Increasingly, gold deposits are becoming more difficult to find. They are lower grade, challenging metallurgy, deeper underground, more difficult to develop and located in geographies that present logistical, development and operating challenges.

In competition to these trends, Newcrest has a strong history of growth over the past 20 years, obtaining value from previously marginal, difficult ore bodies. It has developed mining and ore processing technology for the efficient extraction of copper as concentrate, gold as bullion and gold in copper concentrate. Examples include Cadia Hill, Ridgeway, Telfer, Cadia East and Wafi-Golpu.

An important element of Newcrest’s strategy is thus the adoption, adaption and development of innovative underground mining techniques and metallurgical processes, including:

  • innovative geo-metallurgy knowledge approaches
  • adapting more continuous underground and pit systems
  • technology to facilitate early waste rejection to avoid high energy processing downstream
  • technology to lower energy required for mineral processing.

Newcrest’s ‘Future mine’ vision is to utilise technology, along with continuous improvement techniques and step change methodology, to significantly reduce operating costs across its portfolio and increase production reliability.
