Bitcoin (CRYPTO: BTC) mining stocks CleanSpark Inc (NASDAQ:CLSK) and Riot Platforms Inc (NASDAQ:RIOT) are seeing increased attention Thursday after the companies released mining updates for September.

What's Going On With CLSK: CleanSpark said it mined 493 Bitcoin in September, up from 478 in August. The company has now mined a total of 5,079 Bitcoin year-to-date, bringing its total Bitcoin holdings up to 8,049 as of Sept. 30.

CleanSpark sold 2.5 bitcoin last month at an average price of approximately $58,287 per coin. The company had an average hashrate of 23.4 EH/s for the month, resulting in an average of 16.43 Bitcoin mined daily. CleanSpark noted that it had a peak hashrate of 27.6 EH/s in September before Hurricane Helene impacted its operations at the end of the month.

CleanSpark noted that it experienced no material damage to any site infrastructure and is not aware of any material losses related to its mining servers. As of Oct. 2, all but 45 MW of power had been restored to the company's sites. The remaining 45 MW is expected to be restored "in the coming days."

"Our expansion efforts have not slowed down, and we are actively racking miners at newly acquired sites and at our existing facilities as part of our fleet upgrade plan," said Zach Bradford, CEO of CleanSpark.

Through these efforts, we expect to reach 30 EH/s during October 2024. Looking ahead to fiscal year 2025, we are positioned to rapidly achieve our forecasted growth to 50 EH/s and beyond. We look forward to providing further updates on 2025 in the coming weeks."

What's Going On With RIOT: Riot Platforms also announced its mining metrics for September on Thursday. Riot said it mined 412 Bitcoin last month, up 28% from 322 in August.

"This increase in production was driven by an increase in average operating hash rate across all our facilities and was achieved despite periodic curtailment that took place through our participation in the final month of ERCOT's Four Coincident Peak (4CP) program for 2024, whereby we paused mining operations during periods of high demand on the grid," said Jason Les, CEO of Riot.

Riot had an average operational hashrate of 19.5 EH/s during the month, up from 14.5 EH/s in August.

"We are excited about the results we are seeing from our growing hash rate and operational improvements, which are directly translating into increased production and improved efficiency. Following the completion of our third 100 MW building, Building B1, at our Corsicana Facility during the month, we achieved a total deployed hash rate capacity of 28.2 EH/s," Les said.

CLSK, RIOT Price Action: At the time of publication, CleanSpark shares were down 1.93% at $8.62 and Riot shares were down 0.28% at $7.28, according to Benzinga Pro.
