Sendero Resources Corp. announced that drilling has commenced at its 100% owned Peñas Negras Project on the Vicuña Belt in La Rioja Province, Argentina.

Highlights
Diamond drilling has commenced for an initial program of 4,500m.
Four priority drill-ready porphyry/epithermal copper-gold targets have been selected for initial drill testing: La Peña, Tamberías, La Ollita and Cerro Verde South.
Drilling has commenced at La Peña with two planned holes at approximately 500m each.
A recent detailed ground magnetic survey at La Peña confirmed the large magnetic anomaly centered on the known porphyry and highlights a satellite magnetic anomaly to the north.
Many of the key geological, geochemical, and geophysical features seen at other deposits in the Vicuña Belt, such as Filo del Sol and Josemaria deposits are replicated in Sendero’s priority drill targets.
Sendero Executive Chairman, Michael Wood, commented:
“Drilling has commenced on schedule, and we are very excited to be drilling and now be able to gain a greater understanding of the multiple copper-gold porphyry and epithermal targets we have on the Peñas Negras project. We are starting at La Peña where the ground magnetics has confirmed in more detail the scale of the magnetic anomaly and also the potential for a satellite porphyry intrusive to the North”.
La Peña Ground Magnetics
La Peña is ranked as Sendero’s highest 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.
