PREMIER GOLD MINES LIMITED (TSX:PG) is pleased to announce successful ongoing delineation of high-grade gold mineralization in multiple zones at the Hardrock Project in Northwestern Ontario. Highlights from recent drilling include extensions of the SP Zone down-plunge and significant step-out intersections in one of the primary resource targets, the NN Zone:

  • Drilling has defined several lenses within the SP Zone over a plunge length of some 1,100 metres with recent step-out holes returning up to 11.69 grams per tonne Gold (g/t Au) across 6.7 metres (m) — or 0.34 ounces per ton (oz/t) across 22.0 feet and 9.09 g/t Au across 12.3m (0.27 oz/t across 40.3 feet).
  • Drilling at the NN Zone has expanded near-surface mineralization with open-pit style intersections of up to 8.14 g/t Au across 9.0m (0.24 oz/t across 29.5 feet) at depth. Drilling in the NN Zone is now focusing on testing for higher-grade, underground style mineralization and has returned intersections of up to 15.09 g/t Au across 3.8 m (0.44 oz/t across 12.5 feet) up to 100 metres down-plunge from previous drilling.
  • Expansion drilling at depth in the historically mined North Zone has confirmed additional high-grade mineralization with intersections a further 100 metres down plunge returning multiple zones and assays of up to 10.97 g/t Au across 3.7m (0.32 oz/t across 12.1 feet).
“Drilling at Hardrock is delivering strong results in multiple zones and, with continued success, has the potential to materially add to our current resource. After only one year of drilling, we presently have 1.2 million indicated ounces of gold as well as 1 million inferred ounces, using a 0.6 gram cut-off with no capping.” stated Tim Twomey, Exploration Manager for Premier. “This is an impressive rate of discovery”.

NN Zone

Recent drilling in the NN Zone validates potentially open-pit style mineralization, along strike and at depth below the previously announced NI43-101 resource at Hardrock. Current drilling in the NN Zone is focused on delineating narrower, underground style resources, and has successfully extended the zone a further 100 metres down plunge with multiple high-grade intersections.

Highlights include 15.09 g/t Au across 3.8 m (0.44 oz/t across 12.5 feet) in the underground target area 100 metres down-plunge from previous drilling and 8.14 g/t Au across 9.0m (0.24 oz/t across 29.5 feet) approximately 100 metres down-plunge from previously announced hole MM117 that returned an impressive 22.97 g/t Au across 24.8m (0.67 oz/t across 81.4 feet).

Follow-up drilling down-plunge continues to intersect mineralization within the NN Zone. New drill results from the NN Zone are contained in Table 1.

SP Zone

Drilling in the SP Zone has now intersected high-grade gold mineralization over a plunge length of approximately 1,100 metres with new results of up to 11.69 g/t Au across 6.7m (0.34 oz/t across 22.0 feet). This drilling is expanding on previously announced intersections that included 15.68g/t Au (0.46 oz/ton) across 3.4m (0.46 oz/t across 11.2 feet), 6.60g/t Au across 32.6m (0.19 oz/t across 107.0 feet), and 17.14g/t Au across 7.0m (0.50 oz/t across 23.0 feet) down-plunge from the historically mined SP Zone.

The SP Zone was partially mined in the upper levels at Hardrock with 264,354 tonnes (291,428 tons) of ore extracted at an average grade of 8.37g/t Au (0.244 oz/t). Intermittent historic drilling that tested the unmined down-plunge extension of the SP Zone suggests the potential to outline mineralization over a plunge length of nearly 3.0 kilometres (8,500 feet).

New drill results from the SP Zone are contained in Table 2.

North Zone Deeps

One drill is focused on expanding mineralization below the bottom level of the Hardrock Mine in the historically mined North Zone. Hardrock was mined to a depth of 600 metres, shallow for an Archean gold deposit, and remained open at the time of closure. The new drilling is located approximately 100 metres down plunge from previously announced intersections that included 10.05 g/t Au across 24.2 m (0.29 oz/ton across 79.4 feet) in hole MM079B and 7.59 g/t Au across 23.3 m (0.22 oz/t across 76.4 feet) in hole MM092A. New drill results from the North Zone Deeps are contained in Table 3.

The Hardrock Project is operated under a joint venture with Goldstone Resources Inc. (TSX:GRC) (Premier holds a 70% interest in the project). The Hardrock Project is host to several past-producing mines which collectively produced nearly 3.0 Million ounces of gold primarily from shallow depths within 600 metres of surface from 1938-1968. The Hardrock Project benefits from development advantages with the Trans-Canada Highway, Trans-Canada Pipeline, and major power lines running through the center of the property. A revised resource calculation is expected to be completed following the 2010 drill program containing both open pit and underground style resources.
