The mine will produce one million tonnes of muriate of potash (MOP) comprising a mix of granular and standard K60 MOP, as well as producing one million tonnes of salt per year as a by-product.
Phase one of production will be for 500,000 tonnes of MOP with an additional 500,000 tonnes for the second phase.
Muga will have access to excellent existing infrastructure with product able to be trucked directly to customers in France and Spain – a competitive cost advantage considering there are no European import duties to other EU countries.
The project is also well-positioned to cater for the Brazilian market, with low freight costs providing a logistical advantage over other MOP producers.
Strong potash demand
Global potash demand increased 25% from 2012 to 2019, however, global production was cut by 2 million tonnes in 2019 due to increased stock levels.
This provides an opportunity in Europe for Highfield, especially considering that the Boulby potash mine in the UK, which had annual capacity of 500,000 tonnes, shut down, as did the Sigmundshall mine in Germany, which had annual capacity of 600,000 tonnes.
Additionally, the Wintershall mine in Germany has restricted production due to low river levels.
This has tightened local supply and high-cost local producers have maintained the European price premium on potash, even during the temporary COVID-19 disruption.
Given Muga’s location, the company expects a large part of the regional premium will be captured at the mine.
It is also well positioned to cater for the forecast 2.5% per annum increase in potash demand globally, reflecting the increased need for higher crop yields and fertilisers as arable land per person decreases and the population increases.
Salt by-product advantages
The demand for salt, which is produced as a by-product of processing potash, is also forecast to grow with the world’s population expected to rise to 9.7 billion by 2050.
Global demand is expected to increase to 424 million tonnes in 2028, from 352 million tonnes in 2018, which is equivalent to a growth rate of 1.9% per year as populations increase and industrialisation in developing countries drives growth in the food industry.
The sale of the salt will also have economic benefits for the Muga Project financials and will help maintain a low environmental footprint by ensuring full compliance with environmental conditions – specifically the removal of all salt from surface as part of the mine’s rehabilitation post-potash production.
In September last year, Highfield signed a non-binding memorandum of understanding (MOU) with Ameropa AG, a Swiss-based agri-business, for the sale of 250,000 tonnes (with the option to increase to 300,000 tonnes) of MOP from Muga.
The company also signed a non-binding MOU in February of this year with Keytrade AG for the sale of 300,000 tonnes of MOP.
Highfield believes that these future potential partnerships will provide an enhanced understanding of the MOP market and logistical expertise that will be invaluable in the first years of production.
Additionally, in April, Highfield signed a non-binding MOU for the sale of up to 500,000 tonnes of salt per annum.
The agreement is between Pardira Premium SL, trading as Maxisalt, and Highfield's wholly-owned Spanish subsidiary Geocali SLU, and comprises 400,000 tonnes of vacuum salt and 100,000 tonnes of de-icing salt.
The company has already signed three non-binding MOUs
Highfield is confident that Muga will potentially be one of the highest margin potash mines globally.
The project's NPV8 is €1.97 billion, it has a 25% internal rate of return, and an EBITDA of €310 million per annum at full production.
Projected phase one capex is €368 million, phase 2 capex is €208 million and C1 cash costs are €82/tonne, including salt by-product credit.
With cash of A$38.8 million (as of March 31) and debt credit of €185 million previously approved by key European banks, Highfield is confident several financing options are available through debt and equity.
Progressing on schedule
Despite the impacts of COVID-19, the timeline to construction for the Muga project remains unchanged with the Spanish Government starting a progressive, four-phase relaxation of confinement rules.
Design and engineering of the process plant is progressing, mining concession documentation has been submitted and construction permits documentation are well advanced.
Construction is estimated to begin 12-18 months after environmental approval is received and is expected to take two years to complete.
In the meantime, the company is progressing with drilling at the Vipasca permit area within the project and has updated the ore reserve estimate for Muga to 108.7 million tonnes of proved and probable reserves at 10.2% potassium oxide, with 27 years life of mine.
