In addition, a 1.5% net smelter return ("NSR") is payable on the claims. Alternatively, Coro may acquire 0.5% out of this 1.5% royalty for US$2,000,000 at any time up to one year (12 months) following the start of commercial production on the property.In that case, a 1% NSR would remain on this property.

"We are very pleased to have signed this binding Letter of Intent and look forward to executing the definitive option agreement shortly," commented Coro CEO Luis Tondo. "Based on our district scale exploration, we consider the large Naguayan claim block to be very prospective for Marimaca type mineralization and the acquisition of this property forms part of our ongoing consolidation of mineral properties in the area, as per our longer term strategic plan."
