You have not given us a lot to go on with respect to which company, however part of the problem is that if you bought 30 yrs ago, that was at the absolute peak of a gold mania.
If you check the 30 yr gold chart you will see the price peaked in 1980 and did not recover till 2007.
Your shares must have looked pretty sick even 2 years ago!
I recently read a report commenting the time to buy junior gold shares is when every one else despises them and thinks you are a fool ( with 5 attached recomendations that averaged over 300% in 18 months)
