I haven't managed to find any published radio metric age on it yet, but it is mapped as being Quaternary, in which case it is part of the alkaline rift volcanic province that includes Deception Island.
It's appearance seems to have a lot in common with Staffa, although I've never been there.

@PoLaRobs@fediscience.org I should have heard of Edinburgh Hill - there are at least three specimens from there in the Hunterian museum collections in Glasgow, which I spent 30 years curating! https://www.gla.ac.uk/collections/#/results?q=South+shetland&gn=All+Fields These were collected by Glasgow geologist David Ferguson, who made a lot of trips to the Antarctic, sponsored by Christian Salvasen Ltd before WW1. He made the 1st geological map of South Georgia too. More here if you're interested: https://eprints.gla.ac.uk/97823/ His notebooks are aslo in Glasgow.
