Paragon says sampling at Lesotho project shows high diamond grades

12 april 2012

Paragon Diamonds said further bulk sampling at its 83.7 percent owned Lemphane project, in Lesotho has showed increased grades and larger diamonds from tailings reprocessing.
Lemphane was one of five known diamond bearing kimberlite pipes within Lesotho.
It said in a statement that the sample had recovered 90.25 carats at an average diamond size of 0.38 cts/stone as well as seven diamonds ranging from 2.0-6.3 carats.
Twenty two diamonds greater than one carat in weight were also recovered, Paragon said.
Re-processing of re-crushed tailings from the first Lemphane sample also yielded a further 5.08 carats from 9 diamonds, including a single 3.85 carat stone to raise the total carats recovered to 51.87 carats and the overall grade of the sample from 1.96 cpht to 2.20 cpht.
The proportion of carats present in +2 carat stones increased from 39 percent to 43 percent.
Paragon chairman Francesco Scolaro said the results were positive and continued to confirm their initial expectations of large and high quality stones in line with other high value Lesotho kimberlites.
Meanwhile, the diamond junior said bulk sampling was also recently completed at a small satellite pipe adjacent to Lemphane, which recovered a total of 18.49 carats in 74 diamonds at 3.21 cpht and at an average stone size of 0.24 carats per stone.
Paragon said the grade at the satellite was 50 percent higher than the main pipe, but the average stone size and proportion of larger diamonds was lower.
