Tuff,
What you have linked to is essentially a dietary supplement. The concentrations of the Cu are far too small to have any effect on the thermal properties.
According to the Argonne laboratories site, the reason their nanofluids are so successful is much of the heat transfer occurs at the fluid surface, ie interfaces with other objects. I don't quite understand this, whether it means conduction through the liquid, of specific heat capacity, I'm not sure. However, they attribute the increases in thermal conductivity to increased surface area.
If you look at the electron micrographs on their site, you can see a dense dispersio of these particles which would indeed increase the surface area.
If it is the case that these particles work by increasing the suface area, then the copper mineral water you have suggested would offer no benefit at all. The Cu is in solution and has no "surface".
Another suggestion is that a "proportion" of the liquid would have higher thermal conductivity or specific heat capacity. Both of these factors might improve the cooling ability. However, in order to work out the new values, you would have 90/1000000 * the values of Cu plus 999910/1000000 * times the values of Water.
In both cases, you are looking at effectively zero contribution from the Cu.
Hope this helps
