Mineral Resource Estimate

CSE: MLM

OTCQB: MLMLF

Significant scale and grade underpin strong project fundamentals

Demonstrated economic potential across open-pit and underground zones

Robust, NI 43-101–compliant foundation for development and growth

Detail Mineral Resource Estimate within pit shell + underground shapes

(OP= Open Pit, UG= Underground, Mt= Millions tonnes, Moz= Millions Ounces, Au= Gold metal)

Note 1: Mineral Resource Statement Notes CIM definition standards were followed for the resource estimate.

This Mineral Resource has an effective date of September 29, 2025.

The 2025 resource models used ordinary kriging (OK) grade estimation within a three-dimensional block model with mineralized domains defined by wireframe solids.

Mineral resources are constrained within pit shells (OP) and Underground Shapes (UG)

Open pit cut-off of 0.25 g/t Au milled is based on the cost/tonne ($USD/t) milled for incremental mining, processing, and G&A

Underground cut-off of 1.85 g/t Au milled is based on the cost/tonne ($USD/t) milled for incremental mining, processing, and G&A

The 0.25 g/t Au cut-off for OP and the 1.85 g/t Au cut-off for UG used for reporting is based on the following:
a. Long term Gold price of US$2,500/oz
b. Metallurgical recoveries are based on metallurgical testing recovery of 92%
c. Average Bulk density (specific gravity) was determined for each lithology and/or mineralized domain within the deposit
d. Processing costs of USD$11.00/t, G&A costs of USD$4.00/t, and Tailings Fee of USD$2.00/t milled
e. Dilution of 5% for OP, and 10% for UG
f. Overall Pit Slope angle of 47 degrees

Mineral Resources that are not mineral reserves do not have economic viability. Numbers may not add due to rounding.
