TSXV: STAR
JAIBARAS DIAMOND PROJECT
DRILLING AND BULK SAMPLING
COMPLETED
Toronto, ON - Five Star Diamonds Limited (TSXV: STAR) (the “Company”
or “Five Star Diamonds”) is very pleased to advise that it has successfully
completed its diamond drilling and bulk sampling programmes at its
100% owned Jaibaras Diamond Project (the “Jaibaras Project” or “the
Project”) in Para State, Brazil.
Highlights
Ø An initial programme totalling 1,536m of diamond
drilling for 49 holes was completed on the J1, J2 and J4
kimberlite pipes.
Ø A total of 23 mini-bulk samples will be collected from
the drilling programme that successfully intersected
kimberlite rock. These samples which will only contain
the full saprolite zones of the core will be submitted to
South Africa for caustic fusion and diamond analysis.
Ø Additional bulk sampling has also been concluded on
four kimberlite pipes, J1, J2, J3 and J4. A total of 120
tonnes of material has been processed through the
company’s jig concentrate plant at the Project.
Ø 1,110 kgs of concentrate is being transported to the
Catalao diamond recovery plant for processing across
the X-Ray flow sort.
Ø Bulk sampling results are expected over the coming
weeks.
Ø In addition 6 smaller bulk samples of approximately 1
tonne each were collected from pipes J1, J2 and J4.
These samples are currently in storage and will also be
submitted to South Africa for caustic fusion and
diamond analysis.
Ø The Company expects that the completion of the above
programme will determine an early stage approximate
value, grade and tonnage for the J1, J2 and J4 Kimberlite
pipes.

JAIBARAS DIAMOND PROJECT, PARA STATE
The Company has recently successfully completed its initial diamond drilling and bulk
sampling programmes at the Jaibaras Diamond Project.
Drilling Programme
Diamond core drilling focused on the J1, J2 and J4 kimberlite pipes. A total of 25 drill
holes were completed at the J1 kimberlite pipe, 18 drill holes completed at the J2
kimberlite pipe and six drill holes at the J4 kimberlite pipe.
Drilling at Jaibaras Diamond Project
The key objective of the drill programme was to cross cut the clay weathered zone and
penetrate approximately five metres into the fresh rock. This will now allow the
Company to delineate the lateral boundaries of each pipe and the vertical depth extent of
the clay weathered zone. It has allowed the Company to now possess the relevant
information required to conduct a tonnage estimation of the clay weathered zones.

25 vertical diamond drill holes were completed totalling 766.65 metres.
11 holes successfully intersected kimberlite at the J1 kimberlite pipe.
18 vertical diamond drill holes were completed totalling 577.30 metres.
8 holes successfully intersected kimberlite at the J2 kimberlite pipe.

Bulk Sampling Programme
A total of eight bulk samples were collected from the drilling programme. Two samples
each from J1 Kimberlite Pipe, J2 Kimberlite Pipe, J3 Kimberlite Pipe and J4 Kimberlite
Pipe were collected totalling approximately 120 tonnes.
The 0.5tph bulk sampling jig plant at Jaibaras has completed processing these eight
samples and a total of 1,110 kg of concentrate has been prepared for shipment to the
Company’s diamond recovery plant in Catalao City where it will be processed across the
X-Ray Flow Sort.

Concentrate currently under transport to the diamond recovery plant in Catalao for processing
A total of 23 mini-bulk samples will be collected from the drilling programme that
successfully intersected kimberlite rock. These samples which will only contain the full
saprolite zones of the core, ignoring the overburden at the top and the fresh rock at the
bottom will be submitted to South Africa for caustic fusion and diamond analysis. Once
collected this will assist the Company in creating a tonnage estimate on the pipes drilled.

Previous mini bulk sampling of the J1 and J2 kimberlite pipes undertaken last year
resulted in the recovery of gem quality macro diamonds from clay weathered kimberlite.
The concentrate processed from the eight samples is currently being transported to the
Company’s Diamond Recovery Plant in Catalao City for diamond recovery.
