Physical scale

Physical scale: Council communication 2025-211 describes a proposed roughly 600-acre land-sale scope. This is agenda-request scope, not proof of authorization, an executed agreement, a completed conveyance, developed campus acreage, building count, floor area, or capacity.

What the sources support

Butte-Silver Bow Council communication 2025-211 requested authorization for a land-sale agreement with Horizons Montana, LLC concerning roughly 600 acres in Montana Connections for development of a data-center campus. The county's current Ad Hoc Data Center Impact Committee page crosswalks Sabey to this proposed project and says Sabey received a six-month extension on February 11, 2026. An April 24, 2026 TEDD agenda still listed a Sabey/Horizons update and due-diligence extension item, without recording its result. This supports a proposed project in a land-sale and due-diligence process; it does not prove that an agreement or amendment was authorized or executed, the sale closed, ownership transferred, or any zoning, permit, construction, power, energization, or operating milestone occurred.
