Introduction The Scottish
Highlands is famous for its pure water - an essential
ingredient in making Scotland's national and world-famous
drink - whisky (from
the Scottish Gaelic "uisgebaugh" meaning "
Water of Life" ). A Scottish Gold Rush In the 19th
century, around 1860, there was a "gold-rush"
in the northern Highlands to a locality in the county of
Sutherland - though, as can often be the case, there was
more rush than gold. Nuggets with
attached matrix can be found, but well-crystallized gold
on matrix, is much less common.
Each of
the ten bottles above represents a different stream -
spanning Leadhills (Lanarkshire) in the south, Gold Panning in Scotland - A Basic Guide The following information and hints on gold-panning have been graciosly made available for publication by an anonymous gold-panner from Scotland, with great experience and, as the photographs testify, with a great deal of success.
At Wanlockhead,
one can learn and practice the art of panning and pan for
the precious metal itself, as small nuggets and flecks,
in the surrounding burns... Wanlockhead has been host to
panning contests, including the World Gold Panning
Championships and the mace of the new Scottish Parliament
is gilded with Leadhills gold.

NUGGETS Scottish Gold-Mining |
Gold is found in situ as micro flecks in quartz veins over a fairly large area of the Highlands. The main occurence, around the Highland Boundary Fault - which forms the southern border of the Highlands region - is centred around the Tyndrum & Aberfeldy area (Argyll & Perthshire). Scotland's first gold mine was planned to open in this area a few years ago. However, due to economic factors, the operation has been cancelled indefinitely. Scotland's most
famous mineral deposit at Leadhills and Wanlockhead started out mining for gold. The
eventual decline in the extraction of this metal turned
attentions to the rich lead ores that also occured in the
area. Its lead deposit has since given it world fame -
particularly as a result of the rare and common, lead
mineral species found there. As the gold gets
eroded out of its matrix, it eventually drops into the
nearest burn as nuggets, great or small. |

In the last couple of decades, waste dumps were scoured on a small and forgotten occurence of cobalt and silver ore that was worked at the start of the 18th century (around 1715). On the edge of the Ochil Hills, near Alva, in the "wee county", Clackmannan, it is the richest deposit of silver in the United Kingdom. When the small
dumps of the site were scoured, they revealed superb,
small specimens of skeletal and arborescent groups of
native silver crystals, some associated
with accessory erythrite or with crystalline masses of
the rare species, clinosafflorite, a
cobalt arsenide mineral. The common and predominant habit
of the silver is as dendrites with 90° branches. Other
habits occur, but are rarer. Specimens are of great
beauty and fine quality. Though
crystallized specimens are generally small, only up to
around 5mms, a very few, larger specimens were uncovered.
The Hunterian Museum of Glasgow University has one such
specimen extracted from the time Analysis has revealed the silver is rich in mercury, containing around 10-15% of this element. Alva silver therefore approaches amalgam in its chemical constitution rather than the "kongsbergite" variety of silver, which is also mercury-rich. Additional analysis may also reveal more rare species or possibly new ones from this occurence. The Alva silver
mine is now barren: a later extraction has since cleaned
out the deposit A full account of
the extraordinary history of the Alva Silver Mine is
related in the recently published book entitled, |

Other Scottish Silver Occurences |
A
similar, but less rich occurence of silver and cobalt is
found at Hilderston in the Bathgate Hills, near
Edinburgh. Several other very small finds of native silver in Scotland include localities situated on the Clyde Plateau Lavas of Carboniferous age around Glasgow. Boyleston Quarry near Barrhead (Renfrewshire) and Loanhead Quarry, near Beith (Ayrshire) are two examples of such occurences. 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. In
the past, silver was extracted |
