COMPLIANCE STATEMENTS

Mineral Resource Estimate – Green Bay Project

The Mineral Resource Estimate for the Green Bay Project referred to in this announcement and set out in Appendix A was first reported in the Company’s ASX announcement dated 18 November 2025, titled ‘Mineral Resource increases 51% to 1.4Mt of copper and 1.1Moz of gold’ and is also set out in the Technical Report for the Ming Copper-Gold Mine, titled ‘National Instrument 43-101 Technical Report, FireFly Metals Ltd, Green Bay Ming Mine Copper-Gold Project, Newfoundland’ with an issue date of 1 December 2025 and a Mineral Resource effective date of 18 November 2025, available on SEDAR+ at www.sedarplus.ca.

Mineral Resource Estimate – Little Deer

The Mineral Resource Estimate for Little Deer referred to in this announcement was first reported in the Company’s ASX announcement dated 29 October 2024, titled ‘Resource Increases 42% to 1.2Mt of contained metal at 2% Copper Eq’ and is also set out in the Technical Report for the Little Deer Copper Project, titled ‘Technical Report and Updated Mineral Resource Estimate of the Little Deer Complex Copper Deposits, Newfoundland, Canada’ with an effective date of 26 June 2024, available on SEDAR+ at www.sedarplus.ca.

Metal equivalents

Metal equivalents for the Mineral Resource Estimates have been calculated at a copper price of US$8,750/t, gold price of US$2,500/oz and silver price of US$25/oz. Individual Mineral Resource grades for the metals are set out in Appendix A of this announcement.

Copper equivalent was calculated based on the formula CuEq(%) = Cu(%) + (Au(g/t) x 0.82190) + (Ag(g/t) x 0.00822).

Metallurgical factors have been applied to the metal equivalent calculation. Copper recovery used was 95%. Historical production at the Ming Mine has a documented copper recovery of ~96%. Precious metal (gold and silver) metallurgical recovery was assumed at 85% on the basis of historical recoveries achieved at the Ming Mine in addition to historical metallurgical test work to increase precious metal recoveries.

In the opinion of the Company, all elements included in the metal equivalent calculation have a reasonable potential to be recovered and sold based on current market conditions, metallurgical test work, the Company’s operational experience and, where relevant, historical performance achieved at the Green Bay project whilst in operation.

FORWARD-LOOKING INFORMATION

This announcement may contain certain forward-looking statements and projections, including statements regarding FireFly’s plans, forecasts and projections with respect to its mineral properties and programs. Forward-looking statements may be identified by the use of words such as ‘may’, ‘might’, ‘could’, ‘would’, ‘will’, ‘expect’, ‘intend’, ‘believe’, ‘forecast’, ‘milestone’, ‘objective’, ‘predict’, ‘plan’, ‘scheduled’, ‘estimate’, ‘anticipate’, ‘continue’, or other similar words and may include, without limitation, statements regarding plans, strategies and objectives.

Although the forward-looking statements contained in this announcement reflect management’s current beliefs based upon information currently available to management and based upon what management believes to be reasonable assumptions, such forward-looking statements and projections are estimates only and should not be relied upon.
