i own 100 shares of a company called microcopper. i believe the shares were purchased in the mid to late 60's

i am not sure if the company was bought by another company. if it is still in business. or any other details other than, ive been lead to believe that the company also stockpiled uranium back in the 1960's. has anybody ever heard of this company? who are they currently owned by? how do i find out if this stock is worth anything? did they merge with another company? i know nothing about stocks or how to research them.
