Reports New Discovery at Hardrock Project, Provides Mid-Year Update

TORONTO, ONTARIO--(Marketwire - June 29, 2011) - Goldstone Resources Inc. (News - Market indicators) (PINK SHEETS:GRSZF) today announced that drilling at the Hardrock Project joint venture by Premier Gold Mines Limited (TSX:PG) as operator has discovered a new zone at Tenacity South with confirmed high-grade mineralization in hole HR054 up to 10.89 grams per tonne gold (g/t Au) across 10.0 metres (m) (0.32 oz/t across 32.8 feet) including 45.40 g/t Au across 2.0 m (1.33 oz/t across 6.6 feet), and hole HR053 intersections of 37.49 g/t Au across 2.1 m.

Earlier in 2011, Goldstone and Premier released a NI43-101 compliant gold resource estimate for the Hardrock Project. Numerous zones remain wide open for expansion and the western-most hole drilled to-date (MM170) intersected 18.49 g/t Au across 20.5m or 0.54 ounces per ton (oz/t) across 67.2 feet.

Ongoing 2011 drilling has realized numerous successes that are expected to add materially to the current resource. Expansion of the SP and F Zones, more recently identified horizons including the P and K Zones, and new discoveries including the Tenacity South Zone auger well for the future economics of the project. Other highlights from the 2011 drill program include:

• Expansion drilling in the SP Zone with intercepts up to 11.25 g/t Au across 8.2 m and 6.02 g/t Au across 15.0 m

• Further expansion of the F-Zone deposit with intersections of up to 6.97g/t Au across 5.0 m

• Continued success in the recently discovered K-Zone with new assays of up to 10.16 g/t Au across 3.1 m

• Several returning high-grade vein style mineralization within the main porphyry unit (P Zone) with intercepts as high as 7.15 g/t Au across 6.0 m.

"We continue to very optimistic about the development potential of the Hardrock Project, " said Goldstone Chairman and Interim CEO Philip Cunningham. "We also believe our adjoining, 100-owned Key Lake property, for which we announced latest drilling results this morning, will benefit from its proximity to Hardrock."

Stephen McGibbon, P. Geo., is the Qualified Person for the information contained in this press release and is a Qualified Person within the meaning of National Instrument 43-101. Assay results are from core samples sent to Activation Laboratories, an accredited mineral analysis laboratory in Ancaster, Ontario, or to Accurassay Laboratories, an accredited mineral analysis laboratory in Thunder Bay, Ontario, for preparation and analysis utilizing both fire assay and screen metallic methods.

Hardrock Deposit

The Hardrock Project is located approximately 4 kilometres south of the town of Geraldton, Ontario and is host to several past-producing mines which collectively produced more than 3 million ounces of gold from depths primarily within 600 metres of surface between 1938 and 1968. Underground resources are located proximal to and below the historic mine workings. New discoveries including the High-Grade North Zone and the F2 East Zone will be the focus of the planned underground drill program. The current Mineral Resource estimate uses 11 identified mineralized domains to develop a combination potential open pit and underground mineral resource. The Hardrock Project benefits from development advantages with the Trans-Canada Highway, Trans-Canada Pipeline, and major power lines running through, or in close proximity to, the Project site. Significant services and a skilled labour pool exist with several communities located within 30 kilometres. Goldstone holds a 30% carried interest in the Hardrock Project

In April 2011, Premier announced an updated NI 43-101resource estimate for the Hardrock Project in the Geraldton area of which Goldstone has a 30% interest. The camp is host to several mines which historically produced more than 4.1 million ounces of gold from high grade ore—before being shut down primarily as a result of a $35 gold price—and to Goldstone's fully permitted, expandable 200-TPD Northern Empire mill.
