Miner (The Bride of Peladon)

From Tardis Wiki, the free Doctor Who reference

A Peladonian miner in the 41st century was the son of a foreman on Peladon. He had discovered a piece of pure trisilicate ore, while he was digging, according to Elkin, in the wrong location. He showed the trisilicate to his father to prove him wrong. Shortly afterwards, he was killed by Sekhmet, who had been entombed in the trisilicate as a prison. (AUDIO: The Bride of Peladon)
