Attempting to blow up the Marmite mines may not be such a good idea...
These mines are owned and worked by the "Marmites", proud and ferocious beings that would have no qualms in taking any ill-doers prisoner, forcing them to work with them in the mines, living on a diet of bread and the local delicacy..
So DJM, I would love to see you try...
Of course I would visit you now and then, try to smuggle in a bar of Snickers or something...
