CODES, GHD AND MRT PRESENT… ADVANCES IN GEO-LOGGING

DATE: 8 to 11 September, 2014
VENUE: Mineral Resources Tasmania (MRT) facilities, Hobart.
WHO SHOULD ATTEND: Exploration geologists, mine geologists, geotechnical staff, exploration managers, and other mining industry professionals.
This intensive four-day program will provide attendees with a thorough understanding of the latest logging techniques, and how they can be used to improve geo-investigation, planning, and reduce risk, costs and uncertainty within the mining environment. The course is designed and presented by two leaders in their fields – CODES and GHD Pty Ltd. – with support and facilities being provided by MRT.

ASEG NSW Branch Up-Coming Meetings – Wednesday May and August

May 2014: Integrating Rock magnetic studies with Automated techniques to identify prospective Nickel Sulphide Systems in the Musgrave Ranges, SA. – by Dean Hillan (with an Introduction by James Austin)
August 2014: Advantages and Limitations of Magnetic and Gravity data for Mineral Exploration Undercover – James Austin and Dean Hillan
Abstract: Many classes of ore deposits (e.g., Porphyry, IOCG and Magmatic Nickel Sulphide deposits) have characteristic magnetic and or gravity and or EM signatures. However, recognition of these signatures is more difficult when deposits are undercover. Simplified rock property models were constructed of different deposit types. The physical parameters (e.g., depth and orientation) and rock property values (e.g., susceptibility, remanence and density contrast) and the effects of weathering and oxidation were varied to reflect different exploration scenarios. The resulting gravity and magnetic anomalies are presented to illustrate the advantages and limitations of magnetic and gravity methods for exploration undercover.

PhD Project on offer from EGRU – FSE porphyry deposit, Philippines

Jeff Hedenquist, Antonio Arribas and Zhaoshan Chan will supervise a PhD project on the Far Southeast porphyry deposit (FSE, Philippines) at EGRU, James Cook University, Australia. If you are be interested in this PhD position, please open the link here or help pass on the information.

FSE is the type locality that proved the genetic link between porphyry and high-sulfidation epithermal deposits (Arribas et al., 1995; Mancano and Campbell, 1995; Hedenquist et al., 1998). It is also the site where mineral vectors in lithocaps that indicate proximity to the porphyry roots were discovered (Chang et al., 2011). Recently, Gold Fields has carried out >100km of drilling at Far Southeast, providing a 3-dimensional picture of this system over 2 vertical km to -700 m elevation, 400 m below the ore body. This provides arguably a unique opportunity to examine a porphyry system from the roots of the porphyry, through the main porphyry body, up to the mineralized lithocap.
