Project Overview

Musgrave Minerals is dedicated to discovering new deposits of economic mineralisation and growing its gold resource base using systematic, well-resourced exploration methods and programs. Musgrave Minerals is focused on its key Cue Project in the Murchison Province of Western Australia with additional projects in 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 within the Project in August 2017.

The Cue Project consists of the Moyagee Gold southern area and Hollandaire Copper norther area in the highly prospective Murchison Province of Western Australia. The project has significant upside gold potential with recent gold discoveries and new high-priority targets. Musgrave’s intent is to grow the existing resources and discover new economic mineralisation that could underpin a profitable gold development. An initial high-grade resource was estimated for the Break of Day deposit in 2017 following the discovery.  Break of Day is still open at depth with significant potential to grow the resource highlighted by recent (Dec 2019) hits such as 45m @ 11.8g/t Au (19MORC037) in what could potentially be a new structural position.  There is also significant upside at the Lena deposit where drilling is continuing with the aim to grow the resource. New gold discoveries such as Lake Austin North show geological signs of being large, well mineralised gold systems capable of delivering significant resource upgrades.

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.

An option agreement has been executed with Cyprium Australia Pty Ltd were Cyprium can earn an 80% interest in the non-gold rights over the northern tenements at the Cue Project. Musgrave will retain the gold rights to the tenure and a 20% free carried interest to Bankable Feasibility Study on the non-gold rights.

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

Moyagee Gold Project

The Moyagee Project hosts a combined JORC (2012) and JORC (2004) compliant total Mineral Resource base of 3.87Mt @ 3.07g/t Au for 382,0000oz contained gold within four separate deposits: Break of Day, Lena, Leviticus, and Numbers (refer MGV ASX announcement 15 October 2018 “Annual Report”).

Break of Day is a new high-grade gold discovery with potential to grow through further drilling. The mineralisation is currently open down plunge and a new potential ‘link-lode’ has been identified in drill hole 19MORC037 which intersected 45m @ 11.8g/t Au at 144m down hole.  This is outside the current resource interpretation and has the potential to add significant upside to the deposit. Further drilling is being planned.

  • 45m @ 11.8g/t Au from 144m (19MORC037)

The Break of Day mineralisation consists of two parallel sub-vertical high-grade gold quartz lodes traced over a combined strike length in excess of 400m.

In July 2017 Musgrave announced a significant update to the near-surface Lena Resource and is continuing to drill at Lena with a new resource update expected in Q1 2020.

New Lake Austin North Gold Discovery 

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 with a minimum commitment of A$4 million in the first two years. Musgrave will manage the JV during the initial period. As part of the Agreement, Evolution has agreed to subscribe for 18,587,361 ordinary shares in Musgrave through a share placement (“Placement”) at a price of $0.0807 per share. The placement was set at the 30-day VWAP for Musgrave shares and represents a holding of 4.59% (undiluted) in the Company.

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) and
  • 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.

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.

Hollandaire Copper Project

The Hollandaire Copper Project was discovered by Silver Lake Resources Limited in 2011 and hosts a JORC (2004) compliant total Mineral Resource base of 2.0Mt @ 1.9% Cu for 38,800t of contained copper and 2.7Mt @ 5.8g/t Ag for approximately 495,000oz contained silver and 0.52Mt @ 1.35g/t Au for 22,500oz contained gold (refer SLR ASX announcement 26 August 2016: “Mineral Resources and Ore Reserves Update”).

The Hollandaire and Hollandaire West deposits are tabular stratabound 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 an option to acquire 80% of the non-gold rights to these base metal resources. Musgrave will retain a 20% free carried interest in the non-gold rights and retains a 100% in the gold rights.

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.
