A most Frustating Stock

Have held these for 10 years and have quite a few. About square ,which is obviously a loss with no income from them. Was talked into them by a broker and while result won't change my life I would prefer a good result. I do not follow them all that closely but where they are really confuses me. When you do get info from them you look at things like the annual report and see page after page of glossy photos of all the infrastructure that is built or being built. Don't know where to get the answer easily , but it must be a massive amount that has been spent to date . For what?
