December 11, 2007 Reported to have completed to date a total of 4,375 meters (14,350 feet) of drilling in 17 core holes has been completed. The results from the exploration have been encouraging to plan follow up work.
During 2004, Barrick spent approximately $0.65 million on geologic mapping, geochemical and geophysical surveys and drilling on the Puchuldiza property which brings their cumulative expenditure to $1.91 million. Barrick drilled 10 core holes in 2004 for a total of 2,123 meters (6,965 feet).
Geologic resource estimates calculated to date (as of Nov/01) at Puchuldiza range from 492,000 ounces of gold to 983,000 ounces of gold depending on various cut-off grades and price assumptions. Preliminary work has indicated the possible existence of a large high-grade feeder system at depth underlying the near-surface mineralization.
In 2002, Barrick conducted geologic mapping plus other numerous geochemical and geophysical techniques on the property. Drilling is expected to commence during the first quarter of 2003.
November 28, 2001 Coeur d'Alene has signed an exploration agreement with Barrick Gold covering Coeur's Puchuldiza gold property in northern Chile. Puchuldiza is considered to be geologically unique in Chile in that it appears to be a large
epithermal hot spring deposit in a setting similar to other high-grade gold deposits in the U.S., New Zealand and Japan. Under the terms of the agreement, Barrick can earn a 75% interest in the property for exploration expenditures of US$2.25 million over the next five years with an option to increase intersest to 85%. Geologic resource estimates calculated to date at Puchuldiza range from 492,000 ounces of gold to 983,000 ounces of gold.
