Advertising and SDMG Sponsorship offers organizations with related interests and vendors the deepest possible association and reach with the Society and its members. We are pleased to provide the benefits of a simple advertising program in The Pegmatite, the Society’s bulletin with 10 issues published annually in full color (electronic format), or a tiered program, in which there are several levels of participation available, each offering a mix of different ad vehicles, marketing opportunities and branding benefits. The SDMG greatly values the support and contribution of its Sponsors. Their level of commitment and involvement with the Society helps create a mutually beneficial partnership.
