A tensionable cable bolt including a length of multi-strand cable and an anchoring portion comprised of a shaft received on the cable and attached to the cable at a crimp portion comprising at least one primary crimp with at least one secondary crimp disposed within the primary crimp. The cable may include a mixing portion and the anchor portion may include an expansion anchor threaded onto the shaft. A method of manufacturing the tensionable cable bolt includes providing a length of multi-strand cable; providing an anchoring portion including a shaft; extending the cable through the shaft; and crimping the shaft to the cable to form at least one primary crimp with at least one secondary crimp disposed within the primary crimp. The method may further include threading an expansion anchor onto the shaft and/or providing a resin mixing portion along the cable.
