Petrostar Petroleum Reaches Commercial Milestone With DHT Technology Sale

VANCOUVER, BRITISH-COLUMBIA, Mar 24 (MARKET WIRE) --
Petrostar Petroleum Corporation (TSX VENTURE: PEP)(Frankfurt:
LMQ)("Petrostar") is pleased to announce that Oilsands Quest Inc. of
Calgary, AB, has purchased a DHT2C unit for their Axe Lake, SK doubling
the number of units at their facility. The DHT technology is assisting
Oilsands Quest in its development of the Province of Saskatchewan's
emerging oil sands industry. Oilsands is a leader in the establishment of
the Province of Saskatchewan's emerging oil sands industry, with major
acreage permits and licenses in both Saskatchewan and Alberta. Their new
DHT configuration (DHT2C) will address the specific needs required by
Oilsands Quest, in particular their facility requires a DHT operating at
200-250 meters and with greater length heating rods and housing. In
addition, the new unit will be a lighter skid mounted with telescoping
mast and hydraulic controls making it a compact unit. This will enable
the unit to be air lifted via helicopter providing access to additional
locations over the large acreage of the project.

As previously announced in September 2008 the Company entered into a
rental agreement with Oilsands Quest whereby Oilsands would test
Petrostar's DHT (Down Hole Tool-DHT2) at their Northern Axe Lake, SK
facility. The agreement has been extended an additional 3 months to May
2009 from the original September agreement

DHT & ETH Technology Review

The Down Hole Tool (DHT) is a system and method for generating controlled
underground heat/steam and pressure. Specifically, the present invention
relates to an electrical steam/heat generation system that enables
efficient production of down-hole heating and steam production without
the typical heat and pressure loss of traditional surface steam
generation equipment. In addition to the DHT model for enhanced
production deployment the Company will proceed with an additional model
to address the waxing problem experienced in light oil production. A
prototype is expected to be available for fieldtesting within the next 30
days.

The Electric Tank Heater (ETH) unit is capable of replacing current
burner tube tank heating devices and has a zero CO2 emission signature,
as well as being capable of reducing operating costs by using power
generated from top drive motors and eliminating the fuel requirements of
the burner units. Full CSA mass approvals are anticipated in April 2009,
which will make the units available for installation at the manufacturing
level as the alternative to current burner tube installations. More
information on the DHT and its storage tank ETH is available on the
Company website at www.petrostarpetroleum.ca.

completion of production operations; risks with respect to oil prices, a
material decline in which could cause the Company to delay or suspend
planned drilling operations or reduce production levels; and risks
relating to the availability of capital to fund drilling operations that
can be adversely affected by adverse drilling results, production
declines and declines in oil prices and other risk factors.
