On this chart they seem to have global reserves of hafnium at 1, 124 tonnes.

Typically, zirconium and hafnium are contained in zircon at a ratio of about 50 to 1.

You will note that there are no statistics for world production of hafnium.

Using hafnium insulators, Intel has built prototype chips that are 45 nanometers wide and run Windows, Mac OS X and Linux software.
Intel's new insulator replaces silicon dioxide with a metallic alloy called hafnium.
For metals such as hafnium and indium, recycling is the only way to extend the lifetime of critical sectors of the electronics industry.
FORBES: Recycling Scrap Rare Metals Vital to Future Technologies
In 96 tiny wells robotic arms mixed variations of molecules containing nitrogen, oxygen and sulphur with metals such as zirconium, titanium and hafnium.
FORBES: Upstart Symyx is shaking up the stodgy chemicals industry.
This alloy isn't new--it's been used as a neutron absorber in nuclear power plants--but hafnium's use as a chip insulator required a fabrication breakthrough.
The first they dealt with by coating the top of the device with oxides of hafnium, molybdenum and titanium, in layers about 100 nanometres thick.
And further that hafnium is going to run out in 2017.
