Valls Geoconsultant (VG) is offering a quality assurance program for the field sampling procedures which include collection, labeling, and shipping components. VG also has established a series of procedures for logging and general mapping. This is especially important in larger projects, where more than one geologist is doing field descriptions. P. Geo.
