13 March 2009 (half-day)

Mercure Hotel, Brisbane QLD

In order to reduce the incidence of AMD/ARD, the International Network for Acid Prevention (INAP), a consortium of the major global mining companies focussed on AMD/ARD, sponsors research on ARD, and actively supports international forums, such as the International Conference on Acid Rock Drainage (ICARD), a conference that is held every 3-4 years. INAP has also commissioned the production of a Global Guide on Acid Rock Drainage (GARD), and this is expected to be released in mid 2009.

In preparation for the GARD guide release, INAP in association with ACMER (The Australasian Representative of the INAP Global Alliance) will offer a half-day GARD Guide workshop following the ‘Short Course on the Fundamentals of Acid Metalliferous Drainage’ on Friday 13 March 2009. This GARD Guide workshop invites industry and regulatory specialists in AMD/ARD and mine water management to discuss aspects of the Global Acid Rock Drainage Guide. This workshop is designed to share information regarding the development of the GARD Guide and to consult with role-players in order to obtain further regional input on specifi ed Chapters of the Guide. The feedback received from the participants will be used to improve the Guide.
