SENDERO RESOURCES RECEIVES DRILL PERMITS FOR PENAS NEGRAS PROPERTY

Sendero Resources Corp. has received drill permits for its Penas Negras project on the Vicuna belt in La Rioja, Argentina.

This is a major development for the company as it represents the successful conclusion of the company's permit application process to secure the drill permits which now enables the company to drill test several high-priority porphyry targets, where similar geology has been discovered to the major deposits on the Vicuna belt. None of the priority targets have previously been drill tested.

Highlights:

• Fully permitted for drilling which will commence in January, 2024, with an initial 4,500 metres of diamond drilling;
• Three priority drill-ready porphyry copper-gold targets have been selected for initial drilling, including La Pena, Cerro Verde South and Tamberias;
• Many of the key geological, geochemical and geophysical features seen at other deposits in the Vicuna belt, such as the Filo del Sol and Josemaria deposits, are replicated in these priority drill targets.

Michael Wood, Sendero executive chairman, commented:

"This is a very significant development for Sendero which validates the support of the La Rioja provincial government for the company to advance the Penas Negras project. Drilling will commence in January, 2024, to test multiple attractive copper-gold targets with similar geological characteristics to the neighbouring deposits on the Vicuna belt."

La Pena target

La Pena is ranked as the highest-priority drill target in the Penas Negras portfolio due to:

1. The remarkable coincidence and intensity of all the favourable geological, geochemical and geophysical features typical of Andean Cu-Au (copper-gold) porphyry deposits;
2. The apparent optimum level of erosion exposing the mineralized system just above the interpreted high-grade Cu-Au zone.

Cerro Verde South target

Extensive porphyry-related alteration coincides with a major magnetite-quartz stockwork zone. In the same area, highly anomalous Cu-Au-Mo (copper-gold-molybdenum) with a peripheral Zn-Pb-Cd (zinc-lead-cadmium) halo was defined by ionic leach and talus fines geochemistry. These favourable features also coincide with a magnetic high. The target has not been previously drilled.

Tamberias target

Tamberias comprises an outcropping diorite porphyry with classic porphyry-style quartz-magnetite veining. Pervasive hydrothermal alteration is zoned from a potassic core overprinted chlorite-epidote. The area shows anomalous Cu-Au-Mo geochemistry in ionic leach soils, and peripheral Zn-Cd-Pb coinciding with a magnetic high and quartz vein stockwork zone. Tamberias represents a valid untested drill target and has all the hallmarks of a high-level, telescoped Cu-Au porphyry system.

About Sendero Resources Corp.

The company is focused on copper-gold exploration at its 100-per-cent-owned Penas Negras project in the Vicuna belt in Argentina. The Penas Negras project has similar geological characteristics to other deposits in the Vicuna belt, and a cluster of porphyry and epithermal targets have been identified on the project. The company, through its wholly owned subsidiary, Barton SAS, is the holder of 10 mining concessions covering 120 square kilometres in the province of La Rioja, Argentina. The company has an experienced management and exploration team which will use their expertise and operational knowledge to advance the multiple targets across the project.
