Key Highlights
- Centauri Minerals completed geophysical surveys at Aguas Calientes in Jujuy to generate 2027 drill targets.
- Centauri began steps to restart exploration at Frontera in Catamarca after meeting provincial mining officials.
- Centauri conducted an initial field visit at Catua in Jujuy and is progressing environmental permit renewals.
Centauri Minerals Inc. (TSXV: CENT) (OTCQX: CNTIF) provided a field update on exploration work across its 100%-owned portfolio in Northern Argentina, alongside its ongoing Phase 1 drilling program at the Rio Grande gold-copper project.
The company said it has started select work aimed at generating new drill targets across its broader roughly 40,000-hectare land package, while continuing to prioritize drilling at Rio Grande.

Aguas Calientes geophysics and 2027 target work
Centauri reported that it completed a Natural Source Audio-Frequency Magnetotelluric survey and a Gradient Array Induced Polarization/resistivity survey at its Aguas Calientes project in Jujuy province in October 2026. The company described the work as covering an area that includes about 6 kilometres of mineralized float boulders, with the aim of identifying drill targets for 2027.
According to the release, the magnetotelluric survey is intended to map resistivity from near surface to depths of about 800 metres, while the induced polarization program is estimated to investigate to around 500 metres for resistivity and chargeability parameters. Centauri said it is reviewing the new datasets and continuing drill target generation work.
Catua field visit and environmental permitting
At the Catua project in Jujuy, Centauri said its new exploration team completed an initial site visit and observed rocks from open trenches and nearby outcrops. The company described copper mineralization as coatings on clasts and copper oxides including malachite, azurite, and chrysocolla, and said no hypogene sulphide mineralization has been identified to date in the clasts described in mineralized sedimentary units.
Centauri said the copper is interpreted as either exotic (transported by low-temperature fluids) or sedimentary red-bed style, and that Catua remains at an early stage while the team reviews data to assess potential.
Separately, Centauri said it completed environmental participatory monitoring campaigns at Aguas Calientes and Catua in September 2026, and that renewal of environmental permits (IIA) for both projects is in progress.
Frontera restart planning and historical results
For the Frontera project in Catamarca province, Centauri said it is updating environmental permitting to align with its planned exploration program, with an updated submission expected in the fourth quarter of 2026. The company also said its representatives met the Minister of Mining of Catamarca province in October 2026 as part of efforts to reactivate exploration.
Centauri highlighted historical trench sampling by previous owners at Frontera, including 8 metres of 2,450.0 grams per tonne silver in the Gallega Zone, 50 metres of 312.5 grams per tonne silver in the Central Zone, and 24 metres of 208.0 grams per tonne silver plus 22 metres of 0.58 grams per tonne gold in the Ixchel Zone. The release also cited limited drilling by previous owners in 20062007, including an interval in hole LFD-001 of 18 metres of 0.59 grams per tonne gold and 34.3 grams per tonne silver from 153 metres (including 4 metres of 1.63 grams per tonne gold and 385.5 grams per tonne silver from 167 metres), and 5 metres of 0.99 grams per tonne gold and 52.6 grams per tonne silver from 48 metres in hole LFD-008.
The company said the scientific and technical information in the release was reviewed and approved by Dr. Kevin B. Heather, Technical Advisor to Centauri Minerals, as a qualified person under National Instrument 43-101.
