Anzá restarts with strong set of drilling results.
Anzá restarts with strong set of drilling results.
• Assays from final three Pepas infill holes show strong results,
including:
o PEP072B - 47.60m @ 3.43g/t Au from surface
o PEP073 - 104.45m @ 5.96g/t Au from surface
o PEP074 - 71.35m @ 6.46g/t Au from surface
• Pepas drill database delivered to consultants, MRE modelling
underway.
• Planning underway for commencement of feasibility process.
• Drilling restarts at Anzá after Christmas break.
• Area under exploration licences ("Titles") increased by 65% as
two major mineral exploration applications converted to Titles -
exploration plans to be developed.
London, January 8th, 2026 . Orosur Mining Inc. ("Orosur" or the
"Company") (TSXV/AIM:OMI), is pleased to announce an update on the
progress of exploration activities at the Company's exploration project at
Anzá in Colombia ("Anzá).
Anzá - Colombia
The Anzá Project in Colombia comprises a number of granted exploration
titles and applications totalling roughly 327km 2 within the Mid -Cauca gold
belt, west of the city of Medellin.
These titles and applications are owned by two Colombian companies,
Minera Anzá, and Minera Monte Aguila, both of which are wholly owned
subsidiaries of the Company. The latter of these was acquired by Orosur in
November 2024 from the Company's previous JV partners, Newmont Mining
and Agnico Eagle Mines. Orosur thus owns 100% of the Anzá Project.
Since acquiring 100% control, the Company has focussed its attention on
three prospects:
• Pepas - a shallow, high-grade body of gold mineralisation that the
Company is endeavouring to move to an initial Mineral Resource
Estimate in the near term.
• APTA - a high-grade body of gold mineralisation that has to date seen
38,000m of drilling, but is not yet sufficiently understood geologically
to allow a MRE to be calculated. The Company plans to undertake
additional drilling at APTA in 2026, with the objective of advancing it
toward an MRE.
• El Cedro - a large gold porphyry system in the south of the Project
area. The Company has completed a large soil sampling program
and plans to undertake a maiden drill program here in early 2026.

Pepas Drilling
As announced on 14th July 2025, the Company had taken the formal decision
to commence infill drilling at its Pepas gold prospect at Anzá, with the
objective of moving Pepas to a NI43 -101 compliant Mineral Resource
Estimate ("MRE") as quickly as possible.
This infill drill program was completed late in December 2025, with results
from the final three holes PEP072, PEP073 and PEP074 just received.
As expected, gold assay results from these three holes were exceptional,
demonstrating the core of Pepas to contain very thick, high -grade zones of
gold mineralisation.

With the receipt of these results, the gold assay database has been closed
off and handed to our resource consultants so that work on the MRE
modelling process can commence.
Feasibility
The Company has begun the process of assessing the economic exploitation
options for Pepas in the context of the Colombian permitting regime.
Discussions are currently underway with local technical consultants to map
out the permitting framework, necessary environmental and social studies,
and development of the required technical work plan (Programa de Trabajo
y Obras - PTO), that could commence once an MRE is finalised.
Wider Exploration
Following the Christmas break and retirement of the old drill rig for much
needed repairs, a new rig has arrived on site to commence a regional drill
program north of Pepas. This program is reconnaissance in nature, designed
to better understand the wider litho-structural environment that controls the
Pepas mineralisation.
As has been previously announced, plans for drilling programs to the south
at APTA and El Cedro will be progressed once airborne geophysical surveys
have been undertaken over these prospects. Options for this work are being
assessed.
Granting of mining exploration licences ("Titles")
The Company is constantly assessing its land package in Colombia in terms
of geological potential, costs to hold, the ability of exploration work to be
undertaken and any subsequent discovery exploited in light of local
community sentiment.
To that end, several major adjustments were made at the end of December
2025.
Two of the larger, longer held applications, that made up the bulk of the
original Anzá JV project, have now been granted, and converted to
exploration licences (Figure 1). The Company thus now has three large
contiguous granted Titles, totalling 173km2, a ll within the mining friendly
Anzá municipality, an increase of some 65%.
Reconnaissance surface work has previously been undertaken on these new
licences by the Company's previous JV partners. These data will now be re-
assessed and exploration plans developed accordingly now that drilling is
able to be undertaken.
In addition, several smaller applications have been dropped for various
reasons, including geological prospectivity, or likely inability to able to be
explored as they fall outside Anzá municipality in less receptive areas.
The Company thus currently now has 154km2 under application.
Orosur CEO Brad George commented:
"The Company starts 2026 in a very different position to a year ago. One
deposit (hopefully) soon to enter feasibility, two rigs turning in two countries
and an increasing list of high -quality targets lining up to be next. Exciting
times".

About Orosur Mining Inc.
Orosur Mining Inc. (TSXV: OMI; AIM: OMI) is a minerals explorer and developer currently operating in Colombia
and Argentina.
Qualified Persons Statement
The information in this news release was compiled, reviewed, verified and approved by Mr. Brad George, BSc
Hons (Geology and Geophysics), MBA, Member of the Australian Institute of Geoscientists (MAIG), CEO of Orosur
Mining Inc. and a qualified person as defined by National Instrument 43-101.
Orosur Mining Inc. staff follow standard operating and quality assurance procedures to ensure that sampling
techniques and sample results meet international reporting standards.
Drill core is split in half over widths that vary between 0.3m and 2m, depending upon the geological domain. One
half is kept on site in the Minera Anzá core storage facility in the case of the Anza Project, or on site in temporary
racks in the case of the El Pantano Project, with the other sent for assay.
Industry standard QAQC protocols are put in place with approximately 10% of total submitted samples being
blanks, repeats or Certified Reference Materials (CRMs).
Samples for holes PEP-001 to PEP-011 were sent to the Medellin preparation facility of ALS Colombia Ltd, and
then to the ISO 9001 certified ALS Chemex laboratory in Lima, Peru.
Samples from PEP-012 onwards are sent to Medellin laboratory of Actlabs for preparation and fire assay, with
some sample then sent to the Canadian Actlabs facility for multi element assay
Samples from the EL Pantano project are sent to the preparation facility and fire assay laboratory of Alex Stewart
Laboratories in Perito Moreno to be assayed for gold. Pulps are then sent to the larger Alex Stewart facility in
Mendoza for multi-element analysis.
30 gram nominal weight samples are then subject to fire assay and AAS analysis for gold with gravimetric re-
finish for overlimit assays of >5 g/t. ICP-MS Ultra-Trace level multi-element four-acid digest analyses may also
undertaken for such elements as silver, copper, lead and zinc, etc.
Gold intersections are reported using a lower cut-off of 0.3g/t Au over 3m.
Intersections are quoted as downhole thicknesses. True thicknesses are unknown.
