Geoinformatics Identifies a New Copper-Rich Zone at its Whistler Project in Initial 2007 Assay Results

TORONTO, ONTARIO--(Marketwire - Oct. 1, 2007) - Geoinformatics Exploration Inc. (TSX VENTURE:GXL) ("Geoinformatics" or the "Company") is pleased to announce the assay results for the first two drill holes from the 2007 exploration program on its Whistler Project in Alaska. The drilling is the first completed by Geoinformatics following acquisition of the project from Kennecott Exploration Company ("Kennecott") in June 2007. The first drill hole (WH-07-01) primarily evaluated an untested section of the high-grade core (the "Main Zone"), which is located within the broader "Whistler Zone" porphyry system. The second hole (WH-07-02) successfully tested both a possible western extension of the Whistler Zone as well as a deeper extension of the Main Zone (see "The Whistler Project") below.


- Assay results confirmed wide intercepts of gold and copper-rich
mineralization in both target zones within the Whistler Zone porphyry.

- WH-07-01 intersected approximately 50 metres of mineralization in the
Whistler Zone before intersecting the following higher-grade intervals
within the Main Zone (see Table 1):

- 47.0 metres grading 1.11 g/t gold, 0.40% copper, 3.13 g/t silver, and

- 49.2 metres grading 1.06 g/t gold, 0.23% copper and 3.37 g/t silver.

The drill hole ended in mineralization in a 19-metre section of 1.91 g/t
gold, 0.39% copper and 3.05 g/t silver well before the target depth due to
a casing failure.

- WH-07-02 successfully established a western extension to the Whistler
Zone and intersected a new high-grade adjunct to the Main Zone, recording
some of the highest grades seen to-date at Whistler including
(see Table 2):

- 132.0 metres grading 0.56 g/t gold, 0.16% copper, 0.71g/t silver, and

- 47.0 metres grading 1.60 g/t gold, 0.40% copper, 2.06 g/t silver,
which included a high-grade copper zone of 8.0 metres of 1.20% copper
and 4.10 g/t gold.

- SRK Consulting Canada Inc. ("SRK") has been engaged to complete a
National Instrument 43-101 ("NI 43-101") technical report on the Whistler
Project, which is expected by the end of October, 2007.

The Whistler Project

The Whistler Project was acquired as a target-of-merit from Kennecott in June 2007 (see "Kennecott - Geoinformatics Alliance Agreement" below), and encompasses approximately 440 sq. km. in the northeastern corridor of the prospective Southern Alaskan Range which hosts the giant Pebble copper-gold-molybdenum-silver deposit further to the southwest. The project is located 160 km. northwest of Anchorage, Alaska (See Figure 1) and consists of 732 mining claims on state land designated for mineral exploration and development.

The initial discovery on the Whistler land package was a broad, partially-defined gold-copper system now known as the Whistler Zone which comes to surface and has a mineralized envelope confirmed over an area of 760 metres by 460 metres to a depth of at least 570 metres.

To view Figure 1 Whistler Project Location, please visit the following link:

The Whistler Zone was originally identified in the 1980s in shallow drilling by Teck Cominco Limited, which was followed by 15 Kennecott drill holes (7,950 metres) from 2004 to 2006 to depths of 580 metres (vertical) below surface. Within this broadly mineralized envelope, the higher-grade Main Zone extends for 350 metres along strike averaging over 100 metres in width with mineralization confirmed from surface to depths of between 200 and 570 metres. Overall, the Main Zone and the Whistler Zone are still open in several directions and at depth.

Another 15 promising targets/prospects have been identified in the Whistler Project region through field reconnaissance and computer-based targeting methods completed by Geoinformatics and Kennecott, which include an airborne magnetic survey, surface geochemistry and induced polarization ("IP") geophysical surveys.

Geoinformatics expects the full assay results from the 2007 field season to be available by late October to early November, 2007. SRK has completed an initial review and field visit to the Whistler Project and an NI 43-101 summary report is expected to be released in October 2007.

Initial Whistler 2007 Drill Program Results

"Geoinformatics is extremely pleased with the results of its first two drill holes on Whistler" stated Darren Holden, Executive Vice President, Exploration. "The higher-grade Main Zone has been proven to have good continuity of grade and width with over 96 metres of higher-grade mineralization intersected in the first hole before the hole was abandoned while in mineralization".

The second drill hole indicates the widespread presence of lower grade mineralization on the western side of the Whistler Zone from a 132-metre intercept grading 0.56 g/t gold and 0.16% copper. This drill hole also intersected a higher-grade zone of 47 metres of 1.6 g/t gold and 0.4% copper, which is either a new high-grade zone or a western extension of the Main Zone. Within this interval, a high-grade copper zone was intersected grading 8.0 metres of 1.20% copper and 4.10 g/t gold. Encouragingly, the style of mineralization in the high-grade copper zone, consisting of brecciated porphyry within a sulphide matrix, is different to the vein-hosted mineralization in the Main Zone.

The Whistler 2007 exploration program is now expected to consist of seven drill holes totaling 3,200 metres. The first two drill holes are the subject of this press release, four holes are pending assay results and one hole is currently being completed. In addition, Geoinformatics is conducting regional reconnaissance of several other targets in the Whistler area through computer-based targeting techniques, field mapping and sampling, and IP surveys.

2007 Drill Hole 1 - WH-07-01

WH-07-01 was drilled primarily to infill a section of the Main Zone, which was identified in previous Kennecott drilling. Gold mineralization greater than 0.3 g/t was intercepted in several long intersections from 61 metres to the end of the hole at 308 metres. The last 19.2 metres contained the highest-grade mineralization in this drill hole grading 1.91 g/t gold, 0.39% copper and 3.05 g/t silver. The hole ended well before the target depth due to a slip in the drill hole casing.

The Main Zone is interpreted to be dipping between vertical to 85
degrees to the west. In a 55 degree inclined hole drilled on azimuth
090, the true width is approximately 0.6 to 0.7 of the width of the

2007 Drill Hole 2 - WH-07-02

WH-07-02 was designed to evaluate an untested portion of the Whistler Zone porphyry located west of the Main Zone as well as a possible extension of the Main Zone at depth.

The orientation of the mineralization is unknown, and, hence, the
true width cannot be estimated.

The drill hole included a high-grade copper zone of 8.0 metres grading 1.20% copper and 4.10 g/t gold based on a 0.50% copper cut-off. The same section of the hole measured 14.0 metres grading 2.60 g/t gold, 0.71% copper using a 1.0 g/t gold cut-off, and is one of the best copper-gold grade intercepts seen to-date at Whistler.
