Project Overview

Musgrave Minerals is dedicated to safely and responsibly delivering exploration success and advance development opportunities to build a profitable gold mining business at Cue, for the benefit of our shareholders and the communities within which we operate.

Musgrave Minerals is focused on its key Cue Project in the Murchison Province of Western Australia and has additional projects in Mt Magnet region of WA and the Musgrave region of South Australia (Figure 1).

Cue Project

Musgrave commenced exploration on the Cue Project in February 2016 and subsequently acquired 100% of the key tenure at the Project in August 2017.

The Cue Project consists of the Moyagee Gold southern area and Hollandaire Copper northern area, in the highly prospective Murchison Province of Western Australia. The project has significant upside gold potential highlighted by Musgrave’s recent gold discoveries and new high-priority targets.

Musgrave made a new significant gold discovery at Cue in 2020, the Starlight discovery. The high-grade, near-surface gold mineralisation at Starlight has been a game changer for the project with the new discoveries of Starlight and White Light likely to have a huge positive influence on the economics of future development. Musgrave has grown the Break of Day resource to 797kT @ 10.2g/t Au for 262koz contained gold (see MGV ASX announcement 11 November 2020, “Break of Day High-Grade Mineral Resource Estimate”).

The Company has now grown the total resource at Cue to 12.3MT @ 2.3g/t Au for 927koz gold (see MGV ASX announcement 31 Nay 2022, “Cue Mineral Resource increases to 927,000oz”)

Musgrave’s intent is to progress development studies to fast-track long lead-time items in relation to the existing gold deposits while continuing to expand the resources and discover new economic mineralisation that will further enhance a profitable gold development.

Break of Day is still open at depth on multiple lodes and there is also significant upside at the Lena deposit where Musgrave announced a Mineral Resource update in February 2020. New insights derived from the re-interpretation of the Break of Day ore system has highlighted the huge exploration upside within the belt. We have generated new targets following the learnings from the Starlight discovery and are systematically testing these within the belt. Initial results are very encouraging with new Mineral Resources at White Heat-Mosaic and Big Sky. New gold mineralisation has also been identified at Amarillo and along the Waratah trend.

Gold discoveries such as Lake Austin North and West Island on the Evolution Joint Venture tenure show geological signs of being large, well mineralised gold systems and together with the new discoveries on the 100% MGV tenure highlight the upside potential of the Project.

In March 2019 Musgrave entered into an Option Agreement to acquire 100% of the non-alluvial gold rights to the Mainland Project directly adjacent to our 100% owned tenure at Cue. Mainland has seen very limited basement drilling but has produced significant quantities of alluvial gold.

In September 2019 Musgrave announced that it had entered into an Earn-In and Joint Venture Exploration Agreement with Evolution Mining Limited over a select area of Lake Austin and surrounds of the Cue Project in the Murchison District of Western Australia. The Evolution JV excludes all the known resources at Cue (including Lena and Break of Day) and the Mainland option area. Evolution can earn a 75% interest in the JV Area by sole funding A$18 million on exploration over a five-year term. Evolution has elected to manage the JV from 1 January 2022.

A joint venture agreement has been executed with Cyprium Australia Pty Ltd were Cyprium holds an 80% interest in the non-gold rights over the northern tenements at the Cue Project. Musgrave will retain the gold rights to gold only deposits on the tenure and a 20% free carried interest to Definitive Feasibility Study over the non-gold rights.

The Cue Project hosts a combined estimated Indicated and Inferred Mineral Resource of:

Cue Gold Project

The Cue Gold Project hosts a combined JORC (2012) and JORC (2004) compliant total Mineral Resource base of 12.3Mt @ 2.3/t Au for 927koz contained gold within a number of separate deposits: The Break of Day and Lena deposits host a significant portion of the current gold resources).

In May 2022 Musgrave announced a significant update to the Cue Mineral Resource (see MGV ASX announcement 31 Nay 2022, “Cue Mineral Resource increases to 927,000oz”).

The high-grade resources along the Break of Day trend host:

Evolution JV

In September 2019 Musgrave announced that it had entered into an Earn-In and Joint Venture Exploration Agreement with Evolution Mining Limited over a select area of Lake Austin and surrounds (JV Area) of the Cue Project in the Murchison District of Western Australia.  The JV Area excludes all the known resources including Lena and Break of Day and the Mainland option area. Evolution can earn a 75% interest in the JV Area by sole funding A$18 million on exploration over a five-year term. Evolution has recently elected to manage the joint venture.

Following initial aircore drilling in March-June 2018 a regional gold regolith “halo” was identified at the A-Zone at the Lake Austin North target. Reverse circulation (RC) drilling intersected high-grade gold in discovery hole 18MORC039; 84m @ 1.7g/t Au from 84m including 36m @ 3.6g/t Au from 111m, including a higher-grade core of 20m @ 6.1g/t Au from 116m.  Further RC results include 94m @ 2.2g/t Au from 156m (18MORC057), including 52m @ 3.8g/t Au from 198m and 29m @ 5.1g/t Au. Diamond drilling of the A-Zone at Lake Austin North has confirmed the RC drill intercepts and a northern strike and steep east dip to the mineralisation. Diamond drilling has intersected:

  • 20m @ 4.5g/t Au from 102.2m (18MODD005)
  • 242m @ 1.0g/t Au from 61m (18MODD008), including
    • 45m @ 3.3g/t Au from 70m and 5.8m @ 4.5g/t Au from 199.8m
  • 9m @ 2.0g/t Au from 85.8m (19MODD013)

The basement mineralisation has now been defined over a strike length of 500m and is open to the north, south and down dip. Evolution have committed to a large regional aircore drilling program (>40,000m) and basement follow-up diamond drilling.

Aircore drilling has extended the A-Zone gold “halo” over a strike of more than 3km where it remains open to the north. This regional scout geochemical drilling has also defined multiple zones of regolith gold anomalism that now have a combined strike extent of >8km.  This suggests the likelihood of multiple basement sources for the dispersed regolith gold. Further drilling is required.

An economic gold deposit may have a regolith footprint of only a few hundred metres.

Commencing in 2021 and continuing into 2022, Evolution is drill testing the West Island aircore gold anomaly with diamond drilling and has intersected high-grade gold mineralisation hosted within a differentiated dolerite in fresh rock. Intersections include:

  • 4.26m @ 41.5g/t Au from 160.74m (21MODD025), including
    • 41m @ 400.2g/t Au from 160.74m
  • 5m @ 3.2g/t Au from 245m (21MODD006), including;
    • 3.0m @ 10.6g/t Au from 247.5m
  • 11m @ 3.6g/t Au from 272m (21MODD001), including;
    • 5.0m @ 5.5g/t Au from 276m

Aircore drilling on the joint venture also extended the regolith gold anomaly at West Island with regolith mineralisation now extending over a 1.6km strike where it remains open. Intersections include:

  • 67m @ 0.82g/t Au from 87m to EOH (21MOAC018) including:
    • 44m @ 1.17g/t Au from 87m
  • 67m @ 0.87g/t Au from 88m to EOH (21MOAC019) including:
    • 12m @ 3.33g/t Au from 108m
  • 46m @ 0.72g/t Au from 96m (21MOAC020) including:
    • 20m @ 1.46g/t Au from 110m
  • 68m @ 1.49g/t Au from 110m to EOH (21MOAC024) including:
    • 12m @ 4.41g/t Au from 134m
  • 53m @ 2.01g/t Au from 108m to EOH (21MOAC025)

 

Hollandaire Copper Project

The Hollandaire Copper Project was discovered by Silver Lake Resources Limited in 2011 and hosts a JORC (2012) compliant total Mineral Resource Estimate of 2.8Mt @ 1.9% Cu for 51,500t of contained copper and 574,000oz contained silver @ 6.4g/t Ag (refer CYM ASX announcement 29 September 2020, “Hollandaire Copper-Gold Mineral Resource Estimate”).

The Hollandaire and Hollandaire West deposits are tabular strata bound volcanic-hosted massive sulphide deposits (VMS). The mineralisation forms a moderate dipping zone of massive sulphide mineralisation averaging 10 metres thick that plunges to the south-west. Copper mineralisation is located approximately 50m from surface and drilling to date indicates it is open to the south-west and at depth.

Cyprium Australia have acquired 80% of the rights to these resources. Musgrave will retain a 20% free carried interest in the non-gold rights and retains 100% in the gold rights for gold dominant deposits.

Mt Magnet South Project

In March 2022 Musgrave Exploration Pty Ltd, a wholly owned subsidiary of Musgrave Minerals Ltd, entered into a Sale and Purchase Agreement to acquire 100% of the Mt Magnet South Project. The Project is located within trucking distance of the Company’s Cue Gold Project in Western Australia’s Murchison goldfields and just 5km south of the township of Mt Magnet.

The Mt Magnet South Project comprises a group of 19 semi-contiguous prospecting and exploration licences covering an area of approximately 294km2 almost doubling Musgrave’s landholding in the Murchison.  The Project is an early stage, under-explored greenfield opportunity, in a good location with excellent nearby infrastructure.

The project provides an additional opportunity for Musgrave to apply the significant exploration learnings from its discovery success 40km to the north at the Cue Project and make further discoveries in the Murchison. Future discoveries have the potential to add to the Company’s growing resource base in the region thus enhancing the value of the Cue Gold Project.

Musgrave Province

The Musgrave Province is one of the last under-explored frontiers in Australia in terms of mineral exploration and is prospective for a number of commodities. The centre piece is the recognition of, and access to, the under-explored potential of the Giles Complex, a 1080Ma aged mafic-ultramafic layered intrusive complex that hosts the massive Nebo-Babel deposit, a major nickel and copper sulphide deposit in the Western Australian portion of the province.

In South Australia, the Musgrave Province lies almost entirely within Anangu Pitjantjatjara Yankunytjatjara (APY) land (Aboriginal freehold land). Musgrave currently hold a number of exploration licence applications in the province. This project is available for joint venture or sale.
