Assumptions and Notes


1.
Reflects USD equivalent, unaudited cash and cash equivalents as of April 30, 2024.
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).
3.
Comprises actual power usage for Canal Flats, Mackenzie, Prince George, and Childress. The Company’s Canal Flats, Mackenzie and Prince George sites have been powered by 100% renewable energy since inception of which approximately 98% is directly from renewable energy sources; approximately 2% is from the purchase of RECs. The Company’s Childress site has been powered by 100% renewable energy since inception via the purchase of RECs.
4.
Electricity costs presented on a net basis and calculated as IFRS electricity charges net of realized gain/(loss) on financial asset, ERS revenue (included in other income) and ERS fees (included in other operating expenses). Figures are based on current internal estimates and exclude REC purchases.
5.
Hardware profit margin for Bitcoin mining and AI Cloud Services is calculated as revenue less net electricity costs, divided by revenue (for each respective revenue stream) and excludes all other costs.
6.
Represents indicative electricity cost per bitcoin mined assuming 30 EH/s, nameplate fleet efficiency of 16 J/TH, weighted average power cost of $0.037/kWh ($0.045/kWh in BC and $0.033/kWh in Texas – latter calculated using actual monthly average net power price at Childress during 3Q YTD FY24 (i.e. July 2023 to March 2024), including ERS revenue and adjusted for now eligible 4CP benefit), global hashrate of 603 EH/s, block reward of 3.125 BTC per block and transaction fees of 0.3 BTC per block.
7.
Illustrative annualized hardware profit = revenue less assumed electricity costs (excludes all other site, overhead and REC costs). GPU calculations assume 1.25kW power draw required for 1 GPU, $0.05/kWh electricity costs and $2.00-2.50 per GPU hour revenue assumption. Capex assumes ~$40k per GPU.
8.
Capacity to be installed comprises Bitmain T21 and S21 Pro miner purchases and miner purchase options. Additional S21 Pro miners secured will also be used to upgrade the existing fleet. Final decisions with respect to exercising miner purchase options will be made during 2024 taking into consideration market and funding conditions.
