PREMIER GOLD MINES LIMITED (TSX:PG) is pleased to announce that deep drilling has intersected multiple high-grade gold zones below the bottom level of the historically mined North Zone at the Hardrock Project in Northwestern Ontario. Highlights include an intercept of 39.20 grams per tonne gold (g/t Au) across 4.8 metres (m) or 1.14 oz/ton across 15.7 feet (ft) . This hole has confirmed that the North Zone deposit is wide open at depth, with intersections as deep as 40 metres below the historic workings. Additionally, final work is being done in advance of releasing an initial NI43-101 resource calculation for Hardrock on open pit style deposits.
North Zone Deeps
The first hole drilled to test the down-dip potential of the mine, MM050, has intersected multiple zones of high-grade gold mineralization immediately below the mined portion of the North Zone.
Significant intercepts include:
- 39.20 g/t across 4.8 m (1.14 oz/ton across 15.7 ft) from 662.7 m to 667.5 m
- 3.65 g/t Au across 3.0 m (0.11 oz/ton across 9.8 ft) from 681.0 m to 684.0 m
- 4.03 g/t Au across 6.9 m (0.12 oz/ton across 22.6 ft) from 703.9m to 710.8m
- Includes 7.90 g/t Au across 2.6 m (0.23 oz/ton across 8.5 ft) from 703.9m to 706.5m
Additional drilling to test the extension of the North Zone continues to intersect multiple mineralized zones including a broad mineral-rich section down dip from hole MM050. Figure 1 below, a 3D longitudinal section of the Hardrock Project highlighting hole MM050.
The North Zone was previously mined to a depth of 2,000 feet (610 m) with production of 2.97 million tons at a recovered grade of 0.22 oz/ton (7.54g/t Au). Mining in the West Zone, a part of the North Zone horizon, resulted in the extraction of 532,254 tons with a recovered grade of 0.23 oz/ton (7.85 g/t Au). Premier has completed a second deep hole, MM079, from which several wedge holes are planned to further define the depth potential of the North Zone.
Ongoing work at Hardrock is testing both open pit and underground type targets. Several potential open pit zones have been delineated to be included into a NI43-101 compliant resource calculation which is expected to be completed in Q4 2009 (initial open pit resource). The focus of drilling has now shifted towards defining underground-style zones that will be included in an updated resource that is expected in Q3 2010.
Significant potential exists for developing resources in several areas including:
- Open pit-style mineralization in the main areas, the Tenacity, EP (includes NN) and Kailey Zones. Significant results to-date include: 15.97g/t Au across 32.1 m and 4.13 g/t Au across 18.9 m in the Tenacity Zone; 5.2 g/t Au across 37.0 m and 19.0 g/t Au across 11.3 m in the EP Zone; 6.4g/t Au across 22.4 m and 52.9 g/t Au across 7.9 m in the NN Zone; and 1.47 g/t Au across 162.0 m and 2.16 g/t Au across 92.2 m in the Kailey Zone.
- Underground-style mineralization in the SP Zone where drilling has returned numerous significant intercepts including 6.6 g/t Au across 32.6 m and 9.7 g/t Au across 11.8 m.
- New high-grade vein targets, including the HGN discovery where recent drilling has intersected significant visible gold with intercepts that include 1,141.5 g/t Au (33.3 oz/ton) across 2.0 m and 49.8g/t Au across 6.0 m.
- Historical resource blocks that remain within the mine workings and the main mined zones which remain open below the 13th level (610 m below surface) as tested by hole MM050.

The Hardrock Project is operated under a joint venture with Roxmark Mines Limited (TSX-V:RMK) (Premier earning a 70% interest). The Hardrock Project is host to several past-producing mines which collectively produced nearly 3.0 Million ounces of gold primarily from relatively shallow depths (600 metres) 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.

Premier Gold Mines Limited is a well-financed Canadian-based mineral exploration and development company with several active projects and deposits in Northwestern Ontario. In the Red Lake gold mining camp, two projects are operated in joint venture with Red Lake Gold Mines, an affiliate of Goldcorp Inc., and another, adjacent to the Red Lake Gold Mines complex, is operated on a 100% basis. The company also owns a 70% interest in the Hardrock Project, an advanced-stage gold project in the Geraldton area.
