The Fruta del Norte Epithermal Gold-Silver Deposit, South-East Ecuador

Diamond drilling since early 2006 has identified an epithermal gold-silver (Au-Ag) deposit beneath 140 m to >400 m of cover. The Fruta del Norte discovery had an inferred resource estimate of 58.9 Mt grading 7.2 g/t Au in October 2007. The mineralisation is hosted by Mid-Late Jurassic andesite and andesite porphyry in a regional fault zone beneath mainly post-mineral but in part syn-mineral Late Jurassic cover. The intermediate sulfidation-style deposit formed before and in part during deposition of epiclastic cover in the fault related pull apart basin. In addition to its size and obvious economic importance, the widespread occurrences of visible gold and exquisitely preserved epithermal textures will make Fruta del Norte an important learning tool for explorationists seeking epithermal mineralisation in theAndes and elsewhere.
