commercialization project.

 The oxide commercial plant is largely now on site and

in the final design and pre construction phase.

Approximately 80% of capital expenditure has been

completed.

 The oxide commercial plant will utilize a Dense Media

Separator (DMS) to recover concentrates which will

then be processed at the c ompany’s existing diamond

recovery plant in Catalao City.

anticipation of the commencement of construction and

an expanded mining operation.

 The Company expects to be able to provide further

Five Star Diamond’s Project Locations

Five Star Diamond’s business is diamond development. It 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.

The flagship project of Five Star Diamonds is the 100% owned advanced stage Catal ao

diamond project located in the famous Coromandel diamond district of Brazil . The Project

comprises one exploration licence covering 1,999.42 hectares. In addition, the Company has

submitted applications for three exploration licences over proximate areas covering a total

of 5,998.37 hectares.

In 1853, a diamond discovered in Coromandel became the first large Brazilian diamond

whose history is fully authenticated. It was named “Estrela do Sul” (Star of the South) and

weighed 261.9 carats. Additional notable stones discovered in the same area include one

weighing 122.5 carats (found four years later, in 1857). Other notable stones authenticated

are 118 carats (1929), 108 carats (1940), and 174.5 carats (1954).

A pilot plant was constructed by the Company in Catal ao and commissioned, and an initial

mining and pilot processing program was completed on the oxide zones at three diamond

bearing kimberlite pipes. A feasibility study is currently underway to evaluate the fresh rock

zone.

Cautionary Note Regarding Catalao Production Decision

The decision to commence production at the Catalao Diamond Project and the Company's

plans for a mining operation as disclosed herein (the "Production Decision ") were based on

economic models prepared by the Company in conjunc tion with management's knowledge

of the property and the existing indicated and inferred mineral resources on the property.

The Production Decision was not based on a preliminary economic assessment, a pre -

feasibility study or a feasibility study of mine ral reserves demonstrating economic and

technical viability. Accordingly, there is increased uncertainty and economic and technical

risks of failure associated with the Production Decision, in particular the risk that mineral

grades will be lower than expected, the risk that construction or ongoing mining operations

are more difficult or more expensive than expected, the risk that the Company will not be

able to transport or sell the mineralized rock it produces on the terms it expects, or at all;

production and economic variables may vary considerably, due to the absence of a detailed

economic and technical analysis normally contained in a feasibility study.

The Company wholly owns four diamond process plants in Brazil

 0.5tph mobile wash and jig concentrate bulk sampling plant.

 5tph wash and rotary pan concentrate plant. Recently completed the pilot programme

at Catalao and is now planning to mobilise to the Jaibaras Diamond Project.

 100tph wash and 30tph DMS concentrate plant. This is currently in final design and

pre-construction at Catal ao. The world renowned diamond processing group, ADP

Group have been appointed to complete the design work. ADP will also construct and

commission this plant . Approximately 80% of capital expenditure has been

completed. Key site appointments are now being made in anticipation of the

commencement of construction and an expanded mining operation on site . The

Company expects to be able to provide further updates in the coming months

including an estimation for the commencement and potential sale of its first

commercial diamond production.

 High security diamond recovery and sorting plant located nearby in Catalao City.

Selection of run of mine diamonds from the successful Catalao Diamond Project pilot operation

The Company recently transported a small parcel of diamonds to Antwerp , Belgium for

cleaning and assessment. This parcel of diamonds, mined in the pilot programme at Catalao,

have been classed as uniquely pure quality with pure to VS in almost 85% of the diamonds

viewed. In addition, fluorescence was 99% absent. These are unique and highly desirable

characteristics in diamonds and very few known mining concessions are able to produce such

top end colors almost entirely.

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

kimberlite diamond sector. Along with the Catalao Project, the Company owns 22 other

diamond kimberlite projects comprising an aggregate of 72 expl oration licences and

applications covering a total area of 123,667 hectares.

All of the Company’s projects are 100% owned and have been previously explored by either

Rio Tinto or De Beers. A total of 15 diamond bearing kimberlite pipes have already been

sampled by Five Star Diamonds and a further 87 kimberlite pipes are to be tested across the

Company’s projects.

Catalao Project run of mine diamonds in Antwerp after cleaning

The Company has now successfully listed on the TSX -V, under the ticker symbol STAR, and

looks forward to an aggressive work programme at its diamond projects across Brazil. This

will be the first of many announcements over the coming months and we look forward to

keeping shareholders updated on our progress as we move towards building a truly unique

Brazilian Diamond Company.
