1950-60s – invention of tantalum
capacitor, adoption partly driven
by US space program
1980 price spike to panic buying
by consumers, due to worries
about mine supply.
2000 price spike a combination
of surging demand from mobile
phones and an opaque market,
partly fuelled by war in the
Congo.
Current spike partly relates to
this “conflict minerals issue.

14. Conclusions on tantalum supply
Tantalum demand driven by growing electronics industry
Opaque market, subject to spikes
Past demand destruction and structural supply changes
Recent structural change: Congolese conflict tin at the expense of
Australian & Canadian hard rock supply
Dodd-Frank Conflict Minerals legislation has led to a de-facto embargo on
Congolese tantalum
Is another structural supply change imminent?
• Conflict free Congolese tantalum, integrated with consumers?
• Resurgence of Australian & Canadian hard rock supply through globally
integrated companies?
• Price insensitive, low cost by-product niobium production?
• Other mine projects in North Africa, Russia China?
• Opening up of new exploration “search space”?
The actions of the small number of actors in the industry will have a big
affect on which of these outcomes occurs.

industry creates a “prisoners dilemma”.

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.

44. Conclusions on tin mine supply
Tin demand driven by growing electronics industry
Market is currently supply driven, with falling production from key regions
Tin industry has a history of alluvial mining “booms & busts”
Dodd-Frank Conflict Minerals legislation has also led to a de-facto
embargo on Congolese tin
The major San Rafael mine in Peru is due for closure
Is another structural supply change imminent?
• Resurgence of Australian & European hard rock supply?
• Conflict free Congolese tin, integrated with consumers?
• More complex by-product related industry?
• New production from opaque, but known tin regions (Myanmar, Brazil, China)?
• Opening up of new exploration “search space”?
The large number of unknowns in this industry mean it is difficult to
predict exactly which future will prevail.

47. Comparing tin and tantalum
Tin and tantalum demand driven by growing electronics industry
Tin and tantalum industries have histories of “booms & busts” relating to
major supply and demand changes
Both industries seem to be on the verge of a structural supply change
Dodd-Frank Conflict Minerals legislation has also led to a de-facto
embargo on Congolese tantalum – also an issue in tin
Costs and formalisation of alluvial and artisanal an issue in both industries
Structural supply changes could come from:
• Resurgence of Australian & European hard rock supply?
• Conflict free Congolese minerals, integrated with consumers?
• More complex by-product related industries?
• New production from opaque, but known regions (Myanmar, Brazil, China, CIS)?
• Opening up of new exploration “search space”?
Or will the supply side continue on as it is currently?
Both industries seem very difficult to predict
