Centauri Minerals Provides Field Update from Greater Exploration Portfolio in Northern Argentina Centauri Minerals Inc.

(TSX-V: CENT) (OTCQX: CNTIF ("Centauri" or the "Company") is pleased to provide a field update from recent exploration activities at its 100%-owned exploration portfolio projects in Northern Argentina. The current Phase 1 exploration drilling program at the Rio Grande gold-copper project ("Rio Grande") is the top priority for Centauri (see October 13, 2026 news release), but with the mandate for more new discovery opportunities, the exploration team has also commenced select activities for new drill target generation within Centauri's greater 40,000-hectare project portfolio.
Aguas Calientes project (gold and silver in Jujuy) – completion of a NS-AMT and gradient IP-resistivity geophysical survey over an area containing 6 km of well-mineralized float boulders, with goal of identifying drill targets for 2027.
Frontera project (silver and gold in Catamarca) – meeting with Minister of Mining of Catamarca government and initiated exploration restart process.
Catua project (copper oxides in Jujuy) – first field visit by new exploration team and renewal of environmental permits for future work.
Exploration team additions are supporting ramp-up of drilling at Rio Grande as Centauri's immediate priority, ongoing fieldwork initiatives for new drill targets across the 40,000-ha portfolio, as well as strengthening team to pursue and evaluate potential growth opportunities in Argentina
Sam Leung, Chief Executive Officer and Director of Centauri, commented:
"Beyond the ramp-up of exploration drilling at Rio Grande, Centauri is strategically advancing our prospective portfolio of earlier stage exploration projects in the active Northern Argentina mining region. Centauri's goal is to efficiently generate new drill targets, not just at Rio Grande, but across the portfolio for new discovery opportunities for our stakeholders. During Q3 and Q4 2026, Centauri expanded its exploration team with the addition of two Salta-based exploration geologists to support the Rio Grande drill program and portfolio-wide target generation. These new portfolio programs and exploration team additions also strengthen Centauri's presence and commercial advantages in the region for new growth opportunities".
Completion of Geophysical Program at Aguas Calientes
The Aguas Calientes project is located in Jujuy province, Argentina, approximately 35 km west of the town of San Antonio de los Cobres and in the region of the Aguilar (Grupo Integra) and Pirquitas mines (SSR Mining). In October 2026, Centauri completed a Natural Source Audio-Frequency Magnetotelluric ("NS-AMT") survey in conjunction with a Gradient Array Induced Polarization (IP) / Resistivity survey. The primary objective of the NSAMT survey is to characterize and map the distribution of the resistivity parameter within the designated project area, from near-surface levels down to depths of approximately 800 m. For the IP, the depth of investigation for resistivity and chargeability parameters is estimated at around 500 m.
Figures 1A and 1B show a summary view of the historical ground magnetics and a geological map of Aguas Calientes. The magenta polygon highlights the Silon zone, where the NS-AMT & IP geophysical survey has been completed. New dataset review and drill target generation work is ongoing, towards a potentially new drill program in 2027.
The geophysical program completed at Aguas Calientes was supported by the community of Puesto Sey in Jujuy province, which provided accommodation and catering to the field team, in line with Centauri's commitment to local procurement and community partnership.
Environmental Compliance, Field Work at Catua & Plans for Frontera
As a new company, Centauri continues to maintain environmental compliance for its exploration projects in Jujuy Province. In September 2026, the Company completed environmental participatory monitoring campaigns at the Aguas Calientes and Catua projects, and the renewal of the environmental permits (IIA) for both projects is in progress.
An initial site visit was conducted at the Catua project, where rocks from open trenches and surrounding outcrops were observed. There are small levels of sedimentary breccias, poorly exposed in the southern and western parts of the property. Copper mineralization on the property consists of copper coatings (patinas) on clasts in addition to a variety of copper oxides, including malachite, azurite, and chrysocolla as cement in conglomerates and poorly exposed sedimentary breccias. To date, no hypogene sulphide mineralization has been identified in the clasts described in the mineralized sedimentary units. The copper is interpreted to be either exotic (transported by low-temperature fluids) or sedimentary 'red bed' style. The Catua project remains at an early stage of exploration, and the team is reviewing the data to assess its potential.
At the Frontera project in Catamarca province, Centauri is updating the project's environmental permitting to align with the Company's planned exploration program. The updated submission is being prepared with the Company's environmental consultant and is expected to be submitted in the fourth quarter of 2026. In October 2026, Centauri representatives met with the Minister of Mining of Catamarca province to introduce Centauri, begin a working relationship with the provincial government, and advance the reactivation of exploration at the Frontera project.
The Frontera project is located close to the national border with Chile and has notable historical trench samples by previous owners that date back over 20 years. Highlights of the historical trench sampling include 8 m of 2,450.0 g/t Ag in the Gallega Zone, 50 m of 312.5 g/t Ag in the Central Zone, and 24 m of 208.0 g/t Ag and 22 m of 0.58 g/t Au in the Ixchel Zone. Limited drilling by previous owners in 2006–2007 intersected mineralization at depth, including 18 m of 0.59 g/t Au and 34.3 g/t Ag from 153 m in hole LFD-001 (including 4 m of 1.63 g/t Au and 385.5 g/t Ag from 167 m) and 5 m of 0.99 g/t Au and 52.6 g/t Ag from 48 m in hole LFD-008.
