BANKABLE FEASIBILITY STUDY Post Quarter end, on 12 April 2017, the Company was pleased to report the results of the Bankable Feasibility Study for its 75% owned Ngualla Rare Earth Project. The Study components consist of a mine and multi-stage processing plant on-site at Ngualla in Tanzania and a proposed refinery in Tees Valley in the UK. The BFS is based on detailed engineering studies and extensive pilot planting of the three stage extraction process which was successfully demonstrated using bulk samples of Ngualla’s unique bastnaesite mineralisation. The in depth Study was also guided by real world experience of Peak’s team of rare earth industry mining, processing and marketing specialists in conjunction with global engineering firm Amec Foster Wheeler. The BFS has delivered significant reductions in operating costs and facilitated access to higher value markets as compared to the Company’s project update ASX announcement “Ngualla Project Study delivers substantial Capex and Opex savings” dated 16 March 2016. The results of the BFS confirm that the Ngualla Project has the potential to become one of the lowest cost and highest quality rare earth projects worldwide.

PHYSICALS DRIVE NGUALLA’S FAVOURABLE ECONOMICS Ngualla’s low operating costs and favourable project economics are driven by a unique combination of qualities including the high NdPr grade and advantageous mineralogy of the rare earth deposit itself, together with the development of an extraction and purification process that targets the higher value rare earths whilst rejecting impurities and the majority of lower value cerium. The location of the refinery in proximity to sources of inexpensive bulk reagents and existing utilities is also a key driver of lower Opex. With the alignment of products and value drivers to the high demand magnet metal market the project is in a favourable position in terms of marketing and future demand for its products, which will represent less than 5% of total world demand.

MOUNTAIN PASS Post Quarter end on 26 April, Peak was pleased to announce the Company’s participation in a Consortium that has the aim of acquiring and re-starting the Mountain Pass rare earth operation in California, USA. The Mountain Pass mine, located 80 kilometres south of Las Vegas, Nevada, is the only mine and processing facility for rare earth minerals in the United States. The mine has an operating history dating back to the 1950s and is currently on care and maintenance after the Debtors filed for Chapter 11 bankruptcy protection in 2015. The Company will provide further information in due course when it becomes available.

ORE RESERVE ESTIMATE An updated Ore Reserve estimate was announced simultaneously with the BFS after Quarter end on 12 April 2017. The Ore Reserve estimate for the Ngualla Project is 18.5 million tonnes at 4.80% REO (total rare earth oxide plus ) for 887,000 tonnes contained REO and is classified as shown in Table 2 below:

The Ore Reserve is reported in accordance with the JORC Code 2012, is estimated by Mr. Ryan Locke of independent mining consultancy Orelogy Consulting Pty Ltd, and accompanies the announcement by the Company of the positive Bankable Feasibility Study (BFS) into the development of the Ngualla Project (ASX Announcement “BFS positions Ngualla as one of the world’s lowest cost rare earth projects” of 12 April 2017. Further details of the Material Assumptions and technical parameters underpinning the Ore Reserve estimate are summarised in ASX Announcement “Ngualla Rare Earth Project – Updated Ore Reserve” of 12 April 2017, continue to apply and have not materially changed. The Ore Reserve estimate confirms Ngualla as one of the highest grade NdPr rare earth deposits in the world. In addition to also being one of the world’s largest, the Ore Reserve estimate is high confidence with 91% in the highest Proved JORC 2012 category. The mineralisation style also offers advantages over other rare earth deposits in a number of key areas (see Figure 2).

NdPr prices rise 9% in 2017 After 6 years of decline, NdPr prices had an exceptional start to 2017 with a 9% rise after the largest producer – the Chinese company Northern Rare Earth Group (Baotou) – announced and implemented three consecutive price increases from February 2017 (see Figure 4 on following page). The Company believes that this reversal, together with the widespread projections of increasing demand from the electric, hybrid automobile and green energy industries, combined with China’s internal policies and restrictions

PROJECT PERMITTING - ENVIRONMENTAL CERTIFICATE RECEIVED FOR NGUALLA The Environmental Certificate for the Ngualla Rare Earth Project in Tanzania was granted by the Minister of State of the Vice President’s Office in March 2017 and represents a major step in the permitting of the project. The Environmental Certificate is a pre-requisite for the granting of a mining licence. The Environmental Certificate marks the successful completion of the regulatory Environmental Impact Statement. The two year study that supported the EIS Report was led by Tanzanian environmental consulting specialists Align Environment and Risk and Paulsam Geoengineering Co Ltd. The study included multi-disciplined wet and dry season environmental and social baseline studies and extensive stakeholder consultation as well as a site visit and a review board meeting with the regulators, the National Environment Management Council. Strong support for the development of the Ngualla Rare Earth Project was received at a local village, District, Regional and National level during the stakeholder meetings. The project area has no human habitation, farming, grazing or reserves.

DISCOVERY OF WIDE ZONES OF HIGH GRADE FLUORSPAR AND NEW STYLE OF RARE EARTH MINERALISATION In February 2017 the Company was pleased to report the results of trench sampling within the alteration zone that forms a ring of hills surrounding the Ngualla Carbonatite proper (Figure 5). The trenches were designed to follow-up high grade fluorspar results received from reconnaissance rock sampling in this largely soil covered area.

Fluorspar is an industrial mineral important as a flux in iron and aluminium smelting and also has a range of For personal use only use personal For applications in the chemical industry. It is also known as or calcium fluoride (CaF2). Wide and continuous zones of high grade mineralisation up to 78m at 37% fluorspar were identified by the trenching program within a breccia zone that can be traced for 3.8 kilometres (ASX Announcement “Wide Zones of high grade fluorite identified at Ngualla” of 20 February 2017). Two of the three trenches completed to date are continuously mineralised along their entire length, with the mineralisation remaining open in all directions.

Figure 5: Location of the three trenches and recent rock samples within the alteration zone surrounding the Ngualla Carbonatite in relation to the Bastnaesite Zone rare earth mineralisation. Geological interpretation draped over topography.

Higher grade intervals include 12m at 54% fluorspar in trench NCS010 and 8m at 62% fluorspar in NCS011, with the maximum 2m sample returning a maximum grade of 82% fluorspar. In addition a new zone and geological style of rare earth mineralisation up to 53m at 2.37% rare earth oxide (“REO”) was also identified by the trench sampling. The wide zones of mineralisation confirmed by this initial trenching program, together with the widespread mineralised rock samples returned from reconnaissance work are encouraging. Further work is planned to investigate the potential for a significant and high grade fluorspar deposit at Ngualla, as well as evaluate the potential for additional rare earth mineralisation in this new geological setting.

For personal use only use personal For These first trench sampling results also reinforce the multi commodity endowment of the Ngualla Carbonatite and the potential for future, supplementary value add products once a rare earth operation is established at Ngualla. In addition to the recent fluorspar discovery, additional commodity occurrences confirmed at Ngualla also include , phosphate and barite (see Table 3).

BARITE INCLUDED IN NGUALLA MINERAL RESOURCE ESTIMATE The potential for a barite by-product from Ngualla was identified during BFS work programs through the production of a high grade barite stream during rare earth mineral processing. The Mineral Resource estimate for Ngualla was

therefore re-issued to report the industrial mineral barite (barium sulphate, BaSO4) within the rare earth Mineral Resource, with no change to rare earth estimates (Table 3). The Mineral Resource estimate was updated to include barite by SRK Consulting (Australasia) Pty Ltd to include the reporting of barite as a by-product within the rare earth Mineral Resource estimate at a 1% lower grade cut off REO (see ASX Announcement Ngualla Mineral Resource estimate re-stated to include barite” of 2 March 2017 for further details). There has been no change to the Mineral Resource estimate or assumptions since this report. The Company plans to complete further technical and marketing studies to evaluate this potential future opportunity but barite production is excluded from the current BFS. The Mineral Resource estimate for the Weathered bastnaesite Zone mineralisation at a 1% REO lower grade cut-off is: 21.3 million tonnes at 4.75% REO* and 37.7% barite for 1,010,000 tonnes of contained REO and 8.03 million tonnes of contained barite.

Barite grade is derived from geochemical assays for barium and the assumption, supported by extensive mineralogical studies, that barium is present as barite.

ENGAGEMENT WITH POTENTIAL STRATEGIC PARTNERS During the quarter the Company had further discussions with potential strategic partners evaluating a number of options from direct sale of rare earth concentrate and toll treatment through third party facilities in addition to the base case of the establishment of a Refinery in Tees Valley. Joint technical evaluation of these options is continuing.

NEXT STEPS With the completion of the BFS, the Company is well placed to ramp up discussions with potential debt financers, offtake partners and strategic investors to take the project through the Front End Engineering and Design (“FEED”) stage and beyond. The receipt of the Environmental Certificate for Ngualla this Quarter, together with the completion of the BFS, will allow the Company to progress through the mining licence process as both documents are major requirements for a For personal use only use personal For mining licence application. The multi commodity endowment of the Ngualla Carbonatite demonstrated by the fluorspar discovery and occurrences of barite, phosphate and niobium in addition to rare earths suggests the potential for supplementary value add commodities to be produced from Ngualla, especially once on site infrastructure and an access road have been established for the rare earth operation. The Company will continue to assess the economic potential of these other commodities in addition to the main focus of rare earths. With the Ngualla Camp set to re-open after the rains in early May, field programs and sampling will continue to evaluate the new fluorspar and rare earth discoveries.
