MBGS undertook the exploration and geological reporting for the German Creek tender for Austen & Butta and Capcoal. When the German Creek area was granted in 1977, John and Kerry managed the exploration, and our involvement continued for two more decades.
- Nickel exploration in WA (Kingsway Minerals).
- Copper, lead and zinc exploration in central and western NSW (Mt Hope Minerals).
- Uranium mapping at Mary Kathleen mine.
- Exploration and a trial underground coal mine at Sukunka in the Rocky Mountains, BC, Canada.
- Purari River, Papua New Guinea.
In 1980 Kerry travelled to Antarctica with Cliff and Toby Rose to map areas with coal-bearing strata in the “Dry Valleys” and in 1982 John and Kerry went back to extend the mapping with New Zealand geologists. Almost 5000 sq. km of Antarctic coalfields were mapped under MBGS team presence.
The experience gained at German Creek enabled the company to secure significant exploration projects in Queensland, Tasmania and Thailand.
- German Creek coal exploration continued, and our involvement was quite diverse, including the selection of the area for the Middlemount township and design of the golf course.
- Bowen Basin coal exploration continued at Lake Lindsay, Gordonstone, Valeria and Winchester South.
- Numerous Oil Shale projects in Qld, NSW, WA, SA.

MBGS managed large exploration programs for sapphires throughout NSW (Glen Innes, Inverell, Tumbarumba, Barrington Tops) and QLD (Lava Plains, Atherton, Cheviot Hills, Lakeland Downs), as well as in China (Shandong) and Vietnam.
This decade saw the expansion of the company thanks to the increase of coal exploration in Australia and around the world. MBGS supported exploration activities in numerous deposits in NSW and QLD.
The company’s geological operations were expanding in Queensland and our Brisbane office was opened in 1993. Senior Geologist Rowan Johnson was appointed manager of the Qld office.
- Coal exploration in the Hunter Valley coalfields, with major projects at Warkworth, Bengalla, Howick, Dartbrook, Ravensworth West, Cumnock South, Saddlers Creek, Mt Arthur North
- Western Coalfield – all geological aspects of Ulan Coal Mine were managed by MBGS and our involvement continued well into the 2010s.
- Gunnedah coalfield – Maules Creek.
- Queensland Dept. Minerals and Energy contracted MBGS to assist the preparation of technical summaries of Central Qld land areas released from RA55 for competitive tender.

- Laura Basin – Bathurst Range.
MBGS provided support for active underground coal operations through mapping at Southland, Dartbrook and Cumnock in the Hunter Valley, NSW. Design and generation of high-quality longwall hazard plans became the final output from underground mapping.
The 1990s saw computer modelling of geological deposits develop rapidly and become firmly established in Australia. In response MBGS started its computer modelling team with the early models largely built using Minex and Vulcan software.
The main geological models in this decade included:
- Mt Owen, Dartbrook and Ulan – NSW
- KPC – Indonesia
- Major seam recorrelation project and model build for Kaltim Prima, Kalimantan.
- Multiple due diligences and geological support that extended into the next decade.
- Study of thin seam underground mines in West Virginia.
- Review of Merit-Pila Coal Mine, Sarawak, Malaysia
In 2000, ASIMS began as a joint initiative between MBGS and Seedsman Geotechnics to supply high-quality acoustic scanner interpretation to the coal industry.
By the late 2000’s the seemingly ever-increasing rise in the coal price generated an industry wide coal boom. MBGS geologists were busy both internationally and domestically in very remote places, as well as in established coal mining areas.
- Resource reporting in accordance with the JORC Code
- During the 2000s and into the 2010s, MBGS reported most coal resources owned by Xstrata/Glencore in Australia, Canada and Colombia.

The coal boom also brought to light complex coal deposits that required computer modelling to reflect difficult geological interpretations. MBGS was at the forefront of 3D fault modelling in Minex and Vulcan in some very interesting but very complex places:
- Prodeco and Cerrejon in Colombia.
- Shinejinst and Zeegt in Mongolia.
- Mt Owen and Gloucester in NSW.
The 2000s saw Mongolia coal exploration boom and MBGS was there at the beginning. MBGS carried out an extensive review and site investigations of all major and many minor coal occurrences throughout Mongolia. These surveys led to our involvement in exploration on the ground, building complex geological models and reporting resource estimates:
- Baruun Naran, South Gobi Sands, Gobi Coal, Tavan Tolgoi, Ovoot, Nuurstei and Khar Servegen.
- Due diligence studies and coal basin reviews for most of the coal deposits in Mongolia.
Work in China over this decade consisted mainly of Due Diligences…and there were a lot! China was implementing its stated policy of amalgamating or closing ‘village’ mines that produces less than 30,000 t/pa. MBGS reviewed approximately 70 underground and open cut mines, covering the major coal basins in China, including Heilongjiang, Shanxi, Shaanxi, Nei Mongol and Hebei Provinces.
International interest in Africa’s coal deposits increased in the 2000s due to the coal boom. High raw ash coal with clean coal coking properties was gaining attention. MBGS was involved in exploration at Benga, Mozambique for Riversdale.
Major seam correlation and domaining project in the Surat Basin, QLD.
With the boom, due diligence work around the world expanded exponentially in China, Indonesia, Mongolia, South Africa, Australia, Russia, Poland, South and North America.
- MBGS assisted Glencore with the geological development of Cerrejon, Calenturitas and La Jagua mines in Colombia.
- Geological support, management of large exploration programs, built geological models, estimated and reported coal resources that increased resources and life of mine of both Prodeco and Cerrejon coal mines in Colombia.
- Review of numerous coal deposits, project areas and working coal mines throughout Colombia including Catatumbo, Pribbenow, Magdalena Valley, San Luis, Cerro Largo, El Hatillo, La Francia, Las Carmelitas, El Descanso.
- Underground support for Ulan Coal Mine continued for numerous years – Western Coalfield, NSW.
- Open cut geological support – Gloucester NSW.
The rapid drop in coal price severely impacted the coal mining industry and MBGS was not excluded. But thanks to very loyal clients our company survived and recovered from this weak resource’s economy.
Coal exploration diminished in Australia, but overseas exploration remained buoyant in Canada, Alaska, Mozambique, Colombia and Mongolia.

MBGS provided high level support for large mining companies including Glencore and Yancoal Australia. Our involvement covered an extensive range of strategic advice, project reviews, exploration program design and planning, resource estimation and C.P. reporting.
With 50 years’ experience in the industry we have created ways to hold our team together through difficult times in the mining industry. With the support of our many long-term clients/partners we look forward to providing our services well into the future.
MBGS believes that investment in coal will continue well into the future as coal plays a critical role not only to development of emerging economies but also to ensuring a smooth transition to renewable energy sources. Alongside thermal coal’s vital role in electricity generation, coking coal is, and will continue to be crucial in the steel making process for building modern infrastructure such as transport systems and high-rise buildings, supporting urbanization and global economic and sustainable development.
