During October 2022, Buxton and IGO agreed on a farm-in joint venture deal encompassing 97 lode mining claims and 2 state mineral exploration permits. The Joint-Venture covers the central portion of the current project limits and contains three prospects; Bobcat, Rattler and Coyote.

All 3 prospects are buried porphyry Cu-Mo targets which all have been confirmed by drilling intersecting porphyry-style mineralisation and alteration under ~500m of post-mineralisation cover.

The Bobcat prospect contains one of the best historical intercepts achieved by Utah International in 1974, RC-UC-17 which intersected 252m @ 0.68% CuEq (0.31% Cu and 0.064% Mo).

The Bobcat target sits on the western side of the Cow Creek Fault which is interpreted to be situated on the footwall of the downthrown Rattler prospect. Buxton Resources drilled its maiden diamond drill hole program at this target and initial results aggregate a intersect of 485.85m @ 0.73% CuEq. Mineralisation was truncated by a fault at 1013.76m. Mineralisation on the footwall of the fault is weak however still proximal indicating that relative movement of the footwall is minor.

Mineralisation is hosted in disseminations and stockworking quartz veins as sulfides comprising bornite-chalcopyrite-molybdenite and pyrite. The alteration system comprises potassic minerals (mainly K-feldspar & biotite) which occur in the margins of early quartz-sulfide veins, and which occasionally completely floods the host rocks. This potassic alteration has been overprinted by structurally controlled zones of quartz-sericite-pyrite and later illite-kaolinite alteration. These alteration styles overprint host rocks comprising Proterozoic gneiss, schists, metapelites and metagranitoids which have been intruded by a diverse suite of distinct porphyritic dykes of likely Laramide age.

Rattler contains the most amount of historical drilling and has been targeted by Phelps Dodge, Utah International and Orcana Resources. The prospect contains a supergene enrichment layer of Cu-Mo which Liontown Resources Limited published an inferred resource of 40.3Mt @1.4% Cu and 0.035% Mo at a cutoff grade of 0.8% CuEq in 2009.


The Rattler project contains multiple drillholes terminated at depth in primary mineralisation and is open in most directions.  The northern end of drilling at Ratter is marked by RC-UC-01, which  intersected 216.71m @ 0.68% CuEq (0.47% Cu and 0.036% Mo) and ended its last 3m composite sample (EOH 807.72m ) included 0.28% Cu and 0.032% Mo. Historical geological logs quote “secondary biotite” at the end of the hole.  The southern margin is marked by SM-20 which constitutes the highest and thickest grade of copper, containing 243.84m @ 0.6% Cu and 0.038% Mo, this mineralisation looks to be truncated by a fault at depth.

Coyote is another area of porphyry Cu-Mo mineralisation that is identified by large low-grade intercepts in RC-UC-18 (297.18m @ 0.42% CuEq) and SM37 (305.71m @ 0.38% CuEq).

Selected assay data is available from historical drill hole, SM13 which included;

72m @ 0.48% Cu and 0.033% Mo from 629.41m

24m @ 0.61% Cu and 0.042% Mo from 675.13m to EOH.
