IGO has earned 51% and committed further capital to increase to 70%, validating the scale and potential of the system.

Major Partner Endorsement

Sole-funded drilling delivered large-scale porphyry intersections, including 405m @ 0.35% Cu and 0.045% Mo — confirming a significant mineralised system.

Strong Drill Results

Located in the highly endowed SW USA porphyry belt, home to multiple large operating copper mines.

World-Class Copper Address

Buxton is free-carried through this earn-in phase while retaining exposure to the core system and 100%-owned surrounding exploration ground.

Copper Wolf represents a compelling opportunity to gain exposure to a major-backed copper discovery in a globally significant district. With strong technical validation, committed funding from IGO, and significant exploration upside across both JV and 100%-owned ground, Buxton is well-positioned to unlock further value.

Geological mapping and drillhole logging has confirmed porphyry-style mineralisaiton and alteration within the project area. Age dating has resulted in a 69.3Ma date which is concurrent with the 50-80Ma mineralizing event throughout the Laramide Arc in the southwest US.

Lithogeochemical relationships between porphyries intersected by Buxton’s CPW0002DD at Bobcat with mapped outcropping porphyritic rocks at Buxton’s regional prospects show strong correlation, possibly indicating 

multiple emplacements of porphyry-intrusion centres hosting mineralisation within the project.

Advancing a Major-Backed Copper Opportunity in Arizona

Copper Wolf (JV) is a large-scale porphyry copper–molybdenum system located in one of the world’s most prolific copper belts. Backed by IGO and supported by strong drilling results, the project offers leveraged exposure to a globally significant copper district with meaningful upside and reduced balance sheet risk.



 This asset has been disposed of as of 29th June 2026.  Buxton announced completion of the sale of its 49% co-ownership interest in the Copper Wolf Project joint venture assets to IGO US Project LLC, a wholly owned subsidiary of IGO Limited (ASX: IGO).

The Copper Wolf (JV) Project is a large Laramide-age (70.3 Ma) porphyry copper–molybdenum system in Arizona, USA - a premier global copper jurisdiction.

Following successful drilling, IGO earned a 51% interest and has committed A$5.35M to increase its stake to 70%. Buxton retains a significant interest in the JV and 100% ownership of surrounding highly prospective tenure.

Copper Wolf (JV) provides exposure to a proven copper system with major-partner validation and modern exploration targeting.

The Copper Wolf Project lies within the NW-SE striking Laramide Arc which hosts multiple world class copper-molybdenum porphyry deposits.

Project geology is composed of variably metamorphosed orthogneissic granites, schists and mafic dykes which has been intruded by Late-Cretaceous intrusive rocks hosting porphyritic series of intrusives encompassing Copper-Molybdenum mineralisation. A later Tertiary-aged extensional event has pulled geology in a NE-SW direction creating a series of NW-SE striking normal faults resulting in a sequence of horst and grabens. Coeval volcanic rocks conceal mineralisation up to 500m in the central portion of the project.
