With many technical service businesses withdrawing local offices, Goodz GMC is an example of a geological, mining and engineering services company which has put its future into the West Australian mining industry. Being the only national geological and mining consultancy with its head office based in Kalgoorlie-Boulder, managing director Morrie Goodz sees supporting local industry and services as a community responsibility. "We used to have fly-in/fly-out personnel, but we are now a local consultancy". The main reason for the local expansion has been the success achieved in 3D modelling of old workings to extend the mine life of existing operations, particularly the redevelopment of the Daisy-Milano gold operation - the longest operating underground gold mine in the region after KCGM's Mt Charlotte. Goodz also doubles as the Mine Manager of Milano gold mine where owner/operator Nickelseekers Mining has been ecstatic with the eight-year mine life extension and numerous target for future expansion coming from new innovative design methods employed by Goodz. "We have developed a system of merging mining, geological and computing specialists to create dynamic teams with a philosophy of taking traditional shallow underground or open pit operations to much deeper levels." Daisy Milano Mine Expansion In 2004, Goodz & Associates GMC Pty Ltd (Goodz GMC) has seen one of its greatest successes for its clients, with the acquisition option of the Daisy Milano Gold Mine by diversified miner Perilya Ltd. As Project Manager, Goodz GMC expanded production at Daisy Milano from 5,000 tpa to 50,000 tpa over three years, and designed the strategies that led to the production of 154,000 ounces of gold from ore grading 16 gpt. Innovative 3D modelling capabilities identified likely zones of repetition of high grade shoots and design of two exploration declines led to significant improvements to stope development and production. Goodz' geological team developed a new exploration model for the Kalgoorlie Southeast and Mount Monger goldfields that increased the mineral resource inventories from a six month mine life to greater than twenty years. Managing Director, Morrie Goodz, explained that the innovative methods on both the exploration and stope design fronts laid the foundations for the attraction of the project by major mining houses, with Perilya given the green light. The mine planning strategic design developed by Morrie Goodz could see the Daisy Milano mine becoming historically the largest gold producer in the Kalgoorlie South district, with extensions now going below the 550m depth. After 15 years in continuous underground production, it is now the second longest running underground operation at Kalgoorlie. Some of Goodz GMC's designs have become industry standards. In particular, their 'boxcut portal design' for surface declines has set new parameters in accepted layouts for decline portals. Environmental and Safety Management is also a key ingredient to Goodz GMC designs. All surface mining designs come with final abandonment provisions, which ensure that the client has no further technical and implementation costs. Environmental bonds are almost eliminated, making projects more feasible for small to medium sized operators trying to minimise startup costs. Future Aims - Smart Planning Having a clearly defined mission and preparing a management plan to meet corporate strategic objectives is the motto for Morrie Goodz. "Doing the preparatory footwork up front and having commitment to the plan leads to a cost effective solution and ensures success. It's hard work - and teamwork. That's how we get the job done." Making Australia's Longest Operating Mines Oldest Mine - Goodz and Associates GMC Pty Ltd (Goodz GMC) has a tradition of reopening significant historical producers and turning them into mines of the future. We had the good fortune of running Australia's longest continuously operating mine for five years, the Gaffneys Creek Gold Mine in northeast Victoria, at 132 years of operation. Goodz GMC took over the mine design, and exploration management responsibilities from 1985 to 1990. During that period, the mine went from having a 3-6 month mine reserve life to a 24-36 month reserve life, and experienced a five-fold production expansion. Conceptual models developed by the mine exploration team led to two 500m deep holes that intersected an unknown repetition of the ore host and laid the foundation to the mine expansion. New expansion - Morrie Goodz repeated this process through the implementation of mining software solutions by Gemcom to define a mineralisation corridor through the Mt Monger goldfield south of Kalgoorlie. This led to deep drilling exploration along the Milano shear zone and the identification of a 20 year resource inventory. Morrie took over mine management in 2002 and designed the development of a new decline access to replace the shaft haulage operations. When Goodz GMC commenced their involvement in the project, production was 5,000 tpa. The anticipated production for 2004-2005 will be between 150,000 and 200,000 tpa. Newest mine - The Morning Star Gold Mine at Woods Point, Victoria, operated for 101 years and produced 883,000 ounces at an average grade of 26.5 g/t. It was operated by WMC (GMA) and closed in 1963. Goodz GMC has been using 3D modelling methods on detail survey, assay and drilling records compiled by WMC, to identify a preliminary target of 4 million ounces. The mine owner, Mt Conqueror Minerals NL, is currently preparing for a deep diamond drilling programme to validate the mine model. Community Services - Sponsoring Safety and Future Providers Goodz GMC has continued its involvement in advancing mine professionalism and safety through continued sponsorship of the Chamber of Minerals and Energy Mines Rescue Competition. Goodz GMC has sponsored the First Aid and Casualty Awards and has provided staff for support services during underground mine rescue competitions. Since 1987, Goodz GMC has provided projects, financial support and supervised nine graduate and post-graduate research theses and approximately 60 student projects in earth sciences, civil and geological engineering. Waterwise Competition Mining and Environmental Consultants, Morrie Goodz and Robin Lonsdale were awarded Waterwise Garden of 2003 for their 18-month old native garden in Kalgoorlie. The garden features over 150 species including 60 Eremophila and is a testament to what can be planted in desert soils. The proprietors of Goodz GMC said most of the plant species were native to the goldfields and were commonly selected for minesite rehabilitation projects. The hardiness of native plants to drought and salty conditions aids their ability to get quickly established in a harsh and fragile rehabilitation environment. Goodz GMC has been involved in native plant propagation and site rehabilitation since the early 1990's. [ Top of Page ]
