VANCOUVER, BRITISH COLUMBIA--(Marketwired - May 14, 2013) - GREAT PANTHER SILVER LIMITED (TSX:GPR)(NYSE MKT:GPL) ("Great Panther"; the "Company") today announced the appointment of Mr. Geoff Chater to its Board of Directors, effective immediately, and the recent addition of two senior personnel to the management team in Mexico.

Mr. Chater holds a B.Sc. in Geology and has more than 24 years of experience in the mineral and mining industries operating in North America, South America and Africa. He is the principal of Namron Advisors, a consultancy that provides corporate strategy, transaction related business development and capital markets relationship development, financing and communications advice. Recently he served as President of Valley High Ventures Ltd., and from 1999 to 2008, he was Manager of Corporate Relations for First Quantum Minerals Ltd. Prior to joining First Quantum he held positions with Nevada Pacific Gold Ltd., Eldorado Gold Corporation, Ivanhoe Capital Corporation, Fairbanks Gold Ltd. and Cornucopia Resources Ltd. He is currently a Director of Bearing Resources Ltd., Kiska Metals Ltd., Lara Exploration Ltd., Luna Gold Corp. and Reservoir Minerals Inc.

Recently joining the Great Panther Senior Management Team in Mexico is Mr. Juan Manuel Flores, Vice President, Operations and Mr. Cesar Epifanio, Vice President, Safety, Health and Environment (SH&E). Both executives are based in Guanajuato. Mr. Flores has over 35 years of industry experience and holds a B.Sc. in Mining and Metallurgical Engineering and a Master of Science, Mineral Economics. Mr. Epifanio has a long history of success in SH&E with multi-national companies and holds a degree in Industrial Engineering with an additional degree in Health and Safety. Great Panther's Mexican subsidiary was recently awarded the distinction as a "Socially Responsible Company" by CEMEFI (Centro Mexicano para la Filantropia), for a third consecutive year and is committed to maintaining this status.
Mr. Chater's addition to the Board will provide increased depth in the mining industry with particular emphasis on the capital markets sector. Mr. Flores and Mr. Epifanio have already strengthened the in-country management team that oversees Great Panther's existing operations and will take San Ignacio into production next year in a socially and environmentally responsible fashion with safety of our personnel as our number one priority.

VPG Releases Improved Bulk Metal® Power Current Sensing Resistors With 3 A and 15 A Maximum Current, TCR to 15 ppm/deg. C, Resistive Tolerance to 0.1%, and Four Leads for a Kelvin Connection

Devices Offered in Two Configurations for Medium-Power Current Sensing and Low-Ohm, High-Power Resistive Shunt Resistors

MALVERN, PA--(Marketwire - November 29, 2010) - Vishay Precision Group, Inc. (NYSE: VPG) today announced that its Vishay Foil Resistors division has released three improved Bulk Metal® power current sensing resistors with TCR of 20 ppm/deg. C (available to 15 ppm/deg. C), resistive tolerance to 0.1%, load life stability of 0.5% at +25 deg. C for 2000 hours at rated power, and four leads for a Kelvin connection. Available in two configurations, the VCS101 and VCS103 serve as medium-power current sensing resistors, while the VCS401 is optimized as a low-ohm, high-power resistive shunt.

The VCS101 and VCS401 offer power ratings of 1 W at 25 deg. C and a 15 A and 3 A maximum current, respectively, while the VCS103 features a 1.5 W power rating and 15 A maximum current. All devices feature a resistance range from 0.005 to 0.25 ohms. Vishay Foil resistors are not restricted to standard values and specific "as required" values (e.g. 0.123 ohms vs. 0.1 ohm) can be supplied at no extra cost or delivery.
The devices released today feature a maximum operating temperature of +175 deg. C, a rise time of 1.0 ns, with effectively no ringing, thermal EMF of 0.1 microvolt/deg. C typical, and a voltage coefficient of less than 0.1 ppm/V. The VCS101, VCS103, and VCS401 offer a non-inductive, non-capacitive design to minimize hot spots.

Typical end for the resistors will include battery chargers, current regulators, dc-to-dc converters, electronic scales, motor controls, power tools, power supplies, pressure sensors, and voltage regulators in military/aerospace, medical, and industrial applications.

The need to measure the flow of current in electronic systems is becoming increasingly widespread. Reasons for this include the growth of portable, battery-powered products, which increase the need to minimize energy usage and improve efficiency. The drive for more features and less frequent recharging has led to lithium-ion, with its superior energy density, becoming the preferred technology. The task of charging a lithium-ion battery is, however, more demanding than for earlier types. This has given rise to the development of charger controller ICs, which regulate the current and voltage within the tight limits required.

There are two problems traditionally associated with using a resistor to measure current: temperature sensitivity at high currents and long thermal stabilization time when power changes. Vishay Foil Resistors' current sensing devices tackle both of these problems. Current sensing is best achieved with a Kelvin connection, as featured with the VCS101, VCS103, and VCS401, which removes the unwanted influences of lead resistance and lead sensitivity to temperature. A Kelvin connection reduces, especially for low ohmic resistance values, measurement errors due to the resistance of the lead wires and the solder joints as the sensing is performed inside the resistor, in or close to the active resistive element.

Of the commonly used methods of measuring the magnitude of electrical current, this current sensing resistor method provides the most precise measurement. According to Ohm's law, V = IR, the voltage drop measured across a resistor is proportional to the current flowing through the resistor. With the known value of the resistance R, the voltage drop sensed on the resistor indicates the intensity of the current flowing through it.

Assuming an ideal current sense resistor that doesn't change its resistance value when there is a change in the magnitude of the current or a change in environmental conditions, like the ambient temperature or self heating, the measured voltage drop will yield a precise value of the current: I = V/R. But with a real-life resistor, such as a metal film resistor, a change in current intensity (and in the dissipated power) will cause a change in the resistor's value, which will involve a thermal transient period taking a few seconds or longer to stabilize. Therefore, the key to a fast and precise measurement of current is the use of a real-life current sensing resistor like the VCS101, VCS103, or VCS401, which approach, as closely as possible, an ideal resistor. That is, a resistor that is not influenced by changes in the magnitude of the current flowing through it, or by changes in ambient temperature or any other environmental condition.

Samples and production quantities of the new current sensing resistors are available now, with lead times of five days for samples, and eight weeks for standard orders.
