Target
Epithermal Gold-Silver
Comments
The ore targets are large epithermal quartz and quartz-sulfide veins containing gold and silver. Recent sampling returns up to 700 g/t silver across a 2.5 m wide vein as well as disseminated gold in a silicified flow dome.
Business / Work Plan
Additional mapping and sampling are in progress.

Overview
The Company's wholly-owned Tembrao property is located in Rio Negro Province. It is a 6,000 hectare property located in the eastern part of the province, and is easily accessible by good roads and workable all year. The Company is currently engaged in a progressive mapping and sampling program the property.
Recent reconnaissance work included 50 chip-channel samples across the veins. Twenty-two of these samples contain >0.10 g/t gold and 14 contain >0.25 g/t gold. Nearly all of the samples contain anomalous amounts of silver, arsenic, molybdenum, copper, lead, or zinc. The highest value was a sample across a hydrothermal breccia containing multiple pulses of quartz veining, silicification, and brecciation. This was 2.5 m chip channel containing 1.76 g/t gold, 703 g/t silver, 0.76 % copper, and >1.0% lead.
The property covers an erosional window in younger basalts exposing what may be Jurassic age andesites and basalts. Alteration and mineralization is exposed over a distance of seven kilometers. On the west end the rhyolites include one area of strong silicification intermittently exposed for nearly 2,000 m in a northwest-southeast direction and nearly 1,000 m wide. This area crops out near the west end of the mineralized zone. On the east end is a strongly silicified rhyolite dome approximately 1,000 m in diameter. The crest of the dome is marked by two sub parallel quartz veins and breccias striking northwesterly.
Between the silicified rhyolites and the rhyolite dome are andesitic tuffs cut by several northeast striking quartz veins. The largest measures 1.5 to 6.5 m wide and is well exposed for more than 1,000 m. Both ends of this large vein are concealed by alluvial cover.
