DDH ECH10-021 Intersects 7 m of 1.14% Ni, 1.77% Cu, 0.07% Co and 8.98 g/t PGE+Au

VANCOUVER, BRITISH COLUMBIA -- (Marketwire - Dec. 21, 2010) - Goldbrook Ventures Inc. ("Goldbrook" or the "Company") (TSX VENTURE: GBK) is pleased to announce 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 an expansion along strike of the recently reported discovery (October 22, 2010 news release) of a significant and apparently extensive high grade palladium-platinum-nickel-copper sulphide system at the Echo One prospect located between Goldbrook's Timtu and Bravo deposits (NI43-101 compliant resources described in November 5, 2010 news release). The results expand the Echo One zone strike length to about 700 m and the zone appears to increase in grade and thickness particularly in the vicinity of drillholes ECH10-21 and ECH10-25 with 21 m and 58.9 m intersections respectively.

The Echo Ultramafic Complex was identified as an under-explored and high priority target during 2010 pre-season targeting led by a team from Revelation Geoscience Ltd. Historical exploration identified narrow intervals of high grade Ni-Cu-Pd sulphides associated with a strike-extensive gossan at Echo One. (see detail at http://www.goldbrookventures.com/EN/echo_one/)

During the 2010 drilling campaign, 32 diamond drill holes totalling 6193 metres were completed within the Echo One prospect. These holes were drilled along the southern contact of the Echo One complex over a strike length of 1600 metres. Twenty-eight of these drillholes intersected nickel-copper-palladium sulphide mineralization located both within, and at the contact of, the large composite ultramafic complex.

The Echo One mineralized zone is exposed at surface and has been intersected beyond 225 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 interpretation of the geology, geophysical responses and geochemistry of Echo One 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 reported below include:

- ECH10-021, with an inclination of -55 degrees, intersected sulphides over 21.00 metres from 217.00 to 238.00 metres downhole, with an average grade of 0.46% Ni, 0.93% Cu, 0.03% Co, 3.93 g/t PGE+Au, which calculates to 1.77% Ni Equivalent, including 7.00 metres from 223.57 to 230.57 metres downhole, with an average grade of 1.14% Ni, 1.77% Cu, 0.07% Co and 8.98 g/t PGE+Au, which calculates to 4.00% Ni Equivalent. The drillhole ended in graphitic argillite at 290 metres.

- ECH10-025, with an inclination of -65 degrees, intersected sulphides over 58.90 metres from 121.10 to 180.00 metres downhole, with an average grade of 0.53% Ni, 0.50% Cu, 0.03% Co and 2.05 g/t PGE+Au, which calculates to 1.24% Ni Equivalent. The drillhole ended in peridotite at 271 metres.

Echo One is considered to be a new style of mineralization in the Raglan District with a significant value contribution from higher grade Palladium. These new intercepts are also being reported in nickel equivalent values in order to reflect the polymetallic nature of the mineralization.

NOTE 1: Intersections are reported as actual core lengths, true widths may be less than core widths depending on the angle of the hole and orientation of the intersection

NOTE 2: Ni equivalent calculations use metal prices from the November 2010 NI43-101 P&E Mining resource estimates for Goldbrook's Belanger-Delta Trend deposits. These prices, being US$8.92/lb for nickel, US$2.93/lb for copper, US$$20/lb for cobalt, US$1143/oz for platinum, US$354/oz for palladium, and US$975/oz for gold. As no metallurgical studies have been completed to date, metallurgical recoveries and net smelter returns are assumed to be 100%.

Analyses

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.
