Sombrero Butte
The Sombrero Butte property land package represents the first consolidation of these claims since they were mined back in 1920. The target at Sombrero Butte is copper in breccias underlain by a subjacent porphyry target.
November 9 2006 - early assays include 48 meters of 1.06% Cu.
December 8 2006 - further assays including 22 meters of 4.74% Cu.
February 14 2007 - more high grade copper including 9.56 meters of 5.57% Cu including indicators of suspected buried porphyry source.
May 24 2007 - report further assays of high grade copper intercepts including 66 meters of 1.45%.
July 10 2007 - drilling extends copper mineralization.
February 28 2008 - drilling provides further high grade Cu mineralization and suggests footprint of potential underlying porphyry could be larger than first thought.
Van Dyke Copper Mine
The Van Dyke project contains 1100 acres of patented ground and was developed in the early 1900s when a shaft was sunk to a depth of 1692 feet. The mine produced 11.8 million pounds of copper between 1929 and 1945 from azurite, malachite, chrysocolla and tenorite ores grading just over 5.0 % Cu per ton. Between 1968 and 1980 Occidental Minerals drilled seventy exploration holes (sixty-two of which encountered measureable copper mineralization) on the Property. Forty-six of these holes were used to estimate a non-NI43-101 compliant, historical resource of 112,000,000 tons at a grade of 0.52% copper. These historical resources at the Property are to be used for geological purposes only. They have not been adequately reviewed by a Qualified Person to be reported as current resources and they cannot be relied upon. Metallurgical test work by Occidental indicated that between 70% and 80% of this copper could be recovered by means of in situ sulfuric acid leaching, with 3.8 pounds of acid being consumed per pound of copper produced.
