We believe that South Africa is a prime exploration destination. We have had 52 exploration applications outstanding for a long time and now we’ve had 16 of those 52 licences granted and we are working hard to get the others approved. One of the strengths that we’ve got is that we have a database with fairly reliable information from about the mid-1950s onwards. Using that database we then apply the latest thinking and the latest technology. So a lot of our focus is around Kimberley where we used to mine.
While out on North Arrow Minerals' Mel diamond property on Nunavut's remote Melville Peninsula, prospectors made a welcome discovery: a 62 kilogram surface sample of diamond bearing kimberlite. The sample returned 23 micro-diamonds. This prompted North Arrow to significantly increase the size of its 100% owned Mel Diamond Project from 7,500 ha to 56,075 ha. Claim staking was initiated as a result of North Arrow’s September 2017 discovery of a new diamond bearing kimberlite field at Mel, located within 20 km of tide water on the Melville Peninsula, Nunavut.
A global miner hoping to revive the Kimberley diamond industry has made a significant discovery, only 50km east of the old Ellendale mine that once produced half the world's rare fancy yellow diamonds, writes ABC Australia. Only a few weeks after Lucapa Diamond Company began drilling for lamproite on its Brooking project, it has uncovered 119 diamonds, including seven macro diamonds. The diamonds were recovered from an 86.8kg core sample in a 7.5cm drill hole at Little Spring Creek in the West Kimberley.
The Finnish Mining Authority has granted Irish diamond exploration company, Karelian Diamond Resources, an Exploration Claim in the Kaavi region of Finland. The four-year Claim, which is close to Karelian's Lahtojoki mining concession, covers an area of 28.84 Hectares surrounding the location where kimberlite boulders in till have been discovered. The finding of kimberlite is significant as these igneous rocks can sometimes contain diamonds. An exploration permit provides the holder with an exclusive right to apply for a mining permit.
Canadian miner Stornoway Diamond Co. has announced its exploration plans for the upcoming year. "With the successful construction and ramp-up of the Renard Diamond Project completed", they write, "the board of directors of Stornoway has approved a program of both brownfield and grassroots exploration aimed at both new discoveries, and the development of the existing resource upside potential at Renard.
Peregrine Diamonds reports that its 2017 resource expansion drill program has confirmed the high-grade CH-6 kimberlite extends from surface to 540 metres below surface (mbs). This represents an additional 280 metres below the 260-metre depth of the current CH-6 Inferred Resource announced on April 7, 2017. The CH-6 kimberlite remains open below 540 mbs, the current limit of drilling. Tom Peregoodoff, Peregrine’s President and CEO, said: “The results confirm that the high-grade CH-6 kimberlite extends well below the current resource base of 260 metres.
"ALROSA will play its role in diamond mining in Zimbabwe", said Zimbabwe's ambassador to the Russian Federation, Mike Nicholas Sango, to TASS news agency.
