Geoinformatics Announces Significant Gold Mineralization in Drilling and Trenching at its Colorback Project on the Cortez Trend

TORONTO, ONTARIO--(CCNMatthews - Feb. 23, 2007) - Geoinformatics Exploration Inc. (TSX VENTURE:GXL) ("Geoinformatics" or the "Company") is pleased to provide the results of recent drilling and trenching at its 100%-owned Colorback Project located 13 kilometres north of the Cortez/Pipeline gold camp in Nevada.



Highlights

- Drill results include:

- 5.5 metres of 2.98 g/t gold and 5.72 g/t silver including 3.4 metres
of 4.75 g/t gold and 8.08 g/t silver;

- 6.7 metres of 1.89 g/t gold and 2.53 g/t silver; and

- 3.1 metres of 3.66 g/t gold and 23.45 g/t silver including 1.4 metres
of 7.60 g/t gold and 44.30 g/t silver.

- Trenching results include:

- 21.3 metres of 0.47 g/t gold and 2.2 g/t silver; and

- 3.1 metres of 2.48 g/t gold and 2.38 g/t silver.


The Colorback Project is located on the Cortez Trend (also known as the Battle Mountain-Eureka Trend) in northern Nevada (see Figure 1). Geoinformatics originally staked the group of claims comprising its Colorback and Hilltop Projects based on regional modeling and application of the Geoinformatics targeting process, as well as on-ground reconnaissance work. The staking targeted both "upper-plate" rocks which include the Ordovician Valmy Formation and Devonian Slaven Chert Formation, as well as "lower-plate" Devonian carbonate rocks. The interface between "upper-plate" and "lower-plate" rocks is the key structural/stratigraphic feature in northern Nevada that hosts much of the large-scale mineralization in the Cortez and Carlin Trends.

Drilling and Trenching Results

Geoinformatics completed four diamond drill holes totaling 810 metres in two prospect areas known as Discovery and Myers Hill. Trenching was also conducted across the Discovery prospect to map and channel-sample the mineralized fracture zone previously discovered at surface.

The drill holes and trench sampling results show low-grade anomalous gold values throughout the sample areas and define the fracture zone over a width of 150 metres. Individual and higher-grade intercepts are shown in Tables 1 and 2 below. This program is early-stage and the geometry of the mineralized fracture zones is yet to be established. However, the fracture zones are interpreted to be vertical-to-steeply dipping to the SW, and hence intercepts approximate true-width. If the zones are vertical the reported down-hole widths of a 50 degree inclined hole are 1.3 times the horizontal true width.

Mineralization in the drill holes and trench occurs in fracture and breccia zones within upper-plate rocks. The recent drilling confirms that the gold and silver zone encountered in the trench extends to a depth of at least 180 metres. The mineralized fractures and breccia zones are interpreted to be leakage structures that have allowed mineralized fluids to pass from the lower-plate/upper-plate interface to near-surface. The tenor of mineralization in the upper-plate zones is what would be expected from a leakage zone above a Carlin-style mineralized body at depth. The location of the interface is interpreted from a seismic survey to be between 450 and 800 metres from surface at Colorback. Approximately 13 kilometres south of Colorback, the lower-plate/upper-plate interface hosts the giant Pipeline gold mine.

Geoinformatics intends to continue exploration on this project during 2007, which will include further drilling to track the interpreted fracture-leakage zones to the source rocks which, based on regional geology, is expected to be the lower-plate/upper-plate interface, with the target being a Cortez/Pipeline-style deposit at depth.

About Geoinformatics

Geoinformatics is a global exploration company which has developed a unique and innovative approach to mineral exploration. The Company is actively exploring several properties located in British Columbia, the Battle Mountain Trend region of Nevada, and Sinaloa, Mexico. The Company also has an extensive portfolio of other property interests and royalties covering a wide range of minerals in Australia, New Zealand and North America.

The Company has entered into a Master Strategic Alliance Agreement (the "Master Agreement") with Kennecott Exploration Company under which it will use its scientific and technology platform (the "Geoinformatics Process") which integrates data aggregation, data mining and three-dimensional modeling to identify and prioritize 30 or more exploration drill targets over the initial two years of the Master Agreement.

The Geoinformatics Process has been designed to assist in understanding and quantifying risk at a much earlier stage of the exploration cycle than has traditionally been available. The Company's objective is to advance its properties to a stage of commercial development using a faster, less expensive and more reliable analytical methodology to resources exploration.
