According to maps, Tommy's Show pegmatite is in the vicinity of the Millar's Workings location, with the Anster, Horizontal and Easy pegmatites nearby. Mindat map approximate.

The pegmatite is coarse grained, trending west north-west for 110 metres, averaging 2.5 metres wide, dipping 45 degrees south. The pegmatite penetrates schist, with deeply weathered clayey soil in the Footwall. The source states the pegmatite contains quartz 'bungs' (?), and country rock schist sections. There is a second pegmatite 35 metres to the north, as a faulted eastern section of the main pegmatite.
