Mr. Yale Simpson, Chairman of the Company, commented, Rugbys approach at El Zanjon is designed to find an entire gold system, not just the odd vein.

Key Points: 
  • Mr. Yale Simpson, Chairman of the Company, commented, Rugbys approach at El Zanjon is designed to find an entire gold system, not just the odd vein.
  • Undoubtedly, the El Zanjon area has been ignored in the past due to the absence of outcropping veins.
  • Rugby is targeting major flexures within fault structures extending south from the Cerro Vanguardia mine to El Zanjon ( Figure 1 ).
  • Rugby is an exploration company conducting discovery stage exploration on targets in Colombia, Argentina, the Philippines and Australia.

Schaumburg, IL, March 24, 2020 (GLOBE NEWSWIRE) -- ETEL introduces the new Z3TM , a standalone motion platform that provides a surface with four degrees of freedom into a stacked architecture and is an alternative to piezoelectric solutions.

Key Points: 
  • Schaumburg, IL, March 24, 2020 (GLOBE NEWSWIRE) -- ETEL introduces the new Z3TM , a standalone motion platform that provides a surface with four degrees of freedom into a stacked architecture and is an alternative to piezoelectric solutions.
  • The Z3TM platform uses a combination of three flexures and a rotary module to provide rotary, Z-axis, and two oblique axis motions to a plate which can be anchored to a supporting table for multiaxial motion solutions.
  • The Z3TM allows for the migration from piezoelectric solutions, eliminating their hysteresis problems while supporting nanometer level resolution, accuracy, and repeatability at even higher dynamics.
  • As a leading international supplier of direct drive and motion control components and integrated systems, ETEL supports high tech industry with linear motors, torque motors, positioning stages, and motion controllers/systems.
