Why do you think copper outlook is poor? Most commentary I've seen suggests higher copper price in 2019. I appreciate the transparency @mineralised

This is from the December 2018 Resources and Energy Quarterly from the Office of the Chief Economist:

"As market fundamentals re-assert, copper prices are expected to rise to US$6,434 a tonne in 2019 and US$8,013 in 2020 (Figure 12.1). This would effectively bring prices back above the recent peak (at just over US$7,000 a tonne) of early 2018. Should market deficits persist, copper prices could approach the historical highs of 2011"
