PERTH, Western Australia, July 8 /CNW/ - Tiger Resources Limited
(ASX/TSX: TGS) ("Tiger" or the "Company") is pleased to announce the
completion of an updated resource estimate for Kipoi Central by Cube
Consulting Pty Ltd. The revised resource estimate is constrained within the
area that forms the first three years of production within the Stage 1 Pit
- The high grade component of the Kipoi Central orebody that will
provide feed for the Heavy Media Separation ("HMS") plant during the
first +3 years of production has been upgraded to a Measured and
Indicated Resource of 2.86Mt at 8.1% Cu containing 232,000 tonnes of
copper (compared to the previously reported Inferred Resource of
3.2Mt at 7.2% Cu containing 230,000t of copper).
- The conversion of estimated metal from Inferred only to Measured plus
Indicated is approximately 100%.
- The resource estimate incorporates all results from the 25mx25m
infill drilling programme.
- The significant upgrade in resource category gives a high level of
confidence in the quality of the orebody and continuity of the high
- The updated resource estimate will form the basis of the definitive
feasibility study into the proposed Stage 1 development of the
Upgraded Mineral Resource Estimate for Kipoi Central
The Directors of Tiger are extremely pleased with the result of the
revised and upgraded resource estimate as it provides significant support for
the strategy of developing a 900,000tpa Stage 1 mining operation at Kipoi
Central producing 32,000tpa of copper metal over an initial 3 year period from
a conventional open pit mine.
The new resource estimate is based on the results of a 25m by 25m infill
drilling programme carried out over the high grade section of mineralisation
at Kipoi Central that was reported as part of the initial Inferred Resource
Estimate undertaken by Cube Consulting Pty Ltd in March 2008.
The total of the Inferred resource reported in March 2008 was 13.4Mt at
3.3% Cu containing 439,000 tonnes of copper, 20,000 tonnes of cobalt and
1,416,000 ounces of silver. Included in the resource was a high grade
component (also to inferred resource status), determined by a lower cut off
grade of +5% Cu, of 3.2Mt at 7.2% Cu containing 230,000 tonnes of copper,
5,200 tonnes of cobalt and 441,000 ounces of silver.
In order to determine the feasibility of a mining project at Kipoi the
Company undertook a 25x25m infill drilling programme to better quantify the
area of mineralisation within the proposed Stage 1 development. The drilling
was carried out between 8755950mN and 8756350mN and within the proposed
Stage 1 pit design. The Measured component of the updated resource is made up
entirely of either oxide or partially oxidised mineralisation.
All the results from the infill drilling which included 63 new diamond
holes (8,345m) and 6 new Percussion holes (577m) were incorporated into the
updated resource model.
Cube Consulting Pty Ltd has estimated the following Measured and
Indicated Resources for Kipoi Central between 8755950mN and 8756350mN.

The primary objective of the resource estimate was to undertake an update
of the resource model (March 2008) with specific focus on the area of interest
that forms the first three years of proposed production at Kipoi Central.
Tiger is earning a 60% interest in the Kipoi Project. Estimates of copper and
cobalt were undertaken. The Resources have been classified in accordance with
the current JORC Code.
The following key points summarise the modelling method:
- Mineralised domain interpretations were based on a combination of
detailed geological modelling, alteration characteristics and grade.
- Statistical analysis of 5 metre downhole composite data. High-grade
assay cuts were applied where appropriate.
- Data was domained by host lithologies and weathering classification.
- Variography was used to characterise the spatial continuity within
the mineralised domains and to determine appropriate estimation
inputs to the interpolation process.
- 3D block models were generated for each domain in Kipoi Central. The
block model was constrained by the interpreted mineralised volumes.
- Grade interpolation was carried out using Ordinary Kriging (OK) into
25mN x 25mE x 5mRL parent cells. A uniform conditioning (UC) estimate
of copper resource was undertaken on a selection of grade cut offs
under an SMU assumption of 5m x 5m x 2.5m.
- Search strategies were optimised using quantitative kriging
- Flagging of oxide, transitional and fresh material and assignment of
- Model depletion by best available topographical surface incorporating
surface mining activity.
- Cube Consulting were not requested to consider any possible expansion
of the Inferred Resource as drilling is still ongoing to test for
extension of known mineralision along strike to the South, down dip
and to the west in the footwall to the delineated mineralisation.
Kipoi Central is one of five known copper deposits hosted in a 12km long
fragmented sequence of mineralised Roan sediments that have been mapped within
boundaries of the Kipoi Project in which the Company is earning a 60%
In addition to resource drilling at the Kipoi Central deposit, resource
drilling has also been undertaken at the Kipoi North, Kileba and Judeira
deposits. The conceptual target for exploration is to define oxide and
sulphide resources in excess of 1 million tonnes of contained copper by end of
2008 to support future production of 100,000 tpa of copper metal.
On the satisfactory completion of the Stage 1 definitive feasibility
study, the Company intends to immediately commit to a feasibility study to
evaluate the economic viability of constructing a Solvent Extraction and
Electrowinning ("SXEW") plant producing 35,000tpa of copper metal in
conjunction with the continuation of the Stage 1 HMS plant capacity of
35,000tpa. The SXEW plant will form Stage 2 of the proposed mining plan for
the Kipoi Project, and would be scheduled to come on stream within 3 years of
the start of the HMS operation. It is envisaged that ore from Kipoi Central
and the other deposits within the Kipoi project would be processed at the
Stage 2 development phase.
