Goldbrook Announces Mine and Infrastructure Construction Underway for the Nunavik Nickel Project, Ungava

NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE
UNITED STATES


Goldbrook Ventures Inc. ("Goldbrook") (TSX VENTURE:GBK) announces that the
Directors of Jien Canada Mining Ltd. ("Jien Canada") have approved a project
development budget of $122,400,000 for 2010, and have additionally approved a
construction program which targets Q1 of 2012 for the commissioning and start-up
of a mill and the necessary infrastructure to exploit the known resources of the
Nunavik Nickel Project, located in Ungava, Northern Quebec. Goldbrook owns 25%
and Jilin Jien Nickel Industry Co., Ltd. owns 75% of the voting shares of Jien
Canada. Jilin Jien is responsible for providing 100% of the funding to bring the
Nunavik Nickel Project into production and will be repaid for its contribution
out of cash flow from production on the property if commercial production
occurs. 


Ongoing work on site includes the preparation during this construction season of
fuel storage, personnel accommodations, roadwork, pre-stripping of the Expo and
Mesamax deposits to generate construction material, Bombardier Dam site,
concrete foundations for the mill site, structural steel erection and
engineering studies in preparation for subsequent work. See photos at:

Lavalin were selected as the engineering, procurement and construction
management services (EPCM services) contractor and they began work in early June
based on a letter-of-intent. In connection with the construction activities,
application has been made to regulatory authorities in Quebec for a permit to
operate a 4,500 tpd mill at the site of the Nunavik Nickel Project (an upgrade
from the 3,500 tpd mill currently permitted). Additionally, roadwork and
earthworks are being executed by Kiewit-Nuvumiut based on a letter-of-intent.
Current plans anticipate various infrastructure components to be advanced
sufficiently to allow construction to continue through the winter months into
2011 leading to an anticipated start-up in the Q1 of 2012. An updated
feasibility study on the Nunavik Nickel Project is expected to be delivered in
the fourth quarter of 2010.


Goldbrook Ventures Inc. previously commissioned P&E Mining Consultants Inc. to
carry out an independent, compilation of previously released (Goldbrook PR April
10, 2010), NI 43-101 compliant resource estimates for the Allammaq, Expo,
Ivakkak, Mequillon, Mesamax and Puimajuq Deposits which are the foundation of
the Nunavik Nickel Project. The work included a review of the geology,
exploration history, historical resource estimates, a description of the deposit
types and other information relevant to understanding the geology and
exploration programs carried out on the Property. A copy of this report entitled
"Technical Report on the Allammaq, Expo, Ivakkak, Mequillon, Mesamax and
Puimajuq Ni-Cu-PGE Deposits of the Nunavik Nickel Project, Nunavik, Quebec", and
dated April 14, 2010 is filed on SEDAR at www.sedar.com, and on the Goldbrook
website: www.goldbrookventures.com under Nunavik Nickel Project.

(1) Mineral resources which are not mineral reserves do not have            
    demonstrated economic viability. The estimate of mineral resources may  
    be materially affected by environmental, permitting, legal, title,      
    taxation, socio-political, marketing, or other relevant issues.         
(2) The quantity and grade reported in this inferred resource estimation are
    conceptual in nature and there has been insufficient exploration to     
    define an indicated mineral resource on the property and it is uncertain
    if further exploration will result in discovery of an indicated or      
    measured mineral resource on the property.                              



The mineral resources in these estimates were calculated using the Canadian
Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral
Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing
Committee on Reserve Definitions and adopted by CIM Council December 11, 2005.


Jien Canada, and its team of senior management, professional employees, skilled
trades people and contractors will be in charge of bringing the Nunavik Nickel
Project into production on a timely and environmentally friendly basis. 


In addition to the Nunavik Nickel Project mine construction, under the Option
Joint Venture Agreement between Goldbrook and Jilin Jien on Goldbrook's Raglan
property, Goldbrook is currently executing an extensive exploration program with
a budget of $17,500,000. The exploration program is being operated out of two
camps, with 5 drills and with a target of up to 25,000 metres of drilling. The
goals for the 2010 program will be to further delineate previously identified
mineralized zones and conduct an extensive reconnaissance program to better
understand the mineral potential across the extensive land holdings, comprising
some 863,000 acres.


Additionally, Goldbrook has learned that Canadian Royalties and its former
directors, and certain of its current and former officers have been named as
defendants in a purported securities class action lawsuit filed in the Ontario
Superior Court of Justice. The complaint alleges, among other things, that the
defendants made material misrepresentations about Canadian Royalties' operations
and prospects in various public statements and filings from June 21, 2007
through August 5, 2008. The lawsuit also names Jien Canada as a defendant and
seeks a declaration that it be bound by the court's findings with respect to the
liability of Canadian Royalties and its former directors, and certain of its
current and former officers. The time period that the alleged misrepresentations
relate to is prior to the acquisition of Canadian Royalties by Jien Canada.
Neither Goldbrook nor any of its directors or officers are named as defendants
in the lawsuit. Jilin Jien is responsible for funding 100% of the costs of any
lawsuits against Jien Canada.


Mr. Antoine Yassa, P.Geo., Mr. Eugene Puritch, P.Eng., and Ms. Tracy Armstrong,
P.Geo., all independent Qualified Persons as defined in NI 43-101, have reviewed
and approved the scientific or technical information in this press release.


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
863,000 acres.


Goldbrook also owns 25% of the voting shares of Jien Canada Mining Ltd. (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.
