Green Bay Copper-Gold Project

Newfoundland, Canada

Project Overview

The Green Bay Copper-Gold Project is located in the Baie Verte district of north-east Newfoundland, Canada. The province of Newfoundland and Labrador received a top-six global ranking Policy Perception Index, and top-eight global rating on the Investment Attractiveness Index, in the 2024 Fraser Institute Annual Survey of Mining Companies.

The project consists of multiple assets headlined by the Ming underground mine.

Overview

The acquisition of the Green Bay Copper-Gold Project in 2023 positioned the Company as a leading high-grade copper-gold explorer and developer in North America.

The Green Bay project is located on the Baie Verte peninsula of north-west Newfoundland, Canada. The province of Newfoundland and Labrador has been recognised as a top four global mining investment jurisdiction in the 2022 Fraser Institute Annual Survey of Mining Companies.

The Green Bay Copper-Gold Project comprises numerous assets, including:

  • Ming underground mine
  • Regional exploration tenure, which includes Rambler Ming Marwan, Little Deer and Tilt Cove
  • Pine Cove Port access
  • Nugget Pond processing facility

Ming Underground Mine

The Ming Mine is an existing underground operation located ~9 kilometres east of the township of Baie Verte. The deposit was originally mined between 1972 and 1982 before recommencing production in 2012. The deposit was successfully mined for more than a decade before production ceased in March 2023.

The Ming Mine consists of a fully operational decline accessible to 950m below surface, and an existing 650m deep shaft. This functional infrastructure provides a significant platform for FireFly to rapidly increase the Mineral Resource for minimal capital outlay and set the Company up for future mining operations. 

As announced in 25 August 2026 Mineral Resource Estimate Update, the Ming Deposit Mineral Resource has grown to 57.3Mt @ 2.4% CuEq M&I and 17.3Mt @ 2.8% CuEq Inferred. The high-grade core and VMS now totals 18.1Mt @ 4.3% M&I plus 7.0Mt @ 4.4% CuEq. This zone drives the high production years in the mine schedule and remains open with the deepest hole into the deposit intersecting 49.0m @ 6.1% CuEq. The estimate was prepared and disclosed in accordance with the JORC Code (2012 Edition) and Canadian National Instrument 43-101.

FireFly holds ~346km2 of prime exploration tenure in the heart of the prolific Baie Verte mineral district, surrounding the world-class Ming deposit. The district hosts numerous base metal volcanogenic massive sulphide (VMS) and orogenic gold deposits.  Multiple known VMS deposits in this area have been mined historically.

FireFly’s regional exploration tenure includes the Rambler Ming Marwan, Little Deer and Tilt Cove tenure.

Rambler Ming Marwan

FireFly holds a portfolio of regional exploration tenure surrounding the world-class Ming deposit. The region encompasses mafic to felsic volcanic rocks that form the core of the Baie Verte mineral district. This area hosts multiple known VMS deposits mined historically, including Ming, Rambler Main and East mines.

Little Deer

The Little Deer Copper Deposit is located 40km south of the Ming Mine and is a high-grade copper-rich VMS deposit. Two historical operations, the Little Deer and Whalesback Mines, were in operation between 1960 and 1972.

The current Mineral Resource Estimate for the Little Deer Copper Deposit contains 2.9Mt of Measured and Indicated Resources at 2.3% CuEq for 65Kt CuEq and 6.2Mt of Inferred Resources at 1.8% CuEq for 114Kt CuEq. The estimate was prepared and disclosed in accordance with the JORC Code (2012 Edition) and Canadian National Instrument 43-101. It remains open in all directions and limited exploration has been conducted in recent years.

Tilt Cove

The Tilt Cove Project is located ~30km east of the Ming Mine on the eastern the eastern coastal volcano-sedimentary rocks of the Baie Verte peninsula, which hosts significant VMS copper deposits including the historical Tilt Cove and Betts Cove mines.

The Tilt Cove Project covers an area of 115km2 and is highly prospective for volcanogenic massive sulphide (VMS) deposits similar to FireFly’s rapidly growing Ming Mine. The claims incorporate the historical Tilt Cove mine, which is a large-scale mafic hosted copper-gold VMS system. Historic production at Tilt Cove is recorded as ~170,000t of copper and ~50,000oz of gold in various mining campaigns between 1864 and 1967. Limited modern base metals exploration has been completed at the property.

The Nugget Pond Processing Facility is a 500ktpa processing plant currently on care and maintenance that consists of a conventional circuit that produces a high-quality concentrate typically grading between 27% and 29% copper.

FireFly has an agreement in place with New Found Gold Corp. (TSX-V: NFG) (formerly Maritime Resources Corp.) for access to the Pine Cove Port, located just 6km from the Green Bay Project. The agreement provides access to the Pine Cove Deep Water Port (Property) to transport and export up to 1Mt per year of mineral concentrate. The agreement also includes the right to construct storage and handling facilities on the Property.
