Grades at GOLDCORP’s Red Lake mine in northwestern Ontario only get richer. As if that wasn’t enough good news, a new high-grade gold zone has been unearthed.

The deeper that Goldcorp drills, the better the results. The existing High Grade Zone (HGZ) is now known to extended an additional 122 metres below the previous deepest intersection. This mineralization has been outlined to a total depth of 2,210 metres. Two of the most recent holes returned values of up to 251.7 g/t Au (a whopping 7.34 ounces per ton) over 4.27 metres. Delineation drilling in the HGZ has encountered 26 intersections in the hanging wall with an average grade of 389.2 g/t Au (an almost-unbelievable 11.35 ounces per ton) over 2.79 metres.

The newly-discovered high-grade area lies 2,286 metres below surface. The drillhole intersected 58.9 g/t Au over 3.32 m. The core came from the hanging wall, which lies parallel to and above the HGZ.

Mineralization in the Far East Zone is also returning significant assays. Holes there have cut wide zones with up to 23.3 g/t Au over 6.40 metres and narrow high-grade zones with up to 577.4 g/t Au over 1.22 metres. Goldcorp believes that this zone hosts mineralization of similar grade and structural controls as the Red Lake mine itself.
