Historic Resources at Blue Lake, additional and clarifying disclosure

Executive Summary

• Cupani Metals clarifies that the historical resource estimate for the Blue Lake project (4.37 Mt @ 0.87% Cu, 0.52% Ni, 0.84 g/t Pt‑Pd) is not a current mineral resource and cannot be relied upon without further work.
• The estimate was originally prepared in 1989 by A.T. Avison using a rectangular polygonal technique with a 60 × 60 m drilling pattern and a 1% Cu+Ni cut‑off; it remains classified as “indicated” only for historical reference.
• Cupani is actively pursuing additional drilling to verify the historic estimate and is searching for original drill logs and analytical certificates from the 1987‑88 program.

Key Details

• Historical resource (Blue Lake): 4.37 Mt grading 0.87% Cu, 0.52% Ni, 0.84 g/t Pt‑Pd (reported by A.T. Avison, unpublished La Fosse report, 1989).
• Original methodology: rectangular polygonal technique; drill spacing 60 × 60 m; cut‑off 1.5 m of 1% combined Cu+Ni; specific gravity assumed 4.6.
• The estimate was classified as “indicated” at the time but has not been verified by a qualified person and is not considered a current mineral resource or reserve.
• No current NI 43‑101 compliant resource statement exists for Blue Lake; further drilling required to substantiate any future resource claim.
• Cupani is locating original drill cores (La Fosse core on‑site) and seeking missing logs/analytical certificates from the 1987‑88 program.
• Historical context: nine mineralized lenses first drilled in the 1950s; La Fosse completed >100 drill holes (1987‑89); Rockland Mineral Corp confirmed lenses in 2011 with 16 drill holes (GM68168).
• The historical estimate has been cited in prior reports and government databases (Clark 1991, 1994) but was only used as an illustrative example of deposit type in the Retty Lake region.
• Qualified Person review: Jacquelin Gauthier, P.Geo., Vice President of Exploration, Cupani Metals Corp., NI 43‑101 qualified.
