PETROSTAR PETROLEUM REPORTS 600% PRODUCTION
INCREASE USING PROPRIETARY OIL RECOVERY TECHNOLOGY.

Petrostar Petroleum Corp. has successfully completed initial field testing of its enhanced oil
recovery technology, or as it is currently described, downhole heating device (DHT). The test
commenced May 2, 2007, and concluded May 25, 2007. The initial test well A9/16 was tested
for approximately 10 to 14 days at which time the tool test data were reviewed and evaluated.
The testing has produced a significant 600-per-cent increase in production from the original
well production. Historical fluid production on test well 9/16 increased from 2.1 cubic metres
(13.21 barrels per day) to nine to 12 cubic metres (56.6 to 75.5 bpd). The company has
decided that given the initial successful testing on well A9/6 that it will also test well 15/6 where
it is expected that there will also be a significant increase in its daily production.

During initial testing, the DHT was tested under several different configurations and well bore
depth settings to determine the optimum placement in conjunction with well perforations,
production zones, well fluid levels and wellhead pressure as well as testing the fail-safe safety
shutdown in case of electrical malfunctions. The fail-safe tests passed with 100-per-cent
efficiency. The testing has provided the company with information that will lead to modifications
on its beta design that will increase downhole temperatures to approximately 225 to 248 C
while allowing it to achieve and maintain that temperature in shorter time frames.

With these promising results, the company is immediately proceeding with the manufacture of
six of the new configuration DHT units, to be manufactured by Valex Industries of Richmond,
B.C. The units will be used for additional tests to be conducted on both heavy and light oil
formations. The tests will be supervised by B. Cabot, president of Western Petroleum
Management of Calgary, Alta., Canada.

The success of the downhole heating device test is viewed as a significant milestone achieved
by Petrostar and it brings the company one step closer to ultimately commercializing this
revolutionary enhanced oil recovery technology. The company believes it can deliver the DHT
at a cost that can effectively and economically revitalize tens of thousands of proven North
American medium and heavy oil wells. Needless to say, the opportunity of penetrating this
market is substantial.

We seek Safe Harbor.
