London, January 13th, 2025. 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 flagship Anzá Project (“Project”) in Colombia.
ANZÁ Project
The Anzá Project is 100% owned by the Company following recent completion of a
Share Purchase Agreement (SPA), announced 28 th November 2024, whereby the
Company purchased all of the shares of its previous JV partner, Minera Monte Aguila
(MMA).
The Project is located 50km west of Medellin and is easily accessible by all -weather
roads and boasts excellent infrastructure including water, power, communications as
well as a large exploration camp.
Pepas
The Pepas Prospect is in the northern extent of the Anzá Project (pre-acquisition) over
10km north of the central base at APTA (Figure 1).
Figure 1. Anzá Project – prospects
Pepas was discovered by MMA in late 2021 by BLEG sampling and geological
mapping, followed by 11 diamond drill holes in 2022 (PEP001 to PEP011).
On completion of the transaction to buy MMA, the Company restarted drilling at the
Pepas prospect in mid-November 2024.
Drilling commenced with hole PEP012, which was positioned to confirm previous
high-grade results in holes PEP001, PEP005 and PEP007 drilled by MMA in 2022.
Later holes (PEP013 to PEP015) were then rotated some 51 degrees clockwise from
PEP012 to begin to test what was considered by Company geological teams to be
the controlling trend of SE to NW. The primary objective of the first phase of drilling
by the Company was to attempt to understand the geological controls upon
mineralisation first identified in 2022, so as to provide guidance for later step out
drilling.
Holes PEP012 to PEP015 (previously announced) all intersected thick sequences of
high-grade gold mineralisation (table 2), and importantly, intersected a well-defined
basement fault that could be correlated from hole to hole and thus provide clear
guidance as to orientation.
Figure 2. Plan of holes
Holes PEP016 and PEP017 were both drilled downdip of previous holes, but at
opposing ends of the current mineralised zone , in order to test additional structural
complexities that were anticipated to the SW and to begin creating several drill
sections to aid in interpretation. PEP018 was then drilled up dip of and on section with
holes PEP013 and PEP017.
Both PEP016 and PEP017 intersected loose and broken ground from surface, likely
as a result of both holes being drilled through and sub -parallel to a large fault zone
running parallel to the known basement fault and converging at depth. Drilling within
this zone was difficult, with poor recoveries, such that PEP017 was aban doned, and
redrilled as PEP017B from the same pad, with slightly shallowe r dip so as to exit the
fault zone earlier.
Some evidence of the existence of this fault had been noted in surface mapping and
these holes were designed to test its location and nature to gain a better understanding
of the mineralisation.
Once leaving the fault zone, both holes entered the mineralised zone and recorded
substantial intersections of gold mineralisation.
PEP018 was drilled immediately up dip of PEP013 to extend the exceptional results
recorded in this previous hole. PEP018 entered high grade mineralisation from
surface, which continued until intersection of the expected basement fault.
Drill intersections for these three holes are as follows:
Hole Number From (m) To (m) Interval (m) Au (g/t)
PEP016 61.6 105.3 43.7 3.13
including 61.6 76.25 14.65 8.09
PEP017 56.1 96.3 40.2 2.06
including 56.1 64.15 8.05 4.42
including 74.35 78.6 4.25 8.3
PEP018 0 54.1 54.1 6.01
including 5.4 29.15 23.75 9.07

Discussion and ongoing drilling
Holes PEP016 , PEP017, and PEP018 are adding to the geological picture in the
centre of the Pepas zone.
The holes drilled since the Company took control of the Project less than six weeks
ago, have confirmed the Company’s assertion that previous drilling in 2022, while
successful in discovering Pepas , did not resolve the orientation of the mineralisation
as most holes were drilled sub -parallel to what is now thought to be the primary
orientation.
Holes PEP016 and PEP017 were drilled with the joint objectives of increasing the
understanding of the litho-structural framework of the deposit, with specific focus on a
fault that was expected in the SW of the area. A geological picture is beginning to
emerge of the current body of mineralisation sitting within the keel of two roughly
parallel faults that converge at depth with a southerly plunge.
Hole PEP018 was drilled up dip of hole PEP013 to complete a drill section. It was
expected to return an exceptional result and did not disappoint.
Hole PEP019 is located parallel to PEP018, some 30m along strike to the SE (figure
2), to gradually step out this mineralisation to the SE and to commence a new section.
This hole is currently underway.
Preliminary interpretation suggests these two major faults are likely to post -date
mineralisation. Attention is thus being given to examining the sense of movement of
these structures and their potential impact in offsetting mineralisation. Recent surface
mapping and geochemistry results are beginning to demonstrate substantial potential
northward of the current body and geological teams are currently expanding this work
with a view to developing new targets in addition to the definition drill program currently
underway at Pepas.
Since Orosur reassumed ownership and control of the Anzá project in late November
2024, seven holes have been drilled at the Pepas prospect , with all seven returning
outstanding gold intersections:
Hole Number From (m) To (m) Interval (m) Au (g/t)
PEP012 0 66.75 66.75 5.64
PEP013 0 77.30 77.30 7.68
PEP014 0 75.1 75.1 5.58
PEP015 23.5 63.7 40.2 3.75
PEP016 61.6 105.3 43.7 3.13
PEP017 56.1 96.3 40.2 2.06
PEP018 0 54.1 54.1 6.01

Orosur CEO Brad George commented:
“Drilling at Pepas continues to develop an exciting story. It has been less tha n six
weeks and yet we have achieved a huge amount, with seven holes drilled, all of which
have returned exceptional intersections. We will continue expanding Pepas, but
attention now also turns northward where tantalising surface mapping is attracting our
attention.”

Qualified Persons Statement
The information in this news release was compiled, reviewed and verified 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, 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 assay.
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.
