RNS Number : 0672O  Orosur Mining Inc  08 January 2026

 

 

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 14(th) 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, all 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".

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

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.
