Opal?

I was around a site along plateau state, and my quest to site see other important area and minerals being mined in that area took me to this site. I was at first shock when I see these miners. I tried to questioned them and to my surprise I was shocked at the answer. OPAL BOULDER! One of the exclaimed. At this point I was forced to see exactly what they were calling opal Boulder. Believe me I saw a shock of my life when I noticed this material.

One question that I asked myself is.....can this be opal......

I kept watching closely until I saw this

Obviously this project is a prospecting to really confirm if they are working on opal truly....

Please wish them good luck
