going towards Canal Flats’ Volunteer Fire Department to help purchase personal protective equipment, training supplies and other equipment.
The Company was also invited to attend the Lheidli T’enneh Elder’s Society’s filming of their “A Year in the Life of Lheidli T’enneh” series, to learn about traditional food, medicinal, and technological uses of plants.
Finally, the Company was honoured to receive the “Friends to 4-H” award from Childress community group 4-H, following the Company’s ongoing support in the areas of robotics and technology.
Future development sites
Development works continued across additional sites in Canada, the USA and Asia-Pacific, which have the potential to support up to an additional >1GW of aggregate capacity that can power growth beyond the Company’s 760MW of announced capacity.

Technical commentary
The Company’s lower average operating hashrate (5,493 PH/s vs. 5,562 PH/s in July) and Bitcoin mined (410 vs. 423 in July) were primarily attributable to energy market trading activities at Childress. This was more than offset by ~$2.3 million3 of power sales and was the primary driver behind the aggregate decrease in electricity costs ($4.3 million vs. $6.6 million in July) and in average electricity costs per Bitcoin ($10.6k vs. $15.5k in July) across all sites.

1 All timing references in this investor update are to calendar months, in each case unless otherwise specified.2 Bitcoin and Bitcoin mined in this investor update are presented in accordance with our revenue recognition policy which is determined on a Bitcoin received basis (post deduction of mining pool fees as applicable). Electricity costs exclude REC purchases.3 The Company’s Childress site generated ~US$2.3 million of power sales in August (~84 Bitcoin equivalent), which represents unaudited power credits (primarily driven by voluntary curtailment) under hedge contracts (based on AEP meter data and ERCOT real-time prices) and are reflected within the electricity costs. Figures are based on monthly electricity invoices received as well as internal estimates (as applicable) and exclude REC purchases.4 Mining profit calculated as Bitcoin mining revenue less net electricity costs. 5 Excludes certain components, e.g. storage and certain front-end networking components.6 Assumes purchase of Bitmain S19 XP miners. Additional miners have not yet been purchased and the Company will continue to monitor the market for purchase opportunities. Hashrate figures may change depending on miner procurement selection.7 No material modifications currently expected.8 Currently approximately 97% directly from renewable energy sources; approximately 3% from purchase of RECs.9 Comprises actual power usage for Canal Flats, Mackenzie, Prince George and Childress. Canal Flats, Mackenzie and Prince George have been powered by 100% renewable energy since inception of which approximately 97% is directly from renewable energy sources; approximately 3% is from the purchase of RECs. Childress has been powered by 100% renewable energy since inception via the purchase of RECs.10 Reflects estimated hashrate capacity by site assuming full utilization of existing available data center capacity with Bitmain S19j Pro miners, except where otherwise stated.11 Indicative timing for commencement of delivery of data centers.
