Great Panther Discovers New Silver-Gold Zones At Guanajuato
======================================================================

GREAT PANTHER RESOURCES LIMITED (TSX: GPR) is pleased to announce that
surface diamond drilling has intersected four new silver-gold zones and
provided further definition on the three previously known zones of
silver-gold mineralization in the Promontorio area of the Company's
wholly-owned Guanajuato Mine in Guanajuato, Mexico. All zones are
sub-parallel and occur within 70 metres of the main Veta Madre. Having
several zones within close proximity like this will significantly lower
their development costs and plans are already in preparation for the
exploitation of this area. The new mineralization lies between 70 and
150 metres below surface and is accessible by ramp.

This portion of the 2007 drill program comprised 2,135.8 metres in
eleven holes (SG07-035 to SG07-045) and was focused on defining
mineralization in the Promontorio / Garrapata area - the southern most
area of exploitation in the Guanajuato Mine Complex. Previous results
from this part of the mine were announced on Dec. 12, 2006.
Mineralization in this area is now known to comprise at least seven
parallel zones: the main Veta Madre, a hangingwall zone ('HW' -- above
the Veta Madre) and five footwall zones ('FW' -- below the Veta Madre).
The Veta Madre quartz breccia occurs at the fault contact between
hangingwall conglomerates and a footwall mix of metasediments,
metavolcanics, and intrusions. The hangingwall zones occur as quartz
stockworks in the conglomerates. The footwall zones have been divided
into the FW #1a, #1b, #1c, #2, and #3 zones and are associated with
quartz stockworks and breccias. The FW #1 and #2 zones are hosted
within diorite and quartz-feldspar porphyry intrusions, while the #3
zone occurs at the lower contact between the intrusions and footwall
metasediments.

The HW zone was cut by drill holes SG07-035 to 037, and 040 to 045 and
displays a higher gold:silver ratio than other zones. Examples of this
include 21.2g/t gold and 52g/t silver over 0.88 metres in SG07-035;
11.1g/t gold and 13g/t silver over 1.15 metres in SG07-036; 9.95g/t
gold and 477g/t silver over 1.05 metres in SG07-037; and 23.45g/t gold
and 45g/t silver over 2.45 metres in SG07-043. The HW zone has been
traced for more than 150 metres along strike and up to 100 metres down
dip.

The Veta Madre itself was intersected in all holes except SG07-041,
which was lost in an old stope. Signs of former mining along the Veta
Madre were noted in seven of the eleven holes in this program, however
no signs of previous mining were observed in the FW zones. Parts of
the Veta Madre have been left in place as evidenced by several
mineralized intersections, including 1.98g/t gold and 77g/t silver over
2.59 metres in SG07-038 and 2.39g/t gold and 202g/t silver over 3.55
metres in SG07-043. As such, an in situ and well mineralized portion of
the the Veta Madre zone has been traced for more than 150 metres along
strike and up to 150 metres down dip.

The FW #1a zone was described in the last Promontorio news release (Dec
12, 2006) as the footwall #1 zone in drill holes SG06-033 and 034. The
2007 drilling has added to this with intersections in holes SG07-036
through 040, 042, 044, and 045. FW #1a is located 5-10 metres below
the Veta Madre. Noteable intersections include 18.28g/t gold and
104g/t silver over 2.16 metres in SG07-036; 4.58g/t gold and 312g/t
silver over 3.09 metres in SG07-037; and 2.02g/t gold and 265g/t silver
over 3.60 metres in SG07-040. The FW #1a zone has been traced for more
than 100 metres along strike and up to 100 metre down dip.

The FW #1b zone is located only 5 metres below the FW #1a zone, and was
intersected in holes SG07-035, 036, 039, 040, and 042 to 045.
Highlights from this zone include 0.93g/t gold and 181g/t silver over
2.47 metres in SG07-039 and 2.35g/t gold and 430g/t silver over 2.42
metres in SG07-040. To date, the FW #1b zone has been traced for more
than 50 metres along strike and up to 75 metres down dip.

The FW #1c zone is located 5-10 metres below the FW #1b zone, and was
intersected in SG07-036, 039, 040, and 045. Noteable intersections
include 0.78g/t gold and 266g/t silver over 5.61 metres in SG07-036 and
1.26g/t gold and 292g/t silver over 3.10 metres in SG07-040. This zone
has been traced for 50 metres along strike and up to 75 metres down
dip.

A new footwall zone (designated FW zone #2) has been discovered
approximately 50 metres below the Veta Madre and was intersected in
holes SG07-035, 038, 039, 040, 042, and 045. This zone appears to be
significantly thicker than some of the others with intercepts such as
6.15 metres of 1.20g/t gold and 206g/t silver in hole SG07-042 and 5.60
metres of 0.71g/t gold and 115g/t silver in SG07-045. The FW zone #2
has been outlined for more than 50 metres along strike and up to 50
metres down dip.

A second new discovery (designated FW zone #3) lies approximately 70
metres below the Veta Madre and was intersected by holes SG07-042 and
043a, approximately 25 metres apart. These holes returned 2.97g/t gold
and 175g/t silver over 1.10 metres and 1.55g/t gold and 194g/t silver
over 2.31 metres, respectively. Longitudinal sections showing all of
the Promontorio drilling can be found in the Guanajuato Mine section of
the Great Panther website at www.greatpanther.com.

There is no indication from drilling or a review of underground survey
maps that the footwall zones have been previously mined. Drill hole
spacing in this program was approximately 30 metres on average. At
this spacing, the mineralized zones are observed to vary in thickness,
and grades are also quite variable. Detailed drilling to further
delineate and extend the zones will be required and will be carried out
from existing underground workings that are now being re-habilitated.

To date 6,385 metres of surface drilling have been completed in 2007 at
Guanajuato and the program is still underway, detailing and expanding
the various zones associated with the prolific Veta Madre structure.
This includes the aforementioned holes SG07-035 to 045 at Promontorio,
holes SG07-046 to 052 at Tepeyac shaft (south of Valenciana Mine
shaft), SG07-053 to 058 at Remedios shaft (north of Cata Mine shaft),
and SG07-059 to SG07-065 at two other Promontorio area drill sites.
Results from all areas will be released as they become available.

The discovery of these new zones at Promontorio is significant, not
only because of the near term potential for development but also
because they imply that much of the footwall and hangingwall to the
Veta Madre has been largely unexplored and, therefore, undeveloped.
With more than 4 kilometres of strike length existing on the mine
property, the potential for additional zones to be found is excellent.
