Premier - Red Lake Discover New Gold Zones at East Bay

Download Press Release


PREMIER GOLD MINES LIMITED (TSX:PG) is pleased to announce that drilling at the East Bay Project in the Red Lake gold mining district of Ontario has discovered a potentially significant gold bearing system. The East Bay Project is located along the East Bay Trend to the north of, and on strike from, Rubicon Minerals Phoenix Gold Project, which has garnered considerable market attention for its F2 Zone discovery.

The East Bay project is one of two joint ventures Premier holds in the heart of the prolific Red Lake gold mining district in partnership with Red Lake Gold Mines Limited (“RLGM”), an affiliate of Goldcorp Inc. A portion of the East Bay Property is held 35% by Premier while the “Rivard Block”, adjacent to the new discovery, is held 50/50 with RLGM. The Rahill-Bonanza joint venture Project (Premier 49%) is located between the world class Red Lake Gold Mines complex to the east, and the Cochenour (Bruce Channel) complex to the west and will be subject to an upcoming summer drill program aimed primarily at delineating the recently discovered PG70 Zone.

During the winter of 2010, 5 holes were completed to test four targets based on the F2 Model and proximal to a major regional shear zone at the footwall of the East Bay Ultramafic Trend. Of the primary targets, where cross-cutting structures were interpreted to cut the East Bay Trend, one contained gold mineralization associated with a major mineralized shear zone. Due to ice conditions, several favourable structures remain untested. Hole EBJV10174, a single hole into the target, intersected high grade gold within a quartz vein containing visible gold as well as gold associated with a mineralized shear zone. Hole EBJV10175 tested the shear zone 500 m to the northeast and also intersected similar mineralization.


Highlights from the new discovery area include:

  • 51.04 g/t Au across 0.7 m (1.49 oz/ton across 2.3 feet) within the QV Zone
  • 7.25 g/t Au across 2.8 m (0.21 oz/ton across 9.0 feet) within the Shear Zone

The gold bearing system shares several similarities to the F2 Zone. The QV Zone is comprised of a quartz vein zone in biotite-altered porphyry containing 3% disseminated pyrrhotite and Visible Gold. The EBSZ is hosted within deformed, silicified basalt and biotite-altered porphyry on the footwall side (east) of the East Bay Serpentinite. The zone contains about 5% disseminated pyrrhotite. Figure 1 displays the location of the East Bay joint venture property. The partnership is considering a summer drill program at East Bay.

Tim Twomey, Exploration Manager for Premier, said, “The identification of significant gold mineralization associated with biotite altered porphyry on our East Bay project is similar to the primary gold zones at Rubicon’s F2 deposit. What’s truly exciting is that we have several kilometres of untested strike length as well as down-dip potential of this new discovery area”.

In addition to the Red Lake joint venture projects, Premier has five drills that will be active throughout the year on the Company’s Hardrock Project (Premier holds a 70% interest) where approximately 70,000 metres of drilling is planned. In 2009, drilling at Hardrock successfully identified multiple open pit and underground style gold zones. Recent drilling in the NN Zone intersected an impressive 22.97 g/t Au across 24.8 metres (0.67 oz/ton across 81.3 feet). This drilling is expanding on the recently announced a NI43-101 compliant resource estimate relating to the near-surface (open pit) zones at Hardrock. Premier expects to complete a revised resource estimate for both the near-surface and underground zones following the completion of the 2010 drill program.

PQ North Project

Drilling was recently completed on the Company’s 100% owned PQ North Property that is strategically located on the PQ limb of the key iron formation that is host to Goldcorp’s Musselwhite Gold Mine. Musselwhite produced 233,000 ounces of gold in 2009. Drilling at PQ North has discovered mineralized zones with gold grades and widths comparable to those at Musselwhite, within a near-identical geological setting. The furthest north intersection in the PQL Zone in 2010 returned 5.65 grams per tonne gold (g/t Au) across 3.0 metres (m), in PQ10032 from 687.0 m to 690.0 m. This has now outlined a continuous zone for a plunge length of 325 m that remains open down-plunge. Three holes tested the MA Zone in 2010 and returned up to 7.09 g/t Au across 1.0 m in PQ10028. Four holes investigated the East Limb of the iron formation for the first time and three of these returned anomalous results, up to 11.05 g/t Au across 1.0 m in PQ10025. The shape of this limb is now better understood and it contains excellent untested targets where the auriferous limb is intersected by vertical shear zones. These targets are expected to be tested in the next drilling phase.
