OP: follow this advice.There is no need to open the tin (you said he is afraid). He can bring the tin as is and right away to a parish and give it to the priest, informing him of its contents. It is important to properly handle the tin (purify the tin of particles), and the priest will do all that.
It would not be correct to wait until Saturday confession to handle this. This should be handled right away.
