NEWS RELEASE SEPTEMBER 02, 2025
HANNAN EXPANDS PREVISTO GOLD PROSPECT FOOTPRINT BY 2.1 KM
Vancouver, Canada -- Hannan Metals Limited's ("Hannan" or the "Company") (TSXV: HAN) (OTCPK:
HANNF) is pleased to announce the i dentification of a new gold zone at Honda Creek, located 1.3 km to 2.1
km south-southwest of the Previsto Central prospect at its 100% owned Valiente project in Peru.
Key Points:
1. Significant New Gold Zone Identified: A substantial 2 km x 0.8 km gold anomalous zone has
been discovered at Honda Creek, located 1.3 km to 2.1 km south -southwest of the Previsto Central
prospect. At Honda Creek rock chip samples returning up to 0.92 g/t Au and soil samples up to 0.70
g/t Au, representing a major expansion of the known mineralized footprint beyond Previsto Central.
2. Gold-Focused System in Sedimentary Host Rocks: The Honda Creek zone demonstrates gold-only
mineralization (all samples <500 ppm Cu) predominantly hosted within the Chonta Formation limestone
and siltstone units with small scattered intrusives, indicating a different mineralization style that
complements the alkaline intrusive- hosted epithermal system at Previsto Central located 1.3 km to 2.1
km north-northeast.
3. Extensive Surface Sampling Confirms Mineralization : Systematic sampling confirms widespread
gold anomalism across the entire 1.6 km² area.
4. Strategic Expansion of District -Scale System : The Honda Creek discovery extends the greater
Previsto mineralized system to over 5 km in strike length, reinforcing the district-scale potential of this
emerging gold camp and providing multiple exploration vectors for future drill targeting.
5. Validates Exploration Model Beyond Porphyry Hosts: The identification of gold mineralization
within sedimentary Chonta Formation rocks demonstrates that mineralization extends beyond the K -
feldspar porphyry-hosted zones, significantly expanding the prospective ground within the Company's
1,002 km² land package.
Michael Hudson, CEO, states: "The first results from the new Honda Creek area represent a significant
expansion of our Previsto gold system. Finding this extensive 2 ,000 m by 800 m gold zone in predominantly
sedimentary host rocks, distinct from our alkaline epithermal mineralization at Previsto Central, demonstrates
we're dealing with a multi-phase, district-scale gold system.
“The gold-only signature and limestone host rocks suggest potential for carbonate replacement or sediment -
hosted gold mineralization styles, adding an entirely new dimension to our exploration model. With surface
samples returning up to 0.92 g/t Au across this vast area, we're seeing the hallmarks of a major gold district
emerging. This discovery, combined with our advancing drill program at Belen and the systematic expansion at
Previsto Central, positions Hannan at the forefront of one of Peru's most exciting new gold frontiers."
“We're looking at a vast 'sea of gold' opportunity. Our next exploration campaigns have strategically focused on
our high-grade areas where sampling has discussed 26.0 m @ 5.4 g/t Au, specifically designed to expand known
zones and systematically identify high-grade mineralization trends within this emerging gold district (Figure 2).”
Technical Discussion
Honda Creek Gold Mineralization
The Honda Creek area represents a new gold discovery located 1,300 m to 2,100 m south -southwest of the
Previsto Central high- grade gold zone. This find substantially expands the known mineralized footprint of the
greater Previsto district and introduces a potentially different style of gold mineralization to the project.
Geological Setting and Mineralization Style
Unlike the K-feldspar porphyry-hosted alkaline epithermal system at Previsto Central, the Honda Creek zone is
predominantly hosted within the Chonta Formation, consisting of limestone and siltstone units with scattered
small intrusive bodies. This geological setting suggests potential for:
• Carbonate replacement-style mineralization where gold-bearing fluids have preferentially replaced
favorable limestone horizons
• Sediment-hosted gold systems similar to Carlin-type deposits
• Contact-related mineralization associated with the small intrusive bodies scattered throughout the
area
The exclusively gold-focused nature of the mineralization, with all rock samples containing less than 500 ppm
copper, distinguishes this zone from typical porphyry-related systems and suggests a gold-specific mineralizing
event.
Sampling Results and Distribution
The systematic sampling program at Honda Creek has defined a substantial 2,000 m x 800 m gold anomalous
zone through multiple sample types:
Rock Chip Sampling: 81 rock chip samples collected across the zone returned gold values ranging from 0.002
g/t to 0.92 g/t Au and averaging 0.09 g/t Au. The distribution of anomalous samples throughout the entire
area indicates widespread mineralization rather than isolated occurrences.
Channel Sampling: Four channel samples (CH16701, CH16719, CH16721, CH16724) with a cumulative length
of 11.9 m were collected to test mineralization continuity. While returning lower grades (0.0 3 to 0.14 g/t Au),
these channels confirm the pervasive nature of gold mineralization across different structural orientations.
Soil Geochemistry: 26 soil samples returned anomalous gold values ranging from 0.03 g/t to 0.70 g/t Au
and averaging 0.12 g/t Au . The elevated gold in soils across this large area provides strong evidence for
underlying bedrock mineralization and defines clear vectors for follow-up exploration.
Implications for District-Scale Potential
The Honda Creek discovery significantly enhances the district-scale potential of the greater Previsto area by:
1. Expanding the mineralized footprint from the known 3 km x 3 km area at Previsto Central to a
district spanning over 5 km in strike length
2. Demonstrating multiple mineralization styles within a single district, increasing the potential for
multiple deposit types
3. Validating the exploration model in sedimentary host rocks, dramatically expanding the prospective
ground within Hannan's land package
Next Steps at Honda Creek
The Company plans to advance the Honda Creek discovery through:
• Detailed geological mapping to understand structural controls on mineralization
• Systematic channel sampling of available outcrops
• Integration with the upcoming Previsto drill permit application
Drill Permitting in Previsto (DIA Amanecer)
A ten-person environmental team including professional environmental archaeological investigations, community
workshops and liaison activities has now completed collecting appropriate information necessary to make the
submittal for approval to the DGAAM - General Directorate of Mining Environmental Affairs - of the Ministry of
Energy and Mines, Peru. The work program includes:
• Environmental baseline monitoring for the project, conducted by third party experts (now complete);
• Submission to the Peruvian Ministry of Culture the CIRA (Certificate of non- existence of archaeological
remains) which declares that the project does not impact archaeological sites;
• Public participation meetings outlining Hannan’s exploration plans will be held in the hamlets of Nueva
Palestina, Inca Garcilazo, Chancadora and Previsto, where the communit ies are on record as approving
the company’s proposed drill program;
The DIA is the primary environmental certification required to allow low impact mineral exploration programs,
that includes drilling programs, to proceed in Peru.
About the Valiente Project
The 100% owned Valiente project is in central eastern Peru, east of the city of Tingo Maria (Figures 1 and 2).
The area is characterized by steep topography on the eastern flank of the Central Cordillera with elevations
between 800 m and 2,000 m above sea level (a.s.l.). The project was found in 2021 during an extensive
greenfields prospecting program initiated by Hannan for back-arc porphyry copper-gold systems. The Company
has been actively prospecting on the project since 2021 and has successfully gained social permits progressively
in all areas of interest.
During 2021 Hannan staked and still holds 1,002 km 2 of 100% owned mining concessions at Valiente covering
unexplored terrain for potential mineralized porphyry targets in central eastern Peru. The Valiente Project has
rapidly evolved from a greenfields prospect to a multi-prospect opportunity.
Early surface prospecting identified two outcropping copper-gold porphyry targets and one epithermal target at
Belen (see Press Release Feb 16, 2023). Porphyry areas quickly followed at Serrano Norte, Serrano and
Pucacunga. The focus more recently has been on Previsto. At Previsto and Belen, a district-scale porphyry cluster
within an area of 25 km by 10 km, with eight porphyry and/or epithermal targets now identified in more detail
with up to 10 earlier stage targets awaiting further work.
The company is executing a multi-year strategy to systematically explore and drill test its extensive land package
in this emerging Miocene-aged, linked porphyry-epithermal mineral belt.
Technical Background
All samples were collected by Hannan geologists. Samples were transported to ALS in Lima via third party
services using trackable parcels and by company staff . At the laboratory, rock samples were prepared and
analyzed by standard methods. The sample preparation involved crushing 70% to less than 2 mm, riffle split off
250 g, pulverize split to better than 85% passing 75 microns. Samples were analyzed by method ME -MS61, a
four-acid digest performed on 0.25 g of the sample to quantitatively dissolve most geological materials. Analysis
is via ICP-MS. Gold was analyzed in rock and soils by ALS in Lima using a standard sample preparation and 30
g fire assay sample ch arge. Soil samples were analyzed by a portable XRF (VANTA -VMR) using an in -house
protocol which includes routine use of CRM and field duplicates as well as 10% check samples analyzed by ALS
Lima.
Channel samples are considered representative of the in -situ mineralization samples. At this stage true widths
of mineralization are not known. Grab or panel samples are selective by nature and are unlikely to represent
average grades on the property.
