What happened
Siċaŋġu Co describes itself as the economic engine of the Siċaŋġu Lak̇ota nation. Its Legal page says it began as the Rosebud Economic Development Corporation (REDCO), a chartered entity of the Rosebud Sioux Tribe. In 2011 new leadership expanded its mission, and two legally independent but aligned organizations were created: Sicangu Community Development Corporation, a 501(c)(3), and Tatanka Funds, Inc., a Native CDFI. ProPublica Nonprofit Explorer lists Sicangu Community Development Corporation of Mission, South Dakota, with tax exemption issued in November 2019. The team page lists Clay Colombe as Chief Executive Officer.
Its Wolak̇ota page says the 28,000-acre Wolak̇ota Buffalo Range is home to over a thousand buffalo and is the largest Native-owned bison herd in the world. That is the organization's own claim. The page says the range aims to regenerate land, people and economy for the Siċaŋġu Lak̇ota Oyate, and names World Wildlife Fund and the US Department of the Interior among supporters.
A second project, Keya Wakpala Woiċaġeyapi, is a planned 590-plus acre community of culturally relevant homes and businesses for Siċaŋġu Lak̇ota people. The page invites enrolled Rosebud Sioux Tribe members to take a housing survey.
Its pages do not say who holds title to the buffalo range land. A gift to the nonprofit is a gift to the nonprofit, not to the Tribe's government.
Good to know. Siċaŋġu Co includes both nonprofit and for-profit parts; a gift goes to its 501(c)(3), not to the Rosebud Sioux Tribe's government. The size and "largest" claims for the buffalo range are its own.

Research notes. Size and 'largest' claims are the organization's own. The site also lists for-profit arms, so confirm which entity receives a gift; the donation page names the 501(c)(3). Title to the range land and the exact relationship of each entity to the Rosebud Sioux Tribe's government beyond the Legal page were not confirmed.
