Alan Brown, CEO of Tombstone Exploration, remarked, "We have engaged Layne Christensen to conduct the previously announced extensive drilling program as a follow up to our filing of the N.I. 43-101. The drill program will focus on the areas that have been determined to have the greatest potential for significant silver deposits. We are excited to get the drill program going, particularly in light of silver prices continuing to rise. A start date for drilling will be announced shortly."
