Drilling to Focus on Expanding Deep Kerr and Discovering Additional Higher Grade Core Zones
TORONTO, June 10, 2014 /PRNewswire/ - Seabridge Gold reported today that exploration drilling has begun at its wholly-owned KSM project in Northwestern British Columbia, Canada. The primary focus of the program is to expand the 515 million tonne inferred resource averaging 0.53% copper and 0.36 g/T gold found last year at Deep Kerr and also increase its average grade. The second objective is to test several more identified and highly prospective core zone targets which have the potential for large, high grade deposits similar to Deep Kerr, including the Iron Cap deposit at depth.
Seabridge Chairman and CEO Rudi Fronk noted that "our understanding of the KSM system has increased immensely since the discovery of Deep Kerr, and the more we learn, the more upside we see. We now know a great deal more about the geophysical and geochemical signatures of the higher grade core zones we are looking for and we have also unraveled the major displacements that have occurred along the district's faults. With these powerful tools at our disposal, we are confident that we will find more core zones this summer. Both copper-rich and gold-rich targets are included in the program. We also expect to make substantial additions to the Deep Kerr resource."
Additional MT geophysical surveys have recently been completed by Quantec Geoscience Ltd of Toronto and are now being interpreted. MT (magnetotelluric), which measures fluctuations in naturally-occurring electrical and magnetic fields over a broad range of frequencies, has proven to be an effective tool for conceptual modelling of deep targets at KSM. MT resistivity profiles along the plunge projection of the original Kerr deposit helped to guide the discovery of Deep Kerr. The same method is being used to identify other potential core zones.
The initial targets in the 2014 program are:
Deep Kerr confirmed the existence of higher grade core-zone-style mineralization at KSM. The Deep Kerr opportunity is enhanced by its accessibility from the Sulphurets valley floor by way of an inclined tunnel, raising the potential for a lower cost block caving option which would also have significant environmental benefits. The last drill holes completed in 2013 at Deep Kerr, located on the north end of the deposit, were some of the widest and richest to date. One of the priority targets for 2014 is to determine the northern extension of the deposit with step-outs that could extend the strike of Deep Kerr by several hundred meters.
Deep Kerr demonstrates that the vertical zonation of a major porphyry system remains intact at KSM. Growing evidence suggests that the lateral geometry may also have been preserved at Deep Kerr. The standard model for very large porphyry mineral systems such as Bingham Canyon in Utah is a symmetrical distribution of metal around a source intrusion. In this model, the core of the source intrusion has typically pushed its metal load out to the margins. On the margins, a systematic zonation of metals is observed consistent with changing fluid conditions related to changing pressures and temperatures as the fluids move away from the source stock. If this model applies to Deep Kerr, it would mean that the Deep Kerr resource drilled to date may only be the western limb of the mineral deposition surrounding the host intrusion and that an eastern counterpart has yet to be found. Such a discovery would be significant, potentially repeating the known Deep Kerr deposit in addition to the expected expansion of the west limb to the north.
Ongoing analysis of the data from the original Kerr deposit suggests the potential for an eastern limb to Deep Kerr. Geophysical surveys from 2011 indicated that the eastern part of the Kerr system contained rocks with physical properties similar to the Deep Kerr zone. This interpretation also appears to be supported by the new MT surveys. An eastern extension of Deep Kerr is therefore a second target for this year's program.
A third target at Deep Kerr is derived from mineralogical data which points to the potential for greater concentrations of bornite, a mineral with higher copper content, below the limits of last year's drilling. This target remains a priority for testing.
Drilling below the Iron Cap deposit in 2012 and 2013 attempted to test the downward plunge of the deposit for higher grade gold-copper core zone mineralization. Promising results were obtained in these drill holes, particularly IC-13-49, which returned 261.4 meters of 0.40% copper and 1.09 g/T gold. Targeting this zone by drilling down plunge is not optimum; consequently, holes in the 2014 program have been designed to cut across the projected core zone at Iron Cap to determine the width and strike of the zone. Iron Cap is currently designed as an underground block cave mine, sitting about 1000 to 1200 meters laterally from the access tunnels designed for the KSM project. Extending this deposit down plunge into higher grade gold and copper zones would significantly improve the Iron Cap deposit with little change to the KSM project design.
"The Seabridge exploration team believes the 2014 program will be our best yet. The excitement level is really palpable as the drilling begins," Fronk said.
The KSM Project represents a mining district hosting multiple deposits and containing one of the largest undeveloped gold and copper reserves in the world. Its composite intrusive complex hosts four known, large, gold-copper porphyry deposits which occur within the upper portion of the system and have demonstrated vertical continuity down to near-magmatic bornite-bearing core zones and upward through voluminous mineralized stock works into near surface epithermal vein deposits. This vertical zonation is typical of many of the world's largest mining districts. Deep Kerr is the initial confirmation of the existence of deep core zones beneath the porphyry deposits, which this model predicts. Core zones are typically formed under higher temperature and pressure conditions, resulting in a mineralogical character usually associated with significantly higher metal content.
Exploration activities at KSM are being conducted by Seabridge personnel under the supervision of William E. Threlkeld, Senior Vice President of Seabridge and a Qualified Person as defined by National Instrument 43-101. Mr. Threlkeld has reviewed and approved this news release. An ongoing and rigorous quality control/quality assurance protocol will be employed during the 2014 program including blank and reference standards in every batch of assays. Cross-check analyses will be conducted at a second external laboratory on 10% of the samples. Samples will be assayed using fire assay atomic adsorption methods for gold and total digestion ICP methods for other elements.
Seabridge holds a 100% interest in several North American gold resource projects. The Company's principal assets are the KSM property located near Stewart, British Columbia, Canada and the Courageous Lake gold project located in Canada's Northwest Territories.
