Overview

A High-Grade Discovery Opportunity.

RDP is a 100% owned copper-gold porphyry project in British Columbia’s Golden Horseshoe, at the southern end of the Toodoggone Mining District. Four target areas—Day, Bird, Porcupine and Roy—sit within the property.

At Day, hole RDP-25-011 returned 112.2 metres of 1.35% CuEq² or 2.02 g/t AuEq³ within 405.0 metres of 0.71% CuEq². The planned drill program is focused on testing the interpreted porphyry centre between the western and eastern magnetic lobes while more fully defining the 2025 western-lobe discovery.

DRILLING TOWARD THE INTERPRETED PORPHYRY CENTRE

2026 Program

Closing the Gap at Day

  • Approximately 3,000 metres planned to test the interpreted porphyry centre between the western and eastern lobes.
  • Follow-up drilling designed to more fully define the 2025 western-lobe discovery.
  • High-resolution magnetics, magnetic-vector-inversion modelling and IP used to refine the target.
  • Exploration agreements in place with Takla Nation and Tsay Keh Dene Nation.

Strategic Context

In an Active B.C. Copper District

RDP lies 40 kilometres west of Kliyul in a district surrounded by senior-company investments and joint ventures. Pacific Ridge has granted Minsur a right of first refusal, for a period of nine months, to acquire the RDP copper-gold project.

01

Property and Geological Setting

RDP covers more than 10,000 hectares, 40 kilometres west of Kliyul. The property lies in the Stikine Terrane and is underlain by Lower Jurassic Hazelton Group volcanic and sedimentary rocks together with Late Triassic-to-Early Jurassic intrusive rocks.

Four porphyry copper-gold targets—Roy, Day, Porcupine and Bird—have been explored intermittently since the early 1970s using mapping, geochemistry, geophysics, trenching and limited drilling. RDP was under option to Antofagasta Minerals from 2022 through 2024.

Program Highlights

  • Five holes totalling 1,392 m were drilled at Day in 2022. RDP-22-005 returned 107.2 m of 1.39% CuEq² or 2.06 g/t AuEq³ within 497.2 m of 0.66% CuEq² or 0.97 g/t AuEq³.
  • Two holes totalling 987 m were drilled at Day in 2023. RDP-23-007 ended in 19.0 m of 0.45% CuEq² or 0.67 g/t AuEq³ and supported a steeply north-dipping, tabular porphyry interpretation.
  • Five holes totalling 2,156 m were drilled at Day in 2025. RDP-25-011 returned 112.2 m of 1.35% CuEq² or 2.02 g/t AuEq³; RDP-25-012 returned 154.7 m of 0.63% CuEq²; and RDP-25-014 returned 130.8 m of 0.47% CuEq².

03

Roy Target

Roy hosts quartz-magnetite-chalcopyrite stockwork in monzonite. A 1990 trench returned 0.121% copper and 0.55 g/t gold over 62 m; EQ-11-01 returned 0.11% copper and 0.64 g/t gold over 122.95 m.

04

Porcupine Target

Originally explored as a stratabound massive-sulphide target, Porcupine returned historical float values as high as 17.2% copper. Later interpretation of alteration and soil geochemistry suggests an epithermal system potentially related to an underlying porphyry.

05

Bird Target

Bird lies between Roy and Porcupine. Mapping identified chalcopyrite-bearing vein stockwork and potassic alteration where porphyry dykes intrude prospective volcaniclastic rocks.
