AU GOLD CORP REBUILDING HISTORIC MINING DATABASE AT ITS HAVELOCK GOLD-ANTIMONY PROJECT IN VICTORIA, AUSTRALIA

Au Gold Corp. has engaged Clive Willman & Associates to research and reconstruct historical mining activity on the Shaw-McFarlane line of workings at Havelock gold-antimony project in Victoria, Australia.

Marc Blythe, Au Gold's founder and chief executive officer, stated: "We are delighted to have Clive assist us with reconstructing the locations and extent of the historic mines on the Shaw-McFarlane trend (SMT). Portions of the SMT have been farmed, hiding or destroying geological evidence. While some of the larger historical mine dumps are preserved along the SMT, the extent of the workings can only be established from detailed historic records. Clive has successfully reconstructed historic workings on other projects by identifying, reviewing and collating historic data from a range of sources, including microfilm, archived newspapers and company records."

Output from Mr. Willman's work is expected to allow the generation of cross-sections, long sections and three-dimensional representations of the historical workings along SMT. It is likely that detailed plans and sections were created during mining in the late 1800s, however, with the passage of time, these documents have been lost.

Au Gold plans to use these reconstructed records to guide its upcoming drill program on targets that were documented as historically productive and along strategic portions of the SMT.

Mr. Willman, who holds a master's Degree in structural geology from Monash University, has had extensive industry experience in addition to 21 years with the Geological Society of Victoria as a senior geologist. He mapped across central and eastern Victoria with the survey and lives less than an hour drive from the Havelock project.
