Name: Topia mine.

Location: The Topia property is located in the heart of the Topia mining district, in west-central Durango state, Mexico.

Controlling Company: Great Panther Silver holds a 100% interest in the property through its wholly owned Mexican subsidiary, Minera Mexicana El Rosario.

Brief History: The deposits in the Topia area have been mined intermittently since the sixteenth century. Great Panther bought the property in 2005, refurbished and recommissioned the mill, rehabilitated underground workings and resumed operations. The mining group has conducted exploration and continues to explore the property.

Brief Description: The Topia property comprises several small underground silver/lead/zinc mines in and around the town of Topia and a 275 t/d processing plant.

Geology/Mineralisation: The Topia mineral deposits are hosted in steeply dipping east-northeast-striking fault zones. These fault zones are typically narrow, with an average width of about 30 cm. The widest faults are in the Argentina system, where they are up to 3 m wide and accompanied by gouge and intense clay alteration. They are broadly curvi-planar in shape along strike and downdip, but more or less straight over short, stope-length distances.

Displacements across these structures are thought by mine geo- logists to be from 50 m to 100 m, in a normal sense, with some rotational component. The faults branch and anastomose in a classic brittle fracture pattern commonly seen in narrow vein settings. Shoots pinch and swell along the trends, but the host structures themselves are observed to be very continuous. The main structures have been traced for as long as 4 km.

GPR is carrying out or has recently carried out exploration and development work and is mining on several of these structures.

Mineralisation within the veins consists primarily of massive galena, sphalerite, and tetrahedrite in a gangue of quartz, barite, and calcite. The vein constituents often include adularia and sericite, and the wider fault zones contain significant proportions of clay as gouge and alteration products. Ore minerals occur as cavity-filling masses, comprising millimetre-scaled crystals of galena and sphalerite. No definitive metal zoning has been discerned, but the lower parts of the mines are reported to contain higher gold content than those at higher elevations.

The veins range in thickness from a few centimetres to 3 m. They are very continuous along strike, with the main veins extending more than 4 km. The Madre vein has been mined for 3.5 km and the Cantarranas vein for 2.4 km. Many of the other veins have been mined intermittently over similar strike lengths. Vertically, the veins grade downward to barren coarse-grained quartz-rich filling and upwards to barren cherty quartzcalcite-barite vein filling. The main host rock is andesite of the Lower Volcanic Series, which is usually competent, making for generally good ground conditions within the mine. In wider sections, with greater clay content and/or zones of structural complexity, ground conditions are less favourable.

Resources: Total measured and indicated resources as at 2013 were 156 000 tonnes at 806 g/t silver, 1.47g/t gold, 6.48% lead and 4.29% zinc. Total inferred resources were 273 000 t at 837 g/t silver, 0.8 g/t gold, 5.7% lead and 3.9% zinc.

Products: Silver/gold/lead/zinc.

Mining Method: The Topia silver/gold/lead/zinc mines are small, narrow-vein, underground operations using a modified cut-and-fill mining method known as resuing. In the wider veins, mining is by mechanised cut-and-fill mining.

Major Infrastructure and Equipment: The physical plant site includes crushing, grinding, flotation and dewatering, the tailings storage facility, the mine workings and associated facilities, a coarse ore bin, the main ventilation fan, workshops, warehouses, administration buildings, and dry facilities.

Facilities providing basic infrastructure to the mine comprise electric power from the national power grid, heat, water supply from artesian springs and sewage treatment.

Underground infrastructure includes drifts, sublevels, ramps, raises and a mobile equipment fleet.

Access to the mine is by roads.

Prospects: The processing plant has been upgraded by the installation of a new cone crusher. This will increase crushing capacity at the plant, reduce the ore feed size to the mill and maintenance costs. In addition, various overhead cranes have been installed at the processing plant to facilitate maintenance activities and increase efficiencies.

The Topia tailings dam is undergoing a geotechnical study, including geological, geophysical and soil mechanics surveys, aiming to provide guidance for an increase in the tailings pond capacity. This study is expected to be completed in the first quarter of 2014.
