Kirkland Lake region target of diamond exploration; Dianor Resources encouraged by diamond find in northeast.A Quebec-based diamond exploration company has identified diamond indicators on its property near Kirkland Lake Kirkland Lake, mining town, E Ont., Canada. An important gold-mining center, gold was discovered there in 1911 and again in the 1980s at Harker. The mining of iron ore and tourism are two other important industries. .
With its drilling campaign complete, Dianor Resources has identified three sets of kimberlite kimberlite: see diamond.

Though still evaluating and plotting the data, company president John Ryder John Ryder (c.1697–1775), was the Church of Ireland Bishop of Down and Connor, 1743–1752, and Archbishop of Tuam, 1752–1775. He was a noted alumnus Charterhouse School. is encouraged by the drill results to date in his search for diamonds in northeastern Ontario Northeastern Ontario is the region within the Canadian province of Ontario which lies north and east of Lakes Superior and Huron.
Northeastern Ontario consists of Algoma District, Sudbury District, Cochrane District, Timiskaming District, Nipissing District, Manitoulin .
"We're encouraged by the last drill hole (P12) where the intersected width is over seven feet," says Ryder.

Dianor was the first company to recover a diamond in the James Bay James Bay, shallow southern arm of Hudson Bay, c.300 mi (480 km) long and 140 mi (230 km) wide, E central Canada, in Nunavut Territory between Ont. and Que. Numerous rivers flow into the bay; many of these have been developed for hydroelectric power in Quebec (see region of Quebec, recovering a yellow microdiamond from a 13.6-kilogram sample collected from a lamprophyre lam·pro·phyre

This year, Dianor has been gradually increasing its presence in Northern Ontario Northern Ontario is the part of the province of Ontario which lies north of Lake Huron (including Georgian Bay), the French River and Lake Nipissing.
Northern Ontario has a land area of 802,000 km² (310,000 mi²) and constitutes 87% of the land area of Ontario, although it . Last January, the company signed an agreement with some prospectors to acquire 22 claims scattered over many townships north of Matachewan, totalling 11.5 square kilometres, which they have dubbed the Cluster project.
The company is still awaiting results from this past year's program of ground-magnetic surveys, soil sampling and a reverse-circulation drilling program last spring to search for diamond indicator materials from the glacial till.
The claims are situated in what is considered the Larder Lake and the Porcupine porcupine, in zoology

In August, Dianor signed an option agreement with Globex Mining Enterprises to acquire a 100-per-cent interest in the diamond potential on the Pacaud Township property near Kirkland Lake.
This fall, Dianor also acquired an option to earn an interest in the Abitibi Extension Project from * Eastmain Resources Inc. The agreement is for an area north of the Cluster project.
Ryder says Dianor plans to work on both Cluster and Pacaud projects simultaneously. The company has already spent $200,000 on exploration in northeastern Ontario this year.
On Pacaud, previous drilling work was done for gold in the late 1970s, and there are rumours abound that some of the unusual rock found back then helped kick-start the early diamond exploration rush in Ontario.

"We're excited because there are three different sets of kimberlites on a very small part of the property."
One set is magnetic, which can be followed on surface by instrument for up to 150 metres.
"That indicates these dykes have distance and length.

Dianor's plans for this winter are to conduct ground magnetic work to determine the geometry of the dykes and see how extensive they are before initiating a shallow drilling program next spring to evaluate the size and potential of the dykes.
If his venture proves successful, Ryder has no doubt a diamond mine could dramatically improve the area's economy overnight.
"A diamond mine is worth billions of dollars. It's very environmental friendly compared to other types of mining; there are no noxious substances used. It's basically like a rock quarry operation."
Ryder remains encouraged by the abundance of diamond exploration activity in the North, including Sudbury Contact Mines' bulk sampling of a kimberlite in the New Liskeard area, De Beers considering setting up an office in Timmins to service its Victor project and Metalex Ventures discovering a kimberlite at its Attawispiskat diamond project.
The thick overburden in the area of more than 100 feet in places can be a major technical difficulty for junior companies to explore, says Ryder.
"However, we believe with the system we've developed with all our work in James Bay, Quebec for the last 18 months, we have a method we can apply to that to cut our costs in evaluating them."
