Tridge800,
There are so many different possibilities involving the area in your pictures and all of them spell Adventure in the making. The quartz, the iron pyrite, the coloration's, the fact your location is near/on/above or in the vicinity of an historical working gold mine all show signs of possibilities afoot. As indicated by others take some samples of the quartz in various places (wear safety glasses and gloves and keep little children protected from flying rock chips or chisels) along with some of the nearby dirt which could have rotted off of the quartz deposit and see what you can find in all of this. Also you've a detector that will find gold, use it slowly in passing over the ground around there and listen closely. Do you have a test sample to use with your detector, a small piece of lead or gold would also work? They come in handy out in the field just to get oneself back in tune to what they need to listen for.
Good Luck and please keep us updated........63bkpkr
