NEWS RELEASE JULY 29, 2025
HANNAN DEMONSTRATES SYSTEMATIC EXPANSION OF PREVISTO GOLD FOOTPRINT
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 the Previsto project in Peru.
Key Points:
1. Systematic Footprint Expansion Across Multiple Directions The new channel results demonstrate
mineralization extending 30 m eastward (CH16811), 400 m south (CH16827), and 230 m southeast
(CH16836) from the previously announced central high-grade zone (69.1 m @ 2.4 g/t Au), systematically
expanding the known mineralized footprint and proving the extensive lateral continuity of the alkaline
epithermal system.
2. Extensive Mineralized Footprint Identified Across Large-Scale System These results validate the
presence of a broad, low to moderate-grade alkaline epithermal system with excellent structural continuity
across a very large 3 km x 3 km footprint, reinforcing the large areas of low grade with smaller
pockets of high grades, typical of major alkaline gold systems and moving beyond localized high-grade
targeting.
3. Consistent Alkaline System Signature Over Extended Area All areas display consistent alkaline gold
system characteristics including K-feldspar porphyry host rocks, roscoelite phyllic alteration, and elevated
vanadium signatures (0.2% to 0.4% by pXRF), confirming the systematic nature of mineralization across
the expanded 3 km x 3 km area.
4. The results demonstrate excellent lateral continuity with intersections from random outcrops defined
below thick vegetation ranging from 11.5 m to 27 m wide , enabling a strategic shift from grade- based
targeting to understanding the fundamental structural architecture controlling this extensive alkaline gold
system, indicating potential for systematic exploration across the large footprint.
5. Belen Drilling Update: H annan has completed three Vista Alegre drill holes (184.6 m, 256.8 m and 347.6
m deep) testing a 2.4 km geophysical anomaly, with final assays pending. Drilling commenced at Ricardo
Herrera targeting a 1,000 m x 250 m chargeability anomaly with outcropping porphyry copper -gold
mineralization and strong phyllic alteration.
Michael Hudson, CEO, states: "These latest results confirm we've systematically outlined a 3 km x 3 km
alkaline epithermal gold system with exceptional lateral continuity - the hallmark of a district- scale find. The
consistent gold -silver-tellurium mineralization, roscoelite alteration, elevated vanadium signatures, and K -
feldspar porphyry host rocks across this expanded footprint demonstrate we're dealing with a coherent
hydrothermal system, not isolated occurrences. This structural architecture and geochemical fingerprint mirrors
what we see at world-class alkaline systems like Cripple Creek, with similar high-grade pockets within a 'sea of
gold'. With environmental baseline work completed for Previsto drill permitting and our inaugural drilling program
at Belen delivering three completed holes awaiting assays, we're systematically advancing multiple high -grade
targets across this emerging 150 km mineral belt."
Technical Discussion
Previsto Central Gold Mineralization
As for global alkaline gold analogues like the Cripple Creek gold system in Colorado, Previsto demonstrates
remarkable parallels, particularly in grade distribution characteristics. At Cripple Creek, historic high -grade
telluride veins produced bonanza ores grading several hundred tr oy ounces per ton, with Bob Womack's initial
discovery yielding 10 to 12 troy ounces per ton and the famous "Cresson Vug" containing massive concentrations
of calaverite and sylvanite tellurides. While modern heap leach operations at Cripple Creek now process low -
grade material averaging 0.50 g/t Au, the Previsto system exhibits encouraging similarities to Cripple Creek's
original high-grade discovery phase.
Recent channel results at Previsto Central, including 69.1 m @ 2.4 g/t Au, 13 g/t Ag and 11 g/t Te (uncut),
with higher-grade intervals of 3.0 m @ 12.7 g/t Au, 49 g/t Ag, 43 g/t Te , 3.0 m @ 11.2 g/t Au, 53 g/t
Ag, 36 g/t Te and 0.7 m @ 16.1 g/t Au, 60 g/t Ag, 48 g/t Te, suggest Previsto may represent an alkaline
gold system in its early stages of exploration. Like Cripple Creek's historic high-grade zones that were structurally
controlled and persisted to depths exceeding 900 m, Previsto's roscoelite-altered zones with gold-silver-tellurium
mineralization and similar alkaline igneous host rocks indicate the potential for both high-grade structural zones
and extensive lower-grade disseminated mineralization that could support future exploration and development
scenarios.
Latest Results
The latest channel sampling results from Previsto Central ( Figures 3 and 4), collected from newly discovered
outcrops in heavily vegetated steep terrain, continue to demonstrate the extensive nature of the alkaline
epithermal gold system beyond previously defined high- grade zones. While this month's fieldwork returned
modest grades , the results significantly expand the mineralized footprint and reinforce the "sea of gold"
characteristics typical of large alkaline gold systems.
Channel CH16811 extends the known mineralization 30 m eastward beyond the currently defined gold zone,
intersecting 18 m @ 0.13 g/t Au and 2 g/t Ag, including a higher-grade interval of 3 m @ 0.59 g/t Au and
2 g/t Ag . The channel is hosted within K -feldspar porphyry (KFP) and breccia units, displaying low -intensity
roscoelite phyllic alteration with goethite-ilmenite assemblages. Portable XRF analysis reveals elevated titanium
(3.6%), lead (0.4%), and vanadium (0.2%) concentrations, consistent with the alkaline system signature.
Channel CH16827 represents the highest-grade intersection in this press release, returning 11.5 m @ 0.67
g/t Au and 6 g/t Ag, including 1.2 m @ 2.4 g/t Au and 6 g/t Ag. Located 400 m south of the central
high-grade zone but within the existing mineralized footprint, this channel intersect ed fluorite-adularia-
pyrite±chalcopyrite veinlets and stockwork zones within KFP host rock displaying moderate phyllic alteration.
The elevated vanadium signature (0.4% by pXRF) further supports the alkaline gold system model.
Channel CH16836 demonstrates excellent lateral continuity, intersecting 27 m @ 0.36 g/t Au and 4 g/t
Ag, including two distinct higher -grade intervals of 6 m @ 0.67 g/t Au and 6 g/t Ag and 3 m @ 0.54 g/t
Au and 3 g/t Ag. Positioned 230 m southeast of the high-grade zone, this intersection occurs within KFP
and hornfels units exhibiting phyllic alteration and quartz-adularia-goethite vein stockworks.
These results continue to validate the presence of a broad, low to moderate -grade alkaline epithermal system
with excellent structural continuity across a very large footprint (3 km x 3 km). K-feldspar porphyry remains the
dominant host lithology, with variable contributions from breccia and hornfels units. Ongoing field work focuses
on defining the primary structural controls governing mineralization distribution, moving beyond grade -based
targeting to understand the fundamental architecture of this extensive alkaline gold system.
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 three drill holes will test distinct sections of the 2.4 km long geophysical anomaly
targeting two zones. HDDVA001 was completed at 184.6 m, HDDVA002 has been completed at 256.8 m
and third hole HDDVA003 has been completed at 347.6 m. Final assays are awaited.
• Ricardo Herrera: The drill rig has now moved to 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 later al extent of
the mineralized system. HDDRH001 has commenced drilling on a combined geological, geochemical and
IP chargeability anomaly with a planned depth of 500 m.
• 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 the first part of August 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 includin g 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. Final DIA and other approvals are anticipated during Q3
2026.
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 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.
