Overview

Where the physical geology module identifies rocks in the hand, this one looks through them. It covers crystal chemistry and the silicate structures, systematic mineralogy of the groups that matter in exploration, and optical mineralogy under the petrographic microscope. Thin section work takes the second half, building to interpretation: texture and mineral assemblage as a record of the conditions a rock formed under, and the alteration that points toward ore.

It runs 7 times over the published calendar, in 6 cities and live online. Every date is the same programme with the same content and the same certificate.

What you will be able to do

  • Relate crystal structure and chemistry to mineral properties.
  • Identify rock forming and ore related minerals systematically.
  • Use a petrographic microscope and the standard optical properties.
  • Describe a thin section in correct terms.
  • Interpret texture and assemblage as a record of conditions.

Who should attend

Exploration and mine geologists, laboratory and core shed staff, geometallurgists, and geoscience students.

Is the level right for you?

This is an intermediate level programme. It assumes you are working in or moving into the area it covers, and it is built around your own material rather than a case study. If you are unsure, ask an advisor before registering rather than after.

How it is taught

Short input, then work. Across 5 days of roughly 6 teaching hours each, the balance sits deliberately with the second: a programme where the trainer talks for six hours produces notes rather than capability.

  • Your own material

    Exercises run on situations delegates bring, not on a case study written for a different organisation in a different decade.

  • A capped cohort

    Small enough that everybody is asked something. Executive programmes are capped tighter still.

  • Practice under scrutiny

    The difficult conversation, the challenged assumption, the decision defended out loud. Judgement is not built by watching.

  • Something to take back

    Each day ends with a thing you can use on Monday rather than a slide deck you will not reopen.

The programme, day by day

Day 1Crystal chemistry

Crystal chemistry

  • Bonding, structure and the silicate classes
  • Solid solution and polymorphism
  • Physical properties from structure
Day 2Systematic mineralogy

Systematic mineralogy

  • Silicates, oxides, sulphides and carbonates
  • Accessory and indicator minerals
  • Ore minerals and their associations
Day 3Optical mineralogy

Optical mineralogy

  • Plane and crossed polarised light
  • Relief, birefringence, extinction and pleochroism
  • Using the microscope properly
Day 4Thin sections

Thin sections

  • Preparation and its artefacts
  • Systematic description
  • Modal estimation
Day 5Interpretation

Interpretation

  • Texture as a record of history
  • Assemblages and conditions of formation
  • Alteration mineralogy and vectors to ore

What you leave with

  • Completed thin section descriptions.
  • An optical identification scheme you can work from.
  • An alteration assemblage interpretation.

The certificate

A GATI certificate recording what you attended, issued after the programme has run and attendance has been taken. Attending at least 80 per cent of the days earns a certificate of completion; attending less earns a certificate of attendance stating exactly what was attended.

Every certificate carries a code that anybody can check against GATI's own record, which is what makes it worth holding. It records participation. This site will not imply one it does not have.

Questions

Who is MINING & MINERALS EXPLORATION TECHNOLOGY (Mineralogy and Petrology) for?
Exploration and mine geologists, laboratory and core shed staff, geometallurgists, and geoscience students. It runs at intermediate level within Mining Engineering, so it assumes you are working in or moving into that area rather than meeting it for the first time. If you are unsure whether the level fits, ask an advisor before registering rather than after.
How long is it, and what does a day look like?
5 days, running to roughly 6 teaching hours a day. Sessions are built around your own material rather than a case study, so a day alternates between short input and working on something you brought. The full outline is on this page, day by day.
What does it cost, and what is included?
The next published date is Live online at US$995 per delegate. The fee covers tuition, all programme materials and the certificate. Travel, accommodation and visas are arranged by the delegate. Fees vary by city, and every published date shows its own.
Can it be delivered for my organisation only?
Yes. Any published programme can run as a private cohort, on dates that suit you, in your city or online, built around your own material. That is a different conversation from registering an individual, and it starts with what capability you are trying to build rather than with a course title.
What certificate do I get?
A GATI certificate recording what you attended, issued after the programme has run and attendance has been taken. Attending at least 80 per cent of the days earns a certificate of completion; attending less earns a certificate of attendance stating exactly what was attended. Every certificate carries a code that anybody can check against GATI's own record.
Is the online version the same programme?
Yes. The same faculty, the same material, the same cohort cap and the same certificate. It is not a recording and it is not a reduced version. It exists because travel budgets and visa timelines rule people out of a room they should be in. The classroom version runs in Port Louis, Nairobi, Windhoek, Dubai.

Want to take this further?

Register on a published date, or tell an advisor what you need and they will come back with something specific rather than a brochure.
