AUMEGA METALS COMMENCES INAUGURAL DRILLING OF THE ISLE AUX MORTS GRANITE

Aumega Metals Ltd. has commenced diamond drilling as part of the company's 2026 exploration program at the Isle aux Morts granite (IAMG) and Cape Ray West along the Cape Ray shear zone (CRSZ) in Newfoundland and Labrador, Canada.

The initial phase of drilling will focus on priority targets associated with the IAMG and the adjoining Cape Ray West area, neither of which have previously been drilled. The program is designed to test a series of structural, geochemical and geophysical targets identified through the company's systematic regional exploration program and recent geological interpretation.

Highlights:

• Diamond drilling has commenced at the IAMG, marking the start of Aumega's planned 2026 exploration drilling program.
• The IAMG and adjoining Cape Ray West targets have never been drilled, offering first-ever tests of priority structures along the CRSZ and into the IAMG.
• Targets were defined by integrating geological mapping, surface geochemistry, geophysics and structural interpretation across a comparatively underexplored portion of the company's extensive land package.
• Drilling program expected to move to Bunker Hill upon completion of IAMG and Cape Ray West drilling later in the summer of 2026.

The Isle aux Morts granite represents a prominent geological feature within the western portion of the company's property. Exploration completed by Aumega has identified a number of prospective structural corridors and geochemical gold anomalies along and adjacent to the granite contact. These areas have received limited historical exploration and represent an opportunity to test new geological concepts within a district that hosts multiple known gold deposits and mineralized trends.

At Cape Ray West, drilling will target interpreted structures located several kilometres southwest of the company's existing mineral resources. The area is considered prospective due to its structural position within the broader CRSZ and the presence of supporting geological, geochemical and geophysical indicators. The initial holes are intended to establish the subsurface geology, test the interpreted structures, and assess whether alteration and mineralization are present.

Following this initial drilling at IAMG and Cape Ray West and while awaiting assay results from this drill program, the company expects to commence drilling at Bunker Hill later in the summer.

Sam Pazuki, managing director and chief executive officer of Aumega, commented: "The commencement of drilling is an important milestone for our 2026 exploration program. The Isle aux Morts granite and Cape Ray West areas have emerged as priority targets following the integration of several seasons of geological, geochemical and geophysical work. This comes as we spent much of the past two years building a pipeline of drill targets.

"These are early-stage targets, but they are supported by a clear geological rationale and are located within a highly prospective structural setting. The objective of this initial drilling is to test the underlying geological concepts, improve our understanding of the area and determine whether these target corridors warrant more extensive follow-up.

"Aumega controls a large and underexplored land position along the Cape Ray shear zone. This program is another step in systematically evaluating that broader opportunity while maintaining a disciplined and evidence-based approach to exploration. It's an important step toward our clear objective of making the next major discovery in Newfoundland."

About Aumega Metals Ltd.

Aumega Metals is utilizing best-in-class exploration to explore on its district-scale land package that spans 110 kilometres along the Cape Ray-Valentine shear zone, a significant underexplored geological feature recognized as the largest identified gold structure in Newfoundland, Canada. This zone currently hosts Equinox Gold's Valentine gold project, a multimillion-ounce deposit, which is the region's largest gold project, along with Aumega's mineral resource. Additionally, Aumega holds a 27-kilometre stretch of the highly prospective Hermitage flexure.

The company is supported by a diverse shareholder registry of prominent global institutional investors including Condire Investors LLC and strategic investment from B2Gold Corp., a significant, intermediate gold producer.

Aumega's Cape Ray shear zone hosts several dozen high-potential targets, along with its existing defined gold mineral resource of 6.2 million tonnes grading an average of 2.25 grams per tonne gold, totalling 450,000 ounces of indicated resources, and 3.4 million tonnes grading an average of 1.44 grams per tonne gold, totalling 160,000 ounces in inferred resources.

Aumega acknowledges the financial support of the junior exploration assistance program of the Department of Industry, Energy and Technology of the provincial government of Newfoundland and Labrador, Canada.
