Coppermine Geology
- All first-order controls for a sediment-hosted copper deposit – with a proof-of-concept historic drilling result
- Right time, right place: Proterozoic Era basins host some of the largest sediment hosted copper deposits
- Well-endowed district: Evidence of copper-fertile hydrothermal fluids is present throughout the project, evidenced by the numerous volcanic hosted showings
Optionality: High grade volcanic hosted vein and breccia systems with sediment hosted copper potential offers pipeline of drill targets
Large Scale Copper Potential at the Pre Discovery Stage
- Rae is less than 70km from Kugluktuk, a 24/7 airstrip and Port.
- The district is best known for the ‘Coppermine River Group’ basalts which feature extremely high grade copper showings of >45% Cu
- Rae is visually stunning with its wide spread chalcocite dominant vein systems
- The area came to the attention of European explorers in the 17th Century when tools and idols made of native copper by the local Inuit were observed
- Prospector Samuel Hearne reached the area in 1771 and reported finding a 2 kg copper nugget at surface
- Numerous locations occur throughout the project area where native copper or copper sulphides are found disseminated in sedimentary rocks – native copper was identified during the field trip.
- Modern exploration by Tundra Copper Corp. and Kaizen Discovery Corp between 2013-2015 reconfirmed the high grade volcanic hosted copper using modern lab techniques with several samples > 40% Cu and a 2015 exploration drillhole returned 28.97m at 0.57% Cu within the overlying sedimentary package, confirming the presence of sediment-hosted copper deposits.
2024 Field Campaign
- Large scale copper discovery confirmed
- Multiple high-grade copper vein systems identified
- Vision – a ±10km long NE/SW structural corridor, feeding from the Herb Dixon regional fault covering the Don and Pat project areas; results include:
- Don: 64.02% Cu & 152 g/t Ag (F005965) 62.02% Cu & 162 g/t Ag (F005966) and 50.48% Cu & 102 g/t Ag (F005959).
- Pat: 55.01% Cu (F005977), 46.07% Cu (F005984), 44.43% Cu (F005979) and 43.10% Cu (F005985)
- Rocket – an area ±400m x 200m containing dominant chalcocite vein systems: 54.12% Cu (F005950), 53.82% Cu (F005949), 53.47% Cu (F005935), 53.24% Cu (F005944) and 51.59% Cu (F005942)
- Thor – host to the historic HALO occurrence, >800mtrs of outcropping mineralization identified: 54.02% Cu (F005921), 25.7% Cu (F005922), 24.4% Cu (F005927) and 24.1% Cu (F005931)
Sample F005965 which returned 64.02% Cu and 152g/t Ag from the DON target
Sedimentary Hosted Copper
- All first-order controls for a sediment-hosted copper deposit – with a proof-of-concept historic drilling result <2km east of our licence boundary
- Right time, right place: Proterozoic Era basins host some of the largest sediment hosted copper deposits
- Well-endowed district: Evidence of copper-fertile hydrothermal fluids is present throughout the project, evidenced by the numerous volcanic hosted showings
- Optionality: High grade volcanic hosted vein and breccia systems with sediment hosted copper potential offers pipeline of drill targets

Town and Port of Kugluktuk, only 70km from the Rae Copper-Silver Project
Hulk – a district scale conductive anomaly
- Three, fault controlled, sub basins covering > 20km of strike across the Rae Group sedimentary structure within the Hulk target area
Conductivity response within the Hulk target. Elevated conductivity is observed across km’s within the Rae Group sediments, & remains open to the north into the newly acquired mineral claims
The Hulk District, covering 152 km2 and comprised of 3 sub basins. Major structures are shown which separates the basins.
Hulk – 3 distinct fault bounded sedimentary sub-basins

Inverted conductivity section along line 7740 (N/S), lookingg East through the basalt-sediment contact. A gently north dipping conductive zone over >10km, is observed through the sub basin

Stark – a target in its own right? And – it is feeding Hulk
- Herb Dixon fault: a major, regional N/S fault covering >25km through the Company’s Rae Project that intersects the Hulk area.
- It can be traced to the Vision target where assays from rock chips included results of 64.02%, 62.02%, 55.01% and 50.48% Cu
- The Stark target, situated on the Herb Dixon fault presents a highly conductive signature over more than 14km strike length and up to 2.2km wide that is coincident within a well-defined structure
Map of the Herb Dixon Fault Zone target named STARK. >14 km of N/S strike of anomalous conductivity with a zone of 7 km showing high conductivity.
Danvers – An opportunity to accelerate the pathway to an initial resource for the Rae area
- The historic non JORC resource estimate of 4.16mt @ 2.96% Cu represents the most significant deposit discovered within the broader Coppermine area
