CleanSpark ( NASDAQ: CLSK ) expects to more than double the size of its existing bitcoin ( BTC-USD ) mining operation as it starts construction on the second phase of its recently-acquired site in Washington, Georgia, it said Thursday. The site, purchased in August 2022, is expected to employ S19j Pro and Antminer S19 XP models, adding up to 2.2 exahashes per second (EH/s) of computing power to CleanSpark's ( CLSK ) mining capacity. That would represent up to a 34% increase from its current hashrate of 6.5 EH/s. The company said last month it exceeded its year-end hashrate target of 6 EH/s, marking a three-fold jump over the last year. CLSK dipped 1% in morning trading after rising as much as 4% earlier in the session. Previously, (Jan. 4) CleanSpark generated 13.3% less bitcoins ( BTC-USD ) in December vs. November.
