Jaibaras Diamond Project Drilling and Bulk Sampling Completed
TORONTO, Aug.29, 2017(GLOBE NEWSWIRE) -- Five Star Diamonds Limited (TSXV:STAR) (the "Company" or "Five Star Diamonds") is very pleased to advise that it has successfully completed its diamond drilling and bulk sampling programmes at its 100% owned Jaibaras Diamond Project (the "Jaibaras Project" or "the Project") in Para State, Brazil.

Highlights
- An initial programme totalling 1,536m of diamond drilling for 49 holes was completed on the J1, J2 and J4 kimberlite pipes.
- A total of 23 mini-bulk samples will be collected from the drilling programme that successfully intersected kimberlite rock. These samples which will only contain the full saprolite zones of the core will be submitted to South Africa for caustic fusion and diamond analysis.
- Additional bulk sampling has also been concluded on four kimberlite pipes, J1, J2, J3 and J4. A total of 120 tonnes of material has been processed through the company's jig concentrate plant at the Project.
- 1,110 kgs of concentrate is being transported to the Catalao diamond recovery plant for processing across the X-Ray flow sort.
- Bulk sampling results are expected over the coming weeks.
- In addition 6 smaller bulk samples of approximately 1 tonne each were collected from pipes J1, J2 and J4.These samples are currently in storage and will also be submitted to South Africa for caustic fusion and diamond analysis.
- The Company expects that the completion of the above programme will determine an early stage approximate value, grade and tonnage for the J1, J2 and J4 Kimberlite pipes.
JAIBARAS DIAMOND PROJECT, PARA STATE
The Company has recently successfully completed its initial diamond drilling and bulk sampling programmes at the Jaibaras Diamond Project.
Drilling Programme
Diamond core drilling focused on the J1, J2 and J4 kimberlite pipes. A total of 25 drill holes were completed at the J1 kimberlite pipe, 18 drill holes completed at the J2 kimberlite pipe and six drill holes at the J4 kimberlite pipe.

Drilling at Jaibaras Diamond Project
The key objective of the drill programme was to cross cut the clay weathered zone and penetrate approximately five metres into the fresh rock.This will now allow the Company to delineate the lateral boundaries of each pipe and the vertical depth extent of the clay weathered zone.It has allowed the Company to now possess the relevant information required to conduct a tonnage estimation of the clay weathered zones.

25 vertical diamond drill holes were completed totalling 766.65 metres.
11 holes successfully intersected kimberlite at the J1 kimberlite pipe.

Bulk Sampling Programme
A total of eight bulk samples were collected from the drilling programme. Two samples each from J1 Kimberlite Pipe, J2 Kimberlite Pipe, J3 Kimberlite Pipe and J4 Kimberlite Pipe were collected totalling approximately 120 tonnes.

The 0.5tph bulk sampling jig plant at Jaibaras has completed processing these eight samples and a total of 1,110 kg of concentrate has been prepared for shipment to the Company's diamond recovery plant in Catalao City where it will be processed across the X-Ray Flow Sort.

Concentrate currently under transport to the diamond recovery plant in Catalao for processing
A total of 23 mini-bulk samples will be collected from the drilling programme that successfully intersected kimberlite rock.These samples which will only contain the full saprolite zones of the core, ignoring the overburden at the top and the fresh rock at the bottom will be submitted to South Africa for caustic fusion and diamond analysis.Once collected this will assist the Company in creating a tonnage estimate on the pipes drilled.
Previous mini bulk sampling of the J1 and J2 kimberlite pipes undertaken last year resulted in the recovery of gem quality macro diamonds from clay weathered kimberlite. The concentrate processed from the eight samples is currently being transported to the Company's Diamond Recovery Plant in Catalao City for diamond recovery.

Next Steps
The Company expects that the completion of the above programme will determine an early stage approximate value, grade and tonnage for the J1, J2 and J4 kimberlite pipes.
Unlike kimberlite discoveries in Canada, where kimberlite pipes are primarily very deep, the Company's projects in Brazil are close to surface, meaning the Company can undertake its work in a modest and quick manner.The Jaibaras Project is no different and a substantial amount of work has been completed in a very short period of time.
The Company will continue to conduct additional work on the Jaibaras Project with the following activities also underway
- Approximately 350 density measurements on 23 diamond cores.
- A petrographic study on fresh kimberlite rock intersected on J1, J2 and J4 kimberlite pipes
- On-going assessment of new licence positions at the Jaibaras Project including a focus on obtaining an Operation License and the submitting of a technical report with a view to obtaining a Trial Mining License on the Jaibaras Project.
