Sensitivity analysis demonstrates the project economics remain robust within most
Project only becomes uneconomic at the combination of the highest exchange rate and lowest commodity price assumptions. This combination is considered relatively unlikely and would also make most operating tin producers uneconomic.

Tin supply tightening as the largest producers, China and Indonesia, cut production in response to low prices Mine development queue is limited – only one new mine developed (Bisie in DRC) in the last 20 years and no significant exploration occurring Demand for tin weaker in 2019 due to declining semi-conductor shipments and lower auto production – price expected to rebound in 2020 Longer-term outlook is strong with new uses in the electronic and energy storage sectors to drive above trend demand growth post 2022

“Shanghai Metals Markets (SMM) expect tin prices to rebound above US$20,000/t by the end of 2019 as tight ore availability and maintenance-caused production cuts at China’s largest tin producer, Yunnan Tin, will lead to a sharp supply decline” according to SMM’s senior tin analyst presenting at the 2019 China Tin Summit on 6 Nov 2019 “China’s refined tin production has reduced by ~6% ytd in 2019” (SMM) “Significant reductions in China’s imports of tin
contributed to the current tight tin supply in China” (ITA) “China domestic ore production is expected to fall by ~5,000 tonnes (~6% YoY), helping to keep tin prices in the US$ 20,000 - 20,500/tonne range in 2020, while demand is likely to increase as the US and China head towards a partial unwinding of trade tariffs” (SMM) ~15% of the worlds tin production is currently

Tin ranked as the metal best placed to benefit from new technologies Tin use in electrical and energy storage applications is emerging and could be potentially disruptive New uses of tin could have a major impact on market size
24
Investment in the best tin project in Australia – highest grade undeveloped tin project in Australia and second highest globally Low cost investment – market capitalization significantly undervalues Stellar’s tin assets Heemskirk Scoping Study completed in October ‘19 demonstrates the project has attractive and robust economics Potential for early production from Razorback satellite deposit Significant exploration potential – both laterally and at depth in all Heemskirk deposits and within large Exploration Licence package Opportunity to invest in the next Rension Tin Tin is emerging as an energy metal – second generation battery raw material demand to drive opportunities for tin and higher tin prices
