TIGER RESOURCES INCREASES SASE CENTRAL INDICATED RESOURCE BY 173%
Perth, Western Australia:
Tiger Resources Limited (ASX: TGS) is pleased to announce an upgrade
to the Indicated and Inferred Resources at its Sase Central deposit, part of the 100%-owned
Lupoto Copper Project in the Democratic Republic of Congo (DRC). The resource estimate was independently completed by Cube Consulting Pty Ltd (Cube) and updates the maiden estimate completed in March 2011 following additional diamond drilling (DD) and reverse circulation (RC) drilling completed since then.
Highlights
Indicated Resource of 9.6Mt @1.39% Cu containing 134,000 tonnes of copper (and
5,000 tonnes of cobalt)
Indicated Resource increased by 173% (from 49,000 tonnes copper in March 2011)
Inferred Resource of 2.8Mt @ 1.21% Cu containing 34,000 tonnes of copper (and
1,000 tonnes of cobalt)
Combined Indicated and Inferred Resource of 168,000 tonnes of copper
Higher grade cut -off of 0.5% Cu used to estimate the resource update (0.3% Cu cut-off previously)
Resource upgrade drilling
The updated mineral resource estimate is based on 51 DD holes totalling 7,779m and 50 RC
holes totalling 4,901m. In addition, 448 air core (AC) holes totalling 16,743m were completed but these holes were not used for the estimation; they do, however, provide a guide to the interpretation of the copper mineralisation domain.
The RC and DD drilling data utilised for the updated resource estimate is variable ranging from 50m collar spacing on 50m north-south sections to sections with in -fill drilling at a 25m x 50m hole spacing.
The 2013 Sase mineralisation interpretatio n was guided by the underlying lithology, weathering and structural considerations as well as the distribution of assays. A mineralised copper domain was interpreted on 50m spaced north-south cross sections between 508,200mE to 508,800mE. A combination of geological logging to define the key geological and weathering surfaces and a nominal lower cut -off grade of 0.2% was used to define the mineralised copper domain. The copper mineralisation domain was utilised for the estimation of cobalt, calcium, magnesium and sulphur quantities. The copper mineralisation domain contains dolomite and siltstone lithologies, and oxide, transition and fresh weathered material.
Tiger Managing Director Brad Marwood said the upgraded resource estimate demonstrated
greater confidence in the Sase Central deposit and was calculated to a higher cut-off grade than the previous estimate.
“The Sase Central deposit will be a vital part of Tiger’s plans to further extend the life of the
Stage 2 SXEW development at Kipoi,” he said.“
A feasibility study for the Sase Central deposit is expected to be completed later this year and, if the outcome of the study is positive, Tiger will apply to convert the Lupoto exploration permit to an exploitation permit during 2014.”
