Highlights
Mineral study on bulk sample CF-R1-7 has identified a white/transparent dodecahedron microdiamond that is approximately 0.2mm in size.
This diamond discovery is importantly located on the opposite side of the Riachao kimberlite approximately 670m from where previous diamonds have been recovered.
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.
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.
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.
