WS04 - Potash Deposits: Exploration, Orebodies, Economics, and Global Setting

Date: September 16-17, 2017

Location: China University of Geosciences, Beijing (CUGB)

Presenters: Mark Arundell, Tabetha Stirrett, Roger Edgecombe

Food production needs to more than double by 2050 in order to feed our growing world. Potash, along with other fertilizers, will be a major component to increase farm productivity in the future. Twenty-first century mining and mineral exploration companies need to understand the tools to minimize the expense and increase the success of a potash exploration strategy.

"Mega" potash deposits are the result of the evaporation of seawater and crystallization of potassium salts. Deposits may only be a few to several tens of meters thick but tend to be laterally continuous—individual potash beds can be traced along strike for many kilometers. These "rock salt" deposits are a mixture of sylvite (KCl) and common salt (NaCl).

The workshop will cover the following topics:

  • Geology of many important potash deposits around the world, with a focus on Asian deposits.
  • How to explore for potash deposits and the various exploration techniques used, such as seismic, wireline geophysics, and the significance of rock mechanics and dissolution testing.
  • The differences between conventional and solution mining for potash.
  • Identifying minerals commonly associated with important potash deposits (rock samples).
  • Why companies report using the NI 43-101 or JORC guidelines.
  • How to differentiate between mineral resources and reserves and how to properly report them.
  • At a high level, understand the economics of a potash project—what makes a project financially feasible

Students will not exceed 20% of total participants.

Spectral sensing technologies can provide detailed mineralogical information throughout the mining life cycle, from exploration through to mine planning and operation. Reflectance spectroscopy can rapidly characterize mineral assemblages across dif ferent ore deposit styles, such as epithermal, porphyry, and skarn systems.

Building on a strong background in mineral spectroscopy theory, this workshop aims to improve skills for identifying the appropriate spectral sensing technologies for the exploration or mining challenge. Case studies of a variety of deposit styles will be presented and various visible, near-, shortwave, and thermal infrared spectral sensing applications will be discussed. Furthermore, solutions to information extraction, product generation, and integration with geochemical and other geoscience datasets will be explored. For this, hands-on case studies will be undertaken using The Spectral Geologist (TSG) software

WS08 - Fluids, Minerals, and Melts: Investigating Hydrothermal Processes Using Laser Ablation-ICP-MS Techniques

Date: September 17, 2017

Location: China University of Geosciences, Beijing (CUGB)

Presenter: Brian Rusk

Laser ablation-based microanalysis is rapidly revolutionizing our understanding of ore deposits by enabling precise trace element and isotopic analyses with high spatial resolution and high sensitivity. LA-ICP-MS trace element and isotopic analyses yield insight into a range of processes relevant to ore deposit formation, such as fluid, metal, and magma sources; fluid and magma compositional evolution; fluid-rock reaction pathways; ore and gangue mineral precipitation mechanisms; and metal partitioning among fluids, melts, and minerals. The purpose of this one-day workshop is to show how LA-ICP-MS can be applied to understanding ore deposit genesis and exploration. The workshop will include practical advice on conducting an LA-ICP-MS study along with examples, scenarios, and case studies to illustrate the usefulness of LA-ICP-MS to understanding ore deposit formation. Discussion will consider trace element and isotopic analysis of minerals, fluid inclusions, and melt inclusions. Lectures will detail instrumentation and application of LA-ICP-MS techniques to solving problems relevant to ore deposit genesis.

Presenter: Jean Cline

The Carlin-type gold deposits in northeastern Nevada, USA, comprise one of the most productive gold districts in the world, with gold production now in excess of 135 million ounces. Mining and research since discovery of the Carlin deposit in the 1960s have generated detailed descriptions of deposit geology, including recognition of features that are common to deposits across northern Nevada, though no single, widely acceptable genetic model has been developed. This two-day workshop will focus on (1) the geologic evolution of northeastern Nevada that produced an ideal geologic architecture for the deposits, (2) geologic processes in the late Eocene that were critical to deposit formation, (3) geologic models for deposit formation, and (4) the geology of Carlin-like deposits in Guizhou Province, China, including a comparison with the Nevada deposits. Presentations will include detailed descriptions of deposit geology and implications for exploration and research.

WS14 - Deformation Processes and Structural Analysis in Fracture-Controlled Hydrothermal Ore Systems

Date: September 21-22, 2017

Location: China University of Geosciences, Beijing (CUGB)

Presenter: Stephen F. Cox

The workshop is designed to provide exploration and mining geoscientists with a robust understanding of structural analysis and ore targeting in fracture-controlled hydrothermal ore systems, including orogenic gold and intrusion-related systems. Within the context of high fluid flux seismogenic systems, the workshop will examine how the formation of fracture-controlled flow systems and their structural styles are influenced by fluid pressure regimes, stress states, and fluid flow. We will explore the processes controlling why and where permeability enhancement and high fluid flux are localized in faults and examine how deformation processes influence the geometry of high fluid flux pathways and ore deposits formed within fault zones and fracture networks. Lectures will be supplemented by simple practical exercises that will further develop participants' expertise in structural analysis and ore targeting.

Students will not exceed 20% of total participants.
