Rottenstone Northwest Project

Saskatchewan, Canada  ·  35,523 ha (86,487 acres)  ·  Cu · Au · Ni · PGE

Project Overview

Property Description

The Rottenstone Northwest Project consists of the Rottenstone North (4,512 ha) and Rottenstone West (31,011 ha) gold and base metal properties, located within the Rottenstone Domain — a regional northeast-southwest geological corridor.

The Projects are located along the same northeast-southwest trending geological structures that host multiple high-grade showings in the region, including 73.55 g/t Au over 7.5 metres at the Ranger Showing (Ramp Metals news release dated June 17, 2024) and 1.61% Cu at the Rush VMS discovery — a copper target that trends directly into Inspiration's contiguous project (Ramp Metals news release dated January 20, 2025).

Inspiration Mining is one of the largest landholders in the district, strategically positioned along trend with the camp's most active exploration corridor.

Project History

The Rottenstone Domain includes the past-producing Rottenstone nickel-copper-platinum group elements-gold mine (Ni-Cu-PGE-Au), which from 1965–1968 produced 26,057 tonnes of high-grade ore grading 3.28% Ni, 1.83% Cu and 9.63 g/t Pt+Pd+Au (Saskatchewan Mineral Deposits Index #09587).

Notably, historical work on the Rottenstone West Project identified multiple massive sulfide occurrences as early as the 1950s. These areas remain untested by modern exploration methods, presenting compelling targets for new discoveries within a top-tier mining jurisdiction.

Rush VMS Discovery Confirms District‑Scale Potential*

Ramp Metals Inc. (TSXV: RAMP) has systematically advanced its Rottenstone SW property — contiguous and on-trend with Inspiration's land position — from a surface copper discovery in January 2025 to a confirmed and growing VMS system by April 2026. Over 29 drill holes have now been completed across two seasons, with hit rates of 8/10 holes in the 2025 program and 9/9 holes in the 2026 winter program.

Rush Target — Selected Headline Results
  • Rush-001: 1.21% Cu, 9.34% Zn, 5.59 g/t Ag over 3.53m
  • Rush-002: 0.44% Cu, 3.44% Zn, 2.84 g/t Ag over 23.70m
  • Rush-009: 1.29% Cu, 12.38% Zn, 0.28% Pb, 7.47 g/t Ag over 2.55m
  • Rush-010: 0.78% Cu, 1.91% Zn, 0.53% Pb, 12.71 g/t Ag over 27.00m

The 2026 winter program intersected VMS-style mineralization in all 9 holes drilled, and identified a new deeper zone approximately 70m west of the known trend — confirming continuity and significant expansion potential. Ramp is now advancing additional targets including Redridge (2.4 km EM anomaly, soils up to 245 ppm Cu / 852 ppb Ag) and Runway (surface grabs returning Pt-Pd-Ni signatures). Assay results from the 2026 program are pending.

Latest Developments

Key Highlights

AMRT Survey Complete

Targets defined by a recent AMRT survey are located along trend and parallel to the Rush Discovery corridor, with the strongest anomalies concentrated in the southern part of the Project. Inspiration believes these represent excellent drill-ready potential — with technical teams now in the final stages of drill hole planning ahead of the maiden program.

Drill Permits Acquired

Drill permit granted for Rottenstone North. Drilling plans finalized — program expected to launch shortly.

Charles Desjardins, CEO
"We are strategically positioned along trend with recent discoveries and have cutting-edge satellite data identifying multiple gold-copper targets. Our technical team is finalizing drilling plans right now, and we anticipate launching our first drilling program shortly, at a time with historically high commodity prices."
