Cadence Minerals #KDNC – Hastings Technology Metals (ASX: HAS) – Works Permit Granted to Construct the Yangibana Rare Earths Project Process Plant

Cadence Minerals (AIM/NEX: KDNC; OTC: KDNCY) is pleased to note that Hastings Technology Metals (ASX:HAS) (“Hastings”), Cadence’s joint venture partner at the Yangibana Rare Earth Project in the Gascoyne region of Western Australia (“Yangibana” “Yangibana Project”), has received a works permit to construct the Yangibana Rare Earths Project (Yangibana Project) process plant under Part V of the Environmental Protection Act 1986 (Western Australia).

Department of Water and Environmental Regulation issues works permit

Following a rigorous assessment process and a public advertisement period, the Department of Water and Environmental Regulation (DWER) has issued a works permit subject to conditions for a number of prescribed facilities (i.e. facilities that emit pollutants) at the Yangibana Project including:

  • Category 5: Process or beneficiation of metallic or non-metallic ore
  • Category 6: Mine dewatering
  • Category 52: Electric power generation
  • Category 64: Class II or III putrescible landfill site
  • Category 73: Bulk storage of chemicals etc.
  • Category 85: Sewage facility.

Of these facilities, the process plant (Category 5 under Schedule 1 of the Environmental Protection Regulations 1987) and the associated tailings storage facilities are the most important. The conditions include design and construction requirements, pollutant emission limits, monitoring requirements and compliance reporting.

The Yangibana Project includes the development of five open pit mines, groundwater abstraction, on site processing of ore, tailings storage facilities, and supporting infrastructure such as access and haul roads, accommodation facilities, administration buildings and an airstrip.

Hastings is working on satisfying the approval conditions and when completed, the work can commence subject to financial close for the Yangibana project.

Andrew Reid, Hastings Chief Operating Officer commented: “While Hastings has received State and Commonwealth environmental approvals, the additional focus and rigorous nature of this approval process on polluting facilities such as the process plant provides us and our shareholders with further confidence that the Yangibana Project is able to meet the high regulatory standards set by the Western Australian (WA) government. The regulatory standards set by the WA government also provide the international community and our major offtake customer, Schaeffler Technologies AG with assurance that the extraction component of the rare earths supply chain is undertaken in an environmentally responsible manner.”

Cadence Minerals Yangibana Holding:

Cadence owns 30% of the Yangibana, Yangibana North, Gossan, Hook, Kanes Gossan and Lions Ear Rare Earth Deposits, which form part of the Yangibana Rare Earth Deposit. Hastings Technology Metals owns the remaining 70% (“Hastings”). The updated resource ore statement can be found on the Yangibana Mineral Resource & Ore Reserve statement from 4th November 2019:

Salt Lake Potash #SO4 -Construction Begins on Australia’s First Commercial Scale SOP Evaporation Ponds



Construction Begins on Australia’s First Commercial Scale SOP Evaporation Ponds



  • Following receipt of the final approval from the Department of Water and Environmental Regulation (DWER), construction and operation of the First Phase of Lake Way Evaporation Ponds (Lake Way Ponds) at Wiluna, Western Australia has begun
  • Site support infrastructure for construction of the Lake Way Ponds is in place
  • The Lake Way Ponds will be the first Commercial Scale on-lake Sulphate of Potash (SOP) evaporation ponds in Australia. The first phase will enable de-watering of the Lake Way Williamson Pit that contains the highest grade brine resource in Australia
  • The initial ponds will have the capacity to hold the Measured Resource of 1.2GL of Williamson Pit brine at an average SOP grade 25kg/m3 which contains an equivalent of 32,000 tonnes premium SOP
  • The utilisation of the Williamson Pit brine will accelerate Salt Lake Potash’s pathway to first production of SOP at Lake Way

Salt Lake Potash Limited (Salt Lake Potash or the Company) is pleased to announce that all permits have been received from the Department of Water and Environmental Regulation (DWER) for the Lake Way Ponds at Lake Way and construction has now commenced.   

Salt Lake Potash’s Chief Executive Officer, Mr Tony Swiericzuk said: “It is a very exciting time for Salt Lake Potash as we begin construction on Australia’s first commercial scale on-lake evaporation pond system.

This is a key milestone for not only Salt Lake Potash but also for the creation of the new SOP industry within Australia.

We will continue to progress works at Lake Way on both the construction of the first phase of evaporation ponds and also on the exploration of the “whole of lake” development options which we believe will underpin a globally significant SOP operation.”

Salt Lake Potash’s immediate focus is on the rapid development of the Lake Way Project, intended to be the first salt-lake brine Sulphate of Potash (SOP) production operation in Australia. Lake Way’s location and logistical advantages make it the ideal location for the Company’s first SOP operation.

Lake Way is located in the Northern Goldfields Region of Western Australia, less than 15km south of Wiluna. The surface area of the Lake is over 270km2. The northern end of the Lake is largely covered by a number of Mining Leases, held by Blackham Resources Limited (Blackham), the owner of the Wiluna Gold Mine. The Company’s Memorandum of Understanding with Blackham (see ASX Announcement dated 12 March 2018) allows for an expedited path to development at Lake Way.

Lake Way Evaporation Ponds – Overview

The Company has now received final approval from DWER for the construction and operation of the initial evaporation ponds for Lake Way and de-watering of the Williamson Pit. 

Site support infrastructure at Lake Way has been installed enabling an immediate start on the construction works. 

Salt Lake Potash is constructing Australia’s first commercial scale on-lake evaporation ponds for a Sulphate of Potash (SOP) project at Lake Way. The initial ponds will consist of:

·      Two evaporation ponds:

(i)   Kainite Harvest Pond 500m x 500m (25 Ha); and

(ii)   Halite Pond 2,000m x 500m (100 Ha);

       ·      A 2km long and 4m deep trench will also be constructed running parallel to the ponds which will provide additional
brine feed into the pond network;

       ·      A 1.4km causeway from the Williamson Pit to the Kainite Harvest Pond; and

       ·      Associated piping and pumping infrastructure.


The design of the evaporation ponds has been led by Knight Piesold, a leading global engineering and consulting firm with extensive experience in evaporation pond design.

Both evaporation ponds will include 2m high perimeter berms with internal baffles to extend the flow path of the brine movement within the pond to optimise the evaporation process.


Salt Lake Potash is undertaking a wet hire and self-perform model for the construction of the Lake Way Ponds. This construction model allows fast track mobilisation and execution of the works, whilst providing the Company with critical hands on experience allowing testing and validating of all design criteria to de-risk the future on-lake construction.

The construction works for the pond berms involves the stripping of the sandy evaporite layer of material on the lake’s surface. A key trench will then be constructed at the upstream toe of the embankment. An excavator will borrow lakebed clays from adjacent to the embankment and spread the material within the embankment footprint to form the pond berm.

The fill will be progressively spread, air dried, rotated and mixed to bring the moisture content to an optimum level. Dewatering of the borrow pits will be conducted throughout the construction process to manage saturation levels of the fill.

The works are being completed with a number of specialized pieces of civil earthmoving equipment suited to the unique conditions, including amphibious excavators and low ground pressure equipment.

The Company has also established support infrastructure on Lake Way, comprising a site office, crib room, and full mechanical workshop with canopy capable of undertaking repairs to our fleet of equipment onsite without the need for demobilization to external repair facilities.

The initial Lake Way ponds will have a volume of 1.8GL which will be capable of capturing the total Williamson Pit Measured Brine Resource (1.2GL @ 25kg/m3 SOP equivalent).

On-going Work Program

The construction of the initial Lake Way ponds is planned to be completed by the end of Q2 2019. The de-watering of the 1.2GL of Williamson Pit brine is expected to commence towards the end of Q2 2019.
