GoldQuest Mining Corp. is pleased to announce an update on the district wide exploration of the Company's 100% owned Tireo Project surrounding their multi-million ounce Romero gold/copper deposit in the Dominican Republic.
The Project covers around 50 kilometres in strike length of the Tireo volcanic formation, only a small fraction of which had been subject to detailed exploration. GoldQuest geologists have been mapping and sampling the complete Project area for the past 12 months. This program has highlighted a corridor of alteration indicating mineralizing hydrothermal activity, as seen at Romero. The Company is following this up with an extensive ground geophysical survey employing induced polarization (IP) covering over 30 square kilometres that is in progress. With around a quarter of this survey's area covered, at least four new exploration targets considered worthy of drilling have been identified, which are shown on the map found here:
In the area surveyed to date, 17 grab samples returned over 1 g/t gold, with the highest sample returning 9.7 g/t gold.
GoldQuest's Chairman Bill Fisher commented, "Our new exploration targets display a number of similarities to our 2012 Romero discovery, which was discovered by drilling targets generated by the first IP program deployed in the region. The new IP survey has made a great start and we look forward to reporting on further results as the program unfolds, as the areas with the greatest extent of intense argillic alteration have yet to be surveyed. GoldQuest has always stressed the importance of the Tireo trend as a potential "mining camp" capable of hosting multiple deposits. We view the results of the ongoing program as the roadmap to potential new discoveries. "
"The targets highlighted in this release are in areas of deeper erosion which created surface exposures of the target rock types and areas of intense alteration, some of which report highly anomalous gold results from grab samples. This direct evidence, at surface, rather than "blind" and at depth as at Romero, increases our confidence in the potential for further discoveries," commented Julio Espaillat, GoldQuest's President & Chief Executive Officer.
The list of characteristic features below have been identified at Romero, and are clearly visible in these new targets. This set of features suggests potential for new discoveries of similar styles of mineralization.
- Gold and/or copper at surface, particularly in dacite and andesite volcanics
- Magnetic lows - hydrothermal fluid movement destroys the surrounding rock's magnetism.
- Argillic alteration -evidence of hydrothermal fluids "cooking" the surrounding rocks.
- High Chargeability - shows the plume of sulphides within which lies the highest potential for gold/copper - this is the technique that discovered Romero.
- High resistivity - shows the area where silica creates a resistive core to a chargeability high -- very distinctive at Romero.
- Rhyolite domes in the area - evidence of volcanic activity possibly related to metals emplacement.
A continuous high chargeability trend along magnetic lows has emerged from the current survey with four distinct zones of even higher chargeability values. The trend and the higher chargeability zones within it are clearly visible as areas of red and pink shading on the map found here:
The map also displays approximate boundaries of intense argillic alteration showing the clear spatial correlation between alteration at surface and areas of underlying high chargeability. All four high chargeability zones are 500 metres or more in length and up to 200 metres in width, with a high resistivity signature coincident with the high chargeability. They also display anomalous gold and copper in grab samples, argillic alteration and adjacent rhyolite domes. These are characteristic features of the area surrounding the Romero deposit which has high concentrations of chalcopyrite, a copper sulphide, gold and quartz (silicification). The high silicification areas of Romero are correlated to the highest gold grades.
IP surveys and other ground exploration are continuing southwards through the Tireo Project. The Company will issue further news on other new discovery areas and exploration results as they become available.
