Can anyone identify this mineral?

I was out hiking and I found an area with a bunch of these stone's, you chip away the white and it looks like opal but I don't think its opal, does anyone know what it is and is it worth going back to get more? Much thanks...

Chalcedony with what appears to be some sandrox *pretty sure I spelt it wrong, someone will set me right* in the brown areas. Certain formations of this material can yield fire agate.

Yeah, what DDancer said ^^

my first impression was potch Mexican opal

I agree with DDancer and stdenis jd, looks just like fire agate I have seen from California.
