New sources of tin mine supply
Contents
1 Costly alluvial production, competitive hard rock mines?
2 Decline in Asia & Americas, rise in Australia, Africa & Europe?
3 Less primary tin, dependence on other riches?
4 No more low capex-high opex, now high capex-low opex?
5 Conclusions: investment in new tin mine supply is required!

Underground mine is a theoretical primary tin, underground mine in Australia, producing 7,500 tonnes of tin per year, with a processing recovery of 75%.
Open pit mine is a theoretical primary tin, open pit mine in Australia, producing 7,500 tonnes of tin per year, with a processing recovery of 75%.
Alluvial mine is a theoretical mine in Indonesia, producing 7,500 tonnes of tin per year, from a team of gravel pumps, with a 100% recovery.

Rankings based on Greenfields Research’s proprietary mining political risk ranking system. The ranking system correlates economic data sets
that cover most of the world’s countries (such as the Transparency International Corruption Index, the World Bank Doing Business dataset and
GDP/land area) with well known mining industry political risk surveys, including the Fraser Institute, Behre Dolbear and ResourceStocks, to get
a system which ranks all countries by their suitability for mining, not just those in the mining industry surveys.

New sources of tin mine supply
Conclusion
1 Alluvial tin supply falling to be replaced by hard rock mining.
2 Declining Asian mining, opportunities elsewhere in the world.
3 Increasing reliance on by-products as grades decline.
4 Future supply will have much higher capex, but lower opex.
5 New mines have to be lower cost than marginal alluvial mines.
