Pilgangoora Lithium-Tantalum Project


Pilbara Minerals’ 100%-owned Pilgangoora Lithium-Tantalum Project (Pilgangoora Project) is located 120km from Port Hedland in Western Australia’s resource-rich Pilbara region. The Pilgangoora Project is one of the biggest new lithium ore (spodumene) deposits in the world, with a globally significant hard rock spodumene resource. 

The Project is accessible by road, with access to existing infrastructure including port facilities at the port of Port Hedland.

The outstanding quality of the Pilgangoora Project has enabled Pilbara Minerals to take it from first drill hole to production in under four years.

Resources and Exploration

Substantial increases in the global resource at the Pilgangoora Project have reinforced its status as Australia's premier lithium development Project. In September 2018, Pilbara Minerals increased the Mineral Resource estimate to 226.0 million tonnes grading 1.27% Li2O (lithia) and 116ppm Ta2O5 (tantalite) and 0.60% Fe2O3. The current Mineral Resource estimate containing 2.86 million tonnes of Li2O (lithia) and 57.7 million pounds of Ta2O5 (tantalite). 

Future drilling will focus on several under-explored target areas within the Pilgangoora Project, many of which have been identified from the occurrence of outcropping spodumene bearing pegmatites. The new targets demonstrate the potential for incredible endowment within the project area and are considered important for further resource growth over the coming years.

In September 2018, Pilbara Minerals increased the Ore Reserve estimate published in June 2017. The expanded Proved and Probable Ore Reserve now stands at 108.2 million tonnes grading 1.25% Li2O (lithia) and 120 ppm Ta2O5 (tantalite) and 1.17% Fe2O3.

A September 2016 Definitive Feasibility Study confirmed a robust, high margin project with a post-tax Net Present Value of A$709 million and a strong Internal Rate of Return of 38.1%.

Based on a proposed 2 million tonne per annum stand-alone mining and processing operation, the DFS forecast current life of mine revenue of A$9.23 billion and life of mine Project EBITDA of A$4.22 billion over an estimated 36-year mine life.

Construction of the Pilgangoora Project commenced in January 2017 and was completed at the end of July 2018.

Pilbara Minerals is currently commissioning and ramping up the Pilgangoora Project to 'name plate' capacity which produced its first 'on spec' concentrate in August 2018.

On 2 October 2018 Pilbara Minerals achieved a major milestone with its first spodumene concentrate product shipment from the Pilgangoora Project. A total of 8,800wmt (wet metric tonnes) of spodumene concentrate grading approximately 6.1% lithia and 1.2% Fe2O3 set sail from Port Hedland port bound for the Company’s offtake partners in north Asia. 

Stage 2, 5Mtpa expansion 

In February 2018, Pilbara Minerals released a Pre-feasibility Study into the expansion of the Pilgangoora Project to a 5Mtpa operation. Following the positive results of this study released on 3 August 2018, Pilbara Minerals commenced the Definitive Feasibility Study (DFS) for the Stage 2, 5Mtpa expansion. The Stage 2, 5Mtpa DFS delivered exceptional results including a post-tax Net Present Value10% of A$2.160B, life of mine project revenue of $A12.2 billion ($ real) and life of mine EBITDA of $A6.3B ($ real), re-affirming the Pilgangoora Project’s scale, quality, competitive forecast cash operating costs, robust operating margins, long life and exceptional economic returns. 

The DFS results, together with the strong support from offtake partners and Pilgangoora Project's scalability, provide a compelling case for the Stage 2 expansion to proceed following recent commissioning of the Stage 1, 2Mtpa facility


The low cost, long life and outstanding quality of the Pilgangoora Project has attracted a group of high quality, experienced global offtake partners including Ganfeng Lithium, General Lithium, Great Wall Motor Company and POSCO. Collectively, these partners underpin the Stage 1 and 2 projected production from the Pilgangoora project.

For Stage 1, Pilbara Minerals has secured a binding offtake agreement with General Lithium, a leading Chinese supplier of lithium products and materials to the fast-growing lithium battery industry in China. This offtake agreement is for the supply of 140,000tpa of 6% chemical-grade spodumene concentrate for a six-year period, with the option to extend for a further four years. This represents over 40% of the Pilgangoora project's anticipated initial annual output of ~330,000tpa of concentrate (inclusive of technical grade spodumene) from Stage 1.

Following this, Pilbara Minerals secured a long-term binding offtake agreement with Ganfeng Lithium, one of China's largest integrated lithium producers. The agreement includes the supply of 160,000 tonnes per annum of chemical-grade spodumene over an initial term of 10-years, with two five-year options to extend up to a further 10-years.

To support the Stage 2, 5Mtpa expansion, Pilbara Minerals has entered into an offtake agreement with Great Wall Motor Company one of China’s largest pickup and sport-utility vehicle manufacturers. This offtake agreement encompasses 75,000tpa of chemical grade spodumene concentrate (SC6.0 basis) with the option for a further 75,000tpa (for a total of 150,000tpa) following agreement of binding terms with respect to a debt or offtake prepayment funding facility for Stage 2 of up to US$50 million.

To complement this already extensive, highly experienced list of global offtake partners Pilbara Minerals has entered into a strategic relationship with POSCO. This relationship encompasses long-term offtake, funding and importantly, the opportunity to participate in a joint venture for a downstream conversion plant in South Korea. The downstream processing opportunity provides Pilbara Minerals a number of advantages including a first-mover position in this fast-growing Korean market. POSCO is one of the largest suppliers of steel to the global automobile industry and has a vision is to become a ‘total solution provider’ for EVs.

The landmark agreements with POSCO encompass a binding life of mine offtake agreement for an initial 80,000tpa of chemical grade spodumene concentrate (SC6.0 basis) from the Stage 2, 5Mtpa operation, increasing up to 240,000tpa upon Pilbara Minerals’ minimum participation of 30% in a downstream joint venture conversion plant in South Korea. 

The ability to manufacture high-value battery-grade lithium products through downstream processing has the potential to deliver significant additional value for Pilbara Minerals in the years ahead, with global demand for lithium ion batteries expected to experience unprecedented growth over the coming decades.
