Five Star Diamonds Limited (STAR) providing an update on its 100% owned Jaibaras Diamond Project   in Para State, Brazil, said that it has completed the construction of the 0.5tph bulk sampling plant and commenced a 20 t bulk sampling programme on the J3 kimberlite target.

“On completion of bulk sampling at J3 kimberlite, the Company will process similar sized samples from J1, J2 and J4 kimberlite pipes,” the Company announced. “J5-J8 kimberlite pipes remain under assessment.”

Further, the Company added that initial drilling results from the J1 and J2 kimberlite pipes are meeting   its expectations.

“A total of 34 diamond core drill holes have now been successfully completed on the J1 and J2 kimberlite pipe,” Five Start Diamonds reported.

Presently the Company has two   drilling rigs and both are currently operating on the J2 kimberlite pipe, where the drilling of 14 holes have been completed.

“A total of eight kimberlite pipes (J1-J8) have been identified and continue to remain under assessment and evaluation at Jaibaras,” the Company said. “Previous mini bulk sampling of the J1 and J2 kimberlite pipes has already resulted in the recovery of gem quality macro diamonds from clay weathered kimberlite.”

The Company said that as the kimberlite pipes at Jaibaras occur on or very close to surface   it is able to quickly test the diamondiferous quality of the pipes. Initial results from the bulk sampling programme should be available in the coming month.

“The key objective of the drill programme is to cross cut the clay weathered zone and penetrate approximately five metres into the fresh rock,” Five Star Diamonds revealed. “This has been successful to date and will allow the Company to delineate the lateral boundaries of the pipe and the vertical depth extent of the clay weathered zone. Once completed this will then provide the necessary data to conduct a tonnage estimation of the J1 & J2 clay weathered zones.”

Meanwhile, the Company reported that the 5tph Pilot Plant wash and rotary pan concentrate plant, used to complete the pilot programme at the Company's Catalao Diamond project, has been dismantled and is awaiting granting of the trial mining licence prior to mobilisation to the Jaibaras Project.
