Last week, Stornoway Diamond Corporation released the results of their latest drilling program at their Renard project (part of the Foxtrot property) in central Quebec. The dimensions of three diamond-bearing kimberlite bodies were expanded beyond those expected by the previous models.
Although the density of drill-holes is too low to properly resolve the bodies at depth at a resolution that is suitable to be deemed an indicated or even inferred resource under NI 43-101 standards, the upside is promising. Three drill-holes each were put into Renard 3, 4, and 65. These data increase the previously modeled dimensions of the kimberlite pipes. The maximum lower cut-off for Renard 3 was extended from the depth of 395m established in the existing NI 43-101 report to 439m. The same was done for Renard 4, going from 380m to 759m. No previous 43-101-compliant resource values existed for Renard 65, but drilling encountered kimberlite a a maximum vertical depth of 513m. One drill hole was also put into Renard 1 and further confirmed multiple lithologies and a maximum depth of 370m. The increase in tonnage for the project is not as large or as certain as with the reported increase in Renard 2 earlier this year, but it is substantial and unexpected (see above image of a geological model of R-4 with 3 drill-holes showing kimberlite outside of the modeled dimensions (PMD: potential mineral deposit).
Renard 65 (geological model above) stands apart from the other two bodies (R3 and 4) as it is entirely classified as PMD and cannot be included in the 43-101 feasibility study recently contracted out to SNC-Lavalin. R65 is quite large in terms of ore tonnage, but lower grade than other bodies. The body would potentially add to the mine life or throughput of ore at the mine as extra reserves, but not significantly affect overall mine grade or diamond valuation as it is believed to be one of the least economic bodies in the cluster. Renard 1 would be classified in the same group as 65. Also adding to the potential reserves at the future Quebec mine would be the 4+ km long Lynx dyke, and smaller Hibou dyke. However, the diamonds from these kimberlite dykes are typically more brownish in colour than the ones from the Renard pipes and thus have a lower average valuation (US$/c).
Stornoway’s increasing focus on Renard has left its other lower-stage targets on the back-burner. Aviat on the Melville peninsula in Nunavut is the next most promising after Renard. Though less-studied and containing smaller white diamonds, its high grade (~2c/t) and unknown extent holds significant potential. Completion of a mine at Renard should provide an income stream to fund the next necessary step of bulk sampling.
The only remaining project of relative significance held by Stornoway is its minority share in the Churchill kimberlite project operated by Shear Minerals. Although a portion of the project has attracted the attention of Rio Tinto, it appears to be doomed to languish as Shear Minerals has become preoccupied by its purchase of the Jericho mine and Stornoway’s lack of funds for non-priorities.
As of its last quarterly report, the company had $14 million in cash. From this, Stornoway must fund its 50% share of the upcoming Renard mine feasibility study (the other half belongs to SOQUEM). A secondary study is in the works to examine bringing hydroelectric power lines into the camp from the north. If possible, attaching the mine to the electric grid would occur a few years into the mine-life. The earlier pre-feasibility study from over a year ago assumed on-site electric generation. Access to Quebec’s cheap hydroelectricity would significantly lower operating costs and avoid vulnerability to high oil prices.
Given that the third generation of Canadian diamond mines (Renard, Fort à la Corne, and maybe even Gahcho Kue) are coming on-line in the next few years, diamond stocks are rising. A half-decade of disinterest and bad luck (see Tahera and Jericho) is hopefully over, and investors: individual and institutional, will begin to see the value in the long wait for a diamond mine to reach production.
