JAIBARAS DIAMOND PROJECT

UPDATE

Toronto, ON - Five Star Diamonds Limited (TSXV: STAR) (the “Company”

or “Five Star Diamonds”) is very pleased to provide the 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 nearing completion.

Ø Bulk sampling and processing of material from the J4

kimberlite pipe is planned to commence prior to the

end of July. An initial sample of 20t is to be sampled

from the clay weathered kimberlite at J4.

Ø On completion of bulk sampling at J4, the Company will

process similar sized samples from the J1 and J2

kimberlite pipes. J3 & 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 20 diamond core drill holes have now been

successfully completed on the J1 kimberlite pipe.

Ø Both drilling rigs are currently operating on the J2

kimberlite pipe and two holes have been completed.

JAIBARAS DIAMOND PROJECT, PARA STATE

The Company is conducting an active bulk sampling and drilling programme at the

Jaibaras Diamond Project. At this stage, the Company has two drilling rigs on site and is

completing construction of the bulk sampling plant. A total of eight kimberlite pipes (J1-

J8) have been identified and are 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 nearing completion and will

commence processing a 20t sample from the J4 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.

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.

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

20 drill holes now completed at the J1 kimberlite pipe and two drill holes completed at

the J2 kimberlite pipe. Initial results are meeting the Company’s expectations with a total

of 720 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. A

small drilling programme will also be conducted on the J4 kimberlite in conjunction with

the bulk sampling programme.

Auger drilling Programmes have now been completed on targets J3 to J6.
