RIACHAO DIAMOND PROJECT, PIAUI STATE

Stage Two Programme

New work programmes have now commenced at the Riachao Project which include auger

drilling, bulk sampling, detailed geological mapping and additional ground magnetics.

Auger Drilling Planned at Riachao Diamond Project

The auger drilling programme was designed using a grid of 100x100 metres. The design

includes drilling 26 holes to cover the entire kimberlite area. It is anticipated that certain

zones will be infilled to 50x50 meters. The Company will collect all material from each

hole for composition into bulk samples for caustic fusion and diamond analysis. Detailed

mapping across the Riachao kimberlite has also commenced. Additional bulk sample

locations will be selected from this mapping and auger drilling programme.

The company is nearing completion of a detailed remote sensing analysis over the entire

mineral property. Two circular to sub-circular features have already been selected and

ground magnetic testing and mapping has already commenced testing for the presence

of kimberlite.

Five Star Diamonds Riachao Diamond Project comprises one Exploration Licence

covering a total area of 1,278.13 hectares located on the southern portion of Piaui State,

within a geological province known as the “Gilbues Diamondiferous Province”.

The Company had previously completed a detailed ground magnetic survey over a small

pre-selected target area inside the Riachao mineral property and, as a result of this

survey, a potential kimberlite target was delineated with an interpreted size of

3 | Page

approximately 25 hectares. A preliminary surface inspection revealed the presence of a

series of weathered kimberlite outcrops. This has since been confirmed as the largest

kimberlite pipe the Company has identified to date amongst its 24 diamond projects in

Brazil.

Two outcrops (28 metres apart) were selected on the eastern side of the target and one

100kg sample was collected on each of these two sites. The surficial exposure of the

selected outcrops were cleaned and volumetric samples of clay weathered kimberlitic

rocks were manually collected with the help of a hoe and a hammer, roughly on sub-

vertical channels.

As previously reported a recently completed caustic fusion and microdiamond analysis

from two 100kg samples yielded a total of 13 natural diamonds. The 13 natural diamonds

are transparent, with 10 of the stones being white/colourless. This is an exceptional early

result and has encouraged the Company to immediately commence additional

programmes on the project. The Riachao kimberlite pipe occurs on or very close to

surface and the Company will be able to undertake its initial follow up programmes at a

modest cost and quick manner.

ABOUT FIVE STAR DIAMONDS

Five Star Diamonds is listed on the TSX Venture Exchange under the ticker symbol STAR

and has recently signed a cooperation agreement with leading global diamond house

Hennig Limited.

The Company controls a dominant and highly enviable position in the Brazilian

kimberlite diamond sector owning 24 diamond kimberlite projects comprising an

aggregate of 80 exploration licences and applications across 185,980 hectares.

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 Riachao Diamond Project.

The Company is also running active programmes across its 100% owned Jaibaras,

Catalao, Verissimo and Caiapo Diamond Projects. It is expected that the company will be

able to provide further updates 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.
