The Kangan Project is 80 km immediately south of Port Hedland (tenements overlaying 1:500,000 GSWA geological map) showing the 3.0-2.9 Ga age De Grey Group (being the age of the Witwatersrand Supergroup in southern Africa). Yellow diamonds are recorded gold workings. The figure also shows Pioneer’s initial gold targets based on data and records of past explorers including the mine operator of the Womerina Alluvial Gold Mine, which is partly within Pioneer’s tenements.

The Kangan Project (E45/4948, E47/3318-1 and E47/3321-1) is located 80 km south of Port Hedland in the western Pilbara region of Western Australia.

Interest in the Pilbara region for gold has recently surged as explorers test the hypothesis proposed by Dr Quinton Hennigh¹ of Novo Resources Group, that:

  • Some of Earth’s earliest land masses (cratons), including Kaapvaal (Southern Africa), Dharwar, Singhbhum and Bastar (Indian subcontinent), and Pilbara (Australia) existed as a single continent, referred to as Ur by some authors including Hennigh;
  • The remnants of the Ur continent have contributed approximately 1.85, 0.35 and 0.1 billion oz gold production, respectively, or about 39% of historic global gold production, estimated to be about 5.9 billion oz [World Gold Council, 2014]. About 75% of this gold has come from the Witwatersrand Basin;
  • The hypothesis contends that huge quantities of gold were scavenged out of seawater by microbial mats starting at around 3.0-2.9 billion years before present (Ga), initiating a crustal gold depositional event. If this method of gold deposition extended throughout the proposed continent, the Pilbara region is under-represented as far as gold production is concerned.

Lithified sediments within the 3.0-2.9 Ga age (being the age of the Witwatersrand Supergroup in southern Africa, and the age-equivalent De Grey Group in the Pilbara)² are currently the targeted rock units receiving exploration interest in the Pilbara, and rocks of this age are mapped within Pioneer’s Kangan Project (Refer to GSWA 1:100,000 Satirist sheet.)

Kangan Project and the West Pilbara Sediment-hosted Gold Model: Gold Targets and Gold Nuggets

The tenements held by Pioneer are adjacent to the areas held by Novo Resources Group; and De Grey Mining Limited in joint venture with Kirkland Lake Group.

On 6 October 2017 the Company announced that the Kangan Project had records from earlier explorers indicating wide-spread gold anomalism within the project’s south western and northern tenement areas (Figure 1) including:

  • Rock chips up to 2,730ppb (2.73 g/t) Au;
  • anomalous stream sediment geochemistry values up to 254ppb Au, and
  • two (2) widespread soil geochemistry anomalies with peak values of 2,640ppb (2.64 g/t) Au) and 2,654ppb (2.65 g/t) Au) respectively.

The Kangan Project also covers parts of the Womerina Gold Mine alluvial field. Reports from the late 1980s through to 2010 record exploration and mining activities including a medium scale alluvial and elluvial gold recovery operation treating gravels derived from the De Grey (Mallina) Formation and Millindinna Intrusion sequence.

The following targets are evident from the records of earlier explorers:

  • Target 1: A 0.85 km target with rock chips up to 2,730ppb (2.73 g/t) Au and stream sediment geochemistry values up to 254ppb Au
  • Target 2: A 0.65 km target with gold in soils (peak value 2,640ppb (2.64 g/t) Au) at the base of felsic volcanoclastic conglomerate and pebbly sandstone; open to the north
  • Target 3: A 3 km long target with gold in soils (peak value 2,654ppb (2.65 g/t) Au), striking sub-parallel to multiple stratigraphic units open to the north east
  • Target 4: Gold workings, likely for alluvial gold. Project rock-types include units of the Fortescue Group and De Grey Group (Mallina formation, Constantine sandstone/conglomerate and Honeyeater basalt)
  • Target 5: Pioneer geologists have confirmed the presence of prospective pegmatites near where the Eastern-most tenement application abuts the Wodgina Lithium Mine tenements

Outlook

Pioneer has engaged with 4 groups of prospectors who plan to metal detect over gold targets, logging and mapping locations of discoveries.

Company contractors are also scheduled for on-site fieldwork again later this year, to conduct further reconnaissance mapping, sampling and prospecting within the Kangan tenements. One of the aims of the work will be to establish the host rock/s for in-situ gold mineralisation.
