Kutcho Project

Kutcho is an accessible project with on-site and nearby infrastructure situated within subtle terrain

The Kutcho property is located approximately 120 km east of Dease Lake in northern British Columbia, and consists of one mining lease and 46 mineral exploration claims covering an area of approximately 17,060 hectares. The site is accessible via a 900 m long gravel airstrip located 10 km from the deposit and a 100 km long seasonal road from Dease Lake suitable for tracked and low-impact vehicles.

Property Highlights

High Grade Copper Zinc development project with 22.8 millions tonnes in the Measured and Indicated Category at 2.26% CuEq¹ representing over 1.1 billion pounds of copper equivalent contained metal (“CuEq”)¹

Top Tier Jurisdiction – situated in northern British Columbia, Canada, one of the safest mining jurisdictions globally with producing mines in the region including Brucejack (Pretium) and Red Chris (Imperial Metals)

Infrastructure – Existing field camp and airstrip; 100km of year-round ground access to be upgraded to haul road; port facilities within 400km paved highway access; subtle terrain

Permitting – Transparent and prescribed process, supportive First Nations, local stakeholders and Government. Subject only to the British Columbia Environmental Assessment review process

Exploration Upside Potential – Significant upside potential through near resource expansion and  drill infilling of current Inferred resources.  Blue sky green fields/regional exploration potential

Strong Financial support – Major Shareholders, Capstone Mining and Wheaton Precious Metals, support with financing package of C$100 million; over C$34 million already invested

Main, Sumac and Esso contain over 12 Mt of Inferred Resources that have the potential to be converted to Indicated Resources


Contains the highest grade Inferred Resource (2.15% CuEqR) and requires drilling to close out mineralization trends both up and down dip


Contains 75% of the inferred resource tonnage where definition of a potential higher grade zone may be possible with further drilling

Kutcho’s GHG Intensity

Low GHG intensity of 1.3 kg CO₂e/kg Cueq inclusive of all construction and closure requirements

Other comparative carbon intensity reporting measures place Kutcho below the median of BC operating mines where many of those mines have the added benefit of hydroelectricity sourced grid power compared to Kutcho’s reliance on site LNG generator sourced power.

Opportunities for Further GHG Reductions


1. Connection to as-yet to be developed extensions of the BC grid power network. This would also unlock potential for electrification of the mining fleet.

2. Addition of wind power to augment the LNG power plant under a remote power scenario has been determined as potentially economically viable.

3. The potential to develop CO₂ sequestration technology to permanently store CO₂ using chemical reactions that are inherent to tholeiitic basalt.

Data provided does not specify how multi-metal mines are calculated nor if the full life cycle is included. Kutcho Copper Life Cycle GHG Intensity includes access road construction, mine construction, operations, and closure with pit backfilling and is based on a cradle-to-gate calculation. Kutcho Copper is a multi-metal mine (copper, zinc, silver, and gold), so a copper equivalency is also shown based on metal value.

The Kutcho project covers 90% of the prospective Kutcho formation rocks

The prospective volcanic rocks are folded, repeating the mineralized horizon threefold on the project, including the deposit.

The long strike length of the favorable horizon and folding delivers many targets for exploration.

Mineralization & Alteration

Mineralization at Kutcho comprises three known “Kuroko-type” VMS deposits aligned in a westerly plunging linear trend. The largest, the Main deposit, comes to surface to the eastern end, followed by Sumac down plunge, and Esso to the western end which occurs at depths of about 400 m below surface.

“Kuroko-type” VMS deposits are typically related to felsic volcanism in island arc or back-arc tectonic settings. Features of the Kutcho deposits suggest that they formed at or near the water-seafloor interface in a structurally controlled depression, such as a half-graben type structure. The chemical composition of the alteration around the Kutcho deposits is well zoned about the hydrothermal vent areas. Mineralization consists of a pyritic footwall with zoned copper and zinc towards a sharp hanging wall contact.

Geophysics in exploration

Deeper penetrating ZTEM (DT/90Hz) covers 90% of the project 

has provided definition, clarity and allowed target prioritization

ZTEM can detect the Esso deposit and returns a similar ZTEM anomaly over the Esso West target

Extension of shallower penetrating VTEM surveys to compliment ZTEM data

Esso West : Exploration target

Esso West has many similarities to the Esso deposit, which was used as a benchmark

Target Development Data

2023 Aerial ZTEM survey (200m line spacing)

2023 seismic refraction surveys (500m line spacing)

2023 Aerial Magnetic survey

Surrounding drillholes (1974-2011)

Geologic mapping, 3D modelling

Mother : Exploration target

A promising geologic environment with similarities to Esso and Sumac

The western margin of the anomaly consists of a thick, coarse felsic volcanic flow dome that transitions to fine grained basin deposited rock units to the east.

The environment between the flow dome and the basin deposited rock units is an area in which productive VMS style mineralization is commonly found. This segment of the target is 2 km long.

Far East : Exploration target

3.5 km long ZTEM target along strike from known mineralization

Discreet sub-sections are also VTEM and Magnetic anomalies (signatures similar to that seen at Esso and Sumac).

Additionally, the data shows a possible fold nose target at the far eastern end which would be a new type of target for the Kutcho Project.

A single hole in 1974 was followed by three drillholes completed in 2011. The later holes intersected anomalous copper and zinc values in syngenetic pyritic mudstones. This horizon is considered the right host for VMS mineralization.
