[QUOTE="mbasko, post: 443333, member: 4485"] I think you'd be wasting your time looking for the black rocks. The coating is more likely to be an oxide crust from surrounding rocks (probably the basalt - iron rich) which would again likely be a type of an iron oxide depending on area. Possibly hematite, magnetite or even include an oxide of manganese ores? Have seen nuggets like this before from Tambaroora NSW. Edit: p.s. post a pic of them here [url]https://www.prospectingaustralia.com/forum/viewtopic.php?pid=443309#p443309[/url] goldierocks could probably give you a more accurate answer based on your general location?
