Innovation……….
• Invention vs innovation
• Many kinds of innovation: - IR, WH&S, finance, procurement, management, environmental, social, exploration, mining, minproc, extraction met.
• Innovation is not optional

Why did Delprat succeed ?
6 Tim Napier-Munn, JKMRC/JKTech
1. A crisis – difficulty in processing the Broken Hill sulfides.
2. Competition between the BH mines.
3. Collaboration with others.
4. A skilled technologist.
5. An entrepreneurial nature.
6. A GM’s power.

• Main drivers are opex/capex, and competition.
• Enabling technologies important (eg materials, CAD).
• Can we increase scale indefinitely? Or are we running out of options?

Barriers to Innovation VCI Report 2016
55 Tim Napier-Munn, JKMRC/JKTech
• Paul Muller (MD, Consolidated Minerals) “Short termism is the biggest problem and is more so in difficult times. How do you encourage the ability to think medium to long term? It comes down to quality of leadership..”
• Andrew Harding (formerly Rio Tinto CEO Iron Ore) “It becomes harder to find support to do something big [in innovation] when the sector is at the bottom of the investment cycle”
• VCI Report “Innovation State of Play” 2016 “Investor perspectives of mining need to shift from innovation being associated with risk to lack of innovation being associated with risk to sustainable returns. CEOs acknowledged that miners need to better educate investors…”

Barriers to Innovation
Unnecessary protection of IP

“The way industry deals with IP is seen as a key barrier, as IP
‘hoarding’ directly impedes the advance of innovative practices”
CEEC Industry Workshop, 2012

The prize goes to those who use the technology
the best, not to those who own the IP

We need to, and can, innovate better

• Preserve the corporate memory
• Manage FIFO rosters to improve continuity
• Strengthen the innovation links
• Take a longer view; less short-termism
• Rational, long-term management strategies for dealing with technology
• Be more relaxed about some IP
• Tear down the silos
