Sendero Resources Corp. announced that drilling has commenced at its 100% owned Peñas Negras Project on the Vicuña Belt in La Rioja, Argentina. La Peña Ground Magnetics: La Peña is ranked as Sendero's high priority target.

It has many typical features of Andean copper-gold porphyry deposits. The mineralised system is exposing at an optimum level of erosion, just above the interpreted high-grade copper-gold zone. Favorable features of the exposed diorite porphyry are intense potassic alteration, stockwork magnetite-quartz veining, and the presence of copper sulfides and oxides.

Two initial holes are programmed at La Peña. The recently completed detailed ground magnetic survey has confirmed the same shape and size of the strong magnetic response seen in historical airborne magnetic data centered on the known porphyry intrusive. The large discrete magnetic anomaly with potassic alteration measures approximately 800m long and 500m wide. Another magnetic anomaly located about 1000m to the north opens the possibility of a satellite porphyry system.

Ongoing Work Program: Regarding the recently completed geophysical surveys from the other priority targets, the company is awaiting results and will provide updates once all the information is received and processed for each target. Ground magnetics and induced polarization surveys have been completed at Tamberias and La Ollita and ground magnetics is being conducted at Cerro Verde South.
