mixing 2 Pantone colors in AI (for print), is it possible?

Hi

I'm working on a logo for a client for use in business cards, letterheads, etc. It's starting to look nice, but a little plain since it's limited to two colors. They're called PMS colors in Dutch, i don't know about yall since that means something else in English
Anyway.. so far i've worked with Pantone Yellow CVC and Pantone 301 CVC (dark blue).

Now for the question: theoretically, it should be possible to mix these so you'd end up with a range of shades of green. But i can't seem to figure out how to mix PMS colors in Illustrator. Sure, you can overlap the shapes and "merge" but that turns the green into a CMYK color... that's no good because we're not printing it in CMYK but in two Pantone colors.
Still, it would be ****ing retarded if you can't do that. Two people have told me so far that it can't be done, but they're no Illustrator experts either. I can't be the only person who want to do this and it is possible with layout software like QuarkXpress so it SHOULD be possible in Illustrator.
I COULD replace the dark blue with cyan and work in CMYK since there's no magenta and black in it anyway so it would still finally be two colors, but cyan doesn't make a nice solid color... so i don't want that. Of course then we could just use Pantone 301 instead of the cyan, but then there's no telling what it's going to look like.

Does anybody know a solution to this?

Thanks in advance.

Sincerely,
AAAAARRGH

overprinting pms colors in illustrator

2 ways of achieving this:

1. In Illustrator 9 or later, take the shape that is on top and set it on "Multiply" in the Transparency panel (Windows>Transparency, Multiply 100%)

2. In older versions of Illustrator, there is another way of doing this. Select the topmost shape and, in the Attributes panel, click on Overprint Fill or Overprint Stroke (or both) (Window>Attributes).
You can also view the effects of this printing attribute by using View>Overprint Preview (shft-option-cmd-Y).

w00t thank you so much

The first method doesn't work.
The color seperated print spat out four sheets (CMYK) and two blank ones (where the Pantone colors were supposed to be)

Blending options such as "multiply" don't work when you're going to print something using spot colors (you can't multiply one ink with another).
But even with normal blending it won't do because we we always deliver version 8 .eps files to the pre-press bureau, for compatibility reasons. And as i just tested, version 8 of .eps doesn't support transparency properly, it either disregards transparency or flattens all paths into CMYK.

I'm going to try the other method tomorrow. The version 8 .eps i just made does seem to act right

EDIT:

That second method works
Although i decided i'm not gonna use it in this particular logo lol... but now i do know how if i ever want to. Thanks again.
