From grid to target.

The Company’s 2024 program established systematic geochemical coverage across three grids, confirmed the strength of known showings, and defined new copper and gold anomalies for follow-up.

GPS-Surveyed Grid Lines

Executed March 7 to June 1, 2024 by Rio Minerals Ltd. with a geologist and a four-person field crew — soil grids on 50- metre stations, stream-sediment sampling of first- and second-order creeks, prospecting, and three petrographic samples.

All samples were analyzed at Activation Laboratories in Kamloops, B.C. (ISO/IEC 17025 accredited), using 36-element ICP-OES with gold by fire assay. The Qualified Person visited the property during the program and collected ten independent verification samples.

SOUTH

South Grid — Cow area. Gold-in-soil anomalies to 721 ppb Au along line 24950E, coincident copper anomalies, and a northeast- trending zinc trend.

NORTH

North Grid. Gold-in-soil to 218 ppb Au; multi-line copper anomalies coincident with barium and zinc trends and anomalous gold in silts.

EAST

East Grid — Pogo SE area. Copper-in-soil to 262 ppm near rock sample 181434 (2,840 ppm Cu); a coincident Cu–Ba anomaly across three lines in the southeast.

Checked against the certificate.

The Qualified Person collected ten check samples at Company sample sites and compared 35 database assays against original laboratory certificates, detecting no discrepancies. The author’s check samples confirmed — and at several sites exceeded — the Company’s reported grades.

A defined Phase I follow-up program.

The technical report recommends compilation, detailed mapping, expanded geochemistry, and ground geophysics to trace the gabbro-associated mineralization and test the new anomalies.

Phase I exploration allocation as referenced in the Company’s listing-grade documentation.

FIELD PLAN

CAD ≈ 178,775

Rio Minerals proposal dated July 10, 2025 — grid establishment, trenching, ground magnetics, geochemistry, GIS compilation, and reporting.

METHODS

Map · Soil · Mag · Trench

1:2,000-scale mapping, 25-m infill soils, magnetics over the South and North grids, and biogeochemistry where exposure is poor.

Implementation of any portion of the Phase I program is subject to available funding, permitting where applicable, and the Company’s discretion.
