NEW DISCOVERY ESTABLISHES

DIAMONDS ACROSS A WIDE AREA

AT RIACHAO PROJECT

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 Riachao Diamond Project (the

“Riachao Project” or “the Project”) in Piaui State, Brazil.

Highlights

Ø Mineral study on bulk sample CF-R1-7 has identified a

white/transparent dodecahedron microdiamond that

is approximately 0.2mm in size.

Ø This diamond discovery is importantly located on the

opposite side of the Riachao kimberlite approximately

670m from where previous diamonds have been

recovered.

Ø Recently completed auger drilling, mapping and

detailed ground magnetics completed at the Riachao

Project has confirmed the presence of a 25ha

kimberlite pipe at surface . This is the largest

kimberlite pipe the Company has identified to date

amongst its 23 diamond projects in Brazil.

Ø Stage-2 sampling at the Riachao Project has been

completed with seven 1t samples collected for caustic

fusion and diamond analysis. Results are expected

early in 2018.

RIACHAO DIAMOND PROJECT, PIAUI STATE

The Riachao Diamond Project is located in Piaui State and comprises one exploration

licence covering a total area of 1,278.13 hectares. It is located within a geological

province known as the “Gilbues Diamondiferous Province”.

Additional Caustic Fusion and Diamond Analysis

The Company recently reported the completion of a second and more extensive caustic

fusion and diamond analysis programme. The total programme comprised seven

samples which combined have an original total wet weight of 7,117 kgs. These samples

were individually pre-treated (washing, sieving and drying) to generate concentrates for

diamond analysis (caustic fusion/MiDA). A total of 308.38 dry kilograms of concentrates

were produced it total.

The first four samples labelled CF-R1-3, CF-R1-4, CF-R1-5 and CF-R1-6 have arrived in

South Africa for caustic fusion and diamond analysis at The MSA Group.

The remaining three samples labelled CF-R1-7, CF-R1-8 and CF-R1-9 have been prepared

and are ready for delivery to South Africa.

During a brief mineral examination of concentrates a diamond was identified in sample

CF-R1-7. The diamond is a white/transparent, dodecahedron microdiamond and has a

size of approximately 0.2mm. This stone has been returned to the concentrate for

treatment and recovery by caustic fusion and microdiamond analysis.

This is further verification that the Riachao kimberlite is diamond bearing across large

areas with white transparent diamonds now recovered at both extremes of the kimberlite

(670 metres apart). Further work at Riachao will be a focus for the Company over the

coming months as it advances a sampling program of the 25ha kimberlite pipe that is out

cropping at surface.

Location of mini-bulk samples recently collected (CF-R1-3 to CF-R1-9).

In May 2017, the Company 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

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

series of weathered kimberlite outcrops. Two outcrops (28 metres apart) were selected

on the eastern side of the target and one mini-bulk sample was collected on each of these

two sites. The surficial exposure of the selected outcrops was 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. In total, the two mini-bulk samples

yielded 13 natural microdiamonds, from an original weight of 195.25 kilograms.

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.

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.

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.
