Is it capped at the top?
feels almost like earth/dirt with little pebbles in it
Where did it come from? Inside? This might be the stuff that was used to 'seal' the chimney. It's that crazy stuff with horse hair in it. Older chimneys would have been just brickwork, later would have had a layer of something to better prevent gases from exiting through the brickwork and in to the building.
edit: called pargetting, a rough coat of lime mortar

sorry, the earthy plaster is with pebbles is on a different wall - all the crap in the chimney was fine and black, not sure whether it’s capped up top or not tbh, still need to find a roofer to get up there
edit: was also thinking about getting a chimney sweep for good measure, even if we’re never going to have a proper fire or stove in there

got damp plaster from the chimney..? just add another layer on top!
hopefully opening it up and filling the two bags in the photo with the soot and earth that was in the hole will help things considerably.
in the other photo is some plaster that has blown (which we’ve then given a hand) - feels almost like earth/dirt with little pebbles in it - any idea if this stuff can go in regular skips unlike gypsum plasterboard waste?
