Lucapa Diamond has completed a preliminary exploration program on its project "Zone F" (Area F) field Orapa (Orapa) in Botswana, which included ground magnetic, electromagnetic and gravimetric studies, along with electromagnetic sensing and geochemical analysis of soil.
The program, as noted in the company, has successfully helped define the gravimetric and magnetic properties AN01 site, which will be a priority for the next phase of drilling.
"It's - well-defined magnetic anomaly measuring approximately 350m to 150m, is the priority objective for drilling within the Orapa diamond deposits", - said in a statement, distributed on Monday.
"While we are engaged in checking the results of studies used to determine the AN01, simulation spent two known kimberlites F Zone" field Orapa indicates that BK14 plot is the usual kimberlite pipe without undiscovered before branching, whereas BK38 is narrow Dyke "- continue in Lucapa.
The company also announced that this year's" Zone F "in Orapa will begin drilling program in addition, drilling will begin on the main project Lulo (Lulo) company Lucapa Angola..

Of Debswana, a joint venture between De Beers and the Botswana government, reported that the Letlhakane mine (Letlhakane) close to exhaustion of stocks of the breed.
The mine, located 50 km from the Orapa mine (Orapa), 547,447 carats were produced in 2014.
Chief Engineer Fluor South Africa Verner Kryugel (Werner Krugel) said at the Diamond Conference in Gaborone, Botswana, the company is working on a project of processing tailings at Letlhakane, thanks to which, as expected, the life cycle of the mine will be increased for 24 years.
Enterprise project for processing tailings at Letlhakane was launched in October 2011 and was aimed at studying the possibility to extend the mine life cycle due to the processing of existing stockpiles of diamondiferous rocks.
As expected, the project will process 3.6 million tonnes of ore mined and 800,000 carats of diamonds annually.
According to recent media reports, the ore reserves will be processed after completion of conventional mining operations. Producing plants could be closed in 2017.
Letlhakane mine, which was first discovered in the process of sampling and evaluating Orapa project, was the second of Debswana mine after the start of its development in 1975.
