Drill Results Confirm Second Mineralized Porphyry at the Whistler Project


    TORONTO, July 11 /CNW/ - Geoinformatics Exploration Inc. (TSX-V: GXL)
("Geoinformatics" or the "Company") is pleased to announce that the first
drill hole in its 2008 southern Alaskan regional exploration program has
confirmed the discovery of a second mineralized porphyry system ("Rainmaker")
at the Whistler Project.
    Rainmaker is located approximately 2 km. east-southeast of the Whistler
Zone which hosts a National Instrument 43-101 ("NI 43-101") compliant gold
resource of 840,000 ounces in the Indicated category and 2.7 million ounces in
the Inferred category, plus additional copper and silver credits.

    Assays from the drill hole at Rainmaker (RM-08-01) returned 151.6 metres
grading 0.37 g/t gold, 0.18% copper, 0.74 g/t silver (0.72 g/t
gold-equivalent) and included higher-grade intercepts of:

    -  83.0 metres grading 0.47 g/t gold, 0.21% copper, (0.86 g/t
       gold-equivalent); and

    -  11.8 metres grading 0.17 g/t gold, 0.32% copper, 8.96 g/t silver
       (0.90 g/t gold-equivalent).

    Mr. Darren Holden, Executive Vice President, Operations of
Geoinformatics, commented, "These excellent drill results, combined with the
prior (2005) drill hole, indicate that Rainmaker hosts a mineralized system
with wide intercepts and has the potential to become a second resource to
complement the Whistler Zone. The intersection of highly altered porphyry
throughout this drill hole indicates that the Rainmaker system may have a size
comparable to the Whistler Zone porphyry. In addition, the occurrence of a
pyrite sulphide zone with low-grade zinc anomalism in the lower portion of the
hole is significant as this is typical of zones on the periphery of a major
copper-gold porphyry system."

    Rainmaker Drill Results

    The inclined (55 degrees) hole was drilled from northeast to southwest
and was designed to test the extent of mineralization adjacent to a prior
vertical hole drilled by Kennecott Exploration Company ("Kennecott") in 2005,
which recorded 168.5 metres grading 0.47 g/t gold and 0.17% copper (0.82 g/t
gold-equivalent). The rock-type and mineralization at Rainmaker is comparable
to the mineralized diorite porphyry at the Whistler Zone. Copper (and
associated gold) mineralization is hosted in chalcopyrite (CuFeS2) and occurs
as disseminated grains and within veins and fractures in an altered diorite

    Intercepts are calculated using a 0.3 g/t gold-equivalent cut-off unless
    otherwise noted. Gold-equivalent cut-offs are determined based on the
    assumption of 75% recovery of gold and silver and 85% recovery of copper,
    with metal prices of US$550 per oz. gold, US$8 per oz. silver, US$1.50
    per lb. copper. Gold-equivalent cut-offs and grades are reported
    consistent with the methodology of the Whistler NI 43-101 resource
    estimation produced by SRK Consulting (Canada) Ltd as filed on SEDAR

    (*) indicates higher-grade intercepts calculated using a 0.7 g/t

    All intercepts calculated on a minimum 10 metre width and maximum 20
    metre internal dilution.

    1.  Gold-equivalent grades (not gold-equivalent cut-offs) are reported on
        the basis of contained metal values and the metal prices set out
        above without consideration of metallurgical recoveries.

    2.  Assay results for 05-DD-WH-REC-08 have been revised from those
        previously reported based on the use of standardized cut-off grades
        from the NI 43-101 resource estimate on the Whistler Zone. The
        results were previously reported as 184 metres grading 0.44 g/t gold
        and 0.16% copper.

    BD = Below Detection.

    Assayed samples consisted of half-core with average 2-metre intervals.
    All samples were prepared and assayed at the Alaska Assays Laboratory in
    Fairbanks, Alaska using Au Fire Assay (FA30) for gold and multi-element
    analysis (ICP-4A). Field standards and blanks were inserted in the sample
    stream to monitor laboratory performance. Refer to Figure 1 below for a
    discussion of "true-width".

    The Whistler Project

    Rainmaker lies within the Whistler Project, a 440 sq. km. project located
160 km. northwest of Anchorage, Alaska. The Whistler Project 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 an 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 Project hosts a cluster of targets and prospects, most of
which are covered by shallow alluvial sediments and do not have the
significant outcrop of the Whistler Zone, but do have comparable geophysical,
geological or geochemical signatures. Geoinformatics is applying proprietary
data modeling to analyze and prioritize other targets for drilling.

    Kennecott - Geoinformatics Alliance Agreement

    The Whistler Project was conditionally conveyed to Geoinformatics under
the target-of-merit provisions of the Kennecott-Geoinformatics Master
Strategic Alliance Agreement (the "Alliance Agreement") in June 2007, and all
Whistler targets and prospects mentioned in this press release fall under it.
Please refer to Geoinformatics' press release dated June 7, 2007. The Company
entered into the Alliance Agreement effective March 2006, under which it has
been using its proprietary geo-science and technology platform (the
"Geoinformatics Process") to identify, prioritize and drill more than 30
exploration drill targets over the initial two years of the Agreement.
Kennecott retains a back-in right to acquire either a 51% or 60% interest or a
2% NSR in the Whistler Project and all other projects subject to the Alliance
Agreement, which is exercisable under certain circumstances. Please refer to
Geoinformatics' press-release dated August 14, 2006, for further information.
