In a press conference on 25 April 2010, NAMI announced that an October 2009 expedition had excavated and filmed the wood structure discovered by Ertuğrul. Although NAMI's website claimed Ertuğrul discovered the site in August 2006, he stated at the press conference that he learned of it in June 2008. The wooden structure reported by Yuen and Li in 2004 was not addressed. According to NAMI, specimens from the site were carbon-dated to 4800 BP. Footage of the interior of the structure was released on NAMI's YouTube account. NAMI said that Turkey would submit the location for designation as a World Heritage Site; however, when reached for comment a spokesperson for UNESCO said that the organization had not received such a request.
