26 SEG NEWSLETTER No 65 • APRIL 2006... from 25Exploration Reviews (Continued)EXPLORATION REVIEWSfrom 241 m, and 30 m @ 9.2% Cu. Aninferred resource for Einasleigh is840,000 t at 3.6% Cu, 0.19 g/t Au, and16 g/t Ag. The inferred resource at thenearby Kaiser Bill prospect is 11 Mt at0.84% Cu, 0.15 g/t Au and 6.3 g/t Ag.CopperCo Ltd. reported that drillingat the Lady Annie project yielded anintersection <strong>of</strong> 22 m @ 6.7% Cu from173m downhole below the Lady Annieoxide resource. Other intersectionsincluded 23 m @ 0.45% Cu from 103 mand 10 m @ 0.82% Cu from 144 m.Recent drilling at Mount Kelly faultzone near Flying Horse gave results <strong>of</strong>24 m @ 4.7% Cu, 18 m @ 4.22% Cu,and 25 m @ 1.58% Cu.Matrix Metals Ltd. reported 28 m @2.93% Cu from 235 m at its McCabedeposit south <strong>of</strong> Cloncurry. This drillingwas to test extensions to the existingmineralization. The latest follow updrilling gave 18 m @ 3.5% Cu, and 8 m@ 3.39% Cu.Current exploration in Queensland isbeing assisted by the Department <strong>of</strong>Natural Resources, Mines and Water’s$20M Smart Exploration initiativewhich is currently running groundgravity and airborne geophysics surveysin the Mount Isa region to expand discoveryin one <strong>of</strong> the world’s largest copperand base metals province.NEW SOUTH WALESThe search for Intrusion Related GoldDeposits (IRGD) in New South Waleshas accelerated, particularly in the Sn-W terrains <strong>of</strong> central and eastern NewSouth Wales. In the Lachlan Fold Belt(LFB), Moly Mines Dargues Reefdeposit is a recognized member <strong>of</strong> thisdeposit type, and farther west CullenResources is searching for similardeposits and their W analogues. In theNew England fold belt (NEFB) the onlyrecognised IRDG deposit is the minedoutTimbarra Au-Bi-Mo deposit, howeverMalachite Resources Phoenix discoveryalso displays characteristicstypical <strong>of</strong> this deposit type.At Boonoo Boonoo in the northernNEFB, Macmin Silver has drilled fourAu-Ag lodes with best results <strong>of</strong> 5 m @3.45 g/t Au and 133 g/t Ag at the Star<strong>of</strong> Hope Lode. Farther east, DrakeResources has recently completed adrilling program which has emphasizedthe potentially valuable zones <strong>of</strong> Zn ina previously defined resource below theStrauss pit at Drake. Intersections includedrill holes DP19 (20 m @ 6.2 g/t Au and2.03% Zn from 17 m depth, including 2m @ 9.1% Zn) and DP20 (11 m @ 3.8 g/tAu and 3.93% Zn from 6 m depth).In the LFB, very significant highgradeassays have been received for twoinfill holes in Triako Resources’ HeraAu-base metal deposit. <strong>Economic</strong> modelling<strong>of</strong> the project during the prefeasibilitystudy concluded that the returnfrom developing the Hera project ismost sensitive to changes in headgrade, in particular the gold headgrade. These new high-grade assays willfurther enhance the economics <strong>of</strong> theproject.Also in the LFB, results received byAlkane Resources from diamond drillingcontinue to add high-grade interceptswithin the Wyoming One resource.Intercepts include holes WY 838D (9 m@ 9.57 g/t Au from 207 m including 5m @ 15.6 g/t gold from 208 m) and WY839D (15 m @ 4.43 g/t Au from 99 m,and 6 m @ 7.98 g/t Au from 151 m).Visible gold was observed in severalintervals and these will be checked byscreen fire assay. These results follow onfrom the recent discovery <strong>of</strong> a new highgradestructure intersected by WY 831D,which returned an intercept <strong>of</strong> 66 m @19.49 g/t Au from 268 m.News from the Broken Hill provincehas been scarce lately with all the operatorsvery busy. However, another majorhas recognized the potential for worldclassbase metal deposits with TeckCominco entering into a JV with a syndicate<strong>of</strong> local NSW-based companiesover the Stephens-Centennial project.In the NE section <strong>of</strong> the province, theKoonenberry belt is considered highlyprospective, in part due to the recentmapping work by the GeologicalSurvey <strong>of</strong> NSW. Black Range Mineralshas reported high-grade Cu intersectionsat its Flagship prospect at BrokenHill, including 7 m @ 5.51% Cu located2 km west <strong>of</strong> the existing workings.SOUTH AUSTRALIAJoint venture partners AdelaideResources and Iluka Resourcesannounced the discovery <strong>of</strong> significantheavy mineral sand occurrence at theTripitaka prospect in the Eucla basin. Amineralized zone up to 2 km in lengthand over 1 km in width has been identified,with drill traverse lines identifyinga central core <strong>of</strong> heavy mineral sandscontaining 68% zircon. Some <strong>of</strong> thebetter intersections include: 21 m at5.6% HM from 1.5 m below surface, 21m at 4.1% HM from 1.5 m below surface,19.5 m at 3.5% HM from 6 mbelow surface.Gunson Resources reported theresults <strong>of</strong> a deep drilling program at itsChianti Cu prospect at Mount Gunsonin the Gawler craton. Hole MGD 34,completed to a depth <strong>of</strong> 600 m returned2 m at 3.4% Cu and 0.2 g/t Au from549-551 m. The mineralization occursas bornite and chalcopyrite in hematiterichgranite breccia.Havilah Resources intersected newCu-Au-Mo mineralization at a PIRSAsupportPACE drilling project 6 km S <strong>of</strong>its Kalkaroo Cu deposit. Best resultsinclude 63 m @ 0.4% Cu and 69 m @0.67 g/t Au. The Kalkaroo deposit has aresource estimated <strong>of</strong> 70 Mt @ 0.47%Cu, 0.46 g/t Au, and 124 ppm Mo.Marathon Resources has commenceda 19-hole drilling program targetingthe Hodgkinson, Mt Gee, andArmchair-Streitberg U prospects locatedin the Mt. Painter inlier in the NorthernFlinders Ranges. Best results from thefirst three diamond holes from theHodgkinson prospect include 12 m @0.46% uranium oxide from 51 m and 2m @ 0.23% uranium oxide from 53 m.Maximus Resources have commenceddrilling to explore the downdippotential <strong>of</strong> the historic Bird in Handgold mine in the Adelaide Hills. Initialresults include 9 m (true width estimatedat 6.5 m) at 31.2 g/t Au, 58.3 g/tAg, 5.8% Pb, and 4.6% Zn from 158 m.Metals Exploration acquired theWingellina Ni laterite project in theMusgrave Range province and undertookat 20,000 m RC drill program.Wingellina contains an estimated 227Mt <strong>of</strong> ~1% Ni and 0.07% Co in a predominantlylimonitic host assemblageassociated with a layered dunitic intrusivecomplex. Drilling results include184 m @ 1.05% Ni, and 0.09% Co from8 m and 132 m at 1.18% Ni and 0.08%Co from surface.NORTHERN TERRITORYRenison Consolidated Mines has completeda 20-hole diamond drilling programat its Tom’s Gully gold mine,located 90 km south east <strong>of</strong> Darwin.The resource estimate for the deposit is
