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.


Olympic Gold (OG)

The Olympic Gold Project, like Great Western’s 16,400 acres in south-west Mineral County, lies within the Walker Lane Fault Belt, a major metallogenic belt host to world class gold, silver and copper deposits.

Included within the Olympic claims is OMCO. The OMCO Mine produced gold at 25-30 grams/tonne recovered and silver at 30 grams/tonne recovered between 1918 and 1939 from 900 metres of underground workings.

The Olympic claims are situated at the intersection of 2 major gold trends; the north-south  Rawhide - Paradise Peak - Tonopah trend and the east-west Aurora – Borealis - Santa Fe - Round Mountain trend.

In 2021 Great Western drilled a number of targets at Olympic, with encouraging results. Follow-up drilling in 2022 is complete. Drilling in 2022 intercepted the OMCO Mine vein and an extension to the OMCO Mine is now established.

Field work has also located a very large tailings heap dating from the abandoned OMCO Mine, together with a significant stockpile of material which was never processed when the mine was in production. An initial survey of the tailings heap shows it to cover a surface area of approximately 11,000m². Western Milling LLC created in September 2022 for recovery of precious metals from pre-mined materials.

In November 2022 Great Western announced the results of an independent initial Mineral Resource Estimate for the Olympic Gold Tailings project as well as Exploration Targets for stockpile and spoil material at the Olympic Gold Project and Mineral Jackpot Project. All resources and exploration targets are reported in accordance with the JORC code (2012). The announcement can be viewed here.

Olympic Gold offers considerable exploration potential along with early production opportunities.

  • Best intercept 8.90 g/t Au in shallow zone at Trafalgar Hill
  • Follow-up drilling in 2022 complete at OMCO and Trafalgar Hill
  • Drilling in 2022 intercepted the OMCO Mine vein and an extension to the OMCO Mine is now established
  • Early production potential from tailings and stockpile material
  • Target range 450,000-1,250,000 oz gold



In 2021 Great Western drilled 3 targets at Olympic:

  1. OMCO
  2. Trafalgar Hill
  3. West Ridge

In 2022 Great Western drilled 2 targets at Olympic:

  1. OMCO
  2. Trafalgar Hill


  • The OMCO Mine produced gold at 25-30 grams/tonne recovered & silver at 30 grams/tonne recovered until the 1940s and was abandoned at the point where productive veins mined from west to east encountered a northsouth fault
  • Additional claims were staked to the east of the OMCO Mine in 2021
  • 2021 drilling: 4 holes totalling 971 metres
  • A major breakthrough was achieved in 2021 when Great Western’s drill programme established evidence of an extension of the OMCO Mine vein through analysis of mineralisation in drill cuttings
  • In addition to drilling east of the fault, two holes were drilled to the west of the fault and close to the OMCO Mine, yielding reportable grades of gold
  • 2022 drilling: 10 holes totalling 1,339 metres, with 4 further very shallow holes
  • Drilling in 2022 intercepted the OMCO Mine vein and an extension to the OMCO Mine is now established.

Trafalgar Hill

  • Prospects identified through geological mapping and magnetometer surveys
  • 2021 drilling: 6 holes totalling 1,352 metres
  • Six holes were drilled in 2021 to test deep and shallow targets resulting in high-grade gold intercepts
  • Best intercept 8.90 g/t Au in shallow zone
  • Further holes will track veins to south and southeast of the existing shallow zone intercepts
  • The deeper target prevails in the north of Trafalgar Hill and is a potentially larger structure than the shallow zone, while assay results have reported lower grades
  • In the deeper zone an Induced Polarisation survey will be carried out for better target definition prior to further drilling
  • 2022 drilling: 3 holes totalling 430 metres
  • The lithology and alteration were successfully predicted and the target horizon encountered in all three holes
  • In the third hole, OMRC014, this horizon was thicker than previously encountered and more pyrite impregnation was observed in the underlying rhyolite.

West Ridge

  • The West Ridge prospect has previously been mined for gold
  • Magnetic survey indicated mineralisation
  • 2021 drilling: 1 hole totalling 152 metres
  • Single hole drilled did not encounter reportable gold
  • However, analysis of drill cuttings indicates possible presence of a deeper epithermal vein, which will be tested by a follow-up, deeper hole

Great Western has a target range of 450,000-1,250,000 oz gold for Olympic.


The 825-acre Olympic group of claims are located on  the northern flanks of the Cedar Mountain range in centraleast Mineral County. The mineral deposit type at Olympic is of low sulphidation epithermal banded quartz gold vein style.


1 - OMCO Mine Extension

- Extension of the remaining OMCO Vein across unexplored fault blocks to the south and west of the mine workings.

- Follow up parallel vein sets both above and below the OMCO Vein indicated by historic drilling, such as the Cosmos Vein.

2 - East OMCO Fault

Continuation of OMCO Vein deposit displaced southeast by the OMCO Fault. Unexplored fault has potential to be mineralised feeder structure host to larger size deposit than OMCO Vein.

3 - OMCO Tailings

Re-evaluation of historic tailings deposit of ~41 kt @ 1.67 g/t Au.

4 - Trafalgar Hill

Extension of two outcropping gold-quartz veins along strike and at depth beneath Quaternary cover.

5 - West Ridge

Area of gold quartz veining, potentially a westerly extension of the OMCO vein. May also be associated with mineralisation seen at Trafalgar Hill to the northwest, with significant post-mineralisation cover occurring between the two prospects.

6 - Middle Hills

Large footprint of strong silicification and phyllic alteration associated with gold-quartz veining, gossans and breccias.

7 - East Gully

Similar characteristics to Middle Hills with further intersecting fault orientations adding likelihood of hydrothermal fluid transport and mineral deposition. Placer gold has reportedly been recovered from the target and has potential to link to Middle Hills.

8 - Rhyolite Dome

Area of gold-quartz veining and brecciation associated with silica flooding.
