They are unique looking pebbles and have a watery smooth texture, despite their often dull fine grained skin colour. They are formed as ring growths of silica, so if you think of their formation, their appearance will start to talk to you. Pebbles are smoothed by erosion and are made of rock material that is rarely coloured uniformly dull. Agates may be eroded but they are formed by growth. Think of looking for a uniformly coated egg of lighter material. Few boulders or cobbles exhibit this colour and characteristic. Gold in a rock and you don't know where you found it? Tsk tsk. The true rock collector always labels rocks with white out and india ink and takes notes with GPS and time. Taking notes is time consuming but often necessary and should accompany pictures too. Finding gold in quartz is not that common, and it could be an interesting find indeed. There is a place east of Atlin called Discovery, which has plentiful gold in gravels. Mt. Freegold has good gold too. If BC relaxed their laws concerning placer yardage from the ridiculously low right now, to a bearable amount, some of these areas could be reworked with higher recovery methods. The sluice method of the 80's and earlier lost a lot of the fine gold. I would consider using cyclones, power rockers, or centrifuges and flotation these days and treating my con by several different leach methods and extraction methods. (Knelsons, camel wheel, induction tables and cyanide or nitrate leaching) It might double recovery or better. A lot of gold was lost in treating sluice cons unless mercury was used and no one wants to use mercury today because of pollution and hazard.
