A SOLID BASE LINE with an outstanding growth potential at the Detour-Fenelon Gold Trend ... as the deposits remains open at depth and along strike

Notes on the MREs of the Fenelon and Martiniere gold projects:

The Qualified Persons for the current MREs are Mr. Carl Pelletier, P. Geo. (For Fenelon and Martiniere) and Mr. Vincent Nadeau-Benoit, P.Geo. (For Fenelon), both from InnovExplo. The MREs follow 2014 CIM Definition Standards and the 2019 CIM MRMR Best Practice Guidelines.
These mineral resources are not mineral reserves as they do not have demonstrated economic viability.
The qualified persons are not aware of any known environmental, permitting, legal, title-related, taxation, socio-political or marketing issues, or any other relevant issue, that could materially affect the potential development of mineral resources other than those discussed in the MRE.
For Fenelon, a density value of 2.80 g/cm³, supported by measurements, was applied to the bedrock. Sixty-one high-grade zones and five low-grade envelopes were modelled in 3D using a minimum true width of 2.0 m. High-grade capping was done on raw assay data and established on a per-zone basis and ranges between 25 g/t and 110 g/t Au (except Gabbro zones where it ranged from 35 g/t to 330 g/t) for the high-grade zones and ranges between 8 g/t and 35 g/t Au for the low-grade envelopes. Composites (1.5 m) were calculated within the zones and envelopes using the grade of the adjacent material when assayed or a value of zero when not assayed.
For Martiniere, a density value of 2.80 g/cm³, supported by measurements, was applied to the bedrock. Fifty-nine high-grade zones and one low-grade envelope were modelled in 3D using a minimum true width of 3.0 m. High-grade capping was done on raw assay data and established at 35 g/t Au based on the most numerous zones and extrapolated to all zones. Composites (1.0 m) were calculated within the zones and envelopes using the grade of the adjacent material when assayed or a value of zero when not assayed.
The reasonable prospect for eventual economic extraction is met by having constraining volumes applied to any blocks (potential surface or underground extraction scenario) using Whittle and the Deswik Stope Optimizer (DSO) and by the application of cut-off grades, as shown in the above table, were calculated using a gold price of US $ 1,607 / oz and an Exchange rate of US $ 1.31 / CAD $.
Results are presented in-situ. Ounce (troy) = metric tons x grade / 31.10348. The number of tonnes and ounces was rounded to the nearest thousand. Any discrepancies in the totals are due to rounding effects; rounding followed the recommendations as per NI 43-101.
