Great Western has 8 distinct claim groups in Nevada targeting both precious metals and base metals. Please explore each claim group and use the table below to see the different stages of exploration and subsequent evolution. Feel free to contact us with any questions you might have and we will be happy to help.

Snapshot

Black Mountain Group

Through approximately 5,000 metres of drilling, Great Western has established a copper Indicated and Inferred Mineral Resource (JORC) of 4.3 million tonnes at 0.45% copper.

Given the time and money required to establish a commercially viable copper resource, the Company has recently been concentrating on precious metals.

Great Western is seeking a strong industry partner to participate in establishing a significant copper porphyry on its claims and is in touch with a number of companies known to be interested in the area.

Key Facts

  • Based on approximately 5,000 metres of drilling
  • Target deposit in the range of 15Mt to 200Mt
  • Development partner sought
  • In touch with a number of companies known to be interested in the area

Exploration

Indicated and Inferred Mineral Resource, prepared in accordance with JORC (2012) guidelines.

Current total Resource of 4.3Mt @ 0.45% Cu, for 19kt of Cu metal (at a 0.20% Cu cut-off).

The Black Mountain copper project is open down dip towards the SE and along strike both NE and SW.

Deep Copper Target

The target is a deeply buried IP/resistivity anomaly within the diorite, down plunge from the current oxide copper resource.

The target could potentially extend the current resource a further 500m along strike with target thickness ranging from 10m to 100m.

The total target zone covers an area of approximately 2.5km2, which could host a deposit in the range of 15Mt to 200Mt.

Due to difficult ground conditions encountered the deep diorite target has not yet been reached. However our geologists have identified a number of alternative drilling strategies which may be more successful:

  1. The deep seated diorite can also be targeted from the existing copper oxide zone encountered in the Smith Mine area; this is an untried procedure but should have the advantage of testing any potential continuation of the copper mineralisation present in the Smith Mine area, prior to breaking through the Sharktooth shear zone into the diorite target
  2. A further option is to collar a hole in the east, within the Silver Bell granite, and drill westwards through the Sharktooth shear zone; the granite should provide much more favourable drill conditions compared to the Dunlap sediments

Geology

The M2 Copper Project lies within the Black Mountain Group and supports an Indicated and Inferred Mineral Resource, independently prepared in accordance with JORC guidelines. At a 0.2% cut-off grade, the current total resource is 4.3 million tonnes of 0.45% copper for 19 thousand tonnes of contained copper metal. The M2 project is open down dip towards the southeast, and also along strike both northeast and southwest.

M2 is a potential planar structure, extending 2,134 metres south southeast beneath the crest of Black Mountain to the vicinity of the historic Smith Copper Mine. The Company considers that the source of the M2 and Smith Mine copper mineralisation is an epithermal plume located beneath the “Sharktooth” peak of Black Mountain. Low grade, open-pittable copper-gold values at M2 are indicators of much higher grade and more consistent copper-gold oxide mineralisation at the intersection of the vertical northeasterly Sharktooth structure and the Diorite-Dunlap hanging wall caprock.

The M2 Sharktooth target is a deeply buried zone within the diorite, beneath the Sharktooth peak, down dip from the current M2 oxide Cu Resource. The target could potentially extend the current M2 Resource a further 500m along strike, and 500m down dip. Target thickness could range from 10m to 100m. The total target zone covers an area of approximately 2.5km2, which could host a deposit in the range of 15MT to 200MT.
