Challenger Exploration announced the results from first pass detailed geological mapping and rock chip sampling at the Colorado V concession in Ecuador. The surface mapping and sampling was designed to investigate two large soil anomalies believed to be the immediate strike extent of the recently announced bulk gold discovery which returned drill intercepts including 134 meters at 1.0 g/t gold and 4.1 g/t silver. Mapping and sampling have defined a 2-kilometer strike extent of high-grade gold and silver mineralization at surface with assays ranging from 14.35 to 0.1 g/t gold, 498 to 0.3 g/t silver. The mineralization, alteration, and structural controls to mineralization appear to be directly spatially related to the large soil anomalies. This extends the potential strike of the recently announced bulk gold discovery at Colorado V by 500% to 2.5 kilometers. The much broader zone of anomalous soil geochemistry to the south-east of CV1 and CV2 will also be the subject of follow-up. Discussion of results: The surface mapping and rock chip sampling program was designed to test south-east along strike from a 500-metre long zone defined by narrow underground workings where gold mineralization is currently being exploited on a small scale. The current owner of Colorado V concession had previously drilled several diamond core holes immediately along strike and down dip targeting extensions to this mineralization. These drill holes were not systematically logged or assayed for bulk tonnage gold or base metal mineralization. Complete sampling and assaying by CEL confirmed a bulk gold system surrounding these narrow veins with drill results including 144 meters at 1.5 g/t gold, 1.8 g/t silver and 151 meters at 0.9 g/t gold and 3.8 g/t silver. This mineralization does not appear to be traditional porphyry style mineralization with the gold associated with antimony, arsenic and to a lesser extent bismuth. It shows relatively little geochemical expression in soil, possibly masked by the larger gold-copper in soil anomalies believed to relate to gold-copper porphyry mineralization. The 500 meter strike extent defined by the underground workings and drilling, exhibits a strong antimony soil anomaly with a smaller coincident gold soil anomaly.
