Geoinformatics Announces New Discovery At Its Whistler Project in Alaska

TORONTO, Nov. 4 /CNW/ - Geoinformatics Exploration Inc. (TSX-V: GXL)
("Geoinformatics", "GXL" or the "Company") is pleased to announce that it has
intersected widespread mineralization in the first hole drilled on a regional
prospect called Raintree West, located approximately 1.5 km east of the
Whistler Zone which hosts a NI 43-101 compliant mineral resource estimate.

Highlights

- First hole ever drilled at Raintree West intersected:

- 160 metres grading 0.59 g/t gold, 6.02 g/t silver, 0.10% copper,
0.20% lead, 0.46% zinc (or 1.26 g/t gold equivalent) including:
- 24 metres grading 1.37 g/t gold, 6.32 g/t silver, 0.13% copper,
0.36% lead, 0.80% zinc (or 2.42 g/t gold equivalent).

Raintree West is one of several regional concealed targets drilled by
Geoinformatics during the 2008 summer field season. Assays are pending on
three remaining regional prospects and two holes from the Whistler Zone
itself.
"We are extremely pleased with the discovery of a new mineralized system
on the Whistler Project as it confirms the exploration potential and validates
the Company's innovative exploration techniques," said Mr. Darren Holden,
Chief Operating Officer of Geoinformatics. "We have long suspected that the
mineralization defined at the Whistler Zone is one of many related porphyry
systems on the project. This discovery of widespread porphyry hosted gold
mineralization at Raintree, with comparable grades to those of Whistler's Main
Zone, confirms this theory and bodes well for other similar discoveries to
further enhance the value of the overall Whistler Project."

Raintree West Prospect

The Raintree West prospect lies in a cluster of prospects identified by
the Company using proprietary targeting techniques. Raintree West exhibits a
comparable magnetic signature to that of the Whistler Zone with a coincident
induced polarization (IP) anomaly that extends over 800 metres in length.
Raintree West is a blind target, concealed by a thin veneer (5 metres) of
gravels in relatively flat ground.
Drill hole RN-08-06 was angled west to east and intersected diorite
porphyry rocks immediately below gravel overburden. The first 22 metres of the
diorite porphyry contained low-grade mineralization, below which visible
alteration and veining increased and was accompanied by visible copper, lead
and zinc sulphides over the next 190 metres. The hole remained in diorite
porphyry to the total depth of the hole at 300 metres.

Comment on Metal Ratios and Base Metal Content

Statistical analysis of the assay results shows that the gold in RN-08-06
is directly associated with copper mineralization, as is the case at Whistler.
However, Raintree West's assays exhibit a higher gold to copper ratio of
approximately 5:1 overall. Whistler's Main Zone shows gold to copper ratio of
4:1 compared with 3:1 for the overall Whistler Zone. This, in tandem with the
fact that Raintree West also contains lead and zinc mineralization, suggests
that this intercept may represent the periphery of a gold-copper porphyry
system.

Intercepts calculated using a 0.3 g/t 'gold-equivalent cut-off' on a
minimum 10 metre width and maximum 20 metre internal dilution unless
otherwise noted. Gold-equivalent cut-off is based on the assumptions of
75% recovery of gold and silver and 85% recovery of copper, lead and zinc
and metal prices of US$550 per oz. gold, US$8 per oz. silver, US$1.50 per
lb. copper (as used in the Whistler Resource Estimation and filed on
www.sedar.com) and $0.60 per lb. lead and $0.45 per lb zinc representing
approximately 90% of London Metal Exchange prices on 30th October, 2008.
Gold Equivalent Grade (as opposed to gold-equivalent cut-off) is
presented on the basis of contained metal values assuming the above metal
prices without metallurgical recoveries taken into account and is done in
order to make a direct comparison to the gold value represented in the
gold assay grades.

((*)) Calculated using a 0.7 g/t gold-equivalent cut-off.
((xx)) Calculated using a 1.5 g/t gold equivalent cut-off.

All assays taken on average 2 metre samples of half sawn core and assayed
at Alaska Assay Laboratory located in Fairbanks, Alaska using Fire Assay
for gold and ICP for silver and base-metals. Standards and blanks were
inserted into the sample stream to monitor laboratory performance.

About Whistler Project

The Whistler Project is located approximately 160 km. northwest of
Anchorage, Alaska. Whistler is one of the largest groups of contiguous mineral
claim blocks held by a single company in Alaska, outside of existing mines and
mine development projects.
The Whistler Zone hosts a NI 43-101 compliant Indicated resource of
30 million tonnes grading 0.87 g/t gold, 2.46 g/t silver and 0.24% copper and
an Inferred resource of 134 million tonnes grading 0.64 g/t gold, 2.18 g/t
silver and 0.20% copper. In addition, there is considerable mineralization in
the Whistler Zone that has been identified by drilling and reported in the
43-101 resource technical report filed on SEDAR (www.sedar.com), but has not
yet been categorized as a mineral resource.
The Whistler Zone is just one of a cluster of targets and prospects
within the 440 sq. km. block of 732 State of Alaska mining claims that make up
the Whistler Project. Most of these targets are covered by shallow alluvial
sediments and do not have the significant outcrop of the Whistler Zone, but do
have comparable geophysical, geological and/or geochemical signatures.
