TSXV: STAR

FIRST DIAMONDS RECOVERED

FROM MARAVILHA KIMBERLITE

DISCOVERY

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

“Company” or “Five Star Diamonds”) is extremely pleased to provide

the following update on its 100% owned Maravilha Diamond Project

(the “Maravilha Project” or “the Project”) in Minas Gerais State, Brazil.

Highlights

Ø The Maravilha diamond discovery is a new and exciting

near surface diamond-bearing kimberlite discovery in

Brazil.

Ø Mineral study from the bulk sample CF-MAR-1 on the

M3 kimberlite pipe has identified a total of seven

diamonds during initial examination of concentrates.

Ø Three white and transparent macro -

diamonds (>0.5mm) and four microdiamonds have

been identified under microscope.

Ø Bulk sampling will continue across the M3 kimberlite

pipe with other targets identified and currently been

treated. These will be prepared for caustic fusion and

diamond analysis.

Ø A detailed ground magnetic survey has also been

completed on the recently acquired, extended portion,

of the Maravilha Project.

MARAVILHA DIAMOND PROJECT, MINAS GERAIS STATE

Five Star Diamonds Maravilha Diamond Project comprises two Exploration Licences

covering a total area of 1,114.86 hectares located in Minas Gerais State.

The Company recently reported that a detailed geology mapping and ground magnetic

survey was completed along with the commencement of initial mini-bulk sampling of the

M3 Kimberlite pipe. The M3 kimberlite lies within the Sao Francisco Craton and is hosted

by Archean meta-granites and meta-volcanic basalts. Ground magnetic survey indicated

that the M3 pipe has a strong magnetic response suggesting an ovoid shape measuring

130 by 65 meters with the major axis aligned along a northeast-southwest direction.

During a recent in-house microscope study of the heavy minerals from this initial mini-

bulk sample CF-MAR-1 a total of 7 (seven) diamonds were identified. Three of the

diamonds recovered are described as white and transparent macrodiamonds [>0.5 mm

in size] with the remaining four diamonds classed as microdiamonds. One of the

microdiamonds is a perfect white and transparent octahedron crystal.

These stones have been returned to the concentrate for future treatment and recovery by

caustic fusion and microdiamond analysis.

Mini-bulk sampling will continue across the M3 kimberlite pipe and other targets from

the geology and magnetic survey identified.

All samples will be individually pre-treated (washing, sieving and drying) to generate

concentrates for diamond analysis (caustic fusion/MiDA) with results expected early in

2018.

The Company also recently acquired an adjacent property immediately east of Maravilha

with the Company reporting that the property contains Kimberlite Indicator Minerals

(KIM’s) similar to the diamond-bearing M3 pipe but has never been tested for diamonds.

Next Steps

These are exceptional early results at the Maravilha Diamond Project and additional

assessment will be undertaken, including trenching and drilling to delineate the M3 pipe.

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 23 diamond kimberlite projects comprising

an aggregate of 67 exploration licences and applications across 165,019 hectares.

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.

It is expected that the company will be able to provide further updates on this and its
