MAIDEN RESOURCE,
NGUALLA RARE EARTH PROJECT
Peak Resources Limited (Peak) is pleased to report a Maiden Mineral Resource estimate reported according
to the 2004 JORC Code and Guidelines, for the Ngualla Rare Earth Project in southern Tanzania.
Richard Beazley Managing Director of Peak Resources (ASX: PEK) stated, “What makes this discovery very attractive is the
significant grades that make Ngualla stand apart from most rare earth deposits. Having these high tonnages and grades places
Ngualla amongst the top rare earth resources outside of China.
The time frame from discovery to resource has been outstanding particularly in consideration of the sheer size of the deposit that
has been delineated into resource status.”
Highlights:
• The Mineral Resource Estimates at a 1.0% lower grade cut-off for the combined
Southern Rare Earth and South West Alluvial Zones is:
170 million tonnes at 2.24% REO*, for 3.8 million tonnes of contained REO.
• Using a 3.0% lower grade cut, the total resource includes a higher grade near surface zone of:
40 million tonnes at 4.07% REO for 1.6 million tonnes of contained REO.
• The maiden resource combined with encouragement from early metallurgical test work and
proposed new drilling will allow the Company to commence scoping studies next quarter.
• This is a major milestone for Peak and takes the Company from an explorer to a developer.
*REO= total rare earth oxides plus Y2O3
Richard Beazley commented further, “This resource puts Peak in a dominant position from which to develop the asset into an
operating mine with its strengths defined to date by the significant tonnes and grade, very low thorium and uranium levels and
outcropping bulk style geometry centred around a hill lending itself for very low strip ratios in mining.
The next step in the development of Ngualla will be for a very busy year ahead for the Peak team. The 2012 drilling program
will focus on infill drilling primarily in the Southern Rare Earth Zone to move more of the resource into Measured and Indicated
categories to assist in mine planning and financial requirements. Drilling will also focus on testing the resource where it currently
remains open to the north, south and with depth.
Additionally, metallurgical test work will continue and further bulk material is scheduled to be supplied from additional diamond
drilling to support the ongoing metallurgical program later in the year.
Peak will also be moving forward with a scoping study to integrate the current defined maiden resource and metallurgical
understanding with other key aspects such as marketing, logistics, supply and mining to assess the economic potential of
numerous development pathways for the project over the coming year.
With the recent purchase of Zari behind us and 100% ownership in the bag, the future for Peak is very exciting indeed.”
Technical Report
Peak has moved the Ngualla Rare Earth Project forward rapidly over the last 18 months from discovery in August 2010 to
today’s release of the maiden Mineral Resource Estimate.
The Mineral Resource is based on three phases of drilling comprising over 26,700m of drilling in 651 drill holes. The last phase
of drilling was completed on 30th November 2011 and results received in mid February 2012.
The resource estimate reported according to the JORC Code and Guidelines was completed by independent resource
consultants Hellman and Schofield Pty Ltd for the Southern Rare Earth and South West Alluvial Zones (Figure 1).
Block grades in a 20m x 20m x 5m block model were assigned using Ordinary Kriging geostatistical techniques from two metre
sample composites with searches aligned parallel to the strike and dip of the mineralisation. Density measurements collected
from 9 diamond core holes located in or surrounding the main mineralised zones and applied to the entire project area on the
basis of rock type. Further modelling parameters are detailed in the ‘Notes on Resource Estimation’ at the rear of this report.
A section through the block model in the Southern Rare Earth Zone is shown in Figure 2.
The Mineral Resource estimate for the Southern Rare Earth and South West Alluvial Zones at Ngualla above a 1% REO cut-off is:
170 million tonnes at 2.24% REO, for a total of 3.8 million tonnes of REO
(See Table 1 for classification details)
The distribution of individual rare earths plus yttrium oxides that make up the total for the 1% cut is shown in Table 4.
The mineralisation at Ngualla is of three main types: 1) surface iron rich gravel deposits, 2) iron rich, strongly weathered
carbonatite and 3) fresh rock carbonatite. The 170Mt Mineral Resource includes a higher grade near surface portion of
mineralisation. Above a 3% REO cut-off grade this is:
40 million tonnes at 4.07% REO, for a total of 1.6 million tonnes of REO.
(See Table 1 for classification details)
The majority of this mineralisation consists of near surface, ferruginous weathered carbonatite.
The Ngualla rare earth deposit can be divided into two geographic and geological areas, the Southern Rare Earth Zone
located in the centre of the carbonatite around Ngualla Hill, and the South West Alluvial Zone (see Figure 1). The resource
and geology for each zone differs and hence is described individually below:
Southern Rare Earth Zone: A 1km x 1km area in the low magnetic central core of the Ngualla Carbonatite (Figure 1). Rare
earth mineralisation occurs from surface and is enriched in the weathered zone of the carbonatite, varying from a few metres
to 140m vertical depth. Fresh rock mineralisation extends to the current drill depth of 155m from surface.
Mineralisation in the Southern Rare Earth Zone (SREZ) remains open to the north, south and with depth with a high likelihood
that further drilling would increase the size of the deposit.
The bulk of the Mineral Resource at Ngualla is contained within the SREZ and most of the highest grade component occurs
near surface within the weathered zone (see Figure 3). Table 2 shows the classification of the Mineral Resource for the SREZ
at cut-off grades of 1% and 3% REO.
South West Alluvial Zone: Located to the south west of Ngualla Hill (see Figure 1). Rare earth mineralisation occurs from
surface within unconsolidated ferruginous gravels to depths of up to 30m. Rare earth mineralisation in the South West Alluvial
Zone is the result of erosion, transportation and deposition of weathered bed rock mineralisation in the Southern Rare Earth
Zone.
The average REO % distribution for each of the two Mineral Resource zones is shown in Table 4.
Project Status
The Ngualla rare earth mineralisation is shallow and could easily be exploited by open cut methods. Early metallurgical test
work managed by consultants Bateman Engineering Ltd has returned encouraging results (ASX report: 31st January 2012;
‘Early encouragement from preliminary metallurgical test work – Ngualla Rare Earth Project’):
• Higher grade, near surface oxide mineralisation may be amenable to conventional acid leach - a relatively simple processing
route to a high grade rare earth concentrate.
• Simple wet table characterisation of primary fresh rock rare earth mineralisation produces positive beneficiation results in
preliminary sighter tests. Work is now underway to determine if standard flotation for bastnasite as a subsequent processing
step has the potential to produce a saleable rare earth concentrate.
• The extremely low levels of uranium and thorium present in the Southern Rare Earth Zone (21ppm U and 35ppm Th) is a
distinct advantage to the Ngualla Project over other rare earth projects.
The resource estimation and block model, combined with the completion of this early stage metallurgical test work will allow
scoping studies to commence to begin to quantify the economic significance of this large new rare earth discovery. Preparations
are underway for an infill drilling program to commence at Ngualla after the rains end in May 2012. The drilling will provide the
necessary higher density of data to support an upgrade to Measured Resource category and also seek to extend the resource
in several directions where it currently remains open.
Richard Beazley stated, “the publication of this significant resource statement for an outcropping, bulk deposit, with very
low thorium and uranium levels and encouraging initial metallurgical test work is indicating the potential for Peak to position
themselves as a low cost rare earth producer with a long term presence in the rare earth industry.”
