Color diamonds are more valuable and desirable and a better investment

In 1993, Eyal Cohen started his career as a diamond cutter, sitting by his father’s side as an apprentice. 4 years later, he was recruited by a jewelry firm, where he learned to appreciate natural colored diamonds. In 2003, Eyal opened his own company...

Lucapa says Lulo partners to conduct further work on L14 kimberlite pipe

14 november 2017
Lucapa Diamond and its partners, Endiama and Rosas & Petalas said mineral chemistry results from initial seven Lulo kimberlites provide support for further work only at the L14 kimberlite pipe upstream of Mining Block 8 at the Lulo diamond project in Angola.
The seven Lulo kimberlites were L13, L14, L15, L18, L171, L242 and L252.
Lucapa said whilst the mineral chemistry results from the initial seven kimberlites suggested derivation of the indicator minerals from the upper mantle, they were largely from shallow depths and high temperatures believed to be from outside the diamond stability field.
It said the partners were planning to do follow-up testing of L14 kimberlite and would incorporate this into the current kimberlite exploration programme.
A G4D garnet was recovered from the core of kimberlite L14, last May from the time domain electromagnetic survey flown over the Cacuilo River valley area at Lulo.
G4D garnets were associated with eclogitic/websteritic material from within the diamond stability field.
The partners had been conducting a systematic drilling programme, utilising up to three rigs, to drill kimberlite targets identified near the Lulo alluvial diamond mining operations, where significant quantities of large diamonds had been recovered.
This, said Lucapa, builds on earlier exploration and bulk sampling work at Lulo in which five kimberlites were confirmed as diamondiferous pipes.
It also said that consultants were currently on site at Lulo selecting the next batch of kimberlite core samples for dispatch to Cape Town for mineral chemistry analysis.
“These laboratory results will in turn be used to prioritise a much reduced number of likely diamondiferous kimberlites for follow-up test work, including further drilling and bulk sampling to assess diamond content,” it said.
