multiple drill การใช้

• Several tries at drilling holes, first individually, then in a multiple drill-press proved that the concept was sound, but the production process was too costly.
• The Brigade Color Guard is separate from the Varsity Color Guard team and the Drill Team, which are considered quasi-sports teams that compete in multiple drill competitions in the Spring, with the first competition always taking place at Benedictine ( others are held throughout South Georgia ).
• Recognized mineralized zones were assayed using conventional fire assay with an atomic absorption or gravimetric finish, and at the end of the program, sample composites ( made by combining reject samples from multiple drill holes previously analyzed by conventional fire assay ) were made and sent to Lakefield Research for metallurgical testing.
