Parys mountain has been mined for Copper since the bronze age period. Large scale copper mining was abandoned in the later 1890s due to increasing costs.
Since that time a number of companies have continued to explorer the possibility of reopening the mine.
The latest of these is Anglesey Mining PLC. In the 1980 they opened a new shaft and erected a head frame on the mountain to explore for "poly metalic ore". This is ore containing mainly Zinc and copper but with a small amount of silver and gold included in it.
The ore was raised and separated by new floatation techniques at an on site pilot plant. Since the 1980s the company has been involved in further exploration to define and secure the ore base and has been waiting for un upturn in world metal prices which would make a new mine an economic attraction.
In 2007 the company entered negotiations with Western Metals from Australia which could se further expansion and development of the testing and the eventually opening of a new ore mine with up to 150 jobs.
