Australian explorer Burey Gold reports gold recoveries of 91 % for an oxide sam- ple and 90 % recovery for two sulphide samples from the Kebigada Shear Zone on its Giro gold project in the north-east of the DRC using simple CIL methodology. The oxide and two sulphide reverse circulation (RC) bulk samples were sent to SGS Mineral Services laboratory in Johannesburg, South Africa, for a gold deportment study. Commenting on the results, Chairman Burey “delighted”by recoveries from Giro samples Klaus Eckhof stated: “We are delighted by the relatively simple metallurgy at Kebigada. We also anticipate that addi- tional metallurgical studies planned on drill core will further improve recovery processes. “The Kebigada Shear Zone continues to tick all the right boxes as we gather addi- tional information on the mineralisation of the area. We now eagerly await addi- tional drilling results at Kebigada as we build towards our initial inferred resource

estimate. In addition to resource drilling at Kebigada, which is ongoing, drilling at Douze Match continues, with further results expected in the coming weeks.” The Giro gold project comprises two exploitation permits covering a surface area of 610 km² and lies within the Kilo- Moto Belt, a significant but under-explored greenstone belt which hosts Randgold Resources’ 17-million ounce Kibali group of deposits. The Kibali mine produced over 600 000 ounces in 2016. 

Diamcor updates on its Krone-Endora at Venetia project Diamcor Mining Inc, listed on the TSX-V, has provide an update on the acquisition of operational equipment associated with the closing of the over-subscribed C$5,8 million private placement previously announced on August 31, 2016. as 60 % (prior to its transport to the main treatment plant) through removal of fine materials under 1,0 mm in size.

550 000 tons of large material previously stockpiled will also be processed over the coming quarters. As part of the expansions/upgrades underway, Diamcor elected to also expand and further automate the final recovery facilities. Four additional X-ray diamond recovery units are being supplied by Flow Electronics (Pty) Ltd, with three units being earmarked for use on small and mid-size fractions of material, with the fourth being allocated to the dedicated large diamond recovery circuit being installed. In conjunction with the delivery of the modules housing these additional X-ray recovery units, other modules aimed at upgrading, automating, and expanding the sorting facilities at the project will also be installed. The company expects items associated with the dedicated large dia- mond recovery circuit to be completed shortly, with other associated items on- track for completion prior to the end of the current quarter. 

Recent efforts in developing this facil- ity largely focused on the processing of material in the +1,0 mm to -15,0 mm size fractions, with material in the +15,0 mm to -45,0 mm size fractions being stockpiled pending the final decisions on a dedicated large material crushing circuit. The installation of the finalised crushing circuit at the project is aimed at enhanc- ing processing/recoveries by liberating any diamonds held in the larger calcre- tised material previously stockpiled, while providing the potential to recover large diamonds above 15,0 mm in a dedicated large diamond recovery circuit being installed at the project’s main treatment plant. Upon completion, all material up to 45,0 mm will be processed concur- rently moving forward, and approximately

The acquisition of additional operating equipment at the company’s Krone-Endora at Venetia project in South Africa’s Limpopo Province is aimed at supporting increased processing volumes, incorporating the pro- cessing of large material up to 45,0 mm, establishing a dedicated large diamond recovery circuit, and increasing the capac- ity of the project’s final diamond recovery facilities. The project’s in-field dry-screening plant is an important element in the project’s success and has been extensively tested, refined, and developed to achieve the company’s target of reducing the mate- rial recovered from the quarry by as much
