The West Lothian area has been extensively mined for a variety of minerals and metals, so much that parts of the county appear to be hollow!
Scotgold Resources plans to extract more then £50m worth of gold and silver from a hillside near Tyndrum.
It has been 500 years since gold was successfully mined in Scotland, but the high price of precious metals now makes the work cost-effective.
Scotgold Resources said the mine was expected to produce about 20,000 ounces of gold and 80,000 ounces of silver a year.
About 5,000 ounces of the gold will be extracted as unrefined bars and identifiable as "Scottish gold" - which can attract a premium because of its scarcity.
Forestry work has been ongoing since the storms in January, and some areas are cordoned off.
Please respect the notices and do not enter areas which have been restricted.
Thanks to the Beecraigs Country Park Rangers for allowing these caches to be placed.
