        Expansion of Coking Coal Testing Facilities

                                    Coal Technology

                  ALS's Coal Utilisation business unit supplies specialised pilot scale
                  testing and consulting services to Australian and International Coal
                  Companies. The unit comprises 2 groups, the Combustion Technology
                  Centre (testing and assessing thermal coals for applications in power
                  stations), and the Coking Research Centre (testing and assessing coking
                  coals for use in steel making) which includes ALS Coal's petrography
                  laboratory (vitrinite reflectance, maceral analysis, coke microtextures and
                  specialised interpretive reports).

                  The Coking Research Centre has over 30 years experience in testing and
                  assessing coking coal quality by using equipment designed to simulate
                  the coal to coke transformation experienced in industrial scale coke
                  works. Drum testing equipment and NSC reactivity rigs are used to test
                  the produced coke to predict blast furnace performance. The section
                  comprises a team of coke making and coke testing specialists led by Phil
                  Bennett and Narelle Burns who have detailed knowledge of various
                  carbonisation processes. The specialists can perform a technical
                  evaluation of test coal's performance compared to other Australian and
                  International coking coals using the Barlow Jonker database combined
                  with an inhouse database. Interpretive reports are tailored to clients

                  In response to the high demand for pilot scale coke testing experienced in
                  recent years ALS Coal has significantly increased the coke testing
                  facilities at the Coking Technology centre, located in Ipswich,
                  Queensland, Australia. The expansion involved designing and building
                  new test equipment including an additional 450kg Pilot Scale Coke Oven
                  and an additional NSC Reactivity Rig. Increase workspace was created
                  by building a dedicated shed for drum testing equipment (with a
                  specialised dust collection system) and a dedicated shed to house the
                  reactivity rigs. A networked control system allows coking technicians
                  and specialists to monitor, control and download trend information for
                  the ovens and reactivity rigs from any location on the network.

                  The expanded facility will decrease sample turnaround time and be
                  capable of progressing large scale projects and research programs within
                  a shorter time frame to meet client's schedules. Computers will be
                                   introduced to the testing sheds over the next 12 months to allow data
                                   capture of mass balance readings directly into a coking database.

                                   The coke testing facilities at Ipswich include
                                      • 2 x pilot scale coke ovens (450kg) both fitted with a moveable
                                         wall for measurement of wall force,
                                      • 2 x bench scale coke ovens (10kg single, 20kg duplicate),
                                      • 3 x NSC Reactivity rigs,
                                      • Drum testing equipment includes JIS, ASTM, Micum (BS and
                                         AS), Modified Micum and Irsid

                                   Significant health and safety improvements were incorporated with the
                                   expansion including
                                      • Improved staff safety by decreasing ambient dust levels through
                                           new dust collection systems
                                      • Improved staff safety by reducing exposure to volatile emissions

                                           capacity afterburner to burn off volatiles released during the
                                           coking process
                                      • Specially designed coking comp table used to size and produce
                                           duplicate samples for drum testing.

                                  The coke testing facilities are complemented by the Ipswich Coal
                                  Laboratory, the largest borecore coal testing laboratory in the southern
                                  hemisphere. The laboratory performs a full range of laboratory
