following update on its 100% owned Jaibaras Diamond Project (the

“Jaibaras Project” or “the Project”) in Para State, Brazil.

Highlights

Ø Construction of the 0.5tph bulk sampling plant at

Jaibaras is completed.

Ø A 20t bulk sampling has commenced on the J3

kimberlite target.

Ø On completion of bulk sampling at J3 kimberlite, the

Company will process similar sized samples from J1,

J2 and J4 kimberlite pipes. J5-J8 kimberlite pipes

remain under assessment.

Ø The Company has two diamond core drilling rigs

operating on the Jaibaras Diamond Project. Initial

drilling results from the J1 and J2 kimberlite pipes

are meeting the Company’s expectations.

Ø A total of 34 diamond core drill holes have now been

successfully completed on the J1 and J2 kimberlite

pipe.

Ø Both drilling rigs are currently operating on the J2

kimberlite pipe and 14 holes have been completed.

JAIBARAS DIAMOND PROJECT, PARA STATE

The Company has commenced its bulk sampling and continues its drilling programme at

the Jaibaras Diamond Project. The Company maintains two drilling rigs on site and has

commenced a 20t bulk sampling on the J3 kimberlite target. Similar samples will be

processed from the J1, J2 and J4 kimberlite pipes. A total of eight kimberlite pipes (J1-J8)

have been identified and continue to remain under assessment and evaluation at Jaibaras.

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.

Construction of the 0.5tph bulk sampling plant is now completed and will commence

processing a 20t sample from the J3 kimberlite pipe. The bulk sampling plant is a 0.5tph

mobile wash and jig concentrate sampling plant which recovers diamonds above 1.5 mm

in size. As observed from recently completed programmes the kimberlite pipes at

Jaibaras occur on or very close to surface which allows the Company to quickly test the

diamondiferous quality of the pipes. Initial results from the bulk sampling programme

should be available in the coming month.

Diamond core drilling focusing on the J1 and J2 kimberlite pipes is well underway with

20 drill holes completed at the J1 kimberlite pipe and 14 drill holes completed at the J2

kimberlite pipe. Initial results are meeting the Company’s expectations with a total of

1,064 meters completed to date.

The key objective of the drill programme is to cross cut the clay weathered zone and

penetrate approximately five metres into the fresh rock. 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.

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.
