44 West Mining LLC is a Wyoming-based Bitcoin mining company formed as a joint venture between Longhorn Generation LLC and CSD Energy Advisors, combining expertise in crypto mine management, energy demand response, and private equity/investment. The company operates immersion-cooled Bitcoin mining facilities in Gillette, Wyoming (Kitty site in the Powder River Basin), utilizing abundant local energy resources with a capacity up to 20 MW. 44 West emphasizes state-of-the-art equipment, immersion cooling technology (e.g., Intelliflex™ modules), community involvement, transparency, and sustainability. Additional services include Bitcoin mining consulting/mine management (via exclusive partnership with Frontier Consulting for white-glove project development from "dirt to data center"), and an ASIC Miner Exchange platform for buying/selling new/used miners (including GPUs for other cryptocurrencies). As of late 2025 (last major updates 2024), the company reports expansions like a 3 MW immersion module deployment (March 2024, reaching ~135 PH/s and >1,000 miners), but no recent public activity indicates possible quieter operations or scaling.
