[{"type":"text","content":"TORONTO, ONTARIO--(Marketwired - May 30, 2017) - Five Star Diamonds Limited (TSX VENTURE: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 The Company has discovered a large kimberlite pipe at the Riachao Diamond Project. The kimberlite pipe at Riachao is interpreted to be approximately 24 Ha in size, which is large on a global scale, and the largest kimberlite pipe the Company has identified to date amongst its 23 diamond projects in Brazil. Significant historical alluvial diamond production in the region surrounding the kimberlite discovery at Riachao. A detailed ground magnetic survey and surface reconnaissance mapping have recently been completed by the Company. Initial Kimberlite Indicator Minerals (\"KIM\") studies conducted by the company have been highly encouraging. This work continues. The weathered kimberlite outcrops at surface and two 100kg mini-bulk samples are now being collected and prepared for caustic fusion and micro diamond analysis. Five Star Diamonds Riachao Diamond Project comprises 1 Exploration Licence covering a total area of 1,278,13 hectares. Figure 1 The Company recently completed a programme of detailed ground magnetics and reconnaissance geological mapping across the Riachao Diamond Project. This initial work programme has been successful in identifying a kimberlite pipe of approximately 24 Ha in size, which is large on a global scale, and the largest kimberlite pipe the Company has identified to date amongst its 23 diamond projects in Brazil. The pipe is peripheral to significant historical alluvial diamond production and the Company is now working towards determining if the pipe is diamond bearing or not. The ground magnetic programme was composed of 44.1 linear kilometres of surveyed lines with 10m spacing between each line and constant readings along lines. A total area of 42.81Ha was covered by the survey. As part of the ground magnetic programme a programme of initial reconnaissance geological mapping was also completed. This highlighted abundant outcrops of clay weathered kimberlite within the survey area. A 40kg mini-bulk sample was collected from surface outcrops on kimberlite. This was disaggregated and washed to produce ...
