Judeira Prospect RC Drilling Update
Perth, Western Australia: Tiger Resources Limited (ASX/TSX: TGS, “Tiger”) is pleased to provide an update on the recently completed second phase of reverse circulation (RC) drilling at its Judeira prospect, within the mining licence area of the Kipoi Copper Project (PE533), in the Democratic Republic of Congo (DRC).
Highlights
Copper mineralisation intersected in 18 of the 22 RC holes completed in latest phase of drilling, with three holes ending in mineralisation at depths in excess of 150m. Strong down dip continuity confirmed.
The significant intersections include:
10m @ 1.58% Cu intersected in hole JUDRC030
36m @ 0.8% Cu intersected in hole JUDRC031
21m @ 0.58% Cu intersected in hole JUDRC033
22m @ 0.66% Cu intersected in hole JUDRC038
22m @ 0.46% Cu intersected in hole JUDRC042
43m @ 0.77% Cu intersected in hole JUDRC043
40m @ 0.56% Cu intersected in hole JUDRC044
16m @ 1.14% Cu intersected in hole JUDRC046*
17m @ 1.12% Cu intersected in hole JUDRC047
20m @ 0.82% Cu intersected in hole JUDRC048*
28m @ 0.69% Cu intersected in hole JUDRC049*
* Ended in mineralisation
Assay results confirm the continuity of copper oxide mineralisation down dip in the southern mineralised area at Judeira South and highlight continuous mineralisation on sections in the central area and northern limit of the Judeira North area.
Mineralisation remains open at depth in the southern region of Judeira South.
Follow up diamond drilling is planned for the first quarter of 2012.
The 22 hole RC drilling programme was designed to test for strike, width and depth extension of copper mineralisation identified by the first phase drilling completed in June this year at the southern and northern sections of the Judeira prospect.
An economic cut-off grade of 0.3% copper has been used for this second phase of RC drilling, reflecting the findings of the Scoping Study for the development of a Stage 2 solvent extraction electrowinning (SXEW) facility at Kipoi.
Judeira South
Hole JUDRC048 extended the broad copper oxide intercepts encountered in drill hole JUDRC023 (up dip), with the hole ending in mineralisation at 153m [see Section 1 Fig.3] This section shows strong continuity from surface to depths of at least 153m, with the mineralisation widening at depth.
Fifty metres to the northwest on Section 2, hole JUDRC046 also extended broad up dip intercepts with the hole ending in mineralisation at 160m, indicating significant scope for further mineralisation to be found at depth and further down dip in this area. [See Fig.4]
A further 100m to the northwest on Section 3, hole JUDRC049 ended in mineralisation at 153m after intercepting 28m @ 0.69% Cu, again demonstrating the depth potential and broad nature of the oxide mineralisation. [See Fig.5]
Judeira North
The southernmost section drilled at Judeira North included holes JUDRC030 & JUDRC031. [See Fig2, for northern collar locations]. Both holes intercepted mineralisation over intervals of 45m and 36m respectively, providing another target area for follow up drilling. The hill to the south of this section is untested due to its topography and contains artisanal workings, so there is good potential for further drilling to expand known mineralisation to the south and down dip in this area.
Drill holes JUDRC043 & JUDRC044 both encountered broad intercepts of mineralisation (see Section 1 of Judeira North), however hole JUDRC045 was ended prematurely because of drilling difficulties and failed to intercept the down dip extension to mineralisation that is believed to exist [See Fig.6].
While some of the holes only encountered narrow mineralised zones, it is believed that faults perpendicular to strike may be having an effect on the distribution of the oxide mineralisation. As a result mineralisation is often more extensive than expected down dip in certain areas, but pinches and swells along strike. It is expected that further drilling will demonstrate the increase of mineralisation at depth.
A follow up diamond drilling programme is planned for early 2012 and will target areas where mineralisation is open.
