Geology of the San Cristobal Deposit

Dr. Buchanan earned his PhD in Economic Geology in 1979 and taught university level geology for several years before the romance of prospecting drew him back to the field. After several notable gold and silver discoveries, he capped his career in 2006 by winning the coveted Thayer Lindsley Award for the San Cristobal silver discovery. Larry will talk about that Discovery. He will also describe the transformation of the village and living conditions in San Cristobal. The village was sited atop the huge silver-gold deposit and had to be relocated 11 kilometers away. Larry and his wife Karen Gans have lived in the village and have documented the changes that occurred including a lift out of extreme poverty for hundreds of people. Their 2010 book is entitled the "Gift of El Tio" after the local god of the underworld who guards the mineral domain.
