HANNAN EXPANDS PREVISTO ALKALIC GOLD FOOTPRINT TO 750 METRES STRIKE
TRENCHES INCLUDE 4.6 m @ 7.2 g/t GOLD IN 30 METRE STEP OUT
Vancouver, Canada -- Hannan Metals Limited's ("Hannan" or the "Company") (TSXV: HAN) (OTCPK:
HANNF) is pleased to report new high -grade gold assay results from its 100% owned alkalic epithermal gold
target at Previsto project in Peru.
Four Key Points:
1. Two new perpendicular high-grade channels at Previsto assayed:
• 13.6 m @ 2.1 g/t Au and 17 g/t Ag (CH16348) (Figures 3 and 4)
• 4.6 m @ 7.2 g/t Au and 26 g/t Ag (CH16468) (Figures 3 and 4)
• Both located up to 30 m east of previous high-grade gold channel sampling. The channels remain
open in all directions.
2. New outcropping high grade zone emerging: A panel sample covering 1 m² from an outcrop in central
Previsto Central, located 255 m SSW from the samples over, assayed 2.2 g/t Au, 11 g/t Ag and 0.13% Cu
(Figures 3 and 4).
3. Expanded footprint: The new strongly altered gold anomalous outcrop discovery has expanded Previsto
Central 100 m southwards now covering 750 m of strike (Figure 3 and 4).
4. Declaracion de Impacto Ambiental ("DIA") or Environmental Impact Statement work to approve
drilling commences at Previsto.
Michael Hudson, CEO, states: "These latest results from Previsto Central continue to demonstrate the
exceptional potential of our Previsto alkalic epithermal gold system. The ability of our team to consistently follow
up high-grade gold mineralization in outcrop across new areas, including 4.6 m @ 7.2 g/t Au , located 30 m
from previous sampling, is particularly impressive. Combined with the continued expansion of our mineralized
footprint to 750 m of strike length within our broader 4 km by 4 km soil gold anomaly, these results reinforce
our growing confidence in this emerging globally significant alkaline gold target.
"What's particularly exciting is our discovery of new outcropping high-grade zones, including a 2.2 g/t Au panel
sample located 255 m SSW of our known high -grade area. With only a small percentage of the prospective
ground investigated to date, the potential to identify additional high-grade zones along our current 750 m strike
length remains very strong.
"The new gold rich areas found at Previsto, combined with our ongoing drilling program at Belen located 22 km
SSW, where we've completed two drill holes and are advancing a third, demonstrate that Hannan is
systematically proving up multiple district- scale targets across the Valiente mineral belt. These new results
position us strongly as we also advance drill permitting at Previsto, with our Environmental Impact Statement
(DIA) work now underway and final submission to relevant government agencies anticipated during 2025."
Technical Discussion
Previsto Central Gold Mineralization
As for global alkaline gold analogues like Cripple Creek, Previsto continues to demonstrate higher-grade gold
where structural focusing has occurred within a larger and extensive envelope of lower grade mineralization,
suggesting that the alkaline fluids had sufficient gold-carrying capacity to create both high-grade focused areas
and large-tonnage, lower-grade areas. The Previsto Central zone represents the core high-grade area within the
broader Previsto Central alkalic epithermal gold system.
1. Latest High-Grade Channel Results
Two new perpendicular high- grade channels at Previsto Central (Figures 3 and 4) , located up to 30 m east of
previous Hannan channel sampling reported on February 06, 2025 and April 07, 2025 (which returned 135.2 m
@ 1.3 g/t Au including 26.0 m @ 5.4 g/t Au and 27 g/t Ag) have returned exceptional results that remain open
at each end:
• 4.6 m @ 7.2 g/t Au and 26 g/t Ag (CH16468) - demonstrating the high-grade potential within the
broader mineralized envelope and confirming the continued presence of high-grade areas
o Including 3.4 m @ 9.6 g/t Au. 34 g/t Ag and 30 g/t Te
• 13.6 m @ 2.1 g/t Au and 17 g/t Ag (CH16348 ) - representing a broad zone of consistent gold
mineralization demonstrating excellent continuity within the system
o Including 0.3 m @ 13.3 g/t Au, 24 g/t Ag, 34 g/t Te
2. New High-Grade Surface Outcrop Zone
A significant new zone 255 m south of the high -grade results above in (1) includes a 1 m² panel sample from
an outcrop in central Previsto Central, located 255 m SSW from the high -grade channels, which assayed 2.2
g/t Au, 11 g/t Ag and 0.13% Cu. This represents an important find of outcropping high er-grade
mineralization (Figures 3 and 4).
3. Expanded Footprint
A strongly altered gold anomalous outcrop zone extending the system 100 m southward, bringing the total strike
length to 750 m within a zone up to 100 m wide . Four panel and chip samples reported here returned an
average of 0.2 g/t Au and 2 g/t Ag, with results ranging from a maximum of 0.4 g/t Au and 2 g/t Ag and a
minimum of 0.2 g/t Au and 2 g/t Ag (Figures 3 and 4).
System Characteristics and Mineralization Style
Gold mineralization at Previsto Central displays the characteristic features of alkalic -type epithermal systems,
hosted within brecciated, calcareous K-feldspar porphyry of syenitic protolith. The mineralization exhibits several
key characteristics:
1. High-grade gold zones are associated with pervasive fine roscoelite (vanadium -rich potassic mica)
and fine grey quartz veining with pyrite, occurring as both veinlets and stockwork textures.
2. Alteration assemblages include manganese oxides replacing vein and breccia fill, suggesting that
unweathered mineralization contained rhodochrosite, a manganese carbonate mineral typically found in
low-sulfidation epithermal systems.
3. Primary mineralization consists of 1% disseminated pyrite with trace chalcopyrite, pyrite veinlets,
roscoelite veinlets, and fine jarosite veinlets (likely after pyrite).
4. Structural controls suggest gold deposition was focused along late strike- slip faults where horizontal
movement created extensional structures within a compressional regime.
Drilling Program at Belen
Belen is located 23 km SW of Previsto Central. The initial phase of drilling at Belen zone consists of up to 5,000
m across 18 diamond drill holes designed to test the three primary target areas at Belen:
• Vista Alegre: The first drill holes will test distinct sections of the 2.4 km long geophysical anomaly
targeting two zones . HDDVA001 was completed at 184.6 m and HDDVA002 has been completed at
256.8 metres. A third hole HDDVA003 with a target depth of 300 m is now underway. All holes target a
600 m long and 500 m deep high chargeability- low resistivity zone coinciding with strong gold -in-soil
anomaly (up to 0.12 g/t Au) and gold mineralization in boulders correlating with Au-Ag-Te-As (up to 2.72
g/t Au and 44 g/t Ag).
• Ricardo Herrera: The next set of planned drill holes will target the core of the substantial chargeability
anomaly that extends over 1,000 m by 250 m with outcropping porphyry-style copper-gold mineralization
showing moderate to strong phyllic alteration, with drill pads positioned strategically to test the lateral
extent of the mineralized system.
• Sortilegio: The final phase drilling will investigate the 1.2 km long chargeability anomaly within the alkalic
porphyry system. Drillholes will target the source of extensive surface soil copper anomalies coinciding
with hydrothermal gold anomalous quartz -gossan boulders with elevated Au -Mo-Te. The chargeability
response consists of three alkalic Cu-Au targets identified within the 1.2 km long trend.
The drilling program is expected to take approximately 6 months to complete, with first assay results anticipated
in July 2025.
Hannan Metals is committed to legal compliance, community respect, and environmental stewardship,
emphasizing that all operations only proceed with proper authorization from local populations and with required
environmental and archaeological certifications.
Drill Permitting in Previsto
A ten-person environmental team including professional environmental archaeological investigations, community
workshops and liaison activities has commenced 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;
• 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. Final DIA and other approvals are anticipated during Q3
2026.
Drilling Program at Cerro Rolando, Chile
The Company completed one hole at Cerro Rolando to test an electromagnetic ("EM") conductor modelled
between 60 m to 100 m depth beneath the pampa sands and gravels. A low -cost reverse circulation drill hole
test was completed at 116.0 m to test the target. The EM anomaly was found to be caused by evaporitic horizons
between 70 m to 88 m and 98 m to 110 m, satisfactorily explaining the EM. Given the absence of a mineralized
supergene copper blanket, the option over the Cerro Rolando property has been terminated, while the Company
continues to focus on its highly prospective Peruvian projects.
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
250g, pulverize split to better than 85% passing 75 microns. Samples were analyzed by method ME- MS61, a
four-acid digest performed on 0.25g 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 30g
fire assay sample charge. 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.
