Following on the their report of September 8, 2015 that confirmed kimberlite PK150 as significantly diamond-bearing, North Arrow today release a statement reading, "the 2015 exploration program at the Pikoo Diamond Project is now complete and new microdiamond results for the PK314 and PK311 kimberlites have increased the total number of diamondiferous kimberlites at Pikoo to four." Ken Armstrong, President and CEO of North Arrow
Zimbabwe's deputy minister of mines and mining developments, Fred Moyo, said his country has more than 100 kimberlite pipes which it needs foreign partners to help develop. He was speaking at an annual two-day mining and infrastructure indaba (an African term meaning important conference) in the capital, Harare. Foreign investors have shown little interest in investing in Zimbabwe due to the country's political situation. In addition, they have reportedly been further deterred by the government's unilateral move to merge all the firms mining in the Marange area.
Alrosa partner Botswana Diamonds' latest drilling update in the Orapa region of Botswana was met with disappointment by the market after initial field analysis suggested this rock was ultramafic rock older than the kimberlites found in the Orapa area. Two holes of the three-hole drilling programme intersected an anomaly discovered by Alrosa but they did not find what they were anticipating. There were, however, significant Kimberlite Indicator Minerals (KIMs) in its core, and these have been taken back to Russia for full analysis and identification.

Level Diamonds of Antwerp has announced a joint venture with Minico (DRC) for reopening and exploiting their mine in Western Kasai. The mine has reopened for production after almost a decade of standing idle. Following a year and a half of investments and reorganisation (administrative, operational) and a new management team, the mine is back to production. Having vast reserves in the hundreds of thousands of carats, the joint venture plans for the mine to deliver 7,000-10,000ct p/m within 6 to 12 months.
The operations of De Beers Consolidated Mines (DBCM) will dwindle further with the proposed sale of Kimberley Mines, but Philip Barton, the company’s CEO, believes that DBCM has some surprises in store for its followers. "We are actively exploring in South Africa. We really believe there are a few more diamond mines left in the country that will fit into the criteria of De Beers and Anglo American," he says. De Beers has explored SA for decades, but modern geological data collection started being stored since the late 1950s. De Beers has an enormous data base from these records.

About 35 million years ago an asteroid about 5 to 8 kilometers in diameter, travelling at a speed of about 15 to 20 kilometers per second slammed into the area that is now known as the Tamyr Peninsula of northern Siberia, Russia. Geology.com takes an in-depth look at news stories claiming the Popigai Crater is a major diamond deposit containing trillions of carats of gemstone-quality diamonds kept secret by Russia.
Kimberlites are being discovered in rapid succession at the Pikoo diamond field in central eastern Saskatchewan, and work is well underway to turn it into Canada's 'next big' play. North Arrow Minerals found three new kimberlites in March, basically doubling the size of the body and picking up indicators the body is open to the east. But you don’t get a ‘diamond region’ going without others jumping in, and in Strike Diamonds, Pikoo moved from a one company play to several. Adding to the growing din around the area, none of these companies were there first.
Only 3 months after recovering a 76.07ct diamond from Yubileynaya kimberlite pipe, Alrosa has recovered a 78ct diamond from the Mir pipe. They estimate that the stone may be valued at more than $600,000 if auctioned.
Kennady Diamonds reports its spring drill program at Faraday 1 and 2 has successfully delineated two new pipe-like kimberlites at Kennady North. Based on these results Kennady has increased its tonnage target for the Kelvin – Faraday kimberlite corridor, which they now estimate has the potential to host between 12 million and 15 million tonnes.
A team of specialists from four Australian universities say they found the exact source of a diamond-bearing rock for the first time. According to Phys.org, the rocks, known as orangeites formed from lava produced by massive volcanic eruption tens of millions of years ago, are already commonly found in South Africa. However, the new study now reveals that they may be present in much higher abundance worldwide, including in Australia.
A geologist has discovered a thorny, palmlike plant in Liberia that seems to grow only on top of kimberlite pipes—columns of volcanic rock hundreds of meters across that extend deep into Earth, and could be simple, powerful way of finding diamond-rich deposits. Miners have long known that particular plants can signal ore-bearing rocks, but the new plant, identified as Pandanus candelabrum, is the first indicator species for diamond-bearing kimberlite, says Stephen Haggerty, a researcher at Florida International University in Miami and the chief exploration officer of Youssef Diamon
Anant Singh Yadav is perhaps the only farmer in Bundelkhand region of Madhya Pradesh who is a lakhpati (millionaire). He pulled it off by striking diamond from a 2-hectare shallow diamond mine adjacent to his farm field that he took on lease. People in Panna try their luck by taking annual lease of these mines. This time Yadav got a 12.93 carat diamond. As provisioned in the law, Yadav had to pay only 11.5 % of the royalty of the total price of the diamond fixed by the administration to get the diamond.
