Goldbrook Discovers Echo One-A New Ni-Cu-PGE Sulphide Zone; DDH ECH10-004 Intersects 6.89 metres 1.41%Ni, 1.03%Cu and 8.33 g/t PGE+Au

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Oct. 22, 2010) -


Goldbrook Ventures Inc. ("Goldbrook" or the "Company") (TSX VENTURE:GBK) is pleased to announce the first results from its 2010 Raglan project diamond drilling program. The Raglan Project located in Ungava, northern Quebec, is an Option-Joint Venture Agreement with Jilin Jien Nickel Industry Co., Ltd. ("Jilin Jien") of Panshi, Jilin, China.

Echo One Prospect

Goldbrook is pleased to announce the discovery of a significant and apparently extensive sulphide system at the Echo One prospect located between Goldbrook's Timtu and Bravo deposits.

The Echo Ultramafic Complex was identified as an under-explored and high priority target during 2010 pre-season targeting. Historical trenching and limited shallow drilling by previous operators had sampled narrow intervals of high grade Ni-Cu-Pd sulphides associated with a strike-extensive gossan at Echo One.

During the 2010 drilling campaign, Goldbrook completed 32 diamond drill holes totalling 6193 metres on the Echo One prospect. These holes were drilled on sections along the southern contact of the Echo One complex over a strike length of 1600 metres. One hole was lost due to permafrost conditions and 31 of these drillholes have intersected sulphide mineralization located both within, and at the contact of, a large composite ultramafic complex. Samples from all mineralized intervals have been submitted to ALS Laboratory Group in Vancouver and results are pending. This release reports lab assay data for the first eight drillholes, drilled on sections covering 450 metres strike extent of the Echo One Complex.

Drilling to date demonstrates a potential for a major new Ni-Cu-PGE sulphide zone at Echo One which is approximately 5 kilometres to the west of Goldbrook's Bravo B4 deposit and 7 kilometres to the east of Goldbrook's Timtu depositThe mineralized zone is exposed at surface and has been intersected beyond 200 metres vertical depth. Supporting field work at Echo One included Crone borehole EM surveys on 22 drillholes, prospecting, structural mapping, a 25-metre spaced ground magnetic survey and a detailed till sampling grid over the basal contact of the Echo One mafic-ultramafic complex.

Ongoing interpretations of the geology, geophysical responses and geochemistry of the Echo One prospect have already indentified critical structural controls on thicker parts of the mineralized zone and have defined preliminary drill targets for a 2011 follow-up program.

Highlights of the Echo One drilling assay results received to date include:

  • ECH10-001, with an inclination of -45 degrees, intersected 20% semi-massive sulphides over 2.71 metres from 55.13 to 57.84 metres downhole, with an average grade of 1.09%Ni, 0.87%Cu and 5.30 g/t PGE+Au . The drillhole ended in peridotite at 306 metres.
  • ECH10-004, with an inclination of -60 degrees, intersected 30% massive and semi-massive sulphides over 6.89 metres from 80.00 to 86.89 metres downhole, with an average grade of 1.41%Ni, 1.03%Cu and 8.33 g/t PGE+Au. The drillhole ended in peridotite at 179 metres.
  • ECH10-006, with an inclination of -65 degrees, intersected semi-massive and vein sulphides over 4.60 metres from 131.40 to 136.00 metres downhole, with an average grade of 0.54%Ni, 0.67 %Cu and 2.42 g/t PGE+Au; and a second intersection from 151 to 152 metres downhole with an average grade of 1.59%Ni, 1.76% Cu and 4.33 g/t PGE+Au. The drillhole ended in peridotite at 250 metres.

Drillcore samples from the 2010 drill program were assayed by ALS Chemex Laboratories in Vancouver, BC [ISO 17025:2005 certified]. Sample preparation was completed at the ALS Sudbury facility. Assay results for nickel, copper and cobalt were determined by 4-acid digestion and ICP-AES finish and report total nickel. Platinum, palladium and gold were determined by fire assay fusion and ICP-AES finish. In addition to the ALS Chemex quality control procedures, Goldbrook inserts Certified Reference Materials, blanks and duplicates into the sample batches for independent quality control.

About Goldbrook

Goldbrook Ventures is engaged in the exploration and development of Nickel-Copper-Platinum Group Element sulphide deposits – a class of mineral deposit that, due to its polymetallic nature, has an advantage of protection against individual metal price cycles and has strong long term supply-demand fundamentals. Goldbrook's quest for discovery is focused in the Raglan District of Northern Quebec, a district that hosts Xstrata's Raglan operations, arguably one of the world's most profitable nickel-copper-PGE mines. Goldbrook is the District's single largest holder of mineral rights, with a 100% interest in 861,000 acres.

Goldbrook's Raglan project is in the third year of an option-joint venture agreement with Jilin Jien Nickel Industry Co., Ltd. ("Jilin Jien") under which they can earn a fifty percent interest in the Goldbrook properties by funding minimum exploration expenditures of $45 million plus reinvestment of Quebec government rebates.

Goldbrook is a shareholder of Jien Canada Mining Ltd. ("Jien Canada") (which successfully acquired Canadian Royalties Inc.), the owner of the nickel-copper-cobalt-platinum-palladium-gold deposits in the Raglan mining district which collectively form the Nunavik Nickel Project. The board of Jien Canada has recently purported to approve an issuance of voting common shares of Jien Canada that would reduce Goldbrook's percentage of voting shares, and consequently Goldbrook's interest in the project, from 25% to 4.21%. Goldbrook has commenced arbitration proceedings against Jilin Jien and others seeking remedies, including declarations that the share issuance violated the terms of the Shareholder Agreement between the parties and that Goldbrook continues to hold 25% of the voting shares of Jien Canada.
