Lumbridge swamp mine
There's Lumbridge Swamp mine, which has tin and copper rocks only, and there's South-west Lumbridge swamp mining site, which is more advanced with coal, mithril, and adamantite rocks. You appear to have got them mixed up, and vandalised the page for the latter in your confusion. 07:03, August 4, 2018 (UTC)
