Anteros Initiates Critical Mineral Deposit Modelling at Their Havens Steady VMS Property in Newfoundland - Feb 11, 2025

Corporate Updates

ANTEROS INITIATES CRITICAL MINERAL DEPOSIT MODELLING AT THEIR

HAVENS STEADY VMS PROPERTY IN NEWFOUNDLAND

ST. JOHN’S, Newfoundland and Labrador, February 11, 2025 – Anteros Metals Inc. (“Anteros” or the

“Company”) (CSE:ANT) is pleased to announce commencement of inaugural 3D modeling at its 100%-

owned critical-mineral-bearing Havens Steady Property (the “ Property”). The Property boasts a road-

accessible Volcanogenic Massive Sulphide (“ VMS”) lead-zinc-silver ±copper-gold deposit, is close to

hydroelectric power, and is located in an established mining district in south-central Newfoundland.

Modelling of recently-digitized historical data will allow for eﬀective targeting of zone extensions and the

identiﬁcation of wider and higher -grade zones, including areas of copper -gold enrichment. Follow -up

exploration is scheduled for late spring and early summer 2025.

PROPERTY HIGHLIGHTS

• Situated in a region renowned for signiﬁcant Kuroko-type VMS deposits, known for their rich

polymetallic characteristics and signiﬁcant economic yields

• Geologically consistent mineral deposit with a 1,000- meter strike length of lead -zinc-silver

±copper-gold mineralization

• Notable high-grade intercepts (Table 1), including 2.72 metres of 2.1% Cu, 3.6% Pb, 6.17% Zn,

56.42g/t Ag and 1.82g/t Au in historical drill hole HS09-18 from 97.42 to 100.14 metres

• Road accessible and proximal to past-producing VMS mine-sites and infrastructure

• Approximately 8,150 metres of historical drilling since 1986, the most recent of which was

conducted in 2009 (approximately 1,145 metres)

• Fully permitted for exploration diamond drilling from the Mineral Lands Division of

Newfoundland and Labrador

LOCATION AND MINERAL TENURE

The Property lies 15 kilometres south of the past-producing Duck Pond lead-zinc-copper VMS mine and

40 kilometres southeast of the town of Buchans (Figure 1). The Property is comprised by seven claims

covering 175 hectares in the proliﬁc Buchans-Victoria Lake area. Hosted by rocks of the Red Cross Group

volcanic belt, the Property hosts high-grade VMS-style base and precious metal mineralization, including

critical minerals zinc and copper.

REGIONAL AND PROPERTY GEOLOGY

The Haven s Steady Property is situated within the Central Mobile Belt of the Dunnage Zone in

Newfoundland and Labrador. The region is underlain by sequences of Cambrian to Silurian volcanic and

sedimentary rocks and related intrusive rocks . Th e Property borders the Victoria Lake Superg roup, a

complex assortment of several distinct volcanic sequences, some of which host world class VMS deposits

such as the past -producing Duck Pond VMS Mine , which had reserves of 4.078 million tonnes grading

3.29% Cu, 5.68% Zn, 59.3g/t Ag and 0.86g/t Au and an additional inferred and measured 1.073 million

tonnes of 3.04% Cu, 7.05% Zn, 71.2g/t Ag and 0.8g/t Au prior to the commencement of mining operations

in 2006 (Canadian Mining Journal, Aug 1, 2006).

The Property is dominated by felsic volcanic rocks interbedded with graphitic argillites and siltstones

(Figure 2). Extensive sericitization and siliciﬁcation within the felsic volcanic units occurs with chloritic

alteration associated near zones of massive sulﬁdes and stringer sulﬁdes , including signiﬁcant

occurrences of sphalerite and galena. This geological setting mirrors that of Kuroko-type VMS deposits

known for their rich poly metallic content and signiﬁcant economic yields , as exempliﬁed by the

renowned Kuroko deposits in Japan.

Since acquiring the Property in January 2024, Anteros has performed comprehensive digital compilation

of the historical exploration data. Compilation conﬁrmed that previous geophysical work, including

airborne electromagnetics, identiﬁed multiple conductive anomalies consistent with the presence of

sulﬁde mineralization. Additionally, historic drill programs have outlined multiple zones of high -grade

lead, zinc, silver, and copper mineralization demonstrated by the presence of sphalerite and galena with

bornite and chalcopyrite in copper-rich zones. The known deposit area has a strike length of at least 1,000

metres and historic drilling shows mineralization extending to over 800 metres below surface.

Anteros has now initiated inaugural 3D modeling of the various mineralized horizons within the deposit.

This modeling eﬀort will enable precise targeting of higher-grade zones and the extension of known zones,

including those enriched with copper and gold. Drill testing is scheduled to commence in late spring/early

summer of 2025, and will become part of an inaugural mineral resource estimate.
