APPENDIX A – INDUSTRY OVERVIEW Cobalt - Lithium There are three types of cobalt based battery technologies: • Lithium Cobalt Oxide (60% Co) predominantly used in mobile phones, tablets, laptops and cameras • Lithium Nickel Manganese Cobalt Oxide (15% Co) predominantly used in electric bikes, medical devices, electric vehicles and industrial applications • Lithium Nickle Cobalt Aluminium Oxide (9% Co) predominantly used in Tesla motor vehicles, medical devices and industrial and electric powertrain Cobalt based batteries continue to dominate the global supply with the technology supplying 68% of the global lithium ion battery market. Demand for lithium ion batteries to create energy storage solutions is increasing, with global storage expanding from 46 GWh in 2011 to over 100 GWh in 2015 representing a five year 16.7% CAGR. Additionally, ResearchInChina predict that between 2011 and 2020 the market is forecast to report a cumulative deficit of over 22,000t creating pricing incentives. As a result, ResearchInChina predict a price of US$22/lb to be achieved.

Global Demand Breakdown of Lithium Ion Batteries by Type - 2015 Global Lithium Ion Battery Market (GWh) 2011 - 2015

Copper Industry • BMI Research have raised their 2017 copper price forecast from US$5,150 per tonne to US$5,500 per tonne as solid Chinese demand growth and supply disruption concerns will keep prices elevated in the near term • Over a multi-year horizon, BMI Research expect copper prices to gradually improve as outlined in the adjacent table • World refined copper consumption is expected to outweigh production. China will be the biggest contributor to world consumption. ICSG expects world usage to increase by >1.5% year-on-year, mainly because apparent demand in China is expected to increase by around 1.5%, although underlying “real” demand growth in China is estimated by others at around 4%. Usage in the rest of the world is also expected to increase by 1.5%
