ZINC-SILVER-LEAD EXPLORATION: Sullivan-style deposit drilled in Idaho

IDAHO — Azteca Gold of Spokane, WA, says the mineralization at its Two Mile project appears to be a thick, Sullivan-type Precambrian massive sulphide occurrence with even higher grades that the famous mine to which it is being compared. The discovery was made near Osburn in Idaho’s historic Silver Valley.

 

Azteca reported in January 2009 that diamond drill hole 005A assayed 18.9% Zn, 3.6% Pb and 61.9 g/t Ag over 11.3 metres. Within that intersection, a 4.7-metre interval averaged 40.0% Zn, 7.4% Pb and 140.7 g/t Ag.

 

The Sullivan deposit near Kimberley, BC, was mined for over a century. It closed in 2001 after producing more than 130 million tonnes of ore at average grades of 6.9% Pb, 5.1% Zn and 67.0 g/t Ag. The deposit occurred as a broad, continuous and complex lenses approximately 2,000 metres in diameter and as much as 100 metres thick. It was emplaced by a sub-sea hydrothermal system, perhaps a black smoker, according to Azteca.

 

Also, similarly to the Sullivan deposit, the sulphides at Two Mile Creek contain gold, copper, gallium, germanium and indium.

Azteca has earned a 50% interest in the Two Mile project and created a joint venture with Silver Royal Apex. Additional information about the Two Mile project is posted at www.Azteca-Au.com.
