Spectral reading and analysis of a Pegmatite I found

My son and I found an outcropping of Pegmatite in Northern Idaho years ago. We sent in a rock to Nasa when they did Kids send us your rocks in 2006ish. I always thought I had an analysis of the Pegmatite but in re-reading the info of low Mica I realized we might have not sent a good Peg specimen. Just a nearby rock. The Pegmatite has extensive Mica as you can see in the picture. I showed a Geologist years ago he said I should go back there and search for crystals. I might do that this summer. I live in Tampa for the winters. So now I'm curious as to the mineral makeup of the Pegmatite and any content that would glean a crystal type to look for. Not sure if its feasible or affordable for me to have a new analysis. Any thoughts are appreciated. John Pongrac
