Compass Mining unveils fourth Iowa bitcoin mining site, eyes full build-out in late 2025

Compass Mining unveiled Tuesday the Phase 1 launch of its new five-acre bitcoin mining facility in Iowa, its fourth in the state. The facility currently houses 8 megawatts (MW) of operational power, ahead of full capacity construction, which is expected to begin in late 2025, according to an official announcement.

An increase in MW should translate into more BTC mining power for the firm. Energy is essential for running powerful computers with Application Specific Integrated Circuits (ASICs). These ASIC-equipped setups, commonly known as mining rigs, enable individuals and entities to solve complex mathematical problems required to validate Bitcoin transactions, secure the network, discover new blocks, and earn BTC as a reward. This is known as proof-of-work, the consensus mechanism behind bitcoin.

Nicknamed “Iowa 4,” the latest site follows Compass Mining’s launch of a hydro-cooled mining operation in North Dakota. Compass also expanded “Iowa 3” to support an additional 3,000 BTC mining rigs.

Compass Mining’s recent push came after a turbulent 2022. Back then, the firm witnessed leadership exits and staff cuts following “multiple setbacks and disappointments.” Also, disagreements with one of its hosting providers, Dynamics Corp, led to a court battle. By late 2022, Compass had recovered its miners from the firm and won a $1.47 million payment as it sought to get back on track.

The company said it energized nearly 50 MW across Indiana, Iowa, Ohio, Kentucky, Nebraska, and Texas in 2024 alone. "Expanding our self-owned infrastructure is a crucial step in strengthening Compass Mining’s position in the bitcoin mining hosting industry," CEO Paul Gosker said in a statement.

Compass Mining is one of several service providers within the U.S.-based BTC mining scene, which dominates the global industry. A Cambridge University study found that the United States accounts for over 75% of the world’s bitcoin mining activity.
