I believe in Major Surplus and Supply, probably in Torrance,  California.  
I got this maybe 12 years ago, and there was a note that came  with it that 
said that the mineral content had been assayed, and there was a  long list 
of contents.  It also said the guy was taking (don't remember if  it was 1/2 
teaspoon, or 1 teaspoon daily) it by mouth as a supplement.   Probably the 
1/2 tsp. is correct.

Food grade diatomaceous earth (about a teaspoon consumed daily) would  
supply minerals.  It also keeps bugs out of grain supplies and off your  
plants, 
not to mention out of your attic.  You can get it very cheaply in  very 
large quantities.

I  don't know if you are familiar with Joel Wallach who did the "Dead  
Doctors Don't Lie" tapes to get people into MLM colloidal minerals back  
in the mid '90's, but he maintained that given good food vitamins were  
not that critical since we can synthesize many in our tissues or gut  
with aid of bacteria (but not Vitamin C), but minerals are the basic  
building blocks that we must consume.   I don't know how to  replace 
colloidal minerals, perhaps by eating kelp if available, or  using 
glacial rock dust to grow our vegetables.
