Epithermal Au-Ag and Porphyry Cu-Au Exploration

Greg Corbett and Stuart Hayward are presenting their informative and well regarded epithermal Au-Ag and porphyry Cu-Au exploration short course in Sydney this December.

Two days of PowerPoint lectures (December 4 and 5) focus upon mineral exploration for epithermal and porphyry ore deposits derived from Dr Corbett’s 40 years field experience, including earlier short courses provided with the late Terry Leach from the early 1990’s. Exploration and mining examples from over 40 countries are used to delineate the characteristics of different epithermal and porphyry ore types, and controls to mineralisation, using tools such as alteration, structure and breccias. The exploration implications are considered throughout and a final section considers geological features recognised in exploration marginal to ore bodies. Participants will be provided with a current draft to the new short course notes. Drafts of the first few chapters are available here.  The lectures will be held at the York Club, 99 York St Sydney, with lunch, morning and afternoon teas provided. 

A practical exercise will be held W B Clarke Geoscience Centre, Londonderry December 6, using selected diamond drill core referred to in the lectures and a set of teaching specimens to provide hands on training in ore and alteration mineralogy and the use of geological models. It will be run by Corbett and Stuart Hayward, who has over 30 years experience in epithermal-porphyry ore deposit exploration and mining. A return bus from the city and lunch provided.

Prices include lunch, morning and afternoon teas and transport to and from Londonderry.

  • Students $150 + GST, but if you need assistance contact greg@corbettgeology.com
  • Unemployed geologists $400 + GST
  • Employed geologists $1500 + GST

Minimum of 20 participants required and limited to a maximum of 40.  For registration details visit www.corbettgeology.com/services/

Two new events from Geoscientists Symposia

Geophysics for the Mineral Exploration Geoscientist

Date: 11-13 December 2017

Venue: Tawarri Reception Centre, Dalkeith WA

Presenter : Mike Dentith

This innovative training course uses applied learning techniques and real-world mineral exploration scenarios to train participants in the key principles of interpreting geophysical data sets, without the need for complex mathematics and physics.
This course teaches participants to integrate geological and geophysical methods to optimise mineral exploration.
With more than 25 years experience in teaching, research and consulting in mineral exploration geophysics, Prof Mike Dentith is co-author of the award winning textbook, Geophysics for the Mineral Exploration Geoscientist, on which this course is based. He has run professional courses for industry, government and professional societies in Australia, South America, Asia and Africa.

Updated: The long term outlook for Australian gold

Long-term forecast of Australia’s mineral production and revenue The outlook for gold: 2017-2057

Report by MinEx Consulting: October 2017

Under the combined support and sponsorship of six government agencies (both State and Federal), three research organisations and three industry groups, including AIG, a landmark report has been published by MinEx Consulting looking at the forty-year outlook for the Australian gold industry. It forecasts the likely number of mines, production, revenues and employment out to 2057 for this vital sector of Australia’s economy.

In the past, most industry studies rarely look beyond ten years. The report’s author, Richard Schodde, says that “there are two good reasons for this; Firstly; the future is highly uncertain – and any single-line forecast is almost certain to be wrong. Secondly; most of these studies only looked at existing mines and possible new projects. This is fine for short- to medium-term forecasts but it ignores the important contribution of new discoveries for mine production in the longer-term.”

It goes without saying that every mine has a finite life (and will eventually close down); it also equally true that all mines were once a gleam in the eye of a geologist (i.e. it took someone to find them). Leaving out the discovery story results in an incomplete view on the long-term future of the mining industry.

As discussed below, nurturing exploration success is critical for ensuring the long-term sustainability of the mining industry.

MinEx Consulting’s approach to the task was via the following eight-step process:

  1. Embracing uncertainty and using a Monte Carlo approach to assess 1000 different possible scenarios of the future. This included generating a series of commodity price cycles that reflect what the industry has experienced in the past.
  2. Estimating future production from existing mines, adjusted for changes in the gold price, variability in operating performance and possible mine-life extensions.
  3. Assessing whether the future gold price scenario is sufficiently high enough to trigger the development of new mines on known projects.
  4. Using the price scenarios to predict likely future exploration expenditures. And from this,
  5. Estimating the likely number, size and quality of discoveries made over time.
  6. Determining the likelihood that a given discovery will be developed and, if so, incorporating a time-delay between discovery and development.
  7. Developing a model to estimate the likely production rate and mine life for these discoveries. From this, estimating their likely timing and contribution to future revenues and employment.
  8. Integrating together the results for existing mines, new projects and exploration success.

The report will be officially released next Monday, 16th October, 2017.

A media release outlining the study objectives and process is available here.  The study report is available here.
