A burial was excavated from in front of the wall of the earliest version of the pyramid. The associated offerings included a number of clay vessels, a necklace of small gold bells and a copper axe. The earliest metal artefacts in the Maya region have been dated to the Terminal Classic period (c.800-900); the presence of metal artefacts associated with the earliest construction phase at Mixco Viejo (Jilotepeque Viejo) demonstrates the short span of the site and suggests that all three construction phases succeeded each other relatively rapidly. Further ceramic offerings were deposited under both of the latter two phases and an artificially deformed skull was interred under the central axis of the final version.
