This from Peter Bullock's post #5604.... "What has been reported is a 1 km long dike with a width averaging 2.47 m and a reported depth of 500 meters. These dimensions are subject to change with further analysis and it could get bigger or smaller. With the resource open in 3 directions at the current time we know which way this is likely to go. But we don't have to go there right now so lets do the math on what we have reported to date. 1000 m x 500 m x 2.47 m = 1.237 million m3 of kimberlite. At a tonnage ratio of 2.7 tonnes/m3 that equals 3.33 million tonnes of the green stuff. Now for the tricky part....grade. The dike has yielded an average of 3.69 carats/tonne on very small quantities to date. Bulk samples will affect this # but we know that dikes have fairly consistent grades so, what the heck, lets use this and do the math and see what we get. 3.33 mil tonnes X 3.69 carats/tonne = 12 million carats." I guess George J. that Peter in this post should have used 2.47 m. thick and 500m wide...I think that is what thru me... anyway thanks again for answering my question....is Rex mining in South Africa a fissure system or a dyke system and what is the difference between the two? Thanks..G.G.
