The story of the naming of the "the Great Boulder" is told in "The Mile that Midas Touched" (G. Casey & T. Mayman) - In 1893 in Dashwoods Gully in South Australia four men discussed the future of a local mining lease 'The Boulder'. Its main features were large sandstone boulders in which were found some small wiry stringers of gold. W.G. Brookman and Charles de Rose had been working the lease without much success, and George Brookman, a businessman who was backing them, had gone to Dashwood's Gully with an experienced prospector, Sam Pearce to discuss the matter. Later George Brookman told them he might be able to raise funds in Adelaide to send a small party to Coolgardie, and later the Adelaide Prospecting Company was formed. W.G. Brookman and Sam Pearce left Adelaide on the 7 of June 1893. On the last stage of their journey they walked beside their cart and two horses for 300 miles to Coolgardie. Sam Pearce had a good knowledge of geology and he and Brookman moved their camp to Ivanhoe Hill. While Brookman was away at Coolgardie applying for 20 acres Pearce discovered a rich lead a few chains away and in August they registered another lease. With memories of their Dashwood's Gully lease they called it the Great Boulder.
