SENDERO RESOURCES REPORTS FINAL ANALYTICAL RESULTS FROM 2024 DIAMOND DRILLING

CAMPAIGN AT THE PEÑAS NEGRAS PROJECT IN THE VICUÑA DISTRICT, LA RIOJA ARGENTINA

Vancouver, British Columbia – (October 10th, 2024) – Sendero Resources Corp. (TSXV: SEND)

(“Sendero” or the “Company”) is pleased to announce results of the last two diamond drillholes

from its maiden drilling program at its 100% owned Peñas Negras Project in the Vicuña District in La

Rioja, Argentina.

Highlights

• PNDH007 (La Ollita) intersected porphyritic diorite with pervasive quartz-sericite-chlorite

alteration. Hole abandoned at 95 m in-hole depth due to intense fracturing which

precluded continuation of drilling. No significant assay results.

• PNDH008 (La Ollita) intersected andesite and diorite porphyry with pervasive propylitic and

phyllic alteration. Analytical results indicate geochemically anomalous Au and Ag from

surface to approximately 20 m in-hole depth, corresponding with argillic alteration. Copper

is geochemically anomalous below the contact between argillic alteration and underlying

phyllic alteration.

About the Project

The Vicuña is a Miocene metallogenic belt in the southern Cordillera which links the prolific El Indio

and the Maricunga Belt. Both porphyry (Cu-Au-Ag-Mo) and epithermal (Cu-Au-Ag) styles of

mineralization are known at large scale (>550Kt Cu, 40t Au), including Filo del Sol (Filo Mining,

TSE:FIL), Josemaria (Lundin, TSE:LUN), and Los Helados (NGEX, TSE:NGEX), and Caserones (Lundin) in

the vicinity.

The Peñas Negras project comprises 120km2 mineral claims in the Vicuña Belt, where previous work

has outlined several Cu and Au anomalous showings and prospects. Exploration work by Sendero

included airborne magnetics and gamma spectrometer survey, IP/Resistivity, soil geochemistry,

geological mapping, which culminated in a 3126 m diamond drilling programme in eight holes

testing 3 target areas.

Analytical results from drill holes PNDH001 to PNDH006 have been previously disclosed in press

releases 03 April 2024 and 1 May 2024.

Hole PNDH007 targeted a NW trending local magnetic anomaly and an interpreted fault zone.

Drilling intersected unconsolidated glacial moraine from collar to 38.5m in-hole depth, and highly

fractured porphyritic diorite with pervasive quartz-sericite-chlorite alteration and magnetite-pyrite

in veinlets and disseminations with minor chalcopyrite mineralization. From 77.8m in-hole depth,

drilling encountered fault breccia zone which increased the difficulty of drilling, and the hole was

abandoned at 95m in-hole depth.

Analytical results indicate no significant mineralization.

Hole PNDH008 was targeted on an isolated strongly magnetic body. Drilling collared directly in

bedrock with no overburden, and intersected primarily andesite and diorite porphyry rocks. Strong

faulting and brecciation resulted in abandoning the hole at 88m in-hole depth.

Laboratory analysis indicates geochemically anomalous Au and coincident Ag from surface to

approximately 20m in-hole depth, which marks the base of the argillic alteration. Below the argillic

alteration Cu is geochemically anomalous in the phyllic alteration.

About Sendero Resources Corp.

The Company is focused on copper -gold exploration at its 100% owned Peñas Negras Project in the

Vicuña Belt in Argentina. The Peñas Negras Project has similar geological characteristics to other

deposits in the Vicuña Belt and several porphyry and epithermal targets have been identified on the

project. The Company, through its wholly owned subsidiary, Barton SAS, is the holder of ten granted

mining concessions covering 120 km2 in the province of La Rioja, Argentina. The Company also has an

option agreement to earn 80% interest on eight granted mining concessions covering 91.7 km2

adjacent to the East of the Peñas Negras Project.
