How to Find Gold Veins Gold Deposits in Rock Formations

Most of the prospecting methods for finding gold that we discuss on this blog include panning for flakes and dust, metal detecting for nuggets. or large-scale mining. There is another, less common method of finding gold, however: searching for gold veins that exist as deposits in exposed rock formations above the ground (usually mixed with formations of quartz).

How to Test a Rock for Gold Sciencing

13/03/2018  Take a rock that contains gold in it – this process works best on quartz rocks – and set it inside a glass jar. Add white cooking vinegar to the jar, covering the entire rock and then some with the vinegar.

The geology of the Dolgellau Gold-belt

Mesothermal gold-quartz lodes are common throughout the Gold-belt, but have only produced significant gold at certain localities. The total recorded output of the Gold-belt is ca. 4 tonnes of gold, mostly being produced by two mines, Clogau and Gwynfynydd, in the late 1800s and early 1900s. Intermittent exploration and production have continued to the present day, with the last large-scale ...
