Seabridge grows its Deep Kerr gold-copper resource.

Seabridge Gold has reported an updated mineral resource estimate for the Deep Kerr gold-copper deposit at its 100% owned KSM project in northwest British Columbia, Canada, that increases the deposit's inferred resource to 1.01 billion metric tons (mt) grading 0.35 g/mt gold and 0.53% copper. Contained metals total 11.3 million oz of gold and 11.8 billion lb of copper.

Seabridge discovered Deep Kerr in 2013, and the deposit is adding resources to the already huge KSM project, which currently has proven and probable reserves of 38.2 million oz of gold and 9.9 billion lb of copper. Regarding Deep Kerr, Seabridge Chairman and CEO Rudi Frank said, "The size of the deposit continues to grow with no diminishment of grade. Furthermore, we have not yet found the limits of the Immense mineralizing system that created Deep Kerr.

The drillhole database used to estimate the Deep Kerr mineral resource consisted primarily of data collected by Seabridge from 72 core drill holes totaling more than 67,000 m.

Seabridge has retained Golder Associates to undertake bulk underground mining studies for Deep Kerr.

Seabridge also is updating the 2012 preliminary feasibility study (PFS) prepared for the overall KSM project, with completion scheduled for later this year. The updated PFS will restate mineral resources for all of the zones at KSM, using both open-pit and block-cave mining methods to constrain the resources. It will also include changes to key input parameters since 2012, including metal prices, currency exchange rates, labor rates, and energy costs. (
