Please help as I am unable to find the answer.

I would like to try using Isomalt for the first time.

Unfortunately I do not understand if I have to purchase a mold made of special material for the isomalt or can I use any silicone mold? I certainly do not want to destroy the few silicone molds I have at this time by experimenting.

Thanks for the help and advice I know CC members will give.

You can use Isomalt with any food grade silicone molds. For the most part, those molds are safe up to 400F. You won't heat up your Isomalt higher than around 315F.
