Estrella Resources Limited (ASX: ESR) (Estrella or the Company) is pleased to provide shareholders with an update on follow-up drilling planned at Scotia East, 40km east of Ardea Resources Limited (ASX:ARL) major Goongarrie Ni/Co/Sc Project north of Kalgoorlie, Western Australia.

FOLLOW-UP RC PROGRAM
Three vertical 30m deep holes were previously drilled on an east-west cross section at Scotia East to test a high-grade cobalt occurrence identified in the Company’s digital database. All three holes intersected strong cobalt mineralisation almost exactly as predicted.
Results (at a 0.1% Co cut-off) include;
-
NCB0024: 7m at 0.21% Co and 0.68% Ni from 7m*
-
Including 1m at 0.42% Co and 0.75% Ni from 8m*
-
NCB0023: 11m at 0.16% Co and 0.53% Ni from 3m*
-
Including 2m at 0.33% Co and 0.58% Ni from 4m*
-
NCB0022: 2m at 0.18% Co and 0.47% Ni from 4m*
These complement the very encouraging results from historic drilling, which include:
-
CBR172: 8m at 0.22% Co and 0.69% Ni from 7m*
-
Including 1m at 0.41% Co and 0.61% Ni from 7m*
-
CBC019: 12m at 0.23% Co and 0.67% Ni from 8m (4m composites)*
A full listing of drill details and results can be found in Table 1.
Follow-up drilling is now planned north and south of the currently drilled cross section (see figure 2). POW approval has been granted allowing for the testing of up to 1km of potential strike length of nickel cobalt mineralisation. The Company intends to undertake drilling as soon as possible.
ABOUT THE COBALT MINERALISATION
Cobalt is hosted in a saprolitic clay horizon developed over an ultramafic package, similar in style to other projects in the region. However, Scotia East may have key advantages due to its very shallow depth, starting at just 2m below surface, its high grade, up to 0.4% Co, and its consistently high cobalt to nickel ratio.
Mineralisation is developed over a NNE striking ultramafic belt approximately 2.6 km in length, with a gabbro package to the east and a granite (or possibly leucogabbro) to the west.

OTHER TARGETS
Interrogation of historic reports and digital datasets has identified several other high priority cobalt targets for follow-up work. Field investigation will begin on these after drilling is completed at Scotia East.
Ravensgate
An internal report prepared by Ravensgate on behalf of Australian Nickel Mines commissioned in 2010 collated all the work completed at Carr Boyd pre-2010. This had included several phases of exploration targeting and planning by Defiance Mining, Titan Resources, Yilgarn Mining, and others. Several lateritic Ni/Co targets were identified in the report, including;
T9 (Gossan Hill)
Lateritic nickel mineralisation identified in historic drilling. Cobalt not assayed.
T14 (Colreavy)
Shallow drilling has identified grades above 1% Ni. Low Cu values suggest laterite style Ni mineralisation. Cobalt not assayed.
T15 (Colreavy East)
Anomalous Ni values in drilling of weathered ultramafic komatiite units. Nickel mineralisation appears to be laterite Ni style. Cobalt not assayed.
Colreavy is comprised of a variably weathered ultramafic belt with at least 20km of strike extent, which has never been explored for cobalt.
Surface Geochemistry Dataset
Although a clear majority of the surface geochemistry samples collected in the region are not assayed for cobalt, several anomalies have been identified in the samples that have. The area south of Scotia East shows a clearly anomalous cobalt zone trending NNE/SSW ( see Figure 4. Over page ), confirming geological interpretations.
A second highly anomalous area occurs near the Tregurtha area trending towards Drinkwater, although the strong correlation with copper in this area suggest this is at least partly a primary signature rather than a lateritic enrichment.
==> picture [145 x 61] intentionally omitted <==
The anomalies closer to Drinkwater and Corner prospects appear to be lateritic signatures and are worthy of follow-up.
Other lateritic style anomalies occur at Gossan Hill, Porphyry Hill, and the Schneider/Granites area.

COBALT MARKET
The cobalt market has remained strong. At the time of writing the price was still above AUD 90,000/t.
ABOUT THE PROJECT
Scotia East is located within the Carr Boyd Layered Complex (CBLC) and the Colreavy Komatiite sequence located immediately west of the CBLC. The area is prospective for lateritic nickel and cobalt mineralisation over certain deeply weathered ultramafic areas of the stratigraphy. Scotia East is in a Tier 1 jurisdiction approximately 80km north north-east of Kalgoorlie Western Australia. An all-weather haul road accessible to ESR under a granted miscellaneous license connects the Project to the Goldfields Highway via Scotia, passing through Ardea Resources’ Goongarrie Project area.
