Compared to other gold regions around the world, New Zealand is relatively
unexplored with modern exploration techniques. Glass Earth is focussing its
exploration efforts on 4 prospective gold regions in New Zealand: the Hauraki
Region, the Mamaku Region, the Central Volcanic Region and the Otago Region.

NB: In 2009 a forward looking report was produced, rather than in previous years which
reflected the previous 12 months work. This means theres is no '08-'09 document.
HAURAKI GOLD REGION
Glass Earth holds the Waihi West exploration permit
adjacent to the 10 million ounce Martha Gold Mine.
Exploration is being undertaken by Glass Earth’s
Joint Venture partner and Martha mine operator,
Newmont Waihi Gold, in order to determine the strike
extensions of the gold vein systems, which are
interpreted as extending into Glass Earth’s permit.
Glass Earth and Newmont are also advancing
exploration on GEL's prospects in the wider Hauraki the Martha Gold Mine at Waihi
Region, also under JV with Newmont.

MAMAKU GOLD REGION
In 2005 Glass Earth completed 38,000 line kilometres of airborne magnetic and
radiometric surveys over the Mamaku / Central Volcanic Regions, identifying a cluster of
low magnetic zones, coincident with known mineralisation or recorded mineralised
boulders. Glass Earth considers it has identified, through its geophysical surveys, the
extension of the Coromandel Volcanic Arc deep into the Mamaku Region. The Coromandel
Volcanic Arc hosts the Martha mine and Hauraki Goldfield and is considered extremely
prospective. This newly identified extension is on 100% Glass Earth owned permits. Within
the Mamaku Region, Glass Earth has identified 14 new geophysical targets, and is
advancing exploration on its top-ranked prospects, with drilling commenced on the Otawa
/ Muirs / Gibraltar prospect area in August 2008.

CENTRAL VOLCANIC REGION
Epithermal gold mineralisation and active
geothermal systems coexist in this area
situated between Rotorua and Taupo. The
Waiotapu geothermal pools (south of Rotorua)
are actively depositing gold at ore grade
(16g/t Au) as gold arsenic and antimony
compounds in silica. This area’s characteristics
highlight the gold potential of the region.
Glass Earth has used a combination of legacy
data and high definition airborne geophysics to The champagne pool at Waiotapu
identify its targets, and is following these up
with intensive on-ground exploration: resistivity surveying, soil sampling and geochemical
testing, geological mapping and drilling. Glass Earth’s first drill hole at Tahunaatara
intersected a new large epithermal gold system.

OTAGO GOLD REGION
The Macraes gold mine, as well as the 8 million ounces of alluvial gold recovered, attest to
the capacity of the Otago region to host significant gold mineralisation.
Currently, there is no well understood generic mineralisation model for the Otago style
gold mineralisation, and even less understanding of the geophysical signatures associated
with mesothermal gold deposits in the Otago region.
Glass Earth, by reprocessing and interpreting legacy data, has defined the Macraes mine's
geophysical signature, therefore opening up the region for exploration of “covered” gold
mineralisation. Glass Earth was granted the largest gold prospecting permit in NZ (PP 39
322) in December 2006, over 17,980km2 of the Otago region – this was the trigger for
Glass Earth’s second Airborne Geophysics Campaign and Data Intervention over 13,000
km2 of mesothermal terrane, which was completed in August 2007.
