DRILLING AT BOLLINGER CONFIRMS POTENTIAL SCALE ? Over 40 metres of massive and breccia sulphide intersected in Bollinger follow up hole – open in all directions ? Very strong DHEM conductor (conductor 6) identified to the southeast of this hole ? Drilling also confirms Nova connects to Bollinger via the mineralised feeder zone up to 30 metres thick ? Bollinger may also connect northward with conductor 5 (to be drilled) ? The discovery of significant massive sulphides in areas with no surface EM anomalies reaffirms the potential of the Eye ? Main part of gravity anomaly still to be drilled Sirius Resources NL (ASX:SIR) (“Sirius” or the “Company”) advises that it has intersected over 40 metres of massive and breccia sulphides in a hole drilled to follow up the initial Bollinger discovery hole (SFRD0167) on line 700N (see Figure 1). This indicates that the Bollinger deposit is substantial. Drilling has also confirmed that Nova is connected to Bollinger via the mineralised feeder zone. Four holes have so far been drilled to follow up the Bollinger discovery hole (SFRD0167). The new intersections are as follows: ? 55 metres of sulphide mineralisation from 423.2 metres, including 41.6 metres of massive and breccia sulphide from 436.9 metres in hole SFRD0258, located 60 metres west of the Bollinger discovery hole on the 700N line (see Figure 2). ? 118.2 metres of trace to stringer sulphide from 343 metres, including 30.2 metres of disseminated to stringer sulphide from 431 metres in hole SFRD0257, located 100 metres east of the Bollinger discovery hole on the 700N line.
? 32.1 metres of breccia and stringer sulphide from 383.15 metres in hole SFRD0256, in the feeder zone between Nova and Bollinger, 55 metres east of SFRD0253 on the 675N line. ? 21.5 metres of stringer and disseminated sulphide from 356.8 metres and 2.5 metres of massive sulphide from 403.5 metres in hole SFRD0254, in the feeder zone between Nova and Bollinger, 100 metres east of SFRD0256 on the 675N line. A fifth hole (SFRD0255) located approximately 190 metres southeast of the Bollinger discovery hole, whilst only intersecting weak mineralisation, has intersected the same geological sequence as Bollinger and down hole electromagnetic (DHEM) surveying has identified an extremely strong offhole conductor commencing to the southeast of SFRD0258 (containing 41.6 metres of massive and breccia sulphide) and SFRD0167 (the Bollinger discovery hole) (see Figure 3). This conductor is as strong as the Nova EM anomaly and is a priority for drilling. The mineralisation intersected to date at Bollinger may also extend northwards and be contiguous with the as yet untested conductor 5 (see Figure 3). The information available at this stage indicates that the Nova and Bollinger zones appear to be separate magma chambers linked by a thinner feeder zone, as shown in Figure 4. The discovery of massive sulphides in areas within the Eye that did not show up as EM anomalies in the previous surface EM survey is very important. This shows that the effective depth penetration range of the previous surface EM is limited to less than 300 metres and that any massive sulphides occurring deeper than this will have been invisible before now. In turn this means that the potential for massive sulphide zones within the Eye is much greater than previously thought. Drilling to date is still largely focussed on the margins of the gravity anomaly (see Figure 5). The core of this gravity anomaly will be tested as part of the ongoing exploration drilling program in parallel with the many other targets. Sirius’ Managing Director Mark Bennett said “the first follow up holes to the Bollinger discovery hole have confirmed the significance of Bollinger and its connectivity with Nova and also potentially with conductor 5 to the north. The strong EM conductor identified southeast of these holes suggests we may have yet to drill the sweet spot.” “Our plan of finishing the Nova drillout and immediately going hard on exploration whilst the Nova project team completes the first resource estimate is paying immediate dividends, and six rigs have now begun an intensive drilling campaign at Bollinger and adjacent targets within the Eye” he said. Nova Meanwhile, assays received for Nova infill holes continue to confirm the robust nature of the deposit (see Figure 3), including several significant intersections at the edges of the deposit, as follows: ? 37.38 metres @ 2.05% nickel and 0.41% copper from 282 metres in hole SFRD0219, located at the extreme northwestern edge of Nova. Sirius Resources ASX/Media Announcement 3 ? 18.75 metres @ 2.82% nickel and 0.68% copper from 50.85 metres in hole SFRD0243M, located close to surface at the extreme southwestern tip of Nova. ? 21.74 metres @ 4.37% nickel and 1.15% copper from 361.26 metres in hole SFRD0224, located towards the southeastern margin of Nova. ? 46.16 metres @ 2.73% nickel and 1.02% copper from 323.44 metres in hole SFRD0246, internal to Nova. ? 19.77 metres @ 4.62% nickel and 1.86% copper from 411.56 metres in hole SFRD0178, internal to Nova. ? 34.82 metres @ 2.51% nickel and 0.95% copper from 309.47 metres in hole SFRD0202, internal to Nova. ? 22.5 metres @ 3.01% nickel and 1.41% copper from 389.01 metres in hole SFRD0203, internal to Nova. The maiden JORC resource estimate for Nova remains on track for completion in March. Sirius is increasingly confident that Nova and Bollinger are part of a significant mineralised system, and a major exploration drilling program has commenced.
