NEW AGE METALS REPORTS UP TO 51.9% ANTIMONY AND 46.2 G/T GOLD FROM PHASE 2 EXPLORATION AT ST. ALBAN’S, NEWFOUNDLAND

February 27, 2026 – Rockport, Ontario– New Age Metals Inc. (TSX.V: NAM | OTCQB: NMTLF | FSE: P7J) (“NAM” or the “Company”) is pleased to report results from its Phase 2 follow-up exploration program at the Company’s St. Alban’s antimony–gold properties in southern Newfoundland and Labrador.

Phase 2 exploration returned high-grade results, including assays of up to 51.9% antimony (Sb) [Figure 1] and 46.2 g/t gold (Au) [Figure 2], significantly strengthening the structurally controlled Au–Sb mineralizing system first identified during Phase 1 exploration (see August 27, 2025 news release).

Phase 2 Highlights

In addition, we have expanded our land position to include the Pardy Head occurrence, secured trenching approvals, and completed additional late season work up until the snow prohibited work in December. This was all done while leveraging provincial support through the Junior Exploration Assistance program. With

further assays pending, our technical team continues to develop a stronger understanding of the structural controls of mineralization. We believe that the project is well positioned for drilling next season.”

Regional Context – Emerging Au-Sb Corridor

Phase 2 results further confirm structurally controlled Au–Sb mineralization hosted within quartz veins of the St. Joseph’s Cove Formation.

Mineralization extends along a regional structural trend from Swanger’s Cove, through Antimony Ridge (MODS# 001M/13/Sb 002) and Golden Grit (MODS# 001M/13/Au 015), to the True Grit (MODS# 001M/13/Au 014) occurrence.

This continuity supports district-scale potential along an emerging Au–Sb corridor in the St. Alban’s area. Ongoing work is progressively defining discrete structural zones within this broader trend, allowing the Company to narrow exploration toward specific target areas.

Antimony Ridge – Phase 2 Results

Phase 2 work has defined three distinct mineralized zones within the Antimony Ridge property.

Central High-Grade Gold Zone

The strongest gold mineralization identified to date during Phase 2 occurs within a central structural zone. Grab samples returned:

• 46.2 g/t Au (Sample 214444)
• 23.8 g/t Au (Sample 445126)
• 8.21 g/t Au (Sample 445116)
• 7.16 g/t Au & 2.51% Sb (Sample 445132)

Gold mineralization is hosted within narrow quartz veins that cross-cut the regional foliation and are spatially associated with NNW–SSE-trending fault structures interpreted to represent later brittle deformation.

In contrast, antimony-bearing quartz veining identified elsewhere on the property appears largely foliation-parallel, suggesting that gold mineralization may represent a structurally overprinting event focused along cross-cutting fault zones.

The relationship between foliation-parallel Sb veining and cross-cutting Au-bearing structures highlights the potential for enhanced mineralization at structural intersections, providing clear vectors for continued trenching and drill targeting.

Northwestern Stibnite-Bearing Structural Corridor

The northwestern portion of the property hosts a well-defined structural corridor where the technical team traced multiple parallel to sheeted quartz veins, approximately 10–30 cm wide, exposed in outcrop over approximately 400 metres of strike length.

These quartz veins are oriented sub-parallel to the regional foliation, indicating that antimony mineralization is largely foliation-controlled and developed within a ductile structural fabric of the host rocks.

Sampling from these foliation-parallel sheeted quartz veins returned antimony values up to 6.57% Sb, confirming stibnite-bearing mineralization within a structurally continuous bedrock corridor. The continuity and geometry of this mineralized vein system define a coherent surface target for drill testing.

Southeastern High-Grade Antimony Zone

The southeastern portion of the property hosts the highest-grade antimony values identified to date, including over-limit samples grading:

• 51.9% Sb (Sample 445127)
• 51.2% Sb (Sample 445128)

Associated gold values include 6.53 g/t Au, 6.42 g/t Au, and a cluster of 4–5 g/t Au results.

The abundance and angular nature of mineralized float, combined with coincident soil anomalies, suggests a proximal bedrock source that has not yet been exposed. This southeastern zone represents a high-priority trenching target for the 2026 field season.

Polymetallic Character of the System

In addition to high-grade gold and antimony, Phase 2 sampling confirmed elevated base- and preciousmetal values across multiple properties within the St. Alban’s project area.

Quartz-vein sampling at Antimony Ridge returned up to:

• 39,215 ppm Zn
• 3,672 ppm Pb
• 2,927 ppm Cu

On the Fort Property, Phase 2 sampling returned strongly anomalous lead values, including assays up to 21,937 ppm Pb, confirming that base-metal mineralization occurs beyond the Antimony Ridge corridor.

Notably, Phase 1 exploration at the Fort Property returned even higher-grade lead and high-grade silver values (see August 27, 2025 news release), demonstrating continuity of polymetallic mineralization within the broader structural trend.

Elevated Zn, Pb, Cu, Ag, and As values identified during both Phase 1 and Phase 2 programs highlight the presence of a robust polymetallic hydrothermal system active along the regional Au–Sb corridor. The widespread and consistent distribution of this multi-element signature across multiple properties supports the interpretation of a district-scale, structurally controlled mineralizing system.

Land Consolidation – Pardy Head

The Company staked an additional 40 mineral claims (~1,000 hectares), further consolidating the mineralized trend and capturing the Pardy Head antimony occurrence where government mapping confirms stibnite-bearing quartz veins in outcrop.

Notes: n.d. = not determined.

Cautionary Note: Grab rock (outcrop and boulder) samples are selective by nature and are unlikely to represent average grades on the Property. These results are preliminary in nature and not conclusive evidence of the likelihood of the occurrence of a mineral deposit. However, these samples demonstrate significant antimony and gold (and copper, zinc, silver and lead) mineralization potential on portions of the St. Alban’s area properties.

Analytical Methods, Chain of Custody, and Quality Assurance/Quality Control

NAM maintains a rigorous QA/QC protocol for all rock samples collected during the Phase 2 program. Field crews inserted certified reference materials (“CRMs”) and analytical blanks at a rate of approximately one QA/QC sample for every 20 primary samples, ensuring that ~5% of all submitted samples were independent quality control checks. The CRMs were sourced from industry-certified providers and selected to match, as closely as possible, the expected mineralization style and grade ranges. Analytical blanks consisted of barren quartz material used to monitor potential contamination during sample preparation and analysis.

All samples were individually sealed in heavy-duty plastic bags, labelled with unique sample numbers, and placed into rice bags for transport. Field crews maintained continuous possession of the samples until they were securely delivered by Company personnel to the SGS sample preparation facility in Grand Falls– Windsor, Newfoundland. At this facility, the samples were weighed and prepared into pulps in accordance with SGS’s standard procedures before being securely shipped internally to SGS Canada’s Minerals laboratory in Burnaby, British Columbia, for complete assay analysis.

Analytical work included:

Internal laboratory QA/QC procedures at SGS included the insertion and analysis of certified reference materials, analytical blanks, and sample duplicates alongside the submitted samples to monitor analytical accuracy and precision.

Gold and Antimony Market Commentary

Gold has recently traded at record levels, underscoring its role as a global store of value during periods of macroeconomic and geopolitical uncertainty. Spot gold was around US$5,166/oz on February 26, 2026, and Reuters has reported that gold set a record high of US$5,594.82/oz on January 29, 2026. While dayto-day pricing remains sensitive to interest rates, currency movements, and risk sentiment, current levels highlight a constructive environment for gold-focused exploration—though there is no assurance these conditions will continue.

Antimony has also drawn renewed market attention, supported by its importance in industrial applications and increasingly strategic supply-chain considerations. Fastmarkets has noted that antimony prices reached a historical high of US$59,750 per tonne on July 4, 2025, and while prices have since moderated, they have continued to trade at elevated levels relative to historical norms. Antimony is listed as a critical mineral in Canada and the US due to its importance in industrial and defense applications and increasingly strategic supply-chain considerations.
