Kimberlites and Diamonds of Western Canada

Posted by David

This year’s GeoCanada conference and related workshops saw some attention to diamonds and kimberlites. Specifically those located in the western Canadian sedimentary basin (WCSB), covering Alberta and Saskatchewan.

The two main kimberlite clusters in this region are the well-known Fort a la Corne (FalC), and the lesser known Buffalo Head Hills (BHH) occurrences. The former cluster is in Saskatchewan and has been the focus of a major JV between Shore Gold (operator) and Newmont, the background of which was discussed in previous KIM Report posts. On the technical aspect of things, Shore Gold has done a lot of work in characterizing the complex structure of their two most economic kimberlite pipes: Orion South and Star (both are ~100 Ma). These pipes are composed of multiple units each formed during a separate volcanic eruption millions of years ago on the margins of an ancient shallow inland sea that covered most of what is today called the Great Plains. There are at least five  main units: Pense, Viking, Early Joli Fou, Late Joli Fou, and Cantuar (see the 3D model of the Star kimberlite below: different colours represent different petrological units). These units each erupted at a different time over many thousand of years, and differ in petrology, diamond grade and diamond size distribution. To further complicate things, these eruptions occurred over a timespan during which the inland sea was alternately expanding and contracting. The effect of these sedimentary processes (e.g. erosion, transportation, deposition) on the erupted kimberlite material led to the concentration of diamonds in some rock units and the removal of diamonds from others.

The other less-studied cluster is the ~65-85 Ma BHH in Alberta. Both barren and diamond-bearing pipes occur, also with variable geology and diamond grades as with the FalC pipes, although the extent of the complexity is unknown. The highest grade pulled from a BHH sample so far is close to 0.9 c/t (K252). Most of the pipes are a JV between Canterra Minerals Corporation (TSX.V-CTM; 28.5%, operator), Shore Gold (28.5%), and EnCana Corporation (43%). Shore Gold and Canterra each carry 50% of the operating costs. Canterra is the result of the business arrangement between Diamondex Resources Ltd. (TSX.V-DSP) and Triex Minerals Corporation (TSX.V-TKM) in 2009. Diamondex and Shore Gold bought their shares in a deal with Stornoway Diamond Corp. back in 2007. They later purchased another 12% from Burnstone Ventures Inc. (CNSX-BVE, formerly Pure Diamonds). A smaller subset of diamond-bearing pipes has been discovered by Grizzly Discoveries Inc. (TSX.V-GZD). These kimberlites: BE-02 and BE-03, are in the southeast region of the BHH cluster, previously thought to be barren. Grizzly also owns interest in a couple of much smaller diamond plays to the ENE in the Birch Mountains area of Alberta, as does Shear Minerals.

A couple of other companies have diamond interests in the WCSB: Vaaldiam Mining Inc. (TSX-VAA – Candle Lake, Saskatchewan) and Forest Gate Energy (TSX.V-FGE, formerly Forest Gate Resources – Fort a la Corne, Saskatchewan). However, activity on these properties has been fairly light (see map image of kimberlites in the WCSB below).

Both the BHH and FalC clusters were initially discovered by activities relating to energy exploration – petroleum and uranium, respectively. The BHH pipes were discovered by re-evaluating aeromagnetic survey maps that had classified the anomalies caused by the pipes to be well-heads for the oil fields that clutter the region. Some diamonds from these pipes have even been found to be coated with petroleum when recovered. The FalC cluster was found during aeromagnetic surveys. These pipes are located under 80-100 m of gravel, sand, and clay.

Though in comparison to other diamond mining regions (e.g. the Northwest Territories or the Otish Mountains in Quebec) current grade numbers are rather low, diamond valuations that do exist (only from FalC at this point) are higher than average for Canadian kimberlites. Access to infrastructure is also better, particularly when compared to Arctic kimberlites. This bolsters the revenue $/t kimberlite coming from those pipes. The main hurdle with this is the geological complexity of the FalC (and to a lesser extent BHH). Overcoming this problem has taken Shore Gold and the previous owners of the FalC pipes the better part of 20 years to overcome with exhaustive drilling and geophysics. The amount of detail given in recent reports indicates that their geology and diamond characteristics are becoming less vague, at least for the Orion South and Star bodies. Now having more information where and how rich the higher-grade zones are at Orion and Star, have allowed Shore Gold (and Newmont) to almost finalize their mine plan. Mr. George Read, Shore Gold’s senior VP exploration and development, confidently expects a full net profit after all costs and taxes of ~$25/t (CAN) ore from the project as it stands. The 50+ other kimberlite pipes remaining at FalC, along with those at BHH represent possible future resources for Shore Gold and its partners beyond the two currently gearing up for production.

On an ending note, Shore Gold reported re-valuation (April 2010) of the diamond parcels it had originally sent out and had valuated in March 2008. Price increases (in US$/c) since then are 10-20% higher for every parcel. What to keep in mind here is how the American dollar (what the revenues come in) fares against the Canadian dollar (what the costs come in). Over the past two years, the exchange rate has fluctuated from about $1 (US) buying $0.98 (CAN) to $1.30 (CAN). How much of that price increase is due to supply/demand and not currency adjustment is uncertain.

Government Spending Supports Canadian Mine Development

Posted by David

Background

At the 2009 PDAC convention this month, CEO and President Matt Manson of Stornoway Diamond Corp. commented that this current economic environment and resultant government plans to increase spending is good for companies trying to develop mines in the sense of available infrastructure. Mr. Manson was in particular referring to Stornoway’s Renard diamond project in the Otish Mountains of central Quebec. The pre-feasibility study released last fall made the assumption that the current winter road access available to the potential mine site would be upgraded to an all-season paved road by the time construction would commence. This was discussed to in the earlier KIM Report article covering the findings of this study.

The News

Good news came last Monday, when announced in Quebec’s 2009-2010 budget was $698 million for the development of roads in northern Quebec. Included in this allotment is money for the Route des Monts Otish (Route 167 Extension) that will extend from Chibougamau to the Renard site intersecting several other (metals) projects along the way (Eastmain, Strateco, and Western Troy). Details of the road project (in French) can be found on the government of Quebec website.

The Ramifications

This boon comes at a time when investors are showing little of the patience necessary to see out a diamond project develop into a mine. Although not as large as Ekati or Diavik, Renard is still of significant size, especially when the nearby Lynx and Hibou dykes (bulk sampling near completion) are considered. The main advantage Renard has is that it is not an Arctic diamond mine, but that it is located in central Quebec, within close proximity to infrastructure (closer now with this announcement). It will have much lower mining costs as compared to isolated projects.

Further Infrastructure Spending?

There still remains the potential for electric power to be brought in to the region, as power lines run only tens of kilometres away from the site, but no announcement has been made regarding this as of yet. However, the pre-feasibility study assumed that the mine would operate using electricity generated on site and with oil above US$100. At this point, considering the assumptions made by AMEC in conducting the study, any other additional infrastructure forthcoming is just gravy.

The long and winding road to a Quebec diamond mine

Posted by David

Stornoway Diamond Corp. (TSX-SWY) saw a 24.14% jump in stock price today, up seven cents to $0.36/share. The rise followed the resumption of trading following a halt this morning due to a financing-related news release. SWY reported that they have received $22 million from a private placement of 24,444,444 common shares at ninety cents a share. This is a premium of 195% on top of the opening price of $0.305 today. The participants in the private placement are Agnico-Eagle Mines Ltd. (TSX-AEM) and Lorito Holdings Ltd. This $22 million will go to pay off debt in the form of debentures held by AEM and Lorito. AEM is already a significant shareholder of SWY, and with this transaction they will hold 17.6% of the outstanding shares. After the completion of this transaction, SWY will be debt-free.

 

This transaction is something of a coup in the current market. Juniors have been struggling to obtain funds to develop their projects and pay off debts. The credit market has been mostly deaf and blind to the woes of these companies as many lenders are themselves finding it a struggle to remain solvent. For a mining and exploration junior to pull off a private placement at a pre-subprime crisis share price is something of a shock (albeit a pleasant one) to investors and analysts who have become used to seeing the market cap of companies such as SWY slide by fifty to eighty percent. By offering equity to pay off its debts, SWY has managed to find a creative alternative to solving its cash problems in a bear market. The main upside here is that the dilution of the stock is one third of that if SWY were to issue stock at market price.

 

Now with balanced books, SWY faces only one major and immediate hurdle – to finance the construction of a diamond mine on their Foxtrot property in Quebec. This project, focusing mainly on the Renard kimberlite pipes, but also the Lynx and Hibou kimberlite dykes nearby, is joint owned 50/50 with SOQUEM and is fully described in an earlier article. SWY’s share of the mine construction costs will likely be over $100 million. The actual numbers are due out in September with the pre-feasibility study. The report was initially due this summer, but similar projects submitted earlier by Peregrine and Shore Gold tied up AMEC, the company contracted to conduct the study, until recently. Should the report be positive, as the geology and current diamond prices suggest, a significant amount of capital investment must be made to bring in the needed infrastructure for a mine. SWY will have to carry at least 50% of these costs.

 

Immediate of these costs is road access. Renard will not be an arctic diamond mine, dependent on airlifts and unpredictable ice roads for supply, but rather a site accessible by land year round. SWY is in talks with Western Troy Capital Resources Inc. (TSX.V-WRY), Strateco Resources Inc. (TSX-RSC), and Eastmain Resources Inc. (TSX-ER) – other mineral/metal exploration companies with projects in the Otish Mountains, local communities, and the Quebec government to build the “Route Monts Otish”. This partnership would provide strong benefits for all parties involved by sharing the cost of construction. SWY will need to bring September’s report to the table when the parties decide who pays what share of the road costs. It is also possible that the construction will bring in electricity service as well, further reducing the large bill SWY faces.

 

After September, SWY will have to come to a decision on how to fund the mine. Even if the Quebec government pays its full 50% share and the aforementioned road plan comes through, the cost to SWY will be well into the tens of millions of dollars. The company has a number of options to consider in obtaining the cash necessary to build the mine:

 

(1) They can go the traditional route and get financing from credit institutions. If the credit market simmers down by the winter this may be a possibility. Factors that would attract a lender are that the company has settled its accounts, the Foxtrot property has high and fairly well established diamond potential, and the company has many other promising secondary properties such as Aviat and Churchill (the latter a JV with Shear Minerals).

 

(2) Future private placements can be made. This will dilute the stock, but by how much is dependent on how the share price is doing at the time of issue. If today’s rise in share price is any indication, a positive report in September may be the catalyst investors need to return the company to the ~$1.00 level. In addition, management has established that they possess some expertise in brokering strong deals with large investment players (Rio Tinto is another major shareholder, with ~11% of the company).

 

(3) The company may bring in a third party to purchase a portion of their share in exchange for funding most of SWY’s costs a la the Franco-Nevada strategy.

 

(4) Interested parties could be sold secondary assets in exchange for cash to fund the mine. In addition to the aforementioned Aviat and Churchill projects, SWY holds promising advanced and reconnaissance stage projects in Nunavut, Ontario, the Northwest Territories, Alberta, and Saskatchewan.

 

It is likely the company will use a mix involving one, some, or even all of the above options to in order to proceed with construction.

 

Given that Quebec is regularly acclaimed as one of the top mining-friendly provinces in Canada, and that the province has a direct stake in the project, there seems to be fewer speedbumps on the road to Renard. Management with have to use every means at their disposal in order to navigate markets wracked with investor apathy towards diamond players.
