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

Mineral Jackpot Group

Great Western field surveys have doubled the potential mineralisation over 5 adjoining, historic gold and silver mines and drilling is planned.

The discovery of 51 spoil heaps at historic mine workings, potentially covering 14,000 m², also gives Mineral Jackpot shorter term precious metals processing potential.

In 2020 Great Western produced a small doré bar and a commercial project is at an advanced planning stage.

Exploration

Mineral Jackpot offers both exploration potential aswell as shorter term precious metals processing from spoil heaps from historic mine workings.

Exploration

Mineral Jackpot consists of five adjacent historical gold and silver mines in mountainous terrain. Recent field surveys have doubled previously-mapped mineralisation.

Ground based magnetic survey over Mineral Jackpot and the broader Black Mountain claim group are nearing completion and drilling is planned.

Precious Metals Processing

In late 2020 Great Western extracted spoil heap material at historical gold and silver mine workings in the Mineral Jackpot Group, producing a small doré bar made up of gold, silver and other minerals.

This has proved the initial concept of spoil heap recovery in the area.

135kg from the same load was air-freighted to the UK and extensively tested over a 4-month period in a specialised laboratory.

Lab analysis concluded that a relatively straightforward gravity separation operation could economically produce commercial quantities of gold and silver and would be effective for this particular material and maybe subsequently enhanced by a cyanide-leaching operation.

A Consultant Metallurgist has been engaged by the Company to formulate a first stage commercial project, the preliminary design stage of which is now complete.

Project design envisages new prices for equipment, whereas capital cost may be reduced with good quality used equipment, widely available in the area and currently being sourced.

A summer 2021 field trip revealed that the spoil heaps are materially more extensive than previously calculated, with 51 heaps in total, potentially covering 14,000 m² (previously 38 heaps covering 5,000 m²).

Processing may be simplified by producing concentrate and selling it to a refinery rather than pouring precious metals in a remote location which has associated security risks.

Costs and logistics of bringing raw material off the mountain are the main limiting factor in development of a gravity separation project and are being carefully factored into plans.

Great Western has a target range of 50,000 - 100,000 oz gold for Mineral Jackpot. 

Geology

Geological mapping at the Mineral Jackpot target indicates the presence of mineralised sheeted quartz veins in host granite, prospective for narrow vein, high grade precious metals. Grab sampling of spoil dumps from former workings carried out in 2015 by Great Western yielded results of 5.6 g/t Au and 19.1 g/t Au.

Historic geological reports point to at least 7 subparallel lodes, prospective for Au-Ag-U mineralisation in both the quartz veining and the surrounding altered vein selvedge. Historical production has left numerous residual shafts and adits covering an area of approximately 0.5km2.

In 2018 the company added 66 new claims to the eastern side of the Black Mountain Group. These claims cover the Silver Moon and Silver Bell prospects which have been historically worked for gold and silver.

More recent grab sampling by Great Western personnel has yielded gold grades of 15.2 g/t Au and 95.6 g/t Au, within in-situ vein material at the Silver Bell and Silver Moon prospects, highlighting the untapped potential of this area.

Soil sampling conducted in 2019 focused on identifying strike extensions of existing known veins, along with the testing of ground between the Mineral Jackpot and Silver Bell deposits. The soil sampling programme has approximately doubled the previously defined mineralisation footprint at Mineral Jackpot, with over 2km of strike length now exposed.

There is strong evidence to suggest that there is further previously undefined mineralisation between the Cabin Rock area, and the main workings, as well as a continuation of the Cabin Rock mineralisation towards the southeast.
