METALSOURCE MINING EXTENDS STRIKE LENGTH OF MINERALIZATION AT SILVER HILL WITH 65M SOUTH STEP OUT FROM SH26-19

Drill hole SH26-27 has intersected approximately 15 metres (core length) of polymetallic mineralization, extending the known Silver Hill system approximately 65 metres south of hole SH26-19 and representing the southernmost drill intercept reported by Metalsource Mining Inc. to date. The target horizon comprises approximately 15 metres of widespread sphalerite and galena dominant polymetallic mineralization, including an internal interval of approximately 3.5 metres of semi-massive to massive sulphides. The style and intensity of sulphide mineralization observed in SH26-27 are consistent with mineralization intersected elsewhere within the Silver Hill system. Laboratory assays remain pending.

Joe Cullen, chief executive officer of Metalsource Mining, commented:

"SH26-27 is another encouraging step forward for the program. While we'll allow the laboratory assays to speak for the grade, we're very encouraged by the style, thickness and continuity of the sulphide mineralization observed in the core. Importantly, this hole extends the known mineralized corridor approximately 65 metres south of SH26-19 and continues to demonstrate that the system remains open for expansion.

"Our focus now is twofold. While we look forward to receiving and reporting the assays from SH26-27 and the remaining pending holes as quickly as they become available, we're simultaneously accelerating the next phase of drilling around the exceptional mineralization intersected in hole SH26-07. As our second drill rig prepares to mobilize and begin testing newly identified district scale targets generated through our recent IP survey, we're continuing to build momentum on multiple fronts. We believe each phase of drilling is strengthening our understanding of the system and positioning Silver Hill for continued growth."

Multiple assays pending

Laboratory assays remain outstanding for SH26-27 and several additional drill holes completed as part of the company's continuing exploration program. A number of samples exceeded initial analytical thresholds and required overlimit reassay procedures to ensure accurate reporting. Metalsource will continue releasing assay results as they are received from the laboratory, providing a steady flow of technical updates as drilling advances across the Silver Hill project.

What is next:

• Release pending assays: Laboratory results remain outstanding for completed drill holes and will be released as they become available.
• Highest-grade corridor: The next phase of drilling will focus on expanding the exceptional polymetallic mineralization surrounding hole SH26-07 through systematic drilling along strike, downplunge and at depth.
• Accelerating exploration: Mobilization of the company's second drill rig remains on schedule, allowing Metalsource to simultaneously expand the known Silver Hill system while testing newly identified high-priority IP targets across the broader district.
• Building toward a maiden resource: Continuing drilling continues to improve geological understanding and expand the known mineralized footprint in support of an inaugural mineral resource estimate currently targeted for early 2027.
• Evaluating strategic land expansion: Metalsource is assessing opportunities to expand its land position in prospective areas identified through geological and geophysical analysis, strengthening its ability to explore district-scale potential.

Why this matters to investors

SH26-27 represents another important milestone in Metalsource's systematic expansion of the Silver Hill polymetallic system. While laboratory assays remain pending, the hole marks the company's largest southern step out to date, extending the known mineralized corridor approximately 65 metres beyond hole SH26-19, and continuing to demonstrate that mineralization remains open to the south, at depth and along the broader trend. The visual continuity of sulphide mineralization provides further confidence in the company's evolving geological model as exploration advances beyond the historic mine footprint.

The visual presence of widespread sphalerite and galena is significant because these are the principal sulphide minerals associated with Silver Hill's polymetallic mineralization, further strengthening confidence that drilling continues to intersect the same expanding mineralized system.

Importantly, SH26-27 is not the conclusion of this phase of exploration, but another step in a broader strategy. As assays continue to be released, Metalsource is simultaneously advancing the next phase of drilling around the exceptional mineralization intersected in hole SH26-07 while preparing to mobilize a second drill rig to begin testing newly identified district scale targets generated through the company's recent IP survey. This dual-track approach is designed to accelerate both resource growth and discovery potential as the company continues unlocking the broader Silver Hill district.

Metalsource QA/QC (quality assurance/quality control) protocols are maintained through the insertion of certified reference material (standards), blanks and duplicates within the sample stream. The drill core is cut in half with a diamond saw, with one-half placed in sealed bags and shipped to the laboratory and the other half retained on site. Chain of custody is maintained from the drill to the submittal into the laboratory preparation facility.

Analytical testing is performed by ALS Geochemistry (Reno, Nev.) and ALS Canada (Vancouver, B.C). The entire sample is crushed to 70 per cent passing a two-millimetre mesh, with a 250-gram (g) split pulverized to 85 per cent passing minus 75 microns. A four-acid digest is performed on 0.25 g of sample to quantitatively dissolve most geological materials. Analysis is performed with a combination of ICP-AES (inductively coupled plasma atomic emission spectroscopy) and ICP-MS (inductively coupled plasma mass spectrometry) and fire assay.

The exploration results described herein are preliminary in nature and are insufficient to define a mineral resource. Further drilling is required to determine the continuity, geometry and grade distribution of mineralization. At the time of this news release, analytical results remain pending.

Metal values used in AgEq (silver equivalent) calculations are from the 200-day moving average values from Feb. 6, 2026, and all values are in U.S. dollars. P Au (gold) equals $124.5 per g P Ag (silver) equals $1.58 per g, P Cu (copper) equals $4.9 per lb, P Pb (lead) equals 90 cents per pound (lb), P Zn (zinc) equals $1.11 per lb, 0.00220462262 equals gram-to-pound conversion factor, 22.0462262 equal pounds per tonne for 1 per cent metal. Metal recoveries used in the AgEq calculation are: Au -- 95.5 per cent; Ag -- 92.9 per cent; Pb -- 89.2 per cent; Zn -- 93.8 per cent; and Cu -- 90.8 per cent. These recovery values are derived from batch metallurgical testing used to estimate recoveries of Silver Hill ores, completed in 1988. Individual metal values in the results table are composited values and not factored by recovery. Metal recoveries are applied to their respective component of the AgEq calculation only.

Silver Hill project

Located in the Carolina terrane, the property is underlain by volcaniclastic and volcano sedimentary rocks predominantly of Neoproterozoic and Cambrian age. Current interpretations suggest this terrane is an extension of the Avalon terrane. The property is 1,225 acres located in Davidson county, North Carolina. As the first significant discovery and first silver-producing mine in America, the property is supported by an extensive historic data set, including drill hole data, underground mapping, historical dumps and underground chip samples. Currently known mineralization extends to 550 metres from surface, in a steeply trending series of lenses, which remain open in multiple directions.

Byrd-Pilot Mountain project

The Byrd-Pilot Mountain project is located in central North Carolina within the Carolina terrane. Initial USGS (U.S. Geological Survey) surveys in the 1980s identified the area as a potential host for a porphyry gold-copper system. Subsequent exploration demonstrated broad gold mineralization in soils, trenches and shallow RC (reverse circulation) drilling, coincident with strong self-potential anomalies. Geology shows intense quartz-sericite-pyrite alteration, high-sulphidation signatures and high-alumina minerals (like Haile and Brewer deposits to the south), suggesting potential for a large epithermal or porphyry-related gold system. Geologic modelling of currently identified mineralization indicates an east-west trend open in multiple directions, with oxidation noted down to a depth of 30 metres. No drilling has tested the Meridian discovery zone since those 1980s campaigns, leaving potential for significant resource expansion through work commitments of the agreement.
