Yes that's the same story, also the coins will be on display at the Buxton Museum from October.
http://www.derbyshire.gov.uk/leisur.../default.aspImpossible to know the reason for why the coins were buried in the cave, but I would imagine it was either in a period of instability and someone was burying their own coins and could not retrieve them for some reason, or they were stolen from somewhere and hidden there. I do not know that area too well (being a southerner) but it seems 2000 years ago it would have been a pretty remote spot, especially a cave.
Then again who knows, could of even been some type of religious offering.
Vermontensium, the Peak District is a mountainous area in northern England, a very popular place for tourists so even more surprising that some iron age coins were just found in a cave, as I would imagine many people already would have gone through the same cave many times, perhaps not with a metal detector though, if that was how they were found.
