[QUOTE="mbasko, post: 609168, member: 4485"] Possibly around 22 grams? That's using an SG of 2.5 for the host rock (common rock types SG between ~2.5 - 3.5). Iron ores like hematite & magnetite SG at 4.9 to 5.2. If you use that SG you get a negative result i.e. -81 grams. Rock speccis or material made up of various minerals can be hard to work out accurately. Best way to know accurately for us mug punters is to crush it like Kingswood did. [/QUOTE]
