Preliminary results from second phase of Apex drilling at Apollo Hill main zone
Hampton Hill Mining NL is pleased to advise that preliminary results from its second Apex Minerals NL drilling program at the Apollo Hill Joint Venture have been received (see table below). This program, which focused on the Main Zone of mineralisation, has successfully extended the mineralised system a further 70 metres to the north and down plunge, albeit at a lower apparent grade than that reported from previous drilling carried out to the south. Key results from these holes are summarised below, and shown on the attached cross sections and long projection:
• 1 metre @ 7.25g/t gold from 215 metres and 1 metre @ 5.33g/t gold from 236 metres in AAHD16, drilled on section 17680N, some 70 metres north of all previous drilling on section 17610N;
• 1.4 metres @ 6.71g/t gold from 340.6 metres and 2.27 metres @ 3.62g/t gold from 357.3 metres in AAHD15, drilled on section 17680N, some 120 metres down dip of AAHD16 (above) and 70 metres north of the previous intersection of 10 metres @ 6.51g/t gold in AAHD10 on section 17610N.
A diamond hole was also drilled down the interpreted dip of the mineralisation to better define the internal distribution of oblique gold-bearing quartz veins within the overall envelope of alteration and its influence on grade distribution. The most significant intersections from this hole are summarised below and are also shown on the attached long projection:
• 6 metres @ 5.17g/t gold from 40.7 metres, and 4 metres @ 4.02g/t gold from 65 metres, within a broad lower grade zone of 59.5 metres @ 1.41g/t gold from 15.5 metres in AAHD23, drilled down interpreted dip to check internal continuity;
• 6 metres @ 4.35g/t gold from 178 metres and 2 metres @ 7.63g/t gold from 276 metres within a further broad lower grade zone of 42 metres @ 0.71g/t gold from 128 metres, also in AAHD23.
Where this hole remained within the alteration zone it successfully confirmed the presence of mineralisation, with several higher grade zones being associated with more intense quartz veining.
It should be noted that these results are based on standard 50 gram fire assays which may not necessarily reflect the true grade of samples in which grained gold is present, as is the case at Apollo Hill. Consequently key samples will be re-assayed using the 1000 gram Leachwell technique which is most suited to this style of mineralisation. Final assays will be reported separately if they are materially different from the preliminary assays quoted here.
Preliminary three dimensional modelling of the Main Zone mineralisation shows that it remains open down plunge to the north, but on northernmost drilling sections is partially affected by a footwall shear zone which appears to have smeared and perhaps truncated the mineralisation. If this is the case the mineralisation may be offset to some degree.
Exploration Program
The next stage of work at Apollo Hill will comprise detailed 3D modelling of the mineralisation and the fault which is interpreted to fault out the northern part of the mineralisation to determine optimum locations for further extensional drilling. In parallel with this, reconnaissance drilling will commence during the first quarter of 2007 to test additional targets identified beneath the transported cover along strike.
