The Jericho Diamond Mine is a dormant diamond mine located in Canada's Nunavut territory. Jericho is Nunavut’s first and only diamond mine. It is located 420 km (260 mi) northeast of Yellowknife, Northwest Territories and is accessible by air all year and by winter road from Yellowknife. The project was mined from 2006 to 2008, and produced 780,000 carats (156 kg; 344 lb) of diamonds from 1,200,000 tonnes (1,200,000 long tons; 1,300,000 short tons) of kimberlite mined from the open pit operation. Over $200 million was invested in the development of the Jericho operations including the construction of a 2,000 t (2,000 long tons; 2,200 short tons) per day diamond recovery plant, maintenance facility, fuel farm, and offices and accommodation for 225 personnel.

On July 19, 2010 Shear Diamonds (née Shear Minerals Ltd) (TSX-V :  SRM), a diamond exploration company focused on the Nunavut region, announced its purchase of the Jericho Diamond Mine. [1] In late 2010, Shear announced that it would take about a year to devise a plan to reopen the mine. [2] Shear began processing the existing recovery reject pile in early 2012, selling the recovered stones to Belgian diamond firm Taché, [3] which provided a revolving line of credit. However, operations were suspended in September, as Shear, citing "limited funds and significant operations", has sought to minimize expenditures. Taché has given notice of default on certain covenants of their investment agreement, but is working with Shear to find funding or a purchaser. [4]

Operations

The mine was developed, opened and operated by Tahera Diamond Corporation. The company was provided with CAN $35 million loan by Tiffany & Co. to assist in construction of the site, as part of a marketing alliance. The mine produced diamonds from 2006 to February 2008, and was Tahera's only mining operation. The company reported financial losses in 2007 due to operational difficulties, the high value of the Canadian dollar, high oil prices, and the short operating season of the Tibbitt to Contwoyto ice road in 2006. Tahera filed for protection from creditors in January 2008, and the mine stopped recovering diamonds once existing ore stockpiles ran out, one month later.

There is no registered airport at the site, so all heavy equipment had to be brought in by the Tibbitt-to-Contwoyto winter road. Due to the remoteness of the site, the mine was part of the impetus for a proposal to build a port near the community of Bathurst Inlet with a road to both the Diavik Diamond Mine and the Ekati Diamond Mine.

Production

The mine was estimated to be able to produce 375,000 carats (75 kg; 165 lb) a year with a value of CAN $25 million. In the first half of 2006 the mine had processed 210,000 t (210,000 long tons; 230,000 short tons) for 126,918 carats (25 kg; 56 lb).

Canadian diamonds Sort of diamonds

Canadian diamonds are diamonds which have been mined in any one of the major Provinces and territories of Canada. Diamond-rich areas weren't commercially extracted in Canada until the early 1990s. Before that time, diamonds were only known by Indigenous communities. For the first 60 years of the 20th century, diamonds originated from kimberlite pipes and alluvial deposits in places such as Africa and some from South America. Later, diamond discoveries were made in the Soviet Union. Since the 1990s, major diamond discoveries were made and mining operations began. Canadian diamonds play a large role in the world market of diamonds.

Gahcho Kue Diamond Mine Diamond mine in Canada

Tibbitt to Contwoyto Winter Road is an annual ice road first built in 1982 to service mines and exploration activities in the Northwest Territories and Nunavut in Northern Canada. Between 400 and 600 km long, the road is said to be the world's longest heavy haul ice road and operates for eight to ten weeks starting in the last week of January. Most of the road (85%–87%) is built over frozen lakes, 495 km (308 mi), with the remaining 73 km (45 mi) built on over 64 land portages between lakes. The ice road was the location of the first season of Ice Road Truckers.

Mining industry of Ghana

The Mining industry of Ghana accounts for 5% of the country's GDP and minerals make up 37% of total exports, of which gold contributes over 90% of the total mineral exports. Thus, the main focus of Ghana's mining and minerals development industry remains focused on gold. Ghana is Africa's largest gold producer, producing 80.5 t in 2008. Ghana is also a major producer of bauxite, manganese and diamonds. Ghana has 20 large-scale mining companies producing gold, diamonds, bauxite and manganese, and, there are also over 300 registered small scale mining groups and 90 mine support service companies.

Mary River Mine Iron ore mine on Baffin Island, Nunavut, Canada

The Mary River Mine is an open pit iron ore mine on Inuit Owned Land (IOL) operated by the Baffinland Iron Mines Corporation (BIMC), in the Mary River area of Qikiqtaaluk Region, Baffin Island, Nunavut, in the Canadian Arctic Archipelago. As of 2021, Mary River mine operation consists of an open-pit mine, two work camps for hundreds of workers, a tote road—from the Mary River site to Milne Inlet—and a port infrastructure at Milne Inlet. According to a 4-year study published in 2008, the Mary River Mine, with its four massive iron ore deposits of 65-70% pure iron ore was "one of the most promising undeveloped iron deposits on the planet". It was not until technological advances were in place in 2010, and the market for iron ore had dramatically increased that sizable financial backing for the high cost of development in a remote region known for its inhospitable climate, was available. The mine began operations in 2014, and the first shipment to Europe arrived in 2015. Baffinland is currently planning on expanding the mine. In February 2021, a group of Inuit hunters blockaded access to the mine for a week to protest the expansion.

The Bathurst Inlet Port and Road Project is a plan to build an all-weather road from Bathurst Inlet in Nunavut to a complex of mines that are approximately equidistant between Bathurst Inlet and Yellowknife, NWT. There are no paved roads between Yellowknife and the mines, so they have relied on shipping supplies to the mines over winter-time ice roads. However, in 2005, there was a particularly warm winter, and the ice roads weren't safe for a long enough period to bring in supplies.
