722Kt CuEq, prepared and disclosed in accordance with the 2012 Edition of the Australasian Code
for Reporting of Exploration Results, Mineral Resources and Ore Reserves ( JORC Code 2012 ) and
Canadian National Instrument 43-101 - Standards of Disclosure for Mineral Projects (NI 43-101). The
Company has a clear strategy to rapidly grow the copper -gold Mineral Resource to demonstrate
a globally significant copper-gold asset.

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 th e 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%.
ASX: FFM | TSX: FFM | OTCPK: FFMFF
Page | 3
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 relev ant, 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

exchange fluctuations, economic, social and political conditions, and changes to applicable
regulation, and those risks outlined in the Company’s public disclosures.
The forward-looking statements and projections are inherently uncertain and may therefore differ
materially from results ultimately achieved. For example, there can be no assurance that FireFly will

development of its mineral properties will proceed, that any mineralisation will prove to be
economic, or that a mine will be successfully developed on any of FireFly’s mineral properties. The
performance of FireFly may be influenced by a number of factors which are outside of the control
of the Company, its directors, officers, employees and contractors. The Company does not make
any representations and provides no warranties concerning the accuracy of any forward- looking
statements or projections, and disclaims any obligation to update or revise any forward- looking
statements or projections based on new information, future events or circumstances or otherwise,
except to the extent required by applicable laws.
