Additional analysis may also reveal more rare species or possibly new ones from this occurence. A similar, but less rich occurence of silver and cobalt is found at Hilderston in the Bathgate Hills, near Edinburgh. Here very small amounts of native silver is found with skutterudite , a cobalt arsenide and other species - often in massive barite. Several other very small finds of native silver in Scotland include localities situated on the Clyde Plateau Lavas of Carboniferous age around Glasgow. At both localities, silver occurs both as very small, microscopic wires and as crystals, the latter often in complex forms and, quite regularly, is associated with native copper .
Native silver is found only in very insignificant amounts in Scotland.
Galena found in the Highlands region is also normally rich in silver content. The Mineralogical Record - vol. The Alva Silver Mine, Silver Glen, Alva, Clackmannan, Scotland. Secondary Mineralogy of the Clyde Plateau Lavas, Scotland.
