ANNOUNCES POSITIVE BULK
SAMPLING RESULTS FROM
MARAVILHA DIAMOND PROJECT
Toronto, ON - Five Star Diamonds Limited (TSXV: STAR) (the
“Company” or “Five Star Diamonds”) is extremely pleased to
provide final results from its initial bulk sampling of the M3
Kimberlite pipe located at its 100% owned Maravilha Diamond
Project (the “Maravilha Project”) in Brazil.
Highlights
Ø A total of 658 macro and microdiamonds recovered
from first 1 tonne bulk sample.
Ø A total diamond weight achieved of 0.63 carats.
Ø Approximately 87.5% or 576 of the diamonds
recovered are transparent in nature and 92.7% or
610 diamonds are white in colour.
Ø Additional bulk sampling and drilling programmes
are currently being planned to fast track this
project and the M3 kimberlite discovery.
Ø A further six possible kimberlite targets have been
identified across the Maravilha Project.

“The Company is extremely encouraged with the positive results from the first bulk
sample program at the M3 kimberlite pipe, which exceeded our expectations,” said
Matthew Wood, President and CEO. “This is an exceptional early result and a very positive
outcome for all stakeholders.”
“Additional bulk sampling and drilling programs are being planned for the M3 kimberlite
pipe and six new potential kimberlite targets have been identified at the Maravilha
Project. We will look to fast-track work at the promising M3 kimberlite discovery,” added
Mr. Wood.
MARAVILHA DIAMOND PROJECT
Five Star Diamonds is extremely pleased to announce the final results of a bulk sampling
program to test the M3 kimberlite pipe. The M3 kimberlite pipe lies within the Sao
Francisco Craton and is hosted by Archean meta granites and meta basalts. A ground
magnetic survey indicated that the M3 kimberlite pipe has a strong magnetic response
suggesting an ovoid shape measuring approximately 130 by 65 meters with the major
axis aligned along a northeast southwest direction.
Earlier this year the Company submitted a 1.04 tonne bulk sample (CF-MAR-1) for caustic
fusion and diamond analysis at the SGS Geosol Laboratory (“SGS Geosol”), based in Belo
Horizonte, Brazil.
The dissolution by caustic fusion (NaOH) of the weathered kimberlite sample was
performed by SGS Geosol and no crushing was undertaken anywhere in the process in
order to minimise the risk of breakage of diamonds. A total of 36 pours were necessary to
dissolve the sample from its original mass of 45.81 kilograms to a final residue of 12.87
grams.
SGS Geosol monitored the quality control and assurance of the caustic fusion process by
adding a total of 20 synthetic diamonds to each fusion at the start of the dissolution
process. Ten synthetic diamonds (-250 µm to + 180 µm) and 10 synthetic diamonds (-
0.850 µm to +425 µm) were added. The average recovery was 99%.
The residues of the analyzed sample were screened in 11 screen sizes down to a bottom
cut off +75 microns (“µm”) in size and each size fraction was sorted twice, checked and
re-checked. A total of 658 macro and microdiamonds were recovered.
All macrodiamonds and each microdiamond greater than 300 µm was weighed
individually and microdiamonds below 300 µm were weighed by groups. SGS Geosol used
five decimal place electronic microbalance to weigh the stones in grams and the gram
weights were subsequently converted into carats. The total weight of all 658 diamonds
totalled 0.62944 carats and the breakdown is indicated in the table below.
All the diamonds recovered were described in terms of their physical characteristics,
including crystal shape, clarity, colour and corrosion features.
The most common crystal shapes included broken dodecahedron, broken octahedron,
broken complex crystals and other fragments. A total of 13 dodecahedron and 9
octahedron crystals were also recovered.

Approximately 87.5% or 576 of the diamonds recovered are transparent in nature while
the remainder are translucent or opaque. A further 610 diamonds or approximately
92.7% of the recovered diamonds are white in colour, with the remaining being grey,
brown and yellow. The most common corrosion features are frosted followed by trigons.
Approximately 61% of the population contain a certain degree of inclusions.

Next Steps
The Company is now planning a follow up program that will include a drilling of the M3
Kimberlite to an initial depth of approximately 200 metres. Additional and larger bulk
samples will also be taken with the aim of collecting a larger parcel of diamonds for initial
diamond valuation work.
The Company will also continue its current ground magnetic survey and auger drilling
program on the larger licence with the aim of identifying additional kimberlites in the
Maravilha kimberlite cluster for bulk sampling.
ABOUT FIVE STAR DIAMONDS
Five Star Diamonds is listed on the TSX Venture Exchange under the ticker symbol
STAR. The Company controls a dominant and highly enviable position in the Brazilian
kimberlite diamond sector owning 23 diamond projects comprising an aggregate of 49
exploration licences and applications across 130,237 hectares.
To date, the Company has conducted exploration programs on seven projects with the
Catalao, Verissimo, Riachao, Jaibaras and Maravilha Projects proven to contain diamond
bearing kimberlites.
Five Star Diamonds is focused on acquiring and developing advanced staged diamond
projects in Brazil. Since it was established, it has pursued an accelerated growth strategy
and aims to be one of the first producers of diamonds from kimberlite deposits in Brazil.
The Company is focused on the development of sustainable kimberlite pipes and is not
involved in alluvial diamond mining with its associated environmental issues. The
Company works closely with local, state and federal authorities in Brazil to foster an open,
transparent and legal diamond industry in Brazil.
This release is an update by the Company on its 100% owned Maravilha Diamond Project.
It is expected that the company will be able to provide further updates on this and its
other Projects over the coming months and we look forward to keeping shareholders
informed of our progress as we move towards building a truly unique Brazilian Diamond
Company.
