Goldstone operator drills 114 m of 7 g/t Au at Hardrock

2010-11-04 10:18 ET - News Release

Mr. Philip Cunningham reports

HARDROCK PROJECT DRILLING: BEST RESULTS TO-DATE

Goldstone Resources Inc. operator Premier Gold Mines Ltd. has delineated significant gold mineralization in multiple horizons at the Hardrock joint-venture project in Northwestern Ontario. There are currently 11 drill rigs operational on the property, testing for extensions of previously mined zones and exploring new target areas. Goldstone holds a 30-per-cent carried interest in the Hardrock project.

Recent highlights include:

  • 7.92 grams per tonne gold across 114.5 metres including 23.56 g/t Au across 31 m in hole MM179C conducting initial resource-confirmation drilling in the F zone;
  • 18.49 g/t Au across 20.5 m in hole MM170 located approximately 500 m west of the limits of previous exploration;
  • Recent exploration drilling has intersected strong mineralization in new areas on the property, and assays are expected in the near future.

"We have ramped up our drilling due to unparalleled success in multiple areas. Expansion of historically mined zones and multiple new discoveries are expected to add materially to the current gold resource at Hardrock," stated Ewan Downie, president and chief executive officer of Premier. "This continued success demonstrates the potential to define a multimillion-ounce gold deposit."

"We continue to be gratified by results at the joint venture with Premier, while aggressively pursuing drilling programs on our 100-per-cent-owned properties in the Geraldton-Beardmore camp, including the Key Lake property, contiguous to the Hardrock project," added Philip Cunningham, Goldstone chairman and interim CEO.

F-zone resource delineation

The F zone is the largest of the past-producing mine zones at Hardrock, which produced more than 1.4 million ounces utilizing bulk underground methods with widths often exceeding 30 metres. Importantly, when the mine closed in the 1960s, a 600-metre plunge length of ore was left unmined. Hole MM179C is the first of several holes to confirm this mineralization and upgrade it to NI43-101 resource standards.

The MM179C intersection includes eight metres of mine workings at zero grade, which is part of the developed openings within the F zone. True widths are estimated at approximately 60 to 70 per cent of intersection.

Western mine extension (F zone)

Recent drilling has intersected mineralization to the west of and below the limits of historical mining at Hardrock, which was mined to a maximum depth of 600 metres. This drilling is located in a previously untested area more than 500 metres to the west of the western-most mined area at Hardrock. Hole MM170, a step-out from previously released hole MM157, returned 18.49 g/t Au across 20.5 m, including 348 g/t Au across 0.8 m. Wedge drilling in this new area has been completed with assays pending.

Other Hardrock drilling

Drilling continues to delineate mineralization within the NN zone and the SP zone target areas, with results expected to be released in the future. Additionally, drilling is testing several new exploration target areas on the property, recently intersecting favourable structures and mineralization, including visible gold in multiple locations. Assays are pending. Follow-up drilling at these intersection sites is under way.

The Hardrock project is host to several past-producing mines, which collectively produced nearly three million ounces of gold from 1938 to 1968, primarily from shallow depths within 600 metres of surface (considered to be shallow for an Archean gold deposit). The Hardrock project benefits from development advantages with the TransCanada highway, TransCanada pipeline and major power lines running through the centre of the property. A revised resource calculation is expected to be completed following the 2010 drill program, containing both open-pit and underground-style mineralization.
