reveal the areas where he and Lasseter travelled and searched while together: the Petermann and Rawlinson Ranges, then south-west to the Warburton Range, then a zigzag course evidently following the ranges eastward to the Western Australian border ending at the Petadi rock hole at the eastern end of the Mann Range in South Australia. Almost out of supplies they then returned to Ilbilba where they parted. Geologists have made various statements as to whether or not there are gold bearing areas in this country. In 1931 geologists T. Blatchford and H.W.B. Talbot accompanying Bob Buck pronounced the region as unpromising but they only inspected the Petermann Range and the eastern end of the Rawlinson Range, travelling no farther west than Sladen Waters. In 2014 geologists W.D. Maier, H.M. Howard and R.H. Smithies likened the southern part of Lasseter's search area to the Bushveld Complex in South Africa where gold deposits do occur and said the region has high potential, quoting a 2002 report of copper-gold vein style material found north of the Cavenagh Range. Later history No maps showing the location of the fabled gold reef were ever found, and over subsequent decades the tale of the reef and its discoverer has assumed mythic proportions; it is perhaps the most famous lost mine legend in Australia, and remains a "holy grail" among Australian prospectors. Popular adventure-story author Ion Idriess, in his book Lasseter's Last Ride (1931), gives a detailed description of Lasseter's time with the Aboriginal peoples. His diary's notes were hidden from the Aboriginal peoples by being buried under camp fires. They had shunned Lasseter after their Kurdaitcha man "pointed the bone at him" – he was condemned to be ignored and no longer cared for. Another story is told in Pintupi-Luritja language and English in Laatjatanya Yanutja, available in the Living Archive of Aboriginal Languages. In popular culture Lasseter's Reef became a famous Australian folk tale. It inspired a sub-plot in the film, Strike Me Lucky (1934), and Lasseter's fate was recreated in the movie Phantom Gold (1936). In 1974, Bill Gill Productions and Australian Film School worked on a film version of Lasseter's Last Ride. Two songs are titled "Lasseter's Last Ride"; the first by Peter Dawson and Edward Harrington and performed by Peter Dawson (May 1940), and the second by Dean Thomas (September 2012). Other songs dealing with the subject include: "Lasseter" (James Hermel), "Lasseter" (William
