TROPICANA JV SIGNIFICANT NEW GOLD INTERCEPTS AT THE BOSTON SHAKER OPEN CUT AND HAVANA DEEPS UNDERGROUND TARGETS
New true width BOSTON SHAKER intercepts include:
BSRC 189 - 17m @ 4.6 g/t Au from 75m TPRC 068D - 16m @ 4.9 g/t Au from 379m BSRC 243 - 12m @ 4.3 g/t Au from 95m
New true width HAVANA DEEPS intercepts include:
HDD 033 - 16m @ 9.7 g/t Au from 369m HDD 032 - 14m @ 9.0 g/t Au from 416m
The 2.1km Havana Deeps down plunge step out hole (TFD 204) returned 2m @ 1.9 g/t Au from 1,180m indicating the Havana Gold alteration system is very large with multi-million ounce potential.
Ind e pendence G roup NL (I G O) is plea s ed to anno u nce further significant d rilling results from the Tro p icana JV (IGO 30%, AngloGold A s hanti 70% - Manager) as part of t h e Boston S haker and Ha v ana Deeps d rill outs. Bot h Boston Sh a ker and Havana Deeps have the p o tential to add significan t value to th e Tropicana Gol d Project. T h e Project w a s approved by IGO and AngloGold A shanti in N o vember 2010.
Sig n ificant mineralisation associated wit h the greater Tropicana/Havana gol d system ha s now been inte r sected ove r a 5km stri k e length, wi t h further drilling planne d to determine whether the system con t inues along strike beyo n d the fault-t e rminated n o rthern boundary of Bos to n Shaker and south of the Havana op e n pit (eg. C rouching Ti g er 11m @ 5.3 g/t Au). Drill testing beneath th e proposed Ha v ana open c u t has confir m ed robust thicknesses a nd grades e xtend at le a st a further 800 metres do w n plunge of the open pi t floor, with t he minerali s ed system e xtending a t least a furt h er 1,300m bey o nd this do w n plunge.
BOSTON SHAKER
Drilling of the B o ston Shak e r discovery (see 17 March 2010 A S X Release) , located ap p roximately 360 m north-east of the Tro p icana dep o sit (Figure 1), has now been com p leted on a 5 0m x 50m grid , with 25m x 50m infill d rilling conti n uing. Mine r alisation ha s been defi n ed over a 7 00m strike len g th and rem a ins open do w n dip.
Ass a y results a re yet to b e received, however r e cently rec e ived result s have both confirmed con t inuity of mi n eralisation w ithin the currently defin e d system and extende d higher gra d e zones at dep t h (eg. TPR C 068D 16m @ 4.9 g/t Au from 37 9 m and BS D 008 8m @ 8.1 g/t Au f rom 242m) (Table 1) .

HAVANA DEEPS
The Joint Venture has com p leted a Sco p ing Study t o continue t e sting the e c onomic pot e ntial of the Ha v ana Deeps t arget. The aim of the S tudy was to determine w hether hig h -grade sho o ts continue ben e ath the pr o posed Hav a na open c u t and whet h er ore deri v ed from b u lk underground mining met h ods could be mined and blended with open- c ut ore afte r the compl e tion of the high-grade star t er pits. The study includes several phases of de e p drill testing.
To d ate gold mineralisation has been in t ersected in excess of 800m down p lunge from t he base of the planned o p en pit, so m e 570m v ertically be n eath surfa c e (Figure 1) . Recently received sig n ificant inter c epts from this program a re presente d in Table 2.

A “super-deep” step-out hole (TFD204) to scope out the down dip potential a substantial distance from known mineralisation was completed. The hole confirmed that the Havana mineralised system continues at least 2.1km down plunge from the proposed pit floor (1,000m vertically) returning 2m @ 1.9 g/t Au within a 10m zone of pyrite-biotite alteration typical of Tropicana/Havana gold mineralisation alteration (Figure 2) .
Further drilling will be needed to determine if the discrete thicker higher grade shoots extending immediately beneath the Havana open cut also continue to these depths and beyond.

BACKGROUND
Inde p endence G r oup NL (IGO ) has a 30% contributing i nterest in th e Tropicana J o int Venture m anaged by Ang l oGold Ashanti. The Tropi c ana JV com p rises appro x imately 15,0 0 0km[2] of pro sp ective tenur e covering a strik e length of ov e r 350km.
The Tropicana p r oject was ge n erated by I G O and joint v entured to A n gloGold Ashanti on 30 J a nuary 2002. The first major di s covery withi n this extensi v e tenement p ackage is t h e Tropicana d eposit, com p rised of the Tro p icana and H a vana Zones, on which a B ankable Fea s ibility Study w as complete d in Novemb e r 2010. The boa r ds of both I G O and Angl o Gold Ashant i have subse q uently appr o ved develop m ent of the P roject. Key Proj e ct paramete r s are outline d below.
