GREAT PANTHER RESOURCES LIMITED (TSX: GPR) (the "Company") is
pleased to provide an update on the successful mine development of
three areas hosting high grade silver-gold-lead-zinc mineralization
at the Topia Mine. The three development areas are along the San
Gregorio, Rosario and Don Benito veins. As part of the mine
expansion plans (GPR news release September 16, 2009), these and
other veins at the Topia mine will contribute substantially to
future success. Plan maps and sections can be viewed at
http://www.greatpanther.com/s/TopiaMine.asp.
At the San Gregorio vein, development since the last update (GPR
news release January 26, 2009) includes further advance west on the
vein which includes a portion measuring 100 metres along strike
averaging 1,949g/t silver, 0.28g/t gold, 10.36% lead, and 17.68%
zinc over an average 0.54 metre width. In addition, sub-level
development and stoping has commenced further west from the
aforementioned vein portion and averages 1,809g/t silver, 0.41g/t
gold, 5.84% lead, and 14.76% zinc along a 70 metre strike length,
with an average 0.34 metre width. Further development of the San
Gregorio vein to depth is being planned. There is a 300 metre
strike length of high grade mineralization on the San Gregorio vein
and a series of old workings by a previous operator follow the vein
another 450 metres WSW. Further to the WSW, the San Gregorio Vein
has been traced on surface for about one kilometre more, bringing
the total known strike extent to about two kilometres. Other
productive veins in the Topia District extend for 3 to 4 kilometres
along strike.
At the Rosario vein, development since the last update (GPR news
release January 26, 2009) includes further advance eastward on the
vein along the 1680 level, sub-level development, and a raise to
the old development on the 1710 level. The easternmost 100 metres
of strike along the 1680 level averaged 1,285g/t silver, 0.2g/t
gold, 7.05% lead, and 9.33% zinc over a 0.54 metre width. A
sublevel developed along a 70 metre strike length averaged 1,164g/t
silver, 0.23g/t gold, 6.69% lead, and 7.07% zinc over a 0.43 metre
width. The raise from the 1680 to 1710 level, a vertical distance
of 30 metres, averaged 1,421g/t silver, 0.09g/t gold, 7.99% lead,
and 8.09% zinc over the vein width of 0.21 metres. Including the
old 1710 level workings and the Company's new development, there is
approximately 300 metres of strike length of high grade
mineralization currently being developed on the Rosario Vein.
Along the Don Benito vein, development is ongoing from the main
access points at Crucero 9N (1420 level) and Dos Amigos (1500 and
1534 levels). Also, a new sublevel is in progress on the 1565
level, and raises have been completed from the 1420 to 1500 level,
1500 to 1534 level, and 1534 to 1585 level. Along much of the Don
Benito vein, the structure has split into two veins named Don
Benito North and Don Benito South. At depth, above the 1420 level,
the North and South veins merge back into a single vein. Presently,
most of the development is along the Don Benito North vein, as
infrastructure is put into place.
On the 1500 level, 170 metres of new development eastward along
the strike length of Don Benito North averaged 654g/t silver,
1.67g/t gold, 6.57% lead, and 12.33% zinc with a thickness of 0.56
metres. Parallel development, about 5 metres south, and along 100
metres strike of the Don Benito South vein averaged 977g/t silver,
3.82g/t gold, 14.4% lead, and 19.81% zinc with a thickness of 0.41
metres. On the 1534 level, new development along a 104 metre strike
length of the Don Benito North vein averaged 573g/t silver, 2.87g/t
gold, 14.8% lead, and 15.48% zinc with an average thickness of 0.61
metres. Development on the 1534 level of the Don Benito South vein
has not yet commenced pending the arrival of new underground
equipment.
A raise on the Don Benito North vein from the 1534 level to the
1565 sub-level along a 33 metre length averaged 527g/t silver,
3.64g/t gold, 14.16% lead, and 16.38% zinc over a width of 0.43
metres. On the 1565 sub-level, new development along 68 metres of
strike on the Don Benito North Vein averaged 564g/t silver, 1.55g/t
gold, 16.57% lead, and 6.86% zinc with a thickness of 0.23 metres.
New underground drill stations are being planned for the 1500 and
1585 levels to test the eastern extent of the Don Benito veins. A
ramp has been driven from the 1500 level to the 1470 level, and is
presently being developed to the east, to better establish access
for exploitation.
Given the narrow widths of the veins in the Topia District,
Great Panther is continuing to successfully use the resue mining
method to minimize dilution. This methodology, along with the high
grades of the mineralization, is resulting in an excellent profit
margin. A recent surface diamond drilling program, targeting a
number of veins, including San Gregorio and Rosario, has been
completed while underground drilling on the Don Benito vein is
ongoing. Assay results from drilling will be announced in the near
future.
All development on vein at Topia is systematically channel
sampled and the samples are assayed in the on-site laboratory for
gold, silver, lead, zinc, and iron. Monthly, a 5% random set of
pulps are assayed by SGS at the Company's Guanajuato Mine site
laboratory as duplicate quality control. All Topia Mine surface
sampling and drill core samples are assayed by SGS at the Company's
Guanajuato Mine site laboratory. Robert F. Brown, P. Eng and Vice
President of Exploration for the Company, is the Qualified Person
for the Topia Mine Project, under the meaning of NI 43-101, and has
reviewed these results. The Company's QA/QC program includes the
regular insertion of blanks and standards into the sample
shipments.
