Petro Horizon Initiates a 43-101 Report on its Lithium, Rare Metals Project

VANCOUVER, Canada, March 18, 2010 - The Company is pleased to announce that it has retained Mercator
Geological Services Limited to expedite the completion of a 43-101 report on
the Brazil Lake Lithium and Rare Metals Property. Upon receipt of the
43-101 report expected within the next 45 days, the company will announce
its 2010 work program immediately thereafter.

Mercator Geological Services Limited is based in Dartmouth, Nova Scotia
and has extensive experience with local Nova Scotia geology including the
granitic intrusions similar in age to those that are thought to be associated
with Brazil Lake Lithium Rare Metals Property.

An initial site visit was recently conducted in early March attended by
Mercator geologist, Mike Cullen and Petro Horizon's president, Ron Bourgeois.
The trip also included several meetings with community and business leaders
and well as meetings with the Nova Scotia Department of Natural Resources.

Petro Horizon president, Ron Bourgeois stated, "My initial impression is
there is significant support from both the provincial government and the
local mining industry in our proposed endeavour at Brazil Lake."

About Brazil Lake Lithium Rare Metals Project

The 3,160 acre property that is yet to be diligently explored by the
company, is located approximately 30 Kilometers north of Yarmouth, Nova
Scotia and 12 kilometers west of the Avalon Rare Metals (AVL) East
Kemptville Project. Drilling to date on the Property has successfully
revealed two Lithium bearing pegmatite dikes in addition to a host of other
rare metals such as tantalum, niobium, beryllium, tungsten tin and rubidium.
Metallurgical bench testing to date has also revealed other potential
economic targets include cosmetic grade mica, silica chloride, aluminum
chloride and rubidium enriched potassium feldspar.

The two identified lithium and rare metal bearing pegmatite dikes that
appear at surface have been defined by drilling to be up to 20 meters wide
and having exposed lengths up to 300 meters long. The deepest drill hole
intersected the dikes at 50 meters depth. Both pegmatites remain open at
depth and future drilling in the upcoming work program will attempt to
extend the depth of the dikes to a minimum of 100 meters.

The signature dispersal train of pegmatite boulders identifying the
currently drilled pegmatites will assist in identifying three other boulders
fields indicating potential pegmatite targets. Geochemical surveys have also
assisted in the identification of these additional targets. It is well known
that pegmatites occur in swarms and therefore, the company, in addition to
the drilling program on the currently established two dikes, plans to carry
out a detailed prospecting program to source other potential targets.

Lithium on the property is hosted by the mineral spodumene which makes
up approximately 14 to 20% of the pegmatites. The lithium oxide (Li(2)O)
content in the spodumene is approximately 7.4% to 7.7%.

The Contained Rare Metals

On March 2nd, the Company announced assay results from the drill holes
that addressed the rare metals contained within the pegmatites. These
included rubidium ("Rb"), beryllium ("Be") and tantalum ("Ta"). Examples of
the grades included Hole No. 02-15 in the lithium pegmatites which returned
values up to 1398 parts per million ("ppm") Rb over 15.3 meters including
2625 ppm Rb over 4.2 meters. Hole No. 02-24 in the lithium pegmatites
returned values up to 200 ppm Be over 35.8 meters including 304 ppm Be over
14.9 meters. Hole No. 93-2 in the lithium pegmatites returned values up to
102 ppm Ta over 24 meters including 541 ppm Ta over 1.0 meter. Metallurgy
regarding the rare metals was addressed in previous metallurgy work that was
confirmed at Dalhousie University. The results were positive and encouraging
and it is the company's intention to release news on these results shortly.
