Silver Queen Property, Arizona

Overview

The Silver Queen claims were staked by Cardero based on examination of historical reports and data that led to the delineation of a prospective area, covering favourable geology and geophysical anomalies that do not appear to have been drill tested. The same rock types that are host to disseminated oxide copper at Zonia have been mapped on the Silver Queen block. Structural evidence suggests these rock units repeat themselves in a fold limb dipping to the southeast. This interpretation is corroborated by a 400 by 2700 metre aeromagnetic low parallel to the Zonia deposit, which was interpreted to be due to magnetite-destructive alteration and possibly mineralization at depth. However, subsequent geophysics and project-wide rock geochemical sampling have shown there is low probability of porphyry copper mineralization in the area.

There are numerous old adits, pits and shafts on the claims, which are evidence of historically exploited high-grade copper bearing structures (Money Maker, Silver Eagle, Silver Bell, Surprise) near the northeast end of the claim block, in addition to the small, past-producing Silver Crown silver mine (not on the claims). This structurally controlled mineralization remains to be evaluated for potential significance. Similar historical high-grade copper workings also occur on the Zonia property (e.g. Copper Crown mine) and remain to be evaluated.
