A breakthrough Ground Penetrating Radar (GPR) survey at the Blina diamond project indicates as yet untested alluvial trap sites with the potential to host high grade or bonanza grade diamond deposits within the ancient gravels. Numerous high quality targets have been generated. This latest GPR technology uses state of the art modern electronics to deliver a fast and inexpensive method to generate both bedrock and gravel diamond trap site targets.
Some of this recent GPR data correlates closely to historic pitting and exploration data observations of the prospective bedrock-cover contact, which indicates the modern GPR is calibrated and operating correctly, Sections A to E are examples.
The 100% owned POZ Minerals Blina diamond project in the West Kimberley region of WA covers a 40 km long diamond bearing palaeo-channel named Terrace 5. The channel drains the central section of the previously mined Ellendale diamond field which is renowned as a globally significant source of rare fancy yellow diamonds. The POZ Terrace 5 ground has previously produced significant quantities of diamonds, including fancy yellows.
The company’s GPR survey has generated numerous targets including the Channel 1 Target which is over 3,000 m long and from 100 to 200 m wide, modelled target gravels lie under only 3 to 5 m of cover. It is a diamondiferous channel with previous sampled grades up to 6.03 ct/100 t. The target requires systematic bulk sampling which has not occurred to date.
The Pothole target is over 800 m long and from 50 to 170 m wide. Modelled target gravels lie under only only 3 to 5 m of cover. This target could be an ancient waterfall, pothole or scour and represents a large and highly prospective alluvial trap site.
There are numerous additional targets which can be modelled from the GPR data and which will continue be identified leading up to the bulk sampling/trial mining program.
Blina Project Mining licenses M04/466 and M04/467 were recently granted and an historic Mining Agreement has been secured with the Bunuba Dawangarri Aboriginal Corp who represent the Traditional Owners for this area.
Permitting is underway to commence bulk sampling and trial mining operations in 2018.
