Muga Potash Project
Overview
Highfield Resources (ASX: HFR) (“Highfield” or “the Company”) is a Spanish potash developer. The Company’s flagship Muga Potash Project (“Muga” or “the Project”) is targeting the relatively shallow sylvinite beds in the Muga Project area that cover about 80km[2] in the Provinces of Navarra and Aragon. Mineralisation commences at depths from surface of less than 200 metres and is ideal for a relatively low-cost conventional mine accessed via a dual decline, as demonstrated in the Company’s Muga Project Optimisation Study completed in November 2015 (refer to ASX announcement dated 17 November 2015).
Permitting Update
On 1 May 2017, the Company announced (refer ASX release “Formal Responses to Government on Muga Potash Project Submitted”) that it had submitted its revised environmental document to the Ministry of Agriculture, Fishing, Food and Environment (“MAPAMA”). The submission document, which included answers to all technical queries raised by the referral authorities and MAPAMA, as well as additional technical work completed by the Company, was compiled with the assistance of Highfield’s Spanish consultants, TYPSA. TYPSA has successfully managed over 200 Environmental Impact Assessments and Declaración de Impacto Ambiental (“DIA”) processes.
MAPAMA requested clarification and reconsideration on several components of the Project. The Company liaised extensively with the referral authorities on each item to ensure that all comments were addressed and, where possible, incorporated into the Project. The engagement with the referral authorities was positive and indicates there is a strong resolve for the Project to move forward amongst these local and regional bodies.
Following the end of the quarter, the Company announced that it would pursue a public exposition period for its recently submitted environmental documentation, commencing on 1 September 2017. Whilst there is no legislative requirement for this process, Highfield believes it is important to allow stakeholders of the Project the opportunity to make final comments before the award of the DIA.
Muga Mine Development Progress
Detailed engineering work slowed during the June quarter as the Company reached logical points to hold work ahead of the receipt of permits for Muga. Nonetheless, Bovis Project Management S.A, one of the leading local specialist project and construction management companies, has been appointed to assist in a project cost and schedule review and progress the construction contract packaging strategy in anticipation of the receipt of permits.
Work continues with consultants in a number of areas to optimise and fine tune the Project. Specifically, SRK is now providing ongoing mining support as well as preparing a mining tender package document. In addition, a process consultant with extensive potash experience has been appointed to advise and support the Geoalcali team and a tender process for the appointment of a sustainability consultant to undertake a gap analysis is also underway.
During the quarter, Highfield completed a drill hole to provide geotechnical information at the foot of the western decline which was drilled through to the footwall salt horizon. The drill hole was located in an area which was expected to be characterised by a thinning of mineralisation due to an anticline structure. In fact, the drill hole intersected over 6 metres of potash mineralisation from 502 metres below surface, with an average grade of 7.32% K2O. Within the PB seam, which is the primary mining horizon at Muga, drilling encountered 2.7 metres with an average grade of 10.46% K2O including 1.5 metres with an average grade of 14.82%. This result was better than expected, from both a grade and thickness

perspective. Mineralisation was predominantly brecciated in texture. A detailed summary of drill hole R- 03 can be found in Table 2.
Highfield continues to progress the revised Feasibility Study to include new information, further optimisations and to provide updated capital cost estimates for the Project.
Project Financing
During the quarter, the Company continued its dialogue with its Project Finance syndicate with respect to the €185 million facility for Muga. It also engaged with other potential providers of capital.
Highfield remains confident of putting in place its debt financing following receipt of all approvals, to support a final investment decision and the commencement of construction.
Pintanos Potash Project
Highfield´s 100%-owned Pintanos Project (see Figure 1) abuts the Muga Project and covers an area of 60km[2] . Depths from surface to mineralisation commence at around 500 metres. The Company is building on substantial historical potash exploration information which includes seven drill holes and ten seismic profiles completed in the late 1980s.
During the quarter, limited additional work was carried out.
Sierra del Perdón
Highfield´s 100%-owned Sierra del Perdón (“SdP”) Project (see Figure 1) is located south east of Pamplona and covers approximately 145km[2] . SdP is a brownfields project with two potash mines operating from the 1960s through until the late 1990s producing nearly 500,000 tonnes of K60 MOP per annum. The Company completed a Scoping Study on SdP (refer ASX announcement 20 April 2015) which confirmed the technical and economic viability of the project.
During the period, the Company completed drill hole SDP-008 at SdP. Despite challenging conditions, which slowed the progress of the drilling, it intercepted the various lithologies, including the carnallite and sylvinite seams, at the expected levels. In particular, the results from the sylvinite seam were positive with broad zones of potash mineralisation encountered from approximately 776 metres to approximately 785 metres below surface. The sylvinite horizon intersected 3.6 metres of potash at an average grade of 15.68% K2O including 1.8 metres at an average grade of 22.42% K2O. This drilling is within close proximity to the former operating mine owned by Potasas de Subiza, which produced for nearly 30 years, closing in 1996.
A summary of the assay results can be seen in Table 3.
The Company plans to commence an additional exploration drill hole at Sierra del Perdón in the coming months.
Vipasca
Highfield´s 100%-owned Vipasca Project (“Vipasca”) is located adjacent to the Muga Project and covers approximately 120km[2] . The tenement is highly prospective for economic potash mineralisation, with primary focus on the deeper, higher grade, P1 and P2 potash horizons.
The Company is currently undertaking an exploration drill hole at Vipasca. Results are expected in the coming months. In addition, Highfield has planned an extensive geophysical (TDEM) program to complement the drill program.

Other Projects
The Company has an additional 100%-owned project in the basin (see Figure 1) known as Izaga. Limited work was carried out on this project during the quarter.
Corporate
A recent initiative has been the appointment of Spanish advisors to both Highfield and its local subsidiary, Geoalcali. These individuals are respected Spanish nationals who are able to provide insight to the Company as it seeks to cement Muga as a worthy and sustainable enterprise in the Navarra and Aragon Provinces of Spain. Mr Sixto Jimenez is a well-known business person in Navarra with international experience who remains very active in the business and community circles of Pamplona and continues to be a significant social commentator. Mr Isaac Querub is an internationally experienced and recognised business person who has held executive roles in the minerals industry including a senior position in Glencore. Both these individuals are anticipated to contribute significantly to the Company’s long term sustainable success in Spain.
Cash Position
As at 30 June 2017, the Company had A$69.6 million in cash on its balance sheet.

Highfield’s Muga, Vipasca, Pintanos, Izaga and Sierra del Perdón potash projects are located in the Ebro potash producing basin in Northern Spain, covering a project area of more than 550km[2] . The Sierra del Perdón project includes two former operating potash mines.
The Company completed a Definitive Feasibility Study for its flagship Muga Project in March 2015, which was optimised in November 2015 to enhance operational efficiencies, sales and marketing activities and the life of mine. Highfield is awaiting a positive environmental declaration which will enable it to commence construction of the Mine.
In addition to the existing Muga Project, Highfield also has significant Exploration Targets for an extension to Muga, as well as for the Vipasca and Pintanos Potash Projects.
