Dandaragan Trough Project (DTP)

Dandaragan Trough Project (DTP) (PWN 100%)

  • Covers 130km2 of exploration licences, in Western Australia.

  • The Dandaragan Trough hosts one of the world’s largest glauconite/greensands deposits, containing abundant phosphorus and potassium.

  • The DTP has excellent connectivity to transport facilities, infrastructure and proximity to local and regional markets.  

Resource Delineation 

  • Widths greater than 20km 

  • Many intersections greater than 40m thick

  • Regionally extensive - extends ~150km along strike


Resource Appraisal

  • Indicated + Inferred Potash Resource – 910 Mt @ 3.8% K2O, and 

  • Indicated + Inferred Phosphate Resource – 630 Mt @ 1.9% P2O5. 

  • Resource covers 52 km2 area (ASX release, 26 Sept 2017).

  • Dambadgee – Recent drilling results suggest that the Dambadgee prospect may represent a higher quality resource than Dinner Hill.  Exploration Target of 2 to 4 billion tonnes reported 28 Sept 2017.

Photograph of Dambadgee drill samples, showing thick sequences of fresh greensands, from 42 metres to 102 metres, separated by chalk from 50 to 60 metres.  Oxidised overburden from surface to 42 metres, means a waste:ore ratio of 0.8:1.

Acquisition Rationale

The objective is to produce phosphate and sulphate of potash fertilisers and a range of valuable by-products from the phosphate and glauconite present within the sediments of the DTP through the application of the K-Max® technology.


Forward Plan

  • Parkway Minerals is exploring various pathways to introduce a joint venture or strategic partner to fund the next stage of feasibility studies, or potentially monetise the project interest.
