MARKET ANNOUNCEMENT
Drilling Update - Khnaiguiyah Zinc-Copper Project
Alara Resources Limited (ASX: AUQ) refers to its announcement dated 29 July 2011 providing an update of assay results from recently completed drill-holes in Zone 2 of the Khnaiguiyah Zinc-Copper Project in Saudi Arabia (the Project ).
The Company is now pleased to provide assay results from six recently completed drill-holes in Zone 3, together with an update on metallurgical test work undertaken as part of the Project’s Definitive Feasibility Study ( DFS ). The DFS is targeted for completion in Q1 2012.
HIGHLIGHTS
-
Assay results from recently completed drill-holes in Zone 3 continue to correlate with historic holes, confirming historically reported high grade zinc-copper mineralisation:
-
K3DD11_039 : 84 m @ 13.3 % Zn and 0.39 % Cu from 71m, including 19m @ 30.39 % Zn and 0.95 % Cu
-
K3DD11_032 : 65m @ 9.86% Zn and 1.24% Cu from 122m, including 12m @ 15.31 % Zn and 3.09 % Cu
-
K3DD11_035 : 35m @ 7.65 % Zn and 0.18 % Cu from 84m, including 3m @ 38.6 % Zn and 0.87 % Cu and, 21m @ 7.03 % Zn and 0.16 % Cu from 125m, including 1m @ 44.4 % Zn and 0.78 % Cu
-
K3DD11_030 : 54m @ 8.33% Zn and 0.39% Cu from 82m, including 9m @ 20.19 % Zn and 1.52 % Cu and, 13m @ 7.39% Zn and 1.27% Cu from 168m, Including 6m @ 2.06 % Cu
-
K3DD11_022 : 7m @ 5.45% Zn and 0.22% Cu from 107m, and, 21m @ 2.32% Cu from 132m
-
K3DD11_031 : 9m @ 8.68% Zn and 0.47% Cu from 155m, including 6m @ 11.75 % Zn and 0.59 % Cu
-
Metallurgical testwork on Zone 2 samples indicates potential for zinc and copper recoveries in excess of 90%.

20110905 AUQ ASX Drilling Update - Khnaiguiyah Zinc Copper Project
DRILLING PROGRAMME
The drilling programme at the Khnaiguiyah Project, which commenced at the end of February, is continuing with 5 drilling rigs comprising 4 core drilling rigs and 1 reverse circulation (RC) rig. A second RC rig is proposed to be mobilised in September.
A total of 82 holes for approximately 11,473m have been completed to date. Contracts for a total 35,000m of drilling have been awarded.
With all planned PQ metallurgical test holes, mineralisation validation holes and the geotechnical holes completed, the focus of drilling is now on the extension of mineralisation as well as sterilisation of the proposed plant and tailings dam areas.
Drill core samples are being submitted to the ALS Laboratory in Jeddah, Saudi Arabia for sample preparation and Alara’s quality control sample inserts. After quality control inserts, pulp samples are dispatched to an ALS hub in Europe for assay.
There are currently more than 700 samples in the ALS Laboratories awaiting analysis. As results of these samples are received, collated and analysed, the Company will continue to provide regular updates to the market.
DRILLING RESULTS
Five of the six holes reported in this announcement were drilled to verify high grade zinc-copper mineralisation in historic BRGM and Ma’aden drilling conducted in Zone 3. The results are encouraging as they correlate with historical drilling and confirm the high grade zinc-copper mineralisation reported in the historic drill-holes.
The sixth hole, K3DD11_031, was drilled as a step-out hole with the objective of extending the mineralisation. The results confirm the extension of mineralisation at depth in the dip direction to the west of historic drillhole K97_157, indicating extension of mineralisation down-dip to the North-West.

Furthermore, rich zones of copper have been identified in holes K3DD11_022 ( 21m @ 2.32% Cu ) and K3DD11_030 ( 6m @ 2.06 % Cu ) outside of the high-grade Zinc intersections, which indicates the potential for further high grade copper mineralisation.
A complete tabulation of intersection results from these 6 drill holes is presented in Table 1 below.
DEFINITIVE FEASIBILITY STUDY
The Khnaiguiyah DFS is targeted for completion in Q1 2012.
Key DFS activities currently progressing are:
-
preparation of a JORC compliant resource estimate for the two main mineralised zones (Zone 2 and Zone 3);
-
metallurgical testwork on a master composite on Zone 2;
-
variability composites for both Zones 2 and 3;
-
an intensive field programme covering various environmental surveys and hydrological testing; and
-
general engineering and infrastructure activities.
It is anticipated that in the next few weeks grinding and flotation process design criteria will be delivered to Ausenco, thereby commencing the plant process design process for the Khnaiguiyah DFS.
Metallurgical Testwork – Zone 2
Initial locked cycle flotation test work results from the metallurgical testwork programme on Zone 2 master composite, based on a relatively coarse primary grind product size of P80 < 106μm, appear highly encouraging, with;
-
favourable kinetics and recoveries consistently in excess of 87% for copper and 91.5% for zinc; and
-
resulting concentrate grades of around 30% for Cu and 57% for Zn.
Testwork optimisation has now commenced, aimed primarily at maximising copper recovery and reducing the presence of zinc in the copper concentrate.
Initial indications based on comminution data in hand are that the Khnaiguiyah DFS ores are of moderate hardness of the order of 14kWh/t energy requirement during grinding.
