Maiden JORC Ore Reserves - Khnaiguiyah Zinc-Copper Project

Perth: Australian-based minerals exploration and development company Alara Resources Limited (ASX: AUQ) ( Alara ) is pleased to provide maiden JORC Ore Reserves for the Khnaiguiyah Zinc-Copper Project (the Project ) located in Saudi Arabia of:

  • Proven Ore Reserves of 17.7 Mt at 3.4% Zinc and 0.29% Copper

  • Probable Ore Reserves 8.4 Mt at 3.1% Zn and 0.13% Copper

The Khnaiguiyah Project entails the development and excavation of three open pit mines within a radius of 2 km and a central 2 Mtpa processing facility to produce both zinc and copper concentrates for export to overseas smelters and ultimately for Saudi domestic smelters.

The project schedule contemplates mining the entire orebody over 9.5 years with a further 4 years processing of residual long-term stockpiles.

The average grade of the feed to the process plant for the first 7 years is expected to be 4.36% Zinc and in the first 9.5 years approximately 3.95% Zinc. Low grade stockpiles are proposed to be processed thereafter.

Commenting on the maiden Reserve Statement, Managing Director, Shanker Madan said:

“We now have confirmed JORC Ore Reserves for the Khnaiguiyah Zinc – Copper Project. These Reserves underpin a 13 year Life of Mine. The Khnaiguiyah Project area has considerable upside and with a completed DFS which justify the economics of this Project, the results of which will follow shortly, future generations will see this as a historic moment in the life of the Khnaiguiyah Project”.

Introduction

The Khnaiguiyah Zinc-Copper Project is located approximately 170 km south-west of the capital city Riyadh and just north of the village of Al-Khnaiguiyah in the Kingdom of Saudi Arabia ( refer Figure 1 ). The nearest regional centre is Al-Quwayiyah, located on the Riyadh to Jeddah Expressway some 35 km from the site.

The Project will be operated by the Khnaiguiyah Mining Company LLC ( KMC ) which is a 50/50 joint venture between Alara Resources Limited and United Arabian Mining Company LLC ( Manajem ), a privately owned Saudi Arabian mining company. The joint venture was formed in October 20101 for the purpose of exploring and developing the Khnaiguiyah mineral zones within the mining licence area and a number of surrounding mineral licences.

JORC Mineral Resource Statement

The Khnaiguiyah Project comprises four ore bodies/mineralised zones located within 1 to 2 km from a central area and approximately 3 km from each other ( refer Figures 3 and 4 ).

In October 2012[3] , Alara updated the maiden[4] Mineral Resource Statement for the Khnaiguiyah Project.

The Mineral Resource Statement was reported in terms of mineralogical domains that reflect different metallurgical regime requirements:

  • “Domain 1” - has Zinc but no Copper;

  • “Domain 2” - has Zinc and Copper; and

  • “Domain 3” - has Copper but no Zinc.

The upgraded October 2012 Mineral Resource Statement formed the basis for this Ore Reserve Statement and is summarised in Tables 1, 2 and 3.

JORC Ore Reserve Statement

The Ore Reserves were determined using the Net Smelter Return ( NSR ) method to generate an economic cut-off. This method was considered to provide the best representation of value contained within the Mineral Resources. The NSR cut-off was estimated on a mine gate sale basis and accounts for pricing assumptions, process plant recovery, transport costs, TC/RC and smelter deductions.

The Ore Reserves were estimated from within practical mining shapes designed from economic mining envelopes produced from Whittle pit optimisation software. Only regions within the Mineral Resource that were classified as Measured or Indicated and were above the NSR cut-off were included.

From the mine plan estimated an Ore Reserve of 26 Mt of Proved and Probable ore was estimated at an average grade of 3.3% Zn and 0.24 % Cu. No downgrading of classification was applied. The Ore Reserve estimate is summarised in Table 4 and the Ore Reserve parameters are outlined in Table 5.

Mining Method

This Ore Reserve Statement contemplates conventional open pit mining methods. The pits will be mined using drill, blast, load and haul techniques. Rock will be mined from the pit using a combination of 5 and 10 m high benches. Backhoe style excavators will be used to load blasted rock onto off-highway dump trucks. The ore will then be trucked to surface stockpiles for processing. The host rock will be stockpiled on surface, together with filtered tailings in a co-disposal facility. Both the K2 and K3 pits will be mined using multiple stages to maximise early cash flow for the Project.

The project schedule contemplates mining over 9.5 years with a further 4 years processing of residual long term stockpiles. The ore mining and processing schedule is given in Figure 5.

Processing

The crushing and grinding circuit was based on comminution data from metallurgical testing comminution parameters derived from master and variability composites. The process plant flow sheet was developed from metallurgical test work and validated through locked cycle flotation testing.

The plant will have a name plate capacity of 2 Mtpa and comprise of single stage primary jaw crusher feeding a coarse ore stockpile. The stockpile will feed a comminution circuit comprising a SAG and ball mill and pebble crusher.

A two stage differential float circuit, equipped with regrind mills, will recover copper then zinc concentrates from the process streams. Thickeners will be used to dewater all products, including tailings with further dewatering occurring during the dewatering stage. The copper and zinc concentrates will pass through respective plate filters before being discharged into the concentrate storage shed. Tailings will be passed over a belt filter then conveyed to a stockpile for transport to the co-disposal facility landform.

The concentrates will be loaded into covered half-height-containers before being transported to the port of Dammam. At the port, the concentrate will be unloaded inside the hold of bulk carrier ships for transport to various overseas smelters. Annual concentrate production is estimated to be around 180,000 wmt (wet metric tonnes) per year for the first five years.

Pre-production Capital Costs

Total preproduction capital is estimated to be US$257 million including all mining, processing and surface infrastructure and working capital. The project capital development cost to the commencement of production assuming a plus or minus 15% order of accuracy variation is given below in Table .

Operating Costs

Project operating costs were derived from detailed bottom up estimates based on mining and processing being carried out by KMC. Operating cost estimates were compiled using vendor quotations for key cost items. Labour costs were based on rates determined by market research of local, expat and third country nationals. Mining costs were compiled by IQE Pty Ltd and processing and administration costs were compiled by Ausenco Services Pty Ltd during the 1.5mtpa ECS and upgraded by Megabest Pty Ltd and IQE Pty Ltd to represent the revised 2.0mtpa throughput.

Table 5: Estimation and Reporting of Khnaiguiyah JORC Ore Reserve Statement

Criteria Explanation
Mineral Resource
estimate for
conversion to Ore
Reserves

Mineral Resource estimates were created using Ordinary Kriging for K1 and K2 mineral
deposits and Uniform Conditioning was conducted on K3. Variography was completed on
Cu and Zn. Density was estimated by wet methods at ALS Laboratory in Jeddah.

The Mineral Resource reported is inclusive of the Ore Reserves.

The Mineral Resource estimate was completed in October 2012 for K1 and K2 and July
2012 for K3.
Study status
This Ore Reserve was based on designs and estimates consistent with a detailed
feasibility study. The capital and operating costs were largely based on Vendor estimates
specific to the project and are considered to be within +/- 15% order of accuracy. Where
costs were not available costs were taken for recent pricing from within the consultants
cost data sources.

A detailed mine plan was developed from which a practical mining schedule was
determined. Standard modifying factors associated with the selected mining method have
been applied. The mining method will use conventional open pit mining techniques to
recover detailed economic mineralisation. A variety of studies were undertaken consistent
with a detailed feasibility. Some of the key studies included geotechnical analysis, mine
design and scheduling ore and waste removal, metallurgical testing, process design and
transportation.
Cut-off parameters
The Net Smelter Return (NSR) method was used to determine the economic cut-off for
the mineralisation. The NSR values were estimated on a ‘mine gate’ sale basis and
incorporated real metal price forecast estimates for year 2015 and onwards by market
analysis firm CRU. The NSR value was adjusted for transport costs, port handling
charges and TC/RC on all payable metals. Payable metals include copper and zinc.

The incremental cut off was determined from the site operating costs including extra cost
of ore mining, processing cost and site administration and overhead costs. The cut-off
was estimated for three mineralogical domains being; D1 producing zinc concentrate
only, D2 producing both zinc and copper concentrate and D3 producing copper
concentrate only. The cut-off values were estimated to be to be US$17.24 per tonne for
D1, US$17.87 per tonne for D2 and US$16.29 per tonne for D3.

Mining factors or
assumptions

The Ore Reserve was determined by reporting diluted economic zone within the mining
envelope of each pit. Dilution for K1 and K2 was estimated through reblocking the
mineral resource model to a regular SMU size of 3.75 m x 3.75 m x 2.5 m. Dilution for K3
was determined during the resource estimation process owing to the use of uniform
conditioning approach adopted. These methods considered both dilution of adjacent
mineralisation and ore loss through dilution below the incremental cut off value. In
addition a 2% ore loss was applied to account for operational losses.

The mining method used to determine the Ore Reserve was conventional open pit mining
using 90t backhoe style excavator for ore mining and 160t backhoe style excavator for
waste mining. All rock (ore and waste) will be drilled and blasted then removed to surface
using 90t off-highway dump trucks. Ore will be tipped at the run-of-mine stockpile or low
grade long term stockpile. Waste will be tipped into a co-disposal facility where it will be
combined with thickened tailings from the process plant.

The mining schedule was designed to supply the process plant with a minimum of 2 Mtpa
of ore. Higher rates of ore mining were targeted early in the project life to access high
value ore as soon as possible. The mining schedule includes a pre strip of approximately
8 Mt.

Geotechnical analysis was conducted by George Orr and Associates Pty Ltd. This
analysis was considered appropriate for a detailed feasibility study and included data
collection from borehole logging and orientation measurements, unconfined compressive
strength and elastic modulus testing, mapping of proximal rock outcrops and road
cuttings and interpretation of earlier geological, geotechnical and hydro geological
reports. Interpretation of geological structures and failure mechanisms were made and
stability analysis conducted leading to recommendations of pit slope design parameters.
These parameters were used for Whittle pit optimisation and subsequent detailed mine
design.

The economic mining envelope was determined using Whittle pit optimisation software
and an average cost of mining $1.51 per tonne of rock plus $0.01 per tonne per 10 m of
depth below a nominal surface reduced level. Commercial parameters are discussed
under market assessment below.

A minimum mining width of 30 m was applied to pit floors and 50 m applied to pit stages.

Support infrastructure for the mining operation will be typical for the size and number of
mine equipment. It will include mine workshop and refuelling station, mine offices and
magazine facilities.
Metallurgical factors
or assumptions

The metallurgical process will use differential flotation to produce separate concentrates
of copper and zinc. The method is commonly used throughout the world for the style of
mineralisation that exists at Khnaiguiyah.

The metallurgical process contemplated at the mine utilises conventional technology
which is common practice throughout the world.

Numerous composite samples have undergone batch kinetic testing. The samples were
from each of the deposits. Algorithms were developed for the mineralisation domains.
The recoveries therefore vary depending on the grade of minerals. The average
recoveries across the life of mine were estimated from the project cash flow being as
follows:

Life of mine recovery of Zinc to zinc concentrate = 89%

Life of mine recovery of Copper to copper concentrate = 80%

No provision was made in the NSR estimate for penalty elements. The penalty element
assays are generally below penalty thresholds and, where slightly high, remain in the
negotiable range for settlement.

Locked cycle flotation testing was conducted on a range of composited samples
considered to be representative of the various types of mineralisation. This approach is
considered appropriate for the level of confidence required for a detailed feasibility study.
No bulk samples or pilot scale testing was carried out.

Cost and revenue
factors

Project capital and operating costs were estimated on a bottom-up basis using take-offs
from detailed design. Project specific budget quotations were sourced from vendors in
compiling the estimate. Plant and infrastructure is considered to be estimated to within +/-
15% or better level of accuracy.

The mine head grade was determined from the mining schedule which reported individual
pit production by mineralogical domain and accounted for their specific timing on the
project. The metal prices used were based on real price forecasts by metal traders CRU
for 2015.

Typical off take terms commensurate with prices for copper and zinc concentrates were
used.

Royalties are not payable in the Kingdom of Saudi Arabia.

All costs and revenues were estimated in USD. A conversion factor of 1USD to 3.75SAR
was applied to any prices quoted in local currency.
Market assessment
Metal prices used in the cash flow model were as follows:

Copper US$7,070 per tonne of copper metal

Zinc US$2,335 per tonne of zinc metal

The prices used for the cash flow model were applied as flat forward real pricing and
were based on real price forecast for 2015 by CRU at June 2012. The cash flow was
modelled in real terms and no price or cost escalation was applied.
Other
The Khnaiguiyah Project will be operated by Khnaiguiyah Mining Company LLC (‘KMC’) a
50/50 joint venture between Alara Resources Limited (‘Alara’) (ASX: AUQ) a company
listed on the Australian Securities Exchanges and United Arabian Mining Company LLC
(‘Manajem’), a privately owned Saudi Arabian mining company

The Khnaiguiyah Project is located partially within a granted Mining Licence area (ML
No.2 Qaaf dated 6/1/1432 H) currently held by Manajem with remaining portions located
on Exploration Licence Application Umm Al Wibran and Exploration Licence Application
Khnaiguiyah South. Both Exploration Licence Applications have been lodged by
Manajem with the Ministry of Petroleum & Mineral Resources and carry with them
exclusive rights to the application areas. There are no known impediments to the granting
of these applications or their transfer to KMC.

Under the KMC Shareholders Agreement, Manajem is required to transfer both Mining
Licence and, once granted, the Exploration Licences referred to above, to KMC in
addition to various other Exploration Licences set out in the Shareholders Agreement.

The Mining Licence area will need to be expanded to take in the entire project area.
There are no known impediments to the granting of these.

Further to the Shareholders Agreement, a Mining Rights Agreement executed by Alara,
KMC and Manajem (dated: 2 March 2011) entitles KMC to conduct its business and
exploit the project including the right to mine, market, sell and receive the full proceeds of
sale of any zinc, copper, gold or silver ore or concentrated ore or other product extracted
from the project as though KMC held the Mining Licence and Exploration leases referred
to above.

Approvals Granted to Manajem: Mining Licence (ML), Environmental Licence, Water
Pipeline Route, Undefined Quantities of Water for Mining Village, Industrial Investment
Licence and Commercial Registration (annual renewal required).

Approvals Pending: Exploration Licence Applications, Expansion of ML, Industrial Water
Extraction Rights

Approvals Not Yet Applied: Environmental Certificate (Ports), Export Licence, Explosives
Permits.

The environmental approval requires amendment for consideration of a co-disposal
landform rather than the approved waste dump and tailings storage facility and the
inclusion of the K1 pit.

The mining operations will come within close proximity to the Khnaiguiyah Village which
has a population of approximately 300 people. Mining operations will come within 400 m
of the nearest resident. Social and environmental impact assessments have been
conducted by SMEC and have been deemed to be manageable. The project will require
the relocation of two residents.

A borefield for the supply of process and service water has been identified. Preliminary
analysis has determined that there are reasonable expectations that the borefield will be
capable of supplying the projects water needs however; confirmatory pump tests are still
to be conducted and the impact on proximal users still to be assessed including any
compensation costs.

Classification.
The Ore Reserve was classified in accordance with the JORC (2004) code. Standard
modifying factors and conversions were applied as described above. No known issues
existed at the time which required the levels of confidence of the Ore Reserve to be
downgraded.

The methods used are considered by the Competent Person to be appropriate for the
style and nature of the deposit.
Audits or reviews.
The Ore Reserve estimate has been subject to internal reviews including a project risk
review conducted by key contributors to the feasibility study. No material residual risks
were identified in this review following the implementation of mitigation measures.
Discussion of
relative
accuracy/confidence.

A detailed cash flow model was created using the design case commodity pricing
described above. The cash flow analysis demonstrated a positive return for the project.

Various sensitivity analyses were carried out on the cash flow model. Key parameters
were varied by 15% each way. These parameters included metal prices, foreign
exchange rate, capital cost, operating costs, grade and process recovery. The results
were evaluated on the basis of pre-tax operating cash flow less capital.
