Orosur Mining Inc Announces Pepas Drilling

In This Article:

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 now 100% owned by the Company following recent completion of a Share Purchase Agreement (SPA), announced 28th 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).

The Company began drilling at the Pepas prospect in mid-November 2024, just prior to completion of the MMA purchase transaction.

Drilling commenced with hole PEP012, which was positioned to confirm previous high-grade results in hole PEP001, PEP005 and PEP007, drilled by MMA in 2022.

Holes PEP013, PEP014 and PEP015 were then rotated some 51 degrees Eastward from PEP012 to begin to test what was considered by Company geological teams to the controlling trend of SE to NW. As well as defining thick zones of high-grade mineralisation, a target for these holes was a clearly defined basement fault that seemed to act as a distinct marker bed to define the trend.

Figure 2. Plan of holes

Holes PEP013 and PEP014 both intersected the basement fault at roughly the depth predicted, and both recorded substantial intersections of high-grade gold mineralisation above the basement fault.

Hole PEP015 was collared roughly 45m to the NW of PEP014, with the same azimuth and same objective.

From surface, hole PEP015 entered a thick zone of soils, saprolite, intense weathering and faulting, that appears substantially thicker and more complex than previous holes. The hole then entered the expected mineralised zone at a downhole depth of 23.5m, until the basement fault at 63.7m.

In this zone, a composite intersection of 40.2m @ 3.75g/t Au was recorded.

Discussion and ongoing drilling
At this early stage, it would seem that the NW end of current mineralised zone is more structurally complex and slightly lower grade than the SE end, with the gold grades encountered in PEP015 being similar to that intersected by the initial drilling in 2022 in holes PEP001, PEP005 and PEP007.
